Insbesondere darf die Ausdehnung L1 der Lampe in Längserstreckungsrichtung von der senkrecht dazu orientierten Referenzebene des Lampensockels bis zur Lampengefäßkuppe den Wert von 44,0 mm nicht überschreiten. Das heißt, die Bedingung L1 < 44,0 mm muss erfüllt sein. Außerdem muss gemäß der ECE-Regel 37 bei den Halogenglühlampen der Kategorien H7, H8 und H16 eine metallfreie Zone gewährleistet sein, um eine Störung durch Streulicht und Spiegelbilder im Fahrzeugscheinwerfer zu verhindern. Diese metallfreie Zone ist in
Es ist Aufgabe der Erfindung, eine gattungsgemäße Halogenglühlampe für Fahrzeugscheinwerfer bereitzustellen, die eine erhöhte Stabilität gegenüber Vibrationen besitzt.It is an object of the invention to provide a generic halogen incandescent lamp for vehicle headlights, which has an increased stability to vibration.
Diese Aufgabe wird durch eine Halogenglühlampe mit den Merkmalen gemäß dem Patentanspruch 1 gewährleistet. Besonders vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Patentansprüchen beschrieben.This object is ensured by a halogen incandescent lamp having the features according to the
Die erfindungsgemäße Halogenglühlampe besitzt einen Lampensockel, der eine Referenzebene zur Ausrichtung der Halogenglühlampe im Fahrzeugscheinwerfer definiert und der ein Halterteil mit einer im wesentlichen rotationssymmetrischen Außenkontur zur Halterung eines lichtdurchlässigen Lampengefäßes umfasst, wobei das Halterteil einen ersten, mit einem Bauteil des Lampensockels verbundenen Halterteilabschnitt und einen zweiten Halterteilabschnitt besitzt, aus dem das lichtdurchlässige Lampengefäß herausragt. Erfindungsgemäß besitzt der zweite Halterteilabschnitt einen kleineren Außendurchmesser als der erste Halterteilabschnitt und die Höhe des Lampensockels über der Referenzebene liegt erfindungsgemäß im Bereich von 11,5 mm bis 16,6 mm. Letzteres heißt, dass die Höhe des Lampensockelabschnitts, der zwischen der Referenzebene und dem aus dem Lampensockel herausragenden Abschnitt des Lampengefäßes liegt, im Bereich von 11,5 mm bis 16,6 mm liegt.The halogen incandescent lamp according to the invention has a lamp base which defines a reference plane for aligning the halogen incandescent lamp in the vehicle headlight and which comprises a holder part with a substantially rotationally symmetrical outer contour for holding a translucent lamp vessel, the holder part having a first holder section connected to a component of the lamp cap and a second Holder section has, from which protrudes the translucent lamp vessel. According to the invention, the second holder portion has a smaller outer diameter than the first holder portion and the height of the lamp cap above the reference plane is according to the invention in the range of 11.5 mm to 16.6 mm. The latter means that the height of the lamp cap portion, which lies between the reference plane and the portion of the lamp vessel protruding from the lamp cap, is in the range of 11.5 mm to 16.6 mm.
