China’s largest municipal street lighting project shines with 1.9m Cree LEDs

LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA says that the Beibei district of Chongqing, China has installed more than 20,000 street lights featuring 1.9m Cree XLamp XP-E and XP-G LEDs. The country’s largest municipal intelligent lighting control project began in July 2011, and includes nearly 16 miles of highway, with Cree LED-based luminaires installed along 119 streets and one tunnel. It is estimated that the installation will result in annual maintenance and electricity savings of more than RMB 19.5m (approximately USD 3m) and 17.6 million kWh.

Engineered by China-based LED lighting firm Chongqing Silian Optoelectronics Science and Technology Corporation (Silian), the new street lights replace sodium-vapor lighting along the Yuwu Highway, extending from Chongqing to Wusheng. Silian developed and manufactured the intelligent lighting control system, which features an advanced wireless network management system that detects lighting issues with sensors and can adjust the brightness of the LED street lights in accordance with vehicle and pedestrian traffic 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.”
