Abstract

The invention relates to LED illumination, in particular to a corridor LED lamp control circuit. The technical problem of the invention is to provide a corridor LED lamp control circuit which is high in sensitivity and can save electric energy. The technical scheme is that the corridor LED lamp control circuit comprises an alternating current input end, a resistance-capacitance voltage reduction circuit, an LED work indicating lamp circuit, a rectifying circuit, a timing circuit, a voltage stabilizing circuit, an electric signal amplifying circuit, a triode control circuit, a microphone, a reference voltage setting potentiometer, a timing setting circuit and an LED illuminating lamp. The output end of the resistance-capacitance voltage reduction circuit is connected with the input end of the rectification circuit, and the output end of the rectification circuit is connected with the input end of the voltage stabilizing circuit. According to the corridor LED lamp control circuit, the voltage of the timing circuit can be stabilized through the voltage maintaining circuit, the situation that the LED lighting lamp stops working due to the fact that other people pass through the corridor when the LED lighting lamp works can be avoided, and the sensitivity of the corridor LED lamp control circuit is improved.

Description

technical field [0001] The invention relates to LED lighting, in particular to a corridor LED lamp control circuit. Background technique [0002] Because the light in the corridor is not good, people generally install LED lights in the corridor, so as to provide light for people when it is late, and prevent people from falling when going up and down the stairs. [0003] The existing corridor LED lights are usually controlled by light control or sound control. The installation circuit is relatively simple, but the sensitivity is not high, and sometimes people need to make a loud noise to be sensed, which is inconvenient for people to use. When some corridor LED lights are extinguished, they cannot be completely extinguished, and there will be a little weak light, which will cause a waste of electric energy. In view of the above problems, a corridor LED lamp control circuit with high sensitivity and energy saving is designed. Contents of the invention [0004] In order to o...
