Description

Die Erfindung betrifft ein Projektionsmodul für einen Kraftfahrzeugscheinwerfer, welches Projektionsmodul Folgendes umfasst:

  • eine erste Lichtquelle und eine zweite Lichtquelle,
  • eine Strahlenblende, welche eingerichtet ist, bei einer bestimmungsgemäßen Verwendung des Projektionsmoduls in einem eingebauten Kraftfahrzeugscheinwerfer horizontal angeordnet zu sein, und eine optisch relevante Blendenkante zur Erzeugung einer asymmetrischen Hell-Dunkel-Grenze umfasst, wobei die erste Lichtquelle an einer Oberseite der Strahlenblende angeordnet ist und in Kombination mit der optisch relevanten Blendenkante der Strahlenblende zur Erzeugung einer Abblendlichtverteilung mitwirkt, und wobei die zweite Lichtquelle an einer Unterseite der Strahlenblende angeordnet ist und zur Erzeugung einer Fernlichtverteilung mitwirkt,
  • zumindest eine Projektionslinse mit einer optischen Achse und einer Brennfläche zum Projizieren einer Lichtverteilung in eine Hauptabstrahlrichtung vor das Projektionsmodul, wobei die Blendenkante der Strahlenblende zur Erzeugung einer scharfen Hell-Dunkel-Grenze im Wesentlichen in der Brennfläche der Projektionslinse angeordnet ist, und wobei die optische Achse mit der Hauptabstrahlrichtung zusammen fällt.
The invention relates to a projection module for a motor vehicle headlight, which projection module comprises the following:
  • a first light source and a second light source,
  • a beam shield, which is set up to be arranged horizontally when the projection module is used as intended in a built-in motor vehicle headlight, and includes an optically relevant screen edge for generating an asymmetrical light-dark boundary, the first light source being arranged on an upper side of the beam shield and in combination with the optically relevant screen edge of the beam screen contributes to generating a low beam distribution, and wherein the second light source is arranged on an underside of the beam screen and contributes to generating a high beam distribution,
  • at least one projection lens with an optical axis and a focal surface for projecting a light distribution in a main emission direction in front of the projection module, wherein the diaphragm edge of the beam diaphragm is arranged essentially in the focal surface of the projection lens to produce a sharp light-dark boundary, and wherein the optical axis coincides with the main emission direction.

Es kann sich beispielsweise um ein Projektionsmodul zur Realisierung eines Fernlichts bzw. einer Fernlichtverteilung handeln. Dieses soll eine geteilte Fernlichtwolke für linken und rechten Scheinwerfer abbilden, welche im Ausblendfall auseinander geschwenkt werden kann. Um dies zu erreichen werden auf der Strahlenblende, die horizontal im Modul angeordnet ist, senkrechte Laschen bzw. eine Zusatzblende, welche vertikal angeordnet ist, angeordnet.For example, it can be a projection module for realizing a high beam or a high beam distribution. This should depict a divided high beam cloud for the left and right headlights, which can be pivoted apart when faded out. In order to achieve this, vertical tabs or an additional screen, which is arranged vertically, are arranged on the radiation screen, which is arranged horizontally in the module.

Unter einer Lichtfunktion wird dabei die Erzeugung einer gesetzlich vorgegebenen Lichtverteilung durch das Projektionsmodul bzw. einem Kraftfahrzeugscheinwerfer verstanden. Beispiele für solche Lichtverteilungen sind die Abblendlichtverteilung und die Fernlichtverteilung.A light function is understood to mean the generation of a legally specified light distribution by the projection module or a motor vehicle headlight. Examples of such light distributions are the low-beam light distribution and the high-beam light distribution.

