Description

Die Erfindung betrifft eine elektrische Lampe für einen Fahrzeugscheinwerfer gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to an electric lamp for a vehicle headlight according to the preamble of claim 1.

I. Stand der Technik I. State of the art

Eine derartige elektrische Lampe ist beispielsweise in den internationalen Patentanmeldungen WO 97/25733 FR-A-2 557 357 und FR-A-2 557 358 offenbart. Diese Offenlegungsschrift beschreibt eine elektrische Glühlampe, insbesondere eine Kraftfahrzeugscheinwerferlampe, mit einer in einem gläsernen Lampenkolben eingeschlossenen Glühwendel und einem aus Metall- und Kunststoffteilen bestehenden Lampensockel. Der gasdicht verschlossene Quetschfuß des Lampenkolbens ist in einem metallischen Halterteil fixiert, das seinerseits direkt oder über einen Zwischenring mit einer metallischen, ringförmigen Trägerhülse verbunden ist. Die metallische Trägerhülse ist in dem mit den elektrischen Anschlüssen der Lampe ausgestatteten Kunststoffsockelteil des Lampensokkels verankert. Zur Montage der Lampe in der als Lampenfassung ausgebildeten Öffnung eines Reflektors besitzt die ringförmige Trägerhülse drei in einer Ebene angeordnete, äquidistant über der Umfang der Trägerhülse verteilte Referenznasen, die in die Lampen-Montage-Öffnung des Reflektors eingreifen, und eine radial nach außen wirkende Andruckfeder, die federnd am Rand der Lampen-Montage-Öffnung des Reflektors anliegt. Die Abdichtung der Montage-Öffnung des Reflektors erfolgt mittels eines Silikon- oder Gummiringes, der zwischen der Reflektoraußenwand und dem ringförmigen Flansch des Kunststoffsockelteils angeordnet ist. Ein Nachteil dieser Lampe besteht dann, daß die Kunststoffläche des Flansches durch die Montage-Öffnung des Reflektors für die von der Glühwendel emittierte elektromagnetische Strahlung zugänglich ist. Diese Kunststoffläche wird durch die von der Glühwendel emittierte Infrarotstrahlung und zusätzlich durch die Absorption des von der Glühwendel erzeugten Lichts erhitzt und neigt zum Ausdampfen. Außerdem vermindert die vorgenannte Lichtabsorption den Wirkungsgrad des Scheinwerfers.Such an electric lamp is for example in the international patent applications WO 97/25733 FR-A-2 557 357 and FR-A-2 557 358. This publication describes an electrical Incandescent lamp, in particular a motor vehicle headlamp, with an in an incandescent filament enclosed in a glass lamp bulb and a metal filament and plastic parts existing lamp base. The gas-tight sealed Pinch of the lamp bulb is fixed in a metallic holder part, which in turn directly or via an intermediate ring with a metallic, annular Carrier sleeve is connected. The metallic carrier sleeve is in the electric Terminals of the lamp equipped plastic base part of the lamp socket anchored. For mounting the lamp in the lamp socket designed as Opening of a reflector has the annular support sleeve three in a plane arranged, distributed equidistantly over the circumference of the support sleeve distributed reference noses, which engage in the lamp mounting opening of the reflector, and a radially after external pressure spring, the spring on the edge of the lamp mounting hole of the reflector is applied. The sealing of the mounting opening of the reflector takes place by means of a silicone or rubber ring, between the reflector outer wall and the annular flange of the plastic base part is arranged. A disadvantage this lamp is then that the plastic surface of the flange through the mounting hole of the reflector for the emitted from the filament electromagnetic Radiation is accessible. This plastic surface is characterized by that of the filament emitted infrared radiation and additionally by the absorption of the filament heated light and tends to evaporate. Also diminished the aforementioned light absorption the efficiency of the headlamp.

II Darstellung der Erfindung II illustration of the invention

Es ist die Aufgabe der Erfindung, eine Fahrzeugscheinwerferlampe bereitzustellen, die beim Einsatz in einem Scheinwerfer ein verringertes Ausdampfverhalten und einen verbesserten Wirkungsgrad gewährleistet.It is the object of the invention to provide a vehicle headlamp, when used in a headlight a reduced evaporation behavior and ensures improved efficiency.

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

Erfindungsgemäß sind die dem Lampenkolben zugewandten Flächen des Kunststoffsockelteils mit einer lichtreflektierenden Beschichtung versehen, die als Blech ausgebildet ist, das in wesentlichen den gleichen Lichtreflexionsgrad wie die Reflexionsfläche des Fahrzeugscheinwerferreflektors besitzt. Die lichtreflektierende Blech reduziert die Lichtabsorption des Kunststoffsockelteils und vermindert dadurch dessen thermische Belastung und verbessert somit das Ausdampfverhalten des Kunststoffsockelteils. Zusätzlich erhöht die lichtreflektierende Beschichtung die Effizienz des Scheinwerfers, da das auf die Kunststofflächen auftreffende Licht nun durch deren lichtreflektierende Beschichtung für den Scheinwerferreflektor nutzbar gemacht wird.The vehicle headlamp according to the invention has a lamp base, a translucent lamp envelope and at least one of the lamp envelope enclosed light source, the lamp base with the electrical connections the lamp provided plastic base part and at least one in the Plastic base part anchored metallic holder part for the lamp envelope. According to the invention the lamp envelope facing surfaces of the Plastic base part provided with a light-reflecting coating, which is designed as a sheet, which essentially the same light reflectance as the reflection surface of the Vehicle headlight reflector has. The Light-reflecting sheet reduces the light absorption of the plastic base part and thereby reduces its thermal load and thus improves the Evaporation behavior of the plastic base part. In addition, the light-reflecting increases Coating the efficiency of the headlamp, as that on the plastic surfaces incident light now by their light-reflecting coating for the headlight reflector is made usable.

Vorteilhafterweise ist die lichtreflektierende Beschichtung als Aluminiumblech ausgeführt, die die dem Lampenkolben zugewandten Kunststofflächen des Lampensockels abdeckt und dessen dem Lampenkolben zugewandte Seite poliert ist.Advantageously, the light-reflecting coating is aluminum sheet executed, which the lamp bulb facing Plastic surfaces of the lamp cap covers and the lamp bulb facing side is polished.
