On September 13, the 2018 annual public lighting system LED lamp energy-saving promotion project in Tongzhou District, Nantong, Jiangsu Province was basically completed. At this point, this year, Tongzhou District replaced 8348 LED LED lamps.
LED is a new type of green illumination source with low energy consumption, good light directivity, long life and fast response, which meets the national green lighting and energy saving requirements.
Since 2014, the public lighting system in Tongzhou District has promoted the application of LED lamp energy-saving renovation projects. In 2015, after investigation and demonstration, Tongzhou District selected four roads including Qingdao North Road, Henghe South Road, Beiyihuan and Wuyi Road to carry out pilot application of LED lights. In 2016, based on the preliminary results of the application of LEDs, the district government decided to use LED lights for the public lighting system in Tongzhou District in three years to transform the traditional light sources such as metal halide lamps and high-pressure sodium lamps into LED street lamps.
In the past three years, the Tongzhou District Housing and Construction Bureau has carefully organized and promoted it. At present, the total number of LED lamps used in the transformation of the whole district is 17,334. After the renovation and replacement of the construction, the illuminance and uniformity of the tested LED lamps reached and exceeded the national standards. Compared with the same period in 2015, the electricity cost was saved by 261,000 yuan. After actual calculation, the electricity cost was reduced by nearly 4 million yuan in one year. The application of LED lights in public lighting systems has achieved remarkable results in energy saving and consumption reduction.
