Bei der erfindungsgemäßen Leuchte befindet sich demnach zwischen dem Leuchtmittel und der äußeren, das Gehäuse abschließenden Lichtscheibe die innere Lichtscheibe, welche wenigstens einen streifenförmigen Lichtdurchlassbereich hat, der eine Linsenstruktur aufweist. Das vom Leuchtmittel abgestrahlte Licht trifft rückseitig auf die innere Lichtscheibe und wird durch die Linsenstruktur des streifenförmigen Lichtdurchlassbereiches zur äußeren Lichtscheibe gelenkt. Die Linsenstruktur erweckt infolge der streifenförmigen Gestaltung des Lichtdurchlassbereiches den Eindruck eines Lichtleiters bzw. verstärkt einen solchen Eindruck.Accordingly, in the case of the luminaire according to the invention, the inner lens, which is at least one strip-shaped one, is located between the luminous means and the outer lens, which terminates the housing Has light transmission area, which has a lens structure. The light emitted by the light source hits the rear of the inner lens and is guided by the lens structure of the strip-shaped light transmission area to the outer lens.

Bei einer konkaven Ausführung kann die dem Leuchtmittel zugewandte, konkav gekrümmte Seite einen größeren Krümmungsradius aufweisen, als die gegenüberliegende Seite der Linsenstruktur der inneren Lichtscheibe.In a concave design, the concave-curved side facing the illuminant may have a larger radius of curvature than the opposite side of the lens structure of the inner lens.
Ebenfalls ist denkbar, dass die dem Leuchtmittel zugewandte, konkav gekrümmte Seite einen kleineren Krümmungsradius aufweist als die gegenüberliegende Seite der Linsenstruktur der inneren Lichtscheibe.It is likewise conceivable that the concave curved side facing the luminous means has a smaller radius of curvature than the opposite side of the lens structure of the inner lens.
Der Lichtdurchlassbereich erstreckt sich vorzugsweise über die Länge der inneren Lichtscheibe.The light transmission area preferably extends over the length of the inner lens.
Vorzugsweise ist der Lichtdurchlassbereich in wenigstens zwei mit Abstand nebeneinander liegende Segmente unterteilt.Preferably, the light passage area is divided into at least two spaced-apart segments.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung besteht die innere Lichtscheibe aus wenigstens zwei Schichten, zumindest einer äußeren und einer inneren Schicht.According to an advantageous embodiment of the invention, the inner lens of at least two layers, at least one outer and one inner layer.
Vorzugsweise bedeckt die äußere Schicht die innere Schicht der inneren Lichtscheibe vollständig.Preferably, the outer layer completely covers the inner layer of the inner lens.
Die beiden Schichten können beispielsweise durch Spritzgießen hergestellt sein.The two layers can be produced for example by injection molding.
Vorzugsweise bestehen die beiden Schichten aus gleichem Material. Ebenso ist denkbar, dass die beiden Schichten aus unterschiedlichen Materialien bestehen. Vorzugsweise weist die innere Schicht die Linsenstruktur auf.Preferably, the two layers of the same material. It is also conceivable that the two layers consist of different materials. Preferably, the inner layer has the lens structure.
Die innere Lichtscheibe mit der Linsenstruktur ist vorteilhaft einstückig, beispielsweise in einem Mehrschichtspritzverfahren, hergestellt. Dadurch können mehrere Bauteile funktionell in der inneren Lichtscheibe zusammengefasst werden. Die innere Lichtscheibe lässt sich dadurch kostengünstig und mit geringem technischem Aufwand herstellen. Die Montage der Leuchte ist einfach und damit kostengünstig durchzuführen.The inner lens with the lens structure is advantageously made in one piece, for example in a multi-layer molding process. As a result, several components can be functionally combined in the inner lens. The inner lens can be produced inexpensively and with little technical effort. The installation of the lamp is simple and therefore inexpensive to perform.
Die Linsenstruktur kann über die äußere Schicht vorstehen. Dabei kann die äußere Schicht im Bereich der Linsenstruktur unterbrochen sein.The lens structure may protrude beyond the outer layer. In this case, the outer layer may be interrupted in the region of the lens structure.
Eine besonders vorteilhafte Ausgestaltung der Erfindung sieht vor, dass die innere Schicht im Bereich neben dem Lichtdurchlassbereich bzw. bei mehreren Lichtdurchlassbereichen zwischen benachbarten Lichtdurchlassbereichen eine Reflektorstruktur aufweist.A particularly advantageous embodiment of the invention provides that the inner layer has a reflector structure in the area adjacent to the light passage area or in the case of a plurality of light passage areas between adjacent light passage areas.
