Description

Die vorliegende Erfindung betrifft ein Scheinwerfersystem für ein Fahrzeug mit einer Lichtquelle, einer Öffnung, durch welche das von der Lichtquelle emittierte Licht zur Bereitstellung einer ersten Lichtfunktion durchtritt, und einer ersten Einrichtung, mittels welcher zumindest ein Teil des von der Lichtquelle emittierten Lichts zur Bereitstellung einer zweiten Lichtfunktion umlenkbar und auskoppelbar ist.The present invention relates to a headlamp system for a vehicle having a light source, an opening through which the light emitted by the light source passes to provide a first light function, and a first device, by means of which at least a part of the light emitted by the light source to provide a second light function can be deflected and decoupled.

Im Kraftfahrzeugbereich haben sich vielfältige Scheinwerfersysteme für unterschiedliche Anwendungsfälle, wie z. B. für Abblend-, Fern- und Tagfahrlicht mit unterschiedlichen Lichtquellen etabliert. Als Lichtquellen wurden für die unterschiedlichen Anwendungsfälle Glühlampen, Halogenlampen, Gasentladungslampen und LEDs verwendet. Bei der Neugestaltung von Fahrzeugen ergibt sich vielfach das Problem, dass aus aerodynamischen und gestalterischen Gründen der Bauraum, welcher für Leuchtenanordnungen bereitgestellt wird, sehr begrenzt ist. Dies muss bei der Gestaltung der neuer Scheinwerfersysteme berücksichtigt werden. Es ist daher vorteilhaft verschiedene Lichtfunktionen in einem Scheinwerfermodul zu integrieren und dabei ggf. auch nur eine einzige Lichtquelle für unterschiedliche Lichtfunktionen einzusetzen.In the automotive field, have a variety of headlamp systems for different applications, such. B. established for low beam, long-distance and daytime running lights with different light sources. As light sources incandescent lamps, halogen lamps, gas discharge lamps and LEDs were used for the different applications. In the redesign of vehicles often results in the problem that for aerodynamic and design reasons, the space that is provided for lighting arrangements, is very limited. This must be taken into account when designing the new headlamp systems. It is therefore advantageous to integrate different light functions in a headlight module and possibly even use only a single light source for different light functions.

Die DE 10 2005 023 817 A1 beschreibt beispielsweise einen Fahrzeugscheinwerfer mit einer Lichtquelle, deren Lichtemission für zwei Lichtfunktionen nutzbar ist. Für die zweite Lichtfunktion wird ein schwenkbarer Spiegel in die Hauptabstrahlungsrichtung für die erste Lichtfunktion gebracht. Dieser Spiegel kann das Licht der ersten Lichtfunktion teilweise so umlenken, dass das Licht in ein Lichtleitelement eingekoppelt und an einem beliebigen Ort als zweite Lichtfunktion ausgekoppelt wird.The DE 10 2005 023 817 A1 describes, for example, a vehicle headlamp with a light source whose light emission can be used for two light functions. For the second light function, a pivotable mirror is brought into the main emission direction for the first light function. This mirror can deflect the light of the first light function partly so that the light is coupled into a light guide and coupled out at any location as a second light function.

Die DE 100 03 061 A1 beschreibt ein Beleuchtungssystem für Kraftfahrzeuge mit einer Tagessignallichtfunktion, wobei ein Scheinwerfer mit nur einer Entladungslampe, einem Reflektor und einer in Hauptabstrahlrichtung liegenden verstellbaren Blende benutzt wird.The DE 100 03 061 A1 describes a lighting system for motor vehicles with a daytime signal light function, wherein a headlamp is used with only one discharge lamp, a reflector and a lying in the main emission adjustable diaphragm.

Die DE 195 26 023 A1 beschreibt einen Scheinwerfer zum Erzeugen definierter Hell/Dunkel-Grenzen für ein asymmetrisches Abblendlicht, wobei Blenden und Reflexionsmittel zum Einsatz kommen. Weiterhin beschreibt die Druckschrift Möglichkeiten zur Nutzung weiterer Lichtfunktionen bei Verwendung von nur einer Lichtquelle.The DE 195 26 023 A1 describes a headlamp for generating defined bright / dark boundaries for an asymmetrical low beam, with aperture and reflection means be used. Furthermore, the document describes possibilities for using further light functions when using only one light source.

