Definitions

  • the invention relates to a headlight lamp according to the preamble of patent claim 1.
  • Such a headlight lamp is disclosed, for example, in German published patent application DE 199 51 203 AI.
  • This document describes a headlight lamp with a lamp socket, an incandescent lamp enclosed therein and a lamp base which is provided with the electrical connections of the headlight lamp.
  • the lamp base has an annular, metallic holder for anchoring the lamp vessel.
  • the lamp base has three rcfcrcnnascn arranged in a common plane and a ring-shaped sockclflansch, the sockclflanschcbcnc is arranged parallel to the rcfcrcnznascn plane.
  • the base flange is provided with three resilient flaps arranged along its circumference, which together with the rcfcrcnnnascn serve to fasten the lamp in a headlight. Due to the adjustment of the incandescent lamp with respect to the reference lugs, undesired slots or openings can be created in the lamp socket, so that dust can penetrate into the lamp socket.
  • the headlight lamp according to the invention has at least one lamp vessel with at least one illuminant enclosed therein and a lamp base which is provided with the electrical connections of the headlight lamp, the lamp base having an annular metallic holder in which the at least one lamp vessel is fixed, and at least three in one Common reference lugs arranged and an annular base flange, the base flange level is arranged parallel to the level of the reference lugs, the base flange is provided with at least three straps arranged along its circumference, which are resilient and together with the reference lugs for fastening the lamp in serve a headlight.
  • the reference lugs are formed on a reference ring which is connected to the ring-shaped metallic holder and to the base flange and which has a flat ring surface which is arranged parallel to the base flange, the outer diameter of the ring surface being greater than or equal to the inside diameter of the base flange and is greater than or equal to the outer diameter of the annular metallic holder, and wherein the inner diameter of the annular surface is smaller than the inner diameter of the base flange and smaller than the outer diameter of the annular metallic holder.
  • the aforementioned measures or features ensure that no undesired slots or openings arise between the base flange and the holder during base mounting.
  • the inside and outside diameter of the ring surface of the additional reference ring are matched to the corresponding diameter of the base flange and the holder, so that even the adjustment of the light source with respect to the reference lugs means that no protectors or openings can form between the base flange and the holder.
  • the ring surface of the reference ring can also be used for welding the metallic base parts, in particular the holder and the base flange. As a result, both surfaces of the reference lugs remain free of welded connections, so that they can be used for mounting the lamp in the headlight.
  • the headlight lamp according to the invention can be mounted in two different ways in the opening of a headlight reflector designed as a lamp holder.
  • the lamp according to the invention can be inserted into the reflector in such a way that the edge of the reflector opening with a clamp fit is arranged between the reference lugs and the resilient tabs of the base flange.
  • the reference lugs engage in the reflector and their surface facing the lamp vessel serves as a reference plane for the alignment of the filament or the lamp of the lamp within the reflector.
  • the reference lugs By locking the bayonet catch, which is formed by the reference lugs and the base flange flanges of the lamp and the reflector edge designed as a lamp holder, the reference lugs reach their predetermined position in the reflector, as a result of which the illuminant of the lamp is aligned with respect to the focal point and the optical axis of the reflector , Secondly, however, the lamp according to the invention can also be inserted into the headlight in such a way that the surface of the reference lugs facing the lamp vessel lies against the outer wall of the reflector edge. In this case, the lamp must be fixed to the rear wall of the reflector by means of a clamp with a clamping effect, as is customary with the H4 and H7 lamps. The type of mounting depends on the properties of the headlamp.
  • the ring-shaped metallic holder is advantageously provided with a brim which rests on the ring surface of the reference ring and is connected to it. This makes it easier to weld the holder to the reference ring.
  • the reference lugs are advantageously curved in the region of their edges which run radially with respect to the reference ring. This prevents any sharp edges of the reference lugs from causing abrasion on the reflector wall, which could lead to dirt deposits in the headlights.
  • the reference ring and the base flange advantageously form an undercut in order to avoid misalignment of the lamp in the headlight by any burr on the reflector neck.
  • an annular groove is advantageously arranged in the area of the contact surface of the reference ring and the base flange.
  • Figure 1 is a side view of the preferred embodiment of the headlight lamp according to the invention
  • Figure 2 is a plan view of the headlight lamp shown in Figure 1
  • Figure 3 is a plan view of the base flange of the lamp shown in Figure 1
  • Figure 4 is a top view of the reference ring of the lamp shown in Figure 1
  • FIG. 5 shows a side view of a reference nose of the reference ring shown in FIG. 4
  • the preferred exemplary embodiment of the invention shown in FIG. 1 is a double halogen lamp which is intended for use in a motor vehicle.