Dadurch kann die erfindungsgemäße Halogenglühlampe mit einem im Vergleich zum Stand der Technik verkürzten Lampengefäß ausgestattet werden und zusätzlich der von der Norm ECE-Regel 37 vorgeschriebene Abstand des mindestens einen Glühfadens zur Referenzebene von 25 mm ± 0,1 mm gewahrt werden. Aufgrund des verkürzten Lampengefäßes, das vorzugsweise mit seiner Lampengefäßabdichtung im Halterteil fixiert ist, wird die Vibrationsbeständigkeit der Lampengefäßhalterung erhöht. Außerdem kann dadurch die erfindungsgemäße Halogenglühlampe verkürzte Stromzuführungen für den mindestens einen Glühfaden besitzen. Das heißt, die innerhalb des Lampengefäßes verlaufenden Abschnitte der Stromzuführungen, die mit dem mindestens einen Glühfaden verbunden sind, können ebenfalls kürzer ausgebildet als bei Halogenglühlampen gemäß dem Stand der Technik. Insbesondere können bei erfindungsgemäßen Halogenglühlampen die innerhalb des Lampengefäßes verlaufenden Abschnitte der Stromzuführungen für den Glühfaden um ca. 30% bis 40% kürzer sein als bei Halogenglühlampen gemäß dem Stand der Technik. Dadurch besitzen die erfindungsgemäßen Halogenglühlampen zusätzlich auch eine Glühfadenhalterung mit erhöhter Vibrationsbeständigkeit. Der kleinere Außendurchmesser des zweiten Halterteilabschnitt des Halterteils für das Lampengefäß gewährleistet, dass die erfindungsgemäßen Halogenglühlampen die bereits weiter oben beschriebene metallfreie Zone gemäß der ECE-Regel 37 besitzen.As a result, the halogen incandescent lamp according to the invention can be equipped with a shortened compared to the prior art lamp vessel and in addition the prescribed by the standard ECE Rule 37 distance of at least one filament to the reference plane of 25 mm ± 0.1 mm are maintained. Due to the shortened lamp vessel, which is preferably fixed with its lamp vessel seal in the holder part, the vibration resistance of the lamp vessel holder is increased. In addition, thereby the halogen incandescent lamp according to the invention shortened power supply for the at least one filament. That is, the portions of the supply leads which are connected within the lamp vessel and which are connected to the at least one filament can also be made shorter than in the case of halogen incandescent lamps according to the prior art. In particular, in the case of halogen incandescent lamps according to the invention, the sections of the supply leads for the filament extending within the lamp vessel can be shorter by approximately 30% to 40% than in the case of halogen incandescent lamps according to the prior art. As a result, the halogen incandescent lamps according to the invention additionally have an incandescent filament holder with increased vibration resistance. The smaller outer diameter of the second holder section of the holder part for the lamp vessel ensures that the halogen incandescent lamps according to the invention have the metal-free zone described above according to ECE rule 37.

Gemäß einem ersten bevorzugten Ausführungsbeispiel der Erfindung sind der erste und der zweite Halterteilabschnitt jeweils zylindrisch ausgebildet, wobei der zweite Halterteilabschnitt, aus dem das Lampengefäß herausragt, einen kleineren Außendurchmesser besitzt als der erste Halterteilabschnitt, der mit einem Bauteil des Lampensockels verbunden ist. Das heißt, das Halterteil besitzt einen entlang seiner Rotationsachse in Richtung der Seite, aus der das Lampengefäß herausragt, stufenartig reduzierten Außendurchmesser. Gemäß einem zweiten bevorzugten Ausführungsbeispiel der Erfindung ist der zweite Halterteilabschnitt, aus dem das Lampengefäß herausragt, kegelstumpfartig und der erste Halterteilabschnitt, der mit einem Bauteil des Lampensockels verbunden ist, zylindrisch ausgebildet. Das heißt, das Halterteil ist entlang seiner Rotationsachse in Richtung der Seite, aus der das Lampengefäß herausragt, konisch verjüngt ausgebildet. Alternativ kann auch der erste Halterteilabschnitt kegelstumpfartig und der zweite Halterteilabschnitt zylindrisch ausgebildet sein. Als weitere Alternative können auch der erste und der zweite Halterteilabschnitt kegelstumpfartig ausgebildet sein.The smaller outer diameter of the second holder portion can be realized in different ways to ensure the aforementioned metal-free zone. According to a first preferred embodiment of the invention, the first and the second holder portion are each formed cylindrical, wherein the second holder portion, from which protrudes the lamp vessel has a smaller outer diameter than the first holder portion portion which is connected to a component of the lamp cap. That is, the holder part has one along its axis of rotation in the direction of the side from which protrudes the lamp vessel, gradually reduced outside diameter. According to a second preferred Embodiment of the invention is the second holder portion portion from which protrudes the lamp vessel, a truncated cone and the first holder portion portion which is connected to a component of the lamp cap, cylindrical. That is, the holder part is tapered along its axis of rotation in the direction of the side from which the lamp vessel protrudes. Alternatively, the first holder portion section may be frustoconical and the second holder portion may be cylindrical. As a further alternative, the first and the second holder portion may be truncated cone-shaped.
