< Topic >When it sterilizes or sterilizes the bacterium and the virus etc which, float in the air with the ultraviolet ray and functioning it does as an ultraviolet sterilization device simultaneously, are shown collectively the illumination and the air cleaner which function with the visible light as a lighting fitting are offered.SolutionsThe ultraviolet lamp the ultraviolet radiation section where emits the ultraviolet ray of 5 which emits the electromagnetic wave which includes the ultraviolet ray and the ultraviolet lamp it covers part at least and the ultraviolet ray the ultraviolet ray reverse clipping resin component which prevents the fact that it is irradiated directly vis-a-vis the person and, it provides. The ultraviolet ray reverse clipping resin component as it cuts off or absorbs the ultraviolet ray which is emitted from ultraviolet lamp 5 has the ultraviolet ray non- transmitted visible light transmitted section which makes the visible light emit, with the ultraviolet lamp and the ultraviolet ray reverse clipping resin component, the air around the ultraviolet radiation section provides the air canal 68 which is movement possible. As it sterilizes or sterilizes the bacterium and the virus etc in the air by applying the ultraviolet ray to the air which moves that air canal, it uses the visible light which transmits the ultraviolet ray non- transmitted visible light transmitted section as illumination light.【課題】空気中に浮遊する細菌やウイルス等を紫外線により殺菌あるいは滅菌し紫外線殺菌装置として機能すると同時に、可視光線により照明器具としての機能も併せて発揮する照明兼空気清浄器を提供する。【解決手段】紫外線を含む電磁波を放射する紫外線ランプ5と、紫外線ランプの紫外線を放射する紫外線放射部の少なくとも一部を覆い紫外線が人に対して直接照射されるのを防止する紫外線遮蔽樹脂部材と、を設ける。紫外線遮蔽樹脂部材は、紫外線ランプ5から放射される紫外線を遮断又は吸収すると共に可視光線を放射させる紫外線不透過・可視光線透過部を有し、紫外線ランプと紫外線遮蔽樹脂部材との間に、紫外線放射部の周囲の空気が移動可能な空気路68を設ける。その空気路を移動する空気に紫外線を照射することにより、空気中の細菌やウイルス等を殺菌若しくは滅菌すると共に、紫外線不透過・可視光線透過部を透過する可視光線を照明光として用いる。
