Dazu ist erfinderisch vorgesehen, dass die Hochdruckgasentladungslampe für eine Beleuchtungseinrichtung, insbesondere für einen Scheinwerfer eines Kraftfahrzeuges, mit einer Zündelektronik zusammenwirkt, die innerhalb eines Sockelgehäuses angeordnet ist, dass das Sockelgehäuse ein Oberteil und einen Deckel aufweist, wobei das Oberteil mit einer Öffnung ausgeführt ist, innerhalb dieser eine hochspannungsführende Verbindung zwischen der Hochdruckgasentladungslampe und der Zündelektronik sich befindet, dass der Deckel in die Öffnung hineinragt und die Öffnung isolierend verschließt, und dass die einander zugewandten Flächen des Oberteil und des Deckels ein Labyrinth bilden, das durch ein Isolationselement unterbrochen ist. Das Isolationselement ermöglicht zum einen eine Verkürzung des Labyrinths und zum anderen eine verbesserte Isolierung der hochspannungsführenden Verbindung zwischen dem Deckel und dem Oberteil. Hierdurch wird ein Platz sparender Aufbau der Hochdruckgasentladungslampe erzielt.For this purpose, it is inventively provided that the high-pressure gas discharge lamp for a lighting device, in particular for a headlight of a motor vehicle, cooperates with an ignition electronics, which is arranged within a base housing, that the base housing has a top and a lid, wherein the upper part is designed with an opening, within this is a high-voltage connection between the high pressure gas discharge lamp and the ignition electronics is that the lid protrudes into the opening and the opening closes insulating, and that the mutually facing surfaces of the upper part and the lid form a labyrinth, which is interrupted by an insulating element. The insulation element allows for a shortening of the labyrinth and on the other hand, an improved insulation of the high-voltage connection between the lid and the upper part. As a result, a space-saving construction of the high-pressure gas discharge lamp is achieved.
Erfindungsgemäß ist vorgesehen, dass das Isolationselement einen umlaufend geschlossenen Ring bildet. Vorteilhaft ist hierbei, wenn der umlaufend geschlossene Ring einen Kreis, ein Oval oder eine rechteckige Grundform aufweist. Die Form des Isolationselementes ist abhängig vom Umfang des Labyrinths. Besonders vorteilhaft ist zudem, wenn das Isolationselement wenigstens mit einem der folgenden Querschnitte ausgeführt ist: rund, oval oder eckig. Der jeweilige Querschnitt des Isolationselements ist abhängig von der Kontur des abzudichtenden Bereiches und/oder seiner Positionierung innerhalb des Labyrinths.According to the invention it is provided that the insulation element forms a circumferentially closed ring. It is advantageous here if the circumferentially closed ring has a circle, an oval or a rectangular basic shape. The shape of the insulation element depends on the circumference of the labyrinth. In addition, it is particularly advantageous if the insulation element is designed with at least one of the following cross sections: round, oval or angular. The respective cross section of the insulation element is dependent on the contour of the region to be sealed and / or its positioning within the labyrinth.
Vorteilhafterweise ist das Isolationselement als elastischer Dichtring ausgeführt. Als besonders vorteilhaft hat es sich erwiesen, wenn der Dichtring aus einem elastischen Polymer ausgeführt ist. Der Dichtring aus einem elastischen Polymer kann sich durch Verformung seiner anliegenden Oberfläche innerhalb des Labyrinthes formschlüssig anpassen und so eine hochspannungssichere Abschirmung bilden.Advantageously, the isolation element is designed as an elastic sealing ring. It has proved to be particularly advantageous if the sealing ring is made of an elastic polymer. The sealing ring made of an elastic polymer can adapt positively by deformation of its adjacent surface within the labyrinth and thus form a high-voltage-proof shield.
