彩灯控制电路 摘要：在日常生活、欢乐节日、娱乐及科研中，到处都会遇到装饰问题，总离不开彩灯控制器。彩灯控制电路的不断完善，使得人们的生活更加丰富多彩。本设计主要介绍彩灯控制电路的设计组成及工作原理。电路中的220V电压通过外接稳压电源件加到路彩灯的接入电源两端，当电路导通时彩灯被点亮，否则熄灭。根据技术计数指标的要求，通过大量资料的查询，并有效结合所学知识，最后确定了的一套比较合适的方案，即通过振荡电路、计数/时序分配电路这些触发信号由移位寄存器产生的顺序脉冲给出。通过分析研究，结合NEE555和CD4017集成块的功能，完成出电路设计图方案，并制作成PCB板；焊接成型后，通过检查、通电、调试完成彩灯控制电路。 关键词：彩灯控制电路，时钟脉冲，NE555，CD4017、振荡电路。 Ⅰ Colored lantern controller circuit abstract: In daily life, festivals and entertainment, and in scientific research, in almost all aspect of life people will come across some decoration problems and people can not live without colored lantern in modern time. With the improvement of colored lantern of controlling circuit, our life are becoming more and more colorful. This design mainly introduces lights control circuit design structure and working principle. Within the circuit, the external manostat voltage by 220V, adding to lantern access power ends, when the circuit conducted，the lights turn on, otherwise extinguished，till the last light and then start all over again. According to the technical requirement, through the mass of data query as well as effectively combine with the knowledge attained, the final determination of a relatively the right are shaped up. That is, these triggered signals are produced by shift register, the order of pulse, through oscillating circuit, counting/temporal distribution circuit .Through analysis, combining with the NEE555 and CD4017 integrated block’s function, the circuit design scheme completed, and have made it into PCB. After welding forming, through inspection, electricity and debugging the lights control circuit are completed. Key words Colored lantern controller; Clock pulse; NE555; CD4017; oscillating circuit. Ⅱ 前言 随着人们生活环境的不断改善和美化，在许多场合可以看到彩色霓虹灯。由于其丰富的灯光色彩，低廉的造价以及控制简单等特点而得到了广泛的应用，用彩灯来装饰街道和城市建筑物已经成为一种时尚。 此次课程设计的彩
