Description
Die Erfindung betrifft Leuchte für Fahrzeuge, insbesondere für Kraftfahrzeuge, mit einem Lichtleitelement enthaltend eine auf einer Vorderseite desselben angeordnete Lichtaustrittsfläche, eine Lichteinkoppelfläche, an der das von der Lichtquelle emittierte Lichtbündel eingekoppelt wird, eine Seitenfläche, an der zumindest ein Teil des eingekoppelten Lichtbündels totalreflektiert und dann in Lichtabstrahlrichtung an eine Lichtaustrittsfläche weitergeleitet wird und mit mindestens einer dem Lichtleitelement zugeordneten Leuchtdiode.The invention relates to lights for vehicles, in particular for motor vehicles, with a light guide element containing one on a front the same arranged light exit surface, a light coupling surface which couples the light beam emitted by the light source, a Side surface where at least part of the coupled light beam is totally reflected and then forwarded in the direction of light emission to a light exit surface and with at least one assigned to the light guide element Led.

Aufgabe der vorliegenden Erfindung ist es daher, eine Leuchte für Fahrzeuge mit einer Mehrzahl von Leuchtdioden als Lichtquelle derart weiterzubilden, dass das Erscheinungsbild der Leuchte mit Leuchtdioden als Lichtquellen dem Erscheinungsbild einer Leuchte mit einer Gasentladungslampe als Lichtquelle angenähert wird.Object of the present invention is therefore a lamp for Vehicles with a plurality of light emitting diodes as a light source further that the appearance of the lamp with light emitting diodes as light sources the appearance of a lamp with a gas discharge lamp approximated as a light source becomes.
Zur Lösung dieser Aufgabe ist die erfindungsgemäße Leuchte in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass die Leuchtdioden entlang einer Reihe angeordnet sind, an der sich in Lichtabstrahlrichtung ein langgestrecktes Lichtleitelement anschließt, wobei das Lichtleitelement in einem Scheitelbereich eines rinnenförmigen Reflektors angeordnet ist.To solve this problem is the lamp according to the invention in connection with the preamble of claim 1 thereby characterized in that the LEDs are arranged along a row are at which there is an elongated light-guiding element in the direction of light emission connects, wherein the light guide element in an apex area of a trough-shaped reflector is arranged.
Der besondere Vorteil der Erfindung besteht darin, dass die Leuchtdioden für einen äußeren Betrachter in keinem Betrachtungswinkel sichtbar sind. Grundgedanke der Erfindung ist es, das Lichtleitelement derart anzuordnen, dass die Leuchtdioden für einen äußeren Betrachter vollständig verdeckt sind. Durch die erfindungsgemäße Anordnung des Lichtleitelementes in einem Scheitelbereich eines rinnenförmigen Reflektors kann eine vollständige Verdeckung der Leuchtdioden erzielt werden, ohne dass Einbußen hinsichtlich der Lichtausbeute hinzunehmen wären.The particular advantage of the invention is that the light emitting diodes for an outside viewer in none Viewing angles are visible. The basic idea of the invention is it to arrange the light guide such that the light emitting diodes for an outside viewer Completely are covered. Due to the arrangement of the light guide element according to the invention in an apex area of a trough-shaped reflector full Hiding the LEDs can be achieved without sacrificing the light output would have to be accepted.
Nach einer bevorzugten Ausführungsform der Erfindung ist die Vorderseite des Lichtleitelementes derart ausgebildet, dass das in das Lichtleitelement eingespeiste Lichtbündel entsprechend einer Gasentladungslampe von dem Lichtleitelement abgestrahlt wird. Hierdurch bildet das Lichtleitelement eine Gasentladungslampe nach, dass heißt die Abstrahlcharakteristik des Lichtleitelementes stimmt im wesentlichen mit der Abstrahlcharakteristik einer Gasentladungslampe überein. Vorteilhaft kann im Unterschied zu der Gasentladungslampe die horizontale Lichtabstrahlung entlang der Längserstreckung der Leuchte begrenzt werden. Somit können die gesetzlichen Anforderungen für Signalleuchten an Kraftfahrzeugen bezüglich der einzuhaltenden Maximalwerte auf seitlichen Messpunkten leichter erfüllt werden.According to a preferred embodiment of the invention, the front of the light-guiding element is designed in such a way that the light beam fed into the light-guiding element is emitted by the light-guiding element in accordance with a gas discharge lamp. As a result, the light-guiding element simulates a gas discharge lamp, that is to say the emission characteristic of the light-guiding element essentially corresponds to the emission characteristic of a gas discharge lamp. In contrast to the gas discharge lamp, the horizontal light radiation along the longitudinal extension of the lamp can advantageously be limited. This means that the legal requirements for signal lights on motor vehicles with regard to those to be complied with Maximum values on lateral measuring points can be more easily met.
Nach einer Weiterbildung der Erfindung ist die Vorderseite des Lichtleitelementes als eine in Längsrichtung verlaufende Mulde ausgebildet, so dass ein erstes auf eine Seitenfläche der Mulde auftreffendes Lichtbündel quer zur Längsmittelebene des Lichtleitelementes totalreflektiert wird in Richtung einer Reflektorfläche. Ein weiteres zweites Teillichtbündel wird von der Vorderseite in Lichtabstrahlrichtung ausgekoppelt, so dass eine Lichtablenkung in einem relativ großen Winkelbereich gewährleistet ist. Es wird somit weitgehend die Lichtfunktion einer Gasentladungslampe nachgebildet.After a further development of the invention is the front of the light guide as one in the longitudinal direction extending trough formed so that a first on a side surface of the Hollow beam of light hitting transverse to the median longitudinal plane of the Light guide element is totally reflected in the direction of a reflector surface. On another second partial light beam is coupled out from the front in the direction of light emission, so that a light deflection in a relatively large angular range is guaranteed is. It largely becomes the light function of a gas discharge lamp simulated.
Nach einer Weiterbildung der Erfindung können gegenüberliegende Muldenflächen eben, konkav- oder konvexförmig ausgebildet sein, um eine steile seitliche Lichtabstrahlung zu ermöglichen. Eine zwischen den Muldenflächen angeordnete Zentralfläche der Mulde bewirkt, dass stets ein nach vorne gerichtetes Teillichtbündel abgestrahlt wird.After a further development of the invention can opposing trough surfaces flat, concave or convex be designed to allow a steep lateral light emission. One between the trough surfaces arranged central area the trough ensures that a partial light beam directed towards the front is always emitted becomes.
Nach einer Weiterbildung der Erfindung kann die Seitenfläche des Lichtleitelementes auch derart ausgebildet sein, dass die Leuchtdiode mit einer quer zur Lichtabstrahlrichtung angeordneten optischen Achse angeordnet sind. Hierbei bildet eine langgestreckte Seitenfläche eine Umlenkfläche zum Umlenken eines Teil des eingekoppelten Lichtbündels.After a further development of the invention can the side surface of the light-guiding element can also be designed such that the light-emitting diode with an optical axis arranged transversely to the direction of light emission are arranged. Here, an elongated side surface forms a deflection to redirect part of the coupled light beam.
Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further advantages of the invention result itself from the further subclaims.
