     FIELD OF THE INVENTION 
     The present application is generally related to lighting systems. In particular, the present application is directed to systems and methods for assigning a status to a lighting device within a network of lighting devices. 
     BACKGROUND 
     Lighting systems are used in a variety of settings and applications. Many lighting systems traditionally comprise light sources or lighting devices having only limited control and functionality. Such lighting systems are often controlled only by on and off switches or switches that may control the level of lighting. Furthermore, one lighting device may be connected to another lighting device via simple connections between them. A traditional lighting system may include a group of lighting devices connected to the same power or intensity control but without intelligence to control behavior between them. Some intelligent lighting systems do offer more control but are often more expensive due to their complexity in design and increased number of components.

In many embodiments, duty cycle of period  205  signifies or defines intensity light source  110  should emit light with. In a number of embodiments, light source  110 B with a master status transmits information to light source  110 A with a slave status, wherein duty cycle of period  205  of the transmitted information signal, signifies or defines intensity instructions for light source  110 A.

Light source  110 A, in a number of embodiments, in response to the duty cycle of period  205  of the transmitted information signal maintains or remains unchanged intensity of the light emitted. In many embodiments, duty cycle of a signal or an information is related to the intensity of the light to be emitted by a light source  110  receiving the signal or the information. In a plurality of embodiments, duty cycle of a signal or an information is proportional to the intensity of the light to be emitted by a light source  110  receiving the signal or the information.

     C. Status Assignment of Lighting System Components 
     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. 
     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. 
     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 . 
     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. 
     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. 
     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. 
     D. Lighting System Intensity Control with Digital Patterning 
     In addition to previously discussed embodiments,  FIG. 2A  and  FIG. 2B  also include applications relating control of intensity of light sources  110  using digital patterns.

     In a number of embodiments, LED  405  emits light having pulses occurring at a specific frequency and a specific light intensity which, in combination, are at the detection threshold point of light detector  420 . In various embodiments, LED  405  emits light having pulses occurring at a frequency and each of the pulses having a duty cycle which, in combination, are at the detection threshold point of light detector  420 . Sometimes, changing either the frequency of the pulses or the duty cycle of the pulses makes the optical signal emitted by LED  405  detectable or not detectable by the light detector  420 . In many embodiments, LED  405  emits light at pulses of specific frequency, at a specific intensity and within a specific wavelength range, which in combination, produce a light signal which is at the detection threshold point of light detector  420 . Detection threshold any combination pulse frequency, light intensity per pulse and a wavelength range of light signal emitted by LED  405  which borders the range of light signals detectable by light detector  420  and the range of light signals not detectable by light detector  420 .

In some embodiments, a lighting system component within the light switch enclosure  400  comprises any one of or a combination of a circuit, a unit, an algorithm or a function which adjusts the detection threshold point in response to the background infrared radiation or signal. 
     Sometimes, light switch enclosure  400  comprises an LED  405  emitting an infrared optical signal at a constant pulse frequency of between 20 and 50 kilohertz. Sometimes, the infrared optical signal has a constant wavelength or a wavelength range. In some embodiments, the infrared optical signal has a duty cycle for each pulse which is optimized to bring the light switch enclosure  400  at a detection threshold point. In some embodiments, making a duty cycle shorter makes the infrared optical signal detectable by the light detector  420 . In some embodiments, making a duty cycle longer makes the infrared optical signal detectable by the light detector  420 . In a plurality of embodiments, a duty cycle of the infrared optical signal is set so the light detector  420  cannot detect the optical signal unless object  450  is in the vicinity of the light switch  400  enclosure. Upon bringing the object  450  in the vicinity of the light switch  400  enclosure, in such embodiments, the object  450  affects the light detected by the light detector  420 , and the light detector  420  detects the light emitted by LED  405 .

Sometimes, lighting system  100  background environment creates background noise, such as infrared noise crated by lights, or heat sources. In a number of embodiments, the light emitted by the second LED  405  has a higher intensity than the background noise. In many embodiments, the second LED  405  creates a synthetic background radiation of a higher intensity than the background noise. In some embodiments, a second LED  405  emits a constant low intensity light which is lower than the intensity of pulses emitted by a first LED  405  but higher intensity than the background noise. The second LED  405 , in some embodiments, emits a constant light of higher intensity than the intensity of background noise, thus decreasing the effect of the background noise on the light detector  420  or the light switch enclosure  400 . The first LED  405 , in such embodiments, is used to emit pulsed light signal which the light detector  420  detects when object  450  is in the vicinity.

In some embodiments, each lighting system  100  component comprises, or is associated with, a light switch enclosure  400 . In some embodiments, lighting system  100  comprises a plurality of light sources  110  connected in series, each light source comprising or being associated with a light switch enclosure  400 . 
     Sometimes, light switch enclosures  400  may be used for assignment of unique digital addresses for a plurality lighting system  100  components.

