A system for emitting light (such as a luminaire) includes a first light emitting diode (LED) string and a first LED driver that is electrically connected in parallel to the first LED string. The system also may include a second (or more) LED string(s), each associated with an additional LED driver. One-way conductors and normally-open switches are used so that if one LED driver fails, the remaining LED driver(s) will deliver power to the failed driver's LED string so that the light remains operational, but with a reduced brightness.

Shared power topology for LED luminaires

A system of networked lighting devices includes a group of lighting device fixture controllers connected in a communication chain. The communication chain provides for transfer of data packets between the lighting device fixture controllers and a central controller. Each fixture controller includes a first power input that receives power from a primary power source, and a priority switch that is configured to switch the fixture controller from the primary power source to a source of DC power upon detecting failure of the primary power source. The source of DC power is sufficient to power the fixture controller and enable the fixture controller to continue to pass a stream of data to other controllers in the communication chain, but it is not sufficient to power the fixture controller's associated lighting device.

Control system for lighting devices

A lighting device includes multiple light emitting diode (LED) channels. Each LED channel is connected in parallel to an output rail of a power converter. The power converter may be a buck regulator. Each LED channel may include an LED string of one or more LEDs, a first transistor that is electrically connected between the LED string and ground, a second transistor that is electrically connected between the first transistor and ground, and a current sensing resistor that is electrically connected between the first transistor and the second transistor. This design provides for self-regulation of current across all LED channels when another LED channel is added to or deleted from the lighting device.

LED luminaire with constant current per-module control

A lighting system includes a lighting device that further includes a housing, and light emitting diode (LED) modules positioned in an opening of the housing to emit light away from the housing. Each LED module includes a substrate, a plurality of module-level conductors, and a plurality of LED sets, each of which comprises a first section including a first group of LEDs, one or more additional sections (each including an additional group of LEDs), a first conductive element that electrically connects the first section to a first one of the module-level conductors, and one or more additional conductive elements. The lighting system also includes a sensor and a control circuitry configured to generate commands to control drive currents delivered to the first group of LEDs in each LED set and each additional group of LEDs in each LED set based on the data collected by the sensor.

Lighting device LED module with effects for color temperature tuning and color tuning

A lighting system includes a lighting device that further includes a housing, and light emitting diode (LED) modules positioned in an opening of the housing to emit light away from the housing. Each LED module includes a substrate, a plurality of module-level conductors, and a plurality of LED sets, each of which comprises a first section including a first group of LEDs, one or more additional sections (each including an additional group of LEDs), a first conductive element that electrically connects the first section to a first one of the module-level conductors, and one or more additional conductive elements. The lighting system also includes control circuitry configured to generate commands to control drive currents delivered to a first group of LEDs in each LED set and each additional group of LEDs in each LED set so that the lighting device emits light of a specified color temperature.

A lighting device includes one or more LED modules, each of which includes a group of LED sets positioned on a substrate. Each LED set includes two or more sections, optionally under a single lens. The sections are individually controlled by a controller of the lighting device or an external controller. The beam spread, beam shape, or both of the light emitted by the device may be controlled by selectively activating the sections of each LED set.

Lighting device LED module with effects for beam spread tuning and beam shaping

A lighting device includes one or more LED modules, each of which includes a group of LED sets positioned on a substrate. Each LED set includes two or more sections, optionally under a single lens. Each section is configured to emit light of different luminescent properties, such as different colors or different color temperatures. The color, color temperature or other characteristics of light emitted by the device is controlled by selectively activating the sections of each LED set.

A system of networked lighting devices includes a central controller and a group of lighting devices. The central controller includes a processor, first and second communication interfaces, various lighting devices and a communication link. The first communication interface includes input ports and a multiplexer configured to receive signals from the input ports and combine the received signals into a multiplexed signal. The second communication interface includes one or more antennas and is configured to receive the multiplexed signal from the multiplexer and transmit the multiplexed signal via the antenna(s). Each lighting device includes a fixture controller, one or more lighting modules, and a communication interface. The communication link transmits the multiplexed signal between one or more of the lighting devices and at least one of the communication interfaces of the central controller.

A system of networked lighting devices includes a central controller and a group of lighting devices. Each lighting device may include a fixture controller, one or more lighting modules, and a communication interface. The central controller receives data packets and send them to the lighting devices via a ring topology. The lighting devices may be connected to each other via the ring topology, or a set of routers may be connected in the ring topology, with each router controlling one or more connected lighting devices. The central controller and/or the fixture controllers may each translate data packets from one protocol to a different protocol. The different protocol may be a protocol that is compatible with the local system of networked devices, and/or a protocol that is compatible with the lighting device(s) that will use the data packets to actuate according to a command from the central controller.

Controllers for interconnected lighting devices

A lighting control system includes a control card for an illumination device. The control card receives an input signal from a controller electronic device, identifies a type of the illumination device, and uses the identified type to identify an output signal protocol corresponding to the illumination device. If the input signal uses a protocol that differs from that of the output signal protocol, the control card will convert the input signal to the output signal protocol. The controller device may be programmed to enable a user to display and/or control various parameters of various lighting devices.
