Osram’s Golden DRAGON Oval Plus LEDs used for Zhujiang New City street lamps

Osram Opto Semiconductors GmbH of Regensburg, Germany says that the Shanghai RenMin Road Tunnel and Guangzhou Zhujiang New City in China are each using about 30,000 of its Golden DRAGON Oval Plus LEDs. “The former is anticipated to alleviate the Bund traffic in time for the World Expo 2010 while the latter, being the first in the area, will set a benchmark for the future of LED street lighting there,” says K C Cheng, marketing director for Hong Kong-based subsidiary Osram Opto Semiconductors Asia Ltd.

The firm says that its LEDs have been chosen by Guangdong Zhonglong Communications Technology Co Ltd due partly to their 50,000 hours lifetime, which extends service intervals (reducing maintenance costs and total cost of ownership). “Installation in the Shanghai RenMin Road Tunnel once again shows that LED is the most suitable light source for tunnel lamps,” comments Guangdong Zhonglong Communications Technology's general manager Chen Bin. “The uniformity of illuminance on the tunnel's road surface exceeds 0.9 while over 0.7 on the side walls,” he adds. “We also forecast that these LED-based lighting fixtures can bring 35% energy savings yearly.”

The Golden DRAGON oval Plus has been developed specifically for street and tunnel lighting, with a focus on ease of use. Due to the integrated lens, no secondary optics are required, easing the design process. The silicone lens materials also ensure long lifetime and reliable performance, says Osram Opto. Also, the oval radiation pattern directs the light to where it is needed on the road surface, achieving homogeneous illumination. 

Osram Opto says that the Chinese government's LED Lighting Program ‘10,000 lights in 10 Cities’ has generated momentum in the LED function lights market, such as street lamps, tunnel lamps, function lights for subways, gas stations and underground park areas. With many construction projects and new city districts being developed, demand for LED lighting is expected to continue to grow.
