Fraunhofer Institute LED light panels mimic the sky

Researchers at the Fraunhofer Institute have brought the sky indoors with a lighting solution for offices that makes a sky effect on the ceiling. It is made of LED lights which mimic natural lighting conditions, including passing clouds and different shades of blue and gray. The lights are 20-inch by 20-inch tiles, each with 288 LEDs and diffuser films. The LEDs are colored red, blue, green, and white, making them able to produce more than 16 million hues.
