Abstract

The invention provides a control circuit for double-purpose energy-saving flashlight of solar energy and AC charging, which is used to solve the problem that prior flashlight is supplied by one energy resource or the battery should be exchanged often, comprising transformation module of switch power supply, module of charging control and indication, module of LED driven circuit, module of LED lighting circuit, solar battery board and the switch of flashlight. AC with 200v is connected with the input of exchanging module of switch power supply. The first input of module of charging control and indication is connected with the output of exchanging module of switch power supply. The input of solar battery board is connected with the second input of module of charging control and indication. The output of module of charging control and indication is connected with one end of flashlight switch and the other end of flashlight switch is connected with the input of module of LED driven circuit and the output of module of LED driven circuit is connected with the input of module of LED lighting circuit. It can be charged by solar battery or AC.

Description

technical field [0001] The invention relates to a flashlight control circuit, in particular to a solar / AC charging dual-purpose energy-saving flashlight control circuit. Background technique [0002] In the control circuit of flashlight in the past, there are following deficiencies: 1) the control circuit in the flashlight that has only has the solar cell panel charging part. 2) The control circuit in some flashlights only has a simple capacitor step-down AC mains charging function. 3) The control circuit in the flashlight also needs to replace the battery frequently during use. Therefore, these flashlights have the disadvantages of relying solely on a kind of energy supply or requiring frequent replacement of batteries, and cannot be well adapted to the use environment. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the above-mentioned flashlight control circuit, and provide a dual-purpose energy-saving flash...
