OSRAM Opto Semiconductors’ Golden DRAGON Plus LEDs are being used by Guangzhou Zhonglong Communications Technology Co. Ltd for the Yangzi River Tunnel luminaire project in mainland China. With an internal diameter of 12.7m, the tunnel is 8.9km long in a twin-tunnel complex and each of the bores with 3-lane of traffic. About 5,886 tunnel luminaries with over 410,000 pieces of OSRAM Golden DRAGON Plus LEDs will be installed in two bores. The Yangzi River tunnel will be the longest in the world to have brilliant LED light.
“This project marks the new era of illumination that LED luminaries are used broadly for tunnel lighting in China. We chose OSRAM as our partner in this project because we can count on OSRAM’s expertise in LED technology by providing us high quality and reliable LEDs. Furthermore, with 40 percent to 50 percent of total energy consumption in the tunnel comes from tunnel illumination, we anticipate that the average annual energy savings of these LED-based tunnel lamps is over 35 percent,” said Bin Chen, President of Guangzhou Zhonglong.
With pressure on rising price and short supply of energy, Chinese government had begun committing in energy-concerned policies and subjects by instructing local governments to comply energy-saving status to all infrastructure development, in which LED as the road/tunnel lighting source becomes one of the focuses.
“We are proud to help move forward the energy-efficiency initiatives in China by providing LED technologies to our business partners,” said Dr. Alfred Felder, President and CEO of OSRAM Opto Semiconductors Asia Ltd. “Our cooperation with Guangzhou ZhongLong is a vital landmark for high performance LED as tunnel lamp light source in China.”
Golden DRAGON Plus LEDs offer full-color spectrum brightness and can last for up to 50,000 hours. The longer service intervals and the robust nature also attribute to LED-based tunnel luminaire by reducing maintenance costs. Furthermore, the availability of cool and warm white LED with excellent color rendering offer the flexibility to choose the color temperature range for the specific street lighting application.
