Abstract

A specular-reflector luminaire (1) is specified, in which there are arranged perpendicularly above one another inside a main reflector (2) two fluorescent lamps (6.1, 6.2) having an auxiliary reflector (3) arranged between the fluorescent lamps (6.1, 6.2). Furthermore, transverse blades (4, 5) are provided for the purpose of achieving the required screening conditions in the longitudinal direction of the luminaire. The main reflector (2), fluorescent lamps (6.1, 6.2), auxiliary reflector (3) and transverse blades (4, 5) are dimensioned and arranged with respect to one another such that when the upper fluorescent lamp (6.1) is switched on the luminaire has the narrow-angle characteristic, and, when the lower fluorescent lamp (6.2) is switched on, a wide-angle characteristic. <IMAGE>
