Light-operated automatic switch of solar decorative lamp

Abstract

The invention relates to a light-operated automatic switch of a solar decorative lamp. The primary pole of a transformer is connected with an accumulator. The accumulator is connected with a solar power generating unit. The secondary pole of the transformer is connected with the input end of a rectifying circuit. The cathode of a rectifier circuit is connected with the first end of a capacitor, the control end of a voltage stabilizer, the first end of a photoresistor and the first end of a solid-state relay. The anode of the rectifier circuit is connected with the input end of the voltage stabilizer and the first end of the capacitor. The output end of the voltage stabilizer is connected with the sliding end and the first end of a potentiometer. The second end of the potentiometer is connected with the second end of the photoresistance, the base electrode of a triode and a collector electrode of the triode. The emitter electrode of the triode is connected with the second end of the solid-state relay. The light-operated automatic switch realizes automatic switching through light control and has advantages of saving labor in manual switching, managing in a unified manner, and realizing electric energy saving.

Description

technical field [0001] The invention relates to a switch control device, in particular to an automatic switch for solar decorative lighting control. Background technique [0002] For special holiday occasions such as National Day and Spring Festival, decorative lights will be hung on trees in leisure squares in towns to add a festive atmosphere. Usually, they need to be turned on at night and turned off in the morning. Existing decorative lamps are usually switched on and off manually, which has the outstanding problem of consuming manpower. Moreover, it is difficult to unify the switching time. If it is turned on too early, the power consumption will increase, and if it is turned on too late, the decorative effect will be affected. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the current technology, to provide a solar decorative lighting control automatic switch that realizes automatic switching through light c...
