Definitions

  • the invention relates to an electric lamp according to the preamble of Claim 1.
  • Such an electric lamp is, for example, in the European published application EP 0 786 791.
  • This document describes an electrical Lamp, the base of which is a base sleeve and a welded to it Holding element in which the lamp vessel is anchored. The adjustment of the Illuminant takes place here in two steps, during the attachment of the Lamp vessel in the holding element and during the welding of the Holding element with the base sleeve.
  • the electric lamp according to the invention has a lamp base a lamp vessel anchored in it, which encloses a lamp.
  • the lamp is equipped with an adjustment ring that at least three in a common, perpendicular to the ring axis of the adjusting ring Oriented plane arranged support points and the along its inner surface at least three points of contact with the Has lamp base, the adjusting ring in the at least three points of contact is fixed to the lamp base.
  • the at least three support points of the adjustment ring are in the headlight after the lamp has been installed on a reference plane in the reflector of the headlight. Your arrangement the position of the lamp therefore determines the position of the lamp in the headlight reflector.
  • the orientation of the by the support points defined contact surface with the lamp is indicated by the position of the at least three points of contact that the adjustment ring with the Owns the lamp base.
  • the at least three points of contact of the adjustment ring and the lamp base connected with each other. Since the orientation of the lamp in Headlights only by aligning the adjustment ring with the Lamp base depends, the lamp vessel can already before the adjustment process and be anchored in the lamp base completely independently of this. The aforementioned features of the lamp according to the invention enable therefore a simplified adjustment of the lamp in the headlight.
  • the at least three points of contact are advantageously between the adjustment ring and the lamp base by means of one or more bulges of the lamp base.
  • the most preferred The at least three points of contact are exemplary embodiments of the invention between the adjustment ring and the lamp base using an am Lamp base molded, annular bead produced.
  • the ring-shaped Bead advantageously consists of plastic. As a result, he can be considered to the Lamp base molded part, which also the high voltage resistance of the base are raised.
  • the adjusting ring advantageously consists also made of plastic. To spot weld the adjustment ring and to enable beading using a LASER is advantageously shown in the annular bead at least a first metal part and in the adjusting ring anchored at least a second metal part.
  • the first also owns or for this purpose the second metal part advantageously has a plurality of molded-on parts, spring-loaded welding plumes.
  • the invention is illustrated below with the aid of a preferred exemplary embodiment explained in more detail.
  • the figure shows a cross section through the preferred Embodiment of the invention in a schematic representation.
  • the lamp according to the particularly preferred embodiment of the Invention is a high-pressure discharge lamp with a base on one side with an ignitor integrated in the base, which is used for assembly is provided in a motor vehicle headlight.
  • This lamp owns a lamp base 1 made of plastic, in the interior of which an igniter (not shown) for the high pressure discharge lamp, two glass lamp vessels 2, 3, namely a discharge vessel 2 and one Outer bulb 3, and an adjustment ring made of plastic 4.
  • an igniter for the high pressure discharge lamp
  • two electrodes 5, 6 are arranged, between which a light-emitting gas discharge forms during lamp operation.
  • the outer bulb 3 encloses the discharge vessel 2.
  • the lamp base 1 has an integrally formed annular bead 1a.
  • the ring-shaped Bead 1a surrounds the two lamp vessels 2, 3.
  • the annular Bead 1a is anchored to a first metal ring 7, which forms part of the outer wall of the bead 1a forms.
  • the adjusting ring 4 is one with four molded, resilient second metal ring 8 anchored.
  • the welding lugs 8a protrude in the direction of the ring axis inner surface of the adjusting ring 4 out and are clamped the bead 1a.
  • the welding lugs 8a form four points of contact with the first metal ring 7 of the bead 1a and are in the points of contact spot welded to the first metal ring 7 of the bead 1a.
  • the adjusting ring has three molded support points 4a, which are in a common Layers are arranged and a reference plane for assembly serve the lamp in the headlight reflector.
  • the shape of the metal rings 7, 8 and the welding lugs 8a and the attachment of the lamp vessels 2.3 in Plastic material of the lamp base 1 are in the European publication EP 0 786 791.
  • one of the two Metal rings 7 or 8 are dispensed with and the welding of the bead with the adjusting ring by high frequency induced heating and Melting the plastic material of the bead surrounding the metal ring or the adjustment ring. It is also possible to produce the adjusting ring from a metal instead of plastic and the metallic adjustment ring with molded, resilient welding lugs equip.
