The circuit is as shown. It consists of clock beat generator, light control circuit, laughing phonation circuit and AC depressurization rectifier circuit. SH-804 is a CMOS color lamp program control special integrated circuit, it has ten kinds of circulation transform ways and six kinds of dimming light change speed such as up slowly fading, horse racing, jumping, smooth water, pour water, waves rolling, starsflashing and all brightness. The transform ways can automatically cycle changing, it also can artificial set flashing patterns through key terminal. This circuit adopts clock pulse automatic key way , to achieve the flashing patterns' automatic changing. F1~F4 is four 2 input terminal Nand, CMOS is IC CD4011, the F1, F2 and R2, C1 form a low frequency clock generator, the clock frequency is:
