ABSTRACT:
An apparatus is provided for curing a curable coating on a three-dimensional object having at least a top surface and a side surface, with the object being advanced along a generally horizontal path. The apparatus includes an elongated light source of radiating curing energy for curing the coating on the surfaces of the object. An open-sided, elongated concave reflector is positioned behind the elongated light source to provide a focus for the radiated curing energy onto the object. The reflector has a generally elliptical cross-section for radiating the curing energy along an energy concentration line generally coincident with the object. The elongated light source is generally at the source focal point of the elongated reflector. The reflector is angled such that a line that runs between the source focal point of the reflector and the energy concentration line extends on the order of 55°-77° from vertical. This angle causes approximately twice as much curing energy and twice the peak intensity to be radiated onto the side surface of the object than onto the top surface of the object.
