Title: Intelligent lighting control light synchronization apparatuses, systems, and methods

Description:
RELATED APPLICATION 
     The present application claims priority to U.S. Provisional Patent Application No. 62/321,132, filed on Apr. 11, 2016, entitled “INTELLIGENT LIGHTING CONTROL LIGHT SYNCHRONIZATION APPARATUSES, SYSTEMS, AND METHODS,” which application is incorporated herein by reference in its entirety. 
    
    
     TECHNICAL FIELD 
     The present application relates generally to the field of lighting control systems. 
     BACKGROUND 
     Customizing and automating home lighting control devices is often epitomized by the installation of unsightly lighting switches that are inundated with light switches confusingly mapped to respective fixtures. Automated home lighting control systems can also include large, complex, expensive central hubs that require expert or skilled technicians for installation and/or operation. Smart light bulbs and/or Wi-Fi enabled lightbulbs introduced into any of these contexts or even in simpler ones can disadvantageously be limited by the light switch that it is associated with and/or the lighting fixture itself. For example, if a light switch associated with a smart light bulb is switched off the smart light bulb becomes inoperable. 
     Different light bulb types and models have different properties that determine how they behave to a provided current. The threshold at which a light “pops-on” and the rate at which the light “warms-up” is generally to unique to the specific bulb and depends on factors such as bulb type and bulb manufacturer. Also smart bulbs have their own inherent properties that uniquely drive the bulbs rate of dimming.

     DETAILED DESCRIPTION 
     Following below are more detailed descriptions of various concepts related to, and exemplary embodiments of, inventive systems, methods and components of lighting control devices. 
       FIG. 1A  is a perspective partially exploded view of a lighting control device  100 . The lighting control device  100  includes a switch module  102  including a light switch actuator  106  and a tactile display  104  housed in the light switch actuator  106 . The lighting control device  100  also includes a wall plate cover  108  including a switch module opening  110  extending therethrough. The lighting control device  100  also includes a base module  112  configured for coupling to the switch module  102  via multi-pin socket  114 . The base module  112  is sized and configured for receipt within a one-gang wall electrical box and has a volume corresponding substantially thereto. The base module  112  is configured to be coupled to a wall electrical box via connection tabs  116  and fastener apertures  118  in the connection tabs  116 . 
     The light switch actuator  106  includes an outer actuation surface  122 , which as discussed further herein may be composed of glass. The actuation surface  122  is movable, for example, by pushing on the curved foot  120  to cause the light switch actuator  106  to pivot, for example. The pivoting of the light switch actuator  106  and the actuation surface  122  causes a contact component (shown in  FIG. 2 ) of the switch actuator  106  to move from a first position to a second position. Movement of the contact component causes a connection of an electrical flow path, for example by allowing two electrical contacts to connect or by connecting the contact component with an electrical contact. The connecting of the electrical flow path, permits electrical energy supplied by a power source connected to the base module  112  to energize or activate the tactile display  104 , as discussed in further detail herein. The tactile display  104  is structured in the switch module to move contemporaneously with at least a portion of the actuation surface  122  and with the actuator  106 . When activated or energized, the tactile display  104  allows a user to define or select predefined lighting settings where the lighting settings change the voltage or power supplied to one or more light fixtures. The change in power supplied to the light fixtures may include a plurality of different voltages supplied to each fixture and may be based on various parameters including, but not limited to, location, light intensity, light color, type of bulb, type of light, ambient light levels, time of day, kind of activity, room temperature, noise level, energy costs, user proximity, user identity, or various other parameters which may be specified or detected. Furthermore, the lighting control device  100  may be connected to all of the lights in a room or even in a house and can be configured to operate cooperatively with one or more other lighting control devices  100  located in a unit or room and connected to the same or distinct lighting fixtures. 
       FIG. 1B  is a fully exploded view of the lighting control device  100  of  FIG. 1A . As demonstrated in  FIG. 1B , the tactile display  104  is positioned between the outer actuation surface  122  and the light switch actuator  106 . The actuation surface  122  may be composed of an impact-resistant glass material permitting light from the tactile display  104  and/or a clear sight of path for sensors  127  or other lights, such as a light from light pipe  126  indicating activation to pass through the actuation surface  122 . The tactile display  104  is composed of a polymer-based capacitive touch layer  124  and a light emitting diode panel  125 , which are controlled via one or more modules or processors positioned on the printed circuit board  129 . The tactile display  104  is housed within a recess  131  of the light switch actuator  106  beneath the actuation surface  122 . The light switch actuator  106  may be formed as a thermoplastic housing including a housing cover  133  and a housing base  135 . The light switch actuator housing cover  133  is pivotally connected to the housing base  135  via pins  136  and the housing cover  133  is biased with respect the housing base  135  via torsion spring  137 . In particular embodiments, the light switch actuator housing cover  133  may be configured to slide or otherwise translate or rotate. The outer actuation surface  122  is biased with the switch actuator housing cover  133  and moves contemporaneously therewith in concert with the tactile display  104  housed in the cover component  133  of the light switch actuator  106 . The light switch actuator  106  includes a switch pin  128  movable between positions to close an open circuit on the primary printed circuit board substrate  150 , which board also houses a switch controller or processor. In certain embodiments the light switch actuator  106  may include a circuit board stack, including the primary printed circuit board substrate  150  and a secondary printed circuit board  138  The light switch actuator  106  may include a latch  136  for coupling to the base module  112  (e.g. as the light switch actuator  106  is passed through the opening  110  in the wall plate cover  108 ), which latch causes the light switch actuator  106  to click into place. The housing base  135  includes a multi-pin connector or plug  134  configured to engage the multi-pin socket  114  of the base module  112 . 
