Description

Lichtleitender Stabkörper, in welchen mittels einer Lichtquelle über mindestens eine seiner Stirnflächen Licht einspeisbar ist, der mit Mitteln zur Erzeugung einer über seine Mantelfläche unterschiedlichen Lichtemission versehen und in einer Fahrzeugkomponente angeordnet ist.light Lead Rod body, in which by means of a light source via at least one of his faces Light is feedable, with means of generating one over its lateral surface provided different light emission and in a vehicle component is arranged.

Ein gattungsgemäßer Stabkörper ist aus der Druckschrift EP 0 899 503 B1 bekannt. Er besteht aus einer Lichttransmissionsröhre mit einem lichtdurchlässigen Kern und einem Mantel mit einem relativ zum Kern niedrigeren Brechungsindex. Die Lichttransmissionsröhre weist auf ihrer Mantelfläche eine sich in Längsrichtung erstreckende, bandförmige Reflexionsschicht auf, mittels derer ein gerichteter Lichtaustritt über die Mantelfläche des Stabkörpers herbeiführbar ist. Ein derartiger Stabkörper kann beispielsweise als indirekte Beleuchtung an der inneren Längsseite eines Fahrzeugs angeordnet werden.A generic rod body is from the document EP 0 899 503 B1 known. It consists of a light transmission tube with a translucent core and a cladding with a lower refractive index relative to the core. The light transmission tube has on its lateral surface on a longitudinally extending, band-shaped reflection layer, by means of which a directed light emission over the lateral surface of the rod body can be brought about. Such a rod body can be arranged for example as indirect lighting on the inner longitudinal side of a vehicle.

Für eine direkte Beleuchtung ist dieser Stabkörper weniger geeignet, da der Fahrzeuginsasse bei dieser Anwendung Richtung und/oder Stärke der Lichtstrahlung beeinflussen sollte. Dies ist bei der vorbekannten Vorrichtung nicht möglich.For a direct Lighting is this rod body less suitable, as the vehicle occupant in this application direction and / or strength should influence the light radiation. This is in the known Device not possible.

Aus der Druckschrift US 2002/0126903 A1 ist bereits ein lichtemittierender, drehbarer Stabkörper für die Beleuchtung von Messgeräten o. dgl. bekannt. Der Stabkörper weist eine sich über einen Teilbereich seiner Radialfläche entlang seiner Längserstreckung verlaufende reflektierende Beschichtung auf. Das durch den verbleibenden Spalt austretende Licht kann durch Drehung des Stabs in seiner Richtung beeinflusst werden.Out US 2002/0126903 A1 is already a light-emitting, rotatable rod body for the Illumination of measuring instruments o. The like. Known. The rod body has one over a portion of its radial surface along its longitudinal extent extending reflective coating on. That by the remaining Gap escaping light can be achieved by rotating the rod in its direction to be influenced.

Der Erfindung liegt die Aufgabe zugrunde, eine auch zur direkten Beleuchtung im Innenraum eines Kraftfahrzeugs geeignete Vorrichtung bereitzustellen.Of the Invention is based on the object, one for direct lighting to provide suitable device in the interior of a motor vehicle.

Lösungsolution

Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Stabkörper um eine sich in seiner Längsrichtung erstreckende Längsachse relativ zur Fahrzeugkomponente drehbar ist. Durch Drehung des Stabkörpers können die Richtung der Lichtabstrahlung und, sofern die Lichtstrahlung ganz oder teilweise gegen die Fahrzeugkomponente gerichtet wird, auch die in den Fahrzeuginnenraum abgestrahlte Lichtmenge, mit einfachen technischen Mitteln und bei geringem Bauraum beeinflusst werden.The The object is achieved in that the rod body around one in its longitudinal direction extending longitudinal axis is rotatable relative to the vehicle component. By rotation of the rod body, the Direction of light emission and, provided the light radiation is complete or partially directed against the vehicle component, too the amount of light radiated into the vehicle interior, with simple technical means and in a small space can be influenced.

Der Stabkörper ist vorzugsweise nicht nur gegenüber der Fahrzeugkomponente, sondern auch relativ zu der drehfest in der Fahrzeugkomponente angeordneten Lichtquelle drehbar. Bei dieser Ausführung ist es möglich, den Stabkörper ohne Endanschläge oder Schleifkontakte endlos drehbar auszubilden.Of the rod body is preferably not only opposite the vehicle component, but also relative to the rotationally fixed in the vehicle component arranged light source rotatable. At this execution Is it possible, the rod body without limit stops or sliding contacts form endlessly rotatable.

Um den Bauaufwand weiter zu verringern, wird der Stabkörper mit mindestens einer Handhabe zur unmittelbaren Drehbetätigung ausgestattet. Diese ist als ringförmig um die Mantelfläche umlaufender, vorzugsweise auf seiner äußeren Radialfläche strukturierter Ring ausgebildet sein, der drehfest auf dem Stabkörper angeordnet ist und durch beispielsweise Spritzgießen unmittelbar an diesen anformbar ist.Around To further reduce the construction costs, the rod body with equipped with at least one handle for immediate rotary operation. This is as a ring around the lateral surface circumferential, preferably structured on its outer radial surface Ring be formed, which is arranged rotationally fixed on the rod body is and can be molded directly to this example by injection molding.

Die Mittel zur Erzeugung der Lichtemission können mit Vorteil eine vorzugsweise hochreflektierende Abschirmung umfassen. Alternativ ist denkbar, lichtstreuende Strukturen in oder auf dem Stabkörper vorzusehen. Dies können dreidimensionale Oberflächenstrukturen, Störstellen im Inneren des Stabkörpers oder auf seiner Mantelfläche angeordnete Farbmarkierungen sein. Zur Vereinfachung der Herstellung erstrecken sich die Mittel zur Lichtemission vorzugsweise über Teilbereiche seiner Mantelfläche, insbesondere zwischen seinen Stirnflächen.The Means for generating the light emission can advantageously a preferably comprise highly reflective shield. Alternatively, it is conceivable, light-scattering Provide structures in or on the rod body. This can three-dimensional surface structures, impurity inside the rod body or on its outer surface be arranged color marks. To simplify the production The light emission means preferably extend over partial areas its lateral surface, in particular between his faces.

Der lichtleitende Kern des Stabkörpers besteht mit Vorteil aus Polymethylmetacrylat, Polycarbonat oder Glas und hat einen kreisrunden Querschnitt. Er kann außenseitig mit einer Beschichtung aus einem Werkstoff mit einem gegenüber dem Kern niedrigeren Brechungsindex ausgestattet werden (Cladding), beispielsweise aus Acryllack oder Magnesiumdifluorid (MgF2). Diese Beschichtung verbessert die Lichtleitung im Stabkörper durch Herbeiführung einer Totalreflektion an seiner Mantelfläche.The photoconductive core of the rod body is advantageously made of polymethyl methacrylate, polycarbonate or glass and has a circular cross-section. On the outside, it can be provided with a coating of a material having a lower refractive index relative to the core (cladding), for example of acrylic lacquer or magnesium difluoride (MgF 2 ). This coating improves the light conduction in the rod body by causing a total reflection on its lateral surface.
