In this paper, a kind of intelligent LED lighting system was designed, and intelligent pro-cessing and control technology were obtained based on STC89C52 MCU minimum system,which combining with the LED lighting technology, infrared sensing technology, photo-electric detection technology. The system can intelligently test the design of LED lightingsystem, realize the intensity of light control, infrared detection and the measurement oflight intensity, reflecting the intelligence and humanity of LED lights, and further to achieveenergy-saving green lighting.