     The lighting control device  100  includes a mounting chassis  142  configured to be installed to an electrical wall box. The mounting chassis  142  creates an even surface for installation of the other modules (e.g., the base module  112  and the switch module  102 ). Once the base module is connected to the electrical wall box via the mounting chassis  142 , the wall plate cover  108  can be coupled to the mounting chassis  142  and the light switch actuator  106  can be inserted through the switch module opening  110 . In particular embodiments, the wall plate cover can be coupled to the mounting chassis  142  and/or the tabs  116  of the base module via magnets. The magnets may be recessed within openings of a portion of the wall plate cover  108 . As noted, the base module  112  is configured to be coupled to a wall electrical box via connection tabs  116 . The base module  112  is further configured to be electrically coupled to a power source and to one or more light fixtures wired to the electrical box. Accordingly, the base module  112  provides an interface between a power source, the light switch actuator  106 , and one or more light fixtures. The base module includes a processor  140  and a circuit board  141  for managing the power supplied by the power source and routed to the one or more light fixtures in accordance with a light setting selection identified via the light switch actuator  106  or the tactile display  104 . 
     One or more of the processor on the printed circuit board  15038   a  or  138   b    130  and the base module processor  140  may include wireless links for communication with one or more remote electronic device such as a mobile phone, a tablet, a laptop, another mobile computing device, one or more other lighting control devices  100  or other electronic devices operating in a location. In certain implementations the wireless links permit communication with one or more devices including, but not limited to smart light bulbs, thermostats, garage door openers, door locks, remote controls, televisions, security systems, security cameras, smoke detectors, video game consoles, robotic systems, or other communication enabled sensing and/or actuation devices or appliances. The wireless links may include BLUETOOTH classes, Wi-Fi, Bluetooth-low-energy, also known as BLE (BLE and BT classic are completely different protocols that just share the branding), 802.15.4,Worldwide Interoperability for Microwave Access (WiMAX), an infrared channel or satellite band. The wireless links may also include any cellular network standards used to communicate among mobile devices, including, but not limited to, standards that qualify as 1G, 2G, 3G, or 4G. The network standards may qualify as one or more generation of mobile telecommunication standards by fulfilling a specification or standards such as the specifications maintained by International Telecommunication Union. The 3G standards, for example, may correspond to the International Mobile Telecommunications-2000 (IMT-2000) specification, and the 4G standards may correspond to the International Mobile Telecommunications Advanced (IMT-Advanced) specification. Examples of cellular network standards include AMPS, GSM, GPRS, UMTS, LTE, LTE Advanced, Mobile WiMAX, and WiMAX-Advanced. Cellular network standards may use various channel access methods e.g. FDMA, TDMA, CDMA, or SDMA. In some embodiments, different types of data may be transmitted via different links and standards. In other embodiments, the same types of data may be transmitted via different links and standards. 
       FIG. 2A  shows the lighting control device  100  of  FIG. 1A  mounted on a wall  200 . As demonstrated in  FIG. 2A , the base module  112  is not visible upon installation of the lighting control device  100  in view of the wall plate cover  108 . Because the wall plate cover  108  attaches to the base module  112 , the wall plate cover  108  appears to be floating on the wall  200 . The lighting control device  100  may be activated by a user  103  interacting with the outer actuation surface  122  and the tactile display  104 . 
       FIGS. 2B and 2C  illustrate multi-switch configurations of multiple lighting control device.  FIGS. 2B and 2C  illustrate a two switch and three switch embodiment respectively where the lighting control devices  202  and  203  each include a light switch actuator  106  as well as auxiliary switches  204  and  208 , as well as 2 and 3 base modules  112 , respectively. 
       FIGS. 3A-3F  illustrate a lighting control device transitioning through various lighting settings and a room having lighting fixtures controlled by the lighting control device. 
