RELATED APPLICATION 
       [0001]    This application claims the benefit of and priority to U.S. Provisional Application No. 61/482,972, entitled “Systems and Methods For Advanced Lighting System Management” and filed on May 5, 2011, which is incorporated herein by reference. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present application is generally related to lighting systems. In particular, the present application is directed to systems and methods for controlling and modulating intensity of the light emitted by a light emitting device. 
       BACKGROUND 
       [0003]    Lighting systems may include light emitting devices organized in various configurations depending on the illumination applications. The lighting system may include a heat sink to help manage heat from the light emitting device. The heat sinks for many lighting systems are designed for the worst case scenario or maximum temperatures, even if they occur rarely or infrequently. 
       SUMMARY 
       [0004]    The present disclosure is directed to an active thermal management solution that has multiple innovations and advantages. In some aspects, the design of the active thermal management (ATM) device is not a threshold clamp and instead, is a non-linear equation that proportionally changes relative to the dimming input. In some aspects, the innovation of the ATM design is how ATM works while the light is being dimmed. The design anticipates overheating by reducing power before the product gets to the maximum temperature threshold. The design also may include an equation that predicts the LED die temperature as a function of product case temperature. The ATM may operate responsive to one or more of a plurality of profile or power curves. As the power curve goes down, the design gets less aggressive in its power reduction with heat. For example, when one dims the light to a reduced intensity, the design knows that both the power in the LED is less, and thus, the temperature rise due to thermal resistance is less (based on degree C./W), and also knows that the product heat sinking is more influential. 
         [0005]    Products that use such an innovative ATM design may require less heat sinking than competitors without this ATM solution. With the present solution, the lighting system can provide 100% intensity for what may be considered ‘typical’ ambient temperature and then back off the power for higher than typical temperatures. In this aspect, active thermal isn&#39;t just about protecting the product—it&#39;s about maximizing the intensity of the product. Without this ATM design, one would need to design for their worst case ambient temperature. So if a manufacturer knows the light could reach 50 C ambient, worst case, then the manufacturer would have to design for this scenario, even if that only happens 10× a year. With the ATM of the present solution, a manufacture can design the heat sink for 30 C and then dim the lights when it may be needed. The dimming can be very discrete, so the user doesn&#39;t notice and the dimming per any dimming curves still works as such curves should. 
         [0006]    In some aspects, the present invention is directed to a method for managing intensity to a light source responsive to a temperature of a light fixture comprising the light source. The method includes receiving, by a device such as embodiments of an active thermal management device described herein, an incoming signal for a lighting fixture comprising a light source. The incoming signal identifies a first intensity for the light source. The method also includes measuring, by the active thermal management device, a temperature of the lighting fixture and determining, by the active thermal management device, a second intensity from a function of both the first intensity and the temperature of the lighting fixture. The method further includes outputting, by the active thermal management device responsive to the determination, a second signal as input to the light source, the second signal identifying the second intensity. 
         [0007]    In some embodiments, the method includes receiving, by the active thermal management device, the incoming signal comprising a dimming signal. In some embodiments, the method includes measuring, by the active thermal management (ATM) device, the temperature of air within an enclosure of the lighting fixture. In some embodiments, the method includes measuring, by the active thermal management device, the temperature of an enclosure of the lighting fixture. In some embodiments, the method includes predicting a temperature of a LED of the light source based on the measured temperature of the light fixture and using the predicted LED temperature as the temperature. In some embodiments, the method includes determining the second intensity from the function comprising an intensity curve comprising a curve of a selection of second intensity values based on values of the first intensity and the temperature. 
         [0008]    In some embodiments, the method includes the ATM device determining the second intensity from the function comprising a non-linear relationship between the first signal and the second signal. In some embodiments, the method includes the ATM device determining the second intensity from the function comprising a temperature compensation factor applied to a dimming level of the first intensity. 
         [0009]    In some embodiments, the method includes the ATM device outputting the second intensity to reduce power to the light source prior to reaching a predetermined threshold of a maximum temperature. In some embodiments, the method includes the ATM device outputting the second intensity to reduce power to the light source while dimming the light source. In some embodiments, the active thermal management device is enclosed within the light fixture. In some embodiments, the active thermal management device comprises a diode for measuring the temperature. 
         [0010]    In some aspects, the present solution is directed to a system for managing intensity to a light source responsive to a temperature of a light fixture comprising the light source. The system includes a device, such as embodiments an active thermal management device described herein, that receives an incoming signal for a lighting fixture comprising a light source. The incoming signal identifies a first intensity for the light source. The system also includes a temperature measuring component of the active thermal management device that measures a temperature of the lighting fixture.

In operation of the system, the active thermal management device, responsive to the determination, outputs a second signal as input to the light source. The second signal identifies the second intensity. 
         [0011]    In some embodiments, the active thermal management device receives the incoming signal comprising a dimming signal. In some embodiments, the temperature measuring component measures the temperature of air within an enclosure of the lighting fixture. In some embodiments, the temperature measuring component measures the temperature of an enclosure of the lighting fixture. In some embodiments, the processor predicts a temperature of a LED of the light source based on the measured temperature of the light fixture and uses the predicted LED temperature as the temperature. In some embodiments, the processor determines the second intensity from the function comprising an intensity curve comprising a curve of a selection of second intensity values based on values of the first intensity and the temperature. In some embodiments, the processor determines the second intensity from the function comprising a non-linear relationship between the first signal and the second signal. In some embodiments, the processor determines the second intensity from the function comprising a temperature compensation factor applied to a dimming level of the first intensity.

         [0133]    At step  330  the first device operates responsive to the second duty cycle of the second signal. The first device operating responsive to the second duty cycle of the second signal may be similar to the first device operating responsive to the duty cycle of the signal. In a number of embodiments, the first device operates or performs an operation of the first device or any other device  110  in response to the duty cycle of the signal received. In many embodiments, the second duty cycle of the second signal is different than the duty cycle of the signal. The first device may change or modify the operating of, or operation performed by, the first device, the second device or any device which operates in response to the second duty cycle of the second signal. In a number of embodiments, the first device instructs a second device or a plurality of devices to perform in response to the second duty cycle of the second signal. The operating may comprise emitting a light having a specific brightness, intensity, spectral range or pulse duration. In a variety of embodiments, the operating comprises supplying electricity or power to a component or a plurality of components of the first device or any number of devices  110 , the electricity or power responsive to the duty cycle or the second duty cycle. 
         [0134]    At step  335  the first device detects that at least a portion of the second duty cycle of the second signal comprises a second instruction. The first device may detect the second instruction in a same way as detecting the instruction. In many embodiments, the second instruction is detected differently than the first instruction. In a number of embodiments, the second instruction comprises a number of data bits  215  positioned within a specific time interval within time interval  205 . In a variety of embodiments, a portion of the second duty cycle of the second signal comprises a portion of the second instruction. In many embodiments, the first device detects that at least a portion of the second duty cycle of the second signal comprises a portion of the second instruction. 
         [0135]    At step  340  the first device performs, responsive to the detection, a function based on the second instruction while maintaining operating responsive to the duty cycle of the second signal. In some embodiments, the first device performs a function based on the second instruction without maintaining operating responsive to the second duty cycle. The function may be any action executed upon receiving an instruction. In a number of embodiments, the function is any function or any operation performed by the first device or any other device  110  described herein. In some embodiments, the first device performs the function based on the second instruction and maintains operating of the first device responsive to the second duty cycle. In a variety of embodiments, the first device performs the function based on the second instruction and maintains operating of a second device responsive to the second duty cycle. Sometimes, the first device performs the function by any device  110  based on the second instruction for any device  110  and maintains operating of any device  110  in response to the second duty cycle. In some embodiments, the first device instructs a second device to perform a function and operates or maintains operating of the second device in response to the second duty cycle. Operating may refer to performing operation of any device  110  described herein. 
       C. Status Assignment of Lighting System Components 
       [0136]    Further referring to figures  FIG. 2A  and  FIG. 2B  discussed in the earlier sections,  FIGS. 2A and 2B  further refer to embodiments within which light sources  110  may transmit among each other instructions to assign statuses of masters and slaves. In one example, a first lighting system  100  component, such as a lighting device  110  may have a status of a master. The master first lighting device  110  may transmit a first information using data bits  215  or  220  to a second lighting system  100  component, such as a second lighting device  110 . The second lighting device component having a slave status. The second lighting system  100  component receives the first information and in response to the first information adjusts the status of the second lighting system  100  component to a master status. The second lighting system  100  component having a master status transmits a second information using data bits  215  or  220  to the first lighting system  100  component. The first lighting system  100  component receives the second information and in response to the second information adjusts the status of the first lighting system  100  component to a status of a slave. 
         [0137]    In some embodiments, light source  110 B, having a master status, transmits a first information using data bits  215  or instruction bits  220  to light source  110 A which has a slave status. Light source  110 A receives the first information and in response to the first information adjusts the status of the light source  110 A to a master status. Light source  110 A, having a master status, transmits a second information using data bits  215  or instruction bits  220  to the light source  110 B. Light source  110 B receives the second information and in response to the second information adjusts the status of the first light source  110 B to a slave status. In a number of embodiments, light source  110 A, having a master status, transmits a third information via data bits  215  or instruction bits  220  to a plurality of lighting system components, one of which is light source  110 B. The third information transmitted by light source  110 A comprises address  127 B. The plurality of lighting system components receive the third information and light source  110 B receives the third information. Light source  110 B matches address  127 B within the third information to address  127 B of the light source  110 B. In some embodiments, light source  110 B, in response to the third information, adjusts the status of light source  110 B to a status of a master. In a number of embodiments, light source  110 B, in response to the address  127 B matching the address  127 B of the light source  110 B, adjusts the status of light source  110 B to a status of a master. In a plurality of embodiments, light source  110 B, in response to the received third information and in response to the address  127 B matching the address  127 B of the light source  110 B, adjusts the status of light source  110 B to a status of a master. 
         [0138]    In some embodiments, a plurality of light sources  110 , each having a status of a master or a slave, communicate using a same connection  105  component, such as a wire or an electrical current conducting line. In such embodiments, any of the light sources  110  may become a master or a slave. Sometimes, the plurality of light sources  110  communicating over a same connection  105  component include only a single master, while all other light sources  110  have a status of a slave. In such embodiments, one of the light sources  110  having a status of a slave pulls the voltage potential within the connection  105  component low for a period of time, such as a microsecond, a millisecond or a second. The light source  110  having a status of a master interprets the low voltage signal in the connection  105  component as a signal to change status from master to slave. The light source  110  having a status of a master accepts the status of a slave, and the light source  110  which pulled the voltage potential low accepts the status of a master. Thus the signal across the connection  105  component signals a change in the status of one or more light sources  110  communicating over the same connection  105  component. In some embodiments, the signal that changes the status of one or more lighting system components may be a high voltage potential signal, a low voltage signal, an impulse, a digital pattern, a ground signal, or any other analog or digital signal transmitted over connection  105 . 
         [0139]    In a number of embodiments, when a group of light sources  110  are all off, upon being turned on, each one of the group of light sources  110  turns on with a status of a master. In some embodiments, upon receiving a signal that a light source  110  having a master status, also called a master, already exists, a light source that has just turned on changes its own status to a status of a slave. Thus, when a group of light sources  110  are all turned on at once it is ensured that at least one master exists. In some embodiments, light source  110  upon turning on and automatically changing its own status to a master, the light source  110  listens for a period of time if there is another master on the network. If the light source  110  does not receive any messages that there is another master on the network, the light source  110  remains the master. 
         [0140]    In some embodiments, a lighting system  100  component receiving instruction from a sender assembles received bits  215  from a plurality of periods  205 . In some embodiments, the lighting system  100  component receiving information from a sender parses the bits and bytes of the received information and forms instruction, data or commands. In a plurality of embodiments, lighting system  100  component receiving instruction from a sender interprets the forms instructions, data or commands and implements the same formed instructions, data or commands. 