Durch Steuerung erfolgt zum Beispiel eine automatische Fernlichtschaltung mit einer Teilfernlichtfunktion, die vorgesehen ist, dass trotz vorausfahrendem und/oder entgegenkommenden Verkehr ein Teil der Fernlichtverteilung aktiviert bliebt. Dabei erzeugt das Projektionsmodul bzw. der Kraftfahrzeugscheinwerfer bzw. ein Kraftfahrzeugscheinwerfersystem dort, wo sich andere Verkehrsteilnehmer befinden, einen nicht beleuchteten Teilbereich in der Fernlichtverteilung, damit die anderen Verkehrsteilnehmer nicht geblendet werden, beispielsweise werden - bei Vorhandensein eines linken und eines rechten Scheinwerfers, welche jeweils einen Teil einer gemeinsamen Fernlichtverteilung erzeugen - diese Teile auseinandergeschwenkt, wobei zwischen diesen Teilen ein nicht beleuchteter Bereich entsteht, in welchem der entgegenkommenden bzw. vorausfahrende Verkehr positioniert ist. Wenn nun der entgegenkommende bzw. vorausfahrende Verkehrsteilnehmer beispielsweise sehr nahe am Kraftfahrzeug befindet, kann der nicht beleuchtete Bereich nicht mehr durch ein Auseinanderschwenken der Teile der Fernlichtverteilung vergrößert werden, da der Schwenkwinkel zu groß ist. In einem solchen Fall muss einer der Scheinwerfer, beispielsweise der linke Scheinwerfer, ausgeschaltet werden, damit der nicht beleuchtete Bereich vergrößert werden kann.For example, automatic high beam switching with a partial high beam function takes place by control, which is provided so that a part of the high beam distribution remains activated despite preceding and/or oncoming traffic. The projection module or the motor vehicle headlight or a motor vehicle headlight system generates a non-illuminated sub-area in the high beam distribution where other road users are located, so that other road users are not dazzled, for example - if there is a left and a right headlight, which respectively generate part of a common high beam distribution - these parts are pivoted apart, with an unilluminated area being created between these parts, in which the oncoming or preceding traffic is positioned. If the oncoming or preceding road user is, for example, very close to the motor vehicle, the non-illuminated area can no longer be enlarged by swiveling the parts of the high beam distribution apart, since the swivel angle is too large. In such a case, one of the headlights, such as the left headlight, must be turned off to increase the unlit area.

Eine solche, teilweise abgeschattete Fernlichtverteilung wird im Folgenden als Teilfernlichtverteilung bezeichnet, welche in der Regel von einem einzigen Kraftfahrzeugscheinwerfer bzw. dem Projektionsmodul in diesem Kraftfahrzeugscheinwerfer erzeugt wird. Derartige Projektionsmodule sind in unterschiedlichen Ausführungen in Kraftfahrzeugscheinwerfern realisiert bzw. umgesetzt.Such a partially shaded high beam distribution is referred to below as a partial high beam distribution, which is generally generated by a single motor vehicle headlight or the projection module in this motor vehicle headlight. Such projection modules are realized or implemented in different versions in motor vehicle headlights.

Diese sorgen dafür, dass jeweils eine Hälfte der Fernlichtwolke beispielsweise bei 3,5° an der H-H Line abgeschnitten wird. Bei den gesetzlichen Anforderungen wird jedoch kein Unterschied gemacht, da eine Einzelerfüllung der Scheinwerfer erforderlich ist, d.h. es müssen einige Punkte und Linien der gesetzlichen Auswertung im Fernlicht auch dort erfüllt werden, wo durch Abschottung der aufgestellten Zusatzblenden kein Licht hinkommen kann.These ensure that half of the high beam cloud is cut off at 3.5° on the H-H Line, for example. However, no difference is made with the legal requirements, since the headlights must meet individual requirements, i.e. some points and lines of the legal evaluation in the high beam must also be fulfilled where no light can reach due to the isolation of the additional screens that have been set up.