Es ist die Aufgabe der vorliegenden Erfindung ein Scheinwerfersystem der eingangs genannten Art so weiterzubilden, dass zumindest zwei Lichtfunktionen mit nur einer Lichtquelle bereitgestellt werden können, wobei der Aufbau des Scheinwerfersystems flexibel an verschiedene Bauraumverhältnisse angepasst werden kann.It is the object of the present invention to develop a headlamp system of the type mentioned above such that at least two light functions can be provided with only one light source, wherein the structure of the headlamp system can be flexibly adapted to different space conditions.

Erfindungsgemäß wird diese Aufgabe durch ein Scheinwerfersystem mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Aus- und Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.According to the invention this object is achieved by a headlamp system with the features of claim 1. Advantageous training and further developments emerge from the dependent claims.

Das erfindungsgemäße Scheinwerfersystem ist durch eine zweite Einrichtung, mit welcher die Öffnung für die erste Lichtfunktion optisch verschließbar ist, gekennzeichnet, wobei das von der Lichtquelle emittierte und auf die zweite Einrichtung auftreffende Licht nicht zur Bereitstellung der zweiten Lichtfunktion auskoppelbar ist. Die zweite Einrichtung ist insbesondere separat von der ersten Einrichtung vorgesehen.The headlamp system according to the invention is characterized by a second device, with which the opening for the first light function is optically closed, wherein the light emitted from the light source and incident on the second device light can not be coupled out to provide the second light function. The second device is provided in particular separately from the first device.

Vorteilhafterweise lässt sich das erfindungsgemäße Scheinwerfersystem sehr flexibel an verschiedene Bauraumverhältnisse anpassen, da die erste Einrichtung zum Umlenken und Auskoppeln des Lichts für die zweite Lichtfunktion unabhängig von der zweiten Einrichtung zum Verschließen der Öffnung für die erste Lichtfunktion ausgebildet und angeordnet werden kann. Ferner können bei dem erfindungsgemäßen Scheinwerfersystem mehrere Lichtfunktionen flexibler bereitgestellt werden. Wenn nämlich, wie im einleitend genannten Stand der Technik, durch eine Einrichtung gleichzeitig der Strahlengang für eine Lichtfunktion zumindest teilweise verschlossen und Licht für eine andere Lichtfunktion ausgekoppelt wird, können beide Lichtfunktionen nicht unabhängig voneinander betrieben werden. Wenn jedoch, wie bei dem erfindungsgemäßen Scheinwerfersystem, der Strahlengang für die eine Lichtfunktion unabhängig von der Lichtauskopplung für die andere Lichtfunktion verschlossen oder geöffnet werden kann, können beide Lichtfunktionen unabhängig voneinander sowohl getrennt als auch gemeinsam betrieben werden.Advantageously, the headlamp system according to the invention can be adapted very flexibly to different space conditions, since the first means for deflecting and decoupling the light for the second light function can be formed and arranged independently of the second means for closing the opening for the first light function. Furthermore, in the headlamp system according to the invention, a plurality of light functions can be provided more flexibly. Namely, if, as in the introductory cited prior art, by a device at the same time the beam path for a light function at least partially closed and coupled out light for another light function, both light functions can not be operated independently. However, if, as in the headlight system according to the invention, the beam path for the one light function can be closed or opened independently of the light extraction for the other light function, both light functions can be operated independently of each other both separately and together.

Gemäß einer weiteren Ausführung des Scheinwerfersystems umfasst die zweite Einrichtung eine schwenkbare oder verschiebbare Blende. Vorteilhafterweise kann durch diese Ausführung die Auswahl des Einbauraums flexibel gewählt werden, da die Blende von verschiedenen Seiten vor die Öffnung bewegt werden kann.According to a further embodiment of the headlamp system, the second device comprises a pivotable or displaceable diaphragm. Advantageously, the selection of the installation space can be chosen flexibly by this design, since the aperture can be moved from different sides in front of the opening.

Gemäß einer weiteren Ausführung des Scheinwerfersystems umfasst die erste Einrichtung zumindest einen Reflektor. Vorteilhaft an der Verwendung eines Reflektors ist, dass er kostengünstig und robust genug für den Einsatz im Kraftfahrzeug ist.According to a further embodiment of the headlight system, the first device comprises at least one reflector. An advantage of the use of a reflector is that it is inexpensive and robust enough for use in motor vehicles.

