Abstract
The luminaire for a tubular electric lamp (3) has, in a housing (1) with a light emission window (2) in plane P, reflectors (5) at either side of the lamp (3) and a number of slats (10) transverse to the reflectors (5) below the lamp (3). The slats (10) are V-shaped in cross-section and have an inner surface (11) facing the lamp (3). The inner surface (11) has a central zone (12) and flanks (13) which extend at an angle away from plane P. The inner surface (11) has end zones (14) near the reflectors (5) which are in a plane Q parallel to plane P. The longitudinal axis (4) of the lamp (3) is situated in a region extending from plane Q towards plane P. Although the slats are relatively small, bright spots within the shielding angle of the luminaire are avoided.
