Durch US 2004/0136200 A1 ist ein Scheinwerfer für ein Kraftfahrzeug bekannt, mit in den Strahlengang zwischen einem Leuchtmittel und einer Lichtscheibe einschwenkbaren Elementen. Die Elemente können beispielsweise als Filter ausgeführt sein.By US 2004/0136200 A1 is a headlight for a motor vehicle is known, with in the beam path between a light source and a lens einschwenkbaren elements. The elements can be designed, for example, as a filter.

Durch DE 434356 ist eine Leuchte für Kraftfahrzeuge bekannt, mit einem Leuchtengehäuse, in dem wenigstens ein Leuchtmittel untergebracht ist, dessen Licht zur Erzeugung einer Signal/Leuchtenfunktion durch wenigstens eine Lichtscheibe nach außen tritt. Das Leuchtmittel ist in wenigstens zwei Lagen verstellbar, in denen das Licht durch unterschiedliche Signal/Leuchtfunktionen erzeugende Lichtscheibenbereiche strahlt. Das einen Reflektor bildende Leuchtengehäuse stellt hierbei ein im Strahlweg zwischen dem Leuchtmittel und der Lichtscheibe angeordnetes ortsfestes Element dar, das wenigstens zwei Bereiche aufweist, denen unterschiedliche Signal/Leuchtenfunktionen zugeordnet sind, wobei das Leuchtmittel so verstellbar ist, dass das von ihm ausgehende Licht je nach Signal/Leuchtenfunktion dem entsprechenden Bereich zugeführt wird.By DE 434356 a luminaire for motor vehicles is known, with a luminaire housing, in which at least one light source is accommodated, the light of which is emitted to generate a signal / luminaire function by at least one lens to the outside. The luminous means is adjustable in at least two layers in which the light radiates through different signal / luminous functions producing light disc areas. The luminaire housing forming a reflector in this case represents a stationary element arranged in the beam path between the luminous means and the lens, which has at least two areas to which different signal / luminaire functions are assigned, wherein the luminous means is adjustable so that the light emanating from it depends on the light emitted by it Signal / luminaire function is supplied to the corresponding area.

Durch DE 102 18 661 A1 ist eine Signalleuchte für Kraftfahrzeuge bekannt, mit einer im Strahlengang zwischen Lichtscheibe und Leuchtmittel angeordneten, lichtstreuenden Zusatzscheibe. Anstelle der Zusatzscheibe können im Reflektor Licht ablenkende Optikelemente angeordnet sein.By DE 102 18 661 A1 a signal light for motor vehicles is known, with a arranged in the beam path between the lens and light source, light scattering additional disc. Instead of the additional disk light-deflecting optical elements can be arranged in the reflector.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Leuchte so auszubilden, dass die Signal- und/oder Leuchtenfunktionen in konstruktiv einfacher Weise erreicht werden können.The invention has the object of providing the generic lamp in such a way that the signal and / or lighting functions can be achieved in a structurally simple manner.

Diese Aufgabe wird gelöst mit den Merkmalen des Anspruchs 1 bzw. 4.This object is achieved with the features of claim 1 or 4.

Bei der erfindungsgemäßen Leuchte ist in den Strahlweg zwischen dem Leuchtmittel und der Lichtscheibe das Element verstellbar, durch das eine andere Signal- bzw. Leuchtenfunktion der Leuchte erreicht wird.In the luminaire according to the invention, the element is adjustable in the beam path between the light source and the lens, by which a different signal or luminaire function of the lamp is achieved.

Gemäß einer ersten Ausgestaltung der Erfindung ist das Element eine Folie, die bei Bedarf zwischen das Leuchtmittel und die Lichtscheibe verstellt wird. Die Folie ist vorteilhaft auf eine vorzugsweise außerhalb des Leuchtengehäuses angeordnete Trommel aufwickelbar. Eine Folie hat nur ein geringes Gewicht und kann darum sehr schnell zwischen der Gebrauchs- und der Außergebrauchsstellung verstellt werden.According to a first embodiment of the invention, the element is a film which is adjusted as needed between the lamp and the lens. The film is advantageously wound on a preferably arranged outside the lamp housing drum. A film has only a low weight and can therefore be adjusted very quickly between the used and the non-use position.

Gemäß einer zweiten Ausgestaltung der Erfindung ist das Element eine Lamelle, die aus einer in Strahlrichtung des Leuchtmittels liegenden Auβergebrauchsstellung in eine quer zur Strahlrichtung liegende Gebrauchsstellung verstellbar ist. Vorteilhaft sind mehrere Lamellen vorgesehen, die gemeinsam verstellbar sind.According to a second embodiment of the invention, the element is a lamella, which can be adjusted from a lying in the beam direction of the illuminant Auεzubrauchsstellung in a direction transverse to the beam direction of use position. Advantageously, a plurality of slats are provided, which are adjustable together.

So kann beispielsweise bei einer Heckleuchte zum Beispiel für das Nebelschlusslicht und das Rückfahrlicht eine einzige Leuchten- bzw. Reflektorkammer verwendet werden. Je nach Stellung dieses Elementes wird dann die Funktion des Nebelschlusslichtes oder des Rückfahrlichtes erzeugt. Da für beide Signal- bzw. Leuchtenfunktionen nur eine einzige Leuchtmittelkammer bzw. Reflektorkammer erforderlich ist, weist die erfindungsgemäße Leuchte nur einen geringen Bauraum auf. Die Designmöglichkeiten der Leuchte können dadurch erheblich erweitert werden. Um beispielsweise den Farbort für die Nebelschlusslichtfunktion zu treffen, wird das Element als Farbfilter ausgebildet und dem Leuchtmittel vorgeschaltet. Ist das Element nicht vorgeschaltet, dann ergibt sich die Rückfahrlichtfunktion. Mit der erfindungsgemäßen Leuchte können selbstverständlich auch andere Signal- und/oder Leuchtenfunktionen erzielt werden.For example, in a rear light, for example, for the rear fog light and the reversing light, a single luminaire or reflector chamber can be used. Depending on the position of this element, the function of the rear fog light or the reversing light is then generated. There only a single illuminant chamber or reflector chamber is required for both signal or luminaire functions, the luminaire according to the invention has only a small space. The design possibilities of the luminaire can be extended considerably. In order to meet, for example, the color locus for the rear fog light function, the element is designed as a color filter and connected upstream of the light source. If the element is not upstream, then there is the reversing light function. Of course, other signal and / or lighting functions can be achieved with the luminaire according to the invention.

