Abstract:
1. An optical system of the type having an aperture for light to pass through and designed to collect and project a substantial amount of radiant flux from a quasi point source lamp as a substantially collimated radial beam the optical system comprised of: a. a quasi point source lamp located on an optical axis; b. a segmented radial disk located on said optical axis, said radial disk including parabolic or ellipsoidal radial segments having their focal points coinciding with said quasi point source; each of said radial segments being concave in the transverse section; and c. a segmented reflector ring surrounding the quasi point source being disposed along the optical axis with one set of ring segments disposed to collect reflected beams from the segmented radial disk and another set of ring segments disposed to collect, collimate and direct light from the quasi point source, both sets of reflectors being canted in relationship to the optical axis so that both the reflected beams and refracted direct light are projected in substantially the same radial plane away from the luminaire.
