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.

Mobile ultraviolet radiation curing device

A method is for curing ultraviolet light-curable coatings, inks or adhesives on heat sensitive substrates, wherein the substrates are coated and then passed under ultraviolet light. It includes reducing the temperatures of the substrates while being passed under the ultraviolet light by providing a shield at a location between the ultraviolet light and the substrates. The shield is substantially infrared light reflective and absorptive to prevent infrared light from reaching the substrates and is also substantially ultraviolet light permeable to permit ultraviolet light to reach the substrates. An ultraviolet light curing device utilizing the aforesaid shield is also described for curing ultraviolet light-curable coatings, printings and adhesives on heat sensitive substrates.