Bei einer Variante kann beispielsweise bei gleichbleibendem äußerem Erscheinungsbild durch die Verwendung eines speziellen Elementes ein Fahrtrichtungsanzeiger und/oder eine Veränderung der abgestrahlten Lichtwerte bei schlechten Umgebungsbedingungen erreicht werden.In one variant, for example, with a constant external appearance through the use of a special element, a direction indicator and / or a change in the radiated light values in poor environmental conditions can be achieved.

Werden als Leuchtmittel LEDs eingesetzt, die verschiedenfarbiges Licht abstrahlen, kann bei Verwendung entsprechender Elemente die Leuchte für alle benötigten Licht- und Signalfunktionen eingesetzt werden.If LEDs are used as light sources emitting different colored light, the light can be used for all required light and signal functions when using appropriate elements.

Vorteilhaft ist das verstellbare Element formstabil ausgebildet und wird mit einem entsprechenden Antrieb zwischen einer Außergebrauchsstellung und einer Gebrauchsstellung verstellt.Advantageously, the adjustable element is formed dimensionally stable and is adjusted with a corresponding drive between a non-use position and a use position.

Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further features of the invention will become apparent from the other claims, the description and the drawings.

Die Leuchte 1 gemäß den Fig. 1 bis 3 hat ein Gehäuse 2, von dem in den Fig. 1 bis 3 nur ein Teil dargestellt ist. Es hat wenigstens eine Lichtaustrittsöffnung 3, die durch eine Lichtscheibe 4 geschlossen ist. Sie ist am Gehäuse 2 in bekannter Weise befestigt, beispielsweise durch Schweißen oder Kleben. Die Lichtaustrittsöffnung 3 kann runden, eckigen oder jeden anderen geeigneten Umriss aufweisen.The lamp 1 according to the Fig. 1 to 3 has a housing 2 from which in the Fig. 1 to 3 only one part is shown. It has at least one light exit opening 3, which is closed by a lens 4. It is attached to the housing 2 in a known manner, for example by welding or gluing. The light exit opening 3 may have round, square or any other suitable outline.

Die Leuchte 1 hat eine Reflektorkammer 5, die durch einen Reflektor 6 und die Lichtscheibe 4 begrenzt wird. Der Reflektor 6 kann ein zusätzliches Bauteil sein, das in das Leuchtengehäuse 2 eingesetzt ist. Der Reflektor 6 kann aber auch Bestandteil des Gehäuses 2 sein, wie in den Fig. 1 und 2 dargestellt ist. Der Reflektor 6 ist auf seiner der Reflektorkammer 5 zugewandten Innenseite mit Optiken 7 versehen, die beispielsweise als Walzen- oder Kissenoptiken ausgebildet sein können.The luminaire 1 has a reflector chamber 5, which is bounded by a reflector 6 and the lens 4. The reflector 6 may be an additional component which is inserted into the luminaire housing 2. The reflector 6 may also be part of the housing 2, as in the Fig. 1 and 2 is shown. The reflector 6 is provided on its inside facing the reflector chamber 5 inside with optics 7, which may be formed, for example, as a roll or cushion optics.

Im Brennpunkt des Reflektors 6 befindet sich ein Leuchtmittel 8, das im Ausführungsbeispiel eine Glühlampe ist. Sie ist über einen Sockel 9 in einer Halterung 10 gehalten, die zentrisch im Reflektor 6 angeordnet ist. Die Halterung 10 steht über den Reflektor 6 nach außen vor. Am Leuchtmittelsockel 9 vorhandene elektrische Anschlüsse 11 stehen nach außen über die Halterung 10 vor, so dass eine einfache Kontaktierung des Leuchtmittels 8 möglich ist.In the focal point of the reflector 6 is a light source 8, which is an incandescent lamp in the embodiment. It is held by a base 9 in a holder 10, which is arranged centrally in the reflector 6. The holder 10 projects beyond the reflector 6 to the outside. On the lamp base 9 existing electrical connections 11 project outwardly beyond the holder 10, so that a simple contacting of the lamp 8 is possible.

Der Reflektor 6 ist im Bereich zwischen der Halterung 10 und der Lichtscheibe 4 mit einer Öffnung 12 versehen, in der eine Führung 13 für ein Filterelement 14 vorgesehen ist. Es ist etwa halbzylindrisch ausgebildet und um eine Achse 15 schwenkbar, die sich im Bereich der Halterung 10 bzw. des Leuchtmittelsockels 9 befindet. In Fig. 1 befindet sich das Filterelement 14 in seiner Außerbetriebsstellung. Das vom Leuchtmittel 8 abgestrahlte Licht wird teilweise direkt und teilweise über den Reflektor 7 zur Lichtscheibe 4 gelenkt, durch welche das Licht in Pfeilrichtung 16 nach außen tritt. Das Filterelement 14 ist so weit zurückgeschwenkt, dass es die Funktion des Reflektors 6 nicht beeinträchtigt.The reflector 6 is provided in the region between the holder 10 and the lens 4 with an opening 12 in which a guide 13 is provided for a filter element 14. It is approximately semi-cylindrical and pivotable about an axis 15, which is located in the region of the holder 10 and the illuminant base 9. In Fig. 1 is the filter element 14 in its inoperative position. The light emitted by the light source 8 is partially directed directly and partially via the reflector 7 to the lens 4, through which the light in the direction of arrow 16 passes to the outside. The filter element 14 is pivoted back so far that it does not affect the function of the reflector 6.

