A zoomable luminaire has a source of light, a primary reflector with entry and exit apertures, and at least one secondary reflector with entry and exit apertures. The source delivers light into the entry aperture of the primary reflector, and the primary reflector delivers the light at the exit aperture of the primary reflector. The luminaire has a retracted position for producing a beam of a first beam angle, where the primary reflector is nested within the secondary reflector and the secondary reflector does not substantially affect the distribution of the light. The luminaire has at least one extended position for producing a beam of a second width, where the exit aperture of the primary reflector is contiguous with the entry aperture of a secondary reflector so that the light is delivered at the exit aperture of a secondary reflector.
A zoomable luminaire comprising:
A zoomable luminaire comprising a light emitting hemisphere, a conical lower reflector with lower and upper apertures, a conical upper reflector with lower and upper apertures, and a positive lens with a lower and upper surface, said hemisphere positioned into said lower aperture of said lower reflector, said bottom surface of said lens in contact with said upper aperture of said upper reflector, said luminaire with a position of extension for producing a narrow beam and a position of retraction for producing a wide beam, said position of extension comprising the contiguity of said upper aperture of said lower reflector and said lower aperture of said upper reflector, said position of retraction comprising the contiguity of said upper aperture of said lower reflector with said lower surface of said lens, said position of retraction also comprising the nesting of said lower reflector within said upper reflector.
