  • Patent number: 10660181
    Abstract: A controllable silicon light regulation apparatus without a driving power element receives an alternating current (AC) from an AC source comprising a first light emitting diode (LED) source module and a second LED source module. The controllable silicon light regulation apparatus stores specified color temperatures. A difference between adjacent specified color temperatures is 100K. Under a segment dimming mode, the controllable silicon light regulation apparatus sets a segment value and selects a number of the specified color temperatures based on the segment value. A color temperature of the controllable silicon light regulation apparatus is gradually regulated in a loop of target color temperatures based on a counted number of turn-on times in a specified time duration of the AC source.