Bei der Auswertung für die ECE-AFS Norm stellt dies kein Problem dar, weil hier der linke und der rechte Scheinwerfer zusammengezählt und dann die Lichtstärke halbiert gemessen wird. Um eine Zulassung dieser ADB-Variante mit Teilfernlicht auch in China (CCC-Norm) und in den USA (FMVSS) zu erlangen, werden die Scheinwerfer allerdings nicht mehr zusammen ausgewertet, wie bei Auswertung in Bezug auf die ECE-Norm, sondern es ist eine Einzelerfüllung der jeweiligen Scheinwerfer vorgeschrieben.This does not pose a problem for the evaluation for the ECE-AFS standard, because here the left and right headlights are added together and the light intensity is then halved. However, in order to obtain approval for this ADB variant with partial high beam in China (CCC standard) and in the USA (FMVSS), the headlights will no longer be used evaluated together, as with the evaluation in relation to the ECE standard, but individual fulfillment of the respective headlights is required.

EP 2 982 901 A1 offenbart ein allgemein bekanntes Projektionsmodul für einen KFZ-Scheinwerfer. Es ist eine Aufgabe der Erfindung ein verbessertes Projektionslichtmodul bereitzustellen. Diese Aufgabe wird dadurch gelöst, dass das Projektionsmodul eine Zusatzblende umfasst, welche eingerichtet ist, bei einer bestimmungsgemäßen Verwendung des Projektionsmoduls in einem Kraftfahrzeugscheinwerfer vertikal unterhalb der Strahlenblende angeordnet zu sein und eine sich vertikal erstreckende erste optisch relevante Blendenkante aufweist, welche von der optischen Achse beabstandet angeordnet ist, wobei die erste optisch relevante Blendenkante eingerichtet ist, Licht von der zweiten Lichtquelle teilweise abzuschatten, sodass eine Teilfernlichtverteilung erzeugbar ist, und wobei die Zusatzblende einen Anlageabschnitt aufweist, an welchem die Zusatzblende an der Strahlenblende anliegt, wobei die erste optisch relevante Blendenkante in vertikaler Erstreckung in Richtung der Strahlenblende ein Ende aufweist, welches einen Abstand zur Strahlenblende aufweist, und wobei die Zusatzblende eine zweite optisch relevante Blendenkante aufweist, welche sich ausgehend von dem Ende der ersten optisch relevanten Blendenkante bis zum Anlageabschnitt erstreckt, wobei ein Abstand der zweiten optisch relevanten Blendenkante in vertikaler Richtung zur Strahlenblende einen Spalt definiert, welcher Spalt in Kombination mit der zweiten Lichtquelle eingerichtet ist, ein Segment in der Teilfernlichtverteilung zu erzeugen. EP 2 982 901 A1 discloses a well-known projection module for a motor vehicle headlight. It is an object of the invention to provide an improved projection light module. This object is achieved in that the projection module comprises an additional screen which is set up to be arranged vertically below the beam screen when the projection module is used as intended in a motor vehicle headlight and has a vertically extending first optically relevant screen edge which is spaced from the optical axis is arranged, wherein the first optically relevant screen edge is set up to partially shade light from the second light source, so that a partial high beam distribution can be generated, and wherein the additional screen has a contact section on which the additional screen rests on the beam screen, the first optically relevant screen edge in vertical extension in the direction of the beam stop has an end which is at a distance from the beam stop, and wherein the additional stop has a second optically relevant stop edge which extends from the end of the first optically relevant stop edge to the contact section, with a distance between the second optically relevant aperture edge in the vertical direction to the beam aperture defines a gap, which gap is set up in combination with the second light source to generate a segment in the partial high beam distribution.

Generell beziehen sich im Weiteren die Begriffe hinsichtlich eines Ortes oder einer Orientierung, wie beispielsweise "horizontal", "vertikal", "in horizontaler Richtung", "in vertikaler Richtung", "oben", "unten", "vorne", "hinten", "darunter", "darüber" etc. auf eine ordnungsgemäße Einbaulage des gegenständlichen Projektionsmoduls in einem Kraftfahrzeugscheinwerfer.In general, the terms refer to a location or an orientation, such as "horizontal", "vertical", "in the horizontal direction", "in the vertical direction", "top", "bottom", "front", "back". ", "underneath", "above" etc. for a proper installation position of the projection module in question in a motor vehicle headlight.

