This invention relates to a luminaire (106), which has a housing (103) with an opening (111) at a light output side, a reflector (105) mounted in the housing, and facing the light output side, a louver (107) mounted at the opening of the housing, and LEDs (109) mounted in the louver, such that the emitted LED light exits the luminaire only after reflection against the reflector, thereby providing indirect light output. |
