Description

Die Erfindung betrifft eine elektrische Glühlampe gemäß des Oberbegriffs des Patentanspruchs 1.The invention relates to an electric incandescent lamp according to the preamble of the claim 1.

I. Stand der Technik I. State of the art

Eine derartige Glühlampe ist in der Offenlegungsschrift DE 101 45 427 Al offenbart. Diese Schrift beschreibt eine Halogenglühlampe für einen Fahrzeugscheinwerfer, die zwei in einem Lampengefäß eingeschlossene Glühwendeln zur Erzeugung des Abblendlichts beziehungsweise Fernlichts aufweist. Die zur Erzeugung des Fernlichts dienende Hauptwendel ist transversal zur Lampenachse ausgerichtet und ihre von einer Molybdänfolie umhüllten Wendelabgänge sind jeweils mit einem Stromzuführungsdraht verschweißt. Die zur Erzeugung des Abblendlichts dienende Nebenwendel ist axial in dem Lampengefäß ausgerichtet und besitzt einen quer zu ihrer Wickelachse verlaufenden, mit einer Molybdänfolie umhüllten Wendelabgang, der mit dem Ende eines Stromzuführungsdrahtes verschweißt ist. Der andere Wendelabgang dieser Glühwendel ist mit einer aus einem Molybdänblech gefertigten Abblendkappe verschweißt.Such an incandescent lamp is disclosed in the published patent application DE 101 45 427 A1. This document describes a halogen incandescent lamp for a vehicle headlight, the two enclosed in a lamp vessel incandescent filaments for generating having the low beam or high beam. The for the production of the high beam Serving main coil is aligned transversely to the lamp axis and their Wound outlets enveloped by a molybdenum foil are each connected to a power supply wire welded. The auxiliary spiral serving to produce the low beam is axially aligned in the lamp vessel and has a transverse to her Winding axis extending, wrapped with a molybdenum foil Wendelabgang, the welded to the end of a power supply wire. The other spiral outlet This filament is made with a made of a molybdenum shield welded.

Ein Nachteil der oben beschriebenen Wendelaufhängung Nebenwendel besteht darin, dass Ungenauigkeiten beim Wickeln der Glühwendel zu mechanischen Spannungen in der Glühwendel und sogar zur Torsion der Glühwendel führen können. Wird beispielsweise bei dem Wicklungsprozess der Nebenwendel eine Viertelwindung zuviel oder zuwenig erzeugt, so zeigt mindestens einer der Wendelabgänge der Nebenwendel in die falsche Richtung und kann dann nicht ohne Deformation der Glühwendel oder des Wendelabganges mit der Stromzuführung verschweißt werden. A disadvantage of the above-described helical suspension secondary helix is that that inaccuracies when winding the filament to mechanical stresses in the filament and even lead to the twist of the filament. For example in the winding process of the auxiliary coil a quarter turn too much or too little generated, so at least one of the spiral outlets of the secondary spiral shows in the wrong direction and then can not without deformation of the filament or the Wendelabganges be welded to the power supply.

II. Darstellung der Erfindung II. Presentation of the invention

Es ist die Aufgabe der Erfindung, eine elektrische Glühlampe mit einer verbesserten Wendelaufhängung bereitzustellen. Insbesondere soll trotz etwaiger Ungenauigkeiten bei der Wicklung der Glühwendel eine Befestigung der Glühwendel an den Stromzuführungen ohne das Verursachen von mechanischen Spannungen in der Glühwendel ermöglicht werden.It is the object of the invention to provide an electric incandescent lamp with an improved To provide coil suspension. In particular, despite any inaccuracies in the winding of the filament, a fastening of the filament to the power supply lines without causing mechanical stresses in the filament be enabled.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Besonders vorteilhafte Ausführungen der Erfindung sind in den abhängigen Patentansprüchen beschrieben.This object is achieved by the features of claim 1 solved. Particularly advantageous embodiments of the invention are in the dependent Claims described.

Die erfindungsgemäße elektrische Glühlampe besitzt mindestens eine innerhalb eines Lampengefäßes angeordnete Glühwendel und Stromzuführungen für diese Glühwendel, wobei mindestens eine der Stromzuführungen ein abgewinkeltes Ende aufweist, das mit einem quer zur Wickelachse der mindestens einen Glühwendel verlaufenden Wendelabgang der mindestens einen Glühwendel verbunden ist und wobei dieses abgewinkelte Ende und der vorgenannte Wendelabgang in einer Ebene quer zur Wickelachse der mindestens einen Glühwendel angeordnet sind.The electric incandescent lamp according to the invention has at least one inside a Lamp vessel arranged filament and power supply for this filament, wherein at least one of the power supply lines has an angled end, with a transverse to the winding axis of the at least one filament Wendelabgang the at least one filament is connected and wherein this Angled end and the aforementioned spiral outlet in a plane transverse to the winding axis the at least one filament are arranged.

