LED solar lighting system allowing light color to be controllable

Abstract

The invention provides an LED solar lighting system allowing light color to be controllable. The LED solar lighting system comprises a photovoltaic conversion circuit, a control key, an oscillating circuit, a single chip microcomputer, a single chip microcomputer driving circuit and an LED lamp assembly; the photovoltaic conversion circuit converts light energy into electric energy and stores the electric energy to supply the electricity to the whole system, and the oscillating circuit provides an oscillating timing sequence source for the single chip microcomputer; the single chip microcomputer driving circuit provides a voltage required by work for the single chip microcomputer; the control key is connected with a level signal input pin of the single chip microcomputer and controls level changes of the level signal input pin of the single chip microcomputer, it is set that an output end voltage of the single chip microcomputer is changed, and three output ports of the single chip microcomputer supply the electricity to the LED lamp assembly. The LED solar lighting system allowing the light color to be controllable is simple in structure, and color changes are controlled through an internal program of the single chip microcomputer more accurately and stably; a stable high level is provided for driving the single chip microcomputer to work by means of the amplified action of an NPN type transistor, and therefore operation stability of the whole lamp tube system is greatly guaranteed.
