New Artificial Light Mimics Sunlight

Artificial light that mimics the colour spectrum of natural sunlight is often considered as the Holy Grail of lighting technology. One company may be closer to reaching that goal. 

Access to natural daylight has long been one of the biggest limiting factors in building design – some solutions involve reflecting real daylight from the outdoors, but until now no solution has been able to mimic natural refraction processes and fool our minds into thinking we are surrounded by actual sunlight. Developed by CoeLux in Italy, this new form of artificial light is able to dupe humans, cameras and computers alike using a thin coating of nanoparticules to simulate

Rayleigh scattering, a natural process that takes place in Earth’s atmosphere causing diffuse sky radiation. Far beyond simply making lights brighter or bluer, this approach accurately replicates how miles of atmosphere transform light within just a few millimeters of surface space. Professor Paolo Di Trapani of Italy’s University of Insubria has so far spent over 10 years working on this system.
