A luminaire has a plurality of reflecting lamellae between side reflectors. The lamellae each have an outer edge, an inner surface facing away from the outer edge, and a plane of symmetry through the outer edge and the inner surface. The lamellae have a resin body and a recess in the inner surface, in the plane of symmetry. The recess has a bottom surface transverse to the plane of symmetry and substantially parallel walls along said plane. The recess may widen stepwise from the bottom plane towards the inner surface. The lamellae, as compared with metal lamellae, provide a greater freedom to choose their shape and are less expensive. They nevertheless avoid the occurrence of reflections on the side reflectors, which cause unpleasant bright spots within the cut-off angle of the luminaire. A lamellae grid suitable for the luminaire has strips interconnecting, and integral with, the lamellae. |
