As one of the leading LED tunnel lighting manufacturers in China and one of the largest outdoor LED lighting products suppliers in China, Xi'an Liming works closely with Future Lighting Solutions' engineering team to ensure that the lamps produced meet the national tunnel lighting standards. At the same time, it has a sustainable LED supply. Future's services include LED components and color temperature selection, light simulation, lens testing, and advanced color temperature region subdivision to achieve the required color temperature of 5000K and provide joint inventory to ensure LED supply.
“It is Fuchang’s help in designing and optimizing these tunnel luminaires that enabled us to meet and exceed the national standards for such luminaires and win the lighting contract for these two tunnel projects,†Xi’an Liming Mu Yijing, general manager of the company, said, “There are still many tunnel construction projects under planning. With such experience, we will be in a favorable position in the bidding process for these projects.â€
These lamps are used to illuminate the Xinkailing and Wangzhuyuan No. 2 tunnels from Lu'an to Wuhan Expressway, which is a north-south branch of China's east-west traffic artery from Shanghai to Wuwei. The 4.7 km (2.9 mile) lighting project of the two tunnels was jointly completed by Xi'an Liming and Anwei Huanyu Highway Construction and Development Co., Ltd.
Each 50W and 100W tunnel light uses 42 and 72 LUXEON Rebel LEDs, respectively. In addition to energy savings, these lamps have other advantages over traditional light sources such as fluorescent lamps, metal halides, and low- and high-pressure nano lamps, such as 60,000 hours of service life and shock and vibration resistance in tunnel environments. Significantly reduced replacement, repair and personnel costs, as well as lane closure times.
The use of LED technology in this project also includes other advantages, such as better color rendering, which improves driving visibility and safety; and because the heat generated by the LED is very low, the lamp is baked and accumulated by dust and dirt. The phenomenon of yellow light is also reduced; LED lights also have a number of "environmental" features, such as meeting ROHS requirements, the structure does not contain mercury and lead.
“This installation highlights the environmental and low maintenance cost advantages of using LUXEON LEDs for tunnel lighting, as well as the ability of LEDs to provide the brightness and balanced road lighting needed for safe and comfortable driving,†Winter Lighting, Vice President, Greater China Sales, Future Lighting Solutions Chan said, "The cooperation with Xi'an Liming on this project gives us the opportunity to participate in China's important infrastructure upgrades, and also gives us the opportunity to contribute to China's energy-saving initiatives."