Mit anderen Worten formuliert, das Halterteil ist bei allen Varianten der erfindungsgemäßen Halogenglühlampe derart ausgebildet, dass sein Außendurchmesser entlang der Rotationsachse des Halterteils in Richtung der Seite, aus der das Lampengefäß herausragt, stufenartig oder nach Art eines Kegelstumpfes reduziert ist, um die metallfreie Zone gemäß ECE Regel 37 zu gewährleisten. Bei allen vorgenannten Varianten kann das Halterteil der erfindungsgemäßen Halogenglühlampe auf einfache Weise mit einem Bauteil des Lampensockels, insbesondere mit einer zylindrischen Metallhülse, verbunden werden.In other words, the holder part is formed in all variants of the halogen incandescent lamp according to the invention such that its outer diameter along the axis of rotation of the holder part in the direction of the side from which the lamp vessel protrudes, is reduced stepwise or in the manner of a truncated cone to the metal-free zone according to To ensure ECE rule 37.

Vorzugsweise liegt die Höhe des Lampensockels der erfindungsgemäßen Halogenglühlampe im Bereich von 12 mm bis 16,6 mm und besonders bevorzugt im Bereich von 13 mm bis 16 mm über der Referenzebene des Lampensockels. Bei einer größeren Höhe des Lampensockels von mehr als 16,6 mm über der Referenzebene ließe sich auch mit einem konischen Halterteil die Bedingung der metallfreien Zone nicht mehr gewährleisten und bei einer geringeren Höhe des Lampensockels als 11,5 mm über der Referenzebene ließe sich keine nennenswerte Verbesserung der Vibrationsfestigkeit der Halogenglühlampe erreichen.Preferably, the height of the lamp cap of the halogen incandescent lamp according to the invention is in the range of 12 mm to 16.6 mm and particularly preferably in the range of 13 mm to 16 mm above the reference plane of the lamp cap. With a greater height of the lamp cap of more than 16.6 mm above the reference plane, even with a conical holder part, the condition of the metal-free zone would no longer be possible and at a lower height of the lamp cap than 11.5 mm above the reference plane, no appreciable improvement in the vibration resistance of the halogen incandescent lamp could be achieved.
Die Höhe des zweiten Halterteilabschnitts liegt vorzugsweise im Bereich von 3 mm bis 6 mm, um auf möglichst einfache Weise eine Vergrößerung der Höhe des Lampensockels über der Referenzebene zu erreichen und dabei die anderen Komponenten des Lampensockels der erfindungsgemäßen Halogenglühlampe unverändert vom Lampensockel der Halogenglühlampe gemäß dem Stand der Technik übernehmen zu können.The height of the second holder portion is preferably in the range of 3 mm to 6 mm in order to achieve the simplest possible increase in the height of the lamp cap above the reference plane and the other components of the lamp cap of the halogen incandescent lamp according to the invention unchanged from the lamp base of the halogen incandescent lamp according to the state to be able to take over the technology.

Insbesondere benötigen die erfindungsgemäßen Halogenglühlampen aufgrund der geringen Abmessungen ihres Lampengefäßes eine geringere Menge an Edelgas, wie beispielsweise Xenon oder Krypton, so dass sich dadurch auch eine Kosteneinsparung ergibt.This also allows the volume of the lamp vessel and the distance of the filament to the lamp vessel and the amount of filling gas for the halogen cycle to the electrical power consumption of the halogen incandescent lamp according to the invention can be adjusted. In particular, because of the small dimensions of their lamp vessel, the halogen incandescent lamps according to the invention require a smaller amount of noble gas, such as, for example, xenon or krypton, so that this also results in cost savings.
Das Lampengefäß der erfindungsgemäßen Halogenglühlampe besteht vorzugsweise aus Hartglas, beispielsweise aus alkalifreiem Erdalkali-Alumino-Silikatglas. Dadurch werden für die Stromzuführungen keine Molybdänfolieneinschmelzung benötigt und die Stromzuführungen für den mindestens einen Glühfaden können als Drähte unmittelbar durch die Lampengefäßabdichtung gasdicht nach außen hindurchgeführt werden, wodurch wiederum Lampengefäße mit sehr kleinen Abmessungen ermöglicht werden.The lamp vessel of the halogen incandescent lamp according to the invention is preferably made of hard glass, for example alkali-free alkaline earth aluminosilicate glass. As a result, Molybdänfolieneinschmelzung are required for the power supply lines and the power supply lines for the at least one filament can be passed as wires directly through the lamp vessel sealing gas-tight to the outside, which in turn lamp vessels are made possible with very small dimensions.
