Description

Die Erfindung betrifft einen Scheinwerfer für Fahrzeuge nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a headlamp for vehicles according to the preamble of patent claim 1.

Aus der DE 10 2005 031 776 A1 ist ein Scheinwerfer für Fahrzeuge bekannt, der zum einen eine Lichtquelle und zum anderen eine Lichtführungseinheit zur Erzeugung einer vorgegebenen Lichtverteilung mit einer Hell-Dunkel-Grenze aufweist. Die Lichtführungseinheit weist ein linsenförmiges Optikelement auf, das in seiner Relativlage zu der Lichtquelle in Abhängigkeit von der aktuellen Temperatur derart verändert wird, dass eine die gesetzlichen Vorgaben nicht überschreitende Hell-Dunkel-Grenze erzeugt wird. Insbesondere kann hierdurch eine wellenlängen- und temperaturbedingte Verlagerung der Hell-Dunkel-Grenze infolge von Dispersionseffekten verringert bzw. vermieden werden. Allerdings sind hierzu mechanische und elektronische Mittel erforderlich, wie beispielsweise ein Temperatursensor zur Ermittlung der aktuellen Temperatur, eine Stelleinheit zur Verstellung des linsenförmigen Optikelementes und eine elektronische Steuereinheit zur Bestimmung des Stellweges, um den das linsenförmige Optikelement verstellt wird.From the DE 10 2005 031 776 A1 a headlamp for vehicles is known, which has on the one hand a light source and on the other a light guide unit for generating a predetermined light distribution with a cut-off line. The light guide unit has a lens-shaped optical element, which is changed in its relative position to the light source as a function of the current temperature such that a legal limit does not exceed the bright-dark boundary is generated. In particular, this can reduce or avoid wavelength and temperature-related shifting of the cut-off line due to dispersion effects. However, this mechanical and electronic means are required, such as a temperature sensor for determining the current temperature, an actuator for adjusting the lens-shaped optical element and an electronic control unit for determining the travel by which the lens-shaped optical element is adjusted.

Aus der DE 10 2004 062 913 A1 ist ein Scheinwerfer für Fahrzeuge mit einer Lichtquelle und einer Lichtführungseinheit zur Erzeugung einer vorgegebenen Lichtverteilung mit einer Hell-Dunkel-Grenze bekannt. Die Lichtführungseinheit weist ein linsenförmiges Optikelement auf, das in einem oberen Bereich eine Brennweite aufweist, die kleiner ist als eine weitere Brennweite des unteren Bereiches. Darüber hinaus ist das linsenförmige Optikelement in Richtung der optischen Achse um mindestens -1 mm verschoben, so dass eine Korrektur der farblichen Dispersion des linsenförmigen Optikelementes erreicht werden kann.From the DE 10 2004 062 913 A1 is a headlamp for vehicles with a light source and a light guide unit for generating a predetermined light distribution with a cut-off. The light guide unit has a lens-shaped optical element which has a focal length in an upper region which is smaller than a further focal length of the lower region. In addition, the lens-shaped optical element is shifted in the direction of the optical axis by at least -1 mm, so that a correction of the color dispersion of the lens-shaped optical element can be achieved.

Aus der DE 43 29 332 A1 , EP 0 325 254 A1 und GB 1 248 600 A sind weitere Maßnahmen zur Verringerung der Dispersion eines linsenförmigen Optikelementes bekannt.From the DE 43 29 332 A1 . EP 0 325 254 A1 and GB 1 248 600 A Further measures for reducing the dispersion of a lens-shaped optical element are known.

Aufgabe der vorliegenden Erfindung ist es, einen Scheinwerfer für Fahrzeuge derart weiterzubilden, dass eine wellenlängen- und/oder temperaturbedingte Verlagerung der Hell-Dunkel-Grenze einer Lichtverteilung auf einfache Weise verringert bzw. vermieden wird.Object of the present invention is to develop a headlamp for vehicles such that a wavelength and / or temperature-induced shift in the light-dark boundary of a light distribution is reduced or avoided in a simple manner.

