Bridge’s All-White Light Show Driven by LUXEON-Based LED Fixtures

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.
