LED street lighting conquers Beijing, China

LED technology in street lighting is on the advance across the world. As part of the Chinese "10 cities 10,000 lights" project, three districts in the capital Beijing were equipped with LED street luminaires by the HBTechnology CAST Group, using OSLON SSL LED by OSRAM Opto Semiconductors. They ensure that the busy streets are brightly lit and save up to 50% in energy compared with conventional luminaires.

In some parts of Beijing, LED modules for street luminaires with an output of 120W or 180W now replace the conventional 250W or 400W sodium vapour lamps. As a result, these urban districts achieve energy savings in street lighting of up to 50%. For the metropolis of Beijing with its high energy consumption, this is of great importance. In addition to energy efficiency, light quality also played a major role in the decision for conversion. Dong Cheng, Chao Yang and Da Xing are urban districts bustling with life. For that reason, excellent illumination was required to increase safety for both drivers and pedestrians.

The city planners decided in favour of the powerful OSLON SSL LED by OSRAM Opto Semiconductors. They are part of the 1-W class; with their compact size of only 3 x 3 millimetres, they are currently the smallest LED in their class and luminous efficacy on the market. Even at higher flux rates, they work reliably and efficiently. Their good color rendering index with natural appearance of colors and clearly contoured rendition of contrasts provides additional safety on Beijing's streets.
