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

- 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 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.

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).

II. Darstellung der ErfindungII. Presentation of the invention
Es ist die Aufgabe der Erfindung, eine Schcinwerferlampc bereitzustellen, bei der die obengenannten Nachteile vermieden werden.It is the object of the invention to provide a headlight lamp in which the above-mentioned disadvantages are avoided.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Besonders vorteilhafte Ausführungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.
Die erfindungsgemäße Scheinwerferlampe weist mindestens ein Lampengefäß mit mindestens einem darin eingeschlossenen Leuchtmittel und einen Lampensockel auf, der mit den elektrischen Anschlüssen der Scheinwerferlampe versehen ist, wobei der Lampensockel einen ringförmigen metallischen Halter, in dem das mindestens eine Lampengefäß fixiert ist, und mindestens drei in einer gemeinsamen Ebene angeordnete Referenznasen sowie einen ringförmigen Sockelflansch aufweist, dessen So- ckelflanschebene parallel zur Ebene der Referenznasen angeordnet ist, wobei der Sockelflansch mit mindestens drei entlang seines Umfangs angeordneten Laschen versehen ist, die federnd ausgebildet sind und zusammen mit den Referenznasen zur Befestigung der Lampe in einem Scheinwerfer dienen. Erfindungsgemäß sind die Referenznasen an einen Referenzring angeformt sind, der mit dem ringförmigen metallischen Halter und mit dem Sockelflansch verbunden ist und der eine ebene, parallel zur Sockclflanschebenc angeordnete Ringflächc besitzt, wobei der Außcndurch- messer der Ringflächc größer oder gleich dem Innendurchmesser des Sockclflan- sches und größer oder gleich dem Außendurchmesser des ringförmigen metallischen Halters ist, und wobei der Innendurchmesser der Ringflächc kleiner als der Innendurchmesser des Sockclflanschcs und kleiner als der Außcndurchmcsscr des ringförmigen metallischen Halters ist.This object is achieved by the features of claim 1. Particularly advantageous embodiments of the invention are described in the dependent claims. 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. According to the invention, 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.
Durch die vorgenannten Maßnahmen bzw. Merkmale ist gewährleistet, dass zwi- sehen dem Sockelflansch und dem Halter bei der Sockelmontagc keine unerwünschten Schlitze oder Öffnungen entstehen. Der Innen- und der Außendurchmcsser der Ringflächc des zusätzlichen Referenzringes sind so auf die entsprechenden Durchmesser des Sockclflanschcs und des Halters abgestimmt, dass selbst durch die Justa- ge der Leuchtmittcl bezüglich der Referenznasen sich keine Schütze oder Öffnungen zwischen dem Sockelflansch und dem Halter bilden können. Die Ringfläche des Referenzringes kann ferner zur Verschweißung der metallischen Sockelteile, insbesondere des Halters und des Sockelflanschcs verwendet werden. Dadurch bleiben beide Oberflächen der Referenznasen frei von Schweißverbindungen, so dass sie für die Montage der Lampe im Scheinwerfer nutzbar sind. Insbesondere kann die erfin- dungsgemäße Schcinwerferlampc auf zwei unterschiedliche Arten in der als Lampenfassung ausgebildeten Öffnung eines Scheinwerferreflektors montiert werden.
Erstens kann die erfindungsgemäße Lampe so in den Reflektor eingesetzt werden, dass der Rand der Reflektoröffnung mit Klemmsitz zwischen den Referenznasen und den federnd ausgebildeten Laschen des Sockelflansches angeordnet ist. In diesem Fall greifen die Referenznasen in den Reflektor ein und ihre dem Lampengefäß zu- gewandte Oberfläche dient als Referenzebene für die Ausrichtung der Glühwendel bzw. des Leuchtmittels der Lampe innerhalb des Reflektors. Durch das Verriegeln des Bajonettverschlusses, der von den Referenznasen und den Sockelflanschlaschen der Lampe und dem als Lampenfassung ausgebildeten Reflektorrand gebildet wird, gelangen die Referenznasen in ihre vorbestimmte Position im Reflektor, wodurch das Leuchtmittel der Lampe bezüglich des Brennpunktes und der optischen Achse des Reflektors ausgerichtet wird. Zweitens kann die erfindungsgemäße Lampe aber auch so in den Scheinwerfer eingesetzt werden, dass die dem Lampengefäß zugewandte Oberfläche der Referenznasen an der Außenwand des Reflektorrandes anliegt. In diesem Fall muß die Lampe mittels eines Bügels mit Klemmwirkung an der Rück- wand des Reflektors fixiert werden, wie das bei den H4- und H7-Lampcn üblich ist. Die Art der Montage hängt von den Eigenschaften des Scheinwerfers ab.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. In particular, 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. First, 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. In this case, 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. 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.
