ABSTRACT:
In a light source apparatus, a reflector has an inner reflective surface complementary to a part of the outer surface of an ellipsoid with a pair of focal points. The surface part has a first one of the pair of focal points therewithin. An array of light emitting elements is disposed at the position of the first focal point within the reflective surface. Thus, light rays emitted by the array of light emitting elements are reflected by the inner surface of the reflector so as to be focused at the other of the pair of focal points.
