An artificial light called the CoeLux is making it possible to have daylight anytime. Through a scientific process designed to replicate the sun, the amazing skylight appears to feature crystal blue skies and adds an illusion of depth with the addition of a sun gazing in from above.
The setup utilizes high-tech LEDs to provide sunlight for places which are "boxed in" from the outside while also recreating the illusion of an atmosphere. The scientists who invented the CoeLux discovered how to use a thin coating of nanoparticles to accurately replicate both the sun and temperature through the sky in an effect known as Rayleigh scattering.
