The reflector has a proximal end, a distal area, and an intermediate are positioned therebetween. The reflector has an interior surface that includes a first portion that extends from the proximal end to the intermediate area and a second portion that extends from the intermediate area to the distal end. The second portion is less light reflective than the first portion. The lens has two different diffusion rates and includes a center portion having a lens inner diameter and an outer portion surrounding the center portion. The lens inner diameter is about the same diameter as the diameter of the intermediate area. The outer portion is more diffuse than the center portion but allows light to be transmitted therethrough.Type: ApplicationFiled: November 23, 2009Publication date: May 26, 2011Applicant: Cooper Technologies CompanyInventors: Wei Rong, Reed Bradford, Barton Kirk Ideker, Grzegorz Wronski, Adam M.

Publication number: 20110115360Abstract: A light source is combined with an optic and a reflector. Light incident onto to the reflector is reflected with a single reflection. The reflector occupies a portion of a solid angle around the light source to the exclusion of the optic at least with respect to any optical function. The reflector directly receives a second portion of light. The optic occupies substantially all of the remaining portion of the predetermined solid angle to directly receive a first portion of light from the light source. A reflected beam from the reflector is reflected into a predetermined reflection pattern. The inner and/or outer surface of the optic is shaped to refract or direct light which is directly transmitted into the optic from the light source from a first portion of light and/or reflected into the optic from the reflector from the reflected beam into a predetermined beam.Type: ApplicationFiled: November 12, 2010Publication date: May 19, 2011Inventors: Ronald G.

Patent number: 7944133Abstract: Light source device, including an alternating current high-pressure mercury lamp having a pair of opposed electrodes within a spherical light-emitting part containing at least 0.15 mg/mm3 of mercury and 10?6 ?mol/mm3 to 10?2 ?mol/mm3 of halogen, and cylindrical hermetically sealed portions extending from both ends of the light-emitting part. External leads protrude from the ends of the light-emitting part. A reflecting mirror has a concave reflecting part surrounding the light-emitting part and a cylindrical neck part. An adhesive fills a periphery one of the hermetically sealed portions in the area of the external leads in a manner fulfilling the relationship L1/R?0.5 where L1 (mm) is the length along the hermetically sealed portion filled with an adhesive and R (mm) is the diameter of the hermetically sealed portions. Feed wires connect to the external leads and openings for the feed wires can be formed in the reflecting part with flexible tubes between them.Type: GrantFiled: July 16, 2008Date of Patent: May 17, 2011Assignee: Ushiodenki Kabushiki KaishaInventors: Atsushi Imamura, Kenichi Yoshida, Kazuhiro Goto

Patent number: 7923908Abstract: A novel metal halide reflector lamp is described wherein the reflector lamp has a passive optical element to scramble, color mix, and otherwise commingle the light emitted by the metal halide burner. The optical element is placed close to the radiating plasma volume to intercept a large solid angle. Preferably, the optical element substantially intercepts the emitted light within a solid angle that has its vertex at the center of the discharge volume of the burner and is subtended by the open end of the reflector. The optical element can be designed to scatter, reflect or refract the light emanating in this solid angle which otherwise would not impinge on the primary optical control surface of the reflector.Type: GrantFiled: September 27, 2007Date of Patent: April 12, 2011Assignee: Osram Sylvania Inc.Inventor: Walter P.
