Publication number: 20140160762Abstract: This disclosure contemplates embodiments of a diffuser element for use with lighting devices that utilize directional light sources, e.g., light-emitting diode (LED) devices. The embodiments utilize a shell wall that forms a volume diffuser with a non-uniform material thickness. The variations in the thickness afford the diffuser with optical characteristics that can improve the distribution of light. In one example, lighting devices that deploy the diffuser element and LED devices distribute light with an optical intensity distribution similar to an incandescent bulb.Type: ApplicationFiled: December 7, 2012Publication date: June 12, 2014Applicant: GE LIGHTING SOLUTIONS, LLCInventors: David C. Dudik, Charles Leigh Huddleston, Benjamin Lee Yoder

The overall shape of the lighting device, particularly the heat sink, can be configured to imitate the appearance of a traditional incandescent candelabra lamp. One or more features are also provided to assist with the conduction of heat away from the LED(s) and to the heat sink. The lighting device can provide improved lumen output and light distribution.Type: ApplicationFiled: September 6, 2012Publication date: March 6, 2014Inventors: Anthony Michael Rotella, Gary Robert Allen, Benjamin Lee Yoder, David C.

Patent number: 8552645Abstract: A ceramic arc body includes a main body having a chamber. A leg extends from the main body and has an internal opening therethrough that communicates with the chamber. An electrically non-conductive seal member is received in the leg opening. A tapered internal surface abuttingly engages the seal member and provides for centering of the seal member relative to the leg. A separate tapering region, shoulder, or stop surface limits insertion of the seal member into the leg opening for precision location of the seal member, and in another embodiment, a single continuous taper inside the leg cooperates with a tapered seal member for both centering and precision insertion of the seal member into the leg. In another embodiment, a hybrid electrode is employed where one portion of the hybrid electrode is electrically non-conductive and a second portion of the electrode is electrically conductive.Type: GrantFiled: October 30, 2009Date of Patent: October 8, 2013Assignee: General Electric CompanyInventors: David C.

Patent number: 8356918Abstract: A light distribution assembly includes an electrodeless HID light source providing emitted light along substantially first and second hemispherical zones. A first optical element redirects a portion of light from the first hemispherical zone into a first desired direction in the second hemispherical zone. A second optical element redirects at least a portion of light within the second hemispherical zone. Other optical elements may be added to tailor the light distribution. Various combinations of these components may be used to create the desired illumination pattern.Type: GrantFiled: October 30, 2009Date of Patent: January 22, 2013Assignee: General Electric CompanyInventors: Gary Robert Allen, Viktor Karoly Varga, David C.

Patent number: 8049425Abstract: A lamp is provided having an arctube having a light-transmitting envelope. The arctube is surrounded by a gaseous medium confined by a containment envelope such as a hermetic shroud. The gaseous medium is preferably He or H2 or Ne or another gas whose thermal conductivity is greater than that of N2 at 800° C., or a mixture thereof, to help cool the arctube. The inside and/or outside of the shroud may be coated with a diffusion barrier. To help cool the hot spot of the arctube the gap between the shroud and the envelope can be made small, the portion of the shroud wall near the arc can be thickened, the arctube can be offset above the longitudinal axis of the shroud, and the return lead of the arctube can be located between the shroud and the arctube.Type: GrantFiled: September 29, 2009Date of Patent: November 1, 2011Assignee: General Electric CompanyInventors: Gary Robert Allen, David C.
