Abstract
The luminaire and the lamellae louver () have lamellae () which enclose an acute angle δ with a main plane S. The lamellae () may have a kink () in plane S, and additional kinks () laterally of the plane S. The lamellae () prevent glare in plane S and in surrounding planes and thereby allow the luminaire to meet the Unified Glare Rating.
