More than 1.9 million LED lights were recently installed in over 20,000 street lights the Beibei district of Chongqing, China in the country’s largest municipal intelligent lighting control project, which includes nearly 16 miles of highway, 119 streets, and one tunnel.
Officials estimate the installation will result in annual maintenance and electricity savings of more than RMB 19.5 million (approximately USD 3 million) and 17.6 million kWh.
The lights were installed with 1.9 million Cree XLamp XP-E and XP-G LEDs in an effort to improve living conditions for local citizens and to meet China’s stringent roadway lighting requirements for light efficacy, brightness, luminance, heat dissipation, and service lifespan.
Replacing antiquated sodium-vapor street lighting along the Yuwu Highway, extending from Chongqing to Wusheng, the street lights were fitted with Cree XLamp LEDs and engineered by Chongqing Silian Optoelectronics Science and Technology Corporation (Silian), a leading LED lighting company in China.
Silian were the developers and manufacturers of the new intelligent light control system which features an advanced wireless network management system that uses sensors to detect light issues and adjust the brightness of the LED street lights in accordance with vehicle and pedestrian flow.
“We are very pleased with the performance of Cree’s XLamp LEDs in our luminaire systems,” said David Reid, chief operating officer, Silian. “Cree LEDs emit high-quality light with low heat dissipation that meets China’s lighting standards while saving the municipality millions of Renmenbi.”
“Cree LEDs are perfect for large-scale lighting projects such as the Beibei District installation,” said Tang Guoqing, senior advisor, Cree Hong Kong Limited. “Designed to last more than 50,000 hours, Cree XLamp LEDs offer the high efficiency and easy integration with intelligent lighting systems needed to reduce overall costs while providing beautiful light.”
