Solar energy discharge loop of duplicate supply string lights

Abstract

The invention discloses a solar energy discharge loop of duplicate supply string lights. The solar energy discharge loop of duplicate supply string lights is formed by a charging battery, load stringlights, a controller, a resistor R1, a resistor R2, a resistor R3, a resistor R4, a triode T1, a triode T2, a field effect transistor T3, a diode D1, and a capacitor C1. Therefore, through combinationof the components, and by means of control of the discharging process by the controller, the solar energy discharge loop of duplicate supply string lights can effectively reduce the loss of electricenergy during the discharging process, can prolong the time of discharging, and can increase the lighting time of the load string lights.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a solar discharge circuit for double power supply lamp strings. Background technique [0002] At present, most of the solar light strings on the market use polysilicon panels to absorb light energy and convert it into electrical energy to charge nickel-hydrogen batteries or lithium batteries. By absorbing light energy, they are charged during the day and discharged at night. The reason is that too much light energy is often not absorbed, which leads to a short lighting time of the light string, about 10 hours. If in order to increase the discharge time, it is necessary to increase the battery capacity and charge the polysilicon board, and this will make the cost relatively Therefore, how to improve the reliability in the process of power transmission and reduce the cost are technical problems that need to be solved at present. Contents of the invention [0003] In order to so...

If in order to increase the discharge time, it is necessary to increase the battery capacity and charge the polysilicon board, and this will make the cost relatively Relatively high, therefore, how to improve the reliability in the process of power transmission and reduce the cost is a technical problem that needs to be solved at present
