Abstract
A lighting appliance has a flat light guide and multiple light sources radiating light beams and a section for coupling-in light of the flat light guide, wherein the flat light guide has a surface for coupling-in the light beam and a deflecting surface for deflecting the coupled-in light beam toward a main section of the light guide, onto which a surface for coupling-out of light abuts in the light guiding direction, that the main section extends between the section for coupling-in of light and the surface for coupling-out of light has opposing flat sides, on which the coupled-in light beam is fully reflective in direction of the surface for coupling-out of light, wherein the surface for coupling-in of light is embodied so that the coupled-in light beam is directed under a tipping angle relative to a main radiation direction of the light source in the direction of the deflecting surface.
