LED Smart Street Lights

Jun 09, 2020

he Daxing Airport Expressway has been in operation for nearly a year since it was officially opened on July 1, 2019, with a total traffic volume of 17.44 million. Since its opening, this "smart street light" on this high-speed road has saved a total of about 400,000 kWh of electricity, with a comprehensive energy saving rate of 30%.

If citizens drive at high speed at Daxing Airport at night, they will find that the street lights along the way are shining like stars, and these seemingly insignificant street lights have "great wisdom". The LED lighting technology is used throughout the high-speed line of Daxing Airport. More than 5,000 sets of lamps have been installed. 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 is more comfortable.

Wisdom is first reflected in the fact that each street light can be remotely controlled and individually dimmed. Through the application of LoRa Internet of Things technology and access to wireless communication networks, a unique "smart street light" control scheme has been created. The system can individually steplessly dim each street light. Under the premise of ensuring lighting needs, it can be based on different road sections. 3. Set the operation plan of street lamps at different periods and with different traffic flows, flexibly respond to changes in lighting demand caused by sudden weather, seasonal changes, etc. 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, the comprehensive use of the GIS map technology of the monitoring system can real-time online understanding of the running status of all street lamps, realize automatic inspection of street lamps and automatic alarming of failures, guide operation and maintenance personnel to carry out active operation and maintenance and directional maintenance. The hotline operation and maintenance method greatly improves the operation and maintenance efficiency and saves maintenance costs.
