II. Darstellung der ErfindungII. Presentation of the invention
Es ist Aufgabe der Erfindung, eine gattungsgemäße Hochdruckentladungslampe mit einer verbesserten elektromagnetischen Abschirmung für den Sockel bereitzustellen.It is the object of the invention, a generic High pressure discharge lamp with an improved electromagnetic Provide shielding for the socket.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Besonders vorteilhafte Ausführungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.These The object is achieved by the features of claim 1. Particularly advantageous designs The invention are defined in the dependent claims described.
Die erfindungsgemäße Hochdruckentladungslampe besitzt einen Sockel, in dem zumindest ein Lampengefäß der Hochdruckentladungslampe aufgenommen ist und in dessen Inneren Komponenten einer Zündvorrichtung zum Zünden der Gas entladung in der Hochdruckentladungslampe angeordnet sind und der mit einer elektromagnetischen Abschirmung versehen ist, die erfindungsgemäß von mindestens einer elektrisch leitenden Folie gebildet wird. Dadurch kann das zweiteilige Aluminiumgehäuse gemäß dem Stand der Technik eingespart werden und es ergeben sich als Vorteile eine Kostenreduktion, eine Gewichtsreduktion um ca. 16 Prozent und eine Reduktion des Volumens um ca. 14 Prozent bei der Hochdruckentladungslampe sowie eine Vereinfachung der Montage und eine Verringerung der Anzahl der Fertigungsschritte.The has high pressure discharge lamp according to the invention a pedestal in which at least one lamp vessel of the High-pressure discharge lamp is included and in its interior components an ignition device for igniting the gas discharge are arranged in the high pressure discharge lamp and with a provided electromagnetic shielding according to the invention of at least one electrically conductive film is formed. Thereby can the two-piece aluminum housing according to the State of the art can be saved and there are advantages a cost reduction, a weight reduction of about 16 percent and a reduction in volume of about 14 percent in the high-pressure discharge lamp as well as a simplification of the assembly and a reduction of the number the manufacturing steps.
Vorteilhafterweise ist die mindestens eine elektrisch leitende Folie als Metallfolie oder als Folie, die mindestens eine Metallschicht enthält, ausgebildet. Derartige Folien besitzen eine ausreichende Festigkeit und Hitzebeständigkeit und sind als vorgefertigte Komponenten im Handel erhältlich. Beispielsweise kann eine Aluminiumfolie oder eine metallisierte Kunststofffolie, insbesondere eine mit einer Aluminiumschicht versehene Kunststofffolie, verwendet werden.advantageously, is the at least one electrically conductive foil as a metal foil or as a foil containing at least one metal layer, educated. Such films have sufficient strength and heat resistance and are as prefabricated components available in the stores. For example, an aluminum foil or a metallized plastic film, in particular one with a Aluminum layer provided plastic film, can be used.
Die mindestens eine elektrisch leitende Folie ist vorteilhafterweise mittels einer Klebeverbindung am Sockel befestigt, um eine einfach herstellbare und sichere Haftung am Sockel zu gewährleisten. Gemäß einem bevorzugten Ausführungsbeispiel der Erfindung ist die mindestens eine elektrisch leitende Folie selbstklebend ausgebildet, das heißt, die mindestens eine elektrisch leitende Folie besitzt vorzugsweise eine Klebeschicht, welche die Klebeverbindung mit dem Sockel erzeugt.The at least one electrically conductive film is advantageously attached to the base by means of an adhesive joint to make it easy to ensure manufacturable and secure adhesion to the base. According to one preferred embodiment of the invention is the at least an electrically conductive film is self-adhesive, that is, the at least one electrically conductive film preferably has an adhesive layer which creates the adhesive bond with the pedestal.
Vorteilhafterweise ist die mindestens eine elektrisch leitende Folie bedruckbar, um sie bzw. die Sockelfläche, auf der sie angeordnet ist, zur Kennzeichnung der Hochdruckentladungslampe nutzen zu können.advantageously, the at least one electrically conductive foil is printable to they or the base surface on which it is arranged, to use for marking the high pressure discharge lamp.
Um eine ausreichende elektromagnetische Abschirmung zu gewährleisten, genügt es, diejenigen Wände des Sockels mit der mindestens einen Folien zu versehen, die das Innere des Sockels umschließen, in dem die elektrischen Komponenten der Zündvorrichtung bzw. Betriebsvorrichtung angeordnet sind. Die mindestens eine elektrisch leitende Folie kann auf der Innenseite oder Außenseite der vorgenannten Wände angeordnet sein.Around to ensure adequate electromagnetic shielding it suffices to cover those walls of the base with the to provide at least one foil covering the interior of the pedestal enclose in which the electrical components of the ignition device or operating device are arranged. The at least one electric conductive foil can be on the inside or outside be arranged the aforementioned walls.
Die mindestens eine elektrisch leitende Folie kann außerdem in vorteilhafter Weise genutzt werden, um die elektromagnetische Abschirmung auf das Massebezugspotential eines Betriebsgerätes für die Hochdruckentladungslampe zu legen, indem die mindestens eine elektrisch leitende Folie mit einem elektrischen Anschluss der Hochdruckentladungslampe verbunden ist, der seinerseits mit einem auf Massepotential liegenden Gegenkontakt des Betriebsgerätes verbindbar ist. Ferner weist die mindestens eine elektrisch leitende Folie vorteilhafterweise eine elektrische Kontaktfläche auf, die zur Herstellung einer Massenkontaktierung in einem Scheinwerfermodul dient, wenn die Hochdruckentladungslampe in das Scheinwerfermodul montiert wird. Dadurch wird neben der elektromagnetischen Abschirmung auch eine hohe Sicherheit gewährleistet, da der Lampensockel und der Reflektor des Scheinwerfermoduls auf demselben elektrischen Potential liegen.The at least one electrically conductive foil may also be used in an advantageous manner to the electromagnetic Shielding to the ground reference potential of a control gear for the high pressure discharge lamp by the at least an electrically conductive foil with an electrical connection the high-pressure discharge lamp is connected, in turn with a lying at ground potential mating contact of the operating device is connectable. Furthermore, the at least one electrically conductive Foil advantageously an electrical contact surface on, for producing a mass contacting in a headlamp module Serves when the high pressure discharge lamp in the headlamp module is mounted. This will in addition to the electromagnetic shielding too ensures a high level of safety, as the lamp base and the reflector of the headlight module on the same electric Potential lie.
