Abstract

The luminaire has a housing (1) in which a first asymmetric reflector (3) and a second symmetric reflector (6) are disposed. The reflectors (3,6) have a light emission window (2) resp. a light window (7) in a plane P. The first reflector (3) has an auxiliary reflector (5) opposite means (4) for holding a tubular lamp, which extends through the light emission window (2). The luminaire is able to illuminate a wall evenly from the ceiling to which or in which it is mounted.
