Abstract (en)
[origin: EP0217323A2] Lighting fixture for direct and indirect lighting for a room or area of a room in a building or the like. Arranged in the lighting fixture housing is at least one reflector opposite whose reflecting topside, which is directed towards the upper light exit aperture of the lighting fixture, at least one lamp of this lighting fixture is arranged. A lower light exit aperture having a transparent lower cover which diffusely scatters the light is present on the underside of the housing. A small proportion of the useful light flux that can be emitted by the at least one lamp of this lighting fixture can be emitted through the lower light exit aperture, this lighting fixture thereby causing fewer interfering reflexes on parts of work places or the like which it illuminates and which reflect specularly. <IMAGE>
