Abstract
An ultraviolet-radiation emitting device comprises a housing having an opening in one side; a reflector positioned in such housing with its reflecting surface facing such opening; and an ultraviolet radiation source disposed in front of such reflecting surface. A glass plate is secured to such one side of the housing and is adapted to filter out relatively short-wave ultraviolet radiation originating from the radiation source, the glass plate covering the opening in such one side of the housing. The edge of the glass plate, except for a portion thereof, is secured to the housing by means of an adhesive layer. An electrical switch operable to switch off the radiation source, such switch including an actuating element bearing against the inner surface of the glass plate and arranged, upon breakage of the glass plate, to operate such switch, is provided. The actuating element is positioned near the edge portion of the plate such that the non-adhered part of the plate is pushed outwards by the actuating element upon breakage of the plate.
