Can be wireless dimming: Dalian road tunnel Eastern test LED lights installed

Dalian road tunnel is located between the Yangpu bridge and Yanan road tunnel, a total investment of 1 billion 655 million yuan; the tunnel length of 2.5 kilometers, consisting of two two-way four lane tunnel with a diameter of 11 meters, the design of vehicle speed for 40km/h traffic, 4.5 meters in height. Dalian road tunnel opened in Yangpu Puxi, Hongkou river through Pudong New Area shortcut, is China's first Underriver tunnel.

According to the energy saving and emission reduction, building green tunnel, Dalian road tunnel as a pilot unit participated in the diplomatic relations committee, bureau of highways, tunnels, tunnel design institute, Fudan University, lighting engineering department and other parties involved in the establishment of "LED lighting application technology of tunnel guidance" working group.

At present, the Dalian road tunnel has been installed in the middle part of the eastern route tunnel. It is reported that, compared to the traditional street lamp, LED street lamp has the advantages of energy saving, controllable, long life. Under the traditional street lights, road surveillance cameras can shoot a lot of black, but once installed on the LED street lamp, the camera becomes very clear.

The use of LED lights is the trend of the tunnel, but at this stage, there are still many uncertainties in the actual use of this technology. The researchers found that the LED street lamp luminous efficiency still needs to be improved, it is difficult to overcome the high temperature, dust pollution and other harsh environment, high cost problems.

Concerned that the application of LED lighting technology in the Dalian road tunnel, has been regarded as one of the important technical reserves for the day, after the other tunnel further promotion, pushed for reference.
