Light fixtures are, generally, hard-wired directly to light controllers. However, due to the limited ability to retrofit wires in a building, the hard-wired connections are challenging, if not impossible, to re-configure in real-time. In some installations, the light fixtures are wirelessly connected to light controllers. However, due to the number of light fixtures in a typical building, the wireless connections between individual light fixtures can cause wireless communication collisions and increased latency, thereby causing delays in a light fixture's response to a control input. Thus, a need exists in the art for improved wireless light controller processes and apparatuses for a light system with the features as described herein.
As a general overview of wireless light controller processes and apparatuses for a light system (hereinafter referred to as “technology”), the technology includes a wireless light controller that communicates with one or more individually controllable lights via power line communication over a power line and communicates with a wireless device via wireless communications. For example, a wireless controller (e.g., mobile phone, personal computing device, etc.) transmits a wireless communication including an instruction to change a color temperature for lights A-G. The wireless light controller receives the wireless communication and converts the wireless communication to a power line communication with the instruction to change the color temperature for lights A-G. The power line communication can include the individual addresses for lights A-G to direct the power line communication to the correct lights. The lights A-G receive the power line communication and respond to the instruction to change the color temperature of the light A-G. In this regard, the wireless light controller can advantageously enable the conversion of wireless communication (in this example, an inherently fast protocol with a high bandwidth capacity with quality control features) to power line communication (in this example, an inherently slow protocol with a low bandwidth capacity with limited quality control features), thereby increasing the available uses for light fixtures and decreasing the installation time for light systems.

The wireless light controller systems and methods described herein (hereinafter “technology”) can provide one or more of the following advantages. An advantage of the technology is that the use of a wireless device with the power line communication in an existing electrical infrastructure decreases the installation cost of technology, thereby increasing the effective uses of the technology. Another advantage of the technology is that the use of the wireless device with the power line communication increases the user's flexibility and/or range for configuring lights while reducing the installation cost (e.g., reduced cable cost, reduced labor cost, etc.), thereby increasing the effective uses of the technology (e.g., use in retrofits of existing buildings, use in remodels of existing buildings, use in new construction, etc.).
The foregoing and other objects, features and advantages will be apparent from the following more particular description of the embodiments, as illustrated in the accompanying drawings in which like reference characters refer to the same parts throughout the different views. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the embodiments.
As a general overview of wireless light controller processes and apparatuses for a light emitting diode (LED) light system (hereinafter referred to as “technology”), the technology includes a wireless light controller that communicates with one or more individually controllable LEDS lights via power line communication over a power line and communicates with a wireless device via wireless communications. For example, a wireless controller (e.g., mobile phone, personal computing device, etc.) transmits a wireless communication including an instruction to change a color temperature for LED lights A-G.
The wireless light controller receives the wireless communication and converts the wireless communication to a power line communication with the instruction to change the color temperature for LED lights A-G. The power line communication can include the individual addresses for LED lights A-G to direct the power line communication to the correct lights to change the color temperature (e.g., change the color temperature of the lights to 2700 Kelvin, change the color temperature to 4500 Kelvin, change the color temperature to 6000 Kelvin, etc.). The LED lights A-G receive the power line communication and respond to the instruction to change the color temperature. In this regard, the wireless light controller can advantageously enable the conversion of wireless communication (in this example, an inherently fast protocol with a high bandwidth capacity with particular quality control features) to power line communication (in this example, an inherently slow protocol with a low bandwidth capacity with other types of quality control features), thereby increasing the available uses for light fixtures and decreasing the installation time for light systems.
Another advantage of the technology is that the transition between wireless communication and power line communication is transparent to the end user controlling the light systems, thereby decreasing configuration time and increasing customer satisfaction with the configuration of the light system. Another advantage of the technology is that the conversion between wireless communication and power line communication advantageously bridges communication between two different types of communication techniques, thereby increasing the usability of the portable configuration functionality of the technology.
In operation, the wireless device 100 communicates with the wireless light controllers 120, 130, and 140 via wireless communication 115, 116, and 117, respectively (e.g., 802.11 protocol, wireless mesh network, wireless network, cellular network, etc.). The wireless light controllers 120, 130, and 140 convert (e.g., embed the instructions in power line communication, extract the instructions from the wireless communication and generate a power line communication, etc.) the wireless communication 115, 116, and 117 to power line communication 122, 132, and 142, respectively. The conversion of the wireless communication into power line communication advantageously enables the integration of portable, handheld control of lights into existing power line control infrastructure, thereby reducing the maintenance and control costs for a light system. The conversion of the wireless communication into power line communication advantageously increases the flexibility of the light system by enabling portable, handheld control of the lights using existing power line control infrastructure.
The wireless light controllers 120, 130, and 140 communicate the power line communication 122, 132, and 142 (e.g., amplitude modulation, digital power line carrier, pulse-position modulation, etc.) to the lights A 124, B 124b through Z 124z, 134, and 144, respectively. The wireless light controller 120 transmits the power line communication 122 to the lights A 124a, B 124b through Z 124z. The wireless light controller 130 transmits the power line communication 132 to the light 134. The wireless light controller 140 transmits the power line communication 142 to the light 144.
