Abstract

The specular lamp or lighting fixture comprises a fluorescent tube as a light bulb which is arranged largely within a channel-shaped counter-reflector. Cross-lamellae for blanking the light of the fluorescent tube out in the longitudinal direction are seated on the counter-reflector. A channel-shaped main reflector which is designed large, and whose surface is preferably matted, is situated opposite the counter-reflector. A uniform luminance in the radiation region and a compact structure are achieved with the specular lamp. The luminance does not exceed a prescribed value in a prescribed, screened region.
