Definitions

  • the invention relates to a headlight for vehicles according to the preamble of Claim 1. Furthermore, the invention relates to a method for Manufacture of a headlight according to the preamble of patent claim 10.
  • a headlight for vehicles is known, the one Reflector with an optical axis extending in the horizontal direction, a first focus and a second focus further from the reflector than the first focal point is remote.
  • the first focus of the A light source is arranged in the reflector.
  • the second focal point of the reflector is an aperture arranged to form a light / dark boundary.
  • the aperture is on molded onto a support element which is firmly connected to the reflector.
  • On one A lens is attached to the end of the support element facing away from the reflector has a focus near the second focus of the reflector. The light rays emerging from the headlight are thus after the Projection principle generated.
  • the support element points radially inwards on a side facing the lens protruding approaches on which the lens against the light exit direction is positioned.
  • the peripheral edge of the lens lies within the Support element and is from an inwardly bent edge end of the Support element surrounded to form a gap. There is a in this gap Snap ring can be used so that the lens is held in the opening of the support element is.
  • the disadvantage of the known headlamp is that no tight connection is present between the lens and the support member. Furthermore, due to not optimal process parameters an undesirable, shifted in the axial direction Position of the lens be given, so that an adjustment of the diaphragm is required.
  • DE 92 18 431 U1 is a headlight for vehicles according to one known working principle of projection, in which the lens in Light exit direction is used in a support element and on one inwards shaped edge of the support element comes to rest.
  • the lens are flags of the support element forming an acute angle bent inward towards the light exit direction leading to the edge of the Form lens a gap in which a snap ring can be inserted. This will improved centering and adjustment of the lens.
  • the assembly of the However, lens is relatively complex. A tightness between the lens and the Support element cannot be guaranteed.
  • a headlight for vehicles which according to the Projection principle works and in which a lens by gluing with a Holding element is integrally connected.
  • the holding element is on itself attached to a reflector adjoining support element.
  • the lens is on approaches of the Holding element.
  • the edge surface of the lens lies directly in the radial direction on an inside of the holding element and forms together with inwards angled ends of the holding element an adhesive bed for receiving a Adhesive.
  • a disadvantage of the known headlights is that Tolerance differences in the distributed approaches due to the gluing cannot be compensated.
  • the fact that a lens is provided which is connected to the support element, the headlight has a complex Building on.
  • the object of the present invention is therefore a headlight and a To further develop methods for producing a headlight for vehicles, that a compact design of the headlamp, a safe and reliable Storage of the lens in the same and easy mounting of the headlamp is guaranteed.
  • the invention has the features of claim 1 and the patent claim 10.
  • the advantage of the headlamp according to the invention is in particular that by placing an additional ring the lens captive in a predetermined bonding position can be brought.
  • the axial protruding flange and from this radially protruding circumferential stop is a safe and reliable adjustment of the lens in axial and radial Direction achieved.
  • the formation of the immersion bar causes a higher Dimensional stability of the ring itself.
  • the ring has one from the plunge spaced circumferential retaining web on the surface of the Outside of the flange.
  • the footbridge forms together with the Immersion bridge a first ring channel, which serves to hold the adhesive and thus a guided distribution of the adhesive between the flange and the Ring allows.
  • the holding bridge and the immersion bridge run at a distance from one edge of the flange so that the first ring channel in an area between the stop and one over the Edge of the flange extending transverse plane extends.
  • the ring has an inwardly projecting Nose that covers the circumferential lens edge and together with the Immersion bridge forms a second ring channel for the intake of excess Adhesive. It thus serves on the one hand as an optical cover for the edge of the lens. On the other hand, the inwardly protruding nose enables the lens to be centered.
  • the holding bridge and the nose form one Outside of the ring, so that the ring as a visually appealing decorative ring is trained.
  • the holding web points radially inwards protruding projections on the corresponding receptacles of the flange intervention.
  • the advantage of the method according to the invention is in particular that simple and safe installation is guaranteed.
  • the lens is under System inserted and positioned on a stop of the support element.
  • a final adjustment of the lens is done by placing the ring during the Curing of the adhesive.
  • the ring is under Locking applied with the retaining bridge, so that the lens during the The curing time of the adhesive is captive in the opening of the support element is held.
  • a working on the projection principle headlight (1) consists in essentially of a reflector (2), a light source (3) and a lens (4).
  • the reflector (2) is ellipsoidal and has a central opening that serves as a lamp holder hole for the light source (3).
  • a lamp holder (5) At the back of the Reflector (2) is a lamp holder (5) in one piece with the reflector (2) connected.
  • On the back of the lamp holder (5) is one made of rubber the existing cover cap (6).
  • the light source (3) is designed as an incandescent lamp and with the filament Incandescent lamp (4) in a first focal point of the lens facing away from the lens (4) Positioned reflector (2).
  • the focal point of the reflector (2) is an aperture (7), the edge of which is a Light / dark border generated.
  • the lens (4) is a plane-convex Lens formed in the focal point of the diaphragm (7) is arranged.
  • the screen (7) is formed on a support element (8) which is connected to the reflector (2) is firmly connected.
  • the reflector (2) has an edge Circumferential annular groove (9), in which an approach (10) of the support element (8) engage can and is held in the same by gluing.
  • one Screw connection (11) is provided so that the reflector (2) together with the Carrying element (8) forms a robust housing (23).
  • the headlight (1) can be used as Additional headlights, especially as fog lights, the one below Bumper of a vehicle or arranged in a front end of the vehicle is used.
  • this has Support element (8) on an edge (12) extending in the axial direction annular flange (13) on which is spaced from a free end the same, a stop (14) forming a right angle radially inwards extends.
  • This creates a receptacle for the lens (4) in which it through further measures described below safely and permanently is set.
  • a fork-shaped ring (15) on the edge (12) of the Carrying element (8) set For this purpose, after inserting the lens (4) counter the light exit direction a fork-shaped ring (15) on the edge (12) of the Carrying element (8) set.
  • the ring (15) consists of three essentially opposite to the light exit direction extending annular webs, an outer retaining web (16) approximately has twice the axial extent than that of a central plunge (17).
  • the holding web (16) and the immersion web (17) run essentially parallel to each other.
  • An inner web is designed as a nose (18), which is in one extends acute angle to the immersion web (17).
  • the nose (18) is essential shorter than the immersion web (17) or the holding web (16).
  • the immersion web (17) engages approximately in the center the bead-like protruding adhesive (19) so that the adhesive (19) is pressed flat against the inside of the flange (13).
  • Excess adhesive (19) can in a through the nose (18) and Immersion web (17) formed inner channel (22) escape.
  • the nose (18) comes next to the Decorative function of the ring (15) also a centering function.
  • the lens (4) forms the front end of the light exit direction Headlight (1).
  • the Headlamp (1) has a compact and robust construction.
  • the support element (8) is made of a cast magnesium material.
