Siemens helps China with '10 cities 10,000 lights'

As part of the Chinese “10 cities 10,000 lights” project, three districts in the capital Beijing have been equipped with LED street luminaires by the HBTechnology CAST Group, using OSLON SSL LED by OSRAM Opto Semiconductors. The new fixtures ensure that busy streets are brightly lit while saving up to 50 per cent 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 per cent. 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.
