Expercité : the Delandine vault lighting designed for the City of Lyon wins a Concours Lumières award.

Energy Division

The Delandine vault is a 90-metre road tunnel located under Lyon Perrache Station’s switching area, and is among the Concours Lumières’ 2020 winners, for the lighting work carried out by our electricians. This competition rewards three remarkable sites per year, taking into account the facilities’ energy efficiency and environmental integration.  

The vaulted passage is used every day by the citizens of Lyon, and includes a one-way traffic lane, two cycle paths, several adjoining parking spaces and two pavements. Yet it is not quite like other tunnels! At nightfall, the white zenithal lighting makes way for a tangle of bright lines, spaced 1.435 m apart like railway tracks. This luminous switching was chosen by the City of Lyon and created by lighting designer Jérôme Donna. It shines until midnight during the week and one o’clock in the morning at weekends, and is then replaced by more sober, functional lighting until dawn.  

“Works supervisor Ludovic Galaman and electrician-fitter Amaury Dumond integrated one straight rail into the vault and fixed it, so as to conceal the power supply cables, drivers used to control the lighting system and light fixture fixings. They fitted a total of 42 iGuzzini full-LED 360° Tricks with light blade effect, and 21 Lightscan projectors by Erco for the functional lighting” said business manager Guillaume Roy, in charge of the project.  

This artistic lighting created and installed in 2019 won third prize in the 2020 Concours Lumières. The competition has been organized every year since 1987 by the SERCE, a professional organization representing companies involved in energy and digital transformation in France, in partnership with Signify (formerly Philips Lighting).