Bei den erfindungsgemäßen Halogenglühlampen liegt im Fall von Halogenglühlampen der Kategorien H7, H8 und H16 der Abstand des Glühfadens zur Referenzebene im Bereich von 25,0 mm ± 0,1 mm, um die Vorgaben der Norm ECE-Regel 37 für diese Lampenkategorien zu erfüllen.In the halogen incandescent lamps according to the invention in the case of halogen lamps of categories H7, H8 and H16, the distance of the filament to the reference plane in the range of 25.0 mm ± 0.1 mm to meet the requirements of the standard ECE rule 37 for these lamp categories.

In
Diese Halogenglühlampe besitzt ein aus Hartglas, beispielsweise alkalifreiem Erdalakali-Alumino-Silikatglas, bestehendes lichtdurchlässiges Lampengefäß 1, das in dem Metallsockelteil 21 eines Lampensockels 2 fixiert ist. Das sich an das Metallsockelteil 21 anschließende Kunststoffsockelteil 22 des Lampensockels 2 ist mit den elektrischen Anschlüssen 6 der Halogenglühlampe ausgestattet. Das gasdicht verschlossene Lampengefäß 1 besitzt ein abgedichtetes Ende 11, das in einem Halterteil 214 des Metallsockelteils 21 fixiert ist, und einen hohlen, kreiszylindrischen mittleren Lampengefäßabschnitt 12 sowie eine Lampengefäßkuppe 13, die dem abgedichteten Ende 11 gegenüberliegt und mit einer lichtundurchlässigen Beschichtung versehen ist. Der kreiszylindrische Lampengefäßabschnitt 12 besitzt einen Außendurchmesser von 9,5 mm, eine Wandstärke von 0,9 mm und einen Innendurchmesser von 7,7 mm. Die Länge L2 des kreiszylindrischen Lampengefäßabschnitts 12 in Richtung seiner Zylinderachse gemessen, das heißt die Längsausdehnung des Lampengefäßes 1 zwischen dem abgedichteten Ende 11 und der Lampengefäßkuppe 13, beträgt ca. 14,2 mm. Im Innenraum des Lampengefäßes 1 befindet sich eine Füllgasmischung, die Halogene und Edelgas, beispielsweise Krypton oder Xenon, umfasst. Der bei 22 Grad Celsius gemessene Füllgasdruck liegt im Bereich von 1,5 bis 1,8 Megapascal. Innerhalb des Lampengefäßes 1 befindet sich im Bereich des kreiszylindrischen mittleren Lampengefäßabschnitts 12 ein als Wolframwendel ausgebildeter Glühfaden 3. Die Wickelachse A der Wendel 3 ist parallel versetzt zur Zylinderachse des kreiszylindrischen Lampengefäßabschnitts 12 angeordnet. Die beiden Enden 31, 32 der Wendel 3 sind jeweils mit einem Stromzuführungsdraht 4, 5 aus Molybdän verschweißt. Die beiden Stromzuführungsdrähte 4, 5 sind aus dem abgedichteten Ende 11 des Lampengefäßes 1 herausgeführt und jeweils mit einem der beiden elektrischen Anschlüsse 6 der Halogenglühlampe verbunden. Der in den kreiszylindrischen Lampengefäßabschnitt 12 hineinragende Abschnitt des Stromzuführungsdrahtes 4 erstreckt sich bis zu einer Höhe von ca. 10,5 mm über dem abgedichteten Ende 11 des Lampengefäßes und ist damit um 29% kürzer als Halogenglühlampen gemäß dem Stand der Technik. Der in den kreiszylindrischen Lampengefäßabschnitt 12 hineinragende Abschnitt des anderen Stromzuführungsdrahtes 5 erstreckt sich bis zu einer Höhe von ca. 5,2 mm über dem abgedichteten Ende 11 des Lampengefäßes und ist damit um 37% kürzer als Halogenglühlampen gemäß dem Stand der Technik. Die beiden elektrischen Anschlüsse 6 sind als metallische Kontaktfahnen ausgebildet deren erstes Ende jeweils mit dem Stromzuführungsdraht 4 oder 5 verschweißt ist und deren zweites Ende über das steckerartige ausgebildete Kunststoffsockelteil 22 zum Anschließen der Versorgungsspannung der Halogenglühlampe zugänglich ist. Das Verschweißen von Stromzuführungsdrähten 4, 5 und Kontaktfahnen 6 erfolgt mittels Laser über Durchbrüche in der ersten Metallhülse 211, wie es beispielsweise in der
