Abstract
Description
Die Erfindung betrifft eine Beleuchtungsvorrichtung für Fahrzeuge mit einer Anzahl von reihenförmig angeordneten Lichtquellen und mit einem in Hauptabstrahlrichtung vor den Lichtquellen angeordneten flächigen Lichtleitelement enthaltend zwei gegenüberliegende Flachseiten und mindestens zwei gegenüberliegende Schmalseiten, wobei eine erste Schmalseite jeweils eine einer Lichtquelle zugeordnete Lichteinkoppelfläche, eine zweite Schmalseite ein mit einer linsenförmigen Oberfläche versehenen Lichtauskoppelfläche aufweist und wobei das an der ersten Schmalseite eingekoppelte Licht an den Flachseiten in Richtung der zweiten Schmalseite totalreflektierbar ist.The invention relates to a lighting device for vehicles having a number of light sources arranged in rows and having a two-sided light guide element arranged in the main emission direction, comprising two opposite flat sides and at least two opposite narrow sides, wherein a first narrow side in each case one light input surface associated with a light source, a second narrow side having a lenticular surface provided light output surface and wherein the light coupled on the first narrow side light on the flat sides in the direction of the second narrow side is totally reflectable.
Aus der
Aufgabe der vorliegenden Erfindung ist es, eine Beleuchtungsvorrichtung für Fahrzeuge enthaltend ein flächiges Lichtleitelement derart weiterzubilden, dass das in das flächige Lichtleitelement eingekoppelte Licht zur Erzeugung einer vorgegebenen Lichtverteilung effizienter „verarbeitet” wird und insbesondere eine verbesserte homogene Ausleuchtung der schmalseitigen Lichtauskoppelfläche bewirkt wird.The object of the present invention is to develop a lighting device for vehicles comprising a planar light guide such that the light coupled into the planar light guide is "processed" more efficiently to produce a given light distribution and, in particular, an improved homogeneous illumination of the narrow-side light outcoupling surface is effected.
Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass die linsenförmige Oberfläche der zweiten Schmalseite als eine aus einer Mehrzahl von streifenförmig zwischen den Flachseiten verlaufenden Linsensegmenten gebildete Auskoppellinse ausgebildet ist.To achieve this object, the invention in conjunction with the preamble of
Der besondere Vorteil der Erfindung besteht darin, dass an einer lichtauskoppelseitigen Schmalseite eines flächigen Lichtleitelementes eine Auskoppellinse mit einer Mehrzahl von Linsensegmenten gebildet wird, die optimal auf eine lichteinkoppelseitig angeordnete Lichtquelle abgestimmt ist. Die quer zu einer Längsmittelebene des flächigen Lichtleitelementes angeordneten Linsensegmente sind jeweils auf die in Hauptabstrahlrichtung hinter der Auskoppellinse angeordnete Lichtquelle abgestimmt, so dass eine Lichtverteilung zur Bildung einer vorgegebenen Signalfunktion erzeugt werden kann. Grundgedanke der Erfindung ist es, mindestens eine segmentierte Auskoppellinse an einer schmalseitigen Lichtauskoppelfläche eines flächigen Lichtleitelementes auszubilden, so dass ein schmales Lichtband beispielsweise Konturen folgend an einem Rand eines Gehäuses der Beleuchtungsvorrichtung gebildet wird.The particular advantage of the invention is that a coupling-out lens with a plurality of lens segments is formed on a light output side narrow side of a planar light guide, which is optimally tuned to a lichteinkoppelseitig arranged light source. The lens segments arranged transversely to a longitudinal center plane of the planar light-guiding element are respectively tuned to the light source arranged behind the coupling-out lens in the main emission direction, so that a light distribution can be generated to form a predetermined signal function. The basic idea of the invention is to form at least one segmented coupling-out lens on a narrow-side light outcoupling surface of a planar light-guiding element, so that a narrow light band is formed, for example, following contours on an edge of a housing of the lighting device.
Nach einer bevorzugten Ausführungsform der Erfindung weist die Auskoppellinse eine in Längsrichtung der zweiten Schmalseite konvexförmige und/oder bogenförmige Randkontur auf. Die Formgebung der Auskoppellinse ermöglicht somit eine Lichtverteilung vorzugsweise in einer Längsmittelebene des flächigen Lichtleitelementes. Dadurch, dass die Linsensegmente der Auskoppellinse quer zur Formgebung der Auskoppellinse bzw. quer zur Längsmittelebene des flächigen Lichtleitelementes verlaufen, kann zur Erzeugung einer vorgegebenen Signalfunktion die Lichtverteilung in der Längsmittelebene des flächigen Lichtleitelementes weiter gesteuert werden. Vorzugsweise erstreckt sich das flächige Lichtleitelement in einer horizontalen Ebene. Die Konturierung der Auskoppellinse bzw. der Linsensegmente in vertikaler Richtung bzw. quer zur Längsmittelebene des flächigen Lichtleitelementes kann somit gleich ausgebildet sein.According to a preferred embodiment of the invention, the coupling-out lens has a convex-shaped and / or arc-shaped edge contour in the longitudinal direction of the second narrow side. The shaping of the coupling-out lens thus permits a light distribution, preferably in a longitudinal center plane of the planar light-guiding element. Due to the fact that the lens segments of the coupling-out lens run transversely to the shaping of the coupling-out lens or transversely to the longitudinal center plane of the planar light-guiding element, the light distribution in the longitudinal center plane of the planar light-guiding element can be further controlled to produce a predetermined signal function. Preferably, the planar light guide extends in a horizontal plane. The contouring of the coupling-out lens or of the lens segments in the vertical direction or transversely to the longitudinal center plane of the planar light-guiding element can thus be of the same design.
