Nachteilig an Linsen mit optisch nicht wirksamen Seitenflächen ist, dass in Abhängigkeit von dem Lichteinfallswinkel Totalreflexionen an der Seitenfläche auftreten, die zu einem unkontrollierbaren und gerichteten Lichtbündel führen, das zu einer unerwünschten Blendung führen kann.adversely on lenses with optically ineffective side surfaces is that depending from the angle of incidence total reflections on the side surface occur which lead to an uncontrollable and directed light beam, the to an undesirable Cause glare can.
Aufgabe der vorliegenden Erfindung ist es, eine Linse für einen Fahrzeugscheinwerfer sowie einen Fahrzeugscheinwerfer derart weiterzubilden, dass von Seitenflächen der Linse, die konstruktiv nicht zur Bildung einer vorgegebenen Lichtverteilung beitragen sollen, keine unerwünschten Blendwirkungen ausgehen.task The present invention is a lens for a vehicle headlight and further develop a vehicle headlight such that of faces the lens that constructively fails to form a given Contribute light distribution, no unwanted dazzling effects go out.
Zur Lösung dieser Aufgabe ist die erfindungsgemäße Linse in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass die Seitenfläche derart strukturiert ist, dass auf die Seitenfläche eintreffendes eingekoppeltes Licht an der Seitenfläche ausgekoppelt wird.to solution This object is the lens of the invention in conjunction with the preamble of claim 1, characterized in that the side surface is structured such that incident on the side surface incoupled light on the side surface is decoupled.
Zur Lösung dieser Aufgabe ist der Scheinwerfer für Fahrzeuge in Verbindung mit dem Oberbegriff des Patentanspruchs 9 dadurch gekennzeichnet, dass zwischen der Lichtquelle und der Lichteinkoppelfläche der Linse eine Abschatteinheit derart angeordnet ist, dass ein Anteil des Lichtes, der nach Eintritt in die Linse durch die Lichteinkoppelfläche auf die Seitenfläche derselben auftreffen würde, ausgeblendet wird.to solution This object is the headlight for vehicles in conjunction with the preamble of claim 9, characterized in that between the light source and the light coupling surface of the Lens a Abschatteinheit is arranged such that a proportion of the light entering the lens through the light input surface on the side surface the same would happen is hidden.
Der besondere Vorteil der Erfindung besteht darin, dass Mittel zur Vermeidung von Blendung vorgesehen sind, mittels derer eine unkontrollierbare Totalreflexion von Licht an einer Seitenfläche einer Linse und eine unerwünschte Blendung infolge der nachfolgenden Abstrahlung dieses Lichtanteils durch die Lichtauskoppelfläche verhindert wird. Vorteilhaft kann beispielsweise eine Abblendlichtverteilung bzw. eine Nebellichtverteilung erzeugt werden, wobei ein unerwünschter Blendlichtanteil infolge der Totalreflexion eines Lichtanteils an den Seitenflächen vermieden wird.Of the particular advantage of the invention is that means for avoidance are provided by glare, by means of which an uncontrollable Total reflection of light on a side surface of a lens and unwanted glare due to the subsequent radiation of this proportion of light through the light coupling is prevented. Advantageously, for example, a low beam distribution or a fog light distribution are generated, with an undesirable Glare component due to the total reflection of a light component the side surfaces is avoided.
Nach einer ersten Variante der Erfindung ist eine Seitenfläche einer Linse derart ausgebildet, dass der Anteil des eingekoppelten Lichtes, der auf die Seitenfläche trifft, an der Seitenfläche ausgekoppelt wird und somit nicht mehr zur vorgegebenen Lichtverteilung beitragen kann. Vorteilhaft wird hierdurch ein unerwünschter Anteil des in die Linse eingekoppelten Lichtes „ausgeblendet" und kann daher nicht durch die Lichtauskoppelfläche austreten.To A first variant of the invention is a side surface of a Lens formed such that the proportion of the injected light, the on the side surface meets, on the side surface is decoupled and thus no longer to the given light distribution can contribute. This advantageously becomes an undesirable one Proportion of the light coupled into the lens "hidden" and therefore can not through the light output surface escape.
Nach einer zweiten Variante der Erfindung kann zwischen der Linse und einer Halbleiterlichtquelle eine Abschatteinheit derart ausgebildet sein, so dass der Anteil des Lichtes, der bei Eintritt in die Linse auf eine Seitenfläche derselben treffen würde, absorbiert wird, das heißt an dem Eintritt in die Lichteinkoppelfläche in die Linse gehindert wird. Vorteilhaft kann hierdurch die Seitenfläche unbehandelt bzw. beliebig ausgebildet sein.To A second variant of the invention can be used between the lens and a shading unit is formed such a semiconductor light source so that the proportion of light entering upon the lens on a side surface same would be absorbed will, that is prevented from entering the light input surface into the lens becomes. As a result, the side surface can be untreated or arbitrary be educated.
Nach einer Weiterbildung der Erfindung kann die Seitenfläche der Linse eine Mehrzahl von Optikelementen aufweisen, so dass die auf die Seitenfläche von innen auftreffenden Lichtstrahlen gezielt durch die Seitenfläche nach außen ausgekoppelt werden. Vorteilhaft kann hierdurch eine sichere Auskopplung der unerwünschten Lichtstrahlen an der Seitenfläche erfolgen.To a development of the invention, the side surface of Lens have a plurality of optical elements, so that on the side surface of inside light rays targeted by the side surface Outside be decoupled. This can advantageously be a reliable coupling of the undesirable Light rays take place on the side surface.
Nach einer Weiterbildung der Erfindung der Erfindung ist der Seitenfläche der Linse einer Lichtabsorbereinheit zugeordnet, in der das mittels der Seitenfläche ausgekoppelte Licht aufgenommen wird. Vorzugsweise ist die Absorbereinheit einstückig mit einem Halter der Linse bzw. einem die Lichtquellen und die Linse tragenden Halter verbunden. Auf diese Weise wird verhindert, dass benachbarte Linsen nicht mit dem von den Seitenflächen ausgekoppelten Licht beaufschlagt werden.According to a development of the invention of the invention, the side surface of the lens is a light associated absorber unit, in which the decoupled by the side surface light is absorbed. Preferably, the absorber unit is integrally connected to a holder of the lens or a holder carrying the light sources and the lens. In this way it is prevented that adjacent lenses are not acted upon by the light coupled out from the side surfaces.
Nach einer Weiterbildung der Erfindung kann der Seitenfläche der Linse eine Lichtverteilungseinheit zugeordnet sein, mittels derer ein die vorgegebene Lichtverteilung unterstützendes Ergänzungslichtbündel oder ein Lichtbündel für eine gesonderte Lichtfunktion erzeugt wird. Vorteilhaft kann auf diese Weise die Lichtausbeute erhöht werden.To a development of the invention, the side surface of the Lens be associated with a light distribution unit, by means of which a supplemental light bundle supporting the given light distribution or a ray of light for one separate light function is generated. Can be beneficial in this way the light output increases become.
