ABSTRACT:
Ultraviolet curing lamp systems consist of parallel-mounted, elongated ultraviolet lamps which are mounted within elongated reflectors. The reflectors have water-cooling conduits extending along their exterior surfaces, and further have flat, elongated shields extending over the top of the reflector housing. Cooling fluid is introduced into and removed from the cooling channels by coaxial water fittings at opposite corners of the reflector assembly, and the entire reflector assembly and lamp is rotatable about these water inlet and outlet fittings. The parallel assemblies are so disposed that they can illuminate a moving web or sheets of material having radiation curable substances thereon, and are rotatable to a shutter position in which the assemblies are rotated at 90.degree. to their web-illuminating position so that the radiation from each lamp assembly falls on the water-cooled panel on top of an adjacent assembly. The lamp power is also reduced at the time the reflector assemblies are rotated to the rotated position in which ultraviolet energy is removed from the web region.
