Abstract: The invention concerns a wall mounted luminaire, in particular for producing indirect light, comprising a casing (10) for fixing to a wall and a light guide device fixed to the casing (10) for guiding a preferably indirect light flux radiated from a light means. The aim is to increase the light intensity distribution beneath the light. That is achieved according to the invention in that the light guide device is mounted rotatably to the casing (10) and that there are provided means for at least partially deflecting the light flux in the rotary movement (FIG. 1).