Gemäß einer weiteren Ausführung des Scheinwerfersystems ist der Reflektor für die Lichtauskopplung der Lichtemission der Lichtquelle für die zweite Lichtfunktion schwenkbar oder verschiebbar, wobei in einer ersten Position von der Lichtquelle emittiertes Licht von dem Reflektor reflektiert wird und der Reflektor sich in einer zweiten Position nicht im Strahlengang des von der Lichtquelle emittierten Lichts befindet. Vorteilhafterweise beeinflusst der Reflektor in der zweiten Position die erste Lichtfunktion nicht, während der Reflektor in der ersten Position zielgerichtet das Licht auskoppeln kann.According to a further embodiment of the headlamp system, the reflector for the light outcoupling of the light emission of the light source for the second light function is pivotable or displaceable, wherein light emitted by the light source is reflected by the reflector in a first position and the reflector is not in the beam path in a second position the light emitted by the light source is located. Advantageously, the reflector does not influence the first light function in the second position, while the reflector in the first position can purposefully decouple the light.

Gemäß einer weiteren Ausführung ist zur Umlenkung des ausgekoppelten Lichts zumindest ein weiterer Reflektor vorgesehen. Vorteilhafterweise kann das Licht auf diese Weise um Verbauungen herum geführt werden, um letztendlich an einem gewünschten Ort abgestrahlt zu werden.According to a further embodiment, at least one further reflector is provided for deflecting the decoupled light. Advantageously, the light can be passed around constructions in this way, in order ultimately to be radiated at a desired location.

Gemäß einer weiteren Ausführung des Scheinwerfersystems kann die erste Einrichtung zumindest einen Lichtleiter umfassen. Vorteilhafterweise kann auf diese Weise das ausgekoppelte Licht sehr einfach und flexibel über schwer zugängliche Einbauräume und größere Entfernungen geleitet werden.According to a further embodiment of the headlamp system, the first device may comprise at least one light guide. Advantageously, in this way the coupled-out light can be conducted in a very simple and flexible manner over installation spaces which are difficult to access and greater distances.

Gemäß einer weiteren Ausführung des Scheinwerfersystems kann der Lichtleiter sich in Lichtauskopplungsrichtung aufteilen, um so das Licht für die zweite Lichtfunktion an mehreren Orten auszukoppeln. Vorteilhafterweise kann dadurch das Licht für die zweite Lichtfunktion flexibel an mehreren Orten bereitgestellt werden.According to a further embodiment of the headlamp system, the light guide can be split in light extraction direction, so as to couple out the light for the second light function at a plurality of locations. Advantageously, the light for the second light function can thereby be provided flexibly at several locations.

Die erste Lichtfunktion des Scheinwerfersystems kann ein Abblendlicht und/oder ein Fernlicht sein, die zweite Lichtfunktion ein Tagfahrlicht und/oder ein Positionslicht. Vorteilhafterweise können somit mehrere Lichtfunktionen flexibel bereitgestellt werden. Das Abblendlicht kann insbesondere abwechselnd mit dem Tagfahrlicht benutzt werden, wobei das Positionslicht auch zusätzlich z. B. zum Abblendlicht verwendet werden kann.The first light function of the headlight system may be a dipped beam and / or a high beam, the second light function a daytime running light and / or a position light. Advantageously, multiple light functions can thus be provided flexibly. The dipped beam can be used in particular alternately with the daytime running lights, the position light also in addition z. B. can be used for dipped beam.

Ein weiterer Vorteil des erfindungsgemäßen Scheinwerfersystems ist, dass alle Lichtfunktionen die gleiche Lichtfarbe besitzen, da nur eine einzige bzw. eine gemeinsame Lichtquelle für die verschiedenen Lichtfunktionen verwendet wird.Another advantage of the headlamp system according to the invention is that all light functions have the same light color, since only a single or a common light source is used for the different light functions.

Die Erfindung wird nun anhand von Ausführungsbeispielen mit Bezug zu den Zeichnungen erläutert.

