Abstract

The light (1) has a lighting surface provided at a vehicle part (3) e.g. vehicle door or rear deck. The lighting surface is formed by a shell surface of a light conductor (4), where the light conductor partially extends along an outer contour (2) of the vehicle part. The light conductor is flexible, and is fastened in a gasket by a clamp, where the gasket and the clamp are provided in the vehicle part. An independent claim is also included for a gasket for a vehicle part e.g. vehicle door or rear deck.

Description

Die vorliegende Erfindung betrifft eine Fahrzeugbeleuchtung mit einer an einem Fahrzeugteil, insbesondere Fahrzeugtür oder Kofferraumdeckel, vorgesehenen Leuchtfläche.The The present invention relates to a vehicle lighting with a on a vehicle part, in particular vehicle door or trunk lid provided Light area.

Für Beleuchtungen von Fahrzeugoberflächen sowie für Ambientebeleuchtungen im Fahrzeug werden Lichtquellen eingesetzt, deren emittiertes Licht mit Hilfe von glasklaren Kunststoffformteilen weitergeleitet und verteilt wird. Diese Lichtleiter bestehen in der Regel aus einem harten, thermoplastischen Kunststoff und werden in einem Spritzgussprozess urgeformt. Dazu werden üblicherweise Spritzgießwerkzeuge für den Herstellprozess verwendet. Allerdings muss für jedes einzelne Formteil ein speziell geformtes Stahlwerkzeug angefertigt werden, und außerdem ist der Spritzgießprozess ein diskontinuierlicher Prozess, der entsprechend hohe Kosten verursacht.For lighting of vehicle surfaces also for Ambient lights in the vehicle are used light sources, their emitted light with the help of crystal clear plastic moldings forwarded and distributed. These light guides usually consist of one hard, thermoplastic and are used in an injection molding process urgeformt. These are usually injection molds for the Manufacturing process used. However, for every single molded part one must specially shaped steel tool are made, and also the injection molding process a discontinuous process that causes correspondingly high costs.

Demgegenüber ist es die Aufgabe der vorliegenden Erfindung, bei einer Fahrzeugbeleuchtung der eingangs genannten Art Entwicklungs- und Herstellungskosten zu reduzieren und weitere Designfreiheitsgrade zu schaffen.In contrast, is it is the object of the present invention, in a vehicle lighting the to reduce the aforementioned development and production costs and to create more design degrees of freedom.

Diese Aufgabe wird in einem ersten Aspekt der Erfindung dadurch gelöst, dass die Leuchtfläche durch die Mantelfläche eines sich zumindest teilweise entlang der Außenkontur des Fahrzeugteils erstreckenden Lichtleiters gebildet ist.These The object is achieved in a first aspect of the invention in that the illuminated area through the lateral surface one at least partially along the outer contour of the vehicle part extending optical fiber is formed.

Erfindungsgemäß wird die Kontur eines Fahrzeugteils, wie z.B. die Kontur oder Außenkontur der Fahrzeugtür, eines sonstigen Karosserieteiles (z.B. Kofferraumdeckel), des Fahrzeugtürrahmens, des Tankdeckels, des Armaturenbretts, des Handschuhfachs, des Dachhimmels, etc., beleuchtet. Im Fall einer beleuchteten Fahrzeugtür-Außenkontur ist die geöffnete Fahrzeugtür bei Nacht für von hinten sich nähernde Verkehrsteilnehmer anhand des leuchtenden Lichtleiters erkennbar.According to the invention Contour of a vehicle part, such as the contour or outer contour of the Vehicle door, another body part (e.g., trunk lid), the vehicle door frame, the vehicle body Gas cap, dashboard, glove compartment, headliner, etc., illuminated. In the case of a lit vehicle door outer contour is the open one vehicle door at night for approaching from behind Road users recognizable by the luminous fiber optic.

Die oben genannte Aufgabe wird in einem zweiten Aspekt der Erfindung auch dadurch gelöst, dass die Leuchtfläche durch die Mantelfläche eines biegsamen Lichtleiters gebildet ist.The The above object is achieved in a second aspect of the invention also solved by that the illuminated area through the lateral surface a flexible light guide is formed.

