Abstract
Lichtleiterstruktur (42) zur Verwendung in Kraftfahrzeugen, bei der ein erster Lichtleitweg (60) gebildet ist durch einen ersten Lichtleiterabschnitt (44), der mit einem ersten Lichteinkoppelbereich (52) eines Lichtleitelements (56) verbunden ist, und bei der mindestens ein zweiter Lichtleitweg (62) gebildet ist durch einen zweiten Lichtleiterabschnitt (46), der mit einem zweiten Lichteinkoppelbereich (54) des Lichtleitelements (56) verbunden ist, wobei das Lichtleitelement (56) lichtemittierend ist und der Kontur eines Kraftfahrzeugscheinwerfers entspricht, dadurch gekennzeichnet, dass die Lichtleiterabschnitte (44, 46) sich gegenseitig kreuzend durchdringen.A fiber optic structure (42) for use in automobiles, wherein a first optical fiber path (60) is formed by a first optical fiber portion (44) connected to a first light input region (52) of a light guide member (56) and at least one second optical fiber path (62) is formed by a second light guide section (46) which is connected to a second Lichteinkoppelbereich (54) of the light guide element (56), wherein the light guide element (56) is light emitting and corresponds to the contour of a motor vehicle headlamp, characterized in that the light guide sections (44, 46) interpenetrate each other.
Description
Die Erfindung betrifft eine Lichtleiterstruktur nach dem Oberbegriff des Anspruchs 1. Eine derartige Lichtleiterstruktur ist zum Beispiel aus der Druckschrift
Solche Lichtleiterstrukturen werden bei Kraftfahrzeugen verwendet, um ein ansprechendes Nachtdesign zu schaffen.Such fiber optic structures are used in motor vehicles 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-guiding element is fed according to the prior art by optical waveguide sections which open at light-coupling regions of the light-guiding element.
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 light guide structures have the disadvantage that they are limited adaptable to cramped installation conditions, as they are given above all in motor vehicles. This is also due to the fact that the light guide sections or light guide elements must not have narrow radii, since these are associated with 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.Based on this, the present invention has the object to provide a light guide structure, with an efficient and space-saving coupling of light in a light guide is possible.
Diese Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in claim 1.
Diese Lichtleiterstruktur ermöglicht eine besonders kompakte Konstruktion.This light guide structure allows a particularly compact design.
Wenn die Achsen der Lichtleiterabschnitte im Bereich der sich durchdringenden Lichtleitwege zwischen sich einen Winkel von größer als 0° und ≤ 90° bilden, ist besonders gut gewährleistet, dass die Lichtverluste gering gehalten sind.If the axes of the light guide sections form an angle of greater than 0 ° and ≦ 90 ° between them in the region of the penetrating optical paths, it 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. 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.According to a development of the invention, the first and / or the second Lichteinkoppelbereich are formed by end portions of the light guide. Thus, light can be coupled directly from the light guide sections in each case one end of the light guide, so that the light guide is fed from two sides with light.
Das Lichtleitelement ist emittierend. 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.The light-guiding element is emitting. In this way, the light-guiding element can be fed with light in the space-saving and efficient manner according to the invention and can thus optimize the night design of, for example, a motor vehicle without making major concessions to constructive constraints.
Ein Nachzeichnen der Kontur eines Scheinwerfers trägt zu einem attraktiven Nachtdesign eines Kraftfahrzeugs bei.Tracing the contour of a headlamp contributes to an attractive night design of a motor vehicle.
Das Lichtleitelement kann ringförmig sein.The light-guiding element can be annular.
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.Advantageously, the light guide structure comprises at least one light source. In this case, the light guide sections can each be fed by a separate light source, whereby the amount of light fed into a light guide section can be influenced individually.
Die Lichtleiterabschnitte können auch von einem gemeinsamen Laserlicht abgehen, das vorzugsweise von einer Lichtquelle gespeist ist. Diese Anordnung ermöglicht das gemeinsame Einspeisen von Licht in die Lichtleiterabschnitte und schließlich in das Lichtleitelement.The light guide sections can also depart from a common laser light, which is preferably fed by a light source. This arrangement allows the common feeding of light into the light guide sections and finally into 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 light guide structure may be formed in sections of different materials, in particular of glass and / or plastic, in order to meet appropriate requirements for the installation conditions, the light conductivity and / or the fatigue strength of the light guide structure.
In der Lichtleiterstruktur kann auch mindestens ein Infrarotfilter integriert sein. Somit können Infrarotbestandteile eines eingespeisten Lichts gefiltert werden.In the light guide structure and at least one infrared filter can be integrated. Thus, infrared components of an input light can be filtered.
Weitere Vorteile und vorteilhafte Ausgestaltungen der Erfindung sind der nachfolgenden Zeichnung, deren Beschreibung und den Patentansprüchen entnehmbar. Alle in der Zeichnung, deren Beschreibung und den Patentansprüchen beschriebenen Merkmale können sowohl einzeln als auch in beliebiger Kombination miteinander erfindungswesentlich sein.Further advantages and advantageous embodiments of the invention are the following drawings, the description and the claims removable. All features described in the drawing, the description and the claims may be essential to the invention both individually and in any combination.
