Abstract
Description
Die Erfindung betrifft einen Scheinwerfer für Fahrzeuge mit einer Mehrzahl von LED-Lichtquellen, die zur Bildung eines LED-Feldes auf einem gemeinsamen Substrat gruppiert angeordnet sind und die jeweils ein Teillichtbündel emittieren, und mit einer dem LED-Feld vorgelagerten Optikeinheit, so dass die Teillichtbündel der LED-Lichtquellen jeweils zu Lichtflecken im Verkehrsraum abbildbar sind zur Bildung einer vorgegebenen Lichtverteilung mit einer Hell-Dunkel-Grenze.The The invention relates to a headlight for vehicles with a plurality of LED light sources used to form an LED array are arranged grouped on a common substrate and the each emit a partial light bundle, and with a the LED field upstream optical unit, so that the partial light bundle the LED light sources can each be imaged to light spots in the traffic area are to form a given light distribution with a cut-off line.
Aus
der
Aufgabe der vorliegenden Erfindung ist es daher, einen Scheinwerfer für Fahrzeuge mit einer Mehrzahl von LED-Lichtquellen derart weiterzubilden, dass auf einfache Weise eine homogenere Lichtverteilung erzeugt wird, ohne dass eine Beeinträchtigung der Hell-Dunkel-Grenze der Lichtverteilung eintritt.task The present invention is therefore a headlamp for Develop vehicles with a plurality of LED light sources in such a way that easily generates a more homogeneous light distribution will, without affecting the cut-off line the light distribution occurs.
Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass der Optikeinheit und/oder dem LED-Feld eine solche Feinstrukturfläche mit einer Mehrzahl von in eine Vorzugsrichtung verlaufenden Strukturelementen zugeordnet ist, dass zumindest ein Teil der die Lichtverteilung bildenden Lichtflecken in horizontaler Richtung aufgeweitet sind, so dass bei Projektion der Lichtverteilung auf einen Messschirm seitliche Ränder benachbarter Lichtflecken aneinander liegen oder sich überdecken.to Solution to this problem is the invention in connection with the preamble of claim 1, characterized in that the optical unit and / or the LED field such a fine structure surface with a plurality of structural elements extending in a preferred direction is associated with that at least part of the light distribution forming light spots are widened in the horizontal direction, so that when projecting the light distribution on a screen lateral edges of adjacent light spots lie against one another or cover up.
Der besondere Vorteil der Erfindung besteht darin, dass durch eine Feinstrukturfläche mit entlang einer Vorzugsrichtung verlaufenden Strukturelementen ein Schließen von unerwünschten Lichtlücken in einer Lichtverteilung bzw. eine Homogenisierung der Lichtverteilung unterhalb der Hell-Dunkel-Grenze ermöglicht wird. Darüber hinaus wird einer unerwünschten Farbsaumentstehung im Bereich der Hell-Dunkel-Grenze sowie in Randbereichen der Lichtverteilung entgegengewirkt.Of the particular advantage of the invention is that by a fine structure surface with along a preferred direction extending structural elements a closing of unwanted light gaps in a light distribution or a homogenization of the light distribution below the cut-off line. About that In addition, an undesirable Farbsaumentstehung in the area the cut-off line and in peripheral areas of the light distribution counteracted.
Nach einer bevorzugten Ausführungsform der Erfindung erstrecken sich Strukturelemente der Feinstrukturfläche entlang einer Geraden oder einer Kurve, wobei die Kurve – wie die Gerade – bei einer Projektion in einer vertikalen Ebene in einer vertikalen Vorzugsrichtung verläuft. Hierdurch ist sichergestellt, dass die erzeugten Lichtflecken ausschließlich in horizontaler Richtung, aber nicht in vertikaler Richtung aufgeweitet werden.To a preferred embodiment of the invention Structural elements of the fine structure surface along a Straight line or a curve, with the curve - like the straight line - at a projection in a vertical plane in a vertical preferred direction runs. This ensures that the generated Light spots only in the horizontal direction, but not be widened in the vertical direction.
Nach einer Weiterbildung der Erfindung sind die Strukturelemente gleichförmig ausgebildet einerseits und nebeneinander oder beabstandet zueinander angeordnet andererseits. Hierdurch weist die Feinstrukturfläche eine regelmäßige Struktur auf, die in einer senkrecht zur Vorzugsrichtung verlaufenden Richtung vorzugsweise eine periodische Formgebung aufweist.To In a further development of the invention, the structural elements are uniform formed on the one hand and next to each other or spaced from each other arranged on the other hand. This indicates the fine structure surface a regular structure in a vertical to the preferred direction extending direction preferably a periodic Shaping has.
Nach einer Weiterbildung der Erfindung ist die Feinstrukturfläche auf einer optisch wirksamen Oberfläche eines Optikelementes der Optikeinheit aufgebracht. Beispielsweise kann die Feinstrukturfläche als Folie nachträglich auf die Oberfläche des Optik elementes aufgeklebt werden. Alternativ kann bereits bei Formgebung des Optikelementes die Feinstrukturfläche erzeugt werden. Die Feinstrukturfläche weist eine gewisse Welligkeit bzw. Rifflung auf, die ein Aneinandersetzen bzw. Überdecken von Lichtflecken in horizontaler Richtung ermöglicht.To a development of the invention is the fine structure surface on an optically effective surface of an optical element applied to the optical unit. For example, the fine structure surface as a foil subsequently on the surface of the Optic elements are glued on. Alternatively, already at shaping the Optikelementes the fine structure surface are generated. The fine structure surface has a certain waviness or Rifflung auf, which a confronting or covering of light spots in the horizontal direction.
Nach einer Weiterbildung der Erfindung kann eine Feinstrukturfläche auch eine Flachseite einer transparenten Platte bilden, die zwischen dem LED-Feld und der Optikeinheit angeordnet ist. Vorteilhaft können hierdurch herkömmliche Scheinwerfer durch Integration des durch die transparente Platte gebildeten Zusatzbauteils nachgerüstet werden.To A development of the invention may be a fine structure surface Also, make a flat side of a transparent plate between the LED field and the optical unit is arranged. Can be advantageous As a result, conventional headlights through integration of the retrofitted by the additional component formed by the transparent plate become.
Nach einer Weiterbildung der Erfindung können die Feinstrukturelemente im Querschnitt sinus-, kissen- oder sägezahnförmig ausgebildet sein. Sie bilden vorzugsweise eine Strukturierung im Mikrobereich. Hierdurch wird ein Verwischen der Lücken in horizontaler Richtung und somit eine homogenere Lichtverteilung ermöglicht.According to a development of the invention, the fine structure elements may be sinusoidal, pillowed or sawtooth-shaped in cross-section. They preferably form a structuring in the micro range. This will blur the gaps in horizontal direction and thus allows a more homogeneous light distribution.
Nach einer Weiterbildung der Erfindung ist die Anzahl und/oder Erhabenheit der Strukturelemente in einem zentralen Abschnitt der Feinstrukturfläche bzw. des Optikelementes kleiner als in einem benachbarten seitlichen Abschnitt desselben. Es wird somit eine quasi-periodische Oberflächenstruktur gebildet, sodass ein gezieltes „Verwischen" der Lichtlücken innerhalb der Lichtverteilung bewirkt werden kann.To a development of the invention is the number and / or grandeur the structural elements in a central portion of the fine structure surface or of the optical element smaller than in an adjacent lateral Section of the same. It thus becomes a quasi-periodic surface structure formed, so that a specific "blurring" of the gaps in light can be effected within the light distribution.
Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further Advantages of the invention will become apparent from the other dependent claims.
