LuminoKrom® paint, a renewable energy photoluminescence

From its inception, the LuminoKrom® innovation has been designed to contribute to the eco-citizen challenge of our societies. LuminoKrom® photoluminescent paint comes from ADEME’s “Route du Futur” program, the main challenge of which is to create the infrastructures of tomorrow: safer, more economical, more eco-sustainable.

LuminoKrom® luminous paint harnesses renewable energy from solar radiation. An inexhaustible source of energy, clean and without impact on greenhouse gases.

LuminoKrom® paint naturally captures sunlight during the day and restores it as luminosity all night long. Thus, without any consumption of electricity or CO2 emissions, dangerous areas such as cycle paths, baffles, roundabouts, urban furniture in a city can be marked with light.

LuminoKrom®, an asset for reducing light pollution

LuminoKrom paint was designed to provide light signage at night with minimal or no impact on light pollution: occasionally, the intensity emitted is diffuse. It is extremely weak, in the order of a few tens of millicandelas.

A comparative estimate over a kilometer of cycle path shows that the LuminoKrom® marking emits 10,000 times less light than public lighting! The impact on visual pollution of the photoluminescent marking is also very low compared to the installation of vertical lighting poles.

Today, reducing light pollution is one of the challenges for our societies. Globally, more than 80% of the world population lives under a sky marred by light pollution (source Samuel Challéat – Sauver la nuit, Premier Parallèle editions), and in Europe, 2/3 of the population can no longer see the milky way!

The consequences of excess artificial lighting go far beyond the deprivation of starry sky viewing. They are also a source of disturbance for biodiversity (modification of the prey-predator system, disturbance of reproduction cycles, migrations, etc.) and represent a considerable waste of energy.

Faced with this issue, more and more elected officials are mobilizing: modulation of public lighting or complete shutdown of neighborhoods part of the night, choice not to light certain tracks or greenways that are less used.

LuminoKrom® luminescent paints offer site managers an additional solution to secure night trips on pedestrian paths or cycle paths while limiting the impact on light pollution with regard to alternative solutions.

LuminoKrom®, an asset for partially switching off urban lighting

Lighting is not just light pollution and, in its absence, street furniture, work areas, intersections or river banks can turn into accident-prone areas for pedestrians and cyclists.

Luminous painting offers an alternative to elected officials to ensure continuity during these phases of extinction. As soon as night falls, the LuminoKrom® marking lights up and takes over without any consumption of electricity.

LuminoKrom®, rapid deployment with low environmental impact

Using LuminoKrom® light beacons to secure a dark place is extremely simple and quick to implement. The marking is applied using an Airless type machine with a speed of 2 to 4 km / hour.

The environmental impact is therefore extremely reduced with regard to the installation of public lighting which requires digging trenches, grooving the roadway for the passage of electric cables, and making bases for the vertical masts. whose aestheticism in a natural place is far from unanimous.

The low environmental impact of LuminoKrom®, the words of an elected official

In October 2018, the city of Pessac decided to secure a cycle path with the LuminoKrom® light marking. The place is not chosen at random. This is a cycle path located in a protected area that winds through a dark forest.

For Eric Martin, 1st deputy mayor of Pessac. “Some people gave up taking this cycle path and residents demanded the installation of public lighting, but it was expensive. It was the ideal place to test a less expensive solution. To light this pessacaise track, it would have been necessary to make trenches, to touch the roots of trees and to place relatively low candelabras. That was not our policy. Pessac was the first municipality of more than 50,000 inhabitants to have tested, in France, the extinction of lighting public at night “.