Das Isolationselement kann am Oberteil und/oder am Deckel angeordnet sein. Als vorteilhaft hat sich hierbei herausgestellt, wenn das Isolationselement direkt an das Oberteil und/oder am Deckel angespritzt ist. Durch das Anspritzen des Isolationselements kann eine zuverlässige Fixierung des Isolationselements innerhalb des Labyrinths gewährleistet werden, wobei gleichzeitig die Montagefreundlichkeit erhöht wird. Alternativ wäre ein Ankleben des Isolationselements ebenfalls denkbar.The insulation element can be arranged on the upper part and / or on the cover. It has proven to be advantageous in this case if the insulation element is molded directly onto the upper part and / or on the cover. By injecting the insulation element, a reliable fixation of the insulation element can be ensured within the labyrinth, at the same time the ease of assembly is increased.

In einer weiteren Ausführung der Erfindung ist vorgesehen, dass das Oberteil und/oder der Deckel innerhalb des Labyrinths mit einer Nut ausgestaltet ist/sind, in der das Isolationselement lösbar befestigt ist.

The geometry of the groove is in this case designed such that the insulating element is held positively in the groove.
In einer weiteren bevorzugten Ausführungsform ist die Kontur des Isolationselements lamellenförmig ausgestaltet. Auf Grund einer lamellenförmigen Ausgestaltung des Isolationselements wirkt in einer Endposition des Deckels und des Oberteils eine Kraft innerhalb des Labyrinths, die den Deckel am Oberteil hält. Das Isolationselement kann sowohl ein- oder mehrlamellig ausgeführt sein. Besonders vorteilhaft ist es, wenn das Isolationselement innerhalb des Labyrinths mit einer Kraft sowohl auf den Deckel als auch auf das Oberteil wirkt. Durch diese isolatorische Maßnahme kann eine Verbesserung der Abschirmung innerhalb des Labyrinths erreicht werden. Ferner kann das Isolationselement einen Querschnitts-Durchmesser von 0,5 mm ≤ x ≤ 4 mm aufweisen. Der Durchmesser des Isolationselements kann sowohl von der Elastizität des Isolationselements als auch vom Durchmesser des Labyrinths abhängig sein.In a further preferred embodiment, the contour of the insulation element is designed like a louver. Due to a lamellar configuration of the insulation element acts in an end position of the lid and the upper part of a force within the labyrinth, which holds the lid on the upper part. The insulation element can be designed either single or multi-lamellar. It is particularly advantageous if the insulation element acts within the labyrinth with a force both on the cover and on the upper part. By this isolatorische measure an improvement of the shielding can be achieved within the labyrinth. Further, the insulating member may have a cross-sectional diameter of 0.5 mm ≦ x ≦ 4 mm. The diameter of the insulating element can be dependent both on the elasticity of the insulating element and on the diameter of the labyrinth.
Eine weitere erfinderische Maßnahme sieht vor, dass wenigstens zwei Isolationselemente innerhalb des Labyrinths angeordnet sind. Die Anordnung von wenigstens zwei Isolationselementen innerhalb des Labyrinths erhöht die Abschirmung bei gleicher Labyrinthlänge. Insbesondere Hochdruckgasentladungslampen mit zwei oder drei Isolationselementen haben sich als besonders guter Kompromiss zwischen Anzahl, Kosten und Effektivität der Isolationselemente erwiesen.A further inventive measure provides that at least two isolation elements are arranged within the labyrinth. The arrangement of at least two isolation elements within the labyrinth increases the shielding at the same labyrinth length. In particular, high-pressure gas discharge lamps with two or three insulation elements have proven to be a particularly good compromise between the number, cost and effectiveness of the insulation elements.