Nach einer Weiterbildung der Erfindung sind Lichtquellen an der ersten Schmalseite des flächigen Lichtleitelementes und Auskoppellinsen an einer Schmalseite des zweiten Lichtleitelementes jeweils in einem solchen Abstand zueinander angeordnet und eine Tiefe des flächigen Lichtleitelementes derart ausgebildet, dass die von den jeweiligen Lichtquellen abgestrahlten und eingekoppelten Lichtbündel ausschließlich von den jeweiligen in Hauptabstrahlrichtung vorgelagerten Auskoppellinsen erfasst werden. Es ergibt sich hierdurch eine eindeutige räumliche Zuordnung, wobei ein Lichtquellen-Auskoppellinsen-Paar gebildet wird, die eine in Hauptabstrahlrichtung verlaufende gemeinsame Achse aufweisen. Sind die Lichtquellen bzw. die Auskoppellinsen jeweils in einem relativ geringen Abstand zueinander angeordnet, kann die Tiefe des flächigen Lichtleitelementes kleiner gewählt werden, was zu einer verringerten Bautiefe der Beleuchtungsvorrichtung führt.According to a development of the invention, light sources on the first narrow side of the planar light guide element and coupling lenses on a narrow side of the second light guide are each arranged at such a distance from each other and formed a depth of the planar light guide element such that the radiated from the respective light sources and coupled light beam exclusively from the respective outgoing in the main emission direction Auskoppellinsen be detected. This results in a clear spatial assignment, wherein a light source Auskoppellinsen pair is formed having a common axis extending in the main emission direction. If the light sources or the coupling-out lenses are each arranged at a relatively small distance from each other, the depth of the planar light-guiding element can be be selected smaller, resulting in a reduced depth of the lighting device.
Vorzugsweise sind die Auskoppellinsen unmittelbar anschließend in Längsrichtung der zweiten Schmalseite angeordnet, so dass ein durchgehendes homogenes linienförmiges Leuchtband erzeugt werden kann.Preferably, the coupling-out lenses are arranged immediately thereafter in the longitudinal direction of the second narrow side, so that a continuous homogeneous line-shaped light strip can be produced.
Nach einer bevorzugten Ausführungsform der Erfindung sind die Linsensegmente prismenförmig ausgebildet mit einer vorderen Prismenkante, die geradlinig oder bogenförmig zwischen Randkanten der zweiten Schmalseite verlaufen. Durch Vorgabe einer Teilung dieser prismenförmigen Linsensegmente kann die Lichtverteilung bzw. die Homogenität der Ausleuchtung beeinflusst werden. Für eine gute Homogenität der Ausleuchtung kann die Teilung relativ klein gewählt werden. Mit entsprechenden Fertigungsverfahren kann auch eine Mikroteilung (Mikrooptik) vorgesehen sein.According to a preferred embodiment of the invention, the lens segments are prism-shaped with a front edge of the prism, which extend straight or arcuate between marginal edges of the second narrow side. By specifying a division of these prism-shaped lens segments, the light distribution or the homogeneity of the illumination can be influenced. For a good homogeneity of the illumination, the pitch can be chosen relatively small. With appropriate manufacturing methods, a micro-division (micro-optics) may be provided.
Nach einer Weiterbildung der Erfindung ragt an der ersten Schmalseite des flächigen Lichtleitelementes ein ellipsoidförmiger Dom ab, in dem eine Lichteinkoppelfläche integriert angeordnet ist. Die Randflächen des ellipsoidförmigen Domes können zur Totalreflexion des eingekoppelten Lichtes genutzt werden, so dass eine wirkungsvollere Bündelung des Lichtes im Bereich der Auskoppellinsen bewirkt werden kann.According to a development of the invention, an ellipsoidal dome protrudes on the first narrow side of the planar light-guiding element, in which a light-coupling surface is integrated. The edge surfaces of the ellipsoidal dome can be used for total reflection of the coupled-in light, so that a more effective focusing of the light in the region of the coupling-out lenses can be effected.
Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further advantages of the invention will become apparent from the further subclaims.
