Abstract
An optical assembly for architectural illumination which includes a quasi point source surrounded by a collimating ring lens designed to radially project collimated beams. A segmented, off axis, parabolic reflector to collect and reflect light (not gathered by the collimating ring lens) as collimated beams and a ring reflector, the segments of which designed to gather beams from both the collimating ring lens and the off axis reflector and the direct them in substantially the same direction.
Claims15
An optical system designed to collect and project a majority of the radiant flux from a quasi point source lamp as a substantially radial beam, comprising:
- a. a collimating ring lens at least partially surrounding a quasi point light source and segmented so as to project collimated radial beams;
- b. an off axis parabolic reflector of radially collimating segments;
- c. a reflecting ring of individual reflecting elements, some of which relieve and reflect beams projected from the collimating ring lens, some of which relieve and reflect light from sections of the off axis parabolic reflector.
