Description

Die Erfindung betrifft eine elektrische Lampe, die aus einem Lampenkolben mit aus dem Kolben herausgeführten Stromzuführungen besteht, aus einem den Lampenkolben fixierenden Halteelement und einer Sockelhülse aus Kunststoff, wobei Halteelement und Sockelhülse mittels Hochfrequenzerwärmen miteinander verbunden sind. Die Lampe weist zudem wenigstens zwei Sockelkontakte auf, die zumindest mit den aus dem Lampenkolben herausge­führten Stromzuführungen elektrisch-leitend verbunden sind.The invention relates to an electric lamp which consists of a lamp bulb with current leads led out of the bulb, a holding element fixing the lamp bulb and a base sleeve made of plastic, the retaining element and base sleeve being connected to one another by means of high-frequency heating. The lamp also has at least two base contacts which are connected in an electrically conductive manner at least to the current leads led out of the lamp bulb.

Eine derartige Lampe, insbesondere für die Verwendung in Kraftfahrzeugscheinwerfern, ist bereits vorgeschla­gen worden (P 35 28 399.8). Diese besteht aus einer Halogenglühlampe, die an ihrer Quetschung von einem Halteelement aus Metall aufgenommen ist. Dieses ist wiederum nach Justierung der Lampe mit der Sockelhülse aus Kunststoff mittels Hochfrequenzerwärmen verbunden.Such a lamp, in particular for use in motor vehicle headlights, has already been proposed (P 35 28 399.8). This consists of a halogen incandescent lamp, which is held in place by a metal holding element. After the lamp has been adjusted, this is connected to the plastic base sleeve by means of high-frequency heating.

Für die erfindungsgemäße Lampe soll jedoch ein Halte­element aus einem elektrisch-isolierenden, hochtempe­raturbeständigen Material zur Anwendung kommen. Der Erfindung liegt deshalb die Aufgabe zugrunde, ein derartiges, den Lampenkolben fixierendes Halteelement zu schaffen, das nach Justierung der Lampe mit der Sockelhülse aus Kunststoff verbunden werden kann.For the lamp according to the invention, however, a holding element made of an electrically insulating, high-temperature resistant material should be used. The invention is therefore based on the object of providing such a holding element which fixes the lamp bulb and which, after adjustment of the lamp, can be connected to the base sleeve made of plastic.

Gelöst wird diese Aufgabe dadurch, daß das den Lampen­ kolben fixierende Halteelement zumindest im Verbin­dungsbereich mit der Sockelhülse aus Kunststoff besteht und in diesem Verbindungsbereich zwischen dem Halteelement und der Sockelhülse ein Mittel aus ferro­magnetischem Material angeordnet ist.This problem is solved in that the lamps piston-fixing holding element consists of plastic at least in the connection area with the base sleeve and a means made of ferromagnetic material is arranged in this connection area between the holding element and the base sleeve.

Um eine Justierung der Lampe gegenüber der Sockel­hülse bzw. einem daran angeformten Einstellring zu ermöglichen, weisen sowohl Sockelhülse als auch das die Lampe fixierende Halteelement im Verbindungs­bereich einen kreisförmigen Querschnitt auf. Da die Lampe nicht nur in ihrer Höhe, sondern auch in ihrer Neigung gegenüber der Sockelhülse justiert werden soll, ist das Halteelement im Verbindungsbereich in vertikaler Richtung konvex gewölbt, so daß Halte­element und Sockelhülse wie ein Kugelgelenk zusammenwirken.In order to enable the lamp to be adjusted relative to the base sleeve or an adjusting ring formed thereon, both the base sleeve and the holding element fixing the lamp have a circular cross section in the connection area. Since the lamp should not only be adjusted in height, but also in its inclination relative to the base sleeve, the holding element in the connection area is convexly curved in the vertical direction, so that the holding element and base sleeve interact like a ball joint.

Das zwischen Halteelement und Sockelhülse angeordnete ferromagnetische Mittel aus beispielsweise einer Nickel-Eisenlegierung kann aus einzelnen zwischenge­klemmten Plättchen bestehen, vorteilhafterweise ist es jedoch als Ring ausgebildet und in einer am Halte­element angeordneten Nut eingelegt. Mittels Hoch­frequenzerwärmung schmilzt der Kunststoff im Bereich des ferromagnetischen Materials, so daß sich Halteelement und Sockelhülse miteinander verbinden.The arranged between holding element and base sleeve ferromagnetic means made of, for example, a nickel-iron alloy can consist of individual sandwiched plates, but advantageously it is designed as a ring and inserted in a groove arranged on the holding element. The plastic melts in the area of the ferromagnetic material by means of high-frequency heating, so that the holding element and base sleeve connect to one another.

Insbesondere bei der Halterung von Hochdruckentla­dungslampen ist es erforderlich, aufgrund der hohen Zündspannung von 15-20 kV und einer Lampenbetriebs­temperatur von ca. 900 °C das den Lampenkolben halternde Teil des Halteelements aus Keramik herzustellen. Eine Möglichkeit, dieses Keramikteil auf dem Kunststoffteil des Halteelements zu befestigen, ist durch eine Ultraschallvernietung gegeben. Man kann diese Teile jedoch auch mittels einer Schnappver­bindung usw. miteinander verbinden.Particularly when holding high-pressure discharge lamps, it is necessary to manufacture the part of the holding element which holds the lamp bulb from ceramic, owing to the high ignition voltage of 15-20 kV and a lamp operating temperature of approximately 900.degree. One way to put this ceramic part on The plastic part of the holding element is attached by ultrasonic riveting. However, these parts can also be connected to one another by means of a snap connection, etc.

Weitere Einzelheiten der Erfindung werden anhand nachfolgender Zeichnungen näher erläutert. Es zeigt

  • Figur 1 ein erstes Ausführungsbeispiel mit einer Halogenglühlampe
  • Figur 2 ein zweites Ausführungsbeispiel mit einer einseitig gequetschten Hochdruckentladungs­lampe
  • Figur 3 ein drittes Ausführungsbeispiel mit einer zweiseitig gequetschten Hochdruckenladungs­lampe
Further details of the invention are explained in more detail with reference to the following drawings. It shows
  • Figure 1 shows a first embodiment with a halogen lamp
  • Figure 2 shows a second embodiment with a high-pressure discharge lamp pinched on one side
  • Figure 3 shows a third embodiment with a bilaterally squeezed high-pressure charge lamp

In Figur 1 ist eine Kraftfahrzeug-Halogenglühlampe dargestellt, die aus einem einseitig gequetschten Lampenkolben 1, darin angeordneten Leuchtkörpern 2 und mit den Leuchtkörpern 2 verbundenen, aus der Quetschung herausgeführten Stromzuführungsdrähten 3 besteht. Der Lampenkolben 1 ist an seiner Quetschung von einem Halteelement 4 aus einem hochtemperatur­beständigen Kunststoff gehalten, das faßförmig, insbesondere einer Kugelschicht entsprechend ausge­bildet ist.FIG. 1 shows a motor vehicle halogen incandescent lamp which consists of a lamp bulb 1 pinched on one side, luminous elements 2 arranged therein and current supply wires 3 connected to the luminous elements 2 and led out of the pinch. The lamp bulb 1 is held at its pinch by a holding element 4 made of a high-temperature-resistant plastic, which is barrel-shaped, in particular a spherical layer.

Des weiteren besteht die Lampe aus einer topfförmigen Sockelhülse 5 und drei auf der dem Lampenkolben 1 abgewandten Seite des Sockelbodens verankerten Sockel­kontakten 6 (nur zwei sind sichtbar). Die Lampenstrom­zuführungen 3 sind durch Öffnungen im Sockelboden hindurchgeführt und auf dessen Rückseite mit den Sockelkontakten 6 verschweißt.Furthermore, the lamp consists of a cup-shaped base sleeve 5 and three base contacts 6 anchored on the side of the base base facing away from the lamp bulb 1 (only two are visible). The lamp power supply lines 3 are through openings in the base base passed and welded to the base contacts 6 on the back.

Zum Schutz der Schweißstelle 7 und zum Abdichten des Sockels ist auf dieser Seite der Sockelhülse 5 ein Abdeckelement 8 aufgesetzt. Dieses ist mit der Sockelhülse 5 ultraschallvernietet und trägt in diesem Ausführungsbeispiel einen Einstellring 9. Der von Sockelboden und Abdeckelement gebildete Zwischenraum 10 ist zusätzlich mit einem Harz aus Kunststoff gefüllt.To protect the welding point 7 and to seal the base, a cover element 8 is placed on this side of the base sleeve 5. This is ultrasonically riveted to the base sleeve 5 and in this exemplary embodiment carries an adjusting ring 9. The intermediate space 10 formed by the base base and cover element is additionally filled with a resin made of plastic.