Gelangt bei einer solchen Ausgestaltung der erfindungsgemäßen Leuchte außerdem oder alternativ von außen durch die äußere Lichtscheibe Licht nach innen, dann wird es an der Reflektorstruktur reflektiert und wieder nach außen gelenkt, wodurch die Sichtbarkeit der erfindungsgemäßen Leuchte verbessert wird.If, in such an embodiment, the luminaire according to the invention also or alternatively from the outside through the outer lens light to the inside, then it is reflected at the reflector structure and directed outwards again, whereby the visibility of the lamp according to the invention is improved.
Die Reflektorstruktur kann beispielsweise als Rückstrahlergeometrie ausgebildet sein. Eine solche Rückstrahlergeometrie kann beispielsweise pyramidenförmige Elemente umfassen.The reflector structure may be formed, for example, as Rückstrahlergeometrie. Such a reflector geometry may include, for example, pyramidal elements.
Vorzugsweise weist die innere Lichtscheibe mehrere mit Abstand nebeneinander liegende Lichtdurchlassbereiche auf.Preferably, the inner lens has a plurality of spaced apart light passage areas.
Die innere Lichtscheibe hat vorteilhaft mehr als einen als lichtdurchlässigen Bereich mit Linsenstruktur ausgebildeten streifenförmigen Lichtdurchlassbereich.The inner lens advantageously has more than one light-transmissive region with lens structure formed strip-shaped light transmission region.
Vorteilhaft ist zwischen den Linsenstrukturen an der dem Leuchtmittel zugewandten Seite wenigstens eine Reflektorstruktur vorhanden. Die Reflektorstruktur erhöht nochmals die seitliche Fläche der geometrischen Sichtbarkeit und deren Lichtwerte.Advantageously, at least one reflector structure is present between the lens structures on the side facing the light source. The reflector structure again increases the lateral area of the geometric visibility and its light values.
Im Bereich neben dem Lichtdurchlassbereich bzw. bei mehreren Lichtdurchlassbereichen vorzugsweise neben und zwischen den Lichtdurchlassbereichen, bzw. zwischen den Linsenstrukturen ist die innere Lichtscheibe für das vom Leuchtmittel kommende Licht vorzugsweise lichtundurchlässig. Die Lichtstrahlen, die in diesen Bereichen auftreffen, werden in der Leuchte so lange reflektiert, bis das Licht durch einen der streifenförmigen Lichtdurchlassbereiche durch die innere Lichtscheibe gelangen kann. Dadurch weist das durch den bzw. die streifenförmigen Lichtdurchlassbereiche austretende Licht eine höhere Intensität auf, als wenn die zwischen den einen oder mehrere streifenförmige Lichtdurchlassbereiche bildenden Linsenstrukturen liegenden Bereiche der inneren Lichtscheibe für das vom Leuchtmittel kommende Licht durchlässig wären. Dadurch wird ein wesentlich markanteres und ansprechenderes Lichtbild der Leuchte erzeugt und darüber hinaus der Lichtleitereindruck nochmals verstärkt.In the area next to the light passage area or in the case of several light passage areas, preferably adjacent to and between the light passage areas, or between the lens structures, the inner lens is preferably opaque to light from the light source. The light rays that strike in these areas are reflected in the light until the light can pass through one of the strip-shaped light transmission areas through the inner lens. As a result, the light emerging through the strip-shaped light transmission regions has a higher intensity than if the regions of the inner glass pane lying between the one or more strip-shaped light transmission regions were transparent to the light coming from the lighting device. As a result, a much more striking and appealing light image of the lamp is generated and beyond the fiber optic impression reinforced.
Zwischen der inneren Lichtscheibe und dem Leuchtmittel kann eine beispielsweise als Fresnellinse ausgebildete Optikscheibe angeordnet sein.Between the inner lens and the light source can be arranged, for example, designed as a Fresnel lens optical disc.
Zumindest ein neben einem Lichtdurchlassbereich und/oder zwischen benachbarten Lichtdurchlassbereichen liegender Bereich der inneren Lichtscheibe kann auf der dem Leuchtmittel abgewandten Seite der inneren Lichtscheibe mit einer Rauchglasschicht versehen sein.
Die Rauchglasschicht kann durch eine äußere Schicht der die inneren Lichtscheibe gebildet sein. Ebenso ist denkbar, dass die Rauchglasschicht durch Bedrucken der inneren Lichtscheibe, oder durch Einlegen einer Folie hergestellt ist, oder durch ein auf der dem Leuchtmittel abgewandten Seite der inneren Lichtscheibe angeordnetes Teil gebildet wird, oder durch mehrere solche Teile hergestellt ist.At least one area of the inner lying adjacent to a light transmission area and / or between adjacent light transmission areas Lens may be provided on the side facing away from the light source side of the inner lens with a smoke glass layer.
The smoked glass layer may be formed by an outer layer of the inner lens. It is also conceivable that the smoke glass layer is produced by printing on the inner lens, or by inserting a film, or by a part arranged on the side facing away from the light source side of the inner lens is formed, or is made by a plurality of such parts.
