Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass die Rückseite des flächigen Lichtleiters mindestens einen streuenden Bereich mit hoher Streuwirkung aufweist zur Bildung eines ersten Flächenbereiches der Leuchteinheit, wobei sich im ersten Flächenbereich an die Vorderseite des flächigen Lichtleiters in Lichtabstrahlrichtung der Leuchteinheit ein Lichtscheibenprofil mit einer sich in Lichtabstrahlrichtung von dem flächigen Lichtleiter erhabenen Profilierung anschließt, und dass sich an den ersten Flächenbereich ein zweiter Flächenbereich mit einer geringen oder keinen Streuwirkung anschließt.to solution This object is the invention in conjunction with the preamble of the patent claim 1, characterized in that the back of the plane Light guide at least one scattering area with high scattering effect has to form a first surface area of the lighting unit, being in the first area on the front of the plane Light guide in Lichtabstrahlrichtung the light unit a lens profile with a light emission direction from the planar light guide sublime profiling follows, and that adjoins the first surface area second surface area with a low or no scattering effect connects.
Der besondere Vorteil der Erfindung besteht darin, dass durch Kombination eines flächigen Lichtleiters mit mindestens einem Lichtscheibenprofil zum einen das Erscheinungsbild einer leuchtenden Fläche quasi als „Lichtvorhang" und zum anderen ein Erscheinungsbild mit Tiefeneindruck erzeugt wird. Erfindungsgemäß ist mindestens ein Lichtscheibenprofil einem streuenden Bereich des flächigen Lichtleiters zugeordnet, so dass ein erster Flächenbereich geschaffen wird, in dem die Leuchteinheit das Erscheinungsbild mit Tiefenwirkung aufweist. Zum anderen ist ein sich an den ersten Flächenbereich anschließender zweiter Flächenbereich des flächigen Lichtleiters vorgesehen, in dem durch den flächigen Lichtleiter nur eine geringe oder keine Streuwirkung erzielt wird. Wird in dem zweiten Flächenbereich (Zwischenbereich) des Lichtleiters keine Streuwirkung erzielt, werden nur die Lichtscheibenprofile ausgeleuchtet. Weist der zweite Flächenbereich (Zwischenbereich) eine geringe Streuwirkung auf, wird eine flächige Grundausleuchtung geschaffen, wobei der erste Flächenbereich einen relativ hohen Ausleuchtungsgrad mit Tiefeneindruck erfährt.Of the particular advantage of the invention is that by combination a flat Light guide with at least one lens profile on the one hand the appearance of a luminous surface quasi as a "light curtain" and on the other an appearance with depth impression is generated. According to the invention is at least a lens profile a scattering region of the planar light guide assigned, so that a first surface area is created, in which the lighting unit the appearance with depth effect having. On the other hand, one is on the first surface area followed by second surface area of the planar light guide provided in which by the planar light guide only little or no scattering effect is achieved. Will in the second surface area (intermediate area) the light guide scored no scattering effect, only the lens profiles illuminated. Indicates the second surface area (intermediate area) a low scattering effect, a planar basic illumination is created, the first surface area Experience a relatively high degree of illumination with depth impression.
Nach einer bevorzugten Ausführungsform der Erfindung ist das Lichtscheibenprofil domförmig ausgebildet mit einer Länge, die um ein vielfaches größer ist als die Dicke des flächigen Lichtleiters. Die Länge des Lichtscheibenprofils kann beispielsweise zehnmal so groß sein wie die Dicke des flächigen Lichtleiters. Auf diese Weise wird ein Erscheinungsbild mit einem verbesserten Tiefeneindruck im so gebildeten ersten Flächenbereich erzeugt.To a preferred embodiment of Invention, the lens profile is dome-shaped with a Length, which is many times bigger as the thickness of the plane Light guide. The length of the lens profile can be for example ten times as large as the thickness of the planar light guide. In this way, an appearance with an improved Depth impression produced in the first area thus formed.
Nach einer Weiterbildung der Erfindung kann eine Vorderfläche des Lichtscheibenprofils konvex- oder konkav- oder stufenförmig ausgebildet sein. Hierdurch kann ein unterschiedliches Ausleuchtungsdesign bereitgestellt werden.To a development of the invention, a front surface of the Lens profile convex or concave or stepped formed be. This can provide a different illumination design become.
Nach einer Weiterbildung der Erfindung können eine Vorderfläche und/oder eine Seitenfläche des Lichtscheibenprofils vollständig oder teilweise mit Optikelementen versehen sein, so dass eine lichttechnische Optimierung gewährleistet ist.To a development of the invention, a front surface and / or a side surface of the Lens profile complete or be partially provided with optical elements, so that a lighting technology Optimization guaranteed is.
Nach einer Weiterbildung der Erfindung deckt der flächige Lichtleiter eine vordere Öffnung eines in Lichtabstrahlrichtung hinter dem flächigen Lichtleiter angeordneten Reflektor vollständig ab, so dass der flächige Lichtleiter bzw. die Lichtscheibenprofile zur Durchleuchtung des durch die dem Reflektor zugeordneten Lichtquelle emittierten Lichtes dient. Der Reflektor und die demselben zugeordnete Lichtquelle dienen zur Erzeugung einer ersten Lichtfunktion. Der flächige Lichtleiter und die demselben zugeordnete Lichtquelle dienen zur Erzeugung einer zweiten Lichtfunktion. Die Lichtquellen der unterschiedlichen Lichtfunktionen sind im Wesentlichen rechtwinklig zueinander ausgerichtet. Vorteilhaft kann hierdurch eine Platz sparende Anordnung von unterschiedlichen Lichtfunktionen erzeugt werden.According to a development of the invention, the planar light guide covers a front opening ei Nes in the light emission direction behind the planar light guide arranged reflector completely, so that the planar light guide or the light disk profiles for the illumination of the light emitted by the reflector associated with the light source used. The reflector and the light source associated therewith serve to generate a first light function. The planar light guide and the light source associated therewith serve to generate a second light function. The light sources of the different light functions are aligned substantially at right angles to each other. Advantageously, thereby a space-saving arrangement of different light functions can be generated.
Nach einer Weiterbildung der Erfindung kann eine zusätzliche Lichtfunktion durch eine Lichtquelle und demselben zugeordnete Optikmittel gebildet sein, die jeweils einem einzigen Lichtscheibenprofil nachgelagert sind. Hierbei kann das Lichtscheibenprofil eine lichttechnische Verstärkung der zusätzlichen Lichtfunktion bewirken. Diese Verstärkung kann insbesondere dadurch begünstigt werden, dass zusätzlich die dem flächigen Lichtleiter zugeordnete Lichtquelle eingeschaltet ist, so dass mittels des rückseitig des Lichtscheibenprofil angeordneten streuenden Bereichs eine erhöhte Leuchtstärke erzeugt wird. Beispielsweise kann hierdurch zusätzlich zu der durch den flächigen Lichtleiter bewirkten Schlusslichtfunktion eine Bremslichtfunktion erzeugt werden.To a development of the invention can be an additional light function a light source and the same associated optical means be formed each of which is located downstream of a single lens profile. Here, the lens profile can be a lighting reinforcement of the additional Cause light function. This reinforcement can be characterized in particular favored be that extra the flat Light guide associated with the light source is turned on, so that means the back the light disk profile arranged scattering area generates an increased luminous intensity becomes. For example, in addition to that through the planar light guide caused tail light function to be generated a brake light function.
