ABSTRACT:
Reflector system includes a reflector having an ellipsoidal portion and a hemispherical portion joined together at the intersection of a plane passing through one of the foci of the ellipsoidal portion normal to the major axis of the ellipsoidal portion. A light source is generally positioned at the focus. The ellipsoidal portion extends forwardly of the focus and terminates in an opening covered by a mirror extending normal to the major axis of the ellipsoidal portion for redirecting light rays emanating from the light source back through the reflector. The center axis of the hemispherical portion intersects the focus, and such hemispherical portion extends rearwardly of the focus and terminates in another opening through which the light rays are redirected by the mirror to a final focus located exteriorly of the reflector.
