A luminaire, comprising a light source ( 6,7 ) for producing light radiation leaving the luminaire through its front side. The luminaire comprises a dome-like concave reflector ( 1 ) around a central axis ( 2 ) perpendicular to said front side. The luminaire comprises a tubular louver ( 11 ), being positioned around said central axis ( 2 ) in front of the light source ( 6,7 ) and being located at least partly inside said concave reflector ( 1 ). The louver ( 11 ) has a substantial tubular wall and both sides ( 12,13 ) of the wall have a light reflecting surface. The louver ( 11 ) is connected with the remainder of the luminaire through connection means ( 17 ), which are substantially located in the area of the luminaire behind the louver ( 11 ). The connection means ( 17 ) engage the louver ( 11 ) near its back edge ( 15 ), which is directed to the light source ( 6,7 ).
