Abstract
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.