         [0141]    Therefore, in many embodiments, lighting system  100  components use bidirectional digital pulse width modulated communication to transmit and receive information. Furthermore, in some embodiments, lighting system  100  components use digital pulse width modulated communication to control performance and functionality of one or more lighting system  100  components. Light brightness, also referred to as intensity, in many embodiments is controlled, communicated or instructed using a pulse width modulated communication. In many embodiments, light brightness or intensity is controlled, communicated or instructed using a duty cycle of a period  205 . Pulse width modulated signals may therefore be referred to as transport mechanism of the digital communication between lighting system  100  components. 
         [0000]    D. Lighting System Intensity Control with Digital Patterning and Color Mixing 
         [0142]    Referring back to  FIG. 2A  and  FIG. 2B , embodiments of systems and methods for controlling intensity or brightness of light devices  110  using digital patterns are depicted. A digital pattern may be any order or any formation of data  210 , data bits  215  or instruction bits  220 . A digital pattern may include an order or a formation of a specific number of data bits within a period  205 . Data bits, such as data bits  215 , may include bits having a high value, or a digital value of 1, and a number of data bits having a low value, or a digital value of 0. Data bits may form a duty cycle within the period  205 . The duty cycle formed by the data bits of the digital pattern may identify the intensity or brightness of the light emitted. Duty cycle may be determined by summing up all time durations of the digital patterns for which data bits had high values within the time interval. For example, if the signal comprising a data stream made up of digital patterns has data bits having high values 70 percent of the time within a time interval, the duty cycle for the time interval may be 0.7. The duty cycle may be determined by summing portions of the signal within the time interval for which the signal was high and dividing the signal by the total duration of the time interval. In some embodiments, duty cycle is determined based on a sum of time durations of the signal having low values. 
         [0143]    Data bits  215  may be transmitted via a connection  105  within one or more time intervals  205 . A number of data bits having a value of 1 (and/or a value of zero) within the time interval may determine the intensity of light or brightness of light emitted by the light device  110 . The intensity may be determined for the duration of that time interval. A digital pattern may include an order or a formation of data bits  215  or instruction bits  220  within a predetermined number of concatenated periods  205 . For example, a stream of data bits  215  may be transmitted to a light device  110  within a chain of a predetermined number of periods  205 , such as for example 128 periods  205 . Each period  205  may include a separate digital pattern. A lighting device  110  receiving the data stream may calculate a duty cycle for all of 128 periods  205  using all the digital data patterns within each period. The duty cycle of the 128 periods may indicate the brightness or intensity at which light device  110  will emit. In one instance, duty cycle of 128 periods may be 0.8, indicating that the light device  110  will emit at 80% of it&#39;s maximum brightness. 
         [0144]    A digital pattern may comprise a ratio of high to low values which encode or identify an intensity or brightness of light. The intensity or brightness of light emitted may defined by a total number of bits having a value of 1 within a period of time per a period of time. Digital patterns may include one or more predetermined patterns of data bits  215  that are oriented to have any high value signal to low value signal ratio. In some embodiments, the ratio of high signal to a total duration of period may encode or identify the brightness or intensity. For example, if a period  205  has six bits of data having a value of 1 and two bits of data having a value of zero, the intensity or brightness may indicate 6/8 of maximum intensity or brightness for that period  205 . 
         [0145]    In some embodiments, a digital pattern may identify a specific ratio of bits having high values to bits having low values within a period  205 . A specific ratio may include a duration of time for which a portion of a period  205  includes high values, such as digital bits with a value of 1 divided by the entire time duration of period  205 . Similarly, the specific ratio may include a duration of time for which a portion of the period  205  includes low values having a digital value of zero divided by the entire time duration of period  205 . The specific ratio may identify a duty cycle. The duty cycle may be proportional or inversely proportional to the brightness or intensity of the light emitted. Similarly, the specific ratio of the signal may include a ratio of a duration of time for which signal is high in relation to the duration of time for which the signal is low. An algorithm may be used to identify the intensity or brightness based on the ratio of the duration of time for which the signal is high in relation to the time duration for which the signal is low. A digital pattern may identify or form an average value of the signal within one or more periods  205 . In some embodiments, a digital pattern forms an average value of the bits within a period  205 . The average value of the bits within a period  205  may determine or identify the intensity or brightness of the light emitted. Any of the duty cycle, average signal, and the specific ratios may be formed by digital signals, as well as analog signals, pulses, PWM signals, encoded data bit signals, encoded digital number signals, or any other type and form of signals having at least a high value and a low value. 
         [0146]    A digital pattern may be random or predetermined and may include any number of digital bits of any pattern of format. Digital bits may be formed by a switch or a transistor. The switch or the transistor may transmit high and low signals. The high and low signals may be received by the light devices  110 , and may be processed by filters to determine the specific ratios, average values or the duty cycles. In one example, a digital pattern may include a predetermined total number of data bits of which 10 data bits have a high value within a period  205 . The brightness or intensity of the light emitted by the light device may be determined by dividing 10 bits with the total predetermined number of data bits within the period that can be transmitted within the period  205 . In some embodiments, digital pattern may include a predetermined order of bits. In other embodiments, digital pattern includes a random order of the bits. 
         [0147]    Digital pattern may be altered to accommodate instructions or information transmitted to the light device  110  using instruction bits  220 . For example, if a transmission includes a number of bits having a high value within a period  205 , the digital pattern may add a number of bits that accommodates the already transmitted instruction bits  220  within the period  205 . If transmission bits  220  carry an instruction to the light device  220 , the digital pattern within the same period  205  may include a number of bits determined by subtracting the number of instruction bits having a high value from the originally intended digital pattern bits. Then, a digital pattern that has a number of data bits that is determined by subtracting the number of already sent instruction bits having a high value from the total intended number of data bits having a high value. As such, the number of bits having a high value from the instruction within the period  205  would be included in the overall digital pattern, thereby maintaining the duty cycle unchanged even if an instruction is transmitted within same period  205 . Using this technique, a digital pattern may maintain the intensity or brightness of the light device  110 , while an instruction could be transmitted within the period  205  without affecting the total number of data bits having a high value. In a similar embodiment, in techniques where data bits determining intensity have a low value, a number of bits having the low value would be maintained within the period to accommodate the transmitted instruction. 
         [0148]    In some embodiments, a digital pattern comprises a number of data bits  215  or instruction bits  220  which is equal over all periods  205 . As the data bits are transmitted through a plurality of periods  205 , the lighting device  110  may continuously receive intensity information and instructions via digital patterns of the periods  205 . The digital patterns may instruct the lighting device  110  to emit light at the intensity or brightness indicated by the digital pattern of each period. As periods may include predetermined durations of time a continuous data stream of digital patterns may be received to maintain desired intensity. Each digital pattern may include a predetermined number of data bits or a varying or random number of data bits within each time period. In some embodiments, periods  205  may have a varying number of data bits  215  or instruction bits  220 . As periods  205  may be indicated by a specific signal, such as one or more bits, pause or an impulse, periods  205  may vary in time duration as well as the number of bits transmitted. In some embodiments, digital pattern affects or defines duty cycle of a period  205 . 
         [0149]    A digital pattern of a period  205  may include any number of data bits, such as between 1 and 1024 data bits. In some embodiments, a digital pattern includes more than 1024 data bits within a period  205 . In further embodiments, a digital pattern includes between 4 and 512 data bits, such as 4, 6, 8, 10, 12, 16, 20, 24, 32, 48, 64, 96, 128, 256 and 512 data bits. In one example, eight data bits  215  may be transmitted within a period  205 . An 8-bit digital patterning for generating the digital pattern may include any number of sequences or distinct digital patterns of any variation of 8 bits. In some embodiments, a digital pattern includes a single bit having a high value, or a value of 1, and seven remaining bits within the period  205  having a low value or a value of zero. In these embodiments, duty cycle of the period  205  may be ⅛. In some embodiments, a digital pattern includes two out of eight bits having a high value or a bit having a value of 1, and six remaining bits having a value of zero or a low value. In these embodiments, duty cycle may be ¼. In still further embodiments, a digital pattern may include 4 bits of high value and 4 bits of low value. In these embodiments, duty cycle may be ½. These bits may be ordered in a predetermined fashion to maintain a desired duty cycle. In some embodiments, digital patterns are randomized while maintaining the desired duty cycle. For example, a duty cycle of ½ may be generated by an 8-bit digital pattern of 01010101, 00001111, 11001100, 01100110 or any other digital pattern having 4 high bits and 4 low bits within a period  205 . Similarly, any digital patterns may be generated, including five, six, seven or eight bits having high values. As period  205  may include any number of bits, such as a total of 16 bits, a digital pattern may have any number of variations to accommodate any number of bits. In the example of a digital pattern for a 16 bit period  205 , a duty cycle of 15/16 may be implemented by a pattern of 0111111111111111, 1110111111111111, 1111111101111111, 1111111111111101, or any other configuration of the similar kind Such concepts may apply to embodiments of digital patterns of any number of bits  215  within a period  205 , such as a 4 bit digital pattern, 6 bit digital pattern, 8 bit digital pattern, 10 bit digital pattern, 12 bit digital pattern, 16 bit digital pattern, 24 bit digital pattern, 32 bit digital pattern, 64 bit digital pattern or a digital pattern comprising any number of data bits within one or more periods  205 . 
         [0150]    A digital pattern may also include a numbering format or a code. In some embodiments, a digital pattern includes a data bits identifying a number. For example, a digital pattern may include code 0001 identifying the number 1, 0010 identifying a number 2, 0100 identifying a number 4 or a 1000 identifying a number 8. In further embodiments, a digital pattern may include code 0101 identifying a number 5 or a 1010 identifying a number 10. The light source  110  may receive the codes and interpret the numbers accordingly. The light source may determine a value of 10 to mean an intensity of 10/16 of the maximum intensity of the light for the lighting device. In some embodiments, the light source may determine the value of 10 to mean a level 10 of a total of 16 levels of intensity for the light emitted. Similarly, a digital pattern may include any type and form of code that may be mapped, encoded, decoded or interpreted by the light source  110  to identify a brightness or intensity of the light emitted. 
         [0151]    Referring now to  FIGS. 4A-B  embodiments of a digital pattern having a smaller number of bits within a period  305  is illustrated.  FIGS. 4A-B  illustrate digital data transmitted between light sources  110 A and  110 B divided into periods  305 , each of which includes 8 bits of data. Period  305  include a period of time within which 8 bits of data  215  are transmitted, sent or received by lighting device  110 . Similarly, period  305  may be modified so that any number of data bits are transmitted within the period  305 , such as 2, 4, 6, 8, 10, 12, 14, 16, 24, 32, 64, 128, 256, 512 or any other number of data bits. In some embodiments, period  305  is a period  205 . In further embodiments, period  305  is a duration of time within which 8 bits are transmitted. In still further embodiments, a period  205  includes a plurality of periods  305 . A period  305  may include a number of bits of data one or more lighting system  100  components use or receive in a single instruction or a single instruction set. Periods  205  or  305  may have any duration of time between 1 microsecond and 100 seconds. Periods  205  or  305  may include one or more durations of time, such as 0.1 microsecond, 1 microsecond, 10 microseconds, 50 microseconds, 100 microseconds, 1 millisecond, 10 milliseconds, 50 milliseconds, 0.1 seconds, 0.2 seconds, 0.5 seconds, 1 second, 10 seconds or a 100 seconds. In some embodiments, 8-bit period  305  is a period of time defined by, determined by, or corresponding to a duration of time within which lighting system  100  components communicated via connection  105  transmit 8 bits of data  210 . In some embodiments, period  305  is a period of time defined by, determined by, or corresponding to a duration of time within which lighting system  100  components communicated via connection  105  receive any predetermined number of data bits, such as 8, 16, 24, 32, 48, 64, 96, 128, 256, or 512. Periods  305  may include same or different durations of time. In some embodiments, some periods  305  are longer or shorter than other periods  305 . In further embodiments, all periods  305  are of a same predetermined length of time. Each period  305  may include a same predetermined number of data bits. In some embodiments, some periods  305  include a number of data bits that is different than the number of data bits of another period  305 . A period  205  may include a predetermined number of periods  305 . For example, a period  205  may include a duration of time within which a predetermined number of periods  205  is enclosed. Each period  205  may include a digital pattern having any number of bits. In some embodiments, some periods  305  of a period  205  may have different average value of the data bits within the period  205  from the average values of data bits of other periods  305  of the same period  205 . Similarly, some periods  305  of a period  205  may include a different number of data bits having a high value from a number of data bits having a high value within other periods  305  of the same periods  205 . As such, a total duration of time for which the signal has a high value within a period  305  may vary from other periods  305  of the same period  205 . A ratio of a duration of time within which the signal has a high value per a total duration of a period  305  may be also referred to as the duty cycle of the period  305 . Duty cycles of some periods  305  of a period  205  may differ from the duty cycles of other periods  305  of the same period  205 . 
