Patent number: 6400083Abstract: An electric lamp is provided with an end having an annular recess which contains an insulating member which is secured to the lamp by means of at least two conductors which each extend from the lamp through an aperture in the insulating member. The insulating member and the annular recess are so shaped that the insulating member is held against rotation and lateral displacement with respect to the lamp. The insulating member has cut-out portions remote from its ends, preferably in a central portion, and most preferably configured to have two substantially octagonal portions connected by a portion in the shape of a rectangle, through which cut-out portions underlying material of the annular recess is exposed.Type: GrantFiled: June 10, 1999Date of Patent: June 4, 2002Inventors: Peter Keim, Robert Minderhout, Jacobus C. Peuchen, Harish F. Gandhi

Patent number: 6346767Abstract: A lamp has an electrically insulating, light-transmitting, preferably lead-free envelope with a base end and contains a light source. At least two electrical lead-ins are connected to the light source and exit the envelope. A base is affixed to the base end, the base having first and second electrically conductive portions separated by an electrically insulating portion. One of the electrical lead-ins is electrically connected to the first electrically conductive portion and another of the electrically conductive lead-ins is electrically connected to the second electrically conductive portion. The base is non-rotationally mounted to the base end of the lamp by a locking clip affixed to the first electrically conductive portion by mechanical means and affixed to the base by chemical means.Type: GrantFiled: December 8, 1999Date of Patent: February 12, 2002Assignee: Osram Sylvania Inc.Inventors: Joseph C. Swadel, Howard D. Taggart

Patent number: 6297585Abstract: A fluorescent lamp includes an end cap 4 and a fluorescent tube 1 that has electrode seals 22 and 23 at its ends. The end cap 4 is made of synthetic resin and is attached to the fluorescent tube 1 by silicon resin 31. The end cap 4 includes round cavities 26 and 27 for holding the electrode seals 22 and 23 and thermal protection element holders 20 and 21 for holding thermal protection elements 16 and 17 adjacent to the electrode seals 22 and 23. Pillars 28 are provided between the thermal protection element holders 20 and 21 and the round cavities 26 and 27 to support the thermal protection elements 16 and 17. Through holes 29 are provided between the round cavities 26 and 27 and pillars 28.Type: GrantFiled: July 1, 1999Date of Patent: October 2, 2001Assignee: Matushita Electric Industrial Co., Ltd.Inventors: Yoji Tashiro, Kenji Itaya

Patent number: 6280061Abstract: A halogen lamp with reflector which allows a pinch seal portion to be fitted onto a lamp mount portion of a reflector simply by inserting a lamp body with a pinch seal support and a lead rod support into the lamp mount portion, thrashes the cost and prevents an inorganic adhesive from contaminating a concave reflecting section of the reflector, and is suitable for achieving high wattage. An insulating lead rod support (5) is mounted to lead rods (1b), and a pinch seal support (4) is mounted to the pinch seal portion (1a). The lead rod support (5) is inserted into a bottom aperture (3b) of the lamp mount portion (3). The pinch seal support (4) includes an insertion hole (4d) for passing the pinch seal portion (1b) therethrough, pinch seal abutting pieces (4b), reflector abutting pieces (4a), and an opening closing portion (4c) closing the front opening (6). An adhesive (8) is injected into a gap between the pinch seal portion (1b) and the lamp mount portion (3).Type: GrantFiled: November 18, 1999Date of Patent: August 28, 2001Assignee: Phoenix Electric Co., Ltd.Inventor: Haruo Kokado

Patent number: 6203392Abstract: This invention consists of an improved design and assembly process the for manufacture of a single ended quartz (SEQ) lamp having three-part leads and a prefocus base for projection applications. This invention consists of a much simpler two-pin prefocus ceramic base SEQ lamp design that is made with fewer parts and is much easier and faster to assemble to enable much reduced labor and cost. Also, the ceramic base is smaller and exposes more of the quartz lamp seal to the surroundings to enable more effective cooling during lamp operation to prevent lamp failures from overheated seals. Also, the ceramic base is designed for quick assembly with the coil correctly focused to the base.Type: GrantFiled: December 10, 1999Date of Patent: March 20, 2001Assignee: General Electric CompanyInventors: Bernard W. Rachel, Donald E. Hatfield
