Picture yourself working under the open sky – in your office. A dynamic luminous ceiling brings the sky into office spaces by creating the effect of passing clouds. Researchers from the Stuttgart-based Fraunhofer Institute for Industrial Engineering have replicated indoors a luminous ceiling that extends across the entire room, simulating lighting conditions that resemble those produced by passing clouds, and conveying the impression that you are sitting outdoors.
A combination of red, blue, green, and white LEDs is used to produce the full light spectrum. This combination makes it possible to generate more than 16 million hues. And, the white LEDs are more energy efficient than the colored lights, which keeps the energy costs to a minimum.