Die Zusatzblende ist mit einem Spalt bzw. Schlitz versehen. Dieser Spalt ermöglicht in Verbindung mit einer Anhebung bzw. Absenkung eine weltweite Zulassung des Teilfernlichts bzw. der Teilfernlichtverteilung.The additional screen is provided with a gap or slot. This gap, in conjunction with an increase or reduction, enables the partial high beam or the partial high beam distribution to be approved worldwide.

Für Linksverkehr kann die Anordnung um die Sagittalebene gespiegelt angeordnet sein.For left-hand traffic, the arrangement can be mirrored about the sagittal plane.

Es kann vorgesehen sein, dass die erste optisch relevante Blendenkante der Zusatzblende eingerichtet ist, auf einem Messschirm die erzeugbare Fernlichtverteilung bei -5° bis -1°, vorzugsweise bei - 3,5°, horizontal abzuschatten.Provision can be made for the first optically relevant aperture edge of the additional aperture to be set up to shade horizontally the main beam distribution that can be generated at −5° to −1°, preferably at −3.5°, on a measuring screen.

Es kann vorgesehen sein, dass der Spalt eingerichtet ist, ein Segment in der Teilfernlichtverteilung zu erzeugen, welches Segment sich horizontal von - 3,5° bis maximal -12°, vorzugsweise bis maximal -6°, vorzugsweise bis maximal -5°, erstreckt, und sich vertikal bis 2°, vorzugsweise bis 1°, vorzugsweise bis 0,2°, auf einem Messschirm erstreckt.It can be provided that the gap is set up to generate a segment in the partial high beam distribution, which segment extends horizontally from -3.5° to a maximum of -12°, preferably to a maximum of -6°, preferably to a maximum of -5° , and extends vertically up to 2°, preferably up to 1°, preferably up to 0.2° on a measuring screen.

Hierbei handelt es sich um Raumwinkel, sodass der Abstand des Messschirms prinzipiell nicht relevant ist.These are solid angles, so the distance of the measuring screen is not relevant in principle.

Es kann vorgesehen sein, dass der Messschirm 25m von dem Projektionsmodul entfernt angeordnet ist.Provision can be made for the measuring screen to be arranged 25m away from the projection module.

Es kann vorgesehen sein, dass die Strahlenblende und die Zusatzblende eine in sich starre Verbundblende bilden.Provision can be made for the radiation stop and the additional stop to form an inherently rigid composite stop.

Unter "starr" wird dabei verstanden, dass die Strahlenblende und die Zusatzblende derart miteinander verbunden sind, dass Relativbewegungen möglichst verhindert bzw. nicht möglich sein sollen.“Rigid” is understood to mean that the radiation stop and the additional stop are connected to one another in such a way that relative movements should be prevented or not possible as far as possible.

Es kann vorgesehen sein, dass die Brennfläche der Projektionslinse gekrümmt ist, wobei der Verlauf der optisch relevanten Blendenkante der Strahlenblende im Wesentlichen der gekrümmten Brennfläche folgt.Provision can be made for the focal surface of the projection lens to be curved, with the course of the optically relevant diaphragm edge of the radiation diaphragm essentially following the curved focal surface.

Es kann vorgesehen sein, dass die Zusatzblende orthogonal auf die optische Achse der Projektionslinse angeordnet ist.Provision can be made for the additional diaphragm to be arranged orthogonally to the optical axis of the projection lens.

Es kann vorgesehen sein, dass die erste optisch relevante Blendenkante der Zusatzblende in Richtung der optischen Achse der Projektionslinse beabstandet ist, wobei der Abstand 1mm, vorzugsweise 8/10 mm, groß ist.It can be provided that the first optically relevant screen edge of the additional screen is spaced apart in the direction of the optical axis of the projection lens, the distance being 1 mm, preferably 8/10 mm.

