Traditional lighting changed to LED lamp, Zhejiang Tongxiang street lamp transformation, saving electricity 30%

A few days ago, Tongxiang Zhonghua Road got the electricity bill: in June this year, the street lamp tariff was 10882 yuan, which was 1/3 lower than that of the same period last year. Thanks to street lighting.

In recent years, Tongxiang has gradually changed the traditional road lights to LED lights. Last year, Tongxiang completed the energy saving transformation of 63 roads and 4427 street lamps, saving 4 million 125 thousand and 400 kilowatt hours of electricity per year and saving electricity bills by nearly 4 million yuan.

It is reported that the total number of street lamps in Tongxiang is up to 42 thousand, of which street lamps mainly use high pressure sodium lamps and metal halide lamps. Now, after some street lamps have been transformed, the intensity of light is constant, and the energy saving effect is very obvious. China road originally installed 250 watts high voltage sodium lamp 118, 150 watts high pressure sodium lamp 129, the total power is 48.8 kilowatts. After transformation, 247 watts of LED street lamps are installed, with a total power of 33.3 kilowatts and a power saving rate of 32.5%. 135. With a street lamp working for 11.5 hours per day, the annual electricity consumption is 65 thousand and 100 kwh, which is equivalent to the monthly electricity consumption of 651 households according to the average monthly household electricity consumption of 100 kwh.

In addition, the workload of maintenance has also decreased significantly. Gao Xiaofei, deputy general manager of Tongxiang power supply company, said that ordinary lights consume a lot of electricity and have a short life span, and they need to be replaced in two years. The cost of maintaining and replacing LED street lamps in 6 years is very small.
