A lighting fixture includes a light source, a housing coupled to the light source, communications circuitry, and control circuitry. The housing includes an opening through which light from the light source is provided. The control circuitry includes a memory storing instructions, which, when executed by the control circuitry cause the lighting fixture to adjust one or more light output parameters of the light source, and store fixture location information describing a location of the lighting fixture in response to receipt of the fixture location information from the communications circuitry. By storing fixture location information describing the location of the lighting fixture, the location of the lighting fixture may be used to send messages to lighting fixtures in the same location and/or retrieve data from lighting fixtures in the same location, which may be beneficial in many circumstances.

An air conditioner is provided that may include a setting unit to set a predetermined function to be embodied or displayed with lighting, a storing unit to store at least one illumination pattern information, a control unit to connect the function input by the setting unit to an illumination pattern stored in the storing unit, and a lighting unit to be lighted according to the illumination pattern information connected to the function by the control unit.

Processes for commissioning an indoor lighting system composed of a plurality of lighting fixtures, each including a lighting associate, include the steps of establishing a direct connection table for each lighting associate; forming a full direct connection table represented as a square matrix and comprising data derived from all direct connection tables; grouping the lighting associates using an element reduction operation on the square matrix; and transmitting a group direct connection matrix to each lighting associate. The lighting fixtures may include a first transmitter for transmitting a first message to a second lighting associate; a first receiver for receiving a second message from the second lighting associate; a second transmitter for transmitting a third message via a lighting associate support network; a second receiver for receiving a fourth message via the lighting associate support network; an interval timer; a microcontroller in communication with the interval timer, programmable to execute a networking and communication algorithm to process the first, second, third, and fourth messages; an LED lamp; and a switch between the lamp and a power line, controllable by the microcontroller.

A load control device for controlling the amount of power delivered to an electrical load may include a rectifier circuit configured to receive a phase-control voltage and produce a rectified voltage. A power converter may be configured to receive the rectified voltage at an input and generate a bus voltage. An input capacitor may be coupled across the input of the power converter. The input capacitor may be adapted to charge when the magnitude of the phase control voltage is approximately zero volts. The power converter may be configured to operate in a boost mode, such that the magnitude of the bus voltage is greater than a peak magnitude of the input voltage. The power converter may be configured to operate in a buck mode to charge the input capacitor from the bus voltage when the magnitude of the phase-control voltage is approximately zero volts.

A lighting fixture having a light source, a light sensor, a communication interface, and circuitry is described. In addition to controlling the light source, the circuitry is adapted to monitor for a light signal provided from a handheld device via the light sensor; upon receiving the light signal, measure a signal level associated with the light signal; and effect transmission of the signal level to the handheld device via the communication interface. In one embodiment, the circuitry is further configured to receive an instruction to monitor for the light signal from the handheld device via the communication interface such that the circuitry begins monitoring for the light signal upon receiving the instruction.

A method of controlling illumination, including transmitting location information from a communication device to a computer; receiving illumination data with the communication device, where the illumination data is generated by the computer based at least in part on the location information; and transmitting an illumination signal from the communication device to a wearable accessory containing at least one light source, where the illumination signal is based at least in part on the received illumination data and is operable to actuate the at least one light source.

A light system for a vehicle using an eight-zone controller for controlling the lights. The eight-zone controller can maintain eight independent signal zones, or two or more zones can be grouped together. The eight-zone controller is configured with splitter hubs and second tier splitter hubs to increase the quantity of lights included in the system.

A connected lighting system that includes a substrate defining a broad face, a first set of light emitting elements, and a second set of light emitting elements. Each light emitting element of the second set of light elements may be configured to emit light having a fixed color parameter different from a first color parameter of the first set of lighting elements. The first and second sets of light emitting elements may be arranged at at least two different contiguous portions of the broad face of the substrate. A processor may be configured to control the first set of light emitting elements with a predetermined intensity and control relative intensities of one or more of the second set of light emitting elements to cooperatively emit light having a first color parameter value.

A method of determining the position of an array of sensors, an array of solid-state lamps, or other devices which sense or emit electromagnetic waves includes first determining a sensing or emitting distribution for one of the devices, then integrating that distribution over the area to be covered by the sensors or emitters. In response to the integrated distribution, the sensors or emitters may be repositioned, reconfigured, or reoriented to provide desired coverage. Wireless access points that communicate to wireless end points associated with the lights and/or sensors are designed and positioned to provide adequate signal strength. All elements, light distribution, sensor range, and wireless signal strength may be plotted in contour plots within the same user interface that enables users to place the devices in a specified area.

A mechanism for control and configuration of a lighting system from a user interface. For instance, a wall module designed as a user interface for a tenant to control the system may be implemented so as to be used not only to control the lighting system but also to configure it. The lighting system may involve a controller, circuits of lights, relays, motion and ambient detectors, scenes, schedules, and more. An additional user interface such as a wall module may be connected to the lighting system for control and configuration of the system.