Es sei angemerkt, dass mit "Abstand" auch ein solcher Abstand inbegriffen ist, bei welchem die erste optisch relevante Blendenkante der Zusatzblende in Richtung der optischen Achse zur oder entgegen der Anordnungsrichtung der Projektionslinse beabstandet ist.It should be noted that "distance" also includes such a distance at which the first optically relevant aperture edge of the additional aperture is spaced in the direction of the optical axis to or opposite to the arrangement direction of the projection lens.

Durch einen solchen Abstand soll die Hell-Dunkel-Grenze der Teilfernlichtverteilung bzw. des erzeugbaren Segments in der Teilfernlichtverteilung dahingehend verbessert werden, dass entstehende Farbsäume verringert werden sollen. Dabei gilt, dass je größer der oben genannte Abstand ist, desto bläulicher erscheint der Farbsaum der Hell-Dunkel-Grenze.Such a distance is intended to improve the light-dark boundary of the partial high beam distribution or the segment that can be generated in the partial high beam distribution in such a way that color fringes that occur are intended to be reduced. The rule is that the greater the distance mentioned above, the more bluish the color fringe of the light-dark boundary appears.

Es kann vorgesehen sein, dass die Zusatzblende zumindest ein Loch für eine Signlightlichtverteilung aufweist. Also nur die Erzeugung einzelner Bereiche bzw. Punkte für die Signlightlichtverteilung vorgesehen ist.It can be provided that the additional screen has at least one hole for a signal light distribution. So only the generation of individual areas or points for the signal light distribution is provided.

Es kann vorgesehen sein, dass der Anlageabschnitt als Befestigungsabschnitt ausgebildet ist, an welchem die Zusatzblende an der Strahlenblende befestigt ist.Provision can be made for the contact section to be in the form of a fastening section, on which the additional diaphragm is fastened to the radiation diaphragm.

Fig. 1 zeigt ein Projektionsmodul 10 für einen Kraftfahrzeugscheinwerfer, welches Projektionsmodul 10 eine erste Lichtquelle 110 und eine zweite Lichtquelle 120 sowie eine Strahlenblende 200 umfasst, welche eingerichtet ist, bei einer bestimmungsgemäßen Verwendung des Projektionsmoduls 10 in einem eingebauten Kraftfahrzeugscheinwerfer horizontal angeordnet zu sein, und eine optisch relevante Blendenkante 210 zur Erzeugung einer asymmetrischen Hell-Dunkel-Grenze aufweist. 1 shows a projection module 10 for a motor vehicle headlight, which projection module 10 comprises a first light source 110 and a second light source 120 and a beam shield 200 , which is set up to be arranged horizontally when the projection module 10 is used as intended in a built-in motor vehicle headlight, and an optically relevant Has aperture edge 210 for generating an asymmetrical light-dark boundary.

Die erste Lichtquelle 110 ist dabei an einer Oberseite der Strahlenblende 200 angeordnet und wirkt in Kombination mit der optisch relevanten Blendenkante 210 der Strahlenblende 200 zur Erzeugung einer Abblendlichtverteilung mit, wobei die zweite Lichtquelle 120 an einer Unterseite der Strahlenblende 200 angeordnet ist und zur Erzeugung einer Fernlichtverteilung mitwirkt.The first light source 110 is arranged on an upper side of the beam shield 200 and, in combination with the optically relevant diaphragm edge 210 of the beam shield 200 , contributes to generating a low beam distribution, the second light source 120 being arranged on an underside of the beam shield 200 and to generating a high beam distribution contributes.

