In recent years, with the development of Lishui City, the number of municipal street lamps has increased geometrically. These street lights not only illuminate the night life of citizens, but also illuminate the way home, but also inevitably consume a lot of electric energy. Now, the reasonable configuration and effective operation of urban lighting system has become an important symbol to measure the city appearance. Lishui power supply company actively launched the green pilot project of LED energy-saving street lights, promoted the energy-saving work of street lights under EMC contract energy management, and explored the way of urban lighting.
