Reflector system
First Claim
1. A reflector system comprising a reflector having an ellipsoidal portion and a hemispherical portion joined together at an intersection of a plane passing through a focus of said ellipsoidal portion normal to a major axis of said ellipsoidal portion, a hemisphere center of said hemispherical portion coinciding with said focus, a light source generally positioned at said focus, said ellipsoidal portion terminating in an opening forwardly of said focus covered by a mirror extending normal to the major axis of said ellipsoidal portion for redirecting light rays emitted from said light source back through said reflector, and said hemispherical portion terminating in another opening spaced rearwardly from said focus through which the light rays are redirected by said mirror to a final focus located exteriorly of said reflector.

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.

2. A reflector system comprising a reflector having an ellipsoidal portion and a hemispherical portion, said ellipsoidal portion including an ellipsoidal focus within said reflector, said ellipsoidal portion extending forwardly of said focus, and said hemispherical portion extending rearwardly of said focus, and a light source generally positioned at said focus, said ellipsoidal and hemispherical portions being joined together at an intersection of a plane passing through said focus normal to a major axis of said ellipsoidal portion, said ellipsoidal portion terminating in an opening having an axis coinciding with a major axis of said ellipsoidal portion, said opening being covered by a mirror extending normal to said major axis for redirecting light rays emanating from said light source back through said reflector, said mirror including coating means for reflecting substantially all of the visible light generated by said light source and for allowing a major portion of the infra-red radiation generated by said light source to pass through said mirror.
- 3. A reflector system comprising a reflector having an ellipsoidal portion and a hemispherical portion, said ellipsoidal portion including an ellipsoidal focus within said reflector, said ellipsoidal portion extending forwardly of said focus, and said hemispherical portion extending rearwardly of said focus, and a light source generally positioned at said focus, said ellipsoidal and hemispherical portions being joined together at an intersection of a plane passing through said focus normal to a major axis of said ellipsoidal portion, said ellipsoidal portion terminating in an opening having an axis coinciding with a major axis of said ellipsoidal portion, said opening being covered by a mirror extending normal to said major axis for redirecting light rays emanating from said light source back through said reflector, said hemispherical portion terminating in a second opening through which the light rays are redirected by said mirror to the exterior of said reflector, and a target positioned exteriorly of said second opening, said target being located at a final focus for said reflector.
- 8. A reflector comprising an ellipsoidal portion and a hemispherical portion joined together at an intersection of a plane passing through a focus of said ellipsoidal portion normal to a major axis of said ellipsoidal portion, a hemisphere center of said hemispherical portion coinciding with said focus, said ellipsoidal portion terminating in an opening forwardly of said focus covered by a mirror extending normal to the major axis of said ellipsoidal portion for redirecting light rays emitted from a light source positioned at the focus back through said reflector, and said hemispherical portion terminating in another opening spaced rearwardly from said focus through which the light rays are redirected by said mirror exteriorly of said reflector.
- 14. A reflector system comprising a reflector having an ellipsoidal portion and a hemispherical portion, said ellipsoidal portion including an ellipsoidal focus within said reflector, said ellipsoidal portion extending forwardly of said focus, and said hemispherical portion extending rearwardly of said focus, and a light source generally positioned at said focus, said ellipsoidal and hemispherical portions being joined together at an intersection of a plane passing through said focus normal to a major axis of said ellipsoidal portion, said ellipsoidal portion terminating in an opening having an axis coinciding with said major axis, said opening being covered by a mirror extending normal to said major axis for redirecting light rays emanating from said light source back through said reflector, and said hemispherical portion terminating in a second opening through which the light rays are redirected by said mirror to a fixed focus located exteriorly of said reflector.
