  • the spring legs 22 are used on a Contact surface of a reflector 25 and the lamp holder in a To apply reference position.
  • the spring 20 is on the plastic body Lamp holder 10 fastened by two hot caulked plastic pins 24, the extend through openings in the spring 20.
  • two guide grooves 26 are formed on the plastic body, which encompass the spring legs 22 at a slight distance.
  • the management channels 26 provide mechanical protection for the spring legs, so that these during cannot be bent during transportation of the lamp holder.
  • the illuminant is an H7 incandescent lamp, in which the two contact tabs 30 parallel to each other Extend distance and which has a base plate 31.
  • the plug contacts 28 are attached to the plastic body so that their for connecting cables serving crimp sections perpendicular to the longitudinal axis of the bulb extend.
  • the plug contacts 28 are in the by means of a snap connection Plastic body held.
  • the spring legs 22 on the base plate 31st issue.
  • a positioning lug 36 on the incandescent lamp ensures that this can only be attached to the reflector in a single position.
  • the locking hooks 12 are pressed together, the lamp holder 10 is in the Reflector inserted, and the locking hook 12 are released so that the Latch 14 rests on an associated holding surface 34 on the reflector.
  • the spring legs 22 act on the lamp holder 10 the base plate 31 away from the reflector, so that the lamp holder reliably in a reference position is held.
  • FIGS. 8 to 14 show a lamp holder according to a second one Embodiment shown.
  • components in the second embodiment can be used, which are known from the first embodiment the same reference numerals are used, and reference is made to the above Explanations referenced.
  • the main difference between the first and the second Embodiment is that the lamp holder in the second embodiment is provided for an H1 incandescent lamp, which in FIG. 8 only is indicated.
  • the H1 bulb has a single, centrally located one Contact tab 30, and the second contact is through the base plate 31st realized, which therefore acts as a contact plate.
  • the plug contact 28 is centered in the plastic body of the lamp holder 10 arranged.
  • the second one Embodiment designed the spring 20 for contacting the incandescent lamp, by being provided with a connecting tab 29 on which a cable can be connected.
  • the spring 20 on the underside of the contact plate 31 of the H1 bulb on.
  • the spring legs 22 serve the spring 20 to the lamp holder 10 in a reference position relative to the reflector 25th to act upon.
  • Figure 15 is a lamp holder with reflector according to a third Embodiment shown.
  • the same reference numerals are used, and it in this regard, reference is made to the explanations above.
  • an H1 incandescent lamp is used used.
  • the main difference from the second embodiment is that the cables for contacting the illuminant 32 are not on the lamp holder 10 are connected, but to the reflector.
  • the lamp holder 10 is electrically on each locking hook 12 conductive terminal plate 50 provided on the surface of the locking lug 14th is arranged by means of which the lamp holder is locked on the reflector.
