Patent number: 8215002Abstract: Traditional methods of making headlamp coils have left a portion of the coils with slightly irregular forms. These irregularities can result in defects in the ultimate beam pattern. Accommodating these defects in robust lamp and headlamp optical systems can reduce the performance that might otherwise be available. The preferred coil is therefore continuously coiled as a straight body, and carefully cut into segments. Subsequently, legs are welded to the coil segment ends. The coil is then left substantially undistorted by the manufacturing process that would otherwise normally leave a portion of the coils distorted. The method particularly enables a functional center leg coil.Type: GrantFiled: September 29, 2007Date of Patent: July 10, 2012Assignee: OSRAM SYLVANIA Inc.Inventors: Michael D. Tucker, Charles M. Coushaine, Daniel D. Devir, Paul Okerholm, Douglas Bottom, Stuart K. Denham

Patent number: 7722210Abstract: An advanced forward lighting system may be made with a lamp having a first filament and a second filament extending perpendicular to the first filament. The second filament is partially hidden rearward and above the first filament. A reflector forms a main beam from the first filament light and a right or left cast supplemental beam from the second filament light. The second filament's position minimizes glare, and enables a simple advanced forward lighting system from a single standard lamp fitting both right and left side reflectors.Type: GrantFiled: July 2, 2008Date of Patent: May 25, 2010Assignee: OSRAM SYLVANIA Inc.Inventors: Thomas Tessnow, Joseph C.

Patent number: 5747920Abstract: A lamp capsule with lug connectors, having a lamp bulb, a holder, and a lug is disclosed. The lamp capsule lead extends through the holder passage to fit closely with the lug foot. The lug foot is then rotary swaged to the lamp lead. The swaging mechanically and electrically seals the lead and the lug. An interference coupling is exactly formed along the lead by the swaging, so the lead and lug are precisely located and cannot move with reference to one another. The lug and lead are then tightly held and located with reference to the holder. The mechanical interference fit also forms an electrical connection that cannot separate like a cold weld. The swaging may additionally remove any excess exterior extension of the lead. As a result, the lug is quickly, accurately, and permanently coupled to the lamp lead, and holder preventing subsequent loosening or displacement that may effect lamp positioning or connection durability.Type: GrantFiled: September 26, 1996Date of Patent: May 5, 1998Assignee: Osram Sylvania Inc.Inventors: Daniel D. Devir, Charles M. Coushaine

Patent number: 5711596Abstract: A mechanical electrical connector for an electric lamp lead is disclosed. The connector is formed as a single piece from sheet metal and includes an electrical contact against which the lamp lead is pinched by an approximately perpendicularly extending clamp arm. The clamp arm may be further latched to lock the lead hard against the connector. The single piece connector yields an inexpensive, quickly attached, strong, and permanent mechanical support providing a secure electrical connection for an electric lamp lead.Type: GrantFiled: August 28, 1995Date of Patent: January 27, 1998Assignee: Osram Sylvania Inc.Inventors: John B.

Patent number: 5041955Abstract: A lamp base having an vibration adjustable support structure is disclosed. By supporting a bulb on a plastic clip having arms with fixed lengths, the rotational and axial location of the lamp may be fixed within a standard optical structure, such as reflector housing and lens system. The arms may then be oriented either radially, angularly, or as to thickness or width to control vibration transmission particular to a typical use. For example, standard bulbs, bases and reflector housings may be used with bulb holders variably tuned to accommodate the vibrations specific to particular vehicle models.Type: GrantFiled: November 20, 1989Date of Patent: August 20, 1991Assignee: GTE Products CorporationInventors: Daniel D. Devir, James P. Szep

Patent number: 5029057Abstract: A lamp base having a clipped together support structure is disclosed. Assembly and orientation of lamps is facilitated by a bulb that first clip couples to a bulb and the bulb holder is in turn clip coupled to a lamp base. Electrical connection is made through a duct traversing the bulb holder. By further enabling the bulb holder to lamp base coupling to be rotatable, the lamp pieces may be assembled in secure relation to each other in one operation, and quickly oriented in a second operation. An appropriate bond may be subsequently applied between the bulb holder and the lamp base to permanently fix the two pieces.Type: GrantFiled: November 20, 1989Date of Patent: July 2, 1991Assignee: GTE Products CorporationInventors: Daniel D. Devir, James P. Szep

Patent number: 4979082Abstract: A relieved plastic lamp base has been discovered to substantially eliminated cracking of the captured press seal. The relieved base has a formed cavity for receiving the press seal of an electric lamp. The cavity has a first internal base wall to couple with a first exterior lamp wall of the lamp, a second internal base wall to couple with a second exterior lamp wall of the lamp and, cavity portion formed in the internal base wall intermediate the first interior wall and second interior wall of the lamp. The relief cavity is opposite a seam area of the press seal when the press seal is positioned in the lamp base. The relief accommodates excess material due to tool variations, tool wear, and press variations and thereby allows longer tool operation between tooling changes. The relief also accepts a wider variation in noncritical seal measurements. The relief lessens the likelihood of chipping the seal corner, and displaces the holding forces that tend to open a corner chip.Type: GrantFiled: June 2, 1989Date of Patent: December 18, 1990Assignee: GTE Products CorporationInventor: Daniel D.

Patent number: 4877992Abstract: An electric lamp including an insulative (e.g., plastic) base, an envelope located within the base and having a filament therein and a pair of conductors (e.g., nickel-iron alloy wires) projecting externally from the envelope, passing through the base and extending therefrom. Each conductor includes means (e.g., knurls) formed therein for removing undesirable surface material (e.g., oxide) from a respective contact located within a socket in which the lamp is positioned. Such removal, achieved during lamp insertion and eventual withdrawal, thus assures a sound electrical connection between the "cleaned" contact and a second lamp designed to replace the original. These features are particularly advantageous in the automotive field, especially that portion of the field involving taillight and similar assemblies.Type: GrantFiled: July 9, 1987Date of Patent: October 31, 1989Assignee: GTE Products CorporationInventor: Daniel D.