Zur Lösung dieser Aufgabe weist die Erfindung die Merkmale des Patentanspruchs 1 auf.To solve this problem, the invention has the features of claim 1.

Der besondere Vorteil der Erfindung besteht darin, dass insbesondere temperaturbedingte Dispersionseffekte verringert bzw. vermieden werden können, wobei eine weitgehend farbneutrale Hell-Dunkel-Grenze erzeugt wird. In einem breiten Temperaturbereich kann somit eine Hell-Dunkel-Grenze in einer festgelegten Lage erzeugt werden.The particular advantage of the invention is that, in particular, temperature-induced dispersion effects can be reduced or avoided, with a largely color-neutral light-dark boundary being produced. In a wide temperature range, a bright-dark boundary can thus be generated in a fixed position.

Grundgedanke der Erfindung ist es, solche an dem linsenförmigen Optikelement in einem Randbereich gebrochene spektrale Teillichtstrahlen zu einem gemeinsamen Brennpunkt bzw. bei dreidimensionaler Betrachtung zu einer gemeinsamen Brennlinie zusammenzuführen, die in einem oberhalb der optischen Achse des Optikelementes unter einem relativ kleinen Brechungswinkel und unterhalb der optischen Achse um einen relativ großen Brechungswinkel gebrochen werden. Hierdurch können für den unerwünschten Farbsaumeffekt an der Hell-Dunkel-Grenze verantwortliche und die Lage der Hell-Dunkel-Grenze bestimmende Randstrahlen des Lichtstrahlenspektrums zusammengeführt werden. Die anderen spektralen Teillichtstrahlen im Randbereich des linsenförmigen Optikelementes verlaufen jeweils im Vertikalschnitt gesehen unterhalb der zusammenlaufenden spektralen Teillichtstrahlen unterschiedlicher Farbe.The basic idea of the invention is to combine such spectral partial light beams refracted at the lenticular optical element in an edge region into a common focal point or three-dimensional view into a common focal line which is at a relatively small refraction angle and below the optical axis in one above the optical axis of the optical element Axis be broken by a relatively large angle of refraction. In this way, edge rays of the light beam spectrum which are responsible for the unwanted color fringe effect at the light-dark boundary and determine the position of the light-dark boundary can be brought together. The other partial spectral light beams in the edge region of the lenticular optical element each run in vertical section below the converging spectral partial light beams of different colors.

Nach der Erfindung liegen die unter einem relativ kleinen Brechungswinkel gebrochenen spektralen Teillichtstrahlen des oberen Randbereiches des Optikelementes in einem roten Wellenlängenbereich. Die unter einem relativ großen Brechungswinkel im unteren Bereich des Optikelementes gebrochenen spektralen Teillichtstrahlen liegen in einem blauen Wellenlängenbereich. Diese roten und blauen Teillichtstrahlen bilden Randstrahlen eines Lichtstrahlenspektrums, wobei sie jeweils einen oberen Randstrahlenbereich des Strahlenspektrums bilden. Hierdurch ist sichergestellt, dass die maßgeblichen Randstrahlen in einem gemeinsamen Brennpunkt zusammenlaufen, während die weiteren spektralen Teillichtstrahlen um einen Differenzwinkel unterhalb der entsprechenden Teillichtstrahlen verlaufen und somit nicht zu einer Blendung beitragen können. Vorteilhaft ermöglicht die erfindungsgemäße Überlagerung (additive Farbmischung) von Rot- und Blauanteilen der Lichtstrahlung eine Vergrößerung des "weißen" Mischbereiches. Der Temperatureinsatzbereich des vorzugsweise aus Kunststoffmaterial hergestellten linsenförmigen Optikelementes, in dem sich die Hell-Dunkel-Grenze innerhalb der gesetzlichen Anforderungen verändert (insbesondere Lage und Farbe), wird somit größer. Dadurch vergrößert sich ebenfalls die Justagetoleranz bzw. eine Justage kann sogar gegebenenfalls vermieden werden.According to the invention, the spectral partial light beams of the upper edge region of the optical element which are refracted at a relatively small refraction angle lie in a red wavelength range. The partial spectral light beams which are refracted at a relatively large refraction angle in the lower region of the optical element lie in a blue wavelength range. These red and blue partial light beams form marginal rays of a light beam spectrum, wherein they each form an upper marginal radiation area of the beam spectrum. This ensures that the relevant marginal rays converge in a common focal point, while the other spectral partial light rays run through a differential angle below the corresponding partial light beams and thus can not contribute to glare. Advantageously, the superposition according to the invention (additive color mixing) of red and blue portions of the light radiation enables an enlargement of the "white" mixing area. The temperature application range of the lens-shaped optical element, preferably made of plastic material, in which the light-dark boundary changes within the legal requirements (in particular position and color), thus becomes larger. This also increases the adjustment tolerance or an adjustment can even be avoided if necessary.

