Before describing the invention in further detail, it may be useful to describe a few example environments in which various embodiments of the present invention can be implemented. One such example is that of illustrated in FIG. 1.
FIG. 1 illustrates exemplary lighting control systems 101A-101C in accordance with one embodiment of the invention, and implemented in an environment 100 comprising various user systems 103 connected to the lighting control systems 101A-101C via their respective network connection 102 via a communication medium 110. The communication medium 110 may be a wired system (e.g., a coaxial cable system, a fiber optic cable system, an Ethernet cable system), or a wireless network system (e.g., a wireless personal area network, a wireless local area network, a cellular network.)
As shown, various user systems 103 such as a smart phone 104 (e.g., iPhone®), a desktop computer 105, a laptop computer 106, and a tablet 107 (e.g., iPAD®), through their respective network connections 102, can either interact directly or indirectly with one or more of the n lighting control systems 101A-101C to control one or more lighting fixtures coupled to the lighting control systems. For example, a network connection 102 includes wired connections (e.g., Digital Subscriber Line (DSL), optical), wireless connections (e.g., Wi-Fi.) In various embodiments, a network connection 102 may include an ad hoc network, an intranet, an extranet, a virtual private network (VPN), a local area network (LAN), a wireless LAN (WLAN), a wide area network (WAN), a portion of the Internet, a portion of the Public Switched Telephone Network (PSTN), a cellular telephone network, or any combination thereof.

A lighting control platform can be hosted by the lighting control systems 101A-101C, which may be accessed by a user using any user system 103 (e.g., 104, 105, 106, and 107). The user system 103 can display any interface related to the lighting control system and allow a user to interact with the lighting control system thereby controlling or adjusting the light sources of the lighting fixture that are connected to the lighting control systems. For example, the user system 103 may be configured to receive an input from a user, to transmit the input to one or more lighting control systems of the n lighting control systems 101A-101C, and to receive status updates from the n lighting control systems 101A-101C. The interfaces may have different designs for different user systems 103. One of ordinary skill in the art will understand that other interfaces related to the lighting control may be created to facilitate the lighting control experience.
In one embodiment, a user may download a client component of a lighting control system. The client component may be executed locally at a user system 103, whereas the lighting control system may provide back-end support for the client component and may be responsible for maintaining the lighting control data, processing inputs from users, controlling one or more lighting fixtures, and transmitting instructions to various user systems 103. As illustrated, one or more lighting control systems 101A-101C may be connected to a communication medium and may operate seamlessly together.
FIG. 2 is a diagram illustrating an example lighting control system 200 in accordance with an embodiment of the invention. In various embodiments, the lighting control system 200 may comprise a communication module 201, a memory 202, and a processing module 203. The communication module 201 may be coupled to the memory 202. The processing module 203 may be coupled to the memory 202. In various embodiments, the memory 202 may be a non-volatile memory that may retain the stored information even when not powered, such as EEPROM/PROM(s). Accordingly, boot programs and basic input/output system (BIOS) programs are stored in the memory 202. In various embodiments, different components or modules of the lighting control system are mounted on a printed circuit board (PCB). In some embodiments, the lighting control system and different lighting fixtures may be mounted on the same PCB.
In some embodiments, the lighting control system 200 may comprise a user interface 204. The user interface 204 may be a graphical user interface (GUI), a web-based user interface (WUI), a touchscreen, a touch user interface, or other user interfaces through which a user may interact with the lighting control system 200. Via the user interface 204, a user may program how the lighting fixtures should be adjusted. In one embodiment, the lighting control system 200 comprises a one-touch button that allows a user to program lighting control instructions or commands. In other embodiments, the lighting control system 200 may comprise a remote control that facilitates a user to program lighting control instructions or commands. The remote control may communicate in various communication protocols such as Bluetooth, Zigbee, 802.11 protocols, Infrared (IR), Radio Frequency (RF), or any other wireless protocol. In some embodiments, a user may choose a color such as a specific color blend to enhance the color of a fish species or a color that reflects a mood, or to choose a location where the light source should be adjusted and how it should be adjusted.