  • This lamp has a glass, essentially cylindrical lamp housing 1 with two incandescent filaments 2, 3 enclosed therein, one of which is arranged axially and the other transversely to the longitudinal axis A of the lamp or to the cylinder axis of the lamp vessel 1.
  • the axially arranged glow plug 2 is partially surrounded by a shielding cap 4 which is also arranged inside the lamp vessel 1.
  • the end of the lamp vessel 1 near the base is anchored with a clamp seat in a recess in a metallic fixing ring 8, which in turn is part of the lamp base 9.
  • the metallic fixing ring 8 is fixed in the metallic adjusting ring 10.
  • the adjusting ring 10 has a brim 10a arranged perpendicular to the longitudinal axis A, which is welded to the flat ring surface 11c of the metallic reference ring 11.
  • the outside diameter of the adjusting ring 10 is 24 mm and its inside diameter is 19.2 mm.
  • the ring surface l ld of the reference ring 11 is arranged essentially perpendicular to the longitudinal axis A.
  • the outer diameter of the reference ring 1 1 or its ring surface l ld is 28 mm and its inner diameter 19 mm.
  • the reference ring 11 has three reference lugs 11a, 11b, 11c, which extend essentially radially outward perpendicular to the longitudinal axis A and lie in a common plane. These reference lugs l la-l lc are formed on the flat ring surface l ld and are arranged along the circumference of the reference ring 11 at a distance of 120 degrees.
  • the reference lug 11a is wider than the other two reference lugs 11b, 11c in order to define an orientation or installation position of the lamp in the headlight.
  • the two incandescent filaments 2, 3 are aligned exactly with the three reference lugs l la-l lc and the reference plane defined by them by means of the customary adjustment processes when welding the metal base parts 8, 10 and 11 so that when the lamp is inserted into a headlight by the Orientation and installation position of the three reference lugs l la-1 lc within the headlight reflector and the arrangement of the incandescent lamps 2, 3 in the reflector can also be clearly determined.
  • the locking ring 11 is welded to the annular collar 12d of the metallic, ring-shaped base flange 12, the flange flange of which is arranged essentially perpendicular to the longitudinal axis A.
  • the outer diameter of the base flange 12 is 39 mm and its inner diameter is 28 mm.
  • the base flange 12 has three resiliently designed tabs 12a, 12b, 12c which are arranged uniformly along its ring circumference and which have a spring action in the longitudinal direction A of the lamp.
  • the reference lugs l la l lc serve as bearings for the spring lugs.
  • the edge of the above-mentioned opening of the headlight reflector is arranged between the reference lugs 11a-11c and the tabs 12a-12c after the bayonet catch has been locked with a clamp fit.
  • the pressure spring 16 which projects through an opening in the annular collar 12d of the base flange 12, serves to fix the lamp laterally to the edge of the headlight reflector.
  • the plastic ring 13 which is designed as an injection molded part, and from which three metallic contact tabs 13a, 13b, adjoins the metal base flange 12,
  • the end of the lamp base 9 facing away from the lamp vessel 1 is formed by the plastic handle part 14, which is fixed to the plastic ring 13 and to the base flange 12 by an inseparable plug connection.
  • the grip part 14 has a web 14a running perpendicular to the longitudinal axis A, along a diameter of the plastic ring 13. The web 14a can serve as a handle for locking and unlocking the bayonet lock when changing the lamp.
  • Figures 3 to 5 show details of the base flange 12 and the reference ring 1 1.
  • the base flange 12 has three barbed webs 17 for producing the above-described non-detachable plug connection with the handle part 14.
  • the reference lugs l la-l lc each have an approximately V-shaped groove extending in the radial direction of the reference ring 110, which is used to lock the above-mentioned bayonet catch between the lamp and the headlight behind correspondingly matched webs on the reflective edge.
  • the reference lugs are curved in the region of their radially running edges 11, 1, 12, so that these edges 11, 1, 12 lie outside the ring plane 11d.
  • the collar 12d of the base flange 12 and the reference ring 11 together form an undercut in the area of their contact surface, so that any burr at the edge of the reflector opening does not lead to a misalignment of the lamp in the headlight, since this burr would disappear in the undercut. Due to the undercut, the edge of the collar 12d of the base flange 12 facing the reference ring 11 is rounded and has a slightly smaller outer diameter than the rest of the collar 12d. As a result, an annular groove is formed in the region of the contact surface by the reference ring 11 and the collar 12d (FIG. 1).