Das erfindungsgemäße linsenförmige Optikelement kann zum einen in einem Scheinwerfer mit einer LED-Leuchteinheit als Lichtquelle eingesetzt werden und zum anderen in einem Projektionsscheinwerfer, der mit einem Reflektor und einer zusätzlichen Blende nach dem Projektionsprinzip arbeitet. Vorteilhaft ermöglicht die Erfindung einen im Vergleich zum Stand der Technik Platz sparenden und vereinfachten Aufbau des Scheinwerfers, wobei unerwünschten Dispersionseffekte im Scheinwerfer verringert werden.The lenticular optical element according to the invention can be used on the one hand in a headlamp with an LED light unit as the light source and on the other hand in a projection headlamp, which works with a reflector and an additional aperture on the projection principle. Advantageously, the invention allows a space-saving and simplified design of the headlamp compared to the prior art, whereby undesirable dispersion effects in the headlamp are reduced.

Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further advantages of the invention will become apparent from the further subclaims.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert.An embodiment of the invention will be explained in more detail with reference to the drawings.

Ein erfindungsgemäßer Scheinwerfer für Kraftfahrzeuge kann beispielsweise als Projektionsscheinwerfer 1 ausgebildet sein, der eine Lichtquelle 2 und eine Lichtführungseinheit 3 zur Erzeugung einer vorgegebenen Lichtverteilung mit einer Hell-Dunkel-Grenze aufweist. Die Lichtführungseinheit 3 ist gebildet durch einen der Lichtquelle 2 zugeordneten Reflektor 4, wobei die Lichtquelle 2 in einem ersten Brennpunkt f1 des Reflektors 4 angeordnet ist. Im Bereich eines zweiten Brennpunktes f2 des Reflektors 4 ist eine Blende 5 angeordnet, deren Kontur mittels eines linsenförmigen Optikelementes 6 abgebildet wird zu einer Hell-Dunkel-Grenze der Lichtverteilung.An inventive headlamp for motor vehicles may be formed, for example, as a projection headlamp 1, which has a light source 2 and a light guide unit 3 for generating a predetermined light distribution with a light-dark boundary. The light guide unit 3 is formed by a reflector 4 associated with the light source 2, wherein the light source 2 is arranged in a first focal point f 1 of the reflector 4. In the region of a second focal point f 2 of the reflector 4, a diaphragm 5 is arranged, whose contour is imaged by means of a lenticular optical element 6 to a light-dark boundary of the light distribution.

Das linsenförmige Optikelement 6 kann aus einem Glas- oder Kunststoffmaterial hergestellt sein.The lenticular optical element 6 may be made of a glass or plastic material.

