Streetlights along the Yuwu Highway have been upgraded using Cree XLamp LEDs
LED manufacturer Cree has provided LED technology for a major streetlighting upgrade in Chongqing,China.
More than 20,000 streetlights featuring Cree's XLamp LEDs have been installed in the Beibei district.The project began in July 2011 and includes nearly 16 miles of highway,with Cree LED-based luminaires installed along 119 streets and one tunnel.
The company claims that the upgrade will result in annual maintenance and electricity saving of more than RMB 19.5 million and 17.6 million kWh.
Silan Optoelectronics Science and Technology Corporation,a Chinese LED lighting company,was responsible for engineering the new streetlights.The lighting system replaced sodium-vapor street lighting along the Yuwu Highway,extending from Chongqing to Wusheng.
Silan developed and manufactured the lighting control system,which includes a wireless network management system that detects lighting issues with sensors and adjusts the brightness of the lights according to vehicle and pedestrian flow.
The Municipal Bureau of the Beibei District initiated the lighting upgrade to improve the living environment for local citizens and to meet China's stringent roadway lighting requirements.
