Two tunnels of Wuhan-Shenzhen Expressway have renewed their LEDs to “clear the way”

In order to improve the traffic conditions in the tunnel and the lighting conditions in the tunnel, reduce driver fatigue, improve the tunnel capacity, and ensure traffic safety. Recently, the Zhuzhou branch of Hunan Expressway Group carried out energy-saving transformation of LED lighting in the Youyi and Damianshan tunnels.

The Youyi and Damianshan Tunnels are the main traffic arteries connecting Hengyang to Yanling in the north-south direction of the Zhuzhou section of G0422 Wushen Expressway. The original lighting facilities have been used for a long time and the light decay is serious. The Zhuzhou branch of Hunan Expressway Group responded positively. Implement the needs of expressway development in the new era, and standardize the brightness requirements of enhanced lighting, transitional lighting, and basic lighting at entrances and exits.

The renovation will completely dismantle the old high-pressure sodium lamps with high energy consumption, uneven brightness and high maintenance costs, and replace them with LED lighting fixtures. The traditional high-pressure sodium lamp emits "orange" light. In contrast, LED lamps have the advantages of directional light emission, low power consumption, good driving characteristics, fast response speed, high shock resistance, long service life, and environmental protection. Become a commonly used energy-saving light source in the new era,

It is reported that because it is a solid-state cold light source, LED lamps have the characteristics of environmental protection, pollution-free, low power consumption, high light efficiency, and long life. The white light source emitted is brighter and can make the passengers see when passing through the tunnel. Clearer.

The actual use data also proves that the energy consumption value of the tunnel that has completed the lighting energy saving transformation is reduced by about 56%, and the light inside the tunnel is softer and uniform, the brightness increases significantly, the tunnel outline is displayed more clearly, and the visual environment is improved more intuitively, thereby reducing driving The visual and mental fatigue of the staff. It not only eliminates visual blind spots, can further improve the safety factor, thereby reducing the incidence of traffic accidents in the tunnel, but also greatly reduces operating costs.

At present, the progress of this renovation project has been completed about 40%, and it is expected that all renovations will be completed before the end of October. Because the transportation organization of this renovation is organized and implemented in accordance with the principle of "single-frame closed construction, single-frame normal traffic". Reminder of Hunan Expressway: Slow down for construction sections.

In the next step, the Zhuzhou branch will further increase the comprehensive physical examination of bridges and tunnels in its jurisdiction, promptly deal with existing general hidden dangers, list key hidden dangers, and maintain a long-term warning effect to create a safe traffic environment for vehicles.
