According to the person in charge of the facility management office, the state and the Chongqing municipal government are implementing green lighting, and promoting the use of LED energy-saving lamps may be a trend in urban lighting in the future. This time, 65 sets of LED street lights were replaced in Changzhou Avenue, which is our test of LED energy-saving effect and main lighting indicators. If the demonstration effect is good, the next step may be further promoted.
In addition to the advantages of energy saving, environmental protection and long life, LED street lights can also improve the illumination of specific areas or targets. Chongqing LED lighting renovation project will also apply intelligent management system, which can not only automatically turn on and off the lights according to natural lighting conditions, but also automatically adjust the intensity of light to further enhance the LED lighting effect. 
Since the city was selected into the national “Ten Cities and Ten Thousands†semiconductor lighting application project implementation city, Chongqing has made great progress in LED lighting development, and launched the Chongqing semiconductor lighting industry technology demonstration support project, and established LED technology support demonstration base in Beibei District.
