Description
Die Erfindung betrifft eine Leuchte, insbesondere für Kraftfahrzeuge, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The The invention relates to a lamp, in particular for motor vehicles, with the features of the preamble of claim 1.
Leuchten
mit Lichtleitstäben
sind hinreichend bekannt. So ist z. B. aus der
Die
Es hat sich gezeigt, dass insbesondere bei längeren Lichtleitstäben, auch bei einem gekrümmten Sockel, die Lichtverteilung entlang des Lichtleitstabes nicht gleichmäßig ist und der Lichtleitstab insbesondere im Bereich des Lichteintritts hell ist, also eine hohe Leuchtdichte aufweist, die allmählich zu der der Lichteintrittsfläche gegenüberliegenden Seite hin abnimmt.It has been shown that, especially with longer Lichtleitstäben, too in a curved Base, the light distribution along the light guide rod is not uniform and the light-conducting rod, in particular in the region of the light entrance is bright, so has a high luminance, which gradually to the the light entry surface opposite Side decreases.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Leuchte bereitzustellen, die eine gleichmäßigere Leuchtdichte besitzt.Of the The invention is therefore based on the object to provide a luminaire, the more uniform luminance has.
Diese Aufgabe wird bei einer Leuchte gelöst, die die Merkmale des Anspruchs 1 aufweist.These The object is achieved in a lamp, the features of the claim 1 has.
Die erfindungsgemäß ausgestaltete Leuchte weist also in einem Bereich, im Wesentlichen vor der Lichtaustrittsfläche, einen Lichtumlenkbereich auf, in welchem die auf diesen auftreffenden Lichtstrahlen in einen bezüglich der normalen Umlenkung ohne Lichtumlenkbereich zur Lichteintrittsfläche näher liegenden Abschnitt des Lichtleitstabes abgelenkt werden. Dieser Lichtumlenkbereich dient also dazu, die Lichtstrahlen, die vor der Lichtaustrittsfläche auf die Außenseite des Lichtleitstabes auftreffen derart abzulenken, dass diese in einen weiter vorne liegenden Abschnitt des Lichtleitstabes gelangen. Auf diese Weise wird der Abschnitt des Lichtleitstabes, der der Lichteintrittsfläche näher liegt, mit einer größeren Strahlendichte angestrahlt. Die Eintrittsstrahlen können nunmehr flacher einfallen so dass der Abschnitt des Lichtleitstabes, der der Lichteintrittsfläche entfernt liegt, mit einer höheren Strahlendichte angestrahlt wird. Auf diese Weise wird das austretende Licht wesentlich gleichmäßiger über die Länge des Lichtleitstabes verteilt.The designed according to the invention Thus, in one area, essentially in front of the light exit area, the luminaire has a Lichtumlenkbereich on, in which the incident on this Light rays in a respect the normal deflection without Lichtumlenkbereich closer to the light entry surface Be distracted portion of the light guide rod. This light deflection area thus serves to light rays, in front of the light exit surface the outside of the Lichtleitstabes deflect such a way that these in get a further forward section of the light guide rod. In this way, the portion of the light-conducting rod, which is closer to the light entry surface, with a larger beam density illuminated. The entrance rays can now be flatter so that the portion of the light-conducting rod that removes the light entry surface lies with a higher one Radiation density is illuminated. In this way, the exiting light much more uniform over the Length of the light guide rod distributed.
Erfindungsgemäß ist die Fläche derart geneigt, dass sich der Querschnitt des Lichtleitstabes ausgehend von der Lichteintrittsfläche verjüngt. Auf diese Weise wird ein Abschnitt des eintretenden Lichtkegels ausgeblendet und in einen oder mehrere andere Bereiche des Lichtleitstabes reflektiert.According to the invention area inclined so that the cross section of the light-conducting rod starting from the light entry surface rejuvenated. In this way, a section of the entering cone of light hidden and in one or more other areas of the light guide rod reflected.
Dabei wird der Lichtumlenkbereich von einer oder mehreren gekrümmten Flächen gebildet. Diese Flächen können stetig gekrümmt sein, der Umlenkbereich kann jedoch auch eine Freiformfläche sein. Hierdurch wird die Möglichkeit geschaffen, dass Lichtstrahlen exakt in diejenigen Bereiche reflektiert werden, in denen die Strahlendichte zu niedrig ist. Die Fläche kann konvex und/oder konkav gekrümmt sein. Die konvex und konkav gekrümmten Bereiche können beliebig hintereinander liegen. Außerdem können sich gekrümmte und ebene Bereiche abwechseln. Die Krümmung liegt in Längsrichtung des Lichtleitstabes. Außerdem kann die gekrümmte Fläche zusätzlich geneigt sein.there the light deflection region is formed by one or more curved surfaces. These surfaces can steadily curved However, the deflection can also be a free-form surface. hereby becomes the possibility created that light rays are reflected exactly in those areas, where the radiance is too low. The area can be curved convex and / or concave. The convex and concave curved Areas can lie arbitrarily behind each other. In addition, can be curved and alternate flat areas. The curvature lies in the longitudinal direction of the light guide rod. Furthermore can the curved area additionally be inclined.
Erfindungsgemäß wird der Lichtumlenkbereich alternativ von mehreren ebenen Flächen gebildet. Ebene Flächen haben den wesentlichen Vorteil, dass sie relativ einfach herstellbar sind und die Reflexion des dort auftretenden Lichts relativ einfach berechnet werden kann.According to the invention Lichtumlenkbereich alternatively formed of several flat surfaces. Plane surfaces have the significant advantage that they are relatively easy to produce and the reflection of the light occurring there are relatively simple can be calculated.