         [0152]    In one example, a period  205  may include 128 periods  205  each of which further includes an 8 bit digital pattern. The period  205  along with all the bits from each of the periods  305  within the period  205  may form or identify a specific ratio of a number of bits having a high value to a number of bits having a low value within the period  205 . The period  205  may have a duty cycle determined by a total duration of time within the period  205  for which the signal is high (or for which the bits have a value of 1) divided by the total duration of time of the period  205 . The duty cycle of the period  205  may be used to scale the maximum intensity or brightness of the light emitted by the light source  110  to the desired intensity. A new period  205  immediately following the period  205  may identify another duty cycle for a changed or modified intensity or brightness. The light source may modify the light intensity emitted based on the new duty cycle for the new period  205 . Should the light source  110  receive an instruction or a command within one or more periods  305  of a period  205 , digital patterns of other periods  305  within the period  205  may be modified by the pattern generator of the communicator  125  of the sender to maintain the desired intensity for the light source  110  at a predetermined level. Using the real time update via a stream of bits divided into periods  305  within a period  205 , light devices  110  may receive real-time updated intensity or brightness while receiving instructions or commands for other functions or purposes of the light device  110 . 
         [0153]    Still referring to  FIGS. 4A-B , an embodiment of a digital pattern determining intensity or brightness via a period  315  for a 16-bit transmission is illustrated.  FIGS. 4A-B  illustrate a light source  110 A connected to light source  110 B via connection  105 . Connection  105  transmits information or communication transmitted between light sources  110 A and  110 B.  FIG. 4B  illustrates embodiments where digital data transmitted between light sources  110 A and  110 B divided into 8-bit periods  305  and 16-bit periods  315 . In some embodiments, 8-bit period  305  may be modified to accommodate a 16-bit period  315  for a finer control of the brightness and intensity range. As such, instead of dividing the total brightness in 8 shades of brightness, the brightness intensity may be divided into 16 shades, or any other number of shades. In this example, a 16-bit period  315  is a period  205  whose time length is tailored to allow transmission of 16 bits of data  215  within the period  205 . 
         [0154]    The plurality of periods  305  or periods  315  within a period  205  may include any digital pattern. In one example, a period  305  of a period  205  may have 4 bits having a high value and 4 bits having a low value, while another period  305  from the same period  205  may include 8 bits having a high value and no bits having a low value. Duty cycles of periods  305 , average values of signal within the period  305  or specific ratios of the high to low bits within periods  305  may vary while the overall duty cycle, average value or specific ratio of the period  205  as a whole may be maintained at a particular predetermined level. In further example, a period  205  comprising 50 periods  305  may include one or more periods comprising instructions and commands for the light device  110 . The periods  305  within which the instructions were transmitted may have duty cycles altered from other duty cycles. (Duty cycles of periods  305  may be defined as durations of time for which the signal had a high value divided by the total duration of time of period  305 ) A pattern generator of the communicator  125  sending the data bits to the light device  110  may compensate for the transmitted instructions by increasing or decreasing the number of data bits having a high value in order to maintain the intensity or brightness of the entire period  205  at a predetermined level. The pattern generator may keep a track of the number of data bits having a high value within a period  205 . As instructions and commands are transmitted to the light device  110 , pattern generator of the communicator  125  of the sender may determine how many data bits having a high value need to be added in the periods  305  following the periods  305  that included the instructions. By keeping track of the overall number of data bits  215  within a period  205 , intensity and brightness may remained controlled by the number of data bits having a high value even when the instructions are transmitted within the period  205 . 
         [0155]    In some embodiments, lighting system  100  components, such as light source  110 B and light source  110 A, communicate using data bits  215 , instruction bits  220  or a combination of data bits  215  and instruction bits  220 . The light devices  110  may receive real time adjustments for the brightness or intensity for each light source  110  via the stream of data bits per each receiving period  205 . Sometimes, lighting system components using 8-bit periods  305  are capable of transmitting or receiving information twice as fast. In such embodiments, lighting system components, such as light sources  110 A and  110 B 16 bit send or transmit a 16-bit digital pattern within an 8 bit period. In further embodiments, light source  110 B communicates with light source  110 A transmitting or receiving information within 8-bit periods  305 . In many embodiments, light source  110 B transmits a 16-bit digital pattern comprising data bits  215  or instruction bits  220  within an 8-bit period  305  to light source  110 A. Light source  110 A receives 16-bit digital pattern within the 8-bit period  305  and in response to the received 16-bit digital pattern adjusts, changes or maintains the intensity of the light emitted by the light source  110 A. 
         [0156]    Duration of periods  205 ,  305  or  315  may be adjusted to affect intensity. In some embodiments, periods  205 ,  305  or  315  are increased or decreased to modulate average intensity of a light source  110  receiving the information. In some embodiments, preceding periods  305  or  315  are increased or decreased and succeeding periods  305  or  315  are adjusted accordingly to maintain a desired intensity over a  205  period. 
         [0157]    Digital patterns comprising any number of bits may have duty cycles of periods  205 ,  305  or  315 , defined by a number of bits having values of 1 or 0. In many embodiments, two different digital patterns comprising a same total number of bits within a period, such as period  205 ,  305  or  315 , may have a same or a different duty cycle. The duty cycle of a period may be determined by a ratio of the number of bits having a high value to the number of bits having a low value of that same period. Duty cycle of a period may also be determined by summing up all durations of time for which the signal (data bits) had a high value and divide this sum of the durations of time with a total duration of time of the period. Duty cycle may also be determined by taking an average value of all portions of the signal (bits having a high value and bits having a low value). Duty cycle may be used to identify or determine the brightness or the intensity of the light emitted. The light device  110  may include a filter within a controller  120  or a communicator  125  that determines the duty cycle and controls the brightness or intensity of the light emitted. The filter may determine the duty cycle of each period  205  by counting the instructions from within the period  205 . In some embodiments, the filter of the controller  120  or the communicator  125  of the receiving light source  110  may determine the duty cycle of the period  205  while not including the instructions within the period  205 . 
         [0158]    Digital patterns within periods  305 ,  315  and  205  may be used to control light intensity or color mixing of light sources  110  emitting different color light or having different spectral ranges. In some embodiments, lighting system  100  comprises a plurality of light sources  110  each emitting a light of a different spectral range or a different color. The plurality of light sources may be within a single lighting fixture, or they may comprise separate lighting devices. The lighting system  100  may include a light source  110 A emitting a red light, a light source  110 B emitting a green light and a light source  110 C emitting a blue light. In such a configuration, the lighting system  100  may use digital patterns within periods  305 ,  315  and  205  to govern or control the overall color of light emitted by all of the light sources  110 A-C. For example, digital patterns may govern the intensity of each of the light devices  110 A-C in order to establish a specific hue of light, such as a white color for example. The lighting system may transmit digital patterns and vary the number of data bits within each period of time to produce any particular color by mixing light at intensities determined via digital patterning from each one of the sources  110 A-C. The light sources  110 A-C may receive digital patterns within varying durations of time, or varying periods  205  for each of the light source  110 A-C in order to produce the white light. The light sources  110 A-C may receive real-time updates of the intensity at periods of  205  and receive instructions within periods  305  which are within periods  205 . Sometimes, a lighting system  100  controls the total color output of the light emitted by all three light sources  110  by using a feedback to adjust intensity of some light sources via digital patterning in order to adjust the total hue of the output light. In one example, a plurality of light sources  110 A-N may each emit light of a different spectral range or a different color. In such embodiments, a lighting system  100  component controlling the light sources  110 A-N may emit separate data streams comprising digital patterns within periods  305  and  205  to each of the light sources  110  in order to control the color rendering or the total color output produced by the light sources  110 A-N. 
         [0159]    Referring now to  FIG. 4C , an embodiment of steps of a method  400  for modulating intensity of light emitted by a lighting device using a digital pattern is depicted. In some embodiments, method  400  relates to a method of color mixing of a plurality of light sources emitting different light color. At step  405  of the method  400 , a controller receives or generates an instruction for a remote lighting device and a setting for an intensity of light to be emitted by the remote lighting device. At step  410 , the controller generates a signal that comprises the instruction, a time period and a duty cycle of the signal within a time interval of the time period. The duty cycle of the signal may be based on a sum of portions of a digital pattern of the signal which have a high value within the time interval. At step  415 , the remote lighting device receives the signal via a wire used for supplying electrical power to the remote lighting device. At step  420 , the remote lighting device establishes intensity of light or performs color mixing of a plurality of lights emitting different colors of light, based on a determination of the duty cycle of the signal within the time interval. At step  425 , the remote lighting device emits light based on the determined intensity of the light or mixes colors of light based on intensities of each of the plurality of light sources emitting a different color of light. At step  430 , the remote lighting device takes or implements an action based on the instruction from the signal. 
         [0160]    Further referring to step  405 , a controller acquires an instruction and a setting for a remote lighting device. The remote lighting device may include a single light source or a plurality of light sources. The instruction may include an instruction for a single light source or for each of the plurality of light sources. In some embodiments, the controller generates the instruction or the setting. In further embodiments, the controller receives the instruction or the setting from another lighting system component. In still further embodiments, the controller generates an instruction or a setting based on a configuration set by a user. In further embodiments, the controller receives an instruction or a setting from a user input or an instruction file. In some embodiments, a controller generates instructions based on a program, script, prior instruction file or a user input identifying actions to be taken by the remote lighting device. 
         [0161]    The acquired instruction may include any type and form of a command for an action implemented by a lighting device. In some embodiments, the instruction includes a command to send an error message. In other embodiments, the instruction includes a command to send an acknowledgement message or an alert when an address of an instruction matches the address of the lighting device. In further embodiments, the instruction includes a command to send an acknowledgement if ambient light detector of the lighting device is active. In still further embodiments, the instruction includes a command to send an acknowledgement if a presence of an object is detected in the vicinity of a light switch enclosure. 
         [0162]    In further embodiments, the instruction includes a command to set a brightness value of the remote lighting device or a light source within the remote lighting device, such as a green light source, blue light source or a red light source of the remote lighting device. In further embodiments, the instruction includes a command to use an external source for PWM signal to control the intensity of the light. In further embodiments, the instruction includes a command to use a value sent to the remote lighting device as a maximum intensity or maximum brightness value of the remote lighting device. In still further embodiments, the instruction includes a command to turn the light emitted by the remote lighting device off by dimming. 
         [0163]    In some embodiments, the instruction includes a setting for the remote lighting device as a master or a slave. In still further embodiments, the instruction includes a setting for the remote lighting device as a member of a group or a zone. The setting for the remote lighting device may include a setting for an intensity or brightness of the light to be emitted by the remote lighting device. In some embodiments, the setting identifies an intensity or brightness of light relative to the maximum intensity set for the remote lighting device. The setting may identify the dimness or brightness of light to be emitted by the remote lighting device for a predetermined duration of time. 
         [0164]    At step  410 , the controller generates a signal comprising the instruction, a time period and a duty cycle of the signal within a time interval. The controller may generate a signal comprising one or more digital patterns. Digital patterns may be generated to compensate for any instructions to be embedded with the signal. Digital patterns may further be generated to ensure that a duty cycle within a time interval remains at a predetermined level. In some embodiments, digital patterns comprise one or more portions of the signal having high and low values within a time interval. In further embodiments, a digital pattern that includes a plurality of high and low data bits is located within a predetermined time interval of a plurality of time intervals of a time period of a signal. Each time interval may or may not include an instruction. Each time interval may include one or more digital patterns generated to ensure that the duty cycle of the signal remains at a level indicating a predetermined light intensity for the time interval, regardless of the presence of the instruction within the time interval. The duty cycle of the signal may be based upon a sum of portions of one or more digital patterns having a high value within a predetermined time interval. In one embodiment, the controller generates the signal that has a digital pattern that includes digital bits having high values and low values within a time interval of the time period. In some embodiments, digital patterns may include any variation or order of high and low data bits within a time interval. The digital pattern may be generated such that a sum of time durations of the digital bits having high values within a time interval divided by the duration of the time interval corresponds to the setting for the intensity of the light. 