Mittels eines noch zu erläuternden Antriebes kann das Filterelement 14 um die Achse 15 in die Reflektorkammer 5 geschwenkt werden (Fig. 2), in der es mit Abstand das Leuchtmittel 8 umgibt. Die Reflektorkammer 5 hat, wie sich aus Fig. 3 ergibt, rechteckförmigen Umriss, entgegen Strahlrichtung 16 gesehen. Das Filterelement 14 hat eine solche Breite, dass es sich zwischen zwei die Reflektorkammer senkrecht zur Schwenkachse 15 begrenzenden Seitenwänden 17 und 18 erstreckt. Der Abstand zwischen den Seitenwänden 17, 18 und den Seitenrändern 19, 20 des Filterelementes 14 ist minimal, so dass nahezu kein Streulicht im Bereich zwischen den Seitenwänden 17, 18 und den Seitenrändern 19, 20 nach außen gelangen kann. Wie sich aus den Fig. 2 und 3 ergibt, erstreckt sich das Filterelement 14 in der Gebrauchslage gemäß Fig. 2 bis zum Reflektor 6 sowie bis zu gegebenenfalls auf der Reflektorfläche vorgesehenen Optiken 7. In der Gebrauchslage umgibt das Filterelement 14 das Leuchtmittel 8 mit Abstand. Das Filterelement 14 ist lichtdurchlässig ausgebildet, so dass das vom Leuchtmittel 8 abgestrahlte Licht durch die Lichtscheibe 4 nach außen treten kann.By means of a drive still to be explained, the filter element 14 can be pivoted about the axis 15 into the reflector chamber 5 ( Fig. 2 ), in which it surrounds the bulbs 8 at a distance. The reflector chamber 5 has, as is apparent Fig. 3 shows, rectangular outline, seen opposite to beam direction 16. The filter element 14 has a width such that it extends between two side walls 17 and 18 delimiting the reflector chamber perpendicular to the pivot axis 15. The distance between the side walls 17, 18 and the side edges 19, 20 of the filter element 14 is minimal, so that almost no stray light in the region between the side walls 17, 18 and the side edges 19, 20 can escape to the outside. As is clear from the Fig. 2 and 3 results, the filter element 14 extends in the position of use according to Fig. 2 up to the reflector 6 and up to optics optionally provided on the reflector surface 7. In the operating position, the filter element 14 surrounds the light emitting means 8 at a distance. The filter element 14 is transparent, so that the light emitted by the lamp 8 light can pass through the lens 4 to the outside.

Die Führung 13 für das Filterelement 14 ist so ausgebildet, dass es das Filterelement bei seiner Verstellung einwandfrei führt.The guide 13 for the filter element 14 is designed so that it performs the filter element properly in its adjustment.

Das Filterelement 14 ist ein Farbfilter, mit dem die Farbtemperatur des vom Leuchtmittel 8 abgestrahlten Lichtes verändert wird. Beispielhaft dient die Leuchte, wenn das Filterelement 14 die Außergebrauchslage gemäß Fig. 1 einnimmt, als Rückfahrleuchte. Mit der beschriebenen Ausbildung ist es möglich, die Leuchte mit derselben Reflektorkammer 5 auch als Nebelschlussleuchte zu verwenden. Die Lichtverteilung (Lichtwerte) für eine Nebelschlussleuchte und eine Rückfahrleuchte überschneiden sich in der Regel. Soll nun die Leuchte 1 als Nebelschlussleuchte wirksam sein, wird das Filterelement 14 in die Gebrauchslage gemäß Fig. 2 geschwenkt. Da das Filterelement 14 als Farbfilter ausgebildet ist, wird das vom Leuchtmittel 8 abgestrahlte Licht in seiner Farbtemperatur so geändert, dass es die gesetzlichen Anforderungen hinsichtlich der Funktion einer Nebelschlussleuchte erfüllt. Auf diese Weise können zumindest zwei Signalfunktionen, beispielsweise die Nebelschlusslicht- und die Rückfahrlichtfunktion, in einer einzigen Reflektorkammer 5 realisiert werden. Die Leuchte 1 kann dadurch sehr kompakt ausgebildet sein.The filter element 14 is a color filter with which the color temperature of the light emitted by the light source 8 is changed. By way of example, the lamp is used when the filter element 14 according to the non-use position Fig. 1 occupies, as a reversing light. With the described embodiment, it is possible, the lamp with the same reflector chamber 5 as a rear fog lamp to use. The light distribution (light values) for a rear fog lamp and a reversing light usually overlap. If now the lamp 1 to be effective as a rear fog lamp, the filter element 14 is in accordance with the position of use Fig. 2 pivoted. Since the filter element 14 is designed as a color filter, the light emitted by the lamp 8 light is changed in its color temperature so that it meets the legal requirements regarding the function of a rear fog lamp. In this way, at least two signal functions, for example the rear fog light function and the reversing light function, can be realized in a single reflector chamber 5. The lamp 1 can be made very compact.

Je nach Ausbildung des Filterelementes 14 kann die Leuchte 1 auch andere und/oder weitere Signalfunktionen mit nur einer einzigen Reflektorkammer 5 verwirklichen. Je nach Ausbildung der Leuchte 1 kann das Filterelement 14 auch eine andere Formgestaltung haben. Wesentlich ist, dass das Filterelement 14 so zwischen das Leuchtmittel 8 und die Lichtscheibe 4 verstellt werden kann, dass die unterschiedlichen Signalfunktionen der Leuchte 1 erreicht werden.Depending on the design of the filter element 14, the lamp 1 can also realize other and / or further signal functions with only a single reflector chamber 5. Depending on the design of the lamp 1, the filter element 14 may also have a different shape design. It is essential that the filter element 14 can be adjusted between the lamp 8 and the lens 4 so that the different signal functions of the lamp 1 can be achieved.

In der Grundeinstellung der Leuchte 1 kann das Filterelement 14 die Gebrauchslage gemäß Fig. 2 einnehmen. Wird der Rückwärtsgang eingelegt, muss das Filterelement 14 in die Außergebrauchslage gemäß Fig. 1 verstellt werden. Es ist aber auch möglich, dass in der Grundeinstellung das Filterelement 14 die Außergebrauchslage gemäß Fig. 1 einnimmt. In diesem Falle wird das Filterelement 14 dann in die Gebrauchslage verstellt, wenn die Nebelschlussleuchten des Fahrzeuges eingeschaltet werden.In the basic setting of the lamp 1, the filter element 14 according to the position of use Fig. 2 taking. If the reverse gear is engaged, the filter element 14 must be in the non-use position according to Fig. 1 be adjusted. But it is also possible that the filter element 14 in the default setting according to the use-out position Fig. 1 occupies. In this case, the filter element 14 is then adjusted to the position of use when the rear fog lamps of the vehicle are turned on.

