Abstract
An irradiating apparatus includes a support member and a reflector supported by the support member to define a concave light energy reflector surface. A light source of radiating energy is disposed generally at the source focal point of the reflector. The support member has a passage for cooling air to flow therethrough and openings for distributing the cooling air to the apparatus. The support member, thereby, performs a dual function of supporting the reflector as well as providing a manifold for the cooling air.
Claims25
An apparatus for curing a curable coating on an object, comprising:
- an elongated support;
- a plurality of ribs supported by the elongated support and spaced longitudinally therealong, the ribs having concave contour surfaces;
- a thin elongated, sheet-like reflector independent of the elongated support disposed against the concave contour surfaces of said ribs to define an open-sided light energy reflector surface;
- an elongated light source of radiating curing energy generally at the source focal point of the elongated reflector for curing said coating on the object;
- and
- said elongated support having passage means for cooling air to flow therethrough, the passage means having opening means for distributing the cooling air along the apparatus, said passage means being defined entirely by the elongated support independently of the elongated reflector;
- whereby said elongated support performs a dual function of supporting said ribs as well as providing a manifold for said cooling air.
