  • This at least one pressure spring ensures a tight fit of the lamp in the lamp holder of the reflector and balances small tolerances in the manufacture of the lamp base and the opening of the headlight reflector designed as a lamp holder out.
  • the at least one pressure spring is as arched Leaf spring executed, the ends of which on the inner wall of the metallic, ring-shaped carrier sleeve.
  • Leaf spring has an outwardly bulging section that is broken through reaches through in the carrier sleeve and after installing the lamp in the reflector lies in the area of the lamp holder on the reflector wall, as well as two inward arched sections, which on either side of the externally curved portion of the leaf spring are arranged.
  • the lamp base is included at least one pressure spring equipped after installing the lamp in the headlight reflector in the area of the lamp holder on the reflector wall is present and a firm seat of the lamp in the lamp holder of the reflector guaranteed.
  • the pressure spring is a curved leaf spring educated. It has an arched outward through a breakthrough reaching through in the carrier sleeve and after installing the Lamp in the headlight reflector on the portion adjacent to the reflector wall, which is provided according to the invention with a V-shaped area. At least the connecting piece connecting the two V-legs engages through the opening in the carrier sleeve, so that after the Installation of the lamp in the headlight reflector on the spring as a lamp holder trained reflector wall.
  • the spring action of the pressure spring compared to that cited above State of the art improved.
  • the angle is the Form two V-legs of the V-shaped area with each other, advantageously chosen so that it is between 80 degrees and 110 degrees.
  • the connecting piece connecting the two V-legs advantageously rounded.
  • the two arched inwards Portions of the leaf spring are advantageously U-shaped.
  • Lamp is a single filament halogen lamp that is for is intended for use in a motor vehicle headlight. That lamp has a glass, essentially cylindrical lamp bulb 50 with a tightly squeezed lamp bulb end 50a that acts as a squeeze foot 50a is referred to.
  • the dome 50b of the lamp bulb 50 is with a black, light-absorbing cover. Serves as a light source a filament 50c aligned parallel to the lamp bulb axis, the electrically conductive with current leads led out of the pinch foot 50a 51 is connected.
  • the lamp bulb 50 is with its pinch foot 50a fixed in a metallic holder part 52 designed as a fixing ring.
  • the Fixring 52 is supported by a metallic intermediate ring 58, which with three molded, angled welding tabs 58a is equipped.
  • the Intermediate ring 58 in turn has a metallic carrier sleeve 53 LASER-welded.
  • the intermediate ring 58 and the metallic support sleeve 53 also has the lamp base plastic socket part provided with the electrical connections 55 of the lamp 54 in which the carrier sleeve 53 is anchored.
  • the electrical connections 55 of the lamp are each welded to one of the power supply lines 51.
  • the plastic base part 54 is an injection molded part, into which the metallic carrier sleeve 53 is injected.
  • the carrier sleeve 53 has three molded, equidistantly along a circumference arranged reference lugs 53a, for adjusting the filament 50c and to fix the lamp in the reflector (not shown) of the Headlights.
  • the reference lugs 53a are from the carrier sleeve 53 angled and lie in a common plane.
  • the welding tabs 58a of the intermediate ring 58 are laser-welded to these reference lugs 53a.
  • the intermediate ring 58 offers additional adjustment options in the reference plane defined by the reference lugs 53a.
  • the plastic base part 54 has an annular, conical design Groove 54b in which a sealing ring (not shown) is made Rubber or silicone is arranged.
  • the sealing ring is on the outside the reflector wall and seals the lamp socket Opening of the reflector.
  • the inside diameter of the sealing ring is matched and varied to fit the conical groove 54b linear with the sealing ring height.
  • the ends 11, 12 of the leaf spring 1 lie on the inner wall of the carrier sleeve 53 and on one each stop 59a, 59b formed in one piece with the plastic base part 54, so that the leaf spring 1 is clamped between these two as a holder executed stops 59a, 59b is fixed.
  • the three reference lugs 53a, the sealing ring arranged in the groove 54b and the pressure spring 1 are used to fix the lamp in the lamp holder of the headlight reflector.
  • the lamp base and the lamp holder form a bayonet catch.
  • the three reference lugs 53a in each case through a cutout in the edge of the opening that fits reach through. Then the lamp in the lamp holder up to turned a stop so that the reflector wall with a clamp fit between the reference lugs 53a and the sealing ring.
  • the pressure spring 1 resiliently lies on the edge of the lamp socket Opening of the reflector.
  • the pressure spring 1 is designed as a curved leaf spring. It has two slightly curved ends 11, 12, which after their assembly on the inner wall the annular support sleeve 53 abut. To fix the leaf spring 1 also serve two made in one piece with the plastic base part 54 Stops 59a, 59b to which the ends 11, 12 abut. The leaf spring 1 is thereby clamped between these stops 59a, 59b (Fig. 10). It has an outwardly curved section 10 with a V-shaped Area 100, which after the assembly of the leaf spring 1 through the opening 53b engages in the carrier sleeve 53 and after the lamp has been installed clamped in the headlight at the reflector opening designed as a lamp holder is applied.
  • the V-legs 101, 102 of the V-shaped area 100 form an angle of approx. 96 degrees with each other and are rounded by a Connector 103 connected together.
  • the breakthrough 53b is shown in the top view in FIG. 2 only with dashed lines, since it is covered by one of the reference lugs 53a.
  • the arched outward Section 10 of the leaf spring 1 is formed by two inwardly curved, U-shaped Sections 13 and 14 each with one of the leaf spring ends 11 or 12 connected.
  • the leaf spring 1 consists of a spring steel sheet with a sheet thickness of 0.25 mm.
  • the reference number 60 in FIG. 2 denotes the Bushings for the power leads 51 of the lamp in the plastic base part 54th
