Abstract:
1. A device for curing a coating by use of radiant energy comprising: a primary reflector having a cross sectional shape that corresponds to an end portion of a first ellipse, the first ellipse having a major axis and a minor axis and a near focal point and a far focal point, the major axis of the first ellipse bisecting the primary reflector at a first point, the near focal point of the first ellipse being closer to the first point of bisection than is the far focal point of the first ellipse; and a secondary reflector having a cross sectional shape that corresponds to an end portion of a second ellipse, the second ellipse having a major axis and a minor axis and a near focal point and a far focal point, the major axis of the second ellipse bisecting the secondary reflector at a second point, the near focal point of the second ellipse being closer to the second point of bisection than is the far focal point of the second ellipse, the major axis of the first ellipse being longer than the major axis of the second ellipse and the minor axis of the first ellipse being longer than the minor axis of the second ellipse, the primary and secondary reflectors being aligned with one another such that the major axis of the first ellipse is collinear with the major axis of the second ellipse and such that the near focal point of the first ellipse essentially corresponds with the far focal point of the second ellipse and such that the far focal point of the first ellipse essentially corresponds with the near focal point of the second ellipse; and a radiant energy source, the radiant energy source being located such that it substantially overlays the near focal point of the first ellipse and the far focal point of the second ellipse.
