Description

Die Erfindung betrifft eine Halogenglühlampe gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a halogen incandescent lamp according to the preamble of claim 1.

I. Stand der Technik I. State of the art

Eine derartige Halogenglühlampe ist beispielsweise in der EP 1 667 205 A2 offenbart. Diese Offenlegungsschrift beschreibt eine Halogenglühlampe mit zwei von einem Lampengefäß umschlossenen Glühfäden, die für unterschiedliche elektrische Leistungen ausgelegt sind. Der erste, für eine höhere elektrische Leistung ausgelegte Glühfaden dient beim Einsatz der Lampe in einem Kraftfahrzeugscheinwerfer zur Erzeugung des Fernlichts, während der zweite, für eine geringere elektrische Leistung ausgelegte Glühfaden zur Erzeugung eines Tagfahrlichts vorgesehen ist.Such a halogen incandescent lamp is for example in the EP 1 667 205 A2 disclosed. This publication describes a halogen incandescent lamp with two filaments enclosed by a lamp vessel, which are designed for different electrical powers. The first, designed for a higher electrical power filament is used when using the lamp in a motor vehicle headlight to produce the high beam, while the second, designed for a lower electrical power filament for generating a daytime running light is provided.

II. Darstellung der Erfindung II. Presentation of the invention

Es ist Aufgabe der Erfindung, eine gattungsgemäße Hälogenglühlampe bereitzustellen, bei welcher der niederwattige Glühfaden neben der Tagfahrlichtfunktion für eine weitere Beleuchtungsfunktion, insbesondere zur Realisierung einer Positionslichtfunktion verwendbar ist.It is an object of the invention to provide a generic Hälogenglühlampe, in which the niederwattige filament next to the daytime running light function for a further lighting function, in particular for the realization of a position light function is usable.

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

Die erfindungsgemäße Halogenglühlampe besitzt zwei, innerhalb eines Lampengefäßes angeordneten Glühfäden, wobei ein erster Glühfaden für den Betrieb mit einer höheren elektrischen Leistung als der zweite Glühfaden ausgelegt ist, und der zweite Glühfaden, zur Realisierung einer Tagfahrlichtfunktion, beim Betrieb mit einer Standardbetriebsspannung für eine elektrische Leistung ausgelegt ist, die um den Faktor 2,5 bis 4 kleiner als die elektrische Leistung des ersten Glühfadens ist, und derart konstruiert ist, dass er zur Realisierung einer Positionslichtfunktion in einem gedimmten Zustand mit einer Betriebsspannung kleiner als die Standardbetriebsspannung betreibbar ist. Insbesondere ist der zweite Glühfaden derart konstruiert, dass er für die Tagfahrlichtfunktion mit der Standardbetriebsspannung, das heißt, mit der Bordnetzspannung des Kraftfahrzeugs von nominal 13,2 V bzw. 28 V und einer elektrischen Leistung im Bereich von ca. 17 W bis 22 W betrieben wird und für die Positionslichtfunktion in einem gedimmten Zustand, das heißt, mit reduzierter Helligkeit und einer Betriebsspannung kleiner als die Standardbetriebsspannung betreibbar ist. Dadurch kann auf eine separate Lichtquelle für das Positionslicht bzw. Standlicht verzichtet werden.The halogen incandescent lamp according to the invention has two, disposed within a lamp vessel filaments, wherein a first filament for operation with a higher electric power is designed as the second filament, and the second filament, for realizing a daytime running light function, is designed to operate at a standard operating voltage for an electrical power that is smaller than the electrical power of the first filament by a factor of 2.5 to 4, and is constructed so as to be operable to realize a position light function in a dimmed state with an operating voltage lower than the standard operating voltage. In particular, the second filament is designed to operate at the standard operating voltage for the daytime running light function, that is, at the vehicle electrical system voltage of nominal 13.2 V or 28 V and electrical power in the range of approximately 17 W to 22 W, respectively is operable for the position light function in a dimmed state, that is, with reduced brightness and an operating voltage less than the standard operating voltage. This eliminates the need for a separate light source for the position light or parking light.

Vorteilhafterweise ist der zweite Glühfaden derart konstruiert ist, dass er für die Positionslichtfunktion mit einer Spannung im Bereich von 35 Prozent bis 95 Prozent der Standardbetriebsspannung betrieben wird. Dadurch wird die elektrische Leistung des zweiten Glühfadens in diesem Betriebsmodus auf einen Wert im Bereich von ca. 12 % bis 90 % des ursprünglichen Wertes begrenzt.Advantageously, the second filament is constructed to operate for the position light function at a voltage in the range of 35 percent to 95 percent of the standard operating voltage. This limits the electrical power of the second filament in this mode of operation to a value in the range of about 12% to 90% of the original value.

