The luminaire has a housing (I) with a light emission window (2), means (3) for accommodating a tubular lamp (4) in it along the window (2) and in a plane P perpendicular to said window, side reflectors (5), and three-dimensional lamellae (10) which each have an outer (11) edge and an inner edges (12). The outer edge (11) of each lamella (10) is concave. The luminaire thus has an optimized cut-off angle, screening light which would otherwise be dazzling, but permitting non-dazzling light to pass. The lamellae have a concave curvature parallel to plane P which flattens out from plane P towards the side-reflectors (5), thereby enlarging the aperture through which light emanates and making the illumination by the luminaire more uniform. |
