US Patent:

44478658, May 8, 1984

Filed:

May 13, 1982

Appl. No.:

6/377754

Inventors:

David D. VanHorn - East Cleveland OH
John M. Putz - Twinsburg OH
Alfred J. Henderson - Shaker Hts. OH

Assignee:

General Electric Company - Schenectady NY

International Classification:

F21V 700

US Classification:

362305

Abstract:

A reflector lamp comprising a concave reflector having a parabolic rear section, a spherical intermediate section, and a faceted parabolic front section, each section having substantially the same common focal point, and a finite light source located at the substantially common focal point. The reflector sections are dimensioned so that substantially all light rays from the finite light source which are reflected by the spherical intermediate section become re-reflected by the faceted parabolic front section. Additionally the light rays, reflected by the facets, include components thereof which are circumferential about a lamp axis and thereby provide a beam pattern which is substantially circumferentially uniform about the lamp axis.
