Lumileds’ LUXEON Rebel LEDs illuminate bridge in Harbin, China

Future Lighting Solutions, which provides LED lighting components and support services for solid-state lighting products and installations (including engineering expertise, concept development, full system solutions and online tools), has completed a bridge lighting project in the Chinese city of Harbin using 1288 linear floodlights containing 12,000 LUXEON Rebel LEDs made by Philips Lumileds of San Jose, CA, USA.

Spanning the 1565m Songhuajiang Bridge over the Songhua River, the new lighting was designed and manufactured by Roled Opto Electronics Shanghai Co Ltd, with LEDs and solution support supplied by Future Lighting Solutions.

Roled used LUXEON Rebel LEDs in the floodlights because of their proven long-term reliability, including the ability to withstand extreme local temperatures ranging from 28°C to –24°C that have given Harbin the nickname of ‘The Ice City’. Other key considerations included the ability to run at a drive current of 700mA, reducing the LED count and associated costs required to generate the necessary light output, and assured LED supply under Future’s inventory management program.

The use of LED illumination in the project reduces energy consumption by as much as 80% and provides a lifetime of 50,000 hours that minimizes bulb replacement frequency in the difficult-to-reach bridge girders. Future Lighting Solutions assisted Roled with thermal and optical simulations as well as component recommendations, including the National Semiconductor driver used in the system design.

“The Songhuajiang Bridge is a showcase lighting project. It is in the 10 th largest city in China, and the bridge lighting can be seen at night from at least 1.5km away,” says Roled Opto Electronics’ marketing manager Derkson Liu. “Reliability is therefore essential, and Future was able to demonstrate that LUXEON Rebel LEDs met all of our performance criteria,” he adds.

“Roled’s reputation as one of the top architectural solid-state lighting designers in China literally depends on the integrity of their luminaires,” says Future Lighting Solutions' regional sales VP Winter Chan. “Their use of LUXEON technology in a demanding project like this clearly shows that LUXEON LEDs can withstand any installation environment.”
