The colored lantern control circuit39。s unceasing consummation, causes people39。s life to be more richly colorful. This topic mainly introduces the colored lantern cyclic control electric circuit39。s design position and the principle of work. In electric circuit39。s 220V voltage adds through the siliconcontrolled rectifier ponent to each group colored lantern39。s both sides, when siliconcontrolled rectifier break over the colored lantern is lightened, otherwise extinguishes. Siliconcontrolled rectifier39。s break over or not is by its control whether extremely to join the trigger pip to decide. 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 unceasing input, shift register39。s various outports bees (low) the level high in turn, forms the sequential control signal. 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). Key words Colored lantern controller。 Clock pulse。 The circulation demonstrated。 Siliconcontrolled rectifier 哈爾濱工業(yè)大學華德應用技術學院本科畢業(yè)設計（論文） III 目 錄 摘要 .........................................................................................................
