光控长延时LE D路灯控制器的研究与设计斯密特触发器

摘要

针对城市道路照明LED改造中半功率节电应用的特点，提出了一种基于光控和长延时开关的LED路灯控制方案，利用光敏电阻、555时基电路和CD4060二进制计数器实现了控制电路的设计；实验结果表明：本方案简单可行，实用可靠。%This paper focus on the features of half power saving in city road lighting LED retrofits,and presents a light control and time-lapse switch LED lights control scheme.Using photo resistor,555 time base circuit and CD4060 binary counter,it realizes the control circuit design.The experimental results show that the proposed scheme in this paper is simple,practical and reliable.