Erfindungsgemäß ist der Lichtumlenkbereich derart ausgebildet, dass das auf den Lichtumlenkbereich auftreffende Licht reflektiert wird. Das Licht kann also in einem anderen Bereich des Lichtleitstabes genutzt werden.According to the invention Lichtumlenkbereich formed such that on the Lichtumlenkbereich incident light is reflected. So the light can be in one be used in another area of the light guide rod.
Eine Weiterbildung sieht vor, dass der Lichtumlenkbereich in mehrere Unterbereiche unterteilt ist. Diese Unterbereiche können so gewählt werden, dass das dort auftreffende Licht gezielt in die Bereiche des Lichtleitstabes reflektiert werden, die eine geringe Strahlendichte aufweisen oder wo die Leuchtdichte des Lichtleitstabes erhöht werden soll.A Further development provides that the light deflection area in several Subareas is divided. These subsections can do so chosen be that the light striking there targeted into the areas the light guide rod are reflected, which has a low radiation density or where the luminance of the Lichtleitstabes be increased should.
Erfindungsgemäß steht die Fläche unter einem Winkel zur Achse des Lichtleitstabes. Auf diese Weise wird das auf den Umlenkbereich auftreffende Licht stärker in Richtung der Achse reflektiert, d. h. das reflektierte Licht kann gezielt in bestimmte Bereiche des Lichtleitstabes gelenkt werden.According to the invention, the surface is at an angle to the axis of the light-conducting rod. In this way, the incident on the deflection area Reflected light stronger in the direction of the axis, ie the reflected light can be targeted directed into certain areas of the Lichtleitstabes.
Eine andere Ausführungsform sieht vor, dass die Fläche unter einem Winkel zur Außenoberfläche des Lichtleitstabes steht. Auch bei diesem Ausführungsbeispiel kann durch die Winkellage der Fläche bzw. des Lichtumlenkbereichs das von diesem reflektierte Licht gezielt in dunklere Bereiche oder aufzuhellende Bereiche des Lichtleitstabes reflektiert werden.A other embodiment Provides that area at an angle to the outer surface of the Lichtleitstabes stands. Also in this embodiment can by the Angular position of the surface or the Lichtumlenkbereichs targeted by this light reflected in darker areas or brightening areas of the light guide rod be reflected.
Eine Weiterbildung sieht vor, dass die Außenseite des Lichtleitstabes nach dem Lichtumlenkbereich mit einer den Querschnitt des Lichtleitstabes vergrößernden Stufe versehen ist. Diese Ausgestaltung der Außenseite des Lichtleitstabes bewirkt eine Teilabschattung eines sich an den Lichtumlenkbereich anschließenden Abschnitts der Lichtaustrittsfläche. Mit dieser Stufe kann gezielt auf zu helle Abschnitte, in welcher die Strahlendichte zu hoch ist, eingewirkt werden, indem ein Teil dieser Strahlen über die Stufe abgeschattet und über den Lichtumlenkbereich in einen oder mehrere andere Abschnitte der Lichtaustrittsfläche reflektiert werden. Mit dem Lichtumlenkbereich werden also Strahlen gezielt in zu dunkle Abschnitte der Lichtaustrittsfläche reflektiert und mit der Stufe werden gezielt zu helle Abschnitte der Lichtaustrittfläche teilabgeschattet.A Continuation provides that the outside of the light guide rod after the Lichtumlenkbereich with a cross-section of the Lichtleitstabes magnifying Stage is provided. This embodiment of the outside of the light guide rod causes a Teilabschattung one to the Lichtumlenkbereich subsequent Section of the light exit surface. With this stage you can target too bright sections in which the radiance is too high, being acted upon by a part these rays over the level is shaded and over the light deflection area in one or more other sections of the Light-emitting surface be reflected. With the Lichtumlenkbereich be so rays deliberately reflected in too dark sections of the light exit surface and with the step are selectively shadowed too bright sections of the light exit surface.
Bevorzugt entspricht die Höhe der Stufe der Querschnittsreduzierung des Lichtleitstabes im Lichtumlenkbereich. Somit weist der Lichtleitstab im Anschluss an die Stufe wieder seinen Ausgangsquerschnitt auf.Prefers corresponds to the height the stage of the cross-section reduction of the light-conducting rod in the Lichtumlenkbereich. Thus, the Lichtleitstab following the stage again its Output cross section on.
Vorteilhaft ist bzw. sind die Flächen des Lichtumlenkbereichs und/oder die Außenfläche der Stufe verspiegelt. Hierdurch wird eine optimale Reflexion des auf diese Bereiche auftreffenden Lichts erzielt.Advantageous is or are the surfaces the Lichtumlenkbereichs and / or the outer surface of the step mirrored. As a result, an optimal reflection of the incident on these areas Achieved light.
Gemäß einem Ausführungsbeispiel ist der Lichtleitstab gebogen und sind der Lichtumlenkbereich und/oder die Stufe an der Bogeninnenseite vorgesehen. Insbesondere bei gebogenen Lichtleitstäben, bei denen eine gleichmäßige Lichtverteilung relativ schwierig ist, kann sowohl über den Lichtumlenkbereich als auch über die Stufe ein Teil des eingestrahlten Lichtes exakt von zu hellen Bereichen in dunklere Bereiche umgelenkt werden.According to one embodiment the light guide rod is bent and are the Lichtumlenkbereich and / or the step provided on the inside of the arch. Especially with bent optical fiber rods, where a uniform light distribution Relatively difficult can be both over the light deflection range as well over the stage part of the incident light exactly from too bright Areas are redirected to darker areas.
