The present invention relates to a louvred lighting fixture fitted with a bar-shaped fluorescent lamp, in which the fluorescent lamp is arranged centrally in the upper region of a box-shaped lighting fixture housing (10) of relatively large extent in width. The light exit opening is essentially subdivided into three panels of the same width, that is to say a central region (10a), which is bounded by two contoured reflectors (14) extending in the longitudinal direction. The two side panels (10b) are bounded in each case by a contoured reflector (14) and a reflector (13) extending in the longitudinal direction, which in each case extends in a curved manner over a corner region into the vicinity of a housing ceiling (11). The panels are subdivided in the transverse direction by numerous cross vanes consisting, in each case, of two parabolic branches in a V-shaped arrangement, the cross vanes (15) being arranged parallel to the ceiling in the central panel, and the cross vanes (16) being arranged approximately in the diagonal direction in the side panels. Owing to the arrangement of the reflectors, in the lighting fixture according to the invention a portion of the light flux exits in a primary fashion and a portion exits in a secondary fashion, a glare suppression of the light fluxes being achieved by the cross vanes in all panels. …<IMAGE>… |
