摘　　要：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。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.
