With the continuous stretch of urban development, the existing street light control method has been far from city lights can not meet the needs of development and control, so the use of advanced science and technology for effective control and management is the inevitable.?Development of technology?in modern?lights,?street lamps?on the?intelligent control?is very important. The design is based on photosensitive resistor control theory, which is based on LED lighting design intelligent control system, intelligent control of LED lights.?The system consists of photosensitive detection module, the noise detection module, the clock circuit, the relay switch, an external current source module, LCD display module, and ZigBee wireless module, application STC89C52 MCU control, LED lights through the analog control for the final?reference for the practical applications.?And analyzed the problems in t
