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.
Claims11
An indirect specular lamp, comprising:
- a channel-like shaped counter-reflector;
- a light bulb arranged within said channel-like shaped counter-reflector and completely screened by it with respect to a front region to be illuminated by the lamp;
- an at least partially curved main reflector arranged opposite said counter-reflector which is larger than said counter-reflector, said counter-reflector being positioned between said front region and said main reflector;
- said light bulb being a fluorescent tube;
- and
- said counter-reflector being provided with cross-lamellae means at least partially surrounding said light bulb for screening said light bulb in a longitudinal direction of the light bulb.
An indirect specular lamp, comprising:
- a counter-reflector;
- a light bulb arranged within said counter-reflector and completely screened by it with respect to a front illumination region of the lamp;
- an at least partially curved main reflector arranged opposite said counter-reflector which is larger than said counter-reflector and which faces the illumination region;
- said light bulb being a fluorescent tube;
- said counter-reflector having a channel-like shape and being provided with cross-lamellae means surrounding said light bulb for screening said light bulb in a longitudinal direction of the light bulb and perpendicular to a direction from the counter-reflector to the illumination region;
- and
- a cross-sectional generated surface of said main reflector being mirror-symmetric relative to a center plane through said fluorescent tube and running along the longitudinal direction of said light bulb.