     In  FIG. 3A , the lighting control device  300  is connected to a base module positioned behind the wall plate  308 . The lighting control device  300  includes a dynamic light switch actuator  306 , operable in a manner similar to the light switch actuator discussed in connection with  FIGS. 1A-2C , and an auxiliary light switch actuator. As demonstrated in  FIG. 3A  by the unilluminated outer actuation surface  322  of the light switch actuator  306  is inactive and not energized. In response to a user  103  moving the actuation surface  322  of the light switch actuator  306 , the light switch actuator  306  begins to become energized, as shown in  FIG. 3B . The energization or activation of the light switch actuator  306  is signaled by the power light indicator  305  and by full lighting setting icon  351 . As shown in  FIG. 3C  where the icon  351  is fully lit (rather than partially lit as in  FIG. 3B ), the light switch actuator  306  is fully energized. In this particular configuration, the primary lights  309  and  310  are illuminated at full power.  FIG. 3D  shows the transition between lighting settings. As demonstrated in  FIG. 3D , this transition is facilitated via user  103  completing swiping gesture  312  across the tactile display  304  and along the actuation surface  322 . As the user completes the gesture  312 , the icon  351  is swiped from the tactile display  304  as the tactile display toggles to a new light setting shown in  FIG. 3E . The new light setting shown in  FIG. 3E  is represented or identified by the dinner icon  352 . The new light setting shown in  FIG. 3  has the light fixture  309  powered down and has caused lamp  316  and sconces  318  to become illuminated to change the lighting scene in the room. The change in the light setting causes a change in distribution of power to certain lighting fixture based on the selected lighting setting. The light switch actuator  306  may be pre-programmed with a plurality of lighting settings or may be configured with particular lighting settings as specified by the user  103 . A further swiping gesture  315  shown in  FIG. 3F  or a different gesture are used to transition from the lighting setting of  FIG. 3F  represented by icon  352  to a further lighting setting. 
       FIG. 4  provides a flow diagram of operations of a system for controlling a lighting control device.  FIG. 4  illustrates control operations of a control system, such as processor  130  configured to control the lighting control device  100  or  300 , in accordance with various embodiments of the present invention. At  401 , the tactile display housed in the light switch actuator is activated by moving the light switch actuator, for example by moving the actuation surface of the light switch actuator. At  402 , the light fixtures electrically coupled to the light switch actuator via a base module are powered as the movement of the light switch actuator causes a contact component to move into a new position and thereby permit or cause an electrical flow path between a power source and the light fixture(s) to be closed. The tactile display housed in the light switch actuator is moved contemporaneously with the actuation surface. At  403 , a lighting setting selection request is received via the tactile display, for example by a particular motion or motions on the tactile display. The lighting setting selection request identifies a lighting setting from among a plurality of lighting settings. A user may swipe multiple times to toggle through the plurality of lighting settings or may conduct a specific motion that corresponds to a particular lighting setting including, but not limited to, a half swipe and tap to achieve a light intensity of all the connected light fixtures at half of their peak output. The lighting settings identify distinct power distribution schemes for one or more light fixtures connected to the light switch module. At  404 , a power distribution scheme is identified. At  405 , the identified power distribution scheme is transmitted, for example by the base module responding to control signals from the light switch actuator, to adjust one, some, or all of the lights based on the power distribution scheme corresponding to the lighting setting selected. The power distribution schemes or profiles may be stored in a memory device of the lighting control device. In certain embodiments, the power distribution schemes may be adjusted to account for other parameters such as ambient lighting from natural light or an unconnected source. In certain embodiments the power distribution schemes may be adjusted based on one or more other sensor parameters. In particular embodiments, the lighting setting may be adjusted by automation based on time of day, sensed parameters such as light, temperature, noise, or activation of other devices including, but not limited to, any electronic device described herein. 
       FIG. 5  shows a flow diagram of system for remotely operating a lighting control device. In particular embodiments, the lighting control device  100  or  300  may be operable from a remote device if the actuator switch is activated or energized. In such instances, the remote device may include one or more computer program applications, such as system  500 , operating on the device to communicate with and control the lighting control device. Accordingly, at  501 , the control system  500  initiates a connection module to generate a communication interface between a mobile electronic device and a light switch module. The connection module may cause the remote device to send one or more wireless transmission to the lighting control device via a communication protocol. At  502 , the control system  500  causes the remote device to generate a display of icons on a display device of the mobile electronic device to facilitate selection of a lighting setting. At  503 , the control system  500  receives a lighting setting selection based on the user selecting a particular icon. At  504 , a transmission module causes the lighting setting selected to be transmitted to the lighting control device so that the light switch module and/or the base module can cause the power distribution scheme corresponding to the lighting setting to be transmitted to the lighting fixtures. The tactile display of the lighting control device may be updated in concert with receipt of the lighting setting to display the icon selected on the mobile electronic device and corresponding to the lighting setting selected on the tactile device. 
