Description

Die Erfindung betrifft eine Kraftfahrzeuginnenbeleuchtung.The invention relates to a motor vehicle interior lighting.

Neuere Kraftfahrzeuge verfügen im Innenraum zunehmend über sogenannte ambiente Lichtfunktionen, die je nach Fahrzeugtyp oder Zielgruppe für eine dezente oder auffallende Ausleuchtung des Innenraumes sorgen. Der Einsatz dieser Art der Beleuchtung erleichtert den Passagieren im Fahrzeug die Orientierung und schafft eine individuelle und wohnliche Atmosphäre.In the interior, newer motor vehicles increasingly have so-called ambient light functions, which, depending on the vehicle type or target group, provide discreet or striking illumination of the interior. The use of this type of lighting makes it easier for passengers in the vehicle to orient themselves and creates an individual and homely atmosphere.

Aus der DE 10 2009 039 556 A1 ist ein Beleuchtungssystem, insbesondere für den Innenraum eines Fahrzeugs, bekannt, umfassend zumindest einen seitlich emittierenden Lichtleiter, welcher ein Faserbündel seitenemittierender Fasern umfasst, wobei das Faserbündel in einer rundum umschlossenen transparenten Kunststoffummantelung angeordnet ist, in welcher die seitenemittierenden Fasern zumindest in axialer Richtung gegeneinander beweglich sind.From the DE 10 2009 039 556 A1 is an illumination system, in particular for the interior of a vehicle, known comprising at least one laterally emitting light guide, which comprises a fiber bundle of side emitting fibers, wherein the fiber bundle is disposed in a completely enclosed transparent plastic sheath in which the side emitting fibers at least in the axial direction against each other are.

Insbesondere werden dabei Stufen-Index-Fasern verwendet. Das Faserbündel seitenemittierender Fasern ist dabei in einer rundum umschlossenen Kunststoffummantelung angeordnet. Unter rundum umschlossen wird dabei verstanden, dass in Querschnittsbetrachtung die Kunststoffummantelung um das gesamte Faserbündel herum geschlossen ist, also insbesondere nicht etwa seitlich aufgeschnitten wurde, um die Fasern einzulegen. Außerdem sind dabei die seitenemittierender Fasern zumindest in axialer Richtung gegeneinander beweglich. Eine Beweglichkeit der Fasern zueinander wird insbesondere dadurch erreicht, dass die Kunststoffummantelung im Bereich des Faserbündels ausgespart ist, also insbesondere eine Art Schlauch bildet, in welchem die Fasern eingebettet sind. Dadurch wird erreicht, dass enge Biegeradien möglich sind, ohne dass die seitenemittierenden Fasern brechen.In particular, step index fibers are used. The fiber bundle of side-emitting fibers is arranged in a completely enclosed plastic sheath. In this context, it is understood that the plastic covering is closed around the entire fiber bundle in a cross-sectional view, ie, in particular, it has not been cut laterally in order to lay in the fibers. In addition, the side-emitting fibers are movable relative to each other at least in the axial direction. A mobility of the fibers to each other is achieved in particular by the fact that the plastic coating is recessed in the region of the fiber bundle, so in particular forms a kind of hose in which the fibers are embedded. This ensures that tight bending radii are possible without the side-emitting fibers breaking.

Eine Einkopplung von Licht oder eine Ansteuerung von Lichtquellen, mit welchen dieses Beleuchtungssystem besonders vorteilhaft eingesetzt werden kann ist in der DE 10 2009 039 556 A1 nicht offenbart.A coupling of light or a control of light sources, with which this illumination system can be used particularly advantageously in the DE 10 2009 039 556 A1 not revealed.

Der Erfindung liegt die Aufgabe zu Grunde, eine auffallende und variable Kraftfahrzeuginnenbeleuchtung anzugeben.The invention is based on the object to provide a striking and variable automotive interior lighting.

Diese Aufgabe wird gelöst durch die Merkmale des unabhängigen Patentanspruchs. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.This object is solved by the features of the independent claim. Advantageous developments of the invention will become apparent from the dependent claims.

Eine erfindungsgemäße Kraftfahrzeuginnenbeleuchtung umfasst eine Vielzahl von seitlich emittierenden Lichtleitern, die jeweils mindestens ein Faserbündel seitenemittierender Fasern, insbesondere Glasfasern, umfassen, wobei die Lichtleiter miteinander verdrillt oder verflochten sind.A motor vehicle interior lighting according to the invention comprises a plurality of laterally emitting optical fibers, each comprising at least one fiber bundle of side emitting fibers, in particular glass fibers, wherein the optical fibers are twisted or intertwined with each other.

Je nach Ausführungsvariante kann die Kraftfahrzeuginnenbeleuchtung auch eine oder mehrere Lichtquellen umfassen, um Licht in die Lichtleiter einzukoppeln. Auch eine Steuereinrichtung zum Ansteuern der Lichtquellen kann Bestandteil der Kraftfahrzeuginnenbeleuchtung sein.Depending on the embodiment variant, the motor vehicle interior lighting can also include one or more light sources in order to couple light into the light guides. A control device for controlling the light sources may also be part of the motor vehicle interior lighting.

