<p>The luminaire has an elongate concave reflector (1) defining a light-emission window (2), means for receiving electrical fluorescent tubes (4, 5) and a row of lamellae (6) in the light-emission window (2). A prismatic reflector element (7) extends in the longitudinal direction of the reflector (1) and has its base (72) in the light-emission window (2) and its top (71) next to the fluorescent tubes (4, 5). The luminaire, when mounted to a ceiling, can suitably be used to illuminate vertical surfaces, while the floor is illuminated to a smaller extent only.</p> |