       FIG. 6  illustrates a flow diagram of a system for remotely configuring operations of a lighting control device. The remote device may include devices including, but not limited to a mobile phone, a mobile computing device or a computing device remote from the light control device. At  601 , the mobile electronic device generates a communication interface with the light switch module. At  602  a light fixture identification module initiates a sensor based protocol to identify a parameter associated with one or more light fixtures connected to the light switch control module. At  603 , a display selection module causes a display of an icon to appear on a display device of the mobile electronic device. At  604 , a lighting setting configuration module allows a user to create a power distribution scheme or profile for the light fixtures identified based on the identified parameters and a user specified input related to light intensity. At  604 , a storage module is used to the store the power distribution scheme and associate a particular lighting setting icon with the power distribution scheme. At  605 , a transmission module transmits the power distribution scheme and the associated icon to the light switch control module. 
       FIG. 7  is a schematic of a lighting control system apparatus. The lighting control system apparatus includes a lighting control module  700 . The lighting control module  700  can be configured like the lighting control device  100  to include a switch module removably coupled to a base module. The lighting control module  700  is configured to adjust a lighting scene by causing a change in the power distribution scheme to one or more lighting fixtures of lighting circuit  750 . In connection with changing the power distribution scheme, the lighting control module  700  includes a detector circuit  712  for detecting one or more electrical parameters related to the lighting control module  700 . As discussed further herein, these electrical parameters may provide information related to the configuration of the lighting control module  700  and/or the configuration of one or more components connected to the lighting control module  700 . The lighting control module  700  also includes a power circuit  714  for regulating the power flow to and from the lighting control module  700 . The power circuit  714  and the detector circuit  712  are communicably coupled for bidirectional communication with one or more controllers  720 . In some embodiments, the controller  720  may include a controller on the switch module which may communicate with the detector circuit and the power circuit through a separate controller positioned in the base module. The power circuit  714  and  712  are positioned in a base module and are connected to the lighting circuit  750 . The control of electricity from the power circuit  714  to the lighting circuit  750  is regulated (directly or indirectly) by the controller  720 . The power circuit  714  may include one or more transformers or power converters and may be configured for power isolation to maintain AC current flow from interacting with various DC components. The detector circuit may include one or more components configured to measure current, voltage, impedance or other electrical properties, signals, or data. 
     The power circuit  714  can be configured to adjust the signal supplied (input signal), which is related to the power supplied by it, to the lighting circuit  750 . For example, the power circuit  714  can comprise a tunable voltage source that can supply an input voltage signal with tunable voltage amplitude to the lighting circuit  750 . The input voltage signal can be an AC and/or a DC signal whose amplitude can be tuned by the power circuit  714 . In some implementations, the power circuit  714  can comprise a tunable current source that can supply an input current signal with varying current amplitude to the lighting circuit  750 . For example, the input current signal can be an alternating (AC) and/or direct (DC) whose amplitude can be varied by the power circuit  714 . In some implementation, the power circuit  714  can comprise both tunable voltage source and tunable current source. The power circuit  714  may be configured to supply an input voltage and/or current signal at discrete amplitudes. The power circuit  714  may be configured to increase/decrease the quantity of power supplied to the lighting circuit  750 , for example by increasing/decreasing the amplitude of the input voltage and/or current signal. 
     One or more properties of the input signal can be controlled by the controller  720 . The controller  720  and power circuit  714  can interact electronically by wire or wirelessly. The controller  720  can send a control signal to the power circuit  714  that may determine the properties of the input signals (voltage and/or current signals). For example, the control signal may contain data that includes an array of numerical values of amplitudes (and frequencies) of sinusoidal input signals. The power circuit  714  may set the amplitude and frequency of the input signals (voltage and/or current signals) based on the control signal. 
     The response of the lighting circuit  750  measured by the detector circuit  712  may include one or more of current, voltage and impedance. The response of the lighting circuit  750  may be represented by an analog signal, i.e., a signal that can continuously vary with time. In some implementations, the detector circuit  712  may include a voltage sensing circuit that can detect a voltage signal (e.g., voltage across the lighting circuit  750 ). In some implementations the detector circuit  712  can include a current sensing circuit that can detect a current signal (e.g., the current flowing into the lighting circuit  750 ). In some implementations, the detector circuit  712  can include an impedance sensing circuit that detects the impedance of the lighting circuit  750 . 
     The detector circuit  712  and power circuit  714  can interact by wire and/or wirelessly. The power circuit  714  can send a signal to the detector unit  712  based on which the detector circuit starts (or ends) detecting the response of the lighting circuit  750 . For example, the power circuit  714  may send a notification signal to the detector circuit  712  that indicates that the power circuit  714  is about to send an input signal (voltage and/or current signal) to the lighting circuit  750 . Based on the notification signal, the detection circuit  712  may begin detecting the response of the lighting circuit  450 . Additionally, or alternately, the power circuit  714  may send a notification signal to the detector circuit  712  that indicates that the detection circuit  712  may end detecting the response of the lighting circuit  750 . 
