Recently, the nation's largest city-level intelligent LED street lamp renovation project based on DC power supply – Zhaoqing High-tech Zone LED street lamp energy-saving renovation project completed and accepted. A total of 5,722 LED street lights were installed in the project. After third-party energy conservation assessment, the project's power saving rate reached 66%, saving electricity of 4.95 million kWh per year, equivalent to saving 1,700 tons of standard coal, reducing carbon dioxide emissions by 4,690 tons, and reducing lighting load by 1354. Kilowatts, saving electricity costs of 4.06 million yuan per year. After the renovation, the road illumination increased by 26%.
The DC centralized power supply and intelligent control system built by the project integrates various technologies such as cloud platform, IoT perception, control and data processing. Through the intelligent control system, various functions such as dimming control can be realized, and the mobile terminal can also be used. The remote monitoring of the lamps and lanterns truly realizes the intelligent and refined management of the lighting system, greatly prolongs the service life of the lamps and systems, improves the stability of the system, achieves a secondary energy saving of more than 20%, and greatly reduces the maintenance cost of the street lamp system.