Bei herkömmlichen linsenförmigen Optikelementen 7 - wie es in Figur 2 dargestellt ist - führt eine in einem Randbereich 8 des Optikelementes 7 erfolgende Brechung eines oberen "weißen" Randstrahls 9 und eines unteren "weißen" Randstrahls 10 zu einer Farbaufspaltung. Die roten Teillichtstrahlen 11 bilden einen Brennpunkt frot, der in Lichtabstrahlrichtung 12 vor einem Brennpunkt f des Optikelementes 7 liegt. Die blauen Teillichtstrahlen 13 bilden eine Brennpunkt fblau, der in Lichtabstrahlrichtung 12 hinter dem Brennpunkt f des Optikelementes 7 liegt. Im Vertikalschnitt des Optikelementes 7 entsteht somit eine Brennlinie zwischen dem Brennpunkt frot und fblau. Dies führt zu unerwünschten Farbeffekten an der Hell-Dunkel-Grenze bzw. zur unerwünschten Blendung weiterer Verkehrsteilnehmer.In conventional lenticular optical elements 7 - as it is in FIG. 2 a refraction of an upper "white" marginal ray 9 and a lower "white" marginal ray 10 in a marginal area 8 of the optic element 7 leads to a color splitting. The red partial light beams 11 form a focal point f red , which lies in the light emission direction 12 in front of a focal point f of the optical element 7. The blue partial light beams 13 form a focal point f blue , which lies in the light emission direction 12 behind the focal point f of the optical element 7. In the vertical section of the optical element 7 thus creates a focal line between the focal point f red and f blue . This leads to undesirable color effects at the cut-off line or to the unwanted dazzling of other road users.

Das erfindungsgemäße linsenförmige Optikelement 6 ist vorzugsweise unter Bildung einer Freiformfläche derart dimensioniert bzw. ausgebildet, dass zum einen rote Teillichtstrahlen 14 der in einem Randbereich 15 oberhalb einer optischen Achse 16 des Optikelementes 6 auftreffenden Lichtstrahlen 17 in einem Brennpunkt fo-Rot = f mit der optischen Achse 16 zusammenlaufen und dass zum anderen blaue Teillichtstrahlen 18 von in einem Randbereich 19 unterhalb der optischen Achse 16 auftreffende Lichtstrahlen 20 in dem gleichen Brennpunkt fu-Blau = f mit der optischen Achse 16 zusammenlaufen. Diese roten Teillichtstrahlen 14 oberhalb der optischen Achse 16 und die blauen Teillichtstrahlen 18 unterhalb der optischen Achse 16 bilden jeweils obere Randstrahlen einer Anzahl von spektralen Teillichtstrahlen.The lens-shaped optical element 6 according to the invention is preferably dimensioned or formed with the formation of a free-form surface in such a way that red partial light beams 14 of the light rays 17 impinging in an edge region 15 above an optical axis 16 of the optical element 6 at a focal point f o -Red = f converging on the optical axis 16 and that, on the other hand, blue partial light beams 18 of light beams 20 incident in an edge region 19 below the optical axis 16 converge with the optical axis 16 at the same focal point f u blue = f. These red partial light beams 14 above the optical axis 16 and the blue partial light beams 18 below the optical axis 16 respectively form upper edge beams of a number of partial spectral beams.

