摘要: Circuitry, which is compatible with incandescent light dimmers, disposed within the screwbase of a compact fluorescent light, and sets driving frequencies for mercury plasma, based, at least in part, on sensing duty cycle incoming AC supply waveform. In this way, existing lighting infrastructure, including phase-cut dimmer circuits bulbs, may be preserved, bulbs can replaced lights equipped circuitry accordance present invention. further aspect, synchronizes bulb drive signals power line frequency.