Das Projektionsmodul 10 umfasst weiters eine Projektionslinse 300 mit einer optischen Achse A und einer Brennfläche F zum Projizieren einer Lichtverteilung in eine Hauptabstrahlrichtung X vor das Projektionsmodul 10, wobei die Blendenkante 210 der Strahlenblende 200 zur Erzeugung einer scharfen Hell-Dunkel-Grenze im Wesentlichen in der Brennfläche F der Projektionslinse 300 angeordnet ist, und wobei die optische Achse A mit der Hauptabstrahlrichtung X zusammen fällt.The projection module 10 also includes a projection lens 300 with an optical axis A and a focal surface F for projecting a light distribution in a main emission direction X in front of the projection module 10, with the diaphragm edge 210 of the beam diaphragm 200 being essentially in the Focal surface F of the projection lens 300 is arranged, and wherein the optical axis A with the main emission direction X coincides.

Ferner umfasst das Projektionsmodul 10 eine Zusatzblende 200 (in Fig. 1 nicht eingezeichnet), welche in Fig. 2 detaillierter zu sehen ist und eingerichtet ist, bei einer bestimmungsgemäßen Verwendung des Projektionsmoduls 10 in einem Kraftfahrzeugscheinwerfer vertikal unterhalb der Strahlenblende 200 angeordnet zu sein und eine sich vertikal erstreckende erste optisch relevante Blendenkante 410 aufweist, welche von der optischen Achse A beabstandet angeordnet ist. Fig. 2 zeigt die Strahlenblende 200 mit der Zusatzblende 400 in einer Ansicht von schräg hinten und von unten.Furthermore, the projection module 10 includes an additional screen 200 (in 1 not drawn), which in 2 can be seen in more detail and is set up to be arranged vertically below the beam diaphragm 200 when the projection module 10 is used as intended in a motor vehicle headlight and has a vertically extending first optically relevant diaphragm edge 410 which is arranged at a distance from the optical axis A. 2 shows the beam stop 200 with the additional stop 400 in an oblique view from behind and from below.

Die erste optisch relevante Blendenkante 410 ist eingerichtet, Licht von der zweiten Lichtquelle 120 teilweise abzuschatten, sodass eine Teilfernlichtverteilung erzeugbar ist, wobei die Zusatzblende 400 einen Befestigungsabschnitt 430 aufweist, an welchem die Zusatzblende 400 an der Strahlenblende 200 befestigt ist, wobei die Strahlenblende 200 und die Zusatzblende 400 eine in sich starre Verbundblende bilden.The first optically relevant aperture edge 410 is set up to partially shade light from the second light source 120 so that a partial high beam distribution can be generated. wherein the additional screen 400 has a fastening section 430 , on which the additional screen 400 is fastened to the radiation screen 200 , the radiation screen 200 and the additional screen 400 forming an inherently rigid composite screen.

Die erste optisch relevante Blendenkante 410 weist in vertikaler Erstreckung in Richtung der Strahlenblende 200 ein Ende 411 auf, welches Ende 411 einen Abstand zur Strahlenblende 200 aufweist.The first optically relevant aperture edge 410 has an end 411 in the vertical extension in the direction of the beam aperture 200 , which end 411 is at a distance from the beam aperture 200 .

Die Zusatzblende 400 weist weiters eine zweite optisch relevante Blendenkante 420 auf, welche sich ausgehend von dem Ende 411 der ersten optisch relevanten Blendenkante 410 bis zum Befestigungsabschnitt 430 erstreckt, wie in Fig. 4 skizzenhaft dargestellt ist.The additional screen 400 also has a second optically relevant screen edge 420 , which extends from the end 411 of the first optically relevant screen edge 410 to the fastening section 430 , as in FIG 4 is sketched.

