Artificial Light that looks like the real deal

An Italian company CoeLux has produced a light fixture that mimics sunlight using LED and nanotechnology.

CoeLux is founded by Italian Professor Paolo Di Trapani. The LED used is calibrated to the same wavelength as sun, but to produce the effects of sunlight we are accustomed to, Professor Paolo Di Trapani had to recreate the (Rayleigh scattering) effects Earth’s atmosphere has on sun rays.  This is achieved using titanium dioxide nanoparticles combined into the light fitting’s clear polymer ‘diffuser’. The optical system of the LED incorporates realistic rendering to also create an illusion of the sun appearing a distance away.

CoeLux has products that can simulate the warm grazing light found in Scandinavian skies or the cooler and vertical light of the equatorial sun or a 45 degree light that mimics the light and shadows of the Mediterranean.

Looking from the photos, the effects CoeLux can produce certainty looks promising. There are just starting their commercial journey, so prices are expected to be steep. But with such a technology, imagine how architecture can evolve.
