US 6,207,118 B1 · Mobile ultraviolet radiation curing device

Abstract

A mobile ultraviolet substrate coating curing device which is adapted to cure substrate coatings in inaccessible areas, such as floor corners, walls, overhangs, edges and ceilings includes a curved or generally bent ultraviolet vapor lamp source which is coupled with a power efficient mobile curing unit. The present invention is particularly well adapted to cure any expanse with the unique ability to cure even extraordinarily inaccessible areas. The curved ultraviolet vapor lamp may be shuttered, either manually or automatically. The carriage unit may be operated at constant speed to provide uniform curing energy. The curved ultraviolet vapor lamp is preferably situated adjacent to the coated surface and is preferably backed by a reflector which enhances the curved ultraviolet vapor lamp emissions so as to more adequately broadcast the emissions toward all bordering expanses of the substrate coating. The present invention mobile curing unit may be further adapted to use battery power, thus permitting absolute mobility.
