ABSTRACT:
A luminaire includes a reflector in a housing, a lampholder for accommodating an electric lamp parallel to a light-emission window of the housing and to second sides thereof, and a light transmissive pane closing the window. Light-screening lamellae are present near the window, transverse to the main direction of the lamp. The luminaire has lamellae in regions adjacent first sides of the window, only; a central region of the window being free of lamellae for allowing easy replacement of the lamp through the central region not occupied by the lamellae. In an embodiment of the luminaire the lamellae are not linked to the pane. The luminaire allows for an easy replacement of the lamp and easy cleaning of the pane. An increased light output is obtained, too.