In further embodiments, a user may also select how the lighting source should be turned on or turned off, such as the ramp-up time and intensity, the ramp-down time and intensity such as sun rise/sun set effects. In some embodiments, the user may select a color, a color combination, a dimming option, a photoperiod, or other lighting characteristics and effects. In one embodiment, the lighting control system 200 may be preloaded with a selection of lighting characteristics and effects such as commonly used lightings, which may be displayed on the user interface 204 for a user to select.

The communication module 201 is configured to receive from or to transmit instructions to various user systems. In one embodiment, the communication module 201 may comprise a network interface controller that may connect the lighting control system 200 with a communication network which may be a wired system (e.g., a coaxial cable system, a fiber optic cable system, an Ethernet cable system), or a wireless network system (e.g., a wireless personal area network, a wireless local area network, a cellular network.)
In one embodiment, the processing module is coupled to the memory 202. In various embodiments, the processing module 203 is configured to process the user's instructions, which may be stored in the memory 202. When processing the instructions, the processing module 203 may generate PWM channel control signals. The processing module 203 may further adjust the duty cycles of the Pulse Width Modulation (PWM) channels accordingly. In some embodiments, the processing module 203 only adjusts the PWM channels that have connected lighting sources. In other words, the PWM channels that have no connected lighting sources will not be adjusted and will generate NULL output. In other embodiments, the lighting control system 200 may control various devices such as lighting fixtures, audio devices, air pumps, fish feeders, decoration devices.
As illustrated in FIG. 2, the lighting control system 200 may be connected between a power source 206 and one or more lighting fixtures (1−i) 207A-207B. The power source 206 may be a power adapter that converts the alternating current (AC) from power outlets into a 12-volt or 24-volt direct current (DC). In one embodiment, when one or more lighting fixtures 207A-207B are constant-voltage supplied, the lighting control system 200 adjusts the current supplied to them by adjusting the duty cycles of the corresponding PWM channels. The light sources 208A-208F comprised in the lighting fixtures 207A-207B may be configured with a light emitting diode (LED), an organic light emitting diode (OLED), a xenon bulb, a halogen bulbs, and an electroluminescent (EL) light source (e.g., an EL panel or film), or any combination thereof.
The lighting fixtures 207A-207B may be configured with a series of identically colored light sources that allow for variable light intensity. Various embodiments of the lighting control system 200 may calibrate the intensity and resolution of each light source and adjust the duty cycles of the PWM channels accordingly. The lighting fixtures 207A-207B may also be configured with RGB lighting systems, that is a series of blue, red, and green light sources that allow for different color blends. Moreover, the lighting fixtures 207A-207B may be configured with RGBW lighting systems, that is a series of blue, red, green, and white light sources that allow for different color blends. Each of the blue, red, green, and white light sources may be associated with a PWM channel of the lighting control system 200, and the lighting control system 200 adjusts the duty cycle of each PWM channel accordingly thereby creating different combination of colors.
Further, in some embodiments, the lighting control system 200 may be coupled to an audio source 209. In one embodiment, the lighting control system 200 is coupled to the audio source 209 via an audio jack. In one embodiment, the lighting control system 200 may comprise a sound sensor (not shown). The lighting control system 200 may regulate light supplied to the lighting fixtures 207A-B according to sound signals from the audio source 209. A user may select the sensitivity setting and the lighting control system 200 may adjust the light based on the selected sensitivity setting (for example, low, medium or loud volumes.) For example, the lighting fixtures 207A-B may flash to the rhythm of medium volume of the audio source 209.