Dadurch wird mit geringem Aufwand eine vielseitig einsetzbare und funktional flexible Kraftfahrzeuginnenbeleuchtung geschaffen, die aufgrund ihrer mechanischen Flexibilität hervorragend in verschiedene Kraftfahrzeugtypen integrierbar ist.As a result, a versatile and functional flexible automotive interior lighting is created with little effort, which is perfectly integrated into different types of vehicles due to their mechanical flexibility.

Vorzugsweise sind die Faserbündel jeweils in einer rundum umschlossenen transparenten Kunststoffummantelung angeordnet, in welcher die seitenemittierenden Fasern zumindest in axialer Richtung gegeneinander beweglich sind.Preferably, the fiber bundles are each arranged in a completely enclosed transparent plastic casing, in which the side-emitting fibers are movable relative to each other at least in the axial direction.

Dadurch wird die mechanische Flexibilität und Stabilität der Lichtleiter und damit der Kraftfahrzeuginnenbeleuchtung erhöht.As a result, the mechanical flexibility and stability of the light guide and thus the motor vehicle interior lighting is increased.

Es ist eine Weiterbildung der Erfindung, dass den Lichtleitern jeweils eine Lichtquelle, insbesondere eine LED oder RGB-LED, zugeordnet ist, die derart relativ zu dem Lichtleiter angeordnet ist, dass Licht der Lichtquelle in den Lichtleiter einkoppelbar ist.It is a further development of the invention that the light guides each have a light source, in particular an LED or RGB LED, assigned, which is arranged relative to the light guide such that light of the light source can be coupled into the light guide.

Dadurch kann in die verschiedenen Lichtleiter beispielsweise verschiedenfarbiges Licht oder Licht zu verschiedenen Zeiten eingekoppelt werden. Dadurch können auffallende Lichteffekte generiert werden.As a result, differently colored light or light can be coupled in at different times into the different light guides, for example. As a result, striking light effects can be generated.

Bei einer anderen Weiterbildung ist eine Steuereinrichtung zur Steuerung der Lichtquellen vorgesehen, die hardwaretechnisch und/oder programmtechnisch derart eingerichtet und mit den Lichtquellen gekoppelt ist, dass Licht der verschiedenen Lichtquellen nacheinander jeweils in die verschiedenen, den Lichtquellen jeweils zugeordneten Lichtleiter eingekoppelt wird. Insbesondere eine zeitlich sequentielle und zyklische Aktivierung der Lichtquellen kann dabei besonders vorteilhaft sein.In another development, a control device for controlling the light sources is provided, which is hardware-technically and / or program-technically so coupled and coupled to the light sources, that light of the different light sources successively each coupled into the different, the light sources associated light guide. In particular, a temporally sequential and cyclical activation of the light sources can be particularly advantageous.

Vorzugsweise wird dabei zunächst eine erste Lichtquelle aktiviert, um Licht in einen ersten Lichtleiter einzukoppeln. Mit (gleichzeitig, kurz davor oder kurz danach) der Deaktivierung dieser ersten Lichtquelle wird eine zweite Lichtquelle aktiviert, um Licht in einen zweiten Lichtleiter einzukoppeln, usw. Mit der Deaktivierung einer letzten Lichtquelle wird dann wieder die erste Lichtquelle aktiviert, um Licht in den ersten Lichtleiter einzukoppeln.Preferably, a first light source is first activated in order to couple light into a first light guide. With (simultaneously, shortly before or shortly after) the deactivation of this first light source, a second light source is activated to couple light into a second light guide, etc. With the deactivation of a last light source is then again activates the first light source to couple light into the first light guide.

In Kombination mit den verdrillten oder verflochtenen Lichtleitern kann so ein ”laufendes Licht” erzeugt werden, durch dessen ”Laufrichtung” beispielsweise situationsabhängig auf Bedienelemente eines Kraftfahrzeuges hingewiesen werden kann oder ein Energiefluss visualisiert werden kann.In combination with the twisted or intertwined optical fibers so "running light" can be generated, can be pointed by the "direction", for example, depending on the situation on controls a motor vehicle or energy flow can be visualized.

Je nach Ausführungsvarianten kann der Übergang von einer Lichtquelle auf die nächste Lichtquelle dabei auch ”fließend” erfolgen. Beispielsweise wird die Lichtstärke einer aktiven Lichtquelle kontinuierlich auf null reduziert, und gleichzeitig, danach oder zeitliche überlappend die Lichtstärke einer weiteren Lichtquelle kontinuierlich erhöht bis diese als aktive Lichtquelle ihre volle Lichtstärke abstrahlt. Dann oder nach einer vorgegebenen Zeitspanne wird die Lichtstärke dieser aktiven Lichtquelle kontinuierlich auf null reduziert, und gleichzeitig die Lichtstärke einer weiteren Lichtquelle kontinuierlich erhöht bis diese als aktive Lichtquelle ihre volle Lichtstärke abstrahlt, usw.Depending on the design variants, the transition from one light source to the next light source can also take place "fluently". For example, the luminous intensity of an active light source is continuously reduced to zero, and at the same time, thereafter or overlapping in time, the luminous intensity of another light source is continuously increased until it emits its full intensity as an active light source. Then or after a predetermined period of time, the light intensity of this active light source is continuously reduced to zero, and at the same time continuously increases the light intensity of another light source until it emits its full intensity as an active light source, etc.

