Chancheng LED street lights three phase transformation completed 8 million annual electricity saving

The Pearl River Times news yesterday, reporters learned from the Chancheng municipal public facilities management technology service center, Chancheng large-scale urban road LED street lighting third phase transformation project has been completed recently, 12 thousand LED street lamps to replace the original high-pressure sodium lamp, to achieve the upgrading of the main road lights, with significant energy saving. Environmental protection benefits.

It is understood that most of the street lamps in Chancheng were built in the 80s and 90s of last century. The lamps and lanterns are mainly high pressure sodium lamps. The lamp has high energy consumption, short life, high maintenance cost and poor chromaticity, resulting in low landscape definition. In order to maintain the necessary lighting, the public utilities in Chancheng district have to increase the power of some main street lamps, resulting in excessive power density of many road lighting and wasting a lot of power. However, some branches are not illuminant enough and the roads are dim. In addition, HP lamps contain mercury and sodium, and subsequent waste disposal has great environmental pollution.

In order to promote energy saving and emission reduction and industrial upgrading, Chancheng district has implemented the LED street lamp transformation of urban roads since November 2008, and completed the two phase project in November 2009, with 9372 LED lamps installed on some roads. The third phase LED street lamp transformation in Chancheng district began construction at the end of 2013. The transformation involved more than 140 roads, including the ancestral temple, Shiwan and Zhang Chasan streets, and installed 12 thousand LED streetlights.

What is the effect after transformation? District municipal public facilities management technology service center responsible person cited an example: take the Fenjiang Road (Tongji intersection to Jihua intersection) as an example, the entire section of the replacement of LED street lights 165. Before the transformation, the street lamp at night was 571.20KW per hour, and the hourly power was 253.93KW after the transformation. The electricity saving rate reached 55.54%. The illumination still accorded with the national standard, and changed the low color index of the high pressure sodium lamp, and the color of the scenery was not clear enough. The warm white light made the surrounding scene look clearer. It is estimated that after the completion of the three phase of the project, the same number of high-pressure sodium lamps, using LED street lamps to save electricity by 8 million degrees per year, is equivalent to the annual emission reduction of 6700 tons of carbon dioxide in Chancheng district.

Chancheng district municipal public facilities management technology service center responsible person said that after the three phase of the LED street lighting transformation, it will continue to maintain the LED street lamp, so that the night road will be brighter and provide convenience for people's life.
