Slender West Lake Tunnel 1024 complete sets of LED lights installed

　　September 8, reporters learned in the Slender West Lake tunnel visits, lower asphalt paving on the tunnel has been completed, the installation of lighting has also been all over. In addition, a "black hole" effect when the tunnel entrances also install high-pressure sodium lamp, preventing the driver out of the tunnel.

　　Internal tunnel lighting safety is an important consideration engineering experts. Reporters saw the 8th interview in the tunnel, the walls on both sides of the tunnel, at intervals not far to install a set of lights, soft lights illuminated evenly on the ground.

　　Slender West Lake tunnel length of 3.6 kilometers, of which 1.2 km long main tunnel. To ensure the driver traffic safety, the Slender West Lake Tunnel lighting is energy-efficient LED energy-saving lamps, not only energy, but also uniform illumination, better lighting effects, the power of 45 watts. Calculated based on the illumination and light uniformity, lighting interval of about 9 meters, down two tunnels were installed 1024 sets.

　　It is understood that due to the strong light in the entrance, inside and outside the tunnel to allow the driver to adapt to the environment, so that the line of sight "smooth transition" instead of a "black hole" effect, construction workers also installed a high pressure sodium lamp tunnel entrance, strong fill light.
