The invention relates to an air-handling luminaire for a ring lamp (11), having a circular luminaire housing (10) around which a supply air distributor (2) is arranged in the form of an annulus. According to the invention, the jet-guiding elements (20) of this supply air distributor have a blow-out angle, open outwards, of 30 DEG to 40 DEG measured with respect to the horizontal, and are arranged such that the blow-out openings (200) of adjacent jet-guiding elements (20) have a minimum separation (E) of 40 mm. Consequently, it is possible in the case of a maximum flow of supply air to fulfil the condition for decrease and to keep the flow noise adequately low; on the other hand, stable flow conditions are guaranteed even in the case of the weakest flow of supply air. <IMAGE> |
