The sequential control signal sends in the siliconcontrolled rectifier after the driving circuit, causes the siliconcontrolled rectifier in turn break over, therefore various colored lanterns are lightened in turn (extinguishment).

These trigger pip the smooth pulse which produces by the shift register gives. The oscillating circuit produces the clock pulse sends in the shift register, along with clock pulse39。s 220V voltage adds through the siliconcontrolled rectifier ponent to each group colored lantern39。s life to be more richly colorful.