Die Verstellung des Filterelementes 14 zwischen der Gebrauchs- und der Außergebrauchslage kann auf verschiedene Weise erfolgen. So kann zum Verstellen des Filterelementes 14 beispielsweise ein Elektromotor, ein Hubmagnet, ein Bimetall, ein Memorymetall oder dergleichen vorgesehen sein.The adjustment of the filter element 14 between the use and the use-out position can be done in various ways. For example, an electric motor, a lifting magnet, a bimetal, a memory metal or the like may be provided for adjusting the filter element 14.

Fig. 3 zeigt beispielhaft einen motorischen Antrieb zur Verstellung des Filterelementes 14. Auf der Achse 15 sitzt außerhalb der Leuchte 1 ein Zahnrad 21, das mit einem Ritzel 22 eines Elektromotors 23 in Eingriff ist. Er kann klein und kompakt gebaut sein, da zum Verstellen des Filterelementes 14 keine großen Antriebsmomente notwendig sind. Der Elektromotor 23 kann darum platzsparend unmittelbar an der Seitenwand 17 oder 18 des Gehäuses 2 vorgesehen sein. Es ist möglich, den Elektromotor 23 unmittelbar an der Seitenwand 17/18 des Gehäuses 2 zu befestigen. Es ist grundsätzlich aber auch möglich, den Elektromotor 23 gesondert im Einbauraum des Kraftfahrzeuges einzubauen. Fig. 3 shows an example of a motor drive for adjusting the filter element 14. On the axis 15 sits outside the lamp 1, a gear 21 which is in engagement with a pinion 22 of an electric motor 23. It can be made small and compact, since no large drive torques are necessary for adjusting the filter element 14. The electric motor 23 can therefore be provided to save space directly on the side wall 17 or 18 of the housing 2. It is possible to fix the electric motor 23 directly to the side wall 17/18 of the housing 2. In principle, however, it is also possible to install the electric motor 23 separately in the installation space of the motor vehicle.

Während bei der beschriebenen Ausführungsform das Filterelement 14 formstabil ausgebildet ist, wird es beim Ausführungsbeispiel nach Fig. 4 durch eine Folie gebildet. An die Führung 13 im Reflektor 6 schließt eine teilzylindrische Führung 24 an, die zwei parallel zueinander liegende, teilkreisförmig gekrümmte Führungsschalen 25 und 26 aufweist. Sie umgeben das Leuchtmittel 8 mit Abstand und erstrecken sich von der Führung 13 bis zur Reflektorinnenfläche auf der anderen Seite des Leuchtmittels 8. Das folienartige Filterelement 14 ist im übrigen so an den Antrieb gekoppelt, dass es nicht nur aus der Gebrauchslage gemäß Fig. 4 zurückgezogen, sondern auch in die Gebrauchslage gemäß Fig. 4 verschoben werden kann. Das folienförmige Filterelement 14 wird auf eine Trommel 27 aufgewickelt, die drehfest auf einer Motorwelle 28 des Elektromotors 23 sitzt. Die Trommel 27 ist so ausgebildet, dass das Filterelement 14 zuverlässig aufgewickelt und auch zuverlässig in die Führung 13 gelangt. Um eine Beschädigung des Filterelementes 14 beim Eintritt in die Führung 13 zu vermeiden, ist das Eintrittsende 29 der Führung 13 vorteilhaft bogenförmig aufgeweitet. Damit das Filterelement 14 nicht vollständig aus der Führung 24 gezogen werden kann, ist am Eintrittsende 29 der Führung 13 ein (nicht dargestellter) Anschlag vorgesehen, an dem das freie Ende 30 bzw. ein dort vorgesehener Gegenanschlag zur Anlage kommt.While in the described embodiment, the filter element 14 is formed dimensionally stable, it is in the embodiment after Fig. 4 formed by a foil. To the guide 13 in the reflector 6 includes a part-cylindrical guide 24 which has two mutually parallel, part-circular curved guide shells 25 and 26. They surround the luminous means 8 at a distance and extend from the guide 13 to the reflector inner surface on the other side of the luminous means 8. The film-like filter element 14 is otherwise coupled to the drive that it not only from the position of use Fig. 4 withdrawn, but also in the position of use according to Fig. 4 can be moved. The film-shaped filter element 14 is wound onto a drum 27 which is non-rotatably mounted on a motor shaft 28 of the electric motor 23. The drum 27 is designed so that the filter element 14 reliably wound and also reliably enters the guide 13. In order to avoid damage to the filter element 14 when entering the guide 13, the inlet end 29 of the guide 13 is advantageously widened arcuate. So that the filter element 14 can not be pulled completely out of the guide 24, a stop (not shown) is provided at the entry end 29 of the guide 13, on which the free end 30 or a counter-stop provided there comes to rest.

Das Filterelement 14 kann auch so ausgebildet sein, dass es flexibel ausgebildet ist, in Verschieberichtung jedoch eine solche Formsteifigkeit hat, dass es sowohl in die Gebrauchslage geschoben als auch in die Außergebrauchslage gezogen werden kann.The filter element 14 may also be designed so that it is flexible, but in the displacement direction has such a stiffness that it can be pushed into both the position of use and pulled into the use position.

Wie anhand der vorigen Ausführungsform erläutert worden ist, wird das Filterelement 14 je nach gewünschter Signalfunktion in die Gebrauchslage gemäß Fig. 4 geschoben oder aus ihr in die Außergebrauchslage zurückgezogen. Die Führungsschalen 25, 26 der Führung 24 sind selbstverständlich für das vom Leuchtmittel 8 ausgesandte Licht durchlässig. Das folienförmige Filterelement 14 hat nur sehr geringes Gewicht, so dass es bei Bedarf rasch in die jeweiligen Lagen verstellt werden kann. Insbesondere sind zur Verstellung des Filterelementes 14 keine aufwendigen Elektromotoren 23 oder sonstige Antriebe notwendig, die zudem sehr kompakt ausgebildet sein können.As has been explained with reference to the previous embodiment, the filter element 14 is according to the desired signal function in the position of use according to Fig. 4 pushed or withdrawn from it in the use position. The guide shells 25, 26 of the guide 24 are of course permeable to the light emitted by the lamp 8 light. The film-shaped filter element 14 has only a very low weight, so that it can be adjusted quickly if necessary in the respective layers. In particular, no complicated electric motors 23 or other drives are necessary for adjusting the filter element 14, which can also be made very compact.