Dadurch ist gewährleistet, dass der mit dem abgewinkelten Ende der Stromzuführung zu verbindende Wendelabgang der mindestens einen Glühwendel auch im Fall von Ungenauigkeiten bei dem Wickeln der Glühwendel mit der Stromzuführung verbindbar ist, ohne dass in der Glühwendel mechanische Spannungen verursacht werden. Besitzt die Glühwendel aufgrund von Fertigungstoleranzen beim Wicklungsprozess den Bruchteil einer Windung zuviel oder zuwenig, so ändert sich der Winkel zwischen dem Wendelabgang der Glühwendel und dem abgewinkelten Ende der Stromzuführung, wodurch sich die Verbindungsstelle zwischen dem Wendelabgang und der Stromzuführung auf dem abgewinkelten Ende der Stromzuführung entsprechend verschiebt. Weist beispielsweise die in Figur 1 abgebildete Glühwendel den Bruchteil einer Windung zuwenig auf, so wandert die Verbindungsstelle zwischen dem Wendelabgang und dem abgewinkelten Ende der Stromzuführung in Richtung der Stirnseite des abgewinkelten Endes, wenn der andere Wendelabgang der Glühwendel als räumlich fixiert angesehen wird. Entsprechend wandert die Verbindungsstelle zwischen dem Wendelabgang und dem abgewinkelten Ende der Stromzuführung auf dem abgewinkelten Ende in die entgegengesetzte Richtung, wenn die Glühwendel den Bruchteil einer Windung zuviel besitzt. Die erfindungsgemäße Wendelaufhängung ermöglicht daher in den obengenannten Fällen eine zuverlässige Fixierung der Glühwendel an ihren Stromzuführungen, ohne mechanische Spannungen in der Glühwendel zu hervorzurufen.This ensures that the with the angled end of the power supply to be connected Wendelabgang the at least one filament also in the case of Inaccuracies in the winding of the filament with the power supply connectable is without causing mechanical stresses in the filament. Has the filament due to manufacturing tolerances in the winding process If the fraction of a turn is too much or too little, the angle changes between the spiral outlet of the filament and the angled end of the Power supply, which causes the connection point between the spiral outlet and the power supply on the angled end of the power supply accordingly shifts. For example, has the filament shown in Figure 1 the A fraction of a turn too little on, so wanders the junction between the spiral outlet and the angled end of the power supply in the direction the end face of the angled end, if the other spiral outlet of the filament is considered spatially fixed. Accordingly, the junction wanders between the helical outlet and the angled end of the power supply on the angled end in the opposite direction when the Filament has a fraction of a turn too much. The inventive Helical suspension therefore allows a reliable in the above cases Fixing the filament to its power supply, without mechanical stresses in the filament to cause.

Die Länge des abgewinkelten Endes der Stromzuführung beträgt vorzugsweise einen Wert im Bereich von ca. 1 mm bis 5 mm. Dadurch können alle beim Wicklungsprozess der Glühwendel üblicherweise vorkommenden Fertigungstoleranzen berücksichtigt werden. Gemäß der bevorzugten Ausführungsbeispiele der Erfindung sind das abgewinkelte Ende der Stromzuführung und der damit verbundene Wendelabgang der mindestens einen Glühwendel vorzugsweise in einer Ebene senkrecht zur Wickelachse der vorgenannten Glühwendel angeordnet.

This allows everyone in the winding process the filament usually occurring manufacturing tolerances considered become. According to the preferred embodiments of the invention are the angled end of the power supply and the associated Wendelabgang the at least one filament preferably in a plane perpendicular to Winding axis of the aforementioned filament arranged. This can cause kinks or bending points in the spiral outlet can be avoided.

Die mit dem vorgenannten abgewinkelten Ende ausgestattete Stromzuführung ist aus fertigungstechnischen Gründen vorzugsweise als Draht ausgebildet. Das abgewinkelte Ende der Stromzuführung kann abgeflacht ausgebildet sein, um eine gute Schweißverbindung mit dem Wendelabgang der mindestens einen Glühwendel zu ermöglichen. Der vorgenannte Wendelabgang kann ferner von einer Molybdänfolie umhüllt sein, um eine gute Schweißverbindung zwischen der Glühwendel und der vorzugsweise aus Molybdän bestehenden Stromzuführung zu gewährleisten.The power supply equipped with the aforementioned angled end is off manufacturing reasons, preferably formed as a wire. The angled End of the power supply can be formed flattened to a good Welded connection with the spiral outlet of at least one filament to enable. The aforementioned Wendelabgang can also from a molybdenum foil Wrapped to be a good weld between the filament and the preferably to ensure existing power supply molybdenum.
