It can directly replace lighting switch without change original lighting. Daytime or strong light situations have bigger sound even not bright, also control bulb or dark night when noise (such as voice and sound, etc.), then the automatic light back 10 seconds (time) can be extinguished, applicable to the stairs, only short-time lighting corridor. The circuit by voice circuits, delay circuit, electric circuit, electronic switch, the power circuit. Power supply voltage power supply, photosensitive control circuit of external light, output and degree of relative degree of voltage signal intensity. So as to realize the bright light at night during the meeting, the sound, through the sonic circuit make light bulb automatic, televox circuit will sound signal into electrical signals, thus to realize the automatic control circuit, delay extended a DuanGuangZhao voice disappears.
