Ausgehend von dem geschilderten Stand der Technik ist es die Aufgabe der vorliegenden Erfindung, eine Scheinwerfereinrichtung für Kraftfahrzeuge weiterzubilden, welche in der Lage ist, unterschiedliche Lichtteile mehreren Lichtauskoppelelementen entweder gleichzeitig oder getrennt zur Verfügung zu stellen.outgoing From the described prior art, it is the object of the present Invention to develop a headlamp device for motor vehicles, which is capable of different light parts of a plurality of light output elements either simultaneously or separately.
Gelöst wird diese Aufgabe mit den Merkmalen des Patentanspruchs 1.Is solved This object with the features of claim 1.
Dabei ist vorgesehen, dass das Mittel zum Lenken zumindest von Anteilen des von der Lichtquelle emittierten Lichts auf eine Lichteinkoppelungsfläche des zweiten Lichtleiters, wobei das Mittel durch einen Strahlteiler oder auch sogenannten Beamsplitter gebildet ist, der in den Strahlengang des Lichtbündels hinein bewegt werden kann. Sofern der Strahlteiler oder Beamsplitter außerhalb des Strahlengangs befindlich ist, wird sämtliches durch den Reflektor reflektiertes Licht auf die Lichteinkoppelungsfläche des ersten Lichtleiters gelenkt. Wird dann der Strahlteiler in den Strahlengang bewegt, so wird ein Teil des Lichtes mittels Transmission durch den Strahlteiler hindurchtreten und weiterhin auf die Lichteinkoppelfläche des ersten Lichtleiters auftreffen. Ein zweiter Anteil des Lichts wird durch den Strahlteiler reflektiert und wird auf die Lichteinkoppelfläche des zweiten Lichtleiters gelenkt.there It is envisaged that the means of directing at least shares of the light emitted from the light source onto a light coupling surface of the light source second light guide, wherein the means by a beam splitter or so-called beam splitter is formed in the beam path of the light beam can be moved into it. Unless the beam splitter or beam splitter outside the beam path is located, is all through the reflector reflected light on the Lichteinkoppelungsfläche the first light guide directed. If then the beam splitter is moved into the beam path, so a part of the light is transmitted through the beam splitter pass through and continue on the light coupling surface of the first light guide. A second portion of the light is is reflected by the beam splitter and is incident on the light input surface of the directed second optical fiber.
Eine derartige Gestaltung, bei der durch die in den Strahlengang bewegbare Vorsehung eines Beamsplitters der Lichtstrahl entweder aufgeteilt oder vollständig auf einen Lichtleiter bzw. mehrere Lichtleiter geleitet werden kann, besitzt den Vorteil, dass mehrere Lichtleiter entweder gleichzeitig oder getrennt voneinander angesteuert werden können bzw. mit Licht versorgt werden können, wobei nur eine Lichtquelle innerhalb der Scheinwerfereinrichtung vorgesehen werden muss.A Such a design, in which by the movable in the beam path Providence of a beam splitter the beam either split or Completely can be directed to a light guide or a plurality of light guides, has the advantage that several light guides either simultaneously or can be controlled separately or supplied with light can be wherein only one light source within the headlamp device must be provided.
Dabei führt in einer Ausführungsform der erste Lichtleiter zu einem Lichtauskoppelelement, das als transparentes Zwischenstück ausgebildet ist, und als Lichtleiterabschlusskörper dient. Dieser Lichtleiterabschlusskörper wird dann durch eine Linse, die ihm nachgeschaltet ist, abgebildet. Dabei kann vorgesehen sein, dass der erste Lichtleiter zur Erzeugung eines Abblendlichtes dient und der zweite Lichtleiter, der zu einem zweiten Lichtleiterabschlusskörper führt und durch eine zweite Linse abgebildet wird, eine Fernlichtverteilung abstrahlt. Dabei ist vorgesehen, dass der Strahlteiler insbesondere nicht wellenselektiv arbeitet, wie es im Stand der Technik bekannt war, um die Infrarotlichtanteile aus dem sichtbaren Licht abzuspalten für eine Nachtsichteinrichtung, sondern wellenlängenunselektiv arbeitet, indem er so gestaltet ist, dass er einen Anteil des Lichts passieren lässt und einen Anteil des Lichts reflektiert, wobei sämtliche spektralen Bereiche gleichmäßig reflektiert bzw. transmittiert werden können. Dies kann beispielsweise vorgesehen werden, indem der Strahlteiler mit einer entsprechenden Beschichtung versehen ist, die zum Teil eine Transmission und zum Teil eine Reflexion zulässt. Derartige teiltransparente Spiegel mit verschiedenen Reflexions- und Transmissionsgraden sind im Stand der Technik bekannt.there leads in an embodiment the first light guide to a light extraction element, which is transparent connecting piece is formed, and serves as a light guide end body. This light guide end body is then imaged by a lens that is downstream of him. there can be provided that the first optical fiber for generating a Abblendlichtes serves and the second light guide, which leads to a second Optical fiber termination body leads and is imaged by a second lens, a high beam distribution radiates. It is provided that the beam splitter in particular not wave selective, as known in the art was to split off the infrared light components from the visible light for one Night vision device, but wavelength-selective works by it is designed to let a portion of the light pass through and reflects a portion of the light, with all spectral ranges evenly reflected or can be transmitted. This can be provided, for example, by the beam splitter provided with an appropriate coating, in part a transmission and partly allows a reflection. such semi-transparent mirrors with different reflectance and transmittance levels are known in the art.
Dabei kann sowohl vorgesehen sein, dass der Strahlteiler in den Strahlengang durch eine translatorische Bewegung verschiebbar ist oder er kann rotatorisch in den Strahlengang hineingeschwenkt werden.there can be provided both that the beam splitter in the beam path can be displaced by a translational movement or it can be rotational be pivoted into the beam path.
Grundsätzlich ist es auch möglich, verschiedene Spiegel mit verschiedenen Reflexions- und Transmissionsgraden vorzusehen, wobei je nach gewünschter Lichtverteilung verschiedene teiltransparente Spiegel gemeinsam oder unterschiedliche teiltransparente Spiegel in den Strahlengang eingeschoben werden können.Basically it also possible different mirrors with different reflection and transmission levels provide, depending on the desired Light distribution different semi-transparent mirrors together or different partially transparent mirrors in the beam path can be inserted.
Auf diese Weise kann die Lichtcharakteristik, insbesondere die Aufteilung zwischen Abblend- und Fernlicht weiter individualisiert werden.On This way, the light characteristic, in particular the distribution be further individualized between dipped and main beam.
Des Weiteren kann auch vorgesehen sein, dass mehr als zwei Lichtleiter, die zu mehr als zwei Lichtauskoppelelementen führen, vorgesehen sind, wobei insbesondere vorgesehen sein kann, dass beispielsweise der erste Lichtleiter sich nach seiner Lichteinkoppelfläche aufteilt und das Licht zu zwei separaten Lichtauskopplungselementen weiterleitet.Of Furthermore, it can also be provided that more than two optical fibers, which lead to more than two light output elements are provided, wherein In particular, it may be provided that, for example, the first Optical fiber is divided according to its light input surface and the light to two separate light extraction elements forwards.
So können beispielsweise zwei Lichtauskoppelelemente einer Lichtfunktion, wie beispielsweise dem Abblendlicht, zugeordnet sein.So can For example, two light output elements of a light function, such as the low beam, be assigned.