         [0165]    In one example, a generated digital pattern includes a sum of time durations of the signal having high values 65 percent of the time within the time interval. In such example, the sum of the time durations having high values divided by the total duration of the time interval may equal 0.65. This result may correspond to the setting for the intensity of light to be emitted by the remote lighting device identifying an intensity of about 65% of the maximum light intensity. 
         [0166]    In other embodiments, digital patterns of the signal may be generated to identify any intensity of light. The intensity may be in percentages of the maximum light intensity, in Watts, Watts per meter square, lumens, nits or any other unit of light intensity or brightness. In some embodiments, a signal generator of the controller generates the signal comprising the digital patterns and a plurality of time intervals within a time period. The signal may be generated to further include the instruction into one or more of the time intervals of the time period of the signal. In some embodiments, the controller generates a signal to be comprised by a first time interval of the time period while generating one or more digital patterns of the first time interval. 
         [0167]    The digital patterns may be generated to account for the number of the portions of the instruction having high values so that the total duty cycle within the first time interval remains at a predetermined level regardless of the instruction being present. In further embodiments, the controller generates the signal to include the instruction in the first time interval of the time period. In such embodiments, digital patterns are included into other time intervals of the time period to compensate or account for the instruction and maintain the duty cycle within the period at a predetermined level. 
         [0168]    At step  415 , the remote lighting device receives the signal via a wire of the remote lighting device. In some embodiments, the remote lighting device receives the signal via a power supplying line or an active wire of a standard power distribution system powering the lighting device. In other embodiments, the remote lighting device receives the signal via a common wire of a traditional power distribution system. In further embodiments, the remote lighting device receives the signal via a ground wire, or a conductive sheathing of a cable. In still further embodiments, the remote lighting device receives the signal via a wireless signal, such as a WIFI signal or a radio signal. In yet further embodiments, the remote lighting device receives the signal via a network, such as a computing network or a communication network of the plurality of lighting devices. In still further embodiments, the remote lighting device receives the signal via an infrared channel. In still further embodiments, the remote lighting device receives the signal via an optical channel, such as a fiber optic or an optical wireless receiving system. The remote lighting device may receive the signal via a controller or a communicator. In some embodiments, the remote lighting device uses a signal processor or a signal processing unit to receive and process the signal. In other embodiments, controller filters the signal using filters, such as frequency filters, power filters or optical filters. The filtered signal may be processed for the duty cycle and for the instructions for the remote lighting device. 
         [0169]    At step  420 , the remote lighting device establishes intensity of light based on a determination of the duty cycle of the signal within the time interval. The remote lighting device may establish the intensity based on a determination of the duty cycle of the signal within the time period. In some embodiments, the remote lighting device determines the ratio of the sum of the portions of the digital patterns within the time interval having high values and a duration of the time interval. In other embodiments, the duty cycle is determined based on a ratio of the sum of the portions of the digital patterns within a plurality of time intervals of the time period and the entire duration of the time period. In some embodiments, a signal processor of a controller of the remote lighting device processes the signal to determine the duty cycle. The signal may be processed using any type of function, script or an algorithm operating of the signal processor to determine the duty cycle. In further embodiments, the controller of the remote lighting device determines the duty cycle. In further embodiments, the communicator of the remote lighting device determines the duty cycle within the time period. In still further embodiments, the controller of the remote lighting device screens for any instructions within the received signal and determines the duty cycle of the signal. In other embodiments, the remote lighting device determines the intensity of light in terms of the Watts of the light emitted. In other embodiments, the remote lighting device determines the intensity of light in terms of Watts per unit of area. In some embodiments, the remote lighting device determines the intensity of light by determining the duty cycle within each single time period. In other embodiments, the remote lighting device determines the intensity of light by determining the duty cycle over a plurality of time periods. In some embodiments, the remote lighting device determines the intensity of light by determining the duty cycle over a plurality of time intervals within a single time period. In other embodiments, the remote lighting device determines the intensity of light by determining the duty cycle within each individual time interval of each individual time period. In further embodiments, the remote lighting device determines the intensity of light in terms of the relative light intensity of the remote lighting device, such as the maximum light intensity. For example, the remote lighting device may determine the intensity of light based on the duty cycle identifying 0.85 or 85% of the maximum light intensity of the remote lighting device. 
         [0170]    At step  425 , the remote lighting device emits light based on the determined intensity of light. In some embodiments, the remote lighting device emits light based on the determined ratio. In further embodiments, the remote lighting device multiplies the ratio with the maximum intensity to determine the intensity of light at which the remote lighting device will emit. In further embodiments, the remote lighting device continuously receives the signal and determines the intensity for each time period of the signal. In such embodiments, the remote lighting device updates or adjusts the intensity of the light emitted in real-time. For example, in an instance where a time period comprises time a duration of a millisecond, the intensity of the light emitted may be determined for the millisecond. The intensity of light at which the remote lighting device would operate the following millisecond may be determined based on the duty cycle of the signal within the following time period. In further embodiments, the remote lighting device maintains the intensity of light until a signal comprising a different duty cycle within a time period or time interval is detected. 
         [0171]    At step  430 , the remote lighting device takes an action based on the instruction. In some embodiments, the remote lighting device sends an error message out in response to the instruction. In other embodiments, the remote lighting device sends an acknowledgement message or an alert when an address of an instruction matches the address of the lighting device in response to the instruction. In further embodiments, the remote lighting device sends an acknowledgement if ambient light detector of the lighting device is active. In still further embodiments, the remote lighting device sends an acknowledgement if a presence of an object is the object is detected in the vicinity of a light switch enclosure. In further embodiments, the remote lighting device sets a brightness value of the remote lighting device or a light source within the remote lighting device. In some embodiments, the remote lighting device sets a brightness or intensity value for a green light source, a blue light source or a red light source within the remote lighting device. In further embodiments, the remote lighting device begins to use an external source for PWM signal to control the intensity of the light. In further embodiments, the remote lighting device begins to use a value sent to the remote lighting device as a maximum intensity or maximum brightness value of the remote lighting device. In still further embodiments, the remote lighting device turns the light emitted by the remote lighting device off by dimming. In some embodiments, the remote lighting device sets a status for the remote lighting device as a master or a slave in response to the instruction. In still further embodiments, the remote lighting device sets the remote lighting device as a member of a group or a zone in response to the instruction. The remote lighting device may implement any instruction received or set any configuration or setting in response to the instruction received from the signal. Any portion of the controller of the remote lighting device may receive and process the instruction. In some embodiments, a communicator of the remote lighting device processes the instruction. The remote lighting device may implement any action or a function instructed by any instruction of a command received. 
         [0172]    In one example, a lighting device, such as a standard fluorescent lighting fixture or a source comprising a plurality of light emitting diodes is installed in an office, a building or at a home. The lighting device may include a single color light source or a plurality of light sources, each of which may emit light of a different color. The lighting device may be used in communication with one or more other lighting devices which may use controllers to send control signals coordinating operations between the light sources. The intensity of light emitted by a lighting device, or a light source, may be controlled via a received signal that includes one or more digital patterns indentifying the intensity or brightness. The signal may be delivered to the lighting device via standard wiring components commonly used for providing power to the lighting fixtures. Such standard wiring components may include electrical wires or power lines used for providing electrical power for the light sources. More specifically, the signal may be delivered via traditional wires, such as active lines, common lines or ground lines of the standard power distribution electrical wiring system. The signal may include analog or digital components and may include any type, form or format of signal. The signal may comprise digital patterns that may be made up of pulse width modulated signals, square wave signals, datagram, data packets, or any other type or form of digital information. The signal may further comprise a stream of data bits divided into time intervals, each comprising one or more portions of the signal. The portions of the signal may include digital patterns identifying intensity or brightness of the light to be emitted by the remote lighting device receiving the signal. In some embodiments, digital patterns identify a duty cycle within a time interval. Such duty cycle within the time interval may be based on a sum of all time durations of the signal for which the signal is high within the time interval. The sum of the time durations may be divided by the total duration of the time interval to determine the ratio of the intensity. The ratio may be the ratio of the maximum intensity of light that can be emitted by the remote lighting device. The lighting device may filter and process the digital patterns and identify the intensity of the light from the digital patterns by determining the duty cycle or the ratio based on the duty cycle. The remote lighting device may emit the light as identified by the duty cycle or the ratio based on the duty cycle.

In still further embodiments, LED  405  is positioned on a wall of a room that is illuminated by a lighting device  110 . 
         [0181]    Gain circuit  470  may be any hardware, software or a combination of hardware and software that controls, modulates or maintains performance or operation of LED  405  or light detector  420 . Gain circuit  470  may include logic circuits, or software operating on one or more processors to control or manage how signals from the LED  405  are detected by light source  410 . Gain circuit  470  may utilize a fraction of light reflected by the transparent cover  460  towards the light detector  420  to maintain the light detector  420  within a specific detection range. In some embodiments, gain circuit  470  manages or controls detection of light detector  410  of any signal, including the signal from the LED  405  or from any other light source, such as for example an emitter of object  450 . In some embodiments, gain circuit may be comprised by any component of the non-contact switch  400 , such as an LED  405 , light detector  420 , LED controller  410  or detector controller  425 . Gain circuit  470  may be connected in a feedback loop with the light detector  420  or the LED  405 . 
         [0182]    The gain circuit  470  may maintain the light detector  420  at a specific detection threshold or detection range. The gain circuit may be configured to provide real-time adjustments to the light detector  420  so that the signal detected by the light detector  420  may be maintained within a specific operating range of the light detector  420 . In some embodiments, the gain circuit  470  maintains a feedback loop with the light detector  420  to maintain the detecting range of the light detector  420  at a specific detection range, such as slightly below a threshold level of the detection of the light detector  420 . As ambient light, such as background noise light, increases in intensity, the gain circuit  470  may compensate and adjust to still maintain the gain of the light detector  420  within the specific range. Following the adjustment by the gain circuit  470 , light detector  420  would still adjust and maintain the sensitivity to the presence of object  450 . For example, when there is a lot of ambient light in the room where non-contact switch  400  is installed, gain circuit  470  may decrease the gain of the light detector  420  to compensate for the increased ambient light. In the instance where the object  450  is brought within a specific distance from the non-contact device  400 , the reflected portion of the LED  405  signal may increase the amount of the detected signal slightly above the threshold. The light detector  420  may then detect the presence of the object  450  as the threshold has been exceeded by the portion of the signal reflected by the object  450 . Normally, the gain circuit  470  may compensate for any changes in ambient light by setting and maintain the light detector  420  within the detection range just below the detectable threshold. However, as the present object  450  reflects a substantial amount of light towards the light detector  420 , the gain circuit  470  may not compensate for such a great increase in light intensity fast enough and the object  450  may be detected by the light detector  420 . As such, gain circuit  470  may control the sensitivity of the signal detected by light detector  420  such that compensates for changes in ambient light or background noise but does not lose sensitivity to the presence of the object  450 . The gain circuit  470  may control the light detector  420  such that the light detector  420  it is not oversensitive to detect the presence of the object  450  when the object  450  is not present within a predetermined distance from the non-contact device  400 . The gain circuit of any of the LED  405 , LED controller  410 , detector controller  425  or light detector  420  may perform any functionality or include any embodiments of any of the gain circuits of the LED  405 , LED controller  410 , light detector  420  and detector controller  425 . 