Vorteilhafterweise sind die Isolationselemente miteinander verbunden. Hierbei ist eine stoffschlüssige Verbindung, insbesondere durch Verkleben und/oder Verschweißen der einzelnen Isolationselemente denkbar. Besonders vorteilhaft ist die Verbindung der Isolationselemente mittels eines Trägerelements. Dabei kann das Trägerelement umfänglich in dem Oberteil und/oder an dem Deckel angeordnet sein. Des Weiteren kann das Isolationselement auf und/oder an dem Trägerelement angeordnet sein. Die Isolationselemente und das Trägerelement können materialeinheitlich ausgeführt und/oder an das Oberteil und/oder den Deckel angespritzt sein. Sämtliche Merkmale und Details des Isolationselements bezüglich Anordnung, Ausgestaltung und Materialauswahl gelten dabei auch für das Trägerelement. Das Trägerelement trägt zusätzlich dazu bei, dass ein Durchschlagen der Hochspannung von der hochspannungsführenden Verbindung verhindert wird.Advantageously, the insulation elements are interconnected. Here, a cohesive connection, in particular by gluing and / or welding of the individual insulation elements is conceivable. Particularly advantageous is the connection of the insulation elements by means of a carrier element. In this case, the carrier element can be arranged circumferentially in the upper part and / or on the lid. Furthermore, the insulation element can be arranged on and / or on the carrier element. The insulation elements and the support element can be made of the same material and / or molded onto the upper part and / or the cover. All features and details of the insulation element with respect to arrangement, design and material selection also apply to the support element. The carrier element additionally contributes to preventing a breakdown of the high voltage from the high-voltage-carrying connection.
Besonders vorteilhaft ist es, wenn das Isolationselement in einem, in Verschlussrichtung des Deckels verlaufenden Kanal des Labyrinths angeordnet ist. Bei der Lagerung des Isolationselements in einem in Verschlussrichtung des Deckels verlaufenden Kanal des Labyrinths wirkt eine Kraft, die durch die Verformung des Isolationselements entsteht und den Deckel am Oberteil hält.It is particularly advantageous if the insulation element is arranged in a channel of the labyrinth running in the direction of closure of the cover. During the storage of the insulation element in a running in the closing direction of the lid channel of the labyrinth acts a force that arises due to the deformation of the insulating element and holds the lid on the upper part.
Des Weiteren kann es sinnvoll sein, den Labyrinthweg mit definierten Ausgestaltungen des Deckels und des Oberteils zu verlängern. Hierzu kann das Oberteil ein erstes Kragenelement aufweisen, das die Öffnung umfangsseitig umschließt. In einer weiteren Ausführungsform kann innerhalb der Öffnung ein Sockelelement angeordnet sein, das sich gegen die Verschlussrichtung des Deckels innerhalb der Öffnung erstreckt. Am freien Ende des Sockelelements kann die hochspannungsführende Verbindung verlaufen.Furthermore, it may be useful to extend the Labyrinthweg with defined embodiments of the lid and the upper part. For this purpose, the upper part may have a first collar element which surrounds the opening on the circumferential side. In a further embodiment, a base element can be arranged within the opening, which extends against the closure direction of the lid within the opening. At the free end of the base element, the high-voltage-carrying connection can run.
Ferner ist es denkbar, dass am Deckel ein mit der Öffnung korrespondierendes Verschlusselement angeordnet ist. Des Weiteren kann der Deckel ein zweites Kragenelement aufweisen. Hierbei kann es sinnvoll sein, wenn das zweite Kragenelement das Verschlusselement ringförmig umschließt. In einer Endposition des Deckels und des Oberteils ist sowohl ein Umschließen des zweiten Kragenelementes und des Verschlusselementes durch das erste Kragenelement, als auch ein verzahntes Eingreifen des ersten Kragenelementes zwischen das zweite Kragenelement und das Verschlusselement denkbar. Hierbei kann es sinnvoll sein, dass die Form des ersten Kragenelementes mit der Form des zweiten Kragenelementes und/oder des Verschlusselementes korrespondiert.Furthermore, it is conceivable that a closure element corresponding to the opening is arranged on the cover. Furthermore, the lid may have a second collar element. It may be useful if the second collar element surrounds the closure element in an annular manner. In an end position of the lid and the upper part both enclosing the second collar element and the closure element by the first collar element, as well as a toothed engagement of the first collar element between the second collar element and the closure element is conceivable. It may be useful that the shape of the first collar element corresponds to the shape of the second collar element and / or the closure element.
