The 220v ac working voltage will provide IC and audio amplifier circuit with 4.5-4.7v direct current working voltage after it is limited and reduced by R1,C1, stablized by VS, rectificated by VD2, filtrated by C2. After IC begins to work, its pin 7(audio signals output terminal) will output audio signals which will drive BL to make music after it is amplified by audio power amplifier circuit. IC's pin 10-13(L1-14 terminals) will output trigger control signals whichwill change with audio signals. By changing the working states of VT1-VT4, HL1-HL4's illumination effects can be changed. S1 is illumination modesselector button. When S1 is pushed, illumination mode can be changed. When S1 is pushed continuously, the 7 illumination modes can be changed circularly. S2 is volume control button. When S2 is pushed continuously, BL's volume can be changed as the order of HIGH-MEDIUM-LOW-NONE-HIGH .