Der ringförmige metallische Halter ist vorteilhafterweise mit einer Krempe versehen, die auf der Ringfläche des Referenzringes aufliegt und mit ihr verbunden ist. Dadurch wird das Verschweißen des Halters mit dem Referenzring erleichtert. Die Re- ferenznasen sind vorteiihafterweise im Bereich ihrer radial bezüglich des Referenzrings verlaufenden Kanten gewölbt ausgebildet. Dadurch wird vermieden, dass etwaige scharfe Kanten der Referenznasen einen Abrieb an der Reflektorwand verursachen, der zu Schmutzablagerungen im Scheinwerfer führen könnte. Außerdem bilden der Referenzring und der Sockelflansch vorteilhafterweise eine Hinterschnei- dung, um eine Dejustage der Lampe im Scheinwerfer durch einen etwaigen Grat am Reflektorhals zu vermeiden. Zu diesem Zweck ist im Bereich der Kontaktfläche von dem Referenzring und dem Sockelflansch vorteilhafterweise eine ringförmige Nut angeordnet.
III. Beschreibung des bevorzugten AusführungsbeispielsThe 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. In addition, 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. For this purpose, an annular groove is advantageously arranged in the area of the contact surface of the reference ring and the base flange. III. Description of the preferred embodiment

Diese Lampe besitzt ein gläsernes, im wesentlichen zylindrisches Lampengelaß 1 mit zwei darin eingeschlossenen Glüh- wcndcln 2, 3, von denen eine axial und die andere transversal zur Längsachse A der Lampe bzw. zur Zylinderachse des Lampengefäßes 1 angeordnet ist. Die axial angeordnete Glühwcndcl 2 ist teilweise von einer ebenfalls innerhalb des Lampengefäßes 1 angeordneten Abblcndkappe 4 umgeben. Zur Halterung und Spannungsversorgung der Glühwendeln 2, 3 und der Abblendkappe 4 dienen drei Stromzuführungen 5, 6 und 7, die aus dem sockelnahen Ende des Lampengefäßes 1 herausgeführt sind. Das sockelnahc Ende des Lampengefäßes 1 ist mit Klcmmsitz in einer Aussparung eines metallischen Fixierrings 8 verankert, der seinerseits Bestandteil des Lampensockels 9 ist. Der metallische Fixierring 8 ist in dem metallischen Justierring 10 fixiert. Der Justierring 10 weist eine senkrecht zur Längsachse A angeordnete Krempe 10a auf, die mit der ebenen Ringflächc l ld des metalhschen Referenzrings 1 1 verschweißt ist. Der Außendurchmesser des Justierrings 10 beträgt 24 mm und sein Innendurchmesser 19,2 mm. Die Ringfläche l ld des Referenzrings 1 1 ist im wesentlichen senkrecht zur Längsachse A angeordnet. Der Außendurchmesscr des Referenzrings 1 1
bzw. seiner Ringfläche l ld beträgt 28 mm und sein Innendurchmesser 19 mm. Der Referenzring 11 besitzt drei sich im wesentlichen senkrecht zur Längsachse A radial nach außen erstreckende, in einer gemeinsamen Ebene hegende Referenznasen 11a, 11b, 11c. Diese Referenznasen l la-l lc sind an die ebene Ringfläche l ld angeformt und entlang des Umfangs des Referenzringes 11 in einem Abstand von 120 Grad angeordnet. Die Referenznase 11a ist breiter als die beiden anderen Referenznasen 11b, 11c ausgebildet, um eine Orientierung bzw. Einbaulage der Lampe im Scheinwerfer zu definieren. Die beiden Glühwendeln 2, 3 sind mittels der üblichen Justierprozesse beim Verschweißen der Metallsockelteile 8, 10 und 1 1 exakt gegenüber den drei Referenznasen l la-l lc und der durch sie definierten Referenzebene ausgerichtet, so dass beim Einsetzen der Lampe in einen Scheinwerfer durch die Orientierung und Einbaulagc der drei Referenznasen l la- 1 lc innerhalb des Scheinwcrferreflektors auch die Anordnung der Glühwcndcln 2, 3 in dem Reflektor eindeutig fcstlcgbar ist. Der Rcfcrenzring 1 1 ist mit dem ringförmigen Kragen 12d des metallischen, ring- förmigen Sockclflanschcs 12 verschweißt, dessen Flanschcbcne im wesentlichen senkrecht zur Längsachse A angeordnet ist. Der Außcndurchmcsscr des Sockclflanschcs 12 beträgt 39 mm und sein Innendurchmesser 28 mm. Der