全自动节能灯的设计与实现

全自动节能灯是通过智能系统自动调节灯光亮度以及明灭,解决灯的光强度过高以及无人时灯未关闭造成的能源浪费问题,通过检测外界光线采用PWM脉冲调制对灯光进行相应的亮度调节以及无人和外界光线充足的情况下自动关灯来达到节能减排的目的。本设计以单片机为中央控制单元,主要由热释电红外传感器电路,光强信号处理电路组成,软件选用C语言编程。

The automatic energy-saving lamp automatically adjusts the brightness of the light and clears it through the intelligent system,solves the problem of energy waste caused by the high light intensity of the lamp and the unclosed lamp.The external light is detected by pwm pulse modulation.The brightness is adjusted and the lights are automatically turned off when there is no one and the outside light is suff icient to achieve energy saving and emission reduction.This design takes the single-chip microcomputer as the central control unit,which is mainly composed of pyroelectric infrared sensor circuit and light intensity signal processing circuit.The software uses clanguage programming.
