Urban public street lighting to beautify the city, improve the investment environment, promote social and economic development can not be ignored and security plays an important role in peoples lives and the safety of road traffic safety and other aspects. Especially since the reform and opening up, with the gradual development of Chinas economic construction, and gradually increase the pace of development of urban road construction, community and the people of the lighting rate and the image of the city have become increasingly demanding. Therefore, as an indispensable urban construction and management of urban road lighting also put forward higher requirements. The graduation project designed primarily to energy-efficient solar-powered street lighting system. Solar street lighting system includes power module, sensor module, SCM(single-chip microcomputer)control module and LED lamp module.System uses STC89C52 SCM as the core of control circuit devices, a 1 w LED street light and ultrasonic ranging module, which use the technology of PWM (pulse modulation) control street lamp brightness, and the 1602 LCD displays the detection distance. The solar street lighting system utilizes the principle of photovoltaic effect, during the day, the system goes into sleep mode during the day and received by the photovoltaic panels and solar radiation into electrical energy output, after the charge-discharge device will power stored in the battery.When
