Qianjiang tunnel enabled LED lighting can save 1 million 800 thousand electricity per year

Hangzhou to the South Xiaoshan, North Jiaxing Haining Qianjiang tunnel, as the provincial key projects, has attracted much attention since the commencement date.

Yesterday, this large cross river highway tunnel has not yet opened, it came to a good news - the entire Qianjiang tunnel project will be the whole process of LED lighting, which is relatively rare in the use of national tunnel lighting. Qianjiang tunnel engineering LED lighting project, but also selected the national semiconductor tunnel lamp application projects, demonstration significance is more significant.

The service life of the LED lamp of the Qianjiang tunnel can reach 5 to 100 thousand hours, and the utility model has the advantages of no mercury, no radiation, no heat, and can be recycled. In other words, the use of the LED light Qianjiang tunnel can reduce carbon dioxide emissions by 2462 tons per year, reduce sulfur dioxide emissions by 74.1 tons, reduce nitrogen dioxide emissions by 37.05 tons, can effectively improve the ecological environment of the tunnel. Environmental protection has done well, the cost is more obvious: 2 million 470 thousand degrees per year can save electricity, save electricity costs $1 million 800 thousand.

It is understood that, as the world's largest tunnel in the country, nearly 5000 tunnels in China, only more than 10 tunnels using LED tunnel lights, the application of less than the total length of the tunnel 1/80. This is mainly because the tunnel with LED high-power lighting technical specifications have not yet been formed, and the cost of LED lamps and ordinary fluorescent lamps, compared to many.

Hangzhou Highway Authority stakeholders, the construction side has spent a lot of effort, invited 4 well-known manufacturers, after six months of the experiment, the final use of green, efficient LED light source.

At present, the Qianjiang tunnel project is steadily advancing, is expected to open next year.
