The process, patented by a Gironde-based company, is being tested on two sites with no street lighting, in order to secure access to the Saint-Lambert shooting range and campsite.

How can you see better at night without installing street lighting? That's the challenge of photoluminescent road paint. The paint glows at night, giving cyclists and pedestrians greater visibility and safety. This luminous idea, developed by the French company Olikrom, based in Gironde, is "a small revolution", according to Jonathan Gien, the new director of Millau's municipal technical center, and Bernard Grégoire, the elected representative in charge of the works.

What is photoluminescence?

Photoluminescence is a physical process whereby a material absorbs photons from a light source and re-emits them. To achieve this, the body is subjected to radiation of varying intensity, which excites the electrons present in the substance. These electrons store the light, store the energy and release it when there is a total absence of light.

Thanks to photoluminescence, the substance can be recharged indefinitely by daylight or artificial lighting. Our LuminoKrom® photoluminescent paint exploits exactly this physical phenomenon.
