Anolis helps re-light Gerland Park in Lyon
- Details
Gerland is a dynamic residential area that has also become a hub for emerging tech companies and commerce and a hotspot for sports and entertainment events with several world-class venues located in its 7th arrondissement catchment area.
Lighting designer Laurent Fachard, founder of Les Éclairagistes Associés (LEA), has worked extensively in and around this area, and recently two of his key landscape lighting projects were updated with new LED technology that had subsequently come to the market.
The new Anolis lighting authentically replicates his original illuminated art, simultaneously making these landmark urban lighting designs more energy efficient and sustainable.
The two areas that have been re-lit using the Anolis fixtures are the Chromatic Garden in Gerland Park, running adjacent to the river Rhône, and a landscaped roundabout on the Place des Docteurs Mérieux, part of the major road gateway into the city of Lyon.
The job of completing this diligent and meticulous task fell to Thierry Marsick, head of the city of Lyon's urban lighting department (DEU), who commented, “With LEDs coming onstream, apart from the energy efficiency, it was also an opportunity for us to utilise fixtures with much finer colour control and tuning”.
A main requirement for the new luminaires was to reproduce the original lighting scheme colours, including some – like yellow – which can be a challenge for LEDs!
They also wanted to be able to focus the lights to obtain tight beams whilst maintaining maximum luminous flux.
“We really needed to understand what tools were available to help us achieve this goal,” commented Frédéric Flacher, the DEU office project manager responsible for the works, who was assisted by Jérôme Donna.
As their search for suitable technologies began, they also decided they wanted one type of luminaire that would fulfil all these multiple criteria and they chose the Anolis ArcPar 150.
The decision came following several options initially considered and extensive testing into exactly how to re-light both areas.
They appreciated the fact that as an IP65 floodlight, the ArcPar 150 has a 3.8° to 60° optical system, which is ideal for both spot lighting and for illuminating larger areas.
The RGBA colour mix – red, green, blue, and amber – provides up to 1,676 lumens with 7 x 40 W multichip LEDs achieving a total of 220W of power consumption compared to 430W drawn by the previous metal halide lighting – representing an impressive energy saving of 51% for this architectural lighting!
Bruno François, head of the architectural department at Anolis France, commented, "The ArcPar 150 uses an optical train like the stage version, so the LED PCB does not move. Only the lens moves forward or backward to open the light beam.”
Laurent Fachard’s architectural and landscape lighting for Gerland Park transforms it into a "chromatic garden" at night. Seven colours of light are used: mauve, red, orange, yellow, green, blue, and violet. Coloured shadows and textures shift and change in harmony with the plants and the transitioning seasons.
In the new lighting scheme, 80 x Anolis ArcPar 150 Outdoor spotlights are installed which were supplied by Saint-Genis-Laval based Anolis distributor, Tech'Lux, in collaboration with installer SPIE which is also in Lyon.
To highlight the roundabout site, LEA proposed creating an ‘impressionist painting’ visible at 360° with blue functional lighting detailing the roundabout ring, a picture now achieved using 22 x Anolis ArcPar 150 Outdoor floodlights.
The central reservation features rich coloured landscape lighting. Two high ‘needle masts’ are installed at the rotation axes of the ‘arena’, they once housed a cluster of circular discharge floodlights with dichroic glass filters and different optics and now host the Anolis ArcPar 150s.
