A luminaire ( 1 ) is disclosed, comprising a main reflector ( 3 ) with a light emission window ( 5 ), and comprising a counter reflector ( 7 ) positioned opposite to the main reflector. Means ( 9 ) for accommodating at least one electric lamp ( 11 ) are provided in the luminaire in between the main reflector and the counter reflector. The counter reflector is provided with a light-transmitting cover ( 13 ), acting as an optical waveguide and positioned at a side ( 15 ) of the counter reflector facing away from the means ( 9 ). The cover is provided with diffusor bodies ( 21 ) which scatter the light coupled into the cover and transmitted through the bulk of the cover. Thus a desired distribution and appearance of the optical brightness of the cover is obtained.