Wie bereits erwähnt, ist das den Lampenkolben fixierende Halteelement 4 faßförmig ausgebildet und somit gegenüber der zylinderförmigen Sockelhülse 5 und damit auch gegenüber dem Einstellring 9 in seiner Höhe und Neigung frei beweglich. Nach Justierung der Lampe 1 werden Halteelement 4 und Sockelhülse 5, beide aus physikalisch unterschiedlichen Thermoplasten, mit Hilfe eines zwischengelegten ferromagnetischen Ringes 11, der bei Anlegen einer Hochfrequenz das Kunst­stoffmaterial in seiner Umgebung zum Schmelzen bringt, miteinander verbunden.As already mentioned, the holding element 4 which fixes the lamp bulb is of barrel-shaped design and is thus freely movable in its height and inclination with respect to the cylindrical base sleeve 5 and thus also with respect to the adjusting ring 9. After adjusting the lamp 1, the holding element 4 and the base sleeve 5, both made of physically different thermoplastics, are connected to one another with the aid of an interposed ferromagnetic ring 11, which causes the plastic material in its surroundings to melt when a high frequency is applied.

Dieser Ring 11 kann in einer am Halteelement 4 ange­ordneten Nut 12 eingelegt sein. Vorteilhafterweise ist er mit Durchbrüchen 13 versehen, durch die zusätzlich geschmolzenes Kunststoffmaterial zur Erhöhung der Festigkeit der Verbindung hindurchquillen kann.This ring 11 can be inserted in a groove 12 arranged on the holding element 4. It is advantageously provided with openings 13 through which additional molten plastic material can swell to increase the strength of the connection.

Im vorliegenden Ausführungsbeispiel umfaßt der Ring 11 nicht vollständig das Halteelement 4. Dies hat ferti­gungstechnische Vorteile. Der Ring 11 wird von einem Rohr mit kleinerem Durchmesser als der des Halte­ elements 4 abgeschnitten, woraus sich eine Material­einsparung ergibt. Anschließend wird er aufgeschnitten und über das Halteelement 4 geschnappt. Die durch das Aufbiegen des Ringes 11 entstehende Federkraft gibt dem Ring 11 bis nach dem Verbinden von Halteelement 4 und Sockelhülse 5 miteinander einen ausreichenden Halt auf dem Halteelement 4.In the present exemplary embodiment, the ring 11 does not completely include the holding element 4. This has manufacturing advantages. The ring 11 is of a tube with a smaller diameter than that of the holder elements 4 cut off, resulting in a material saving. Then it is cut open and snapped over the holding element 4. The spring force generated by the bending of the ring 11 gives the ring 11 sufficient hold on the holding element 4 until the holding element 4 and the base sleeve 5 have been connected to one another.

Die Figuren 2 und 3 zeigen zwei Ausführungen von Kraftfahrzeug-Entladungslampen. In Figur 2 ist eine einseitig gequetschte Hochdruckentladungslampe 14 mit Sockel dargestellt und in Figur 3 eine zweiendig gequetschte 19.Figures 2 and 3 show two versions of motor vehicle discharge lamps. FIG. 2 shows a high-pressure discharge lamp 14, which is squeezed on one side, with a base, and FIG.

Im folgenden wird nur das beschrieben, was sich von dem Ausführungsbeispiel nach Figur 1 unterscheidet.Only that which differs from the exemplary embodiment according to FIG. 1 is described below.

Die einseitig gequetschte Hochdruckentladungslampe 14 ist in dieser Ausführung von einem zweiteiligen Halteelement 15 getragen. Aufgrund der hohen Zündspannung von 15-20 kV und der hohen Betriebs­temperatur von ca. 900 °C besteht das die Lampe tragende Teil 15a des Halteelements 15 aus Keramik. Dieses ist mit dem Teil des Halteelements aus Kunststoff 15b, das für die Verbindung mit der Sockelhülse 16, ebenfalls aus Kunststoff, vorgesehen ist, mittels Ultraschallnieten verbunden. Für das Kunststoffteil 15b des Halteelements 15 wird ein hochtemperaturbeständiger Thermoplast, wie unter dem Handelsnamen ULTEM 2300 oder RYTO erhältlich, verwendet. Die Sockelhülse 16 besteht beispielsweise aus einem Polyamid.In this embodiment, the high-pressure discharge lamp 14, which is pinched on one side, is carried by a two-part holding element 15. Due to the high ignition voltage of 15-20 kV and the high operating temperature of approx. 900 ° C., the part 15a of the holding element 15 which carries the lamp is made of ceramic. This is connected to the part of the holding element made of plastic 15b, which is provided for connection to the base sleeve 16, also made of plastic, by means of ultrasonic rivets. For the plastic part 15b of the holding element 15, a high temperature-resistant thermoplastic, as available under the trade name ULTEM 2300 or RYTO, is used. The base sleeve 16 consists for example of a polyamide.