     The detector circuit  712  and the controller  720  can interact by wire and/or wirelessly. For example, the detector circuit  712  may send detector signal to the controller  720  that contains data that represents information related to the detected response (e.g., voltage, current, impedance etc.) of the lighting circuit  750 . As described before, the response of the lighting circuit  750  may be represented by an analog signal. In one implementation, the detector circuit  712  includes an analog-to-digital converter (ADC) that can convert the analog response signal to a digital response signal. Converting the analog response signal to the digital response signal may involve sampling the analog response signal at certain times, for example, sampling periodically at a sampling frequency. For example, the analog response signal can be sampled at greater than 1 KHz (more than 1000 samples per second) or at greater than 10 KHz. The sampled analog signal is rounded off to the nearest available digital value (sometimes referred to as “levels”) of the ADC. The signal resolution of the ADC may depend on the range of analog signal that the ADC can detect (e.g., range of voltage/current values), and the number of available digital values. For example, the resolution of an 8-bit ADC (256 available digital values), having 5.12V (volts) range (e.g., from 0V to 5.12 V), will be 0.02 volts. This 8-bit ADC may convert a sampled analog signal to the nearest 0.02V-multiple value. For example, a 0.175 V sampled analog signal may be converted to a 0.18 V signal. The time resolution of the ADC (e.g., the time resolution of the digital response signal) depends at the sampling frequency, i.e., the frequency at which the ADC samples the analog response signal. The sampling frequency of the ADC can be set to a value that is greater than twice the maximum frequency of the sampled analog signal (sometimes referred to Nyquist frequency). 
     In some implementations, the controller  720  can adjust the range of analog signals that the ADC in the detection circuit  712  can detect. The controller  720  can, for example, send a “reference” signal to the ADC that can determine the range of the ADC. For example, referring to the 8-bit ADC example discussed before, the controller  720  may send a 2.56 V reference signal to the ADC. As a result, the range of the 8-bit ADC may change to 2.56V (e.g., from 0V to 2.56 V). Changing the range of an ADC may also change the resolution of the ADC. For example, if the range of an 8-bit ADC is changed from 5.12V to 2.56V by the controller  720 , the resolution of the 8-bit ADC may change from 0.02V to 0.01V. 
     The detector signal (from the detector circuit  712  to the controller  720 ) can include data that represents information about the digital response signal. The detector signal may also include the sampling times corresponding to the digital response signal. The controller  720  can make a determination about one or more properties of the lighting circuit  750  based on the detector signal for one or more input signals. For example, the controller  720  may compare the detected response signals with response data of known circuits in a database. The known circuits may include lighting circuits with different types of light bulbs (e.g., incandescent, fluorescent, LED, halogen, high intensity discharge, magnetic low-voltage, electronic low-voltage), with different number of light bulbs, or a combination of both. The database may also include one or more input signal data that may be related the response data. For example, the response data, for a known circuit, may represent the response of the known circuit to an input signal (e.g., time-dependent signal) represented by the input data. 
     The input signal data of a known circuit in the database may represent information about one or more properties of the input signals (voltage and/or current signals). For example, the input signal data can include information about the amplitude and frequency of a sinusoidal input signal. The response data of the known circuit may contain information about one or more properties of the response (e.g., voltage, current, impedance etc.) signal of the known circuit corresponding to an input signal. For example, the response data may comprise an array of numerical values that represents the amplitude of the response signals (e.g., amplitude of voltage and/or current signals) as a function of time. 
     As described before, the controller  720  can send a control signal to the power circuit  714  that may determine the properties of the input signals (voltage and/or current signals) supplied by the power circuit  714  to lighting circuit  750 . In some implementations, the control signal may include input signal data (e.g., the amplitudes and frequencies of the input signals represented by the input signal data). The power circuit  714  may supply input signals to the lighting circuit  750  based on the received input signal data. The detector circuit  712  may detect the response of the lighting circuit  750  to the aforementioned input signals, and send the detected response signals (e.g., digital response signal from the ADC in the detector circuit  712 ) to the controller  720 . The controller  720  may compare (e.g., by correlation) the detected response signals with the response data. Based on this comparison, the controller  720  may determine one or more properties of the lighting circuit  750 . 
     In one implementation, the power circuit  714  is configured to supply a small current input signal (configured leak electricity) that does not light up the bulbs in the lighting fixtures of the lighting circuit  750 . However, the small current input signal may be sufficient to detect a response signal or power draw from the lighting circuit  750 . In one implementation, the current input signal can be less than 25 milliamps, less than 15 milliamps, and/or less than 10 milliamps. The power circuit  714  may be configured to increase the power supplied by successive input signals. This can, for example, be achieved by successively increasing the amplitude of the voltage/current input signal 
     In one implementation, the controller  720  is configured to select a diming profile (e.g., forward phase, reverse phase, non-dimmable) of the bulb (whose type has been determined by the controller  720 ) in the lighting circuit  750 . The dimming profiles of the various light bulb may be stored in the database of the controller  720 . Based on the diming profile, the controller may send a control signal to the power circuit  714  to change the power supplied to the lighting circuit based on data in the diming profile. The controller  720  may be configured to determine the wattage rating of the bulb in the lighting circuit  750 . The wattage can, for example, be determined by the power consumed by the lighting circuit  750 . The power consumed by the lighting circuit  750  may be determined by multiplying the detected digital voltage response with the detected digital current response of the lighting circuit  750 . Based on the wattage of the lighting circuit  750 , the controller may identify the company that manufactures the bulb in the lighting circuit  750 . 
