  • the pinch 10 a of the lamp bulb 10 is in a metallic holder, the from the cup-like holder part 14a, the intermediate ring 14e and the annular Carrier sleeve 14b is fixed.
  • the lamp base also provided with the electrical terminals 16, 17 of the lamp Plastic base part 15, in which the annular metallic support sleeve 14b is anchored.
  • the carrier sleeve 14b has three reference lugs lying in one plane 14c and a pressure spring 100 for mounting the lamp in the reflector 20th a motor vehicle headlight.
  • the sealing of the reflector 20 by means of a silicone sealing ring 19, which on the outer wall of the reflector 20 and rests against the plastic base part 15.
  • Figure 1 the structure of the lamp according to of the preferred embodiment and its use in a headlight schematic shown.
  • FIG. 2 shows details of the arrangement of the lamp in the reflector 20 of the motor vehicle headlight.
  • the three reference lugs 14c engage in the fashioned as a lamp socket Mounting opening 21 of the reflector 20 and lie on the inside 20 a of the reflector 20. They are 14c equidistant over the circumference of the annular Carrier sleeve 14b distributed.
  • the pressure spring 100 of the carrier sleeve 14b is below a first reference lug 14 c arranged and is resiliently at the edge 22 of the Lamp mounting opening 21 on.
  • the leaf spring 100 consists of a Spring steel. Their shape is shown in FIGS. 4 and 5.
  • the leaf spring 100 has a V-shaped portion 101 which is between two U-shaped Sections 102, 103 is arranged.
  • the U-shaped sections 102, 103 each connect a leg of the V-shaped portion 101 with a leaf spring 104, 105.
  • Each leaf spring end 104, 105 is provided with two teeth 104a, 105a between each of which the corresponding, from the support sleeve 14b angled flap 14d is arranged ( Figure 3).
  • the teeth 104a, 105a close with the leaf spring ends 104, 105 an angle of 105 degrees.
  • the V-shaped Section 101 engages through a breakthrough in the carrier sleeve 14b and between the two legs of the V-shaped portion 101 arranged, Rounded connection region 101a is at the edge after lamp mounting 22 of the lamp holder designed as a reflector opening 21 resiliently.
  • the leaf spring 100 lies in the transition areas between the V-shaped portion 101 and the U-shaped sections 102, 103 and in the transition areas between the U-shaped sections 102, 103 and the respective leaf spring end 104, 105 on the inner wall of the support sleeve 14b.
  • Reference lugs 14 c the outside of the carrier sleeve 14b each have a recess 14f.
  • Reference lugs 14 c has the edge 22 of the lamp mounting opening 21 of the Reflektors 20 each have a prismatic contact surface 22a.
  • the outside of the carrier sleeve 14b of the lamp cap is located on these two prismatic contact surfaces 22a with a press fit.
  • the clamping action is generated by means of the pressure spring 100.
