Abstract
Description
Die Erfindung betrifft eine Reflektoranordnung für eine Beleuchtungsvorrichtung mit mehreren Reflektorelementen, wobei erste Reflektorelemente derart angeordnet sind, dass diese direkt von einer Lichtquelle in Richtung der ersten Reflektorelemente ausgesendete Lichtstrahlung in eine vorgegebene Richtung reflektieren.The invention relates to a reflector arrangement for a lighting device with a plurality of reflector elements, wherein first reflector elements are arranged such that they reflect directly emitted by a light source in the direction of the first reflector elements light radiation in a predetermined direction.
Die Erfindung betrifft weiterhin eine Beleuchtungsvorrichtung, umfassend zumindest eine solche Reflektoranordnung.The invention further relates to a lighting device comprising at least one such reflector arrangement.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, eine gegenüber dem Stand der Technik verbesserte Reflektoranordnung für eine Beleuchtungsvorrichtung und eine Beleuchtungsvorrichtung mit einer solchen Reflektoranordnung anzugeben.The invention has for its object to provide a comparison with the prior art improved reflector assembly for a lighting device and a lighting device with such a reflector assembly.
Hinsichtlich der Reflektoranordnung wird die Aufgabe erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale und hinsichtlich der Beleuchtungsvorrichtung durch die im Anspruch 5 angegebenen Merkmale gelöst.With regard to the reflector arrangement, the object is achieved by the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Die Reflektoranordnung für eine Beleuchtungsvorrichtung umfasst zumindest eine Lichtquelle und mehrere Reflektorelemente, wobei erste Reflektorelemente derart angeordnet sind, dass diese direkt von der Lichtquelle in Richtung der ersten Reflektorelemente ausgesendete Lichtstrahlung in eine vorgegebene Richtung reflektieren.The reflector arrangement for a lighting device comprises at least one light source and a plurality of reflector elements, wherein first reflector elements are arranged such that they reflect light emitted directly from the light source in the direction of the first reflector elements in a predetermined direction.
Erfindungsgemäß ist zumindest eine Reflexionsfläche vorgesehen, welche von der Lichtquelle in Richtung der Reflexionsfläche ausgesendete Lichtstrahlung in Richtung von zweiten Reflektorelementen reflektiert, wobei die zweiten Reflektorelemente zumindest abschnittsweise unmittelbar an die ersten Reflektorelemente angrenzen und seitlich außerhalb einer Haupt-Abstrahlcharakteristik der Lichtquelle angeordnet sind.According to the invention, at least one reflection surface is provided, which reflects light radiation emitted by the light source in the direction of the reflection surface in the direction of second reflector elements, wherein the second reflector elements at least partially directly adjoin the first reflector elements and are arranged laterally outside a main emission characteristic of the light source.
Die erfindungsgemäße Reflektoranordnung ermöglicht eine hohe lichttechnische Effizienz, da von der Lichtquelle emittiertes Licht, das nicht direkt auf die ersten Reflektorelemente fällt, von der zumindest einen Reflexionsfläche derart umgelenkt wird, dass es auf die zweiten Reflektorelemente fällt und somit zur Erzeugung einer Lichtverteilung nutzbar ist. Aus der erfindungsgemäßen Anordnung der zweiten Reflektorelemente folgt eine verbesserte Homogenität der Lichtverteilung und der damit realisierten Ausleuchtung. Insbesondere können bogenförmige Erscheinungsbilder der Lichtverteilung vermieden werden. Insbesondere steht die von der zumindest einen Reflexionsfläche zu den zweiten Reflektorflächen abgelenkte Lichtstrahlung zur Erzeugung einer Signallichtfunktion und/oder einer Fahrlichtverteilung für ein Fahrzeug zusätzlich zur Verfügung.The reflector arrangement according to the invention enables a high photometric efficiency, since light emitted by the light source, which does not fall directly on the first reflector elements, is deflected by the at least one reflection surface in such a way that it falls onto the second reflector elements and thus can be used to produce a light distribution. From the arrangement of the second reflector elements according to the invention, an improved homogeneity of the light distribution and the illumination realized thereby follows. In particular, arcuate appearances of the light distribution can be avoided. In particular, the light radiation deflected from the at least one reflection surface to the second reflector surfaces is additionally available for generating a signal light function and / or a driving light distribution for a vehicle.
