364 LED lights brighten Haiyang tunnel

Is through Haiyang Granville Green high-speed highway, bear Paul Chang and promote the economic development of the city of Haiyang has the mission to ensure smooth road security, good service, ABG, recently, Yantai Wei Qing Expressway Management Office of the LED upgrade to Haiyang tunnel, before the exit of high energy consumption high pressure sodium lamp the stage of history.

With the transformation of the LED light source using multi chip integrated single module design, selection of high brightness semiconductor chip, it has high thermal conductivity, low luminous decay, pure light color, no heavy shade etc., to compensate for the lack of prior high pressure sodium lamp.

According to Wei Qing Yantai expressway management office staff Peng Chuandong introduction, the Haiyang tunnel lighting system LED upgrade adds a lot of humanized design elements, for example, according to the human eye perception changes to light, the entire lighting system is divided into entrance section, transition section, middle section, transition section and exit section, so the transformation after the end of the tunnel and the occupants eyes light perception will be more comfortable. In addition, the staff gave calculations, the actual power of newly installed 364 LED energy-saving lamps for 36.4 kilowatts, according to 0.72 yuan per kilowatt basis, 24 hours a day to open it, a year of electricity for more than 20 yuan. Before the transformation of the high pressure sodium lighting annual electricity and maintenance costs will spend more than 60 yuan, in addition, LED lamp also has a long life, short maintenance cycle, low consumption and environmental protection.
