At present domestic lamp lighting source usually adopts the high-pressure sodium lamp, high-pressure mercury lamps and halogen lamps. Often, the night lights, The lights or later, the earlier, not only caused great power waste, affect Peoples Daily life, also can damage the image of the city, the influence of social security and traffic safety, and thus affect the citys investment environment. Anyhow, with the expansion of city street， the existing methods of management cant satisfy the development and management of urban street, must rely on modern high-tech management. Electric lamp switch invention and use appears very important. Based on the basic principle of photoconductive resistance, based on optical switch street lamps, realize the automatic control system of intelligent control. This system mainly by photoelectric conversion, op-amp lag comparison, driver stage, through the electric circuit design and simulation, the practical application for reference， The research and analysis of the problems appeared in the process, gradually find optimal design method of optical switch.
