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 700 mA, thereby 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 50,000-hour lifetime 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 driver used in the system design.
"The Songhuajiang Bridge is a showcase lighting project. It's in the 10th largest city in China, and the bridge
lighting can be seen at night from at least 1.5 kilometers away,” said Derkson Liu, Marketing Manager for
Roled Opto Electronics. “Reliability is therefore essential, and Future was able to demonstrate that LUXEON
Rebel LEDs met all of our performance criteria.”
