LuminoKrom photoluminescent road paint, innovation at the service of our cities

The startup OliKrom manufactures a phosphorescent road paint for road marking. This contains pigments that absorb sunlight during the day, to restore it during the night, without any electrical connection. After a first test on a cycle path, use on the road is being studied to illuminate pedestrian crossings, dangerous bends, etc.

LuminoKrom® luminous coatings have been designed to meet the challenges of safety and visibility. During the day, the light emitted by the sun makes it possible to see, to locate oneself in space, to navigate, to avoid obstacles, to recognize oneself. At night, everything is dark!

To guide himself in the dark, man first used fire (torches, candles, candelabra, etc.). Then he discovered electricity and invented the electric light bulb.

Today, LuminoKrom® technology makes it possible to create markings that light up at night without any consumption of electricity. LuminoKrom® luminescent marking can be recharged on rainy days as well as on sunny days or in the undergrowth (Measurements carried out by Gustave Eiffel University as part of the ADEME “I-Street” Program).

LuminoKrom® innovation lies in having developed photoluminescent markings that are very resistant outdoors and capable of storing the surrounding light to emit a diffuse luminosity at night, visible for more than 10 hours. This patented innovation was developed within the R&D department of OliKrom. Several years of research and collaboration with the Eiffage Group were necessary to obtain a paint conforming to road use, combining coverage, colorimetry and chemical stability with optimal luminous performance in terms of intensity and duration.

Outstanding luminescence duration

LuminoKrom, is the first photoluminescent road paint on the market capable of illuminating for 10 hours at night (Class E, ISO 17398 standard). Be careful ! There are many so-called “phosphorescent” and / or “photoluminescent” products on the market with a luminescence duration of 2 to 3 hours (class B / C). Maintaining brightness over +10 hours is essential in the road sector to ensure good visibility throughout the night.