In many embodiments, a plurality of light sources  110  connected in series and each comprising a light switch enclosure  400 , are assigned unique digital addresses to be used for communication. 
     A component of a lighting system  100  component having a master status, which is sometimes also referred to as the master, is placed into an assignment mode. An assignment mode, in some embodiments, is a mode, a function, a feature or a capability of a lighting system  100  to assign addresses  127  to any lighting system  100  component. An assignment mode, in other embodiments, is a mode, a function, a feature or a capability of a lighting system  100  component to assign addresses  127  to any lighting system  100  component. In numerous embodiments, an assignment mode is a function or a setting of any of the lighting system  100  components. In some embodiments, assignment mode is a mode, a function, a feature or a capability 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, in some embodiments, comprises 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. 
     In a number of embodiments, assignment mode comprises a plurality of addresses  127  and means for communicating one of the plurality of addresses  127  to each component to be associated with the address  127 . Assignment mode, in a number of embodiments, comprises means for transmitting or receiving confirmation messages from each of the lighting system  100  components who have received and accepted the addresses  127 . In many embodiments, lighting system  100  components, store the address  127  received from the master and transmit a confirmation message to the master, confirming that they have accepted the address  127  assigned. In some embodiments, the master 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  component accepts the address  127  and returns to the master the confirmation message indicating that the lighting system component has accepted the address  127 . The master stores the address  127  and associates it with lighting system  100  component and uses it for any communication to the lighting system  100  component in the future. For example, light source  110 A accepting address  127 A previously sent by the master sends a confirmation message confirming that light source  110 A component has accepted the address  127 . The master, 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. 
     In some embodiments, light switch enclosures  400  are associated with lighting system  100  components and are used 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 light switch enclosures  400  associated with lighting system  100  components. A master is placed in an assignment mode and is 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 light switch enclosure  400  associated with the light source  110 A. Light detector  420  of the light switch enclosure  400 , in response to the placed object  450 , detects light emitted by LED  405  and light switch enclosure  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. 
     Similarly, the user proceeds to select any number of lighting system  100  components by placing an object  450  in front of light switch enclosure  400  associated of each selected lighting system  100  component. The master, in response to user&#39;s selections, assigns an address  127  to each of the user selected lighting  100  system components. Upon completing all the selections, the user terminates the assignment mode and the master stores all the addresses  127  and lighting system  100  components associated with each of the addresses  127 . The lighting system  100  components use addresses  127  assigned to transmit or receive information or communication among the lighting system  100  components assigned. In some embodiments, this method is used to create a group of lighting system  100  components, or a group of light sources  100 . In many embodiments, this method is used to distinguish a group of lighting system  100  components or light sources  110  from other lighting system  100  components or light sources  110 . In a number of embodiments, each of the groups created or distinguished are controlled separately. 
     In some embodiments, each lighting system  100  component uses a non-volatile memory for storing addresses  127  of one or more lighting system  100  components. Sometimes, one or more addresses  127  of one or more lighting system components belonging to a group or a zone are stored in a non-volatile memory of a lighting system component controlling the group or the zone. In a number of embodiments, address  127  of each lighting system  100  component may comprise a group identifier, uniquely identifying a zone or a group the lighting system  100  component is a part of. In a plurality of embodiments, lighting system  100  controls one or more light sources  110  having a same group identifier by sending one information or an instruction to every member of the group or the zone. In many embodiments, a group identifier is an address  127 . In some embodiments, a group identifier is a part of an address  127 . In a plurality of embodiments, a group identifier comprises an address  127 . In a number of embodiments, a group identifier is an identifier separate from an address  127 . 
     Sometimes, a user assigns a group identifier to one or more light sources  110  using a light switch enclosure  400  by placing an object  450  in the vicinity of, or on top of, the light switch enclosure  400  of the one or more light sources  110 . In some embodiments, a user assigns a group identifier to each of a plurality of light sources  110  using a lighting system  100  component for receiving responses from one or more light sources  110 . The user picks each individual light source  110  by placing an object  450  in the vicinity of, or on top of, the light switch enclosure  400  of each one of the plurality of light sources  110 . The lighting system  100  component receives responses from the each one of the plurality of light sources  110  and assigns the group identifier to each of the light sources  110  that have responded. Sometimes, the mode wherein the light system  100  or a lighting system  100  component assigns group identifiers is called a learn ID mode. The learn ID mode ends when all the light sources  110  which were picked by the user send their responses to a lighting system  100  component in charge of storing or controlling the group. The lighting system  100  or a lighting system  100  component controlling the group then knows which light sources  110  are part of the group, and is able to communicate with the group using the assigned group identifier.

     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. In further embodiments, the line includes a RS-232 connection, a wireless connection or an Ethernet connection. In still further embodiments, the line is any medium supporting or handling any 8/16 bit digital communication. 
     In one embodiment, a master lighting device  11  Oa communicates with a plurality of slave lighting devices  110  via the line. 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. 
     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.
