At first glance, CoeLux appears to be just a normal window, but flip a switch and seemingly natural sunlight starts streaming in. This innovative lighting panel, developed by Paolo di Trapani at the University of Insubria, uses nanoparticles to mimic actual daylight. The panel of white LEDs that shine through a clear plastic panel studded with nanoparticles that are invisible to the naked eye, scattering light the same way that Earth’s atmosphere does with sunlight. One caveat: it’ll cost you $68,000+ to have one installed. Click here to view more brilliant and wacky furniture designs. Continue reading for two more videos, additional pictures and information.
“By strategically peppering a clear polymer sheet with titanium dioxide nanoparticles, di Trapani and his team managed to accurately mimic the physics of Rayleigh scattering – the process by which air molecules scatter the sun’s radiation. The prototype panel, which is 5.9 feet long and 33.5 inches wide, makes use of two different sizes of nanoparticles positioned in different sections of the plastic to separate light into certain wavelengths. White light from the LED array is diffused into ‘sky-light’, where blue wavelengths are dominant, and a bright yellow spot of warm, yellowish light serves to mimic the Sun. The team has even developed different panels to simulate other outdoor light conditions – everything from a bright sunny day, to a colorful, glowing sunset,” according to Digital Trends.
