South Haining, jiaxing, Hangzhou Xiaoshan, connect,Qianjiang tunnel as a provincial key projects,Much interest from the date of commencement.　

    Yesterday,This mega-River road tunnel has not yet opened,Came the good news--the Qiantang River tunnel project will be full use of LED down light,The tunnel lights in use throughout the country relatively rare.Qianjiang LED lighting in tunnel engineering works,National Semiconductor tunnel light application projects were also selected,Model is more significant.

   Qianjiang tunnel LED lamp life up to 5 up to 100,000 hours,And mercury-free, radiation-free, calorie-free, recyclable.In other words,Qianjiang tunnel LED down light can reduce 2,462 tons of carbon dioxide emissions each year,74.1 tons of sulfur dioxide emissions reduction,Reduce nitrogen dioxide emissions 37.05 tons,You can effectively improve the ecological environment of tunnel.Doing good job of environmental protection,Cost cutting expenditure is obvious:Can be saving each year of 2.47 million,Saving electricity 1.8 million Yuan.

   It is understood that the,As the tunnel than any other country in the world,Nearly 5,000 in the tunnel,Is more than more than 10 tunnels LED tunnel lights,Less than tunnels total length of one-eightieth km.This is mainly because the tunnel LED high power lighting technical specification has not yet been formed,Compared to the cost and normal fluorescent lamps and LED lamps,At a much higher rate.

  Hangzhou municipal Highway Administration related to people,Construction therefore took great effort,Invited 4 well-known manufacturers,In the six months after the experiment,Ultimate green and efficient LED light source,At present, Qiantang River crossing project is steadily advancing,Next year is expected to be open to traffic.
