Currently, Osram Opto Semiconductors’s OSLON SSL LEDs have been installed in solar-powered street lamps to stand up to the harsh near-desert climate conditions of Ningxia, China.

The 174 new street lamps line the 2.6km of Da Xue Road in Shizhuishan City. Due to the city is close to the Gobi Desert, with an average of 28 days of fine weather per month and great temperature difference between day and night, the local government has decided to use solar energy to power the new street lamps.

 According to Xin-jun Dang, managing director of street-lamp installer GBT Technologies (Shenzhen) Ltd, “By using solar energy alone, the street lamps need to be of very low power consumption. With Osram’s OSLON SSL LED as light source, our solar-powered street lamps are estimated to save more than RMB300,000 per year in energy cost alone and reduce carbon dioxide emission by more than 53 tons annually,” he adds. “We are pleased to work with Osram, which provides an excellent application support to us. As the weather conditions are rather extreme, Osram’s LED simulation reports also help us make improvements to the designs before the fixtures are installed.”