Die Leuchte 1 gemäß Fig. 4 ist im Übrigen gleich ausgebildet wie das vorige Ausführungsbeispiel gemäß den Fig. 1 bis 3.The luminaire 1 according to Fig. 4 is otherwise the same design as the previous embodiment according to the Fig. 1 to 3 ,

Fig. 5 zeigt eine Leuchte 1, bei der das Filterelement ständig zwischen dem Leuchtmittel 8 und der Lichtscheibe 4 innerhalb der Reflektorkammer 5 angeordnet ist. Das Filterelement befindet sich mit geringem Abstand unterhalb der Lichtscheibe 4 in der Reflektorkammer 5. Das Filterelement 14 hat mit Abstand nebeneinander liegende Lamellen 30, die in halber Länge um jeweils eine Achse 31 schwenkbar gelagert sind. Die Schwenkachsen 31 sind in (nicht dargestellten) Seitenwänden gelagert, die in der Reflektorkammer 5 in geeigneter Weise befestigt sind. Die Lamellen 30 sind an ihren von der Lichtscheibe 4 abgewandten Enden an ein Verstellelement 32 angelenkt, über das die Lamellen 30 gleichzeitig und in gleichem Maße verschwenkt werden können. Das Verstellelement 32 ist an einen zweiarmigen Hebel 33 angelenkt, der durch die Öffnung 12 im Reflektor 6 in die Reflektorkammer 5 ragt. Die Schwenkachse 34 des Hebels 33 liegt vorteilhaft innerhalb der Querschnittsdicke des Reflektors 6. An das außerhalb der Reflektorkammer 5 liegende freie Ende des Hebels 34 ist eine Schubstange 35 angelenkt, die Teil eines Aktuators 36, vorzugsweise eines Magnetstellers, ist. Er ist vorteilhaft am Gehäuse 2 der Leuchte 1 befestigt, vorzugsweise angeschweißt oder angeklebt. Fig. 5 shows a lamp 1, in which the filter element is arranged continuously between the lamp 8 and the lens 4 within the reflector chamber 5. The filter element is located at a small distance below the lens 4 in the reflector chamber 5. The filter element 14 has spaced apart lamellae 30, which are mounted in the half-length about one axis 31 pivotally. The pivot axes 31 are mounted in (not shown) side walls which are secured in the reflector chamber 5 in a suitable manner. The fins 30 are hinged at their ends facing away from the lens 4 to an adjusting element 32, via which the fins 30 can be pivoted simultaneously and to the same extent. The adjusting element 32 is articulated to a two-armed lever 33 which projects through the opening 12 in the reflector 6 in the reflector chamber 5. The pivot axis 34 of the lever 33 is advantageously within the cross-sectional thickness of the reflector 6. At the outside of the reflector chamber 5 lying free end of the lever 34 is a push rod 35 hinged, which is part of an actuator 36, preferably a magnetic actuator. It is advantageously attached to the housing 2 of the lamp 1, preferably welded or glued.

In der in Fig. 5 dargestellten Lage der Schubstange 35 bzw. des Hebels 33 liegen die Lamellen 30 des Filterelementes 14 in Strahlrichtung 16, so dass das vom Leuchtmittel 8 ausgesandte und zum Teil am Reflektor 6 reflektierte Licht ungehindert durch die Lichtscheibe 4 nach außen treten kann. Die Lamellen 30 können mittels des Aktuators 36 in die mit strichpunktierten Linien angedeutete Lage geschwenkt werden, in der die Lamellen 30 aneinanderliegen und somit eine geschlossene Filterfläche bilden. Die Lamellen 30 sind wiederum so eingefärbt, dass in dieser Gebrauchslage das aus der Leuchte 1 austretende Licht die für diese Funktion notwendige Farbtemperatur hat.In the in Fig. 5 shown position of the push rod 35 and the lever 33 are the fins 30 of the filter element 14 in the beam direction 16, so that the light emitted by the lamp 8 and reflected in part on the reflector 6 light can pass through the lens 4 unhindered outward. The slats 30 can be pivoted by means of the actuator 36 in the direction indicated by dash-dotted lines position in which the slats 30 abut each other and thus form a closed filter surface. The lamellae 30 are in turn so colored that in this position of use the light emerging from the luminaire 1 has the color temperature necessary for this function.

Die Schwenkachsen 31 der Lamellen 30 sind vorteilhaft der Krümmung der Lichtscheibe 4 angepasst, so dass alle Lamellen 30 gleiche Breite haben können und dadurch sichergestellt ist, dass sie in der mit ausgezogenen Linien dargestellten Lage die Innenseite der Lichtscheibe 4 allenfalls berühren, vorteilhaft geringen Abstand von ihr haben. Werden die Lamellen 30 in die andere Lage um etwa 90° geschwenkt, dann bilden sie eine durchgehend geschlossene Filterfläche, die etwa parallel zur Innenseite der Lichtscheibe 4 liegt. Um diese geschlossene Filterfläche zu erreichen, wird die Schubstange 35 ausgefahren, wodurch der Hebel 33 um die Achse 34 im Uhrzeigersinn geschwenkt wird. Das stangenförmige Verstellelement 32 wird dementsprechend in Fig. 5 nach rechts verschoben, wodurch die Lamellen 30 in die mit strichpunktierten Linien angedeutete Lage verschwenkt werden. Da die Lamellen 30 an das Verstellelement 32 angelenkt sind, werden die Lamellen 30 innerhalb kurzer Zeit gleichzeitig in die jeweilige Lage geschwenkt. Je nach Länge der Lamellen 30 können auch weitere Verstellelemente 32 vorgesehen sein, um die Lamellen 30 zuverlässig und verkantungsfrei um ihre Achsen 31 zu schwenken.The pivot axes 31 of the blades 30 are advantageously adapted to the curvature of the lens 4, so that all blades 30 may have the same width and is thereby ensured that they touch the inside of the lens 4 at best in the position shown in solid lines, advantageously small distance from you have. If the slats 30 are pivoted into the other position by about 90 °, then they form a continuous closed filter surface which is approximately parallel to the inside of the lens 4. To achieve this closed filter surface, the push rod 35 is extended, whereby the lever 33 is pivoted about the axis 34 in a clockwise direction. The rod-shaped adjusting element 32 is accordingly in Fig. 5 shifted to the right, causing the slats 30 are pivoted in the direction indicated by dash-dotted lines position. Since the fins 30 are hinged to the adjusting element 32, the fins 30 are pivoted simultaneously within a short time in the respective position. Depending on the length of the slats 30, further adjusting elements 32 may be provided in order to pivot the slats 30 reliably and without jamming about their axes 31.

