摘要： A circuit arrangement for controlling a plurality of loads of an electrical appliance has a main control module, arranged in a first voltage range and configured to generate control data for controlling a plurality of loads, which are arranged in a second voltage range. A galvanic isolation unit transfers the control data via a galvanically isolated connection from the first voltage range to the second voltage range. At least one auxiliary control module has a plurality of control outputs for the loads and an LED driver for operating a corresponding plurality of LED arrangements via the of control outputs, and/or a general-purpose input/output expansion circuit with programmable control outputs. Based on the control data, the auxiliary control module identifies a first control output for controlling the first load and causes the first load to be controlled via the first control output.

The first branch includes multiple first LED modules. The multiple first LED modules are divided into multiple first segments. There are first nodes between adjacent first segments. The second branch includes multiple second LED modules. The multiple second LED modules are divided into multiple second segments. There are second nodes between adjacent second segments. The switch control unit is used for controlling selections of the first switch, the second switch and the multiple middle switches for determining a conductive path of a selected set of LED modules selected from the multiple first segments and the multiple second segments for mixing a required optical parameter.

摘要： A lighting apparatus includes a solar plate, a battery, a driver module, a light source, a lens tube, a main housing and a plugging bar. The solar plate converts a sunlight to an electricity. The battery stores the electricity. The driver module converts the electricity stored in the battery to a driving current. The solar plate is placed on a top side of the driver module and the light source is placed on a bottom side of the driver module. The lens tube has a top opening and a bottom opening. The top opening has a larger size than the bottom opening. The top opening is closer to the light source than the bottom opening. A light of the light source is emitted via a lateral lens surface of the lens tube between the top opening and the bottom opening.

摘要： A configurable controllable under cabinet lighting fixture and system for controlling the same are provided. An example configurable controllable under cabinet lighting fixture includes one or more lighting elements positioned from a proximal end of a lighting fixture housing to a distal end of a lighting fixture housing. The example configurable controllable under cabinet lighting fixture further includes circuitry configured to control one or more first parameters associated with the one or more lighting elements. The circuitry is further configured to control one or more second parameters associated with one or more nearby configurable controllable under cabinet lighting fixtures located within a proximity threshold of the configurable controllable under cabinet lighting fixture. The lighting fixture housing is configured for affixing to a downward facing surface of a mounting surface.

摘要： Discussed herein are systems, devices, methods, and computer-readable media for reducing a number of undriven or underdriven uLEDs of a uLED die. A method can include identifying, by a controller of a micro light emitting diode (uLED) die, a dynamic series resistance (Rd) or forward voltage (Vf) of a uLED of the uLED die, selecting, by the controller and based on the identified Rd or Vf, a current level (IPWM_0) less than a maximum current level (IPWM_MAX) supplied by a uLED driver coupled to the uLED die, and causing, by the controller, current, at the selected current level, to be supplied to the uLED driver.

摘要： The present invention discloses a method, device, terminal setting and readable storage medium for correcting mixed color. The method first acquiring color coordinates of standard mixed color and color coordinates of mixed color to be corrected, when the first difference coordinates of the two color coordinates exceed preset threshold, calculating a ratio of Y coordinate and X coordinate of the first difference coordinates to obtain first ratio, calculating coordinates difference between the first color coordinates and color coordinates of each monochromatic light to obtain difference coordinates to be processed, calculating ratios of Y coordinate and X coordinate of each difference coordinates to be processed to obtain ratios to be processed, selecting monochromatic light corresponding to a ratio to be processed with the smallest difference from the first ratio as monochromatic light to be adjusted, then realizing color correction by adjusting color channel value of the monochromatic light to be adjusted.

摘要： Techniques are described for controlling a sensing state of a device. In an example, a controller of the device stores, in a memory of the controller, first state data indicating a state of a sensor, the state being enabled. The controller, receives first input data indicating a request to disable the sensor. The controller determines that the sensor is enabled based at least in part on the first state data. Further, the controller causes the sensor to be disabled and stores, in the memory, second state data indicating that the sensor is disabled. The controller sends, to a processor, first output data indicating that the sensor is disabled.