       FIG. 8  is a schematic of a lighting control module of  FIG. 7 . The lighting control module  700  is depicted separated into a base lighting control module  812  and a switch module or switch controller  802 . As described herein, the switch module  802  may include a tactile interface and a switch actuator, such as the tactile display  104  and the light switch actuator  106  described herein. The switch module  802  can also house the controller  720 . The power circuit  714  may include a transformer  818 , a power isolator and DC converter  814 , and a dimmer, such as a TRIAC dimmer  813 . In some embodiments, the power circuit  714  may include a MOSFET dimmer. The detection circuit  712  may include a voltage and current sensor  816 . The power isolator separates the analog AC current from the low power or DC digital components in the base lighting control module  812  and the switch module  802 . 
     The base lighting control module  812  includes a ground terminal  830  for grounding various electrical components container in the module  812 . The base light control module  812  includes a neutral terminal  828  for connecting to a neutral wire, a line terminal  826 , and a load terminal  822 . As shown in  FIG. 8 , the voltage and current sensor(s) are coupled to the load line to detect changes in the voltage or current along the line carrying power to one or more light fixtures  824  connected to the lighting circuit ( 750 ). The base lighting control module  812  also includes a controller  840  communicably coupled to the controller  720 . The base lighting control module  812  also includes LED indicator lights  842  and  841  for indicating information regarding the status of the base lighting control module  812 . For example, in some embodiments LED indicator light  841  can indicate if a neutral wire is connected while LED indicator light  842  can indicate if a 3-way connection is connected. 
       FIGS. 9A-9N  are lighting power graphs.  FIG. 9A  illustrates a synchronization curve of multiple light circuits at a plurality of different luminous intensity plateaus. The luminous intensity plateau need not correspond with the bulb peak luminous intensity, but can correspond to a particular plateau for the particular bulb for a specific scene.  FIG. 9B  illustrates a synchronization curve for different lighting circuits with a Smart-bulb. As demonstrated in  FIG. 9B , the smart-bulb may have a pre-set ramp time that the lighting control module may have to accommodate for with respect to other non-smart bulb in order to synchronize their ramp up (or ramp down) rates (change in power over time).  FIG. 9C  shows synchronization of different types of bulbs in different lighting circuit, while  FIG. 9D  shows synchronization for various LED hosting lighting circuits.  FIGS. 9E-9H  show synchronization curves for lighting circuits where the circuits don&#39;t have a neutral wire in contrast to  FIG. 9A-9D . 
       FIGS. 9I and 9J  illustrates the power output response over time of bulbs upon turning them on. In order to synchronize instant on behavior at the moment of user interaction embodiments proactively address the warm up time for the bulbs. Some bulbs require an excitement period of electrical power to warm up, a circuit may be prepared for a brief period of time with a low electrical power to the bulb at a value just under the bulb&#39;s pop-on value (value of power at which the bulb will first turn on). For example, a delay caused by the bulb warming up can often be noticed with basic 3rd-party dimmers initially set to a low dim level (10-30%) and multiple type of bulbs, like CFLs, LEDs, and some halogens The low level of electrical power provided in accordance with certain embodiments is configured to not be enough to illuminate the bulb, but instead only warm up the circuit&#39;s componentry so that at the moment the bulb or cluster of bulbs are turned on to a low dim level, the inherent delay is minimized. 
     The warm up period is only initiated once the user begins to interact with the switch for example the warm up period can be initiated—(1) upon approach, which may be recognized by one or more proximity and/or occupancy sensors housed in the switch in one or more of the switch module and the base module, (2) after interaction with the touch screen on the switch, or (3) in response to interaction with a mobile application operating or activated, at least in part, through a mobile computing device. Each of these actions typically precedes an action taken by the user to turn on the lights; therefore, the bulbs whose circuitry is cold/room-temperature from being off for a long period of time (for example, &gt;1 hr) will be warmed and ready to instantly turn on. 
       FIGS. 9K and 9N  illustrate the power response of two different bulbs over time. Methods of synchronizing different bulb types that illuminate brighter at lower power levels in accordance with embodiment disclosed herein can benefit from learned or informed bulb illumination response over time. As different types of bulbs produce a variety of perceived illumination levels given the same amount of power, different types of ramp curves may be provided to each circuit so that the net illumination ramp appears more similar. For example, a linear ramp at a greater power level for an incandescent bulb can pair well with an exponentially ramping power curve to an LED. 