Die unterschiedlichen Ausführungsbeispiele des Scheinwerfersystems, das eine Lichtquelle, eine erste Einrichtung für eine Lichtfunktion und eine zweite Einrichtung für eine andere Lichtfunktion aufweist, werden nun detaillierter beschrieben. Die Fig. 1 bis 4 zeigen Scheinwerfersysteme 101, 201, 301, 401, die sich in der Art der Lichtauskopplung für eine zweite Lichtfunktion unterscheiden und ansonsten in Bezug auf die erste Lichtfunktion ähnlich sind. Zunächst werden die Gemeinsamkeiten der Scheinwerfersysteme 101, 201, 301, 401 erläutert. Anschließend werden die unterschiedlichen Ausführungsbeispiele betrachtet, um deren Besonderheiten bzgl. der Lichtauskopplung 118, 218, 318, 418, 119, 219, 319, 419, 220 für die zweite Lichtfunktion näher zu erläutern.The different embodiments of the headlamp system, which has a light source, a first device for a light function and a second device for a different light function, will now be described in more detail. The Fig. 1 to 4 show headlight systems 101, 201, 301, 401, which differ in the type of light extraction for a second light function and are otherwise similar with respect to the first light function. First, the similarities of the headlamp systems 101, 201, 301, 401 will be explained. Subsequently, the different embodiments are considered in order to explain their particularities with respect to the light extraction 118, 218, 318, 418, 119, 219, 319, 419, 220 for the second light function in more detail.

Eine Lichtquelle 102, 202, 302, 402 emittiert Licht direkt bzw. mittels eines Hauptreflektors 104, 204, 304, 404 in Lichtemissionsrichtung 103, 203, 303, 403 durch eine Öffnung 109, 209, 309, 409 für eine erste Lichtfunktion in seine Umgebung. Eine zweite Einrichtung kann die Öffnung 109, 209, 309, 409 für die erste Lichtfunktion optisch verschließen. Beispielsweise ist die zweite Einrichtung eine Blende 108, 208, 308, 408. Die erste Lichtfunktion wird dann bereitgestellt, wenn die Blende 108, 208, 308, 408 die Öffnung für die erste Lichtfunktion optisch nicht verschließt. Die erste Lichtfunktion kann jedoch nicht mehr bereitgestellt werden, wenn die Blende 108, 208, 308, 408 die Öffnung für die erste Lichtfunktion optisch verschließt. Bei allen beschriebenen Ausführungsbeispielen werden die Blenden 108, 208, 308, 408 jeweils um die Achsen 110, 111, 210, 211, 310, 311, 410, 411 zum Öffnen und Schließen geschwenkt.A light source 102, 202, 302, 402 emits light directly or by means of a main reflector 104, 204, 304, 404 in the light emission direction 103, 203, 303, 403 through an opening 109, 209, 309, 409 for a first light function in its surroundings , A second device may optically close the opening 109, 209, 309, 409 for the first light function. For example, the second device is a shutter 108, 208, 308, 408. The first light function is provided when the shutter 108, 208, 308, 408 does not optically close the opening for the first light function. However, the first light function can no longer be provided if the aperture 108, 208, 308, 408 optically closes the opening for the first light function. In all of the described embodiments, the apertures 108, 208, 308, 408 are respectively pivoted about the axes 110, 111, 210, 211, 310, 311, 410, 411 for opening and closing.

Des Weiteren ist eine ersten Einrichtung vorgesehen, mittels welcher zumindest ein Teil des von der Lichtquelle 102, 202, 302, 402 emittierten Lichts zur Bereitstellung einer zweiten Lichtfunktion umlenkbar und auskoppelbar ist. Das von der Lichtquelle 102, 202, 302, 402 emittierte und auf die zweite Einrichtung 108, 208, 308, 408 auftreffende Licht kann erfindungsgemäß jedoch nicht zur Bereitstellung der zweiten Lichtfunktion ausgekoppelt werden. Beispielsweise ist die zweite Einrichtung 108, 208, 308, 408 so ausgebildet, dass das auf sie auftreffende Licht absorbiert wird. Ferner könnte das auf die zweite Einrichtung 108, 208, 308, 408 auftreffende Licht in eine Richtung reflektiert werden, in der eine Auskopplung für die zweite Lichtfunktion nicht möglich ist.Furthermore, a first device is provided by means of which at least part of the light emitted by the light source 102, 202, 302, 402 can be deflected and coupled out to provide a second light function. However, according to the invention, the light emitted by the light source 102, 202, 302, 402 and incident on the second device 108, 208, 308, 408 can not be coupled out to provide the second light function. For example, the second device 108, 208, 308, 408 is designed so that the light incident on it is absorbed. Furthermore, the light incident on the second device 108, 208, 308, 408 could be reflected in a direction in which a coupling-out for the second light function is not possible.

