Abstract
Description
Die Erfindung betrifft eine Lichtleiteranordnung gemäß dem Oberbegriff von Anspruch 1.The The invention relates to an optical fiber arrangement according to the preamble of claim 1.
Eine
solche Lichtleiteranordnung für
eine zum Einbau in den Außen-Rückblickspiegel
eines Fahrzeugs bestimmte Seitenblinkleuchte ist beispielsweise
aus der Druckschrift
Da die Seitenkante, in welche das Licht der Lichtquellenanordnung eingespeist wird, eine im Vergleich zur Dicke des plattenförmigen Lichtleiters große Länge besitzt, ist es erforderlich, dass die Lichtquellenanordnung mehrere längs dieser Seitenkante angeordnete Lichtquellen umfasst, die vorzugsweise von Leuchtdioden gebildet werden. Somit tritt aus jedem von mehreren streifenförmigen, in der Einbaulage der Fahrzeugleuchte vertikal übereinander liegenden Bereichen des plattenförmigen Lichtleiters im wesentlichen das Licht immer nur einer Lichtquelle aus. Da diese Lichtquellen unterschiedlich rasch altern können und sich damit die Helligkeit des von ihnen abgegebenen Lichts unterschiedlich stark verringert, kann es zu einer ungleichförmigen Ausleuchtung der vorderen Hauptfläche des plattenförmigen Lichtleiters kommen, wodurch zumindest das ästhetische Erscheinungsbild einer solchen Fahrzeugleuchte beeinträchtigt wird.There the side edge into which the light of the light source arrangement is fed is, has a long compared to the thickness of the plate-shaped light guide, It is necessary that the light source arrangement more along this Side edge arranged light sources, preferably from Light emitting diodes are formed. Thus, each one comes out of several striped, in the installation position of the vehicle lamp vertically superimposed areas of the plate-shaped Light guide essentially the light from only one light source. Since these light sources can age at different rates and Thus, the brightness of the light emitted by them differs greatly reduced, it may cause a non-uniform illumination of the front main area the plate-shaped light guide come, at least the aesthetic Appearance of such a vehicle lamp is impaired.
Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine Lichtleiteranordnung der oben genannten Art so weiterzubilden, dass die Ausleuchtung der nach außen weisenden Hauptfläche eines solchen plattenförmigen Lichtleiters einzig und allein durch die Geometrie der Lichtleiteranordnung bestimmt wird und insbesondere von Alterungserscheinungen der Lichtquelle unabhängig ist.In contrast, lies The invention is based on the object, a light guide arrangement of educate the above-mentioned type so that the illumination of the outward pointing main surface such a plate-shaped Optical fiber solely by the geometry of the light guide assembly is determined and in particular of aging of the light source independently is.
Zur Lösung dieser Aufgabe sieht die Erfindung die im Anspruch 1 niedergelegten Merkmale vor.to solution This object is achieved by the invention laid down in claim 1 Features before.
Dadurch, dass gemäß der Erfindung das von einer einzigen Lichtquelle, beispielsweise einer sehr hellen, heute kommerziell ohne weiteres erhältlichen Leuchtdiode abgegebene Licht zunächst in einen zusätzlich zu dem plattenförmigen Lichtleiter vorgesehenen, lang gestreckten Lichtleitstab eingespeist und von diesem parallel zu einer der Längskanten des plattenförmigen Lichtleiters verteilt wird, um nach und nach in den plattenförmigen Lichtleiter übergekoppelt zu werden, kann letzterer mit einer lediglich durch die Geometrie der Anordnung vorgegebenen Intensitätsverteilung, beispielsweise einer sehr gleichmäßigen oder aber auch jeder anderen gewünschten Intensitätsverteilung ausgeleuchtet werden. Entscheidend ist, dass die Intensitätsverteilung unabhängig von der Helligkeit der einzigen Lichtquelle, insbesondere also auch von deren Alterungserscheinungen ist und daher in der einmal vorgegebenen Weise immer gleich bleibt.Thereby, that according to the invention that from a single light source, such as a very bright, today commercially available readily available light emitting diode Light first in an additional to the plate-shaped Fiber optics provided, elongated light guide rod fed and from this parallel to one of the longitudinal edges of the plate-shaped light guide is gradually distributed over to the plate-shaped light guide to can be, the latter with only by the geometry of the Arrangement predetermined intensity distribution, for example, a very even or everyone other desired intensity distribution be lit up. What matters is that the intensity distribution independently from the brightness of the single light source, especially so too whose aging phenomena is and therefore in the once predetermined Way always stays the same.
Vorzugsweise sind der plattenförmige Lichtleiter und der Lichtleitstab aus dem gleichen Material hergestellt und einstückig miteinander verbunden, so dass die erfindungsgemäße Lichtleiteranordnung sehr kostengünstig im Spritzgussverfahren hergestellt werden kann.Preferably are the plate-shaped Light guide and the light guide rod made of the same material and in one piece interconnected, so that the light guide assembly according to the invention very economical can be produced by injection molding.
Um zu verhindern, dass aus dem Lichtleitstab austretendes Streulicht, das zunächst nicht in den plattenförmigen Lichtleiter gelangt, für dessen Ausleuchtung verloren geht, ist der Lichtleitstab auf seinen vom plattenförmigen Lichtleiter abgewandten Seiten gemäß einer bevorzugten Ausführungsform zumindest teilweise von einer sich im wesentlichen über seine gesamte Länge erstreckenden Reflektoranordnung umgeben, die besagtes Streulicht so reflektiert, dass es ebenfalls in den plattenförmigen Lichtleiter gelangt.Around to prevent stray light emerging from the light guide rod, the first not in the plate-shaped Optical fiber passes, for whose illumination is lost, is the light guide rod on his from the plate-shaped Light guides facing away from sides according to a preferred embodiment, at least partially extending from one substantially over its entire length Surrounded by a reflector arrangement which reflects said scattered light in such a way that that it also enters the plate-shaped light guide.
Diese und weitere vorteilhafte Ausführungsformen einer erfindungsgemäßen Lichtleiteranordnung sind in den Unteransprüchen niedergelegt.These and further advantageous embodiments a light guide arrangement according to the invention are in the subclaims resigned.
