Office Ceiling Mimics Sky
German engineering institution the Fraunhofer Institute has developed a lighting solution for interior environments that mimics natural daylight and the ever-changing nature of the sky.
Comprised of large lighting tiles that each contain 288 red, blue, green and white LEDs, the ceiling surface can generate more than 16 million different hues, allowing it to mimic the sky’s natural hues and the passing of clouds. Designed for office spaces, the project is founded on the theory that fluctuations in the intensity and hue of daylight encourage alertness, helping employees to concentrate.
Ideas similar to this are discussed in the article Spaces That Trick The Body.
