Luyao Zhong, deputy chief engineer of the provincial Department of Transportation to attend the sessions, the State is implementing a conservation and development of bothenergy development strategy of giving priority to conservation. In recent years, Zhejiangtransport sector is no exception, led street lighting retrofit, the provincial Department of Transportation specially formulated six special action of the action of traffic five of Ecological transportationenergy saving, led high bay, clear Zhejiang transportation “12” circular economy energy savingplanning to identify the various tasks. In recent years, the proportion of the total socialenergy consumption of transportation energy consumption of about 8%, led street lighting retrofit, and theZhejiang Province in 2007 5.85% 2008 6.02% 2009 5.64% are well below the national average.
According to the program objectives to 2015, Zhejiang Province, per kilometer of roadtunnel lighting energy consumption than in 2010, down 15 percent, save energyequivalent to 04,500 tons of standard coal and reduce carbon dioxide emissions by11,000 tons. To this end, led street lighting retrofit, the transport sector specifically to increase the exchange ofapplication and promotion of the new technology of tunnel lighting.
Led by the highway department of provincial and municipal levels, and lasted six years of research and development of the intelligent dual-controlled road tunnel lighting energy saving control system “in the practice of the 49 provincial highway Lishui cold watertunnel lighting energy efficiency of LED lights program more than 60 percent, led street lighting retrofit, economic and social benefits are very obvious. Delegates also toured the working process of the system. Its core technology is the minimum brightness of the lighting are set when thetraffic situation outside of real-time acquisition of natural light and the tunnel control the degree of adjustment to match the brightness of the lighting when the adoption of the carinside the tunnel, according to the natural light outside the tunnel, car-free through .
