In the field of green lighting, high-power LED drive design is becoming more and more important in order to achieve both energy saving and high light efficiency. According to the characteristics of high-power LED, a drive and control system for white light LED with different parameters is designed. The system is based on the single-chip microcomputer C8051F040, combined with peripheral circuits, and uses digital control technology instead of analog circuit control to perform high-precision control of the constant current drive current of high-power LED, as well as automatic adjustment and control of LED brightness, realizing a variety of high-power LED intelligent lighting.
