Definitions

  • the invention relates to a headlamp according to the preamble of patent claim 1.
  • Such a headlamp is disclosed, for example, in International Patent Application Publication No. WO 97/25733.
  • This document describes a headlamp which has a lamp bulb, an incandescent filament enclosed by the lamp envelope, a lamp cap provided with a base flange and three reference noses arranged in a common plane parallel to the base flange plane, and power supply lines for supplying energy to the incandescent filament.
  • the base flange is equipped with a groove for receiving a sealing ring.
  • the attachment of the lamp in a trained as a lamp holder rear headlight reflector opening is carried out using the reference lugs and resting on the base flange sealing ring.
  • the reference lugs engage in the trained as a lamp holder headlamp reflector opening and the sealing ring abuts against the outer wall of the headlamp reflector.
  • the edge of the reflector opening is therefore arranged by clamping between the sealing ring and the reference lugs.
  • US 4,492,893 describes a cemented halogen incandescent lamp for a headlamp with a positioning ring having a flange-like part.
  • the positioning ring has three, in the radial direction protruding tabs.
  • DE 29 39 328 A1 discloses a headlight for motor vehicles with a cap which is secured axially on the reflector and is pivotable about the reflector neck between an opening and fastening position.
  • the cap has three, in the axial direction acting spring tongues, which hold three, radially projecting from the base flange of the lamp tabs when pivoting the cap in its mounting position to the groove bottom of three grooves in the reflector neck.
  • GB 1 407 024 describes a headlight in which the lamp is fixed by means of a wire bow in the lamp mounting opening of the reflector.
  • US 3,885,149 discloses a lamp with a lamp vessel having a staggered pinch seal.
  • the lamp base has an annular flange with three radially protruding tabs.
  • the headlight lamps according to the invention as claimed are distinguished from the known generic lamps in that the base flange has at least three tabs arranged along the base flange circumference, which are designed to be resilient perpendicular to the bottom plane of the flask. These tabs allow together with the reference lugs attachment of the headlight lamp according to the invention in a lamp mounting opening of the headlamp. The edge of the lamp mounting opening of the headlamp is fixed by clamping the lamp between the reference lugs and tabs according to the invention after insertion of the lamp. A sealing ring and a gas-tight trained plastic base are not required when the headlamp itself is equipped with sealing means for gas-tight closure of the lamp mounting hole.
  • the lugs formed on the base flange are each provided with a protrusion protruding from the plane of the base flange.
  • the base flange and the molded tab advantageously made of a metal. In this way, the easiest way to achieve a spring action perpendicular to the base flange plane and a high strength and elasticity. Since the lamp according to the invention is inserted by a rotational movement into the lamp mounting opening of the headlamp, the tabs integrally formed on the base flange advantageously extend in the azimuthal direction and have the same orientation. In addition, they are preferably formed similar.
  • the preferred embodiment of the invention is a cemented single-cap halogen incandescent lamp intended for use in a motor vehicle headlight.
  • This lamp has a glassy, substantially cylindrical lamp bulb 1, which is fixed in a metallic lamp cap 2.
  • an incandescent filament 3 is arranged, which is connected via two power supply lines 4, 5 to the electrical base contacts 6, 7 is.
  • the lamp cap 2 consists essentially of a cup-like metallic fixing ring 2a, in which one end of the lamp bulb 1 is fixed, a metallic Justierring 2b, in which the fixing ring 2a is fixed, and a metallic reference ring 2c.
  • the lamp base 2 also has a base made of an electrically insulating material 2d, which serves for the electrical insulation of the two base contacts 6, 7.
  • the reference ring 2c is equipped with a substantially rotationally symmetrical base flange 20.
  • the base flanges plane is perpendicular to the ring axis of the reference ring 2c and thus aligned perpendicular to the lamp longitudinal axis.
  • the reference ring 2c is provided with three, at its upper edge formed, radially outwardly directed reference lugs 21 which extend in a common plane parallel to the base flange plane.
  • the adjusting ring 2b has three, integrally formed on its lower edge and radially outwardly angled welding lugs which rest on the reference lugs 21 of the reference ring 2c and are welded to them 21.
  • the base flange 20 is provided with three similar tabs 22 distributed equidistantly along its circumference.
  • the tabs 22 do not extend in the radial, but in the azimuthal direction and their free ends each have a bulge 22a protruding from the plane of the base flange 20. They have the same orientation with respect to the base flange 20 and the ring axis of the reference ring 2c, that is, the base flange 20 and the tabs 22 are formed symmetrically with respect to 120 degree rotations about the ring axis of the reference ring 2c.
  • the tabs 22 are made in one piece with the base flange 20 and consist as well as this 20 of a metal.
  • the tabs 22 exert a spring action perpendicular to the plane of the base flange 20, ie in the direction of the ring axis of the reference ring 2c or in the direction of the lamp longitudinal axis.
  • the reference lugs 21 When mounting the lamp according to the invention in the vehicle headlight, the reference lugs 21 cooperate with the tabs 22.
  • the reference lugs 21 engage in the lamp mounting opening of the headlight and lie on the inside of the headlamp, while the tabs 22 abut the outside of the headlamp.
  • the lamp After inserting the lamp in the lamp mounting hole of the headlamp, the lamp is rotated by a quarter turn about its longitudinal axis fixed in their final position.
  • the edge of the lamp mounting opening is arranged by clamping between the reference lugs 21 and the tabs 22.
  • the reference noses 21 are designed as described in the patent application WO 97/25733.
  • the lamp has a pressure spring which exerts a spring action perpendicular to the longitudinal axis of the lamp and thereby ensures lateral fixing of the lamp in the lamp mounting opening of the headlight.