Der Lampensockel 2 besteht aus einem als Kunststoffspritzgussteil ausgebildeten Kunststoffsockelteil 22, in dem die elektrischen Anschlüsse 6 der Halogenglühlampe eingebettet sind, und einem Metallsockelteil 21, das aus mehreren metallischen Komponenten 211, 212, 213, 214 zusammengesetzt ist.The
Das Kunststoffsockelteil 22 besitzt eine Oberfläche 220, aus der eine erste, hohlzylindrische Metallhülse 211 herausragt. Diese erste hohlzylindrische Metallhülse 211 ist mittels Spritzgusstechnik oder mittels Hochfrequenz-Einschmelztechnik mit dem Kunststoffsockelteil 22 verbunden und bildet eine Komponente des Metallsockelteils 21. Die Mantelfläche der ersten hohlzylindrischen Metallhülse 211 weist einen Durchbruch auf, durch den eine Andruckfeder 215 hindurchragt, die in radialer Richtung der ersten Metallhülse 211 eine Federwirkung besitzt. Auf der vorgenannten Oberfläche 220 des Kunststoffsockelteils 22 liegt ein Dichtungsring 23 aus Silikon auf, der koaxial zur ersten, hohlzylindrischen Metallhülse 211 angeordnet ist. Der Dichtungsring 23 ist geringfügig konisch geformt, das heißt sein Innendurchmesser und sein Außendurchmesser nehmen von seiner auf der Oberfläche 220 aufliegenden Unterseite in Richtung seiner den Referenzlaschen 213a zugewandten Oberseite zu. Dadurch ist der Dichtungsring 23 mit Klemmsitz in einer passgerecht von dem Kunststoffsockelteil 22 geformten Nut fixiert. Das Metallsockelteil 21 besitzt außerdem eine zweite hohlzylindrische Metallhülse 212, die an ihrer, der ersten Metallhülse 211 zugewandten Unterkante einen ringförmigen Kragen 213 mit drei Referenzlaschen 213a aufweist. Der ringförmige Kragen 213 ist mit der ersten Metallhülse 211 verschweißt, so dass die Zylinderachsen der beiden Metallhülsen 211, 212 entweder koaxial oder parallel versetzt angeordnet sind. Die drei Referenzlaschen 213a stehen von der Mantelfläche der zweiten hohlzylindrischen Metallhülse 212 ab, erstrecken sich jeweils in Richtung eines Durchmessers der zweiten Metallhülse 212 und sind äquidistant entlang des Umfangs des ringförmigen Kragens 213 angeordnet. Die dem Dichtungsring 23 zugewandte Unterseite der drei Referenzlaschen 213a definiert eine im wesentlichen senkrecht zur Zylinderachse der Metallhülse 211 und des Lampengefäßabschnitts 12 orientierte Referenzebene R zur Ausrichtung der Halogenglühlampe im Fahrzeugscheinwerfer. Sie entspricht der in der Norm ECE 324 Regel 37 zitierten Referenzebene. Zum Metallsockelteil 21 gehört ferner auch das bereits oben erwähnte, konisch ausgebildete metallische Halterteil 214, das zur Halterung des abgedichteten Endes 11 des Lampengefäßes 1 dient. Die Höhe B des Lampensockels 2 über der Referenzebene R beträgt ca. 13,6 mm.The
