Zhejiang Qianjiang tunnel full use of LED lighting demonstration significance

From Hangzhou city of Zhejiang Province Highway Management Bureau was informed that, at present, Zhejiang province key project of Qianjiang tunnel is steadily, tunnel shield has been Qiantang River south through the eastern levee, is about to enter the work well, heading to complete the whole eastern tunnel. It is worth mentioning that the entire Qianjiang tunnel project will be the full use of LED (semiconductor) lighting. Qianjiang tunnel project LED lighting project, as the country's only large flow of underwater tunnel semiconductor lighting demonstration project, selected national semiconductor tunnel lamp application projects. At present, the west side of the Qianjiang tunnel is installing LED lighting fixtures.

18 test select the best LED lamp

Qianjiang tunnel length of 4450 meters, the East and West tunnel tunnel will be the installation of 2 LED lamps, has completed a unilateral Qianjiang west line LED lamp installation, LED lamp on the other side of the West installation work has been completed 3810 meters, accounting for LED of the tunnel lighting installation of the whole project amount of 48%, running in good condition.

According to reports, Qianjiang tunnel LED lighting quality requirements are very high. Due to the fact that there has not been the tunnel technical specification for high power LED lighting, so Qianjiang tunnel builders thought of a way to invite 4 domestic well-known LED lighting manufacturers in the tunnel within 200 meters, with half the time, 24 hours of uninterrupted lighting alignment, and through the 18 routine tests, test, illumination brightness contrast test, select the best illumination manufacturer, to ensure the quality of tunnel lighting equipment.

More than 80% energy saving than traditional light source

The LED lighting section of Qianjiang tunnel, including the light transition section, the buried section illumination and the circular tunnel Duan Zhaoming. In view of the characteristics of 24 hours uninterrupted lighting in the tunnel, the tunnel adopts a green, efficient, long-life LED light source. According to reports, this semiconductor light source can reduce light pollution, and the establishment of high quality and efficient, economical and comfortable, safe and reliable tunnel lighting environment.

According to reports, Qianjiang tunnel LED lighting more than 80% of the energy saving than the traditional light source, and the service life of up to 50 thousand hours to 100 thousand hours, and no mercury, no radiation, no heat, recyclable, environmental effects. According to estimates, by using LED lighting, can save electricity 2 million 470 thousand degrees per year, saving electricity costs $1 million 800 thousand, with significant economic benefits; at the same time, can greatly reduce carbon dioxide, sulfur dioxide, nitrogen dioxide emissions.

Great demonstration significance

National Development and Reform Commission, Ministry of housing and urban rural development, Ministry of transport in 2010 organized a demonstration project of semiconductor lighting products. Qianjiang tunnel semiconductor lighting product application demonstration project, as the only large flow of water tunnel under the semiconductor lighting demonstration project, selected semiconductor tunnel lamp application project.

It is understood that China is the world's largest tunnel in the country, nearly 5000 tunnels in the country, only more than more than 10 tunnels using LED tunnel lights, the number of kilometers less than the total length of the tunnel by 1/80. The LED lighting demonstration project of Qianjiang tunnel is of great significance to the popularization and application of semiconductor lighting products in china.
