ULTRAVIOLET RADIATION PRODUCING APPARATUS

摘要

This invention is to prevent reaction products due to ultraviolet radiation from adhering to the window, to prevent reduction of the intensity of the ultraviolet radiation, and to prevent the formation of debris from the reaction products. Presentation of Invention Ultraviolet illumination equipment that has a dielectric-barrier discharge lamp 2 located within a receptacle 1, and a window 3 in the receptacle 1 through which the ultraviolet radiation from the dielectric-barrier discharge lamp 2 is emitted, and that is characterized by establishment of a heating means to heat the window 3 to at least 100 DEG C.