Im folgenden werden verschiedene Ausführungen der ersten Einrichtung beschrieben:

  • Die Fig. 1 zeigt ein erstes Ausführungsbeispiel eines Scheinwerfersystems 101 mit einem unverzweigten Lichtleiter 112. Der Lichtleiter 112 weist einen Bereich zur Lichteinkopplung 105 auf, durch welchen Licht aus dem Innenraum des Scheinwerfers 121 für eine zweite Lichtfunktion ausgekoppelt werden kann. Der Lichtleiter 112 ist dabei so im Innenraum 121 angeordnet, dass genügend Licht für die zweite Lichtfunktion in den Lichtleiter 112 eingekoppelt wird, der Lichtleiter den Strahlengang für die erste Lichtfunktion jedoch nicht beeinflusst. Das ausgekoppelte Licht aus dem Innenraum 121 wird anfänglich in Richtung des Pfeils 118 durch den Lichtleiter geleitet und dann als zweite Lichtfunktion in Richtung des Pfeils 119 bereitgestellt. Falls die zweite Lichtfunktion bei eingeschalteter Lichtquelle 102 nicht fortwährend betrieben wird, kann vor der Lichtauskoppelfläche optional eine (nicht gezeigte) Blende vorgesehen sein, die geöffnet und verschlossen werden kann.
In the following, various embodiments of the first device will be described:
  • The Fig. 1 shows a first embodiment of a headlamp system 101 with an unbranched light guide 112. The light guide 112 has an area for light coupling 105, through which light from the interior of the headlamp 121 can be coupled for a second light function. The light guide 112 is arranged in the interior 121 such that sufficient light for the second light function is coupled into the light guide 112, but the light guide does not influence the beam path for the first light function. The outcoupled light from the interior 121 is initially directed in the direction of the arrow 118 through the light guide and then provided as a second light function in the direction of the arrow 119. If the second light function is not continuously operated when the light source 102 is switched on, an aperture (not shown) may optionally be provided in front of the light output surface, which aperture can be opened and closed.

Die Fig. 2 zeigt ein zweites Ausführungsbeispiel eines Scheinwerfersystems 201 mit zwei hintereinander angeordneten Lichtleitern 212, 216. Der Lichtleiter 212 weist wie der Lichtleiter 112 des ersten Ausführungsbeispiels einen Bereich zur Lichteinkopplung 205 auf, durch welchen Licht aus dem Innenraum des Scheinwerfers 221 für die zweite Lichtfunktion ausgekoppelt werden kann. Dieses ausgekoppelte Licht aus dem Innenraum des Scheinwerfers 221 wird in Richtung des Pfeils 218 durch den Lichtleiter geleitet. Der erste Lichtleiter 212 ist durch den Lichtleiterkoppler 215 mit dem zweiten Lichtleiter 216 verbunden. Der Lichtleiter 216 besteht selbst aus einer Vielzahl von Lichtleiteradern. Diese einzelnen Lichtleiteradern können an den dargestellten Orten 217 in unterschiedlichen Richtungen weiterverlaufen und sich selbst an den dargestellten Orten 217 auch noch verzweigen. Das ursprünglich in Richtung des Pfeils 218 ausgekoppelte Licht kann somit bei verschiedenen Orten ausgekoppelt werden, um die zweite Lichtfunktion bereitzustellen.The Fig. 2 shows a second embodiment of a headlamp system 201 having two light guides 212, 216 arranged one behind the other. The light guide 212 has, like the light guide 112 of the first embodiment, an area for light coupling 205, through which light from the interior of the headlight 221 for the second light function can be coupled , This decoupled light from the interior of the headlight 221 is passed in the direction of arrow 218 through the light guide. The first optical fiber 212 is connected to the second optical fiber 216 through the optical fiber coupler 215. The light guide 216 itself consists of a plurality of optical fiber wires. These individual optical fiber cores can continue to run in different directions at the locations 217 shown and even branch off at the locations 217 shown. The light originally decoupled in the direction of the arrow 218 can thus coupled out at different locations to provide the second light function.