In other examples, the conversion between wireless communication and power line communication can include identification of the instructions within the wireless communication, identification of the addresses for the lights being controlled by the instructions within the wireless communication, and generation of the power line communication based on the instructions, addresses, and/or protocol information associated with the power line communication (e.g., amplitude format, quality control requirements, etc.). In some examples, the conversation between wireless communication and power line communication further includes receiving a plurality of wireless packets and determining when the instructions for particular lights are complete (e.g., all of the wireless packets that include instructions have been received, enough of the wireless packets have been received to generate the power line communication, etc.).
In some examples, the lights A 124, B 124b through Z 124z, 134, and 144 communicate power line communication 122, 132, and 142 to the wireless light controllers 120, 130, and 140, respectively. The wireless light controllers 120, 130, and 140 can convert the power line communication 122, 132, and 142 to wireless communication 115, 116, and 117, respectively, and communicate the wireless communication 115, 116, and 117 to the wireless device 110. The wireless device 110 can display and/or provide feedback of the power line communication to the operator 105.
In other examples, the conversion between power line communication and wireless communication can include identification of the instructions within the power line communication, identification of the addresses for the lights being controlled by the instructions within the power line communication, and generation of the wireless communication based on the instructions, addresses, and/or protocol information associated with the wireless communication (e.g., packet format, quality control requirements, etc.). In other examples, the conversation between power line communication and wireless communication further includes receiving a plurality of power line packets and determining when the instructions for particular lights are complete (e.g., all of the power line packets that include instructions have been received, enough of the power line packets have been received to generate the wireless communication, etc.).
In other examples, the lights A 124, B 124b through Z 124z, 134, and 144 are individually addressable for control of the lights. The individual control of one or more of the lights advantageously enables the operator 105 and/or the wireless device 110 to control a subset of the lights via a portable, handheld device. In some examples, the wireless light controller 120, 130, or 140 transmits the power line communication 122, 132, or 142 to a light in the one or more lights based on a light address associated with the light. In other words, the individualized addressing of the lights enables the wireless light controllers 120 to focus control activities on the lights that are being controlled by the instructions.
In some examples, the instructions to control the one or more lights include one or more addresses for individual lights in the one or more lights. The wireless device 110 can include the addresses for the individual lights in the wireless communication 115, 116, or 117. The wireless light controller 120, 130, or 140 can identify the addresses for the individual lights in the wireless communication 115, 116, or 117 and can include the addresses for the individual lights in the power line communication 122, 132, or 142. In other words, the power line communication 122, 132, or 142 can include individual addresses for a subset of the lights for individualized control of the particular lights (e.g., reduce the intensity of half of the lights, change the color temperature for every third light in a light array, etc.).
In other examples, the instructions to control the one or more lights include a color temperature instruction for at least one of the one or more lights. In some examples, the color temperature instruction includes individual intensity instructions for one or more color temperature light emitting diodes (LEDs) in the one or more lights.
In other examples, the wireless communication includes any type of network protocol (e.g., wifi, code division multiple access (CDMA), time-division multiplexing (TDM), etc.). For example, the wireless communication is in a transmission control protocol (TCP)/internet protocol (IP). In this example, the wireless light controller converts the TCP/IP wireless communication into a carrier wave modulation power line communication. Table 1 illustrates exemplary conversions between wireless communication and power line communication.
Although
In this example, the wireless packets 215 are a fast protocol (e.g., 1.5 megabytes per second, 100 megabytes per second, etc.) and the power line communication 225 is a slow protocol (e.g., 570 kilobits per second, 200 kilobits per second, etc.). In other words, the wireless light controller 220 converts an inherently fast protocol with particular types of quality control characteristics (e.g., error control, transmission control, active acknowledgment of receipt, etc.) to an inherently slow protocol with limited quality control characteristics (e.g., multiple re-sends to avoid lost packets, passive acknowledge of receipt, etc.). The technology can advantageously handle both types of quality control characteristics (i.e., the quality control characteristics of the wireless communication and the quality control characteristics of the power line communication), thereby reducing communication losses associated with wireless communication (e.g., packet collisions, channel latency, etc.) and power line communication (e.g., electrical interference, magnetic interference, etc.). The wireless light controller 220 can remove the quality control characteristics and/or insert other types of quality control characteristics to the power line communication. The conversion between a fast protocol and a slow protocol advantageously enables the technology to utilize existing technology (e.g., power lines, light systems, etc.) with portable control techniques (e.g., wireless device communicating via wireless communication, an operator walking around an art museum adjusting light intensities, etc.).
For example, the wireless light controller 220 receives TCP/IP packets from the wireless device 210 and acknowledges receipt of the TCP/IP packets to ensure quality control of the communication. In this example, after receiving the TCP/IP packets, the wireless light controller 220 determines the instructions to control the light fixture 230 and generates a power line communication (e.g., a set of amplitude modulations for the instructions, a digital modulation for the instructions, etc.). The generated power line communication includes the instructions to control the light fixture 230.
