China recently completed its largest highway lighting upgrade with more than 10,000 street lights featuring more than a million Cree XLamp XP-G and XP-E High Efficiency White (HEW) LEDs. The Shenzhen highway project includes nearly 75 miles of roadways, with LED fixtures installed along one tunnel and four highways.
The LED street lighting installation was a key component of the 2011 Summer Universidade, an international multi-sport event, organized for university athletes by the International University Sports Federation (FISU), hosted by Shenzhen in August.
In compliance with China’s stringent roadway lighting requirements for light efficacy, brightness, luminance, heat dissipation, and service lifespan, Kingsun Optoelectronic Co. Ltd., a leading LED lighting company in China, selected Cree LEDs to illuminate Jihe highway number G15, Nanguang highway number G9411, Longda highway number S318, Yanba highway, as well as the Dameisha Tunnel.
Kingsun installed 270W and 300W RL2R Apollo LED luminaires alongside the highways, including three traffic lanes and an emergency lane in each direction. The installation was designed to average more than 20 lx, the national standard for main roads illumination. Kingsun anticipates a 60% reduction in energy consumption compared to the replaced, high pressure sodium fixtures.
“In large-scale lighting deployments like the Shenzhen Highway Project, where lumen output and efficacy are both essential and required, LED lighting is the ideal solution,” said Tang Guoqing, general manager of Cree China Sales. “Cree’s broad portfolio of XLamp LEDs was selected for this demanding project because they are highly efficient and have been proven to reduce overall system costs.”
