Illumination Controller (28)

Published:2011/7/7 5:53:00 Author:Sue | Keyword: Illumination, Controller | From:SeekIC

The 220v ac voltage will provide IC with 4.5v direct current working voltage after it is rectificated by VD1-VD4, limited and reduced by R3, stablized by VS, filtrated by C. The other circuit will provide IC's pin 1 with ac synchronizing signal through R1. After IC begins to work, its pin 3-6(L1-M terminals) will output trigger control signals.By controlling the working states of VT1-VW, HL1-KH will change the illumination modes automatically. S is manual control button. By pushing S, illumination modes can be choosed manually.