Die zweite optisch relevante Blendenkante 420 definiert in einer Projektion bzw. einer Orthogonalprojektion auf die Strahlenblende 200 dabei einen Spalt, welcher Spalt in Kombination mit der zweiten Lichtquelle 120 eingerichtet ist, ein Segment in der Teilfernlichtverteilung zu erzeugen. Mit anderen Worten, der Spalt ist definiert durch den Abstand der zweiten optisch relevanten Blendenkante 420 von der Strahlenblende 200 in vertikaler Richtung bzw. in Erstreckungsrichtung der Zusatzblende 400.The second optically relevant aperture edge 420 defines a gap in a projection or an orthogonal projection onto the beam aperture 200 , which gap is set up in combination with the second light source 120 to generate a segment in the partial high beam distribution. In other words, the gap is defined by the distance between the second optically relevant aperture edge 420 and the radiation aperture 200 in the vertical direction or in the direction in which the additional aperture 400 extends.

Fig. 5 zeigt eine skizzenhafte Ansicht des Projektionsmoduls 10 von unten, wobei zu sehen ist, dass die erste optisch relevante, vertikale Blendenkante 410 und das Ende 411 der Blendenkante 410 beabstandet zur optischen Achse A der Projektionslinse sind, wobei der so gebildete Abstand 440 1mm, vorzugsweise 8/10 mm, groß ist. figure 5 shows a sketchy view of the projection module 10 from below, whereby it can be seen that the first optically relevant, vertical aperture edge 410 and the end 411 of the aperture edge 410 are at a distance from the optical axis A of the projection lens, the distance 440 formed in this way being 1 mm, preferably 8 /10 mm, is large.

Weiters ist zu sehen, dass die Zusatzblende 400 orthogonal auf die optische Achse A der Projektionslinse 300 angeordnet ist.It can also be seen that the additional screen 400 is arranged orthogonally to the optical axis A of the projection lens 300 .

Ferner ist zu sehen, dass die Brennfläche F der Projektionslinse 300 gekrümmt ist, wobei der Verlauf der optisch relevanten Blendenkante 210 der Strahlenblende 200 im Wesentlichen der gekrümmten Brennfläche F folgt.It can also be seen that the focal surface F of the projection lens 300 is curved, with the path of the optically relevant diaphragm edge 210 of the radiation diaphragm 200 essentially following the curved focal surface F.

Fig. 6 zeigt eine Teilfernlichtverteilung aus dem Stand der Technik bzw. von einem Beispiel, in welchem die erste optisch relevante, vertikale Blendenkante 410 der Zusatzblende 400 in vertikaler Erstreckung ganz bis zur Strahlenblende 200 reichen würde. Dabei ist zu sehen, dass die erste optisch relevante Blendenkante der Zusatzblende die Fernlichtverteilung bei - 3,5° horizontal abschattet 6 shows a partial high beam distribution from the prior art or from an example in which the first optically relevant, vertical screen edge 410 of the additional screen 400 would extend vertically all the way to the beam screen 200 . It can be seen that the first optically relevant panel edge of the additional panel shades the high beam distribution horizontally at - 3.5°

Fig. 7 zeigt eine Teilfernlichtverteilung, welche von dem erfindungsgemäßen Projektionsmodul 10 erzeugbar ist, wobei der zuvor erwähnte Spalt, der durch die Zusatzblende definiert wird, eingerichtet ist, ein Segment 500 in der Teilfernlichtverteilung zu erzeugen, welches Segment 500 sich horizontal von - 2° bis maximal -12°, vorzugsweise bis maximal -6°, vorzugsweise bis maximal -5°, vorzugsweise genau bis maximal -3,5° erstreckt, und sich vertikal bis 2°, vorzugsweise bis 1°, vorzugsweise bis 0,2°, auf dem Messschirm erstreckt. 7 shows a partial high beam distribution which can be generated by the projection module 10 according to the invention, the previously mentioned gap, which is defined by the additional screen, being set up to generate a segment 500 in the partial high beam distribution, which segment 500 extends horizontally from -2° to a maximum of - 12°, preferably up to a maximum of -6°, preferably up to a maximum of -5°, preferably exactly up to a maximum of -3.5°, and extends vertically up to 2°, preferably up to 1°, preferably up to 0.2° on the measuring screen extends.
