Abstract
A luminaire includes at least two lamps and a main reflector whose outer edge defines a light emission window. A counter reflector is provided opposite the main reflector. Light originating from the lamps can only leave the luminaire through the light emission window after passing through a diffuser and/or a mixer which are positioned in a counter light emission window of the counter reflector and on an edge of the counter reflector, respectively. Homogeneously mixed light can thus be obtained from the luminaire when two lamps of different color temperatures are used.