Die Leuchte kann Teil einer Heckleuchte eines Kraftfahrzeuges sein. Die Leuchten können aber auch in Fahrtrichtungsanzeigern, in Stoßstangen, in Karosserieöffnungen, in Außenrückblickspiegeln und dergleichen eingebaut sein. Bei diesen Leuchten wird der Effekt eines Lichtleiters durch die erfindungsgemäße Ausbildung erreicht bzw. verstärkt.The lamp may be part of a tail lamp of a motor vehicle. The lights can also be installed in direction indicators, in bumpers, in body openings, in exterior rearview mirrors and the like. In these lights, the effect of a light guide is achieved or enhanced by the inventive design.
Das Gehäuse bzw. der Innenraum einer erfindungsgemäßen Leuchte kann dabei in mehrere Kammern mit jeweils eigenen Leuchtmitteln, Reflektoren sowie gegebenenfalls Lichtscheiben unterteilt sein, von denen jede Kammer eine andere der einleitend beschriebenen Funktionen erfüllen kann.The housing or the interior of a luminaire according to the invention can be subdivided into a plurality of chambers, each with its own light sources, reflectors and optionally light disks, each of which chamber can fulfill another of the functions described in the introduction.
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.

Im Bereich des Reflektors 3 der Leuchte 1 ist wenigstens eine Öffnung 10 für ein Leuchtmittel 4, beispielsweise eine Glühlampe, vorgesehen. Das Leuchtmittel 4 ragt auch durch eine Öffnung 10' in der Karosserie 11. Eine solche Montage ist von Vorteil, da bei Versagen des Leuchtmittels 4 eine leichte Austauschbarkeit möglich ist. Das Leuchtmittel 4 wird vorteilhaft durch eine einfache Verschraubung einer Fassung 5 des Leuchtmiftels 4 oder durch eine Klemmvorrichtung in seiner Lage gehalten und befestigt. Aus der Fassung 5 herausragende Anschlusskabel 6 werden mit Versorgungsleitungen verbunden.In the area of the
Zwischen dem Leuchtmittel 4 und der äußeren Lichtscheibe 16 befinden sich im Gehäuse 2 eine der äußeren Lichtscheibe 16 benachbart liegende innere Lichtscheibe 20 und eine dem Leuchtmittel 4 benachbarte Optikscheibe 15. Die Optikscheibe 15 kann beispielsweise eine Fresnellinse sein. Durch sie wird das in alle Richtungen abgestrahlte Licht 8 des Leuchtmittels 4 annähernd parallel auf die innen liegende Lichtscheibe 20 umgelenkt. Dieses im Wesentlichen parallele Licht 8 trifft auf den rückseitigen Bereich der inneren Lichtscheibe 20.Between the illuminant 4 and the
Auch die innere Lichtscheibe 20 ist vorteilhaft in einem zwei- oder mehrschichtigen Spritzgießverfahren entsprechend der äußeren Lichtscheibe 16 hergestellt. Im dargestellten Ausführungsbeispiel besteht die innere Lichtscheibe 20 aus einer inneren Schicht 22 und einer äußeren Schicht 21. Die innere Schicht weist auf ihrer dem Leuchtmittel 4 zugewandten Seite Rückstrahlergeometrien 24 auf. Zwischen den Rückstrahlergeometrien 24 sind in Leuchtenquerrichtung sich erstreckende Lichtdurchlassbereiche 14 (
Die der Optikscheibe 15 zugewandte Unterseite 25 der Linsenstrukturen 23 ist eben ausgebildet. Vorteilhaft liegen die Unterseiten 25 parallel zur äußeren Lichtscheibe 16. Die ebenen Unterseiten 25 trennen die Rückstrahlergeometrien 24 voneinander, die sich ebenfalls an der der Optikscheibe 15 zugewandten Unterseite der inneren Schicht 22 der inneren Lichtscheibe 20 befinden. Die Rückstrahlergeometrien 24 liegen, in Richtung der Strahlen 8 gesehen, seitlich neben den Linsenstrukturen 23.The
Das vom Leuchtmittel 4 abgestrahlte Licht 8 wird durch die Optikscheibe 15 parallel gerichtet und gelangt an den ebenen Lichtdurchtrittsflächen 25 durch die Linsenstrukturen 23 zur äußeren Lichtscheibe 16, durch welche die Lichtstrahlen 8 in Abstrahlrichtung 7 nach außen treten. Da die Außenseite 32 der Linsenstrukturen 23 konvex gekrümmt ist, werden die Strahlen 8 beim Durchtritt aufgefächert bzw. gebündelt, bevor es durch die äußere Lichtscheibe 16 nach außen tritt.The light emitted by the illuminant 4 8 is directed parallel through the
