Abstract: An ellipsoidal reflector is provided for a light energy emitting lamp which is used as a heating element within an oven. Because an ellipsoidal reflector is used, the light energy emitting lamp may be positioned at the first focal point of the ellipsoidal reflector in order to concentrate light reflected by the ellipsoidal reflector on the food being cooked. Accordingly, a charbroiled surface effect common to gas or electric cooking grills is produced. The light energy emitting lamp may also be moved away from the first focal point so that light is reflected by the ellipsoidal reflector more uniformly.

The system broadly includes an omnidirectional light source and an elliptical reflector, wherein the physical parameters of the light source and the reflector are matched to produce a narrowly focused beam of intense radiation. The light produced by the system is coupled into a fiber optic system for delivery to the target area.

The aperture is positioned such that only rays meeting predetermined geometrical exit criteria can pass through the aperture and be accepted by the fiber optic located at the second focal point. Those rays which do not meet the exit criteria are reflected by the mirrored surface toward the interior of the cavity.
