A solid-state light source 10 compatible with existing sockets normally reserved for filamented lamps may be formed with a hollow base 12 formed to mechanically and electrically adapt to a socket. A sub-assembly 14 adapted to cooperate with and fit into the hollow base 12 comprises a metal core 16 h ...

Miguel Galvez, Maria Anc, Richard Speer, William A George: Tubular blue LED lamp with remote phosphor. Osram Sylvania, Robert F Clark, November 17, 2009: US07618157 (127 worldwide citation)

A lamp includes a linearly extending heat sink, blue-light-emitting LEDs mounted on the heat sink, and a light emitting cover mounted on the heat sink in line with the LEDs, a first portion of the cover opposite the LEDs including a phosphor that is excited by the LEDs to emit white light. The cover ...

George J English, Kun Huang, Robert L Garrison: Replaceable LED lamp capsule. Osram Sylvania, William E Meyer, January 27, 2004: US06682211 (118 worldwide citation)

Open LED chips may be arranged directly on the surface of a replaceable lamp capsule without intervening packages that reduce overall light emission. The chips may be oriented in such a way that the lamp generates a unique “donut” shape radiation pattern, which is suitable for a flat and shallow sec ...

Charles M Coushaine: LED light source assembly. Osram Sylvania, William E Meyer, August 22, 2006: US07093958 (108 worldwide citation)

A compact LED light source providing intensive LED positioning along with thermal dissipation can be made with a heat conductive plate supporting a plurality of LEDs mounted on the plate and in thermal contact with the plate. The plate further supports electrical circuitry providing electrical conne ...

Steven C Allen: Remote phosphor LED illumination system. Osram Sylvania, Shaun P Montana, December 27, 2011: US08083364 (94 worldwide citation)

An illuminator is disclosed, in which an LED module emits short-wavelength light toward a phosphor module, which absorbs it and emits wavelength-conditioned light. The emission is generally longitudinal, with a generally Lambertian distribution about the longitudinal direction. The phosphor module i ...

The present invention provides a method for using electrodeless high-intensity discharge (HID) lamps for automotive headlamp and similar applications requiring high/low beam operation (first and second beam orientation) of signaling. The HID lamp is excited with a high-frequency radio frequency (rf) ...

Guang Liu: Low distortion line dimmer and dimming ballast. Osram Sylvania, Carlo S Bessone, May 8, 2001: US06229271 (90 worldwide citation)

A line dimmer has a limited maximum firing angle to limit a total harmonic distortion within a powering signal. A dimming ballast generates a pulse width modulated signal based on a firing angle of the powering signal, generates a dimming command signal based on the pulse width modulated signal, and ...
