资料介绍

针对不同环境下对路灯照明亮度要求不同,设计了太阳能电池与蓄电池供电的白光LED路灯测控电路,具有光控、延时熄灭、延时后低功率输出3种照明控制模式。系统由光电池作为光敏检测元件实现亮度检测,通过单片机完成定时和可调PWM功率输出、实现路灯延时熄灭或延时后低功率照明,采用VMOS管驱动LED路灯。实验表明系统实现了光控模式时,路灯白天熄灭、晚上自动点亮;延时熄灭模式时,路灯晚上自动亮并经过设定的延时后自动熄灭;延时加低功率模式时,路灯晚上自动点亮,经延时后自动改为低功率照明控制功能,并具有蓄电池欠压和过压保护功能。

According to different requirement of the streetlight intensity in different environments, a measurement and control circuit for white LED streetlight powered by the solar cell and accumulator is designed in this paper, There are three control modes of light controlling, delay off and low power output after delay in this circuit. The brightness detection is accomplished by photocell as a photosensitive test component in this system. The single-chip microcomputer is used to complete timing, adjustable PWM power output, and the streetlight delay off or low power output light after delay. VMOS transistor is used to drive LED streetlight. The test indicated that lights off during the da...