Die Lamellen 30 sind in einem solchen Bereich vorgesehen, dass sie bei geschlossener Filterfläche die entsprechende Leuchtfunktion erfüllen können.The fins 30 are provided in such a range that they can fulfill the corresponding lighting function when the filter surface is closed.

Die Hebelübersetzungen sind so gewählt, dass der zweiarmige Hebel 33 nur um ein geringes Maß geschwenkt werden muss, um die Lamellen 30 aus ihrer parallel zur Strahlrichtung 16 liegenden Lage in die Gebrauchslage zur Bildung der geschlossenen Filterfläche zu verschwenken. Dadurch muss die Öffnung 12 im Reflektor 7 auch nicht sehr groß sein. Der in die Reflektorkammer 5 ragende Teil des Hebels 33 beeinträchtigt die Leuchtfunktion der Leuchte 1 nicht.The lever ratios are selected so that the two-armed lever 33 only has to be pivoted by a small amount in order to pivot the slats 30 from their lying parallel to the beam direction 16 position in the operating position to form the closed filter surface. As a result, the opening 12 in the reflector 7 also does not have to be very large. The protruding into the reflector chamber 5 part of the lever 33 does not affect the lighting function of the lamp 1.

Im Unterschied zu den vorigen Ausführungsbeispielen können die Lamellen 30 auch in jede Zwischenlage geschwenkt werden, wodurch sich weitere Signalfunktionen der Leuchte 1 sehr einfach erzeugen lassen. Die Leuchte 1 ist im übrigen gleich ausgebildet wie die vorigen Ausführungsbeispiele.In contrast to the previous embodiments, the slats 30 can also be pivoted in each intermediate position, which can be more easily generate signal functions of the lamp 1. The lamp 1 is otherwise the same design as the previous embodiments.

Bei der Leuchte gemäß Fig. 6 wird zur Erzielung der unterschiedlichen Signalfunktionen das Leuchtmittel 8 innerhalb der Reflektorkammer 5 verstellt. Im Unterschied zur vorigen Ausführungsform wird das Leuchtmittel 8 durch eine LED gebildet, die auf einer Platine 37 sitzt. Das Leuchtmittel 8 sitzt wiederum im Brennpunkt des Reflektors 6. Die Platine 37 mit der LED 8 ist um eine Achse 38 schwenkbar, die im Brennpunkt des Reflektors 6 liegt.In the light according to Fig. 6 is the illumination means 8 adjusted within the reflector chamber 5 to achieve the different signal functions. In contrast to the previous embodiment, the light-emitting means 8 is formed by an LED which sits on a circuit board 37. The light-emitting means 8 again sits in the focal point of the reflector 6. The circuit board 37 with the LED 8 is pivotable about an axis 38 which lies in the focal point of the reflector 6.

Die Lichtscheibe 4 besteht beispielhaft aus zwei unterschiedlichen Lichtscheibenbereichen 39 und 40, die im Ausführungsbeispiel gleich groß sind.The lens 4 is exemplified by two different lens areas 39 and 40, which are the same size in the embodiment.

In der in Fig. 6 dargestellten Lage des Leuchtmittels 8 bzw. der Platine 37 wird das Licht vom Reflektor 6 in Richtung auf den Lichtscheibenbereich 39 reflektiert, durch den die Lichtstrahlen parallel zueinander nach außen treten. Die Platine 37 befindet sich in dieser Lage senkrecht zur Lichtscheibe 4 und in Höhe der Trennfuge zwischen den beiden Lichtscheibenbereichen 39, 40. Die Platine 37 kann um die Achse 38 um 180° geschwenkt werden, so dass das von der LED 8 abgestrahlte Licht über den Reflektor 6 nunmehr ausschließlich dem Lichtscheibenbereich 40 zugeführt wird. Die beiden Lichtscheibenbereiche 39 und 40 bilden Filterelemente, mit denen unterschiedliche Signalfunktionen bzw. Leuchtfunktionen der Leuchte 1 eingestellt werden können. So kann beispielhaft dem Lichtscheibenbereich 39 die Funktion einer Nebelschlussleuchte und dem Lichtscheibenbereich 30 die Funktion eines Rückfahrlichtes zugeordnet werden. Je nach gewünschter Funktion der Leuchte 1 können den Lichtscheibenbereich 39, 40 auch andere Signal- bzw. Leuchtfunktionen zugeordnet werden.In the in Fig. 6 shown position of the light bulb 8 and the board 37, the light from the reflector 6 is reflected in the direction of the light disk portion 39 through which the light rays parallel to each other outward. The board 37 is located in this position perpendicular to the lens 4 and at the level of the parting line between the two lens areas 39, 40. The board 37 can be pivoted about the axis 38 by 180 °, so that the radiated light from the LED 8 on the Reflector 6 now is supplied exclusively to the light disk area 40. The two light disk areas 39 and 40 form filter elements with which different signal functions or lighting functions of the lamp 1 can be set. Thus, by way of example, the function of a rear fog lamp can be assigned to the light disk region 39, and the function of a reversing light to the light disk region 30. Depending on the desired function of the lamp 1, the light disk area 39, 40 can also be assigned other signal or lighting functions.

