    摘要： Embodiments of wave-based lighting efficiencies are provided. As an example, a method includes determining a characteristic of a voltage from an alternating current (AC) waveform, where the AC waveform is configured to power a load, and wherein the AC waveform includes positive voltage portions, negative voltage portions, and zero axis points. Some embodiments include determining a first position in the AC waveform to create a first step with a first step voltage and applying the AC waveform at the first step to a first predetermined portion of the load, where the first predetermined portion of the load has a first voltage rating that corresponds to the first step voltage.

    摘要： The disclosure is directed to a circuit that may detect a single short in a chain of loads, such as light emitting diodes (LEDs). The circuit may drive either multiple LED chains or a single LED chain to determine whether one, or more, of the LEDs in the LED chain is no longer working because of a short. The circuit determines whether the LED chain voltage satisfies a threshold based on a single LED voltage drop. Therefore, the same circuit may be used for applications regardless of the number of LEDs in an LED chain. Additionally, the circuit, according to the techniques of this disclosure may use may use no output pins, other than those used to deliver current to LED chains, regardless of the number of LED chains that the circuit drives.

    摘要： The invention provides a method and system for automatically implementing lighting control scene. The method comprises following steps: connecting the lighting control module to a scene design module, establishing a correspondence between an actual scene controlled by the lighting control module and a simulated scene designed by the scene design module, the photosensitive spots set in the actual scene are mapped to fixed light spots in the simulated scene; connecting photosensitive matrix modules that can be mounted on an indoor ceiling to the scene design module, establishing a correspondence between a sensing range map and a simulated sensing range map, so that the photosensitive spots correspond to at least one light measuring spot on the photosensitive matrix module, the simulated light measuring spots of the simulated photosensitive matrix module correspond to the light measuring spots of the photosensitive matrix modules one to one; The scene design module overlays the simulated scene with the simulated sensing range map, to associate the fixed light spots with the simulated light measuring spots, associate the fixed light spots with the light measuring spots, so that the photosensitive spots correspond to the light measuring spots. Through above steps, the scene designed and rendered by the computer can be directly transplanted to the entity lighting control system, thereby realizing the effect of designing the lighting control.
