Resistor R2 is a photosensitive resistor.

The working principle of the utility model is: the wind power generator M is arranged in the middle of the orchard, the wind power generator M completes the wind power conversion and turns it into direct current through a bridge rectifier circuit composed of diodes D1~diode D6, and the capacitor C1 is a filter capacitor. Part of the direct current is stored in the storage battery E after passing through the anti-reverse diode D1, and the other part is used to supply power to the circuit. The triode V2 in the circuit acts as a hysteresis to the comparator IC1, so that the comparison circuit has two threshold voltages: V1 and V2 , and V1>V2, a hysteresis region. When the voltage of the battery E rises from low to V1, the comparator IC1 outputs a high level; when the battery voltage drops to V2, the comparator IC1 outputs a low level. At this time, although the battery terminal voltage will rapidly rise above V2, but because it cannot reach V1, the comparator IC1 still outputs a low level until the battery E is charged and the voltage rises above V1 before outputting a high level again. . In this way, the oscillation of the circuit is avoided, and the LED light group H and the battery E are not repeatedly jumped because the voltage is at a critical point. The positive terminal 1 of the comparator IC1 reflects the sampling voltage U1 of the battery, and the comparator IC1 The negative terminal 3 of the negative terminal reflects the reference voltage U2 of the battery. When U3>U2, the comparator IC1 outputs a high level. Since the photosensitive resistor R2 is set in the circuit, its resistance value is very low during the day, so the circuit does not operate during the day. To work, only when the light is insufficient at night, the resistance value of resistor R2 increases, the triode V1 can be turned on, the triode V3 is cut off, and the LED lamp group H does not work; when U3<U2, the comparator IC1 outputs a low level, and the triode V1 is cut off , the triode V3 is turned on, the LED lamp group H does not work, and the potentiometer RP1 can also adjust the brightness of the LED lamp.