Sockelflansch 12 besitzt drei gleichmäßig entlang seines Ringumfangs angeordnete, federnd ausgebildete Laschen 12a, 12b, 12c, die eine Federwirkung in Längsrichtung A der Lampe entfalten. Als Gcgcnlager zu den Federlaschcn dienen die Referenznasen l la- l lc. Die Rcfcrcnznasen l la-l lc bilden zusammen mit dem Sockelflansch 12 und seinen Laschen 12a- 12c sowie der entsprechend als Lampenfassung gestalteten Öffnung des Scheinwerferreflektors einen Bajonettverschluß. Der Rand der vorgenannten Öffnung des Scheinwerferreflektors ist nach der Verriegelung des Bajonettverschlusses mit Klemmsitz zwischen den Referenznasen l la-l lc und den Laschen 12a- 12c angeordnet. Zur seitlichen Fixierung der Lampe am Rand des Scheinwerferreflektors dient die Andruckfeder 16, die durch einen Durchbruch in dem ringförmigen Kragen 12d des Sockelflansches 12 nach außen ragt.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. Three power leads 5, 6 and 7, which are led out of the end of the lamp vessel 1 near the base, serve to hold and supply voltage to the incandescent filaments 2, 3 and the dimming cap 4. 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 rcfcrcnznasen l la-l lc together with the base flange 12 and its tabs 12a-12c and the opening of the headlight reflector, which is designed as a lamp holder, form a bayonet catch. 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.
An den metalhschen Sockelflansch 12 schließt sich der Kunststoffring 13 an, der als Spritzgußteil ausgebildet ist, und aus dem drei metallische Kontaktf ahnen 13a, 13b,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,
13c hcrausragen, die jeweils mit einer Stromzuführung 5, 6, 7 elektrisch leitend ver-
bunden sind und die elektrischen Kontakte der Scheinwerferlampe bilden. Das von dem Lampengefäß 1 abgewandte Ende des Lampensockels 9 wird von dem aus Kunststoff bestehenden Griffteil 14 gebildet, das durch eine unlösbare Steckverbindung an dem Kunststoffring 13 und an dem Sockelflansch 12 fixiert ist. Das Griffteil 14 weist einen senkrecht zur Längsachse A, entlang eines Durchmessers des Kunststoffrings 13 verlaufenden Steg 14a auf. Der Steg 14a kann als Griff zum Ver- und Entriegeln des Bajonettverschlusses beim Lampenwechsel dienen.13c protruding, each of which is electrically conductive with a power supply 5, 6, 7 are bound and form the electrical contacts of the headlight lamp. 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.
Die Figuren 3 bis 5 zeigen Details des Sockel flansches 12 und des Referenzringes 1 1. Der Sockelflansch 12 weist drei mit Widerhaken versehene Stege 17 zur Herstel- lung der oben beschriebenen unlösbaren Steckverbindung mit dem Griffteil 14 auf. Die Referenznasen l la-l lc weisen jeweils eine annähernd V-förmige, sich in radialer Richtung des Referenzringes erstreckende Rinne 1 10 auf, die zum Arretieren des oben erwähnten Bajonettverschlusses zwischen der Lampe und dem Scheinwerfer hinter entsprechend darauf abgestimmten Stegen am Reflc torrand dient. Die Refe- renznasen sind im Bereich ihrer radial verlaufenden Kanten 1 1 1 , 1 12 gewölbt, so dass diese Kanten 1 1 1 , 1 12 außerhalb der Ringebene 1 ld verlaufen. Der Kragen 12d des Sockelflansches 12 und der Referenzring 1 1 bilden zusammen - im Bereich ihrer Kontaktfläche - eine Hinterschneidung, so dass ein etwaige Grat am Rand der Reflektoröffnung nicht zu einer Dejustage der Lampe im Scheinwerfer führt, da dieser Grat in der Hinterschneidung verschwinden würde. Durch die Hinterschneidung ist die dem Referenzring 1 1 zugewandte Kante des Kragens 12d des Sockelflansches 12 abgerundet und besitzt einen geringfügig kleineren Außendurchmesser als der restliche Kragen 12d. Dadurch wird im Bereich der Kontaktfläche von dem Referenzring 1 1 und dem Kragen 12d eine ringförmige Nut gebildet (Figur 1 ).
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).
