Appl. No.:

10/286727

Inventors:

Thomas Tyler - Wallkill NY, US
Jonathan Connell - Hawley PA, US

International Classification:

F21V007/00

US Classification:

362/297000, 362/347000, 362/346000, 362/348000

Abstract:

A luminaire for providing wide-angle illumination has a housing with an open side and an arcuate reflector with a reflecting surface that defines a plane of substantial symmetry. This reflecting surface is mounted within the housing and arranged to orient the reflecting surface towards the open side and has first and second reflector portions that are substantially mirror images of each other in relation to the plane of symmetry. The reflecting portions define a focal axis that is normal to said plane of symmetry and formed of a plurality of a substantially elongate reflecting facet surfaces or a series of reflector strips each of which is substantially parallel to the focal axis, the arcuate reflector having asymmetrical cycloidal cross sections in planes substantially normal to the focal axis, and the reflector portions forming an indentation or cusp in the direction of the light source at the point where they meet along the plane of symmetry at least in the region of the focal axis. The luminaire additionally has a light source mounted centrally along the focal axis, which provides both a direct light output and a reflected light output through the open side, forming a substantially uniform beam for a predetermined distance in a direction substantially parallel to the plane of symmetry.

Abstract:

Color wheel for lighting fixture, which includes a polygonal metal plate, which has slotted metal bars seated on the side edge of the polygonal plate with rectangular glass plates, e. g. dichroic filters adhesively held in the slots of the metal bars spaced. The glass plates are not in direct contact with the metal bars and are spaced close to each other, but not in contact, in a peripheral array.
