Patent number: 5495138Abstract: To provide a strain relief in a base for an electric lamp, adapted for coction to an external electrical energy source by at least one connection cable (6a, 6b) extending through and into the base, the base (2) is formed with a strain relief arrangement which includes a resilient sleeve (11) having an inner wall surrounding the at least one connection cable and, within the base bottom portion (9, 9'), a sleeve reception structure (9a) positioned inwardly of the bottom of the base, which includes a sleeve reception bore (10a, 10b) receiving and surrounding the resilient sleeve (11a, 11b) and exerting circumferentially uniformly, radially inwardly directed forces on the resilient sleeve. This decreases the diameter of the sleeve so that the inner wall thereof engages, clamps and squeezes the deformable insulation of the at least one connection cable and, also, can interengage or interlock therewith. The bottom portion (9) and the top portion (7) of the base are snapped together.Type: GrantFiled: September 7, 1994Date of Patent: February 27, 1996Assignee: Patent-Treuhand-Gesellschaft F.

Patent number: 5339002Abstract: To permit rapid adjustment of a holder structure (4) within which a singlnded pinch-sealed light source, for example a halogen incandescent lamp (1, 2) is retained, to a positioning or locating element having an optical reference surface (17a) to accurately align the light emitting element (2) of the light source with respect to an optical system, for example a reflector, a tubular adjustment sleeve (10) is provided into which the holder structure is fitted. The tubular adjustment sleeve has an essentially cylindrical portion (11) and a slightly conically converging portion (12) or an inwardly extending rim or ring (12') to permit rotational, axial and tilting adjustment of the holder structure to which the light source (1) is coupled with respect thereto. The tubular sleeve is formed with a laterally projecting flange (14, 14a) formed with a plane, burr-free engagement surface (14b) which fits against an auxiliary plane, flat reference surface (18b) on the positioning or locating element (15).Type: GrantFiled: December 2, 1991Date of Patent: August 16, 1994Assignee: Patent-Treuhand-Gesellschaft F.

Patent number: 5153480Abstract: To improve shock and vibration resistance and heat dissipation of an attaent element (1) coupling the pinch seal (3) of a halogen incandescent lamp (2) to a plastic base (6), the attachment element is formed of two identical half-sections, surrounding the pinch seal in the shape of a cuff (4) and connected to a flange or skirt by an intermediate heat dissipation and shock absorbing portion (7, 11, 12, 13, 14). Preferably, the intermediate portion forms a connecting section, which can be bent into U or double U configuration off the upper region of the flange or skirt portion (8a, 8b), to provide a large heat radiating surface while retaining the pinch seal of the lamp between undulating sheet-metal portions. Preferably, the attachment element is made of unitary sections of high-quality specialty steel.Type: GrantFiled: July 8, 1991Date of Patent: October 6, 1992Assignee: Patent Treuhand Gesellschaft fur elektrische Gluhlampen mbHInventors: Walter Schoenherr, Alfred Braun, Hermann Steiner

Patent number: 4950942Abstract: To permit ready attachment of a pinch or press seal terminating a halogen incandescent lamp, particularly for automotive use, a base sleeve (9), for example of steel, is formed as a hollow cylinder having, at the end remote from the bulb, at least two spaced flange elements (28) extending radially inwardly of the sleeve and essentially at right angles to the axis of the lamp. A base plug element, formed as a solid body, for example of highly heat-resistant plastic material, is located projecting from the base sleeve, and positioned remote from the bulb. The essentially cylindrical solid body (29) is formed with a circumferential collar of smaller outside diameter, and separated from the remainder of the solid body by a circumferential ring groove.Type: GrantFiled: January 23, 1989Date of Patent: August 21, 1990Assignee: Patent Treuhand Gesellschaft fur elektrische GluhlampenInventors: Alfred Braun, Peter Helbig, Hermann Steiner

Patent number: 4751421Abstract: The bulb (1) of an incandescent lamp, such as a vehicular headlight, is mted on a base structure (3) without cementing, by means of a securing element (2) having two shell-shaped halves (4). Each half (4) has a lug (5) on one side and bent tabs (6) on its other side which engage the lug (5) of the other half (4) to form a cuff around the pinch seal of the lamp and to connect the lamp to the base structure (3), which may be made of plastic. Each half (4) has a flange (8) with a projecting rim (10) whose curvature matches that of a tubular base structure (3). The projecting rim (10) has perforations (9) so that, if a plastic base structure (3) is used, the rim (10) can be connected to the base structure (3) by high-frequency heating, which causes the plastic to permeate the perforations (9) and harden therein.Type: GrantFiled: July 23, 1986Date of Patent: June 14, 1988Assignee: Patent Treuhand Gesellschaft fur elektrische Gluhlampen mbHInventors: Alfred Braun, Walter Schonherr, Hermann Steiner

Patent number: 4595859Abstract: To permit insertion of a lamp-socket combination into a fixture which includes a plate-like portion (P), for example a printed circuit board, a plastic socket (2) is provided which is formed with a recess (6), preferably a through-bore, into which two separating walls (8) extend, which are resiliently outwardly deflectable and have inwardly extending locating ridges (9) which can, after deflection radially outwardly upon insertion of the lamp (1), snap back against the base (4) of the lamp to engage over locating projections (5) formed on the base of the lamp. Terminal strips (7) are inserted in the base at the opposite sides of the separating walls (8), which defines chords of the cylindrical opening (6), the opening providing access for weld-connection of the electrical terminal leads (3) from the lamp to the terminal strips (7).Type: GrantFiled: March 23, 1984Date of Patent: June 17, 1986Assignee: Patent-Treuhand-GesellschaftInventors: Hermann Steiner, Walter Schonherr, Peter Helbig

Patent number: 4412273Abstract: To permit introduction of a halogen incandescent lamp into a reflector, in ealed relationship thereto, a plastic end portion (2c) of the base (2) of the lamp is secured to a metal sleeve, for example of steel, which is telescopically connected to an adjustment cap (2a) in which the bulb (1) is seated. After adjustment of the position of the bulb, so that the filaments will emit light in a predetermined pattern with respect to the base, the adjustment cap and the sleeve are welded together. The plastic portion includes a groove (9) in which a sealing ring (10) for example of silicone rubber is placed, the plastic element including therebeyond a positioning or seating flange (11). The plastic end portion, thus, can readily be assembled with a glass reflector, the sealing ring (10) providing for a moisture tight seal against, for example, a glass reflector.Type: GrantFiled: December 27, 1982Date of Patent: October 25, 1983Assignee: Patent-Treuhand-Gesellschaft fur Elektrische Gluhlampen mbHInventors: Peter Helbig, Walter Schonherr, Hermann Steiner
