Illumination Controller (34)

Published:2011/7/7 6:52:00 Author:Sue | Keyword: Illumination, Controller | From:SeekIC

The 220v ac voltage will provide IC with 4.7v direct current voltage after it is limited and reduced by R1,C1, stablized by VS,rectificated by VD2, filtrated by C2,R3,C3. After IC begins to work, its pin 13-16(L1-L4 terminals) will output changing trigger control signals. By controlling VT1-VT4's working states, HL1-HL4's illumination effects can be controlled. IC's pin 4 and pin 5 will output audio signals which will drive BL to make music after it is amplified by V1,V2. S is illumination modesselector button. When S is pushed, the illumination modes will be changed.
