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.
