Successful Application of Intelligent LED Street Light in Daxing Airport
The Daxing Airport Expressway has been in operation for nearly a year since its official opening on July 1, 2019, with a total of 17.44 million vehicles. Since its opening, the “smart street lights” on this highway have saved about 400,000 kWh of electricity, and the overall energy saving rate has reached 30%.
If citizens drive along the Daxing Airport Expressway at night, they will find that the street lights along the way are like galaxies, but these seemingly inconspicuous small street lights have "great wisdom." The Daxing Airport Expressway adopts LED lighting technology and has installed more than 5,000 sets of lamps. Compared with traditional high-pressure sodium lamps, this street lamp has lower energy consumption and higher energy efficiency. The color temperature is close to natural light, the light is uniform, and the look and feel is more comfortable.
"Intelligent" is firstly reflected in that each street light can be remotely controlled and dimmable. Through the application of LoRa, which is accessful to the wireless communication network, a unique "smart street light" control scheme has been created. This system can individually and steplessly dim each street light. Under the premise of ensuring the lighting requirements, it can be based on different road sections. , Different time periods and different traffic flows set street lamp operation schemes to flexibly respond to changes in lighting demand caused by sudden weather and seasonal changes. Through refined lighting strategies, the energy-saving effect of street lamps is greatly enhanced and the service life of street lamps is extended.
In addition, comprehensive use of the GIS map technology of the monitoring system can real-time understand the operating status of all street lights online, realize automatic street lamp inspection and automatic fault alarm, and guide operation and maintenance personnel to conduct active operation and maintenance and directional maintenance, which has changed the previous manual inspection, The operation and maintenance mode of hotline repairs greatly improves operation and maintenance efficiency and saves maintenance costs.