Die Schwenkachse 38 ist aus der Reflektorkammer 5 bzw. der Leuchte 1 herausgeführt und an einen Antrieb angeschlossen, mit dem die Achse 38 in die gewünschte Richtung gedreht werden kann.The pivot axis 38 is led out of the reflector chamber 5 or the lamp 1 and connected to a drive, with which the axis 38 can be rotated in the desired direction.

Die Lichtscheibe 4 kann auch aus mehr als zwei Lichtscheibenbereichen bestehen, so dass noch weitere Signal- bzw. Leuchtfunktionen erzielt werden können. In diesem Falle wird die Platine 37 mit der LED 8 in entsprechend unterschiedliche Positionen um die Achse 38 gedreht.The lens 4 may also consist of more than two lens areas, so that even more signal or lighting functions can be achieved. In this case, the board 37 is rotated with the LED 8 in correspondingly different positions about the axis 38.

Da die LED 8 nur wenig Einbauraum benötigt, kann die Leuchte 1 sehr kompakt und insbesondere flach gebaut werden. Wie bei den vorigen Ausführungsformen wird für die unterschiedlichen Funktionen nur eine Reflektorkammer 5 benötigt.Since the LED 8 requires little installation space, the lamp 1 can be very compact and built in particular flat. As in the previous embodiments, only one reflector chamber 5 is required for the different functions.

Beim Ausführungsbeispiel nach Fig. 7 kann wiederum zwischen dem Reflektor 6 und der Lichtscheibe 4 das Filterelement 14 eingeschwenkt werden. Der Reflektor 6 hat eine zentrale Öffnung 41, in der die Platine 37 mit dem Leuchtmittel 8 liegt, das eine LED ist. Sie liegt im Brennpunkt des Reflektors 6. Die Platine 37 schließt die Öffnung 41 im Reflektor 6 vollständig, so dass rückseitiges Streulicht vermieden wird. Der Reflektor 6 kann Teil des Leuchtengehäuses sein, aber auch, wie in Fig. 7 dargestellt, ein vom Leuchtengehäuse gesondertes Bauteil sein. Der Reflektor 6 hat geringen Abstand von der Lichtscheibe 4, so dass das Filterelement 14 zuverlässig in den Zwischenraum zwischen dem Reflektor 6 und der Lichtscheibe 4 geschwenkt werden kann. Die Lichtscheibe 4 ist beispielhaft über ihre Länge gekrümmt. Das Filterelement 14 verläuft parallel zur Innenseite der Lichtscheibe 4.According to the embodiment Fig. 7 In turn, between the reflector 6 and the lens 4, the filter element 14 can be pivoted. The reflector 6 has a central opening 41 in which the circuit board 37 is located with the lamp 8, which is an LED. It lies in the focal point of the reflector 6. The circuit board 37 closes the opening 41 in the reflector 6 completely, so that back-scattered light is avoided. The reflector 6 may be part of the lamp housing, but also, as in Fig. 7 shown to be a separate from the luminaire housing component. The reflector 6 has a small distance from the lens 4, so that the filter element 14 reliably pivoted into the space between the reflector 6 and the lens 4 can be. The lens 4 is curved by way of example over its length. The filter element 14 runs parallel to the inside of the lens 4.

Das Filterelement 14 ist an zwei Trägern 42 befestigt, von denen in Fig. 7 ein Träger dargestellt ist. Die Träger 42 sind kreissektorförmig ausgebildet und um eine Achse 43 schwenkbar. Die Länge des Filterelementes 14 entspricht vorteilhaft der maximalen Breite der Träger 42, die durch das Filterelement 14 miteinander verbunden sind. Der Reflektor 6 befindet sich im Bereich zwischen den beiden Trägern 42. Die Schwenkachse 43 wird durch einen Antrieb 44 angetrieben, der im Gehäuse 2 oder auch außerhalb des Gehäuses 2 angeordnet sein kann. Mit dem Antrieb 44 lässt sich das Filterelement 14 in Richtung des Doppelpfeiles 45 in die gewünschte Richtung verstellen.The filter element 14 is attached to two supports 42, of which in Fig. 7 a carrier is shown. The carrier 42 are formed in a sector of a circle and pivotable about an axis 43. The length of the filter element 14 advantageously corresponds to the maximum width of the carrier 42, which are interconnected by the filter element 14. The reflector 6 is located in the region between the two supports 42. The pivot axis 43 is driven by a drive 44, which may be arranged in the housing 2 or outside of the housing 2. With the drive 44, the filter element 14 can be adjusted in the direction of the double arrow 45 in the desired direction.

Die von der LED 8 ausgesandten Strahlen werden am Reflektor 6 parallel zueinander reflektiert, die in Strahlrichtung 16 durch die Lichtscheibe 4 nach außen treten. Je nach gewünschter Signal/Leuchtfunktion wird das Filterelement 14 in die Gebrauchslage gemäß Fig. 7 oder in die Außergebrauchslage verstellt, in der sich das Filterelement 14 außerhalb des Bereiches zwischen dem Reflektor 6 und der Lichtscheibe 4 befindet.The emitted by the LED 8 beams are reflected parallel to each other at the reflector 6, which pass in the beam direction 16 through the lens 4 to the outside. Depending on the desired signal / light function, the filter element 14 in accordance with the position of use Fig. 7 or adjusted in the non-use position in which the filter element 14 is outside the range between the reflector 6 and the lens 4.

Im dargestellten und beschriebenen Ausführungsbeispiel befindet sich zwischen den Trägern 42 nur ein einziger Reflektor 6. Die Träger 42 können senkrecht zur Zeichenebene auch einen größeren Abstand voneinander haben, so dass beispielsweise auch zwei oder mehr Reflektoren 6 hintereinander angeordnet sein können.In the illustrated and described embodiment, only a single reflector 6 is located between the carriers 42. The carriers 42 may also be at a greater distance from each other perpendicular to the plane of the drawing so that, for example, two or more reflectors 6 can be arranged one behind the other.

