Abstract: Urban road lighting is an important part of urban infrastructure. It shoull not only meet theneeds of people's travel at night , but also take electric energy conservation into consideration . The intel-ligent lighting control system can control the switching time of street lamps and adjust the brightness ofamps according to the time , weather conditions and the demand of popular traffic volume , and can man-age the operation and maintenance of street lamps, so as to realize the refinement and energy-saving con-trol of street lamps. This paper discusses the structure and control function of an intelligent control systemfor road lighting, and the realization method of dimming and energy conservation. Taking the city streetlamps of a county as an application case , its energy-saving efleet is studied. It is of great significance topromote the transformation of street lamps in small and medium-sized cities.

Key words: roxl lighting, intelligent control, energy conservation