Der zweite Glühfaden ist erfindungsgemäß als einfach gewendelte Glühwendel ausgebildet ist, um eine homogene Lichtverteilung zu gewährleisten. Ihr Steigungsfaktor liegt im Bereich von größer oder gleich 1,65 und kleiner oder gleich 2,0, um eine niedrige Leuchtdichte zu erreichen und eine Blendung des Gegenverkehrs beim Tagfahrlichtbetrieb zu vermeiden. Der zweite Glühfaden emittiert aber trotz des vergleichsweise großen Steigungsfaktors auch im gedimmten Zustand, mit reduzierter Betriebsspannung und verringerter elektrischer Leistung, noch weißes Licht, das den Anforderungen an ein Positionslicht gerecht wird.The second filament is inventively designed as a simple coiled filament to ensure a homogeneous light distribution. Your gradient factor is in the range of greater than or equal to 1.65 and less than or equal to 2.0 in order to achieve a low luminance and to avoid dazzling of oncoming traffic in daytime running mode. Despite the comparatively large gradient factor, the second filament also emits white light in the dimmed state, with reduced operating voltage and reduced electrical power, which meets the requirements for position light.

Der erste Glühfaden ist vorzugsweise als Fernlichtglühfaden oder Nebellichtglühfaden ausgebildet.The first filament is preferably formed as a high-beam filament or Fogelichtglühfaden.

Um eine möglichst kleine Wolframabdampfrate bei beiden Glühfäden zu gewährleisten, ist der Innenraum des Lampengefäßes der erfindungsgemäßen Halogenglühlampe vorteilhafterweise mit einem Füllgas gefüllt, das ein Edelgas oder ein Edelgasgemisch, vorzugsweise aus einem oder mehreren der Edelgase Xenon, Krypton und Argon, enthält und einen Kaltfülldruck (das heißt, bei einer Temperatur von 25 Grad Celsius) im Bereich von 3 bar bis 18 bar aufweist.In order to ensure the smallest possible Wolframabdampfrate both filaments, the interior of the lamp vessel of the halogen incandescent lamp according to the invention is advantageously filled with a filling gas containing a noble gas or a noble gas mixture, preferably from one or more of the noble gases xenon, krypton and argon, and a cold filling ( that is, at a temperature of 25 degrees Celsius) in the range of 3 bar to 18 bar.

Der Halogenzusatz zum Füllgas umfasst vorzugsweise einen Anteil im Bereich von 20 ppm bis 450 ppm (parts per million), vorzugsweise in Form von Brom oder bzw. und Chlor, um eine Schwärzung des Lampengefäßes zu verhindern.The addition of halogen to the fill gas preferably comprises a proportion in the range of 20 ppm to 450 ppm (parts per million), preferably in the form of bromine and / or chlorine, to prevent blackening of the lamp vessel.

Die Glühwendeln 21, 22 sind als einfach gewendelte Wolframdrähte ausgebildet. Die Wendelabgänge 211, 212 bzw. 221, 222 der Glühwendeln 21 bzw. 22 sind jeweils mit einer Molybdänfolie umwickelt, die als Schweißhilfe beim Verschweißen der Wendelabgänge 211, 212 bzw. 221, 222 mit Stromzuführungen für die Glühwendeln 21, 22 dient. Ein abgedichtetes Ende 11 des Lampengefäßes 10 ist in einem Lampensockel 30 verankert. Die erste Glühwendel 21 ist teilweise von einer aus Molybdänblech geformten Abblendkappe 4 umgeben. Die Abblendkappe 4 wird von einem ersten Stromzuführungsdraht 51 getragen, der zusammen mit einem zweiten 52 und dritten Stromzuführungsdraht 53 zur Energieversorgung der beiden Glühwendeln 21, 22 dient. Zu diesem Zweck ist ein erster Wendelabgang 211 der ersten Glühwendel 21 durch eine Buckelschweißung mit einer Schweißfahne 41 der Abblendkappe 4 verschweißt und dadurch über die Abblendkappe 4 elektrisch leitend mit dem ersten Stromzuführungsdraht 51 verbunden.

Der Lampensockel 30 ist als Metall-Kunststoff-Sockel ausgebildet, der sowohl einen metallischen Sockelabschnitt 31 als auch einen aus Kunststoff bestehenden Sockelabschnitt 32 aufweist. In dem metallischen Sockelabschnitt 31 ist das Lampengefäß 10 verankert und der aus Kunststoff bestehende Sockelabschnitt 32 ist mit den elektrischen Kontakten 61, 62, 63 der Lampe versehen. Zur Montage der Halogenglühlampe in dem Scheinwerferreflektor dienen ein metallischer Federring mit drei Federlaschen 311 und drei Schlüssellaschen 312. Der Rand der Montageöffnung des Reflektors ist nach der Montage der Lampe in dem Scheinwerfer klemmend zwischen den Federlaschen 311 und den Schlüssellaschen 312 angeordnet.

The anti-dazzle device 4 is supported by a first power supply wire 51 which, together with a second 52 and third power supply wire 53, serves to energize the two filaments 21, 22. For this purpose, a first spiral outlet 211 of the first incandescent filament 21 is welded by a projection welding with a welding lug 41 of the antiglare cap 4 and thereby electrically connected to the first current supply wire 51 via the antiglare cap 4. The second coil outlet 212 of the first filament 21 is welded to the third power supply wire 53.
