Abstract
Description
Die Erfindung betrifft eine Lichtleiterstruktur, insbesondere zur Verwendung in Kraftfahrzeugen, bei denen ein erster Lichtleitweg gebildet ist durch einen ersten Lichtleiterabschnitt, der mit einem Lichteinkoppelbereich eines Lichtleitelements verbunden ist, und bei der mindestens ein zweiter Lichtleitweg gebildet ist durch einen zweiten Lichtleiterabschnitt, der mit einem zweiten Lichteinkoppelbereich des Lichtleitelements verbunden ist.The The invention relates to a light guide structure, in particular for use in motor vehicles, in which a first Lichtleitweg is formed by a first optical waveguide section, which has a light coupling-in area a light-conducting element is connected, and wherein the at least one second Lichtleitweg is formed by a second optical fiber section, the connected to a second Lichteinkoppelbereich of the light guide is.
Solche Lichtleiterstrukturen werden beispielsweise bei Kraftfahrzeugen verwendet, um ein ansprechendes Nachtdesign zu schaffen.Such Optical fiber structures are used, for example, in motor vehicles used to create an appealing night design.
Das Lichtleitelement wird gemäß dem Stand der Technik von Lichtleiterabschnitten gespeist, die an Lichteinkoppelbereichen des Lichtleitelements münden.The Light guide is according to the prior Technology fed by fiber optic sections, which at Lichteinkoppelbereichen of the light-guiding element open.
Die bekannten Lichtleiterstrukturen haben den Nachteil, dass sie an beengte Einbauverhältnisse, wie sie vor allen Dingen bei Kraftfahrzeugen gegeben sind, nur bedingt anpassbar sind. Dies liegt auch daran, dass die Lichtleiterabschnitte oder Lichtleitelemente keine engen Radien aufweisen dürfen, da diese mit hohen Lichtverlusten einhergehen.The known optical fiber structures have the disadvantage that they are on cramped installation conditions, as they are given above all in motor vehicles, only conditionally are customizable. This is also because the fiber optic sections or light guide elements must not have narrow radii because These are accompanied by high light losses.
Ausgehend hiervor liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Lichtleiterstruktur zu schaffen, mit der eine effiziente und platzsparende Einkopplung von Licht in ein Lichtleitelement möglich ist.outgoing Here is the object of the present invention, a Fiber optic structure to create an efficient and space-saving Coupling of light in a light guide is possible.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Lichtleitwege sich gegenseitig durchdringen. Die Lichtleitwege verlaufen also nicht körperlich getrennt voneinander, sondern durchdringen sich, wodurch Bauraum eingespart werden kann. Gleichzeitig können vergleichsweise große Radien verwendet werden, wodurch die Lichtverluste minimiert werden.These Task is inventively characterized solved, that the optical paths penetrate each other. The optical paths So do not go physically separated from each other, but penetrate each other, creating space can be saved. At the same time comparatively large radii can be used which minimizes light losses.
Weiterhin wird vorgeschlagen, dass sich die Lichtleitwege kreuzend durchdringen. Diese Anordnung ermöglicht eine besonders kompakte Konstruktion.Farther It is suggested that the light paths penetrate crossing each other. This arrangement allows a particularly compact construction.
Wenn die Achsen der Lichtleiterabschnitte im Bereich der sich durchdringenden Lichtleitwege zwischen sich einen Winkel von ≤ 90° bilden, ist besonders gut gewährleistet, dass die Lichtverluste gering gehalten sind.If the axes of the optical fiber sections in the region of the penetrating Optical paths between them form an angle of ≤ 90 °, is particularly well ensured that the light losses are kept low.
Nach einer Weiterbildung der Erfindung sind der erste und/oder der zweite Lichteinkoppelbereich durch Endabschnitte des Lichtleitelements gebildet.To a development of the invention are the first and / or the second Lichteinkoppelbereich by end portions of the light guide educated.
Nach einer Weiterbildung der Erfindung sind der erste und/oder der zweite Lichteinkoppelbereich durch Endabschnitte des Lichtleitelements gebildet. Somit kann Licht direkt aus den Lichtleiterabschnitten in jeweils ein Ende des Lichtleitelements eingekoppelt werden, so dass das Lichtleitelement von zwei Seiten mit Licht gespeist ist.To a development of the invention are the first and / or the second Lichteinkoppelbereich by end portions of the light guide educated. Thus, light can come directly from the fiber optic sections in each one end of the light guide are coupled, so that the light guide is fed from two sides with light.
Besonders vorteilhaft ist es, wenn das Lichtleitelement emittierend ist. Hierdurch kann das Lichtleitelement in der erfindungsgemäßen platzsparenden und effizienten Weise mit Licht gespeist werden und kann somit ohne große Zugeständnisse an konstruktive Zwänge das Nachtdesign beispielsweise eines Kraftfahrzeugs optimieren.Especially It is advantageous if the light-guiding element is emitting. hereby can the light guide in the space-saving and efficient according to the invention Way with light can be fed and thus without much concessions to constructive constraints optimize the night design of a motor vehicle, for example.
Besonders vorteilhaft ist diese Wirkung, wenn das Lichtleitelement ringförmig ist. In diesem Fall kann beispielsweise die Kontur eines Scheinwerfers nachgezeichnet werden, was zu einem attraktiven Nachtdesign eines Kraftfahrzeugs beiträgt.Especially this effect is advantageous when the light-guiding element is annular. In this case, for example, the contour of a headlight be redrawn, resulting in an attractive night design of a Motor vehicle contributes.
Das Lichtleitelement kann aber auch stabförmig sein, beispielsweise um geradlinie Konturen eines Kraftfahrzeugbauteils nachzeichnen zu können.The But light guide can also be rod-shaped, for example to Trace straight contours of a motor vehicle component to can.
In vorteilhafter Weise umfasst die Lichtleiterstruktur mindestens eine Lichtquelle. Dabei können die Lichtleiterabschnitte jeweils von einer eigenen Lichtquelle gespeist werden, wodurch sich die in einen Lichtleiterabschnitt eingespeiste Lichtmenge individuell beeinflussen lässt.In Advantageously, the optical waveguide structure comprises at least one Light source. The can Each light guide sections fed by its own light source become, whereby the fed into a light guide section Can individually influence the amount of light.
Die Lichtleiterabschnitte können auch von einem gemeinsamen Laserlicht abgehen, der vorzugsweise von einer Lichtquelle gespeist ist. Diese Anordnung ermöglicht das gemeinsame Einspeisen von Licht in die Lichtleiterabschnitte und schließlich in das Lichtleitelement.The Fiber optic sections can also depart from a common laser light, preferably powered by a light source. This arrangement allows the common feeding of light into the light guide sections and after all in the light guide.
Die Lichtleiterstruktur kann abschnittsweise aus verschiedenen Materialien, insbesondere aus Glas und/oder Kunststoff gebildet sein, um entsprechenden Anforderungen an die Einbauverhältnisse, die Lichtleitfähigkeit und/oder die Dauerfestigkeit der Lichtleiterstruktur erfüllen zu können.The Fiber optic structure may be partially made of different materials, in particular be formed of glass and / or plastic to corresponding Requirements for the installation conditions, the photoconductivity and / or the fatigue strength of the optical fiber structure to meet can.
In der Lichtleiterstruktur kann auch mindestens ein Infrarotfilter integriert sein. Somit können Infrarotbestandteile eines eingespeisten Lichts gefiltert werden.In The light guide structure may also have at least one infrared filter be integrated. Thus, you can Infrared components of an input light to be filtered.
