In recent years, with the development of Lishui City, the number of municipal street lamps has increased geometrically. The streetlights illuminate the nightlife of the citizens, illuminate the way home, and inevitably consume a lot of electricity. Under the leadership of the local government, Lishui Power Supply Company started the green pilot project of LED energy-saving street lamps, effectively promoted the energy saving of EMC contracted energy management street lighting, and explored the road of urban lighting. In June 2009, Liandu District Power Supply Company signed a contract with Ningbo Instant Lighting Co., Ltd. to officially launch the green energy-saving street lamp pilot project on both sides of Zijin Road. The pilot section is 1km long and the street lamp is replaced 50ç›. After testing, LED optical energy-saving street lamps use optical light distribution, new reflectors and other technologies compared with the traditional high-pressure sodium lamps replaced, brightness increased by 4 times, light utilization increased by more than 60, power consumption is lower than traditional high-pressure sodium lamps 60. At present, the first batch of LED energy-saving street lamp pilots have been successfully operated for 1,480 days. In April this year, Jinyun County Power Supply Company officially launched the contract energy management operation mode to invest, transform and maintain part of the street lights in the county area. The street lamp energy-saving renovation project involves 1365 baht of street lamps. After the completion of the renovation, the service life of the street lamps is not less than 30,000 hours, the power factor is higher than 0.9, and the energy-saving effect is over 50. After the renovation of the street lamps, it is estimated that the annual labor maintenance cost can be saved by about 336,000 yuan, and the loss of spare parts materials is about 1.8 million yuan. According to the survey, there are currently 71 bright lighting spots in 71 urban roads in Lishui City. A total of 14065 è·¯ street lamps are installed. The power of only the light source reaches 1925 kW, and the annual power consumption is about 9.422 million kWh, 0.9 yuan per kWh. Calculated, the annual electricity expenditure is 8.48 million yuan. What is the concept of 9.422 million kWh a year? Calculated according to an average household's monthly electricity consumption of 300 kWh, this electricity is enough for a household to use 2617 years. It can be seen that the energy saving of street lamps is not a trivial matter. The person in charge of the business department of Lishui Power Supply Company said.
