白天时,光敏电路发给单片机一个高电平,单片机进入低功耗模式(此时热释电电路不工作);晚上时,光敏电路发给单片机一个低电平,单片机退出低功耗模式,进入待机模式,没人经过LED路灯的时候,热释电电路发给单片机一个低电平,此时单片机输出一个较低占空比的PWM信号给LED驱动电路,LED路灯发出相对微弱的光(由于PWM占空比可通过程序改变,所以微弱光的强度也可调);当有人经过路灯时,热释电电路发给单片机一个高电平,此时单片机输出一个较高占空比的PWM给LED驱动电路,LED路灯发出较强的光(光强也可通过程序调动);当人与LED路灯的距离慢慢加大时,热释电电路将发给单片机一个低电平,LED路灯发出较微弱的光。 During the day, the photosensitive circuit sends a high level to the microcontroller, and the microcontroller enters a low power consumption mode (the pyroelectric circuit does not work at this time); at night, the photosensitive circuit sends a low level to the microcontroller, and the microcontroller exits the low power consumption mode. Enter standby mode, when no one passes by the LED street lamp, the pyroelectric circuit sends a low level to the single-chip microcomputer, at this time the single-chip microcomputer outputs a PWM signal with a lower duty cycle to the LED drive circuit, and the LED street lamp emits relatively weak light ( Since the PWM duty cycle can be changed by the program, the intensity of the weak light can also be adjusted); when someone passes the street lamp, the pyroelectric circuit sends a high level to the microcontroller, and the microcontroller outputs a higher duty cycle PWM For the LED drive circuit, the LED street lamp emits a strong light (the light intensity can also be adjusted through the program); when the distance between the person and the LED street lamp gradually increases, the pyroelectric circuit will send a low level to the microcontroller, and the LED street lamp emits a weaker light.

And it can be remotely controlled and detected, and the brightness and color temperature can be adjusted to truly achieve the intelligence and personalization of solar street lights. It is especially suitable for street lighting on campus, and lighting in places with many rainy days.