Wie aus Figur 3 ersichtlich ist, schneidet ein blauer unterer Randstrahl 21 der oberhalb der optischen Achse 16 gebrochenen Teillichtstrahlen die optische Achse 16 in einem Bereich zwischen der Hauptebene H des Optikelementes 6 und dem Brennpunkt f. Ein unterer roter Randstrahl 22 der unterhalb der optischen Achse 16 verlaufenden Teillichtstrahlen schneidet die optische Achse 16 in einem in Lichtabstrahlrichtung 12 vor dem Brennpunkt f liegenden Bereich. Der rote Teillichtstrahl 14 wird unter einem Brechungswinkel α1 zu dem Lichtstrahl 17 hin zur optischen Achse 16 gebrochen. Der blaue Teillichtstrahl 18 wird unter einem Brechungswinkel α2 bezogen auf die Lichtstrahlen 20 zu der optischen Achse 16 hin gebrochen. Der Brechungswinkel α1 des roten Teillichtstrahls stimmt vorzugsweise mit der Größe des Brechungswinkels α2 des blauen Teillichtstrahls überein. Die beiden Randstrahlen 21, 22 verlaufen in einem Differenzwinkel zu dem roten Teillichtstrahl 14 bzw. blauen Teillichtstrahl 18 unterhalb derselben, wobei der Randstrahl 21 zu dem Lichtstahl 17 einen Winkel β1 bildet, der größer ist als α1 und wobei der Randstrahl 22 zu dem Lichtstrahl 20 einen Winkel β2 bildet, der kleiner ist als α1, so dass sie zu einer unerwünschten Blendung der Verkehrsteilnehmer nicht beitragen können.How out FIG. 3 a blue lower edge beam 21 of the partial light beams refracted above the optical axis 16 intersects the optical axis 16 in a region between the main plane H of the optical element 6 and the focal point f. A lower red marginal ray 22 of the sub-light beams extending below the optical axis 16 intersects the optical axis 16 in a region lying in front of the focal point f in the light emission direction 12. The red partial light beam 14 is refracted at an angle of refraction α 1 to the light beam 17 towards the optical axis 16. The blue partial light beam 18 is refracted at an angle of refraction α 2 with respect to the light beams 20 towards the optical axis 16. The refraction angle α 1 of the red partial light beam preferably coincides with the size of the refraction angle α 2 of the blue partial light beam. The two marginal rays 21, 22 extend at a differential angle to the red partial light beam 14 or blue partial light beam 18 below the same, wherein the marginal ray 21 to the light beam 17 forms an angle β 1 , which is greater than α 1 and wherein the marginal ray 22 to the Light beam 20 forms an angle β 2 , which is smaller than α 1 , so that they can not contribute to an undesirable glare of road users.

Es versteht sich, dass infolge der unterschiedlichen Brecheigenschaften des Optikelementes 6 oberhalb und unterhalb der optischen Achse 16 die Geometrie derselben oberhalb und unterhalb der optischen Achse 16 unterschiedlich ist. Die unterschiedliche Geometrie bezieht sich insbesondere auf den äußeren Randbereich 15, 19, der bei einer rotationssymmetrischen Ausgestaltung des Optikelementes 6 einen Winkel von 360° um die optische Achse 16 umfasst. Die erfindungsgemäße Korrektur bzw. Manipulation von insbesondere roten Teillichtstrahlen 14 und blauen Teillichtstrahlen 18 ist somit nicht auf den in Figur 3 dargestellten oberen Randbereich 15 und unteren Randbereich 19 beschränkt.It is understood that due to the different breaking properties of the optical element 6 above and below the optical axis 16, the geometry of the same above and below the optical axis 16 is different. The different geometry relates in particular to the outer edge region 15, 19, the in a rotationally symmetrical configuration of the optical element 6 an angle of 360 ° around the optical axis 16 includes. The correction or manipulation according to the invention of, in particular, red partial light beams 14 and blue partial light beams 18 is thus not limited to those in FIG. 3 shown upper edge region 15 and lower edge region 19 limited.

Nach einer nicht dargestellten alternativen Ausführungsform kann das linsenförmige Optikelement 6 auch einer LED-Leuchteinheit (LED-Scheinwerfer) als Lichtquelle zugeordnet sein, wobei die LED-Leuchteinheit aus mindestens einem LED-Leuchtelement bzw. LED-Chip besteht.According to an alternative embodiment, not shown, the lens-shaped optical element 6 may also be associated with an LED lighting unit (LED headlight) as a light source, wherein the LED lighting unit consists of at least one LED lighting element or LED chip.

Beispielsweise kann das linsenförmige Optikelement 6 als Sammellinse, vorzugsweise in einem Projektionsscheinwerfer, oder als eine horizontal und vertikal unterschiedlich streuende Linse, vorzugsweise in einem LED-Scheinwerfer, ausgebildet sein.For example, the lenticular optical element 6 as a converging lens, preferably in a projection headlamp, or as a horizontally and vertically different scattering lens, preferably in an LED headlamp, be formed.

Das erfindungsgemäß ausgebildete linsenförmige Optikelement 6 ermöglicht den Einsatz von Kunststoff-Optikelementen in einem relativ breiten Temperaturbereich.The inventively formed lens-shaped optical element 6 allows the use of plastic optical elements in a relatively wide temperature range.