         [0183]    In some embodiments, gain circuit  470  includes an average intensity filter, a frequency filter and a comparator. The average intensity filter of the gain circuit  470  may monitor the average intensity of the signal detected by the light detector  420 . The average intensity filter may further filter out intensity of signal that is below or above a predetermined threshold intensity. In some embodiments, average intensity filter may only allow the signals that are within a predetermined range of the average intensities to pass through the filter. For example, if average intensity of light received by the light detector  420  is below a predetermined intensity threshold, the average intensity may filter out the signal. As such, the average intensity filter may filter out signals outside of the predetermined range. Just as with average intensity filter, the frequency filter of the gain circuit  470  may filter out any signal that is outside of a predetermined frequency range. In some embodiments, the frequency signal filters out signals that have carrier frequency outside of the allowed frequency range. In some embodiments, the carrier frequency range of allowed signals may be any signals that have pulses or carrier frequency between 30 and 50 kilohertz. In some embodiments, the carrier frequency range of allowed signals may be around 40 kilohertz, such as 41 or 42 kilohertz for example. Comparator of the gain circuit  470  may compare the signals that passed through the average intensity filter and the frequency filter against a threshold. The comparator may compare the signal filtered by the average intensity filter and the frequency filter against a predetermined threshold or a predetermined threshold range. If the comparator detects that the signal exceeds the threshold the object  450  is detected. Similarly, in set-ups where the comparator compares the signal that is lower than a predetermined threshold, the object  450  is detected if the signal is lower than the predetermined threshold. Gain circuit  470  may use any one of, or any combination of, the average intensity filter, frequency filter and a comparator together with any automatic gain controller circuit to control the detection of the light detector  420 .

For example, a gain circuitry of the LED controller  410  may maintain the output at a specific threshold or within a specific range. The gain circuit  470  of the LED controller  410  may control the properties of the electromagnetic signal emitted by the LED  405  such that the light detector  420  is maintained slightly below a detection range threshold. By maintaining the light detector  420  within a specific range, the light detector  420  may be controlled such that the reflected signal reaching the detector is below the detectable threshold unless an object  450  is placed within a predetermined distance from the non-contact switch  400 . LED controller  410  may modulate current, voltage or power to LED  405  to maintain the light detector  420  within a specific threshold or operating range as desired by the configuration of distance within which the object  450  may be detected. In some embodiments, gain circuitry may be adjusted so that object  450  is detected at a greater distance. In other embodiments, gain circuitry is adjusted so that the object  450  is detected at a distance very close to the non-contact switch  400 . The distance may be any distance ranging from 1 millimeter, 2 millimeters, 5 millimeters, 1 centimeter, 2 centimeters, 5 centimeters, 10 centimeters, 20 centimeters, 50 centimeters, 70 centimeters, 1 meter, 2 meters, 5 meters, 10 meters, 20 meters or any other distance desired by the user. In some embodiments, LED controller  410  comprises functionality which scales up or scales down the gain of the LED  405  using a dial, a button or a setting. In some embodiments, software operating on a processor of the LED controller  410  monitors and modulates the gain of the light emitted by one or more light sources of the LED  405  to maintain light detector  420  within a specific operating detection range. The gain circuitry of the LED controller  410  may be adjusted in response to background noise to compensate for increased or decreased background noise. 
         [0186]    LED controller  410  may modulate, control or adjust LED  405  operation such that LED  405  emits or generates light of a specific wavelength, power or intensity range as controlled by the LED controller  410 . In a number of embodiments, LED controller  410  modulates, adjusts or controls LED  405  such that LED  405  emits one or more signals of a specific intensity controlled by LED controller  410 . In many embodiments, LED controller  410  modulates, adjusts or controls LED  405  such that LED  405  emits light in pulses occurring at a specific frequency. In some embodiments, LED controller  410  modulates LED  405  to emit light within the infra red wavelength range. In many embodiments, LED  405  emits light within infra-red wavelength range. In a plurality of embodiments, LED  405  emits light having a spectral range of less than 100 nanometers. In many embodiments, LED  405  emits light having a spectral range of less than 50 nanometers. In some embodiments, LED  405  emits light having a spectral range of less than 10 nanometers. In a number of embodiments, LED  405  emits light having a spectral range of about 5 nanometers or less than 5 nanometers. In some embodiments, LED  405  emits light having a spectral range of about one or two nanometers of full width at half maximum of the signal. In a number of embodiments, LED  405  emits light having a spectral range of less than one nanometer. 
         [0187]    LED  405  may include a plurality of light sources, one of which acts as a light source emitting a background noise signal. In some embodiments, a non-contact switch  400  comprises a plurality of LEDs  405 . A first one of the LEDs  405  may emit a pulsed signal designated to be the signal that the light detector  420  detects and interprets. This signal may be the signal to be reflected off of the object  450  and detected by the light detector  420 . The second one of the LEDs  405  may emit a constant low intensity signal, such as a synthetic background noise signal. Synthetic noise may be noise generated by LED  405  to suppress any background noise created by the environment. The synthetic noise signal may be in the general intensity or power range or in an intensity or power range that is larger than the intensity or power range of the background signal of the environment coming from outside of the non-contact switch  400 . The synthetic background noise or background noise signal produced by the second LED  405  may be any signal within a wavelength and power range detectable by the light detector  420 . By having a stronger synthetic constant background noise signal transmitted by one or more LEDs  405 , any additional less intense background noise signals from the environment may be not as damaging to the communications of the LED  405 . In one example, a first LED  405  emits a high intensity signal via which the light switch enclosure  400  detects the presence of the object  450 . The second LED  405  of the same or a different light switch enclosure may emit a lower intensity signal than the signal emitted by the first LED  405 . The second LED  405  signal may have an intensity that is higher than a common or expected background noise from the environment. Both, the first and the second LEDs  405 , may emit signals that are electromagnetic signals within a frequency, power or intensity range that is detected by the light detector  420 . The light detector  420  may detect both signals. As background noise is generated from the environment, the second LED  405  emitting a stronger signal in this wavelength range than the background noise, may in suppress the background noise. In some embodiments, LED  405  comprises a Rohm or Sharp surface mount infrared emitting component, such as for example a Rohm palm device component emitting infrared light at pulses of around 40 kilohertz.

The object  450  may be detected by the detector  420  due to the object  450  reflecting the signal from the LED  405  to the light detector  420 . In such instances, light detector  420  may detect the presence of an object  450  when object  450  is within a specific distance from the light detector  420 .

In some embodiments, object  450  is a person that reflects a signal into the light detector  420  of the non-contact switch  400  by walking into a room that has a light non-contact switch  400  installed on a wall. In some embodiments, LED  405  emits an electromagnetic signal which is reflected off of the person and detected by the light detector  420 . The light detector  420  may detect the presence of the person in the room and send the signal to the detector controller  425  which in turn may send an instruction to lighting devices  110  in the room to turn on and emit light. 
         [0193]    Object  450  may be a device or an apparatus emitting a signal. In some embodiments, object  450  is an emitter such as a remote controller that emits an infra red signal detected by the non-contact switch  400 . The signal may be detected by the light detector  420  and the light from the lighting devices  110  may be turned on. In still further embodiments, object  450  may be any object, person or a device intercepting, reflecting or affecting the signal detected or sensed by the light detector  420 . Object  450  may be any object reflecting a portion of light emitted by LED  405  toward light detector  420 . In some embodiments, object  450  emits an electromagnetic signal, heat, acoustic or sound signal, a wireless signal, radio signal or any type and form of signal that the light detector  420  detects. In some embodiments, object  450  creates an interference or obstruction to an intensity, phase, frequency or amplitude of a signal detected by light detector  420 . Object  450  may create an obstruction or a lapse in the signal amplitude, phase, frequency or intensity, which may be detected by a light detector  420 . In some embodiments, object  450  reflects a signal such that the light detector  420  detects the reflected signal in an increasing fashion as the object  450  approaches the light detector  420 . 
         [0194]    The components of the non-contact switch  400 , such as the LED  405 , LED controller  410 , light detector  420  and the detector controller  425  may each include one or more gain circuits to adjust the amount of light from the LED  405  to be detected by the light detector  410 . In one example, a gain circuit of a LED  405  may adjust and control the output light of the LED  405  to maintain the light detector  420  within a specific operating range. The specific operating range may be a range of operation of the LED  405  or light detector  420  or both such that the light detector  410  detects the light from the LED  405  with a specific sensitivity. For example, the gain circuit may cause the LED  405  to emit just enough light to enable the light detector  420  to barely detect portions of the light from the LED  405  reaching the light detector  410 . The portions of light may be the fraction of light reflected from a transparent or a semi-transparent portion of an enclosure of the non-contact switch  400 , such as a transparent cover. The transparent cover may include glass or a plexiglass portion that reflects the light towards detector  420 . The gain circuit may maintain the amount of light detected by the light detector  420  just below the threshold of the presence of the object  450 . The presence of the object  450  may then provide an additional amount of reflection reaching the light detector  420 , thus exceeding the threshold of detection. Once the threshold is exceeded the light detector  420  may send the signal that object  450  has been detected. 
         [0195]    Similarly in another example, a gain circuit of light detector  420  may adjust and control the detection settings of the light detector  420  to maintain the light detector  420  within a specific operating range. The gain circuit may cause the light detector  420  to detect light with a specific sensitivity or configuration to enable the light detector  420  to detect portions of the light from the LED  405  just below the detection threshold of the light detector  420 . As such, the light detector  420  may detect absence of any object  450  from the perimeter of the non-contact switch  450 . In the instance that the object  450  approaches the non-contact switch  400 , the object  450  will detect an additional amount of the signal from the LED  405  back into the light detector  420 . The gain circuit maintaining the amount of light detected by the light detector  420 , may experience a rising signal which will be too strong to be compensated for by the gain circuit quickly enough and the light detector  410  will detect the presence of the object  450 . Similarly, gain circuits may be deployed in the led controller  410  or detector controller  425  in any orientation. The gain circuits may control the sensitivity of the light detector  420  or the gain circuits may control the intensity, power, pulse frequency, carrier frequency or even wavelength of the light emitted from LED  405  to enable and control the detection of the object  450  when present. 
         [0196]    Non-contact switch  400  may be used by any number of users to control, manage or configure a lighting system  100  as well as to communicate with one or more of lighting system  100  components. Sometimes, light non-contact switch  400  is configured to perform a set of tasks enabling user communication with a lighting system  100 . In some embodiments, non-contact switch  400  is configured or tuned to perform sensing of a user&#39;s presence. In many embodiments, non-contact switch  400  is configured or tuned to enable a user to control light intensity, light color, pulsing or other performance characteristics of light sources  110 . In many embodiments, non-contact switch  400  is configured or tuned to enable a user to select a group of light sources  110  and control them separately from other light sources  100 . In some embodiments, non-contact switch  400  components are tuned and configured to operate based on frequency of pulses of signal at a specific predetermined frequency. In some embodiments, light non-contact switch  400  components are tuned and configured to emit and/or detect pulses of signal at a specific predetermined intensity. In still further embodiments, light non-contact switch  400  components are tuned and configured to emit and/or detect pulses of signal within a specific predetermined spectral range. 
         [0197]    For example, non-contact switch  400  components may be tuned and configured to emit and/or detect the signal at a specific predetermined combination of frequency, intensity, wavelength or modulation. Upon placing an object  450  in the vicinity of the non-contact switch  400  component, any feature of the signal, such as the intensity, frequency, wavelength or format, may be interrupted and the interruption may be detected by the light detector  420 . In some embodiments, LED controller  410  modulates LED  405  to emit or generate pulses or bursts of electromagnetic, acoustic or other wireless signal at a specific frequency and a specific intensity. Light detector  420  may be modulated by detector controller  425  to detect the signals emitted by the LED  405  at the frequency and intensity range emitted by the LED  405 . The detector controller  425  may modulate the light detector  420  by user configuration, frequency or resistance adjustment, programming of the detector controller  425 , setting up configuration inputs or any other user action or activity. Detector controller  425  may process the signals from the light detector  420  in accordance with configuration settings and alert other lighting system  100  components when the object  450  is in the vicinity. In some embodiments, signals emitted by LED  405  may be adjusted to include pulse frequency, signal intensity, signal wavelength and modulation format which are all within detectable range of the light detector  410 . The light detector  410  may continuously, periodically or randomly check for the signal presence. The signal being maintained by the gain circuit within a specific range just below a detectable threshold range of the light detector  410  may signify that the object  450  is not within the vicinity. However, when the object  450  is within the vicinity the signal reflected off of the object  450  and reaching the light detector  410  may increase and exceed the threshold. Light detector  410  may then detect the presence of the object  450 . In some embodiments, object  450  may interrupt or change the intensity, power, frequency, wavelength or modulation of the signal emitted from the LED  405 . Light detector  410  may detect such changes and interpret the detection as the presence of the object  450 . 
         [0198]    The threshold distance or distance range within which the non-contact switch  400  components detect the presence of object  450  may be configured by any configuration method. In some embodiments, the user configures the threshold or distance range by setting the distance or relative position or direction of the non-contact switch  400  components, such as the LED  405  and light detector  420 . In further embodiments, the threshold or distance range may be set by choosing a duration of pulse and the frequency of pulses emitted by LED  405 . In still further embodiments, the threshold or distance range may be set by selecting a spectral range of the light emitted by LED  405 , as well as the average intensity of the light emitted. In other embodiments, lighting system  100  includes a configuration tool which enables the user to configure the vicinity range or threshold within which the object  450  is detected. In some embodiments, the threshold or the range of the vicinity or distance within which the object  450  is detected is preset or preconfigured by the manufacturer. In further embodiments, the threshold range or the distance range of the vicinity may be adjusted by a button, setting, dial or an input on the light switch enclosure  400  or any other lighting system  100  component. 
         [0199]    The vicinity or range within which the object  450  is detected by the non-contact switch  400  may be as any range or threshold of distance. In some embodiments, the vicinity is any length between the object  450  and the non-contact switch  400 . In some embodiments, the vicinity is any distance or range of about 1, 2, 5, 10 or 15 centimeters. In further embodiments, the vicinity is 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 millimeters. In further embodiments, vicinity is a distance of 15, 20, 20, 30, 40 or 50 centimeters. In other embodiments, vicinity is a range or a threshold of distance of between 50 centimeters and 1 meter. In further embodiments, vicinity is a range of between 1 and 10 meters. Vicinity may be configured by configuring or adjusting the output signal characteristics of the LED  405  and detectable range and performance of light detector  420 . In some embodiments, vicinity may be altered by the user using configuration schemes, settings, programs or inputs for the light switch enclosure  400  or lighting system  100 . In many embodiments, vicinity is a range or threshold of distance which is constant and predetermined for a specific non-contact switch  400 . In other embodiments, vicinity is a range or threshold of distance which may vary depending on the configuration, user inputs and signals or instructions from other lighting system  100  components. 
         [0200]    Non-contact switch  400  may communicate to other lighting system  100  components by sending or receiving signals or instructions. In some embodiments, LED  405  of a first light switch enclosure transmits communication to a second light switch enclosure  400 . The light detector  420  of the second light switch enclosure  400  may detect the signal emitted by the LED  405  of the first light switch enclosure  400 . The second light switch enclosure  400  may process or forward the instruction  650  to one or more lighting devices  110 . In some embodiments, both the first and the second enclosures  650  are associated with one or more lighting devices  110 . When a first light switch enclosure  400  transmits a transmission, such as an instruction  650  via LED  405 , the second light switch enclosure  400  may receive the transmission and forward it to the one or more lighting devices  110  associated with the second light switch enclosure  400 . The one or more lighting devices  110  may implement the instruction  650  or operate in accordance to the instructions received. In some embodiments, a plurality of light switch enclosures  400  are configured to be in communication with one or more lighting devices  110 . The master lighting device  110  may transmit an instruction  650  to any number of the plurality of lighting devices  110  via it&#39;s own non-contact switch  400 . The signal, such as the instruction  650 , may be transmitted wirelessly via the LED  405  and the plurality of light switch enclosures  400  may receive the instruction  650  and forward the instructions  650  to the lighting devices  110  to implement the instruction  650 . 
         [0201]    Non-contact switch  400  may further communicate with one or more light sources  110 . In some embodiments, components of the non-contact switch  400  may be associated with one or more light sources  110 . For example, a light source  110  may comprise components of the non-contact switch  400 , such as the LED  405  or the light detector  420 . Non-contact switches  400  may be used for assigning of unique digital addresses to one or more lighting system  100  components. In some embodiments, a non-contact switch  400  is used to assign a unique digital address to a lighting device  110  that is connected to a switch  400 . In further embodiments, a non-contact switch  400  is used to assign a unique digital address to a plurality of lighting devices  110  that are connected to or in communication with the light switch enclosure  400 . Assigning of the unique digital address may be done by sending an instruction or a command via connections  105  to all the lighting devices  110  connected. The instruction or the command may be any instruction  650  that indicates that a lighting device  110  will be assigned an unique digital address. The same or another instruction may be transmitted identifying a first unique digital address, or the first address  127  to all the lighting devices  110 . A user may place a hand, or any other object  450 , within the vicinity of a switch  400  associated with a particular lighting device  110 . The light detector  420  of the light switch enclosure  400  may detect the presence of the hand and send the signal to the lighting device  110  associated with the light switch enclosure  400 . The receipt of the signal by the lighting device  110  will indicate to the lighting device  110  that the user has identified that particular lighting device  110  as the lighting device  110  to be assigned the first address  127 . This particular lighting device  110  may then save the address  127  and use the address  127  for communicating with any other lighting devices  110  on the network of lighting devices  110 . In such or similar manner the user may identify other lighting devices  110  and assign to them any particular unique digital addresses or addresses  127 . The user may also assign to a group of lighting devices  110  one address  127 , such that entire group will behave and act in accordance with instructions or commands transmitted along with that particular address  127 . 
         [0202]    Non-contact switch  400  may be used for assigning a master or slave status to any lighting device  110 . In some embodiments, the user may select a master or slave status by placing a hand in the vicinity of the light switch enclosures  400  associated with particular lighting devices  110 . A component of a lighting system  100  may receive an instruction or a signal that the lighting system  110  is placed into an assignment mode. An assignment mode may be any mode of operation of the lighting system  100  wherein the lighting system  100  assigns an addresses  127  or a status, such as slave or master status, to one or more lighting system  100  components. In some embodiments, an assignment mode is a mode, a function, a feature of a lighting system  100  to assign an addresses  127  to any lighting system  100  component. In other embodiments, an assignment mode is a mode, a function, a feature of a lighting system  100  to assign an master or a slave status to any lighting system  100  component. In yet further embodiments, an assignment mode is a mode, a function, a feature of a lighting system  100  to assign any number of lighting devices to a group. Assignment mode may be a mode of operation or configuration in which the lighting system  100  allows the user to select via non-contact switch  400  associated with light sources  110  the light sources  110  will be assigned to specific statuses, specific groups or specific addresses  127 . When the lighting system  100  is placed in the assignment mode, the lighting system may send a group assigning instruction to each lighting device  110 . The user may select via non-contact switch  400  which of the lighting devices will be assigned to this particular group. Following the selection, the user may exit the assignment mode and each selected light source  110  may be saved into the group as selected. Similarly, the user may assign addresses  127  or master and slave statuses to each of the lighting devices  110 . 
         [0203]    Assignment mode, implemented by a non-contact switch  400 , may be any function or a setting of any of the lighting system  100  components, such as a function, a feature or a setting implemented by any of a controller  120 , a communicator  125 , a master/slave addressor  130 , a power supply  140  or a light source  110 . Assignment mode may include a software, a hardware or a combination of software and hardware for implementing tasks relating to assignment of addresses  127  for each of the lighting system  100  components. Assignment mode may include a means for transmitting or receiving messages from each of the lighting system  100  components who have received and accepted the addresses  127 . Assignment mode may further receive confirmation messages from the lighting devices  110  that were selected by the user via non-contact switch  400 . In some embodiments, lighting system  100  components store the address  127  received from the master and transmit the confirmation messages to the master lighting device  110 . The master lighting device  110  may then be aware which lighting devices have accepted and saved the address  127  the user has selected. The master lighting device  127  may send any further communication of these devices using the addresses  127  assigned. In some embodiments, the master lighting device  110  transmits one of a plurality of addresses  127  to each of the lighting system  100  components and waits for the lighting system  100  components to accept the address  127  transmitted. The lighting system  100  components may accept the address  127  upon receiving the signal from a non-contact switch  400  as selected by the user. Those lighting system  100  components selected by the user may return to the master lighting device  110  the confirmation messages indicating that these lighting system  100  component have accepted the addresses  127 . Similarly, the master lighting device  110  may send out group assignment signals to the lighting devices  110  in the network. The lighting devices  110  may, upon receiving signals from the non-contact switch  400  that an object  450  was detected, send to the master lighting device the confirmation signals that the user has selected these lighting devices  110  to be in the same group. The group may be assigned a special group address  127 , or a group identifier. Such a group address or a group identifier may be used to control the group of lighting devices  110  selected by the user in the future. In one example, light source  110 A accepting address  127 A previously sent by the master receives a signal from a light switch enclosure that a user&#39;s presence, or an object  450 , was detected. The light source  110 A sends a confirmation message confirming that light source  110 A has accepted the address  127 . The master lighting device  110 , in response to the received confirmation message, associates address  127  with the lighting system  100  component for any future communication. In some embodiments, assignment mode entails the master receiving messages from one or more lighting system  100  components and assigning addresses  127  in response to the received messages. 
         [0204]    In one example, a non-contact switch  400  may be utilized with associated lighting system  100  components for assignment of addresses  127 . In some embodiments, a master communicates with a plurality of lighting system  100  components which may or may not have a master status. One of the plurality of lighting system  100  components is a light source  110 A. In a number of embodiments, lighting system  100  components send information to the master using non-contact switch  400  associated with lighting system  100  components. A master may be placed in an assignment mode and may be available to receive any information from any one or more of lighting system  100  components. A user may select a light source  110 A by placing an object  450 , such as a hand, in front of a non-contact switch  400  associated with the light source  110 A. Light detector  420  of the non-contact switch  400 , in response to the placed object  450 , detects light emitted by LED  405  and non-contact switch  400  sends a signal indicating that the light source  110 A is selected. Light source  110 A transmits a signal to the master indicating the user&#39;s selection and the master assigns an address  127 , such as address  127 A, to light source  110 A. The master transmits information notifying light source  110 A of the new address  127  assigned to the light source  110 A. The light source  110 A uses the assigned address  127  to receive for communication with master or any other lighting system  100  component. In some embodiments, light source  110 A uses the assigned address  127  to recognize which information transmitted by any other lighting system  100  component is addressed to light source  110 A. 
         [0205]    In a similar example, the user may proceed to select any number of lighting system  100  components by placing an object  450  in front of a non-contact switch  400  associated of each selected lighting system  100  component. The master, in response to user&#39;s selections via a non-contact switch  400 , may assign an address  127  to each of the user selected lighting  100  system components. Upon completing all the selections, the user may terminate the assignment mode and the master may store all the addresses  127  and lighting system  100  components associated with each of the addresses  127 . The lighting system  100  components may use addresses  127  assigned to transmit or receive information or communication among the lighting system  100  components assigned. In some embodiments, similar methods may be used to create a group of lighting system  100  components, or a group of light sources  100 . A user may configure the group by selecting via non-contact switch  400  the light sources  110  that are the members of the group. In further embodiments, non-contact switch  400  may be used to distinguish a group of light sources  110  from another group of light sources  110 . In some embodiments, each of the groups selected may be controlled separately by the lighting system  100 . Each lighting system  100  component may store an addresses  127  of the group or a zone. As the commands or instructions are received for the light sources  110  of the specific group, the address  127  may be used as a key to address the members of the specific group to perform a certain function without affecting light sources  110  of other groups. Such addresses may also be referred to as group identifiers. Non-contact switch  400  may be used in any combination with any other lighting system  100  component to select, set up or configure any number of lighting system  100  components. 
