More Information
Summary:The object of the present invention is to provide an ultraviolet-emitting device which achieves suppresses deterioration, and prolonged life of the components used in a light-emitting device while monitoring a light emitting state of the light-emitting element and maintaining an emission intensity. The ultraviolet-emitting device (1) is provided with a light-emitting element (131) configured to emit an ultraviolet ray, a mounting board (314) on which the light-emitting element (131) is placed, and a fluorescent glass element (22) placed at a position irradiated with the ultraviolet ray emitted by the light-emitting element (131), and placed in a through hole (314a) formed through the mounting board (314), emitting fluorescence in a visible range by excitation of an ultraviolet ray.
