Yangtze River Tunnel interior decoration for the first time using LED lighting

Shanghai Yangtze River tunnel has entered the equipment installation and interior decoration construction, which use a lot of new technologies, new materials, perhaps in the future you drive into the Yangtze River tunnel, will feel the eyes bright, because the interior is used with different lighting and other tunnels LED light source.

In February 22nd, from the Shanghai Yangtze River Tunnel LED lighting and lighting technology requirements review meeting was informed that the Shanghai Yangtze River tunnel lighting using LED light source, the relevant program has been approved by experts. It is reported that this is the first use of LED light source as an internal lighting tunnel, the use of this new light source, can reduce energy consumption by 30%, but also reduce the emissions of carbon dioxide and sulfur dioxide.

Shanghai Yangtze River Tunnel Lighting mainly includes the entrance lighting and the middle section of the lighting, with a total length of 8.1 km. According to the Shanghai Yangtze River Tunnel and bridge tunnel project construction headquarters chief engineer Liu Qianwei introduction, due to the length of the tunnel, and requires 24 hours of uninterrupted lighting, lighting load accounted for the entire energy consumption proportion of 40%-50% in the tunnel operation, become "energy hungry", while the use of LED lighting can reduce energy consumption by 30%. "If the Yangtze River Tunnel in accordance with the ordinary fluorescent lighting, power of 989 kilowatts, 24 hours off, a skylight lighting electricity to more than 20 thousand degrees, while the use of LED lighting, power consumption is 30 percent off, as long as more than 10 thousand degrees. "

It is reported that after the formation of the Yangtze River Tunnel LED lighting technical standards and system design, this technology is also expected to be extended to other tunnels.