         [0206]    Referring now to  FIG. 5B , an embodiment of steps of a method for detecting an object is depicted. At step  505 , an LED of a device emits a signal. At step  510 , a first portion of the signal reflects off of a transparent cover towards a detector of the device and a second portion of the signal propagates through the transparent cover. At step  515 , a gain circuit maintains a predetermined operation of the detector. At step  520 , the detector determines that a reflected first portion of the signal is below a threshold of the detector. At step  525 , the second portion of the signal reflects off of an object outside of the device towards the detector of the device. At step  530 , the device determines that the object is present responsive to the detector determining that the reflected first and second portions of the signal exceed the threshold of the detector. 
         [0207]    Further referring to step  505  of  FIG. 5B , a LED of a device emits a signal. The signal emitted may be any signal, such has an electromagnetic signal. In some embodiments, the signal is an infrared signal or a radio signal. In further embodiments, the signal is a modulated signal comprising a carrier frequency between 20 and 60 kilohertz, such as 40 kilohertz for example. The carrier frequency may be a frequency of pulses of bursts of light emitted by the LED. The signal may further be amplitude, frequency, phase or pulse width modulated. In some embodiments, the signal may further be modulated in any additional way. In some embodiments, the signal comprises high components of the signal and low components of the signal. In some embodiments, high components of the signal correspond to pulses of light emitted from the LED. In further embodiments, low components of the signal correspond to durations of time when there are no pulses of the signal. In still further embodiments, low components of the signal correspond to durations of time where LED emits light having a lower intensity than the intensity of light emitted during the emission of high components of the signal. The high components of the signal may comprise or correspond to portions of the signal comprising voltage, current, power or intensity that is higher or larger than the voltage, current, power or intensity of the portions of the signal that are comprised by, or correspond to, the low components. The signal may comprise portions of the signal comprising any number of pulses such as 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 80, 90 or 100 pulses for example. In some embodiments, the portions of the signal comprise more than 100 pulses, such as 200, 500 or 1000 pulses. Each pulse may be a part of a period comprising high and low components. In some embodiments, a pulse may comprise any number of periods comprising high and low components. In further embodiments, a pulse comprises a high component and a duration of signal not having a pulse comprises a low component. The signal may be emitted within any conical angle from the LED, such as 180 degrees, for example. The signal may be emitted from within an enclosure of the device. The signal may comprise any type and form of communication comprising instructions, commands or data. The signal may comprise communication for any component of the lighting system  100 , such as for example a lighting device  100  or another non-contact switch  400 . 
         [0208]    At step  510 , a transparent cover of the device reflects a first portion of the signal and allows a second portion of the signal to propagate through or transmit through the transparent cover. In some embodiments, the first portion is emitted by a first light source of the LED  405  and the second portion is emitted by a second light source of the LED  405 . In further embodiments, the first and the second portions are emitted by the same light source of the LED  405 . In other embodiments, the first and second portions of the signal are emitted by different light sources of the LED  405 . In still further embodiments, some portions of the first or second portions of the signal are emitted by multiple light sources of the LED  405 , which may be same or different light sources. In some embodiments, the signal may be reflected from components, such as enclosure of the device, led controller  410 , power supply  140 , light detector  420 , detector controller  425 , connections  105  or any other component of the non-contact switch  400 . In some embodiments, a first portion of the signal is reflected off of the transparent cover  460 . A portion of the first portion of the signal may be reflected towards a light detector, such as the light detector  420 . In some embodiments, the second portion of the signal propagates through the transparent cover and exit the non-contact switch  400 . The transparent cover may reflect a percentage of the signal, such as 2, 4, 6, 8 or 10 percent and propagate the remainder of the signal. 
         [0209]    At step  520 , a gain circuit maintains, monitors, controls or adjusts operation of the detector. Gain circuit may be gain circuit  470 . The detector may be light detector  420 . Gain circuit may maintain operation of the detector to ensure that the detector operates within a predetermined sensitivity range. In some embodiments, predetermined sensitivity range may be an average intensity range of the detector that is below the threshold for detecting a presence of an object  450 . In some embodiments, specific sensitivity range may be an average intensity range of the light detected that is above the detection threshold for detecting a presence of an object  450 . In other embodiments, specific sensitivity range may be an average intensity range of the light detected that includes a detection threshold for detecting a presence of an object  450 . In some embodiments, specific sensitivity range may be an intensity or power range of the detector that is below the detection threshold for detecting of the presence of the object  450 . Gain circuit may maintain operation of the detector a specific percentage of the detection threshold intensity or power for detecting the presence of the object  450 . In some embodiments, gain circuit maintains operation of the detector between below the detection threshold for detecting the object  450  by a predetermined percentage of the threshold. The predetermined percentage of the threshold may be any percentage of the intensity or power of light detected to meet or exceed the threshold for detecting of the object  450 . In some embodiments, the predetermined percentage of the threshold may be between 0 and 5 percent, 5 and 10 percent, 10 and 20 percent, 20 and 30, 30 and 40 percent, 40 and 50, 50 and 60 percent, 60 and 70 percent, 70 and 80 percent, 80 and 90 percent, 90 and 95 percent, or 95 and 100 percent of the detection threshold. In some embodiments, the gain circuit determines that the signal or a portion of the signal detected by the detector is below the specific sensitivity range. The portion of the signal may be a duration of any number of pulses, such as between 1 and 10 pulses, 10 and 20 pulses, 20 and 30 pulses, 30 and 40 pulses, 40 and 50 pulses, 50 and 60 pulses, 60 and 80 pulses, 80 and 100 pulses, 100 and 200 pulses, 200 and 2000 pulses or any other number of pulses. In some embodiments, the gain circuit determines that a portion of the signal comprising any number of high components and low components is below the specific sensitivity range. The gain circuit may adjust or increase the gain to ensure that the detector detects the portion of the signal within the specific sensitivity range or within a specific percentage range of the detection threshold. Similarly, the gain circuit may determine that a portion of the signal comprising any number of high components and low components is above the specific sensitivity range. The gain circuit may adjust or decrease the gain to ensure that the detector detects the portion of the signal within the specific sensitivity range or within a specific percentage range of the detection threshold. Adjustment of gain may be done by varying pulse width of the signal. In some embodiments, adjustment of gain is implemented by increasing or decreasing a duration high components of each pulse. In further embodiments, adjustment is implemented by increasing or decreasing a duration of low components of each pulse. By adjusting the high component to low component duration ratio of the pulses of the signal the device may adjust the gain of the detector. Adjustment of gain may be done at a specific rate to allow the gain not to be adjusted fast enough in embodiments when object  450  approaches the device. In such instances, the object  450  may cause the portion of the signal detected to exceed the detection threshold of the detector faster than the gain circuit would adjust the gain of the signal. 
         [0210]    At step  520 , the detector determines that a reflected first portion of the signal is below a threshold of the detector. The threshold of the detector may be a sufficient the power or intensity of signal detected by the detector to recognize the presence of the object  450 . In some embodiments, the reflected first portion of the signal includes the portion of the signal reflected by the transparent cover  460 . In further embodiments, the reflected portion of the signal includes the portions of the signal reflected by any segment or component of the non-contact switch  400 . In still further embodiments, detector determines that the total signal reaching the detector is below the threshold, in response to actions, adjustments or maintaining of performance performed by the gain circuit. 
         [0211]    At step  525 , the second portion of the signal reflects off of an object outside of the device. The second portion of the signal may comprise a portion of the signal that has propagated through the transparent cover. The second portion of the signal may comprise a portion of the signal that has propagated through the transparent cover and has reflected off of an object, such as an object  450 . In some embodiments, the second portion of the signal or a portion of the second portion of the signal reflects towards detector, such as the light detector  420 . In further embodiments, the second portion of the signal or a portion of the second portion of the signal reflects off the object and through the transparent cover towards the detector. The object may be a portion of a body of a person, such as a user, or any embodiment of the object  450 . 
         [0212]    At step  530 , the device determines that the object is present responsive to the detector determining that the reflected first and second portions of the signal exceed the threshold of the detector. In some embodiments, the detector determines that the reflected first and second portions of the signal exceed the threshold of the detector. In some embodiments, the detector receives the reflected second portion of the signal reflected off of the object  450  in addition to the received first portion of the signal. The detector may detect the sum of the reflected first and second portions of the signal. In some embodiments, the detector detects average intensity or power of the reflected first and second portions of the signal. In further embodiments, the detector determines that the sum of the received first and second portions of the signal exceeds the threshold intensity or power needed for the detector to recognize the presence of the object  450 . In still further embodiments, the device determines that the object is present responsive to the determination of the detector that the reflected first and second portions of the signal exceed the intensity or power threshold of the detector needed to detect the presence of the object. In still further embodiments, the determination that the object is present is responsive to the actions or adjustments by the gain circuit. In still further embodiments, the determination that the reflected first and second portions of the signal exceed the threshold is further based on the average intensity of the plurality of pulses of the reflected first and second portions of signal exceeding the threshold established by the gain circuit.

         [0225]    Connection  105 , which may also be referred to as the line, may be any medium through which signals, communications, instructions, power and intensity are transmitted. In some embodiments, the line is a I2Systems Lightlink™ of I2Systems Inc. In further embodiments, the line is I2Systems or I2System Lightlink Control Bus, also referred to as LLCB by I2Systems Inc. The line may comprise a single active wire connection between two or more lighting devices  110  and a single ground return wire. Two or more lighting devices  110  may be connected via the line in parallel connection, in series connection or in any combination of parallel and series connections. In some embodiments, the lighting devices are connected in a parallel connection pattern in which the communication receiving pins of the lighting devices  110  are connected to the active wire of the line and ground pins of the lighting devices  110  are connected to the ground wire of the line. In some embodiments, the line includes a medium for controlling lighting devices  110  via a lighting dimmer scheme, such as a DMX-512 protocol for a DMX connection.

The line may include an active wire via which the communications are transmitted, and a ground return wire. Communications transmitted may include signals, instructions, request and response messages, power or intensity modulating signals, commands, configurations, settings, read-backs or any other type and form of transmissions. The communications may be digital transmissions of any voltage or current characteristics or range. In some embodiments, digital pulse width modulated (PWM) signals based on a 5 volt digital logic are transmitted via the line. The PWM signals may use a 5 volt signal to indicate a high state, while a 0 volt transmission may indicate a low state. A threshold distinguishing between the high and the low levels may be any value between 0 and 5 volts, such as 2.5 volts for example. In some embodiments, the signal in addition to only two levels, a high level and a low level, may further include additional levels, such as a third level, a fourth level, a fifth level, and so on. The line may transmit communication using a half-duplex channel allowing a single lighting device  110   a  to send a communication at one time. The lighting devices  110  receiving the communication may send acknowledgement transmissions in response to the received communication. The acknowledgement may include a response that a received instruction  650  was implemented or an indication that the received communication was acknowledged. In some embodiments, acknowledgements include a response that an error occurred or that that the received instruction  650  was not acknowledged. For example, the master lighting device  110   a  may send an instruction  650  to set a first slave lighting device  110   b  as a master lighting device. In response to the received instruction  650 , the master lighting device  110   a  may receive acknowledgements from each of the lighting devices  110 . Once each of the lighting devices  110  has acknowledged affirmatively, the first slave lighting device  110   b  may be assigned a master status and all the remaining lighting devices  110 , including the master lighting device  110   a , may be assigned a slave status. The first slave lighting device  110   b  is from that point on recognized as the master and may send any instructions  650  or commands to any of the lighting devices  110 . Thus, the group of lighting devices  110  in this embodiment only have a single master lighting device  110  at a given time. 
         [0227]    Instructions and acknowledgements transmitted between the lighting devices  110  may be sent via the line using any communication, such as DMX communication that uses DMX-512 protocol. In some embodiments, the DMX communication may be used or modified to enable two-way communication between lighting devices  110  by using RS-232 connections to listen for incoming communication, such as instructions or acknowledgements. Instructions or commands may be of any bit length, such as 2 bits, 4 bits, 8 bits, 16 bits or 32 bits. In some embodiments, instructions include a command of 4 bits, 8 bits of data and 4 bit checksum. In further embodiments, an additional instruction may be used to check for activity over the line. The rate of the communication transmitted via the line may vary. In some embodiments, communication is transmitted via the line at a rate of 250 cps. In further embodiments, communication transmitted may be at speed of 500 cps or clocks per second, 1000 cps, 4000 cps, 16000 cps or any other rate. 