     As shown in  FIGS. 9M and 9N  in some cases the perceived illumination at the bulb&#39;s pop-on value is too great to initiate simultaneously with accompanying bulbs. Therefore, the initial power for the bulb may be delayed to provide time for the bulbs on other circuits to catch up-a head start. Once the illumination of the circuits granted a head start is bright enough to complement the bulb with the greater pop-on, power is then provided to enable the lagging bulb to continue ramping up in sync along with its counterparts. 
       FIG. 10  is a flow diagram of a lighting control system synchronization apparatus for synchronizing lighting control modules for brightening lights. Synchronization process  1000  may be achieved remotely via a remote computing device configured for communicably coupling to a light switch module. At  1001 , the remote computing device wirelessly connects or initiates a communication protocol with a first switch module. At  1003 , the remote computing device determines a plateau of a first light switch for a particular lighting scene. This plateau may not be the lights peak lighting output, but may represent the peak for a particular scene. The detection circuit of the switch module is used to determine a plateau of a first light switch for a particular lighting scene. The power circuit may transmit a test current to determine the first plateau for the scene. For example, the scene may identify either a particular light output desired or power. The power circuit may transmit a test current to determine the rate of energy transfer required to achieve the light output or desired power, which depends on the bulb type connected to the light fixture. The detection circuit can measure the actual response of the light circuit to the test signal. In some embodiments, the detection circuit includes an optical sensor to measure a change in light output. At  1004 , the remote computing device connects to a second switch, or lighting control module connected to a separate light circuit and light fixture. The second light circuit and light fixture connected to the second lighting control module can be in the same room, but independently control the light fixture that it is connected to. The light fixtures in concert may be used to create a particular lighting scene. At  1004 , the remote computing device determines a plateau of a second light switch for the particular lighting scene. The remote computing device is then used to calculate and/or analyze at  1006 , whether the rate of plateauing is the same for the distinct lighting circuits connected to the distinct light control modules. If the rate of transmission to reach the respective peaks of the lights is determined to be the same, then at  1007  power is transmitted from the first and second switches at the same time and at the same rate. If, however, the detection circuits indicate that it takes a different amount of time for the light fixture connected to the first light control module to reach the specified respective plateau (measured in light output or power) than it does for the second switch to reach the specified respective plateau, then the rate of energy transfer required to reach respective peaks at the same Time T 1  is determined at  1008 . The time T 1  may be the time for either one of the fixtures or it may be a preset time, such as 1 second. At  1009 , the remote computing device sends commands to each of the light control modules to cause them to transmit electricity at the requisite respective rates to cause the lights to reach their respective plateaus for the particular light scene at the same time. In some embodiments, the rates may be changed by adjusting the resistance applied by the respective power circuits of the light switch modules. Similarly, the voltage and/or current may be varied, stepped up or down, to change the rate of transfer and/or the time required to reach the output plateau for the respective light fixtures to coordinate the ramping up of light. 
       FIG. 11  is a flow diagram of a lighting control system synchronization apparatus for synchronizing diming of lighting control modules. In contrast to the system described in connection with  FIG. 10 , system  1100   FIG. 11  is for determining the rate of extinguishing, finishing, or dimming to synchronizing the rates that particular lights, which may include different types of bulbs connected on different light circuits are turned down. At  1101 , the current lighting scene profile is determined and at  1102  the desired lighting scene profile is identified. Based on the current profile and the desired or selected new profile a current plateau, A 1  and a new lower plateau A 2  are determined at  1103  for a first light fixture connected to a first light control module. At  1104  plateaus B 1  and B 2  corresponding to the current plateau (e.g. of peak light output or power) are determined for a second light fixture. The values for these plateaus are then used at  1105  and  1106  to determine the rate of dimming needed for each light fixture to move from their respective plateaus A 1  to A 2  and B 1  to B 2  to finish at the same time Td. Based on the determined rates, the first light control module is causes the first light fixture(s) to dim at the rate R 1  and the second light control module causes the second light fixture(s) to dim at the rate R 2  so that the lights move to their new respective dimmer plateaus or extinguish contemporaneously. 
       FIG. 12  is a schematic of lighting control modules communicably coupled to a remote device and one another for synchronization. A first lighting control module  700   1  is wired to a first light circuit including, Light Fixture(s) A,  1202 . The first lighting control module can detect the rate of ramping up and ramping down of the Light Fixture(s) A, via the detection circuit  712  and the power circuit  714 . Similarly, a second lighting control module  700   2  is wired to a second light circuit including, Light Fixture(s) B,  1203 . The second lighting control module can detect the rate of ramping up and ramping down of the Light Fixture(s) B, via the detection circuit  712  and the power circuit  714  of the second lighting control module  700   2 . Once the respective rates of ramping up and/or down are determined the light control modules may wireless communicate over communication channel  1206  with one another via communication modules  1201  to coordinate dimming or brightening in synchronization. As discussed herein, a remote computing device  1204  may communicate with both of the devices  700   1  and  700   2  wirelessly over communication pathways  1205   1  and  1205   2  respectively to cause the lighting control modules to determine the rates of brightening or dimming and/or to cause them to turn down/up their respective light fixtures in synchronization.

