Abstract
The utility model discloses a simple light-operated automatic switch comprising a transformer, a rectification circuit, a voltage stabilizer, a capacitor, a potentiometer, a photoresistor, a triode, and a solid-state relay. The second end of the potentiometer is simultaneously connected with the second end of the photoresistor, the base electrode of the triode, and the collector electrode of the base electrode. The emitter electrode of the triode is connected with the second end of the solid-state relay. The control end of the solid-state relay is connected with the power end of a load. In the simple light-operated automatic switch, a photoelectric switch is formed by the photoresistor, the triode, and a trimming resistor. Presenting a low resistance caused by illumination in daytime, the photoresistor is in a cut-off state and thus the solid-state relay does not operate. Presenting a high resistance caused by no illumination of high light at night, the photoresistor acquires appropriate bias current to be conducted and thus the solid-state relay operates. The simple light-operated automatic switch has characteristics of few switching elements, a simple circuit, and reliable operation, and is beneficial to popularization.
