To resolve the eternal fire of the factory, the paper designed a energy-saving lamp circuit controlled by sound and light for corridor lighting. Its function: when upper and lower floor at night, the light will automatically light up, and after 2-3 minutes will automatically turns off; if in the day, the light will not light up. Whole circuits include power supply circuit, amplifier circuit, processing circuit (voice control circuits, optical control circuit) and delay circuit and other elements.%为解决工厂长明灯现象,设计了一种声光双控节能电路供楼道照明灯用,其功能:夜间有人上下楼时,照明灯自动点亮,灯亮后延时2～3分钟,会自动熄灭；白天照明灯受人走动的控制,灯不会点亮.整个电路由电源电路,放大电路,处理电路(声控电路、光控电路)及延时电路等部分组成.
