Illuminatable device consisting of one or more LEDs and a light scattering cover

摘要

An illuminatable device consisting of one or more LEDs emitting monochromatic light, and a light-scattering cover is disclosed. The device permits optically about the same colour impression under incident light, such as daylight, as under transmitted lighting. To achieve this requirement the light-scattering cover has a transmission (DIN 5036) of at least 35% and a reflection (DIN 5036) of at least 15% at the wavelength of the relative energy maximum of the LED light source.