In dieser Ausführung weist die Sockelhülse 16 kein eigenes Bodenteil auf. Dieses wird von einem Abdeck­ element 17 übernommen, das auf das untere Ende der Sockelhülse 16 aufgeschnappt ist und durch das die Sockelkontakte hindurchgeführt sind. Der von Halte­element 15, Sockelhülse 16 und Abdeckelement 17 gebildete Hohlraum ist wie in dem zuvor beschriebenen Ausführungsbeispiel mit einem Harz aus Kunststoff gefüllt. Der Einstellring 18 dieser Kraftfahrzeug­entladungslampe ist an der Sockelhülse 16 angeformt.In this embodiment, the base sleeve 16 does not have its own bottom part. This is covered by a cover element 17 taken over, which is snapped onto the lower end of the base sleeve 16 and through which the base contacts are passed. The cavity formed by the holding element 15, base sleeve 16 and cover element 17 is filled with a resin made of plastic, as in the exemplary embodiment described above. The adjusting ring 18 of this motor vehicle discharge lamp is molded onto the base sleeve 16.

Figur 3 zeigt den Lampenaufbau für eine zweiseitig gequetschte Hochdruckentladungslampe 19, der im wesentlichen dem der für die einseitig gequetschte Entladungslampe 14 entspricht. Die Lampe 19 ist ebenfalls von einem aus Keramik bestehenden Teil 20a des Halteelements 20 gehaltert und dieses Keramik­teil 20a ist mit dem aus Kunststoff bestehenden Teil 20b des Halteelements 20 über Ultraschallnietung verbunden.FIG. 3 shows the lamp structure for a high-pressure discharge lamp 19 pinched on both sides, which essentially corresponds to that for the discharge lamp 14 pinched on one side. The lamp 19 is also held by a ceramic part 20a of the holding element 20 and this ceramic part 20a is connected to the plastic part 20b of the holding element 20 by ultrasonic riveting.

Das Keramikteil 20a selbst besteht aus einer runden Platte 20a₁, die auf dem Kunststoffteil 20b des Halteelements 20 aufliegt. Dieser Platte 20a₁ ist ein rinnenförmiges Teil 20a₂ angeformt, das parallel zur Lampe 19 angeordnet ist. Die aus dem Lampenkolben 19 an dem vom Sockel abgewandten Ende herausgeführte Stromzuführung 21 ist mit einem in der Rinne gelagerten Kontakt 22 elektrisch-leitend verbunden, und dieser Kontakt 22 wiederum steht in Verbindung mit einem der Sockelkontakte 23. Die Verbindung 24 zwischen Kontakt 22 und Sockelkontakt 23 ist auf der dem Lampenkolben 19 abgewandten Seite des rinnen­förmigen Teils 20a₂ entlanggeführt.The ceramic part 20a itself consists of a round plate 20a₁, which rests on the plastic part 20b of the holding element 20. This plate 20a₁ is a trough-shaped part 20a₂ formed, which is arranged parallel to the lamp 19. The current lead 21 led out of the lamp bulb 19 at the end facing away from the base is electrically conductively connected to a contact 22 mounted in the groove, and this contact 22 in turn is connected to one of the base contacts 23. The connection 24 between contact 22 and base contact 23 is guided along on the side facing away from the lamp bulb 19 of the channel-shaped part 20a 2.

Das rinnenförmige Teil hat bei dieser Kraftfahrzeug­ lampe nach Figur 3 zusätzlich die Funktion eines Abblendmittels zur Erzeugung der bei Kraftfahr­zeuglampen üblichen Lichtverteilung.The channel-shaped part has in this motor vehicle 3 additionally the function of a dimming means for generating the light distribution customary in motor vehicle lamps.