Implementations of the subject matter described in this specification can be implemented as one or more computer programs, i.e., one or more modules of computer program instructions, encoded on computer storage medium for execution by, or to control the operation of, data processing apparatus. 
     A computer storage medium can be, or be included in, a computer-readable storage device, a computer-readable storage substrate, a random or serial access memory array or device, or a combination of one or more of them. Moreover, while a computer storage medium is not a propagated signal, a computer storage medium can be a source or destination of computer program instructions encoded in an artificially generated propagated signal. The computer storage medium can also be, or be included in, one or more separate physical components or media (e.g., multiple CDs, disks, or other storage devices). 
     The operations described in this specification can be implemented as operations performed by a data processing apparatus on data stored on one or more computer-readable storage devices or received from other sources. 
     The term “data processing apparatus” encompasses all kinds of apparatus, devices, and machines for processing data, including by way of example a programmable processor, a computer, a system on a chip, or multiple ones, or combinations, of the foregoing. The apparatus can include special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application specific integrated circuit). The apparatus can also include, in addition to hardware, code that creates an execution environment for the computer program in question, e.g., code that constitutes processor firmware, a protocol stack, a database management system, an operating system, a cross-platform runtime environment, a virtual machine, or a combination of one or more of them. The apparatus and execution environment can realize various different computing model infrastructures, such as web services, distributed computing and grid computing infrastructures. 
     A computer program (also known as a program, software, software application, script, or code) can be written in any form of programming language, including compiled or interpreted languages, declarative or procedural languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, object, or other unit suitable for use in a computing environment. A computer program may, but need not, correspond to a file in a file system. A program can be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document), in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub programs, or portions of code). A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network. 
     The processes and logic flows described in this specification can be performed by one or more programmable processors executing one or more computer programs to perform actions by operating on input data and generating output. The processes and logic flows can also be performed by, and apparatus can also be implemented as, special purpose logic circuitry, e.g., a FPGA (field programmable gate array) or an ASIC (application specific integrated circuit). 
     Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor will receive instructions and data from a read only memory or a random access memory or both. The essential elements of a computer are a processor for performing actions in accordance with instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto optical disks, or optical disks. However, a computer need not have such devices. Moreover, a computer can be embedded in another device, e.g., a mobile telephone, a personal digital assistant (PDA), a mobile audio or video player, a game console, a Global Positioning System (GPS) receiver, or a portable storage device (e.g., a universal serial bus (USB) flash drive), to name just a few. Devices suitable for storing computer program instructions and data include all forms of non-volatile memory, media and memory devices, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto optical disks; and CD ROM and DVD-ROM disks. The processor and the memory can be supplemented by, or incorporated in, special purpose logic circuitry. 
     To provide for interaction with a user, implementations of the subject matter described in this specification can be implemented on a computer having a display device, e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor, for displaying information to the user and a keyboard and a pointing device, e.g., a mouse or a trackball, by which the user can provide input to the computer. Other kinds of devices can be used to provide for interaction with a user as well; for example, feedback provided to the user can be any form of sensory feedback, e.g., visual feedback, auditory feedback, or tactile feedback; and input from the user can be received in any form, including acoustic, speech, or tactile input. In addition, a computer can interact with a user by sending documents to and receiving documents from a device that is used by the user; for example, by sending web pages to a web browser on a user&#39;s user device in response to requests received from the web browser. 
     Implementations of the subject matter described in this specification can be implemented in a computing system that includes a back end component, e.g., as a data server, or that includes a middleware component, e.g., an application server, or that includes a front end component, e.g., a user computer having a graphical display or a Web browser through which a user can interact with an implementation of the subject matter described in this specification, or any combination of one or more such back end, middleware, or front end components. The components of the system can be interconnected by any form or medium of digital data communication, e.g., a communication network. Examples of communication networks include a local area network (“LAN”) and a wide area network (“WAN”), an inter-network (e.g., the Internet), and peer-to-peer networks (e.g., ad hoc peer-to-peer networks). 
     The computing system can include users and servers. A user and server are generally remote from each other and typically interact through a communication network. The relationship of user and server arises by virtue of computer programs running on the respective computers and having a user-server relationship to each other. In some implementations, a server transmits data (e.g., an HTML page) to a user device (e.g., for purposes of displaying data to and receiving user input from a user interacting with the user device). Data generated at the user device (e.g., a result of the user interaction) can be received from the user device at the server.
