Abstract

The invention discloses a light-operated street lamp controller circuit. The light-operated street lamp controller circuit comprises an alternating current power supply, an illumination lamp, a transformer, a bridge rectifier, a first resistor, a second resistor, a first photoresistor, a second photoresistor, a double-d-trigger, a first potentiometer, a second potentiometer, a first capacitor, a second capacitor, a diode, a triode, a voltage stabilizing diode and a relay; in daytime, the first photoresistor and the second photoresistor are in a low-resistance state due to light irradiation, the direct setting end of the double-d-trigger is in low level, the inverse code output end outputs low level, the diode is in a cut-off state, the relay is in a released state, and the illumination lamp is off; at night, the resistance value of the first photoresistor and the second photoresistor is increased due to absence of light irradiation or weakened light irradiation to enable the direct setting end of the double-d-trigger to be in low level, the inverse code output end outputs high level, the diode is conducted, the relay is electrified and pulled in, and the illumination lamp is on. The light-operated street lamp controller circuit is stable in performance and high in sensitivity.

Description

technical field [0001] The invention relates to a light-controlled street lamp, in particular to a light-controlled street lamp controller circuit. Background technique [0002] The light-controlled street light controller can automatically realize the automatic lighting of street lights in the dark during the day and at night, which is convenient and practical. It not only saves electric energy, but also prolongs the service life of the bulb. It can be widely used in stairs, corridors, bathrooms and living quarters. This controller is economical and practical for lighting control in public places. However, the performance of the traditional light-controlled street lamp controller is unstable and the sensitivity is not high. Contents of the invention [0003] The object of the present invention is to provide a light-controlled street lamp controller circuit in order to solve the above problems. [0004] The present invention achieves the above object through the followin...