The illustrated implementation 300 comprises a transformer 301, the lighting control system 302, a fish tank 303, and lighting fixtures 304-309. Each lighting fixture may comprise a set of light sources (not shown). As illustrated, the lighting control system 302 may control multiple lighting fixtures at the same time. The lighting fixtures 304-309 may be the same or may be different. The lighting control system 302 may control the lighting fixtures 304-309 to create various lighting effects. For example, the lighting control system 302 may control the lighting fixtures 304-306 that are placed above the fish tank 303 to fade one by one from left to right. In various embodiments, the lighting control system 302 may comprise a remote control (not shown). A user may control various devices via the remote of the lighting control system 302, such as lighting fixtures, audio devices, air pumps, fish feeders, decoration devices. In one embodiment, a user may program the remote control such that each button of the remote control controls a corresponding light source or lighting fixture. The remote control may communicate with the lighting control system 302 in various communication protocols such as Bluetooth, Zigbee, 802.11 protocols, Infrared (IR), Radio Frequency (RF), or any other wireless protocol.
FIGS. 4A-4C are diagrams illustrating exemplary implementations of an example lighting control system 401 in accordance with an embodiment of the invention. As illustrated in FIGS. 4A-4C, the lighting control system 401 may be implemented in connection with a lighting fixture 402. The lighting fixture 402 may comprise an accessory light 403 that may be coupled to the lighting fixture 402 via a jack, such as a headphone jack. The accessory light 403 may be a lighting fixture such as a light strip or a spotlight. The lighting fixture 402 and the accessory light 403 each may comprise a set of light sources. The lighting control system 401 may control both the lighting fixture 402 and the accessory light 402 according to a user's instruction. The lighting control system 401 may control the lighting fixture 402 and the accessory light 403 such that the lighting fixture 402 and the accessory light 403 may work in concert with each other. For example, the accessory light 403 may be complementary to the lighting fixture 402.
As illustrated in FIG. 4A, the accessory light 403 may be submersible in the fish tank 404. The accessory light 403 may function as landscape lighting. The accessory light 403 may also be placed above the water in the fish tank 404, as illustrated in FIG. 4B. Further, the accessory light 403 may be place outside the fish tank 404, as illustrated in FIG. 4C. In the illustrated example, a background insert 406 may be placed between the wall 405 and the fish tank 404 to create a theme, for example, beaches, forests, flowers, etc. The background insert 406 may be removed and inserted into a slot (not shown). The accessory light 403 may shine on the background insert 406 or on the wall 405 when the background insert 406 is removed.
FIG. 5 is a diagram illustrating a lighting control system 504 in accordance with an embodiment of the invention. The lighting control system 504 is implemented in a lighting system 500, which comprises a 12-volt wall transformer 501, and lighting fixture 507 comprising light sources 508. The lighting fixture 507 may be configured with a series of identically colored light sources (e.g., blue light-emitting diodes) that allow for variable light intensity, or a series of blue, red, and green light sources that allow for different color patterns. In the lighting system 500, the lighting fixture 507 is configured as a flexible light-emitting diode (LED) strip.
The lighting control system 504 may be used in some embodiments to control the behavior and parameters of the light sources 508 within the lighting fixture 507. For example, the lighting control system 504 may control the color pattern, light intensity, or timing of light patterns emitted from the lighting fixture 507. Additionally, the lighting control system 504 may be configured with a stop switch (not shown), which when engaged would cause the lighting control system 504 to stop or pause the logic the lighting control system 504 is performing through the lighting fixture 507.
Some embodiments are implemented with tool-less connectors that allow for easy removal and replacement. For example, in the lighting system 500, the system is configured with a direct current (DC) jack 502 and DC receptacle 503, allowing the wall transformer 501 to be easily disconnected from the lighting control system 504 without the need for tools. Further, the lighting control system 504 may be configured with a 4-pin plug 505 and receptacle 506, which allows the lighting control system 504 and/or the lighting fixture 507 to be easily connected or disconnected.
In certain embodiments of the invention, the lighting control system may be further configured with male and/or female power connectors that allow multiple lighting control systems to be implemented together, either in parallel or in series. As illustrated in FIG. 6, each lighting control system 601 is configured with only a female DC receptacle 602, which can accept a male plug from a power supply unit 604. As such, two or more lighting control systems 601 may be connected to a single power supply unit 604 by using a splitter with male DC plugs 603.
