Bridge’s All-White Light Show Driven by LUXEON-Based LED Fixtures
News Release from:
Philips Lumileds Lighting Company
17 December 2010
An all-white interactive LED light show that plays nightly on the curvy sunroof of a pedestrian bridge in the former Soviet Union is powered by 1,208 custom LED fixtures containing 6,040 high-power LUXEON Rebel LEDs from Philips Lumileds. The fixtures were designed and built by Netherlands-based Primo Exposures and RENA Electronica, with all LEDs supplied by Future Lighting Solutions in the required 4200K color temperature range in just two weeks to ensure critical color uniformity.
The Bridge of Peace in Tbisli, Georgia – a city of 1.5 million – was designed by Italian architect Michele De Lucchi with a lighting design created by France’s Philippe Martinaud. The bridge structure was built in Italy and shipped to Tbilisi in 200 trucks. The lighting was installed on site in Georgia as the bridge was being assembled.
The luminaires in the roof were built to order by RENA – based on that company’s configurable Vincent Ledline fixture design – with five cool white LUXEON Rebel LEDs per module, a Carclo elliptical beam optic, and a patent-pending louver system designed by Primo to direct the beam as well as conceal the point source.
RENA’s customizable off-the-shelf design offered rapid delivery that met Tbilisi’s tight timeline, a small footprint enabled by the compact LUXEON Rebel package, and proprietary two-wire power/data connectivity that expedited installation by eliminating three additional wires typically required for power and communication.
Each of the 1,208 fixtures in the sunroof represents its own dimmable DMX channel and is programmed through a control interface designed by RENA. The finished fixtures play four different lighting programs every hour from 90 minutes before sunset until 90 minutes after sunrise, illuminating the Mtkvari River in a dance of 21st century light that serves striking counterpoint to the historic buildings on either bank.
