Definitions

  • the invention relates to a device for fixing a lamp to a reflector neck with an opening for inserting the lamp into the reflector of a vehicle headlamp, wherein the lamp experiences a rotational movement superimposed translational movement transversely to the optical axis of the reflector by turning in the reflector neck.
  • DE 10 2007 022 028 A1 discloses a lighting device for a motor vehicle headlamp, in which a rotation of the lamp during insertion into the reflector neck is converted into a translatory movement of the lamp via a series of adapter parts and in particular by means of a clamping element inserted in these adapter parts , whereby the lamp is brought into engagement with the reflector neck.
  • the structure according to DE 10 2007 022 028 AI is relatively complex and has a variety of items that can be lost when inserting and removing a lamp.
  • a control part is received in a guide formed by the reflector neck and held by a securing member and in the leadership with at least one control surface for converting the rotational movement during insertion of the lamp cooperates in a translational movement transversely to the optical axis of the reflector, so that the securing part with a locking region of the lamp is engageable.
  • the control part is received directly in a guide on the reflector neck and there is displaced during rotation along a control surface, compared to the prior art with significantly fewer parts, namely the control part and the securing part, the Aus GmbH found to an efficient fixing device to realize.
  • the rotation of the lamp during insertion or locking of the lamp in the reflector neck is transmitted to the control part, which slides on rotation on the control surface and according to the geometry of the control surface in a direction transverse to the optical axis of the reflector, ie is moved transversely to the emission direction of the reflector.
  • the term "reflector neck” refers to the end region of the reflector on which the parts of the device according to the invention are fixed.
  • the control part is formed as a ring, with at least one located on the outer circumference of the ring control nose and located on the inner circumference of the ring, can be brought into contact with the lamp driver.
  • the control part is formed substantially annular, the rotational movement of the lamp in the reflector neck is optimally supported during insertion, while the driver can engage for example in a recess in the region of the socket of the lamp.
  • Xenon gas discharge lamps typically have recesses in the region of the socket of the lamp for encoding purposes, i. to uniquely assign a lamp type to a particular reflector.
  • the rotational movement of the lamp is transmitted to the ring and the control nose presses the control member in a direction transverse to the optical axis of the reflector during rotation and thereby takes the lamp with to bring a locking portion of the lamp with the securing part in engagement.
  • the invention is preferably developed in such a way that on the outer circumference of the ring two control ernasen are formed opposite each other, which cooperate with corresponding control surfaces.
  • the two control lugs are thus subject to positive guidance in two opposite displacement directions, so that each angle of rotation of the lamp is associated with a specific position in the direction transverse to the optical axis of the reflector.
  • the lamp When twisting against the direction of rotation, which leads to the insertion of the lamp to lock, therefore, the lamp is moved to a position in which, as before locking, the locking portion of the lamp with the securing part is not engaged, so that the lamp from the reflector neck can be taken out.
  • the determination is, as already explained in detail, by moving the lamp with the control part relative to the securing part, so that the securing part engages behind a certain area of the lamp, which is defined in the context of the present invention as a locking area behind or with this interacts positively. Due to the displacement of the lamp, however, the positive locking takes place only on one side of the lamp.
  • the invention is therefore developed to the effect that the device has a fixed with respect to the reflector neck holding part, which is engageable with the latter during rotation of the lamp.
  • the holding part may protrude, for example, from the reflector neck and be brought into coincidence with the insertion of the lamp, for example, with the above-mentioned recess for the coding.
  • the holding part with a circumferential ring, which is formed between the socket and the starter of the lamp, in engagement and thus provides an additional backup of the lamp at the reflector neck available.
  • the holding part is formed integrally with the securing part.
  • the holding part forms a suitably shaped projection on the securing part, which engages behind the same during rotation of the lamp when inserting.
  • the holding part engages behind the encircling ring, which is formed between the socket and the starter of the lamp.
  • the present invention is used in particular for determining xenon gas discharge lamps.
  • These lamps have in addition to the actual bulbs on the already mentioned starter, which provides a very high initial voltage for ionization of the gas in the piston.
  • Such lamps must be electrically be shielded, as their operation produces strong electromagnetic fields, which may have disturbing influences on the electronics of the vehicle.
  • the device according to the invention is therefore preferably further developed such that the control part is made of an electrically conductive material and is formed for electrical contacting of the lamp. In this way, the EMC shielding of the lamp is carried out by the device according to the invention for its attachment to the reflector, whereby a further integration of the functionalities is achieved.
  • the invention is preferably further developed such that the securing part has at least two projecting beyond the region of the control part projections for screwing the security part on the reflector.
  • the securing part is held by means of a spring element resiliently against the reflector neck.
  • the securing part is held by a spring element, which in turn is held by a cap on the reflector neck or on the reflector, resiliently against the other parts of the device according to the invention, so that a lamp used resiliently in the direction of the reflector is pressed.
  • the spring element is made of an electrically conductive material and formed for electrical contacting of the lamp with the reflector neck.
  • the EMC shield takes place via the spring element, so that the control part can be designed correspondingly simpler.
  • the control part may be made of a material that favors its sliding along the at least one control surface in the guide formed by the reflector neck. For this purpose, in particular material pairings of plastic on the part of the reflector neck and the control surfaces are favorable.
  • the securing part is fixed by means of a spring element at least partially cross-holding element on the reflector neck.
  • the holding element can in this case be screwed to the reflector neck or the reflector, for example, to press the spring element resiliently against the reflector neck.
