With the LED lighting energy-saving renovation project of the last three tunnels of Huangshagang, Huangtan and Xincheng of Longqing Expressway ending smoothly on October 9, the entire tunnel of Longqing Expressway have completed the energy-saving renovation of LED lights, which is the first full line of the city. The tunnel realizes the full coverage of the LED lights.
It is understood that this lighting energy-saving renovation plan will replace the original 6000-inch tunnel high-pressure sodium lamp one-to-one with LED energy-saving lamps to meet the luminous efficacy, luminous flux, light attenuation, life, light color and color rendering of the illumination source in the tunnel. Sexual requirements, fully realize the intelligent lighting brightness adjustment, while ensuring good visibility in the smoke formed by automobile emissions, and more convenient for the public to travel.
Since 2017, Longqing Expressway has implemented the energy-saving renovation plan for tunnel lighting equipment and has completed the energy-saving renovation project of 10 tunnel LED lights across the entire line. The total length of the two-way tunnel is more than 10 kilometers. After the renovation, it is estimated that the annual electricity consumption will be more than 600,000 kWh, and the energy-saving rate will be as high as 50% or more.
In the next step, the equipment technicians of the Longqing Expressway Management Office will further optimize the tunnel lighting scheme, conduct energy consumption assessment tests and compare the brightness before and after the transformation, and at that time, energy consumption savings will be maximized.
