Wuxi high pressure mercury lamp for 4 years to recover the cost of LED street lamp

Put a high pressure mercury lamp of 80 watts for a new LED light source lamp of 30 watts, the electricity savings of about 4 years can recover the cost. From February 9th Wuxi lighting management department learned that since the city launched a green lighting energy saving and emission reduction, last year by LED lighting, solar energy, energy management contract, the "three remote" system of centralized control and other means, a total saving 31 million 258 thousand kwh, saving electricity 22 million 28 thousand yuan, the actual occurrence of electricity 122 million yuan, saving rate of 14%.

In November last year, combined with the transformation of the old village, Wuxi lighting management office for the replacement of 250 sets of new LED light source street lamps, with more than 20 years of flat iron lamp laid off. After installing the lights, residents generally reflect, 30 watt LED lamp than the original 80 watts of high-pressure mercury lamp, a lot of bright". Flat iron lamp is installed on the poles, only one enamel cover, the following one of the most simple lamp bulb. As the light bulb exposed in the air, 80 watts of power, in fact, most of the diffuse in the air, the real power of the ground to see the effective power of only twenty or thirty watts, large energy consumption, poor lighting effect. Therefore, high-pressure mercury lamp, such as inefficient lighting products have been phased out. As an efficient light source, LED street lamp efficiency can reach more than 90%, although only 30 watts, but a lot of lighting quality improvement, but also save electricity.

Last year, the Wuxi Lighting Management Office of the new century garden, Cao Zhang village 24 new village, the district replaced the 1703 LED lights, lighting safety factor to improve the operation. According to the cost of 0.882 yuan per square meter to calculate a set of LED lights down a year can save about $200 electricity bill. If you do not consider the overhead line and other aspects of the transformation of the cost of light for a lamp, then, LED new light source through the energy saving electricity costs about 4 years to recover all costs. Xu Jin, assistant director of Wuxi lighting management, said, in the next few years, the use of LED will be more and more widely, more stable, the price will be lower and lower. "In the past three years, Wuxi lighting management office on solar power, LED lighting, energy management contract, the night lights, landscape lights time control, two stage ballast," three remote "system of centralized control and many other means to carry out energy-saving work, effective, power saving rate of city lighting each year reached more than 10%. A total of three years to save electricity 50 million yuan. As the first contract energy management in city lighting management work of the city, the city now has 44 distribution facilities to implement the energy saving mode, covering more than 10 thousand lights, annual electricity savings of about 1000000 yuan, the saving rate at about 23%.
