Summary of the invention
The control circuit that the purpose of this invention is to provide a kind of LED electricity-saving lamp can not automatically adjust with the brightness that solves LED light fixture in the prior art according to actual needs, and then causes the wasting of resources and reduce the LED light fixture problem in useful life.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of control circuit of LED electricity-saving lamp; It is characterized in that: include step-down rectifying circuit, electronic switching circuit, single-chip microcomputer and light control sensor; Said step-down rectifying circuit is made up of four groups of safety electric capacity and rectifier bridge; After converting the constant voltage direct current to, four groups of safety capacitance decompressions and the rectifier bridge rectification of alternating current in step-down rectifying circuit send into electronic switching circuit; The output of said electronic switching circuit is connected with the input of led array; Said light control sensor is gathered the surrounding environment optical information and is converted the signal of telecommunication to and sends single-chip microcomputer to, and said single-chip microcomputer is controlled electronic switching circuit after judging according to the signal of telecommunication that receives, and then the brightness of control led array changes.
The control circuit of described a kind of LED electricity-saving lamp is characterized in that: said single-chip microcomputer is selected PIC16F688 or PIC16F689 or PIC16F690 or PIC16F88 for use.
Beneficial effect of the present invention is:
The present invention is input to single-chip microcomputer through the light control sensor image data, thereby the control electronic switch carries out the adjusting of different brightness gears, reaches the purpose that automatic control LED lamp brightness changes; Practice thrift electric energy effectively, made the LED lamp needn't be in the high brightness running status for a long time simultaneously, guaranteed LED lamp useful life; The present invention is simple in structure, and the components and parts of use are common component, and are convenient for production; Cost is low; And circuit originally has stability preferably, is difficult for breaking down, and has effectively ensured the safe and stable operation of LED lamp.