Die Fig. 3 zeigt ein drittes Ausführungsbeispiel eines Scheinwerfersystems 301, wobei die Lichtauskopplung für die zweite Lichtfunktion über Reflektoren 313, 314 erfolgt. Der Reflektor 313 für die Lichtauskopplung der Lichtemission der Lichtquelle 302 für die zweite Lichtfunktion ist schwenkbar oder verschiebbar, wobei in einer ersten Position von der Lichtquelle 302 emittiertes Licht von dem Reflektor 313 reflektiert wird und der Reflektor 313 sich in einer zweiten Position nicht im Strahlengang des von der Lichtquelle 302 emittierten Lichts befindet. Falls der Reflektor 313 somit die in Fig. 3 gezeigte erste Position einnimmt, wird Licht aus dem Scheinwerferinnenraum 321 über die Reflektorfläche 306 des ersten Reflektors 313 ausgekoppelt und zur Reflektorfläche 307 eines zweiten Reflektors 314 geleitet. Von dort wird das Licht in Richtung des Pfeils 319 reflektiert und kann auf diese Weise die zweite Lichtfunktion bereitstellen. Falls erforderlich, können noch weitere nicht dargestellte Reflektoren verwendet werden.The Fig. 3 shows a third embodiment of a headlight system 301, wherein the light extraction for the second light function via reflectors 313, 314 takes place. The reflector 313 for the light extraction of the light emission of the light source 302 for the second light function is pivotable or displaceable, wherein in a first position of the light source 302 emitted light from the reflector 313 is reflected and the reflector 313 in a second position not in the beam path of the is located from the light source 302 emitted light. If the reflector 313 thus the in Fig. 3 shown first position, light is coupled out of the headlight interior 321 via the reflector surface 306 of the first reflector 313 and directed to the reflector surface 307 of a second reflector 314. From there, the light is reflected in the direction of the arrow 319 and can thus provide the second light function. If necessary, other reflectors, not shown, can be used.

Die Fig. 4 zeigt ein viertes Ausführungsbeispiel eines Scheinwerfersystems 401, wobei die Lichtauskopplung für die zweite Lichtfunktion über eine weitere mögliche Anordnung der Reflektoren 413, 414 erfolgt. Die Beschreibung der Fig. 4 entspricht somit derjenigen der Fig. 3 mit den entsprechend geänderten Bezugszeichen. Der Reflektor 413 für die Lichtauskopplung der Lichtemission der Lichtquelle 402 für die zweite Lichtfunktion ist schwenkbar oder verschiebbar, wobei in einer ersten Position von der Lichtquelle 402 emittiertes Licht von dem Reflektor 413 reflektiert wird und der Reflektor 413 sich in einer zweiten Position nicht im Strahlengang des von der Lichtquelle 402 emittierten Lichts befindet. Falls der Reflektor 413 somit die erste Position einnimmt, wird Licht aus dem Scheinwerferinnenraum 421 über die Reflektorfläche 406 des ersten Reflektors 413 ausgekoppelt und zur Reflektorfläche 407 des zweiten Reflektors 414 geleitet. Von dort wird das Licht in Richtung des Pfeils 419 reflektiert und kann die zweite Lichtfunktion bereitstellen. Falls erforderlich, können auch bei diesem Ausführungsbeispiel weitere nicht dargestellte Reflektoren verwendet werden.The Fig. 4 shows a fourth embodiment of a headlight system 401, wherein the light extraction for the second light function via a further possible arrangement of the reflectors 413, 414 takes place. The description of Fig. 4 thus corresponds to that of Fig. 3 with the correspondingly changed reference numerals. The light emission reflector 413 of the light source 402 for the second light function is pivotable or displaceable, wherein light emitted by the light source 402 is reflected by the reflector 413 in a first position and the reflector 413 is not in the beam path of the second is located from the light source 402 emitted light. If the reflector 413 thus assumes the first position, light is coupled out of the headlight interior 421 via the reflector surface 406 of the first reflector 413 and directed to the reflector surface 407 of the second reflector 414. From there, the light is reflected in the direction of the arrow 419 and can provide the second light function. If necessary, other reflectors, not shown, can also be used in this embodiment.

In den Figuren werden die Blenden 108, 208, 308, 408 schwenkbar um ihre jeweiligen Schwenkachsen 110, 210, 310, 410, 111, 211, 311, 411 zum Öffnen und Verschließen der Öffnung gezeigt. Die Blenden müssen jedoch nicht zwingend drehbar oder verschwenkbar sein, sondern können auch verschiebbar sein, um die gleiche Funktion bereitzustellen.In the figures, the panels 108, 208, 308, 408 are pivotally mounted about their respective pivot axes 110, 210, 310, 410, 111, 211, 311, 411 for opening and closing the opening. However, the bezels need not necessarily be rotatable or pivotable, but may be slidable to provide the same function.