Die wesentlichen Vorteile dieser erfindungsgemäßen Fahrzeugbeleuchtung mit biegsamem Lichtleiter sind:

  • – Reduzierung der Einmalkosten wegen nicht erforderlicher Spritzgusswerkzeuge;
  • – Reduzierung der Stückkosten, weil für den Lichtleiter Meterware verwendet werden kann;
  • – schnellere Herstellung und Anpassung an neue Artikelgeometrien;
  • – größere Designfreiheit durch biegsame Lichtleiter.
The main advantages of this vehicle lighting according to the invention with a flexible light guide are:
  • - Reduction of one-time costs due to unnecessary injection molding tools;
  • - Reduction of unit costs, because the optical fiber can be used by the meter;
  • - faster production and adaptation to new article geometries;
  • - greater freedom of design due to flexible light guides.

Der Lichtleiter kann beispielsweise aus biegsamem Kunststoffmaterial sein, so dass frei geformte Oberflächen damit ausgerüstet werden können. Es ist dann nicht mehr notwendig, für jeden Anwendungsfall ein Spritzgusswerkzeug anzufertigen. Vielmehr kann ein kontinuierlich hergestelltes Extrusionsprofil entsprechend abgelängt und eingebaut werden. Mit einem genormten Fassungselement kann eine Lichtquelle am Lichtleiter befestigt werden und somit die Einspeisung des Lichtes sicherstellen. Damit ergeben sich vollständig neue Perspektiven im Hinblick auf Designfreiheitsgrade sowie die flexible Anpassung an neue Gegebenheiten, da die teure und langwierige Herstellung eines Spritzgusswerkzeuges entfällt.Of the Optical fiber, for example, made of flexible plastic material so that free-formed surfaces are equipped with it can. It is then no longer necessary for each application To make injection mold. Rather, one can be continuous tailored extruded profile cut to length and to be built in. With a standardized socket element can a Light source be attached to the light guide and thus the feed of the light. This results in completely new Perspectives on design degrees of freedom and flexible customization to new circumstances, as the expensive and lengthy production an injection molding tool is eliminated.

Vorzugsweise ist der Lichtleiter über eine oder mehrere Halterungen befestigt, die am Fahrzeugteil vorgesehen sind. Diese Halterungen können in den Rand oder die Fläche der Türinnenverkleidung integriert sein. In einer besonders vorteilhaften Ausführungsform der Erfindung ist der Lichtleiter in einer am Fahrzeugteil vorgesehenen Dichtung befestigt, die dazu als Hart/Weich-Kombination ausgeführt sein kann.Preferably is the light guide over attached one or more brackets provided on the vehicle part are. These brackets can be in the edge or the surface the door interior panel integrated be. In a particularly advantageous embodiment of the invention the light guide is fixed in a seal provided on the vehicle part, the can be designed as a hard / soft combination.

Der Lichtleiter ist idealerweise ein Lichtleiterkabel, das auf die gewünschte Länge zugeschnitten ist.Of the Optical fiber is ideally an optical fiber cable that is cut to the desired length.

Die Erfindung betrifft auch eine Dichtung für ein Fahrzeugteil, insbesondere Fahrzeugtür oder Kofferraumdeckel, mit einer Befestigungsaufnahme, vorzugsweise Nut, für den Lichtleiter der oben beschriebenen Fahrzeugbeleuchtung.The The invention also relates to a seal for a vehicle part, in particular vehicle door or trunk lid, with a mounting receptacle, preferably Groove, for the light guide of the vehicle lighting described above.

Weitere Vorteile der Erfindung ergeben sich aus der Beschreibung und der Zeichnung. Ebenso können die vorstehend genannten und die noch weiter aufgeführten Merkmale je für sich oder zu mehreren in beliebigen Kombinationen Verwendung finden. Die gezeigten und beschriebenen Ausführungsformen sind nicht als abschließende Aufzählung zu verstehen, sondern haben vielmehr beispielhaften Charakter für die Schilderung der Erfindung.Further Advantages of the invention will become apparent from the description and the Drawing. Likewise the above-mentioned and the features further mentioned ever for to use one or more in any combination. The shown and described embodiments are not as final enumeration but rather have exemplary character for the description the invention.
