Abstract
A luminaire including a segmented and faceted reflector of two sections describing a concave surface but approximately describing a plurality of paraboloid surfaces of revolution. With simple repositioning of the two reflector sections, a range of reflected beam widths may be achieved. The construction of the reflector sections provides economic fabrication without material reshaping or working and hence dulling of highly reflective material, the fabrication steps including V-notching and bending in two directions.
Claims7
A luminaire adaptable for securing therein a light source through which an optical axis passes, and having an opening through which light from the source is emitted, including a reflector having a plurality of substantially contiguous planar segments, said segments forming a part of a circular arc in a plane behind the source and parallel to the opening to one side of the axis, said arc approximating a parabolic shape with the center of the source at its focus, said reflector parabolically positionable with respect to said source so as to change the reflected beam angle through the opening.
A reflector for a luminaire adaptable for securing therein a light source through which an optical axis passes, and having an opening through which light from the source is emitted, said reflector including:
- a plurality of groups of generally planar facets, said groups each being defined by a plurality of substantially contiguous planar segments, said segments forming parts of circular arcs in planes behind the source parallel with the opening to one side of the axis, said arcs approximating paraolic shape with the center of the source.
