摘要： A method for controlling an amount of power delivered to an electrical load may include controlling an average magnitude of a load current towards a target load current that ranges from a maximum-rated current to a minimum-rated current in a normal mode and controlling the average magnitude of the load current below the minimum-rated current in a burst mode. The burst mode may include at least one burst-mode period that comprises a first time period associated with an active state and a second time period associated with an inactive state. During the burst mode, the method may include regulating a peak magnitude of the load current towards the minimum-rated current during the active state and stopping the generation of at least one drive signal during the inactive state to control the average magnitude of the load current to be less than the minimum-rated current.

摘要： The present disclosure relates to a dimmable LED lamp illumination system. The dimmable LED lamp illumination system includes: a dimmer and an LED lamp. The dimmer is connected in series between a power input end and the LED lamp, and is used for loading a digital dimming signal onto a power signal, so as to generate a dimming power signal. The LED lamp receives the dimming power signal, demodulates the digital dimming signal, and adjusts the brightness of the LED lamp based on the demodulated digital dimming signal. By using the dimmable LED lamp illumination system of the present disclosure, the deployment of a dimming system is simpler, and the transmission of a digital dimming signal is more stable.

摘要： A multiple location load control system comprises a main device and remote devices, which do not require neutral connections, but allow for visual and audible feedback at the main device and the remote devices. The main device and the remote devices are adapted to be coupled together via an accessory wiring. The main device can be wired on the line side and the load side of the load control system. The main device is configured to enable a charging path to allow the remote devices to charge power supplies through the accessory wiring during a first time period of a half cycle of the AC power source. The main device and the remote devices are configured to communicate with each other via the accessory wiring during a second time period of the half cycle, for example, by actively pulling-up and actively pulling-down the accessory wiring to communicate using tri-state logic.

摘要： Systems, apparatus and methods for selectively activating and/or deactivating one or more groups of light-emitting diodes (LEDs) of a luminaire. In an embodiment, a multi-LED luminaire includes a detection and control circuit, a first light emitting diode (LED) Group, a second LED Group connected in series to the first LED Group, and a first switch operably connected across the second LED Group. The detection and control circuit detects either a power sequence or a dimming sequence and, in response to detection of the power sequence or to the dimming sequence, operates to close the first switch to short-out the second LED Group such that no light is emitted from the second LED Group, operate to open the first switch to power the second LED Group to emit light along with the first LED Group, or operate the switch in a manner to alter the light output of at least one of the first LED Group and the second LED Group.

摘要： A method of increasing the color gamut of a multi-emitter light emitting device when dimming includes the steps of independently driving each emitter in the device, and increasing the lumen output of at least one emitter while simultaneously decreasing the lumen output of at least one other emitter, such that total color gamut increases while total lumen output of the light emitting device decreases. A light emitting device is also disclosed.

摘要： An LED light tube includes a glass tube, end caps, an LED light strip, LED light sources, and a power supply module. The end caps are respectively attached at two ends of the glass tube. The LED light strip is attached to an inner circumferential surface of the glass tube. The LED light sources are mounted on the LED light strip. The power supply module is electrically connected to the LED light strip. Each of the end caps includes a lateral wall and an end wall. The lateral wall is substantially coaxial with the glass tube and connected to the glass tube. The end wall is substantially perpendicular to an axial direction of the lateral wall and connected to an end of the lateral wall away from the glass tube. The power supply module includes a rectifying circuit and a filtering circuit electrically connected to the rectifying circuit.

摘要： A lighting fixture incorporates a peripheral light emission feature, such as a peripheral waveguide and/or a peripheral reflector region. A peripheral light emission feature may at least partially surround a non-peripheral feature that may include a light-transmissive panel. At least one first light source may illuminate a peripheral light emission feature, and at least one second light source may illuminate a light transmissive panel. Control circuitry is configured to selectively adjust intensity and/or color temperature of the light sources to cause aggregate emissions of the lighting fixture (or a lighting system with multiple lighting fixtures) to dynamically change over time (e.g., with different intensities and color temperature), so as resemble a skylight or window. A viewer may thereby perceive at least portions of a space as being naturally illuminated.

摘要： A multi-function vehicle lamp having a plurality of light emitting diodes includes a turn input and a tail input with a switch configured to stop current flowing through the tail input when the turn input is energized to increase current flow through the turn input to satisfy minimum current draw requirements of a vehicle current meter that detects turn indicator failure. The lamp may include a single combined turn/stop input, or may include separate turn and stop inputs. Lamps having separate turn and stop inputs block current flow through the stop input when the turn input is energized.
