Description
Die Erfindung betrifft eine Leuchtenanordnung für ein Kraftfahrzeug mit einem Gehäuse, in dem mindestens eine Lichtquelle, mindestens ein dieser Lichtquelle zugeordnetes erstes Lichtleitelement, mindestens eine erste Reflektoranordnung und eine Blendenanordnung vorgesehen sind, derart, dass Licht von der Lichtquelle in den Lichtleiter einkoppelbar ist und mittels der Reflektoranordnung als Hauptlicht über eine Hauptlichtaustrittsfläche aus dem Gehäuse auskoppelbar ist.The invention relates to a lamp arrangement for a motor vehicle with a housing in which at least one light source, at least one first light-guiding element assigned to this light source, at least one first reflector arrangement and a screen arrangement are provided, such that light from the light source can be coupled into the light guide and by means of the reflector arrangement can be coupled out of the housing as the main light via a main light exit surface.

Aufgabe der Erfindung ist es, die oben genannten Nachteile auf möglichst einfache und kostengünstige Art und Weise zu vermeiden.The object of the invention is to avoid the disadvantages mentioned above in the simplest and most cost-effective manner possible.
Diese Aufgabe wird dadurch gelöst, dass hinter dem Lichtleitelement, an einer von der Hauptlichtaustrittsfläche abgewandten Seite, ein zweites Lichtleitelement mit einer zweiten Reflektoranordnung vorgesehen ist, um Restlicht des ersten Lichtleitelementes aufzufangen und zu nutzen. Durch eine derartige erfindungsgemäße Ausführungsform ist es möglich, auf relativ einfache und kostengünstige Weise eine Tiefenwirkung in der Leuchtenanordnung zu erzielen, wobei zur Erzielung der Tiefenwirkung das vorhandene Restlicht genutzt werden kann.This object is achieved in that behind the light-guiding element, on a side facing away from the main light exit surface, a second light-guiding element is provided with a second reflector arrangement in order to capture and use residual light from the first light-guiding element. Such an embodiment according to the invention makes it possible to achieve a depth effect in the lighting arrangement in a relatively simple and cost-effective manner, it being possible to use the existing residual light to achieve the depth effect.
Erfindungsgemäß ist das erste Lichtleitelement als zylindrisches Lichtleitelement mit einer ersten Reflektoranordnung ausgeführt. Das zweite Lichtleitelement ist vorteilhafterweise als Flächenlichtleitelement mit einer zweiten Reflektoranordnung ausgeführt. Hierbei kann das Flächenlichtleitelement als zweite Reflektoranordnung zwei parallel zueinander verlaufende Glasflächen aufweisen, derart, dass eine totale interne Reflektion stattfindet. Auch kann das zweite Lichtleitelement Streustrukturen, wie zum Beispiel eine Narbung, Mattierung, etc. aufweisen.According to the invention, the first light-guiding element is designed as a cylindrical light-guiding element with a first reflector arrangement. The second light-guiding element is advantageously designed as a planar light-guiding element with a second reflector arrangement. In this case, the planar light-guiding element, as the second reflector arrangement, can have two glass surfaces running parallel to one another, in such a way that total internal reflection takes place. The second light-guiding element can also have scattering structures, such as graining, matting, etc.
Insbesondere zur Darstellung einer Tiefenwirkung ist es vorteilhaft, wenn das erste Lichtleitelement lediglich über Mittel punktuell im Gehäuse gelagert ist. Hierbei ist es besonders vorteilhaft, wenn die Mittel zur punktuellen Lagerung durch die Blendenanordnung vorgesehen sind. Für eine optimale Tiefenwirkung ist es darüber hinaus vorteilhaft, wenn das Gehäuse zumindest teilweise transparent ausgeführt ist.It is advantageous, in particular to create a depth effect, if the first light-guiding element is mounted in the housing only at certain points via the center. It is particularly advantageous here if the means for selective storage are provided by the panel arrangement. For an optimal depth effect, it is also advantageous if the housing is at least partially transparent.
Auch ist es vorteilhaft, wenn das Gehäuse zumindest teilweise transparent ausgeführt ist.It is also advantageous if the housing is at least partially transparent.
