Navanshu Agarwal writes that Italian scientists have developed an artificial LED sunlight system that looks just like real daylight streaming through a skylight. The LED skylight uses a thin coating of nanoparticles to recreate the effect that makes the sky blue, known as Rayleigh Scattering that doesn’t just light up a room but produces the texture and feel of sunlight. Paolo Di Trapani, one of the scientists who worked on the device believes that the skylight will allow developers of the future to not just build up, but also far down below the ground- without any of the "dinginess" that currently keeps us above ground.
CoeLux hopes to treat seasonal affective disorder, or SAD. Each year, some 10 million Americans, mostly women, find themselves sinking into a heavy malaise during the wintertime. CoeLux hopes its LED bulbs, which create the illusion of infinitely tall, bright blue skies, will help trick the brains of people with SAD, ridding them of their blues.