Fig. 8 zeigt eine Ausführungsform, bei der nicht das Filterelement, sondern das Leuchtmittel 8 relativ zum Filterelement verstellt wird. Im Ausführungsbeispiel ist das Leuchtmittel 8 eine LED, die auf der Platine 37 sitzt. Von der Platine 37 steht quer ein Stift 46 ab, der durch ein Langloch 47 eines Hebels 48 ragt. Er sitzt mit einem Ende auf einer Achse 49 eines Antriebes 50, der vorteilhaft ein Elektromotor ist. Er kann im Gehäuse der Leuchte, aber auch außerhalb des Leuchtengehäuses montiert sein. Fig. 8 shows an embodiment in which not the filter element, but the lighting means 8 is adjusted relative to the filter element. In the exemplary embodiment, the lighting means 8 is an LED which sits on the circuit board 37. From the board 37 is transverse to a pin 46 which projects through a slot 47 of a lever 48.

Das Leuchtmittel 8 und der Stift 46 liegen zwischen den beiden Führungsschenkeln 52, 53 der Führung 51.The circuit board 37 is linearly displaceable in a guide 51. It is formed by a C-shaped rail in which the board 37 is slidably guided with their longitudinal sides. The light source 8 and the pin 46 are between the two guide legs 52, 53 of the guide 51st

Die Breite des Langloches 47 im Hebel 48 entspricht dem Durchmesser des Stiftes 46, so dass dieser im Langloch beim Verschieben der Platine 37 einwandfrei geführt werden kann. Je nach Drehrichtung 54 der Schwenkachse 49 wird der Hebel 48 geschwenkt. Über den Stift 46 wird hierbei die Platine 37 in der Führung 51 nach oben oder unten verschoben, je nach Schwenkrichtung des Hebels 48. Das Langloch 47 hat eine solche Länge, dass die Platine 37 mit ihrem Leuchtmittel 8 im erforderlichen Maße verschoben werden kann.The width of the slot 47 in the lever 48 corresponds to the diameter of the pin 46, so that it can be performed properly in the slot when moving the board 37. Depending on the direction of rotation 54 of the pivot axis 49, the lever 48 is pivoted. Via the pin 46 in this case the board 37 is moved in the guide 51 up or down, depending on the pivoting direction of the lever 48. The slot 47 has a length such that the board 37 can be moved with its bulb 8 to the required extent.

Vor der (nicht dargestellten) Lichtscheibe befinden sich zwei unterschiedliche Filterelemente 14, 14', denen unterschiedliche Signal/Leuchtfunktionen zugeordnet sind. Je nachdem, welche Leucht/Signalfunktion für die Leuchte benötigt wird, wird die Platine 37 mit dem Leuchtmittel 8 so verschoben, dass das Licht entweder durch das Filterelement 14 oder das Filterelement 14' hindurchtritt. Die Lichtstrahlen haben entsprechend den vorhergehenden Ausführungsformen die Strahlrichtung 16.In front of the (not shown) lens are two different filter elements 14, 14 ', which are assigned to different signal / lighting functions. Depending on which light / signal function is required for the luminaire, the circuit board 37 is shifted with the luminous means 8 so that the light passes either through the filter element 14 or the filter element 14 '. The light beams have the beam direction 16 according to the preceding embodiments.

Der beschriebene Linearantrieb für das Leuchtmittel 8 ist nur beispielhaft zu verstehen. Es kann selbstverständlich jede Art von Linearantrieb eingesetzt werden.The described linear drive for the light-emitting means 8 is only to be understood as an example. Of course, any type of linear drive can be used.

Bei sämtlichen Ausführungsformen können wenigstens zwei Signal- und/ oder Leuchtfunktionen in einer einzigen Reflektorkammer 5 realisiert werden. Das Filterelement 14 und/oder die Lichtscheibe 4 können eingefärbt sein, so dass die gewünschte Signal- und/oder Leuchtenfunktion erreicht wird. Zusätzlich oder anstelle der Einfärbung können das Filterelement 14 und/oder die Lichtscheibe 4 auch entsprechende Optiken aufweisen, um die Signal- und/oder Leuchtenfunktion zu gewährleisten. Die Leuchte kann eine Heckleuchte eines Kraftfahrzeuges sein, lässt sich aber auch für jede andere Art von Leuchten einsetzen. Das Leuchtmittel 8 im Reflektor 6 kann in der beschriebenen Weise eine Glühlampe oder eine LED sein. Darüber hinaus kann das Leuchtmittel 8 auch jede andere Art eines lichtemittierenden Elementes sein. Auch ist es möglich, im Reflektor 6 nicht nur ein Leuchtmittel, sondern weitere Leuchtmittel vorzusehen. Dabei kann nur eine Art von Leuchtmittel, aber auch eine Mischung unterschiedlicher Arten von Leuchtmitteln vorgesehen sein. Schließlich ist es auch möglich, nicht nur das Filterelement 14 oder das Leuchtmittel 8 zu verstellen, sondern auch beide Elemente in einer Leuchte verstellbar auszubilden, so dass gleichzeitig das Leuchtmittel 8 und das Filterelement 14 verstellt werden können.In all embodiments, at least two signal and / or lighting functions can be realized in a single reflector chamber 5. The filter element 14 and / or the lens 4 may be colored, so that the desired signal and / or luminaire function is achieved becomes. In addition to or instead of coloring, the filter element 14 and / or the lens 4 may also have corresponding optics to ensure the signal and / or luminaire function. The lamp may be a tail lamp of a motor vehicle, but can also be used for any other type of lights. The light source 8 in the reflector 6 may be an incandescent lamp or an LED in the manner described. In addition, the lighting means 8 may be any other type of light-emitting element. It is also possible to provide not only a lighting means in the reflector 6, but further lighting means. In this case, only one type of lighting means, but also a mixture of different types of lighting means may be provided. Finally, it is also possible not only to adjust the filter element 14 or the light source 8, but also to make both elements adjustably adjustable in a luminaire, so that at the same time the light source 8 and the filter element 14 can be adjusted.

Bei entsprechender Gestaltung der Leuchte 1 ist es auch möglich, keinen Reflektor zu verwenden, sondern das Licht über Optiken und dergleichen der Lichtscheibe 4 zuzuführen.With an appropriate design of the lamp 1, it is also possible not to use a reflector, but to supply the light via optics and the like of the lens 4.