         [0228]    Referring now to  FIG. 6B , an embodiment of steps for a method for assigning a status to a lighting device over a single line or a connection used by the lighting device to communicate with one or more of other lighting devices is illustrated. At step  605 , a first lighting device receives via a line a signal comprising an instruction within a first duty cycle. At step  610 , a detector of the first lighting device detects the instruction. At step  615 , a master/slave addressor assigns a status identified by the instruction to the first lighting device. At step  620 , the first lighting device emits light identified by the first duty cycle. At step  625 , the first lighting device receives via the line a second signal comprising a second duty cycle. At step  630 , the detector detects that the second signal comprises no instruction and the first lighting device emits light identified by the second duty cycle. 
         [0229]    At step  605 , a first lighting device, such as the lighting device  110 , receives via a line a signal comprising an instruction within a first duty cycle. The first lighting device may receive the signal via any line, such as a connection  105  for example. In some embodiments, the signal is transmitted to the first lighting device via a conducting wire. In further embodiments, the first lighting device receives the signal via a wireless link. In yet further embodiments, the first lighting device receives the signal in the form of an electromagnetic wireless transmission that can be of any bandwidth or spectral range. In still further embodiments, the first lighting device receives the signal via an optical fiber or via any type and form of a waveguide. The signal received may include any type and form of a communication or a transmission, such as digital, analog, optical, wireless, electromagnetic or electrical signal or transmission. The signal may be divided into any number of periods  205 . In some embodiments, the signal is of a duration of a single period  205 . In other embodiments, the signal is of a duration of a plurality of periods  205 . The signal may include any number of instructions, such as the instructions  650 . In some embodiments, the instruction includes an instruction  650  to set or establish a status of the first lighting device.

       G. Active Thermal Management Via Profile Curves 
       [0235]    Referring now to  FIGS. 7A-7C , embodiments of systems and methods for active thermal management (ATM) techniques of the present solution will be described. As a brief introduction, a lighting device may comprise one or more components for protecting the lighting device and ensuring that the lighting device operates as long as possible and as efficiently as possible. In one aspect, the lighting device may comprise an active thermal management (ATM) device for monitoring the temperature of the lighting device and adjusting the intensity of the light emitted from the lighting device based on the temperature measured. As the lighting devices deployed in various environments may be exposed to temperatures in which they may overheat and thus have a reduced lifetime, the ATM device may monitor the temperature of the lighting device in order to reduce the temperature as necessary to preserve the lighting device. Alleviating the temperature by reducing the intensity of the light emitted, the lighting device may prolong the lifetime of the lighting unit of the lighting device by reducing the intensity of the light emitted and thus alleviating the device and prolonging its life. 
         [0236]    Referring now to  FIG. 7A , an embodiment of a lighting device with ATM is depicted. The lighting device  110  may include a light source, such as LED  405 , driven or controlled by a driver or controller, such as LED controller  410 . A lighting device  110  may comprise an active thermal management (ATM) device  710  for adjusting brightness and intensity of light based on the temperature of the lighting device. The ATM may include a temperature measuring component  715  and a processor  720  for executing a function or equation  725  for adjusting an incoming signal to an adjusted signal. Responsive to profile curves  730 , the processor may also determine the adjusted signal based on the incoming signal and temperature. 
         [0237]    In further details, an ATM device  710  may be attached to a lighting device, comprised within a lighting device or be external to the lighting device. Embodiments of the ATM device may be referred to as device or ATM. The ATM device may comprise hardware, software or a combination of hardware and software for monitoring lighting device temperature and adjusting brightness or intensity of the lighting device responsive to the temperature. The ATM device may comprise memory and storage for storing information, processor  720 , processing units and logic units, logical circuitry as well as analog and digital circuitry for implementing any functionality described herein. The ATM device may comprise functionality to intercept or monitor incoming signals having instructions to instruct the lighting device to emit at a commanded intensity. The ATM device may comprise functionality to intercept the incoming intensity commands from a PWM signal and modify the commands or the signal (e.g., adjusted signal) to achieve the intensity of light needed to modify the temperature of the device. 
         [0238]    The ATM device may comprise a temperature measuring component  715 . In some embodiments, the ATM device may include a processor or microprocessor having a temperature measurement component. The temperature measurement component may comprise a dual diode, a thermometer, a heat sensor or any other electronic or mechanical temperature measuring device. The ATM and/or temperature measuring component may be designed and constructed and/or attached to measure the ambient temperature within lighting device. The ATM and/or temperature measuring component may be designed and constructed and/or attached to measure the temperature of the lighting device. The ATM and/or temperature measuring component may be designed and constructed and/or attached to measure the temperature of the enclosure of the lighting device. The ATM and/or temperature measuring component may be designed and constructed and/or attached to measure the temperature of the ATM device itself. The ATM and/or temperature measuring component may be designed and constructed and/or attached to measure the temperature of the light source  405 . 
         [0239]    The ATM and/or temperature measuring component may be designed and constructed and/or attached to predict, estimate or extrapolate the temperature of an LED based on the ambient temperature. The ATM may apply factors and/or equations to take a reading of the ambient temperature within the light device and generate an estimated or predicted temperature of the LED. For example, the ATM may increase the ambient temperature by a predetermined factor, such as by addition or multiplication, to arrive at an estimated or predicted temperature of the LED. 
         [0240]    ATM device may use the temperature measurement component to monitor the temperature periodically. ATM may use the temperature measurement component to establish how hot or cool the temperature under measurement is getting. ATM device may comprise functionality for reducing the intensity of the lighting device when the lighting device temperature gets substantially hot, such as greater than a predetermined threshold. In some embodiments, ATM device may operate based on thresholds, thus setting temperature of the lighting device based on temperature thresholds measured. 
         [0241]    In some embodiments, ATM device comprises functionality for adjusting the intensity of the lighting device proportionally to the temperature. ATM device may implement such proportional adjustment based on a mathematical equation  725 . In some embodiments, ATM device may determine a new light intensity level based on a temperature reading and a mathematical equation  725 . For example, ATM device may continuously read the temperature of the lighting device and use a processing unit to calculate the new intensity of light value utilizing a mathematical function or a formula and the value of the measured temperature. In some embodiments, ATM device may determine a new light intensity level based on a temperature reading and the incoming signal with a mathematical equation  725 . In some embodiments, ATM device may determine a new light intensity level by using a temperature reading and an intensity value from incoming signal as inputs into a mathematical equation  725 . 
         [0242]    In other embodiments, ATM device may determine a new light intensity based on a chart  730  comprising the value for the new light intensity setting for each temperature reading. In one embodiment, ATM device determines a temperature of the lighting device by using tables and charts comprising temperature and intensity values to determine the new intensity of light value. A table or a chart may be stored in a memory or storage of a device and may comprise values of all temperatures of the lighting device and their corresponding intensity of light values. The chart or the table may reflect a relationship between the temperature and the intensity of light based on a mathematical equation. ATM device may read the values from the chart or table and match a value of the determined temperature of the lighting device to a temperature value in the table. ATM device may then identify a value for the intensity of light that corresponds to the matched temperature value. As the table may comprise temperature intensity value pairs, the ATM device may use this new identified intensity of light corresponding to the temperature value and set the brightness or the intensity of the device as the intensity value to which the lighting device will be set. Therefore, in some embodiments, the mathematical function may be used either for determining the new intensity value in real time or it may be implemented in a table form for each of the intensity and temperature values so that the ATM device may access the values as appropriate. 
         [0243]    The ATM device may include any type and form of processor  720 , such as a microprocessor. Via the processor, the ATM may execute one or more ATM functions  725  to determine a new intensity or adjusted signal based on both the incoming signal/intensity level and temperature read by or based on the temperature measured by the temperature measuring component. In some embodiments, the ATM function or equation  725  for determining a new intensity level, or a new dim level is: 
         [0000]      New DIM_level=Original DIM_level*((temperature_comp*(256−Original DIM_level)/256)+(256−temperature_comp))/256.
 
         [0000]    In such an equation, the ‘temperature_comp’ may be any number, such as a number between 0 to 9, where 9 represents the highest temperature compensation and 0 represents the lowest temperature compensation. Original DIM_level may represent a number between 0 to 255 corresponding to the level intensity where 0 is the lowest intensity and 255 is the highest intensity. The output may correspond to the New DIM_Level, which may be the new level intensity which has been adjusted to address the temperature factor. ATM device may pick the variables, such as the temperature_comp based on the temperature range measured. For example, if ATM measures the temperature of the lighting device to be within a specific range, the ATM device may pick 1 as the temperature_comp. In other embodiments, if ATM device measures the temperature to be within a different range, the ATM device may pick 3 as the temperature_comp. In some embodiments, instead of being divided between 0 and 9, temperature_comp may correspond to numbers within any number range, such as 0-255 or any other number range used in the arts. In addition, temperature_comp may not only be integer numbers, but may rather be fractional numbers, float numbers with any number of decimal numbers. 
         [0244]    In some embodiments, the ATM function  725  may implement, use or comprise one or more profile curves. A profile curve may comprise a chart or map having an input intensity level on one axis and output intensity level on another axis to obtain a new intensity level based on the input intensity level. A profile curve may be selected based on a temperature, power and/or other operational condition of the lighting device. A profile curve may comprise a chart or map having an input intensity level on one axis and temperatures on another axis to obtain a new intensity level based on the input intensity level and input temperature. The profile curve(s) may be stored in storage, such a in a file, table or database, and accessed by the processor. The profile curve(s) may be stored in memory and accessed by the processor. The profile curves may be represented by data and/or executable instructions accessed and/or executed by the processor. In some embodiments, the ATM function is an implementation of a profile curve. In some embodiments, the ATM function accesses and uses a profile curve. 
         [0245]    Referring now to  FIG. 7B , an embodiment of a chart illustrating different intensity curves for different temperatures. As shown by the illustration, intensity curves of lighting devices that are operating at a high temperature are more curved in contrast to the intensity curves of lighting devices operating at a lower temperature. The mathematical function used to determine the new light intensity value may be any function, such as a logarithmic function, a binomial functional, a trinomial function, or any nonlinear function. In some embodiments, the mathematical function may be used to slide the entire intensity curve over the entire intensity range based on the inverse square law. The inverse square law function may be used to scale all the other values based on the new maximum. The function may affect the higher intensity side more than the low intensity side. 
         [0246]    The profile curves  730  may comprise a non-linear relationship between input intensity and output intensity. In some embodiments, a different profile curve with a different non-linear relationship may be used based on the temperature and/or power level. For example, for one range of temperatures, a first profile curve may be used while for another range of temperatures a second profile curve may be used. In another example, for one range of input intensity levels, a first profile curve may be used while for another range of input intensity levels a second profile curve may be used.

The ATM device may obtain the temperature or measure the temperature responsive to receipt of the incoming signal. The ATM device may obtain the temperature or measure the temperature on a predetermined frequency, such as responsive to a timer. The ATM device may obtain the temperature or measure the temperature on a continuous basis. 
         [0250]    The ATM device may scale, interpret, extrapolate or otherwise adjust the temperature measurement to provide an adjusted temperature measurement that is used for the functions and operations described herein. The ATM device may interpret, estimate from or extrapolate the temperature measurement of one item or entity such as ambient temperature, to provide a temperature measurement for a second item or entity, such as a light source, that is used for the functions and operations described herein. For example, based on the temperature reading of the ambient temperature or the enclosure, the ATM device may determine an estimated temperature of the LED of the light source. 
         [0251]    At step  765 , the ATM device applies an ATM function  725  and/or responsive to a profile curve  730  determines a new intensity level.

The ATM device may determine the second intensity from the function comprising a non-linear relationship between the incoming or input signal and the adjusted or second signal. The ATM device may determine the second intensity from the function comprising a temperature compensation factor applied to a dimming level of the incoming intensity. 
         [0252]    At step  770 , the ATM device provides or outputs a new or adjusted signal for input to the lighting source. The output signal from the ATM device may be used as the input or incoming signal to the light source. The output signal from the ATM device may be used as the input or incoming signal to the controller or driver of the light source.
