Design of White Light LED Lighting Control System

Traditional street lamps often use high pressure sodium lamp 360 degree light emitting. Because of the great loss, they cause great waste of energy. In the current environment of promoting clean energy development, higher demand for energy saving has been put forward. LED lamps, which can meet the demand of lighting and achieve energy saving effect at the same time,and can convert electric energy into light energy, and have the advantages of high conversion efficiency, green environment protection, long service life and low working voltage. Therefore, LED lights have been used more and more widely in all fields, especially in the lighting of families and public places.,,,, The design is based on AT89S52 microcontroller as the core of street lighting control system. The white LED lamps to replace the traditional light source, dimming with PWM white LED lighting simulation controller can effectively achieve the series of white LED lamp on and off, and can adjust the brightness level, and has a key lock function.
