Patent number: 9006981Abstract: End-of-life indicators for lamps, and methods for indicating the end-of-life for lamps, are provided. A solid state light source end-of-life indicator is located on the exterior of a housing of a lamp, and includes at least one light emitting diode. The solid state light source end-of-life indicator emits light at the end of the life of the lamp. The solid state light source end-of-life indicator may emit light upon receiving an end-of-life signal from an end-of-life detection circuit, which detects when the lamp is at an end of its life.Type: GrantFiled: November 12, 2012Date of Patent: April 14, 2015Assignee: OSRAM SYLVANIA Inc.Inventors: Heinz W. Ito, Dan Bodocan, Shaun P. Montana

Patent number: 8264149Abstract: A lamp assembly includes a lamp base having power input terminals, a fluorescent lamp connected to the terminals through a manually operated switch that is on an exterior of the lamp base so that when power is supplied to the terminals the fluorescent lamp is selectively powered by manual operation of the switch, and a light emitting diode (LED) inseparably connected to the terminals so that when power is supplied to the terminals the LED is always powered. This arrangement allows the LED to be ON regardless of the operating status of the fluorescent lamp and allows the fluorescent lamp to be turned OFF while the LED remains ON.Type: GrantFiled: February 23, 2009Date of Patent: September 11, 2012Assignee: Osram Sylvania Inc.Inventors: John M. George, Heinz W. Ito, Robert Y. Pai

Publication number: 20120008324Abstract: A fluorescent lamp is provided that has a plurality of electroded tubes and a plurality of non-electroded tubes. The electroded tubes and the non-electroded tubes each have a proximal end and a distal end. Each proximal end is adjacent a base of the fluorescent lamp. A reflecting mirror is positioned in the proximal end of at least one of the non-electroded tubes or the electroded tubes. The reflecting mirror has a surface reflective of at least some frequencies of visible and ultra-violet light generated by the fluorescent lamp. The electroded tubes can also have a reflecting mirror positioned between the electrode and the end of the tube. In the latter case, an opposite surface of the reflecting mirror can include one or more of an end-of-life composition and/or a runner-up amalgam. A method of placing the reflecting mirror within a tube of a tubular fluorescent lamp is also provided.Type: ApplicationFiled: May 26, 2011Publication date: January 12, 2012Applicant: OSRAM SYLANIA INC.Inventors: Heinz W. Ito, Robert Y. Pai

Publication number: 20110260638Abstract: Reflector-type lamps and housings with integrated heat distribution and EMI shielding are disclosed. A reflector-type lamp includes a lamp housing having a base portion, a reflector portion, and an integrated heat distribution structure. A light source may be located in a reflector housing region or cavity defined by the reflector portion and integrated electronics may be located in a base housing region or cavity defined by the base portion. In general, the heat distribution structure distributes heat from hot spots in the lamp to exterior locations along the base portion and/or reflector portion. The heat distribution structure may also provide electromagnetic interference (EMI) shielding when EMI is generated within the lamp, for example, in the integrated electronics.Type: ApplicationFiled: April 26, 2010Publication date: October 27, 2011Applicant: OSRAM SYLVANIA INC.Inventors: James Gotay, George Mortimer, Heinz W.