Vorzugsweise ist durch die Lichtquellen jeweils Licht verschiedener Farben in die die verschiedenen oder jeweils einen Lichtleiter einkoppelbar. Dazu können die Lichtquellen beispielsweise RGB-Leuchtdioden umfassen.Preferably, by the light sources each light of different colors in which the different or each one optical fiber can be coupled. For this purpose, the light sources may comprise, for example, RGB light-emitting diodes.

Dadurch können noch auffälligere Lichteffekte erzeugt werden.As a result, even more striking lighting effects can be generated.

Im Rahmen der Erfindung liegt auch ein Kraftfahrzeug mit einem Bedienelement und einer oben beschriebenen Kraftfahrzeuginnenbeleuchtung, wobei das Steuergerät derart eingerichtet ist, dass die ”Laufrichtung” des laufenden Lichtes auf den Ort des Bedienelementes hinweist.In the context of the invention is also a motor vehicle with an operating element and a motor vehicle interior lighting described above, wherein the control device is set up such that the "running direction" of the current light points to the location of the operating element.

Im Folgenden wird die Erfindung anhand von Beispielen unter Bezugnahme auf die folgende Figur näher erläutert:In the following the invention will be explained in more detail by means of examples with reference to the following figure:

1 zeigt eine Kraftfahrzeuginnenbeleuchtung mit einer Vielzahl von Lichtleitern LL1, LL2, LL3, die miteinander verdrillt sind. Die flexiblen Lichtleiter LL1, LL2, LL3 umfassen jeweils ein flexibles Faserbündel seitenemittierender Fasern. Die Faserbündel sind jeweils in einer rundum umschlossenen transparenten Kunststoffummantelung angeordnet, in welcher die seitenemittierenden Fasern zumindest in axialer Richtung gegeneinander beweglich sind. Beispielsweise können die Faserbündel gemäß der Offenbarung in der DE 10 2009 039 556 A1 gebildet sein. 1 shows a motor vehicle interior lighting with a plurality of optical fibers LL1, LL2, LL3, which are twisted together. The flexible light guides LL1, LL2, LL3 each include a flexible fiber bundle of side emitting fibers. The fiber bundles are each arranged in a completely enclosed transparent plastic casing, in which the side-emitting fibers are movable relative to one another at least in the axial direction. For example, the fiber bundles according to the disclosure in US Pat DE 10 2009 039 556 A1 be formed.

Den Lichtleitern LL1, LL2, LL3 ist als Lichtquelle jeweils eine Leuchtdiode LED1, LED2, LED3 zugeordnet. Die Leuchtdioden LED1, LED2, LED3 sind derart angeordnet, dass das durch die Leuchtdioden abgestrahlte Licht Im Wesentlichen jeweils in den zugehörigen Lichtleiter LL1, LL2, LL3, insbesondere in dessen Stirnseite, eingekoppelt wird.The light guides LL1, LL2, LL3 is assigned as a light source in each case a light-emitting diode LED1, LED2, LED3. The light-emitting diodes LED1, LED2, LED3 are arranged such that the light emitted by the light-emitting diodes is in each case essentially coupled into the associated light guide LL1, LL2, LL3, in particular in its end face.

Die Leuchtdioden LED1, LED2, LED3 werden durch ein Steuergerät STE1 in an sich bekannter Weise angesteuert.The LEDs LED1, LED2, LED3 are controlled by a control unit STE1 in a conventional manner.

Gemäß einer bevorzugten Ausgestaltung erfolgt die Ansteuerung der Leuchtdioden LED1, LED2, LED3 derart, dass die Leuchtdioden LED1, LED2, LED3 zeitlich sequentiell und zyklisch aktiviert werden. Beispielsweise wird zuerst die Leuchtdiode LED3 aktiviert. Dann wird diese deaktiviert und im Zuge der Deaktivierung die Leuchtdiode LED2 aktiviert. Dann wird diese deaktiviert und im Zuge der Deaktivierung die Leuchtdiode LED1 aktiviert. Dann wird diese deaktiviert und im Zuge der Deaktivierung wieder die Leuchtdiode LED3 aktiviert, usw.. Die Aktivierung bzw. Deaktivierung der Leuchtdioden LED1, LED2, LED3 kann dabei kontinuierlich oder diskret erfolgen. Dadurch wird ein ”laufendes Licht” erzeugt, das in einem Kraftfahrzeug für verschiedene wecke eingesetzt werden kann.According to a preferred embodiment, the activation of the light-emitting diodes LED1, LED2, LED3 takes place in such a way that the light-emitting diodes LED1, LED2, LED3 are activated sequentially and cyclically in time. For example, first the LED LED3 is activated. Then this is deactivated and activated in the course of deactivation, the LED LED2.