In some examples, the light fixture 230 transmits the power line communication 225 to the wireless light controller 220. The wireless light controller 220 converts the power line communication 225 to the wireless packets 215 and transmits the wireless packets 215 to the wireless device 210. In this example, the power line communication 225 and the wireless packets 215 include instructions which include status information for the light fixture 230. For example, the status information includes that the lights are at 50% intensity and are running at 87 degrees Celsius. As another example, the status information includes that the lights are at 78% operational life expectancy.
For example, the wireless light controller 220 receives a wireless communication (in this example, a set of attached resource computer network (arcnet) packets) from the wireless controller 210. The wireless light controller 220 identifies a DMX512 instruction within the wireless communication by analyzing the packet headers of the wireless communication. In this example, the wireless light controller 220 identifies a DMX512 “Start Code” in the wireless communication.
As another example, the wireless light controller 220 receives a wireless communication (in this example, a set of TCPI/IP packets) from the wireless controller 210. The wireless light controller 220 identifies a remote device management (RDM) instruction within the wireless communication by analyzing the packet format of the wireless communication. In this example, the wireless light controller 220 identifies a universe of the RDM protocol from the wireless communication. The wireless light controller 220 utilizes the identified universe during the conversion of the wireless communication to the power line communication (in other words, the power line communication is directed to the appropriate lights within the universe).
In some examples, the wireless light controller 220 stores, via a storage device, a plurality of wireless communication and/or power line communication. The wireless light controller 220 can group instructions for a light, a set of lights, and/or lights associated with a power line together to reduce the communication overhead associated with establishing a communication channel (e.g., wireless communication channel, power line communication channel, etc.). In other examples, the wireless light controller 220 receives an instruction for a set of lights A and holds the instruction for the set of lights A for a set time period (e.g., 10 milliseconds, 1 second, etc.), a dynamic time period (e.g., average time period between instructions, time from last instruction, etc.) and/or any other type of parameter (e.g., predetermined number of instructions, predetermined number of lights being addressed by the instructions, dynamic percentage of lights being addressed, etc.). For example, the wireless light controller 220 receives five instructions for a set of lights B via wireless communication, groups the five instructions together (e.g., one packet with all five instructions, two packets with the five instructions split between the two packets, etc.), and transmits the grouped instructions to the set of lights via power line communication.
The wireless transceiver 322 receives wireless communication from a wireless controller. The wireless communication includes instructions for control of one or more lights. The power line transceiver 324 transmits power line communication to the one or more lights. The power line communication includes the instructions to control the one or more lights.
The light instruction module 326 identifies an instruction to control of the one or more lights in the wireless communication and generates the power line communication based on the instruction to control the one or more lights. In some examples, the light instruction module is further configured to identify another instruction to control the one or more lights in the power line communication and generate the wireless communication based on the other instruction to control the one or more lights.
In other examples, the light instruction module identifies another instruction in the power line communication. The other instruction includes status information for the one or more lights. In some examples, the light instruction module generates the wireless communication based on the other instruction.
In some examples, the instructions to control the one or more lights include a color temperature instruction for the one or more lights. In other examples, the color temperature instruction includes individual intensity instructions for one or more color temperature light emitting diodes (LEDs) in the one or more lights. In some examples, the status information includes usage information (e.g., 1134 hours of usage, 45 kilowatts of power used, etc.), temperature information (e.g., operating between 65-75 degrees Celsius, highest operating temperature of 78 degrees Celsius, etc.), expected life information (e.g., 34 hours of usage remaining, 56 days of usage remaining, etc.), and/or color temperature information (e.g., current color temperature setting, previous five color temperature settings, etc.).
The processor 394 executes the operating system and/or any other computer executable instructions for the wireless light controller 320 (e.g., executes applications). The storage device 395 stores light information and/or control information (e.g., light fixture serial number, light fixture address, light fixture usage, etc.). The storage device 395 can include a plurality of storage devices and/or the wireless light controller 320 can include a plurality of storage devices (e.g., a protocol storage device, an instruction storage device). The storage device 395 can include, for example, long-term storage (e.g., a hard drive, a tape storage device, flash memory), short-term storage (e.g., a random access memory, a graphics memory), and/or any other type of computer readable storage.
In some examples, the instructions to control the one or more lights include one or more addresses for individual lights in the one or more lights. In other examples, the wireless light controller 220 transmits (435) the power line communication to a particular light in the light fixture 420 based on a light address associated with the light. The addressing of a particular light advantageously enables the technology to reduce energy consumption and decrease maintenance costs by focusing the control of the lights on particular lights (e.g., light focused on a particular art work, lights outlining a door, etc.).
In some examples, the wireless light controller 220 identifies (550) a second instruction to control the one or more lights in the power line communication. The wireless light controller generates (560) the wireless communication based on the second instruction to control the one or more lights.