In den Figuren 3 und 4 werden die Reflektoren 313, 413 drehbar zum Ein- und Ausstellen gezeigt. Die Reflektoren 313, 413 müssen jedoch nicht zwingend drehbar oder verschwenkbar sein, sondern können auch verschiebbar sein, um die gleiche Funktion bereitzustellen.In the Figures 3 and 4 the reflectors 313, 413 are rotatably shown for switching on and off. However, the reflectors 313, 413 need not necessarily be rotatable or pivotable, but may be slidable to provide the same function.

Mit den verschiedenen vorstehend beschriebenen Ausführungsbeispielen des Scheinwerfersystems 101, 201, 301, 401 kann als erste Lichtfunktion ein Abblendlicht oder Fernlicht bereitgestellt werden. Die zweite Lichtfunktion kann z. B. ein Tagfahrlicht oder Positionslicht sein. Die Verwendung von nur einer Lichtquelle 102, 202, 302, 402 bewirkt im Betrieb, dass die erste und die zweite Lichtfunktion immer die gleiche Lichtfarbe haben.With the various exemplary embodiments of the headlight system 101, 201, 301, 401 described above, a dipped beam or high beam can be provided as the first light function. The second light function can, for. B. be a daytime running light or position light. The use of only one light source 102, 202, 302, 402 causes in operation that the first and the second light function always have the same light color.

Es kann vorgesehen sein, dass das Abblend- und das Tagfahrlicht nicht zur selben Zeit betrieben werden können. Gleiches kann für die Kombination von Fern- und Tagfahrlicht vorgesehen sein, weswegen hier nur die Kombination von Abblend- und Tagfahrlicht näher erläutert wird.It can be provided that the low beam and the daytime running lights can not be operated at the same time. The same can be provided for the combination of long-distance and daytime running lights, which is why only the combination of low beam and daytime running lights is explained in more detail here.

Um das Abblendlicht ein- und das Tagfahrlicht auszuschalten, wird die Blende 108, 208, 308, 408 geöffnet, so dass Licht für die erste Lichtfunktion, d. h. das Abblendlicht, durch die Öffnung 109, 209, 309, 409 durchtreten kann. Ferner wird durch die erste Einrichtung 112, 212, 313, 413 kein Licht für die zweite Lichtfunktion, dem Tagfahrlicht, ausgekoppelt. Um das Abblendlicht aus- und das Tagfahrlicht einzuschalten, wird die Blende 108, 208, 308, 408 geschlossen, so dass keine Licht mehr für die erste Lichtfunktion, d. h. das Abblendlicht, durch die Öffnung 109, 209, 309, 409 durchtreten kann. Gleichzeitig wird jedoch Licht mittels der ersten Einrichtung 112, 212, 313, 413 für die zweite Lichtfunktion, dem Tagfahrlicht, ausgekoppelt.To switch the low beam on and off the daytime running light, the aperture 108, 208, 308, 408 is opened, so that light for the first light function, d. H. the low beam through which opening 109, 209, 309, 409 can pass. Furthermore, no light for the second light function, the daytime running light, is coupled out by the first device 112, 212, 313, 413. To turn off the low beam and turn on the daytime running light, the aperture 108, 208, 308, 408 is closed, so that no more light for the first light function, d. H. the low beam through which opening 109, 209, 309, 409 can pass. At the same time, however, light is coupled out by means of the first device 112, 212, 313, 413 for the second light function, the daytime running light.

Für das Abblend- und das Positionslicht kann vorgesehen sein, dass sie gleichzeitig betrieben werden können. Um das Abblendlicht und das Positionslicht gleichzeitig einzuschalten, wird die Blende 108, 208, 308, 408 geöffnet. Gleichzeitig wird von der ersten Einrichtung 112, 212, 313, 413 Licht für die zweite Lichtfunktion, dem Positionslicht, ausgekoppelt.For the low beam and the position light can be provided that they can be operated simultaneously. To simultaneously turn on the low beam and the position light, the aperture 108, 208, 308, 408 is opened. At the same time, the first device 112, 212, 313, 413 decouples light for the second light function, the position light.
