Reportedly, Dongguan Kingsun Optoelectronics Co. Ltd recently completed the retrofit of high-pressure sodium lamps and light fixtures with 98W LUXEON LED based luminaires from Philips Lumileds on Dongjiang Main Road in Dongguan City, China.
Totally, over 2,000 LUXEON Rebel LEDs were used to replace old lamps. Therefore, this 52km stretch is the world’s longest stretch of road illuminated by LED lights to date.
It’s said that this project began as an open tender called for by the municipal government. And the tender was open to bids in June, 2010. After evaluation by the authorities, Kingsun Optoelectronics was awarded the tender and has completed the project in August.
This system includes testing and alert functions, so that if any lamp does not function as it should, the system will alert notifications immediately. The exact location, and fault description of the affected unit are clearly displayed on the system. The system is also able to support stepless, time-sharing control which allows for the adjustment of the amount of illumination based on different time periods throughout the night, and according to road conditions.
