Claims
- 1. An illumination system comprising:
- a light source which emits light;
- a first concave reflective surface or mirror having a center of curvature positioned to collect light from said source at a point remote from said source; a second concave reflective surface or mirror having a center of curvature which collects light from said source within the second half space of emitted light, said second mirror reflects or images said second half space of light to produce a second image of said light source at a point proximate to said light source where said first concave mirror reflects or reimages the light collected from said second concave mirror to provide a third image of said light source at the remote point where said first image is produced; and, a non-imaging reflector having an input aperture positioned to receive substantially all of the light from said first and third images of said light source.
- 2. The illumination system as in claim 1 wherein said second reflecting concave mirror is a spherical reflecting surface.
- 3. The illumination system as in claim 1 wherein a light energy homogenizing element having entrance and exit apertures is placed within its entrance aperture positioned to collect substantially all the light from said first and second concave mirrors, and its exit aperture positioned to direct the collected light to said non-imaging reflector.
- 4. The illumination system as in claim 1 wherein said light source emits light in the infrared wavelength.
- 5. The illumination system as in claim 1 wherein said light source, said centers of curvature of said mirrors and all of said images lie substantially in a common line.
- 6. The illumination system as in claim 1, wherein said non-imaging reflector has a configuration selected from a group consisting of conical, generally aspherical and spline.
