Abstract:
1. A luminaire, having a plate-shaped optical waveguide, first illuminants, arranged on one or more narrow sides of the optical waveguide and designed to couple light into the plate-shaped optical waveguide, the light coupled into the optical waveguide being emitted via a flat side of the optical waveguide in a first radiating direction of the luminaire, wherein the first illuminants comprise multiple LEDs, the luminaire further comprising second illuminants and a reflector arrangement which is associated with the second illuminants, and via which reflector arrangement the light of the second illuminants is emitted in a second radiating direction opposite to the first radiating direction, and the narrow sides of the plate-shaped optical waveguide, to which the light of the first illuminants is coupled each form, directly in front of each LED, a pyramid-shaped structure with an inwardly curved peak for coupling the light in evenly.
