Abstract
Die Erfindung betrifft eine Leuchtenanordnung für ein Kraftfahrzeug mit einem Gehäuse (6), in dem mindestens eine Lichtquelle (9), mindestens ein dieser Lichtquelle (9) zugeordnetes erstes Lichtleitelement (8), mindestens eine erste Reflektoranordnung (10) und eine Blendenanordnung (14) vorgesehen sind, derart, dass Licht von der Lichtquelle (9) in das Lichtleitelement (8) einkoppelbar ist und mittels der Reflektoranordnung (10) als Hauptlicht über eine Hauptlichtaustrittsfläche (12) aus dem Gehäuse (6) auskoppelbar ist, wobei hinter dem Lichtleitelement (8), an einer von der Hauptlichtaustrittsfläche (12) abgewandten Seite, ein zweites Lichtleitelement (22) mit einer zweiten Reflektoranordnung (26, 28) vorgesehen ist, um Restlicht des ersten Lichtleitelementes (8) aufzufangen und zu nutzen.The invention relates to a luminaire arrangement for a motor vehicle having a housing (6) in which at least one light source (9), at least one first light guide element (8) associated with this light source (9), at least one first reflector arrangement (10) and one shutter arrangement (14 ) are provided, such that light from the light source (9) in the light guide (8) can be coupled and by means of the reflector assembly (10) as the main light via a main light exit surface (12) from the housing (6) can be decoupled, wherein behind the light guide (8), on a side remote from the main light exit surface (12) side, a second light-guiding element (22) with a second reflector arrangement (26, 28) is provided to absorb and use residual light of the first light-guiding element (8).
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 lighting arrangement for a motor vehicle having a housing in which at least one light source, at least one first light guide associated with this light source, at least a first reflector arrangement and a diaphragm arrangement are provided, such that light from the light source can be coupled into the light guide and means the reflector assembly as the main light via a main light exit surface from the housing can be coupled out.
Derartige Leuchtenanordnungen sind aus dem Stand der Technik hinlänglich bekannt und werden insbesondere als Fahrzeugheckleuchte eingesetzt. Ein Beispiel für eine derartige Leuchtenanordnung ist der
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 above-mentioned disadvantages 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 guide, on a side facing away from the main light exit surface side, a second light guide is provided with a second reflector assembly to collect residual light of the first light guide and use. By means of such an embodiment according to the invention, it is possible to achieve a depth effect in the luminaire arrangement in a relatively simple and cost-effective manner, wherein the existing residual light can be used to achieve the depth effect.
In einer vorteilhaften Ausführungsform 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. In an advantageous embodiment, 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 surface light-guiding element with a second reflector arrangement. In this case, the surface light guide element can have, as a second reflector arrangement, two glass surfaces extending parallel to one another such that a 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. In particular, for the representation of a depth effect, it is advantageous if the first light-guiding element is mounted selectively only via means in the housing. It is particularly advantageous if the means are provided for selective storage by the diaphragm assembly. 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.
Die Erfindung wird anhand einer Zeichnung näher dargestellt, hierbei zeigt: The invention is illustrated in more detail with reference to a drawing, in which:
