Die Erfindung betrifft einen Projektionsscheinwerfer für Kraftfahrzeuge mit einer Lichtquelle, einem Hauptreflektor und einer Lichtscheibe, wobei durch den Hauptreflektor eine optische Achse des Projektionsscheinwerfers definiert wird.The invention relates to a projection headlight for motor vehicles with a light source, a main reflector and a lens, with an optical through the main reflector Axis of the projection headlight is defined.

Aus DE 32 25 609 ist ein Abblendscheinwerfer bekannt, der einen parabolischen Reflektor mit einer optischen Achse und einem Brennpunkt, eine auf der optischen Achse und etwas vor dem Brennpunkt angeordneten Lichtquelle und eine Begrenzungsvorrichtung umfasst, wobei die Begrenzungsvorrichtung einen Teil der aus der Lichtquelle ausgetretenen und zum Reflektor hin wandernden Lichtstrahlen abzufangen vermag, um an dem vom Reflektor zurückgestrahlten Lichtbündel eine Schnittgrenze zu erzeugen. Der Reflektor ist bei diesem Stand der Technik aus zwei Paraboloidabschnitten gleichen Brennpunktes zusammengesetzt, die sich links bzw. rechts von der optischen Achse erstrecken, und der Paraboloidabschnitt, der bei Betrachtung des Reflektors von vorn auf der Seite angeordnet ist, die der vorschriftsgemäß zu befahrenden Straßenseite entspricht, hat eine größere Brennweite als der andere Paraboloidabschnitt.DE 32 25 609 a low beam headlight is known which has a parabolic reflector with an optical axis and a focal point, one on the optical axis and something light source arranged in front of the focal point and a limiting device, wherein the limiting device is a part of the emerged from the light source and for Beams of light migrating towards the reflector can intercept in order to that of the reflector backbeams of light to generate a cut boundary. The reflector is with this State of the art from two paraboloid sections of the same focus composed, which extend to the left or right of the optical axis, and the Paraboloid section that is arranged on the side when viewed from the front of the reflector that corresponds to the street side to be driven according to the regulations has a larger one Focal length than the other paraboloid section.

Aus DE 197 15 693 ist eine Fahrzeugleuchte mit einem Projektorstrahlscheinwerfer bekannt, bei der der Projektorstrahlscheinwerfer eine Lichtquelle, eine Linse und einen Reflektor umfasst, welcher dazu eingerichtet ist, Licht nach vorne durch die Linse zum Erzeugen eines Strahls zu reflektieren. Der Scheinwerfer umfasst ferner eine Abschirmung, welche in dem Lichtweg zwischen dem Reflektor und der Linse angeordnet ist und einen ungleichmäßigen Arbeitsrand aufweist.DE 197 15 693 discloses a vehicle lamp with a projector beam headlight, in which the projector beam headlight has a light source, a lens and a reflector which is configured to forward light through the lens to produce a Reflecting the beam. The headlight also includes a shield, which in the Light path between the reflector and the lens is arranged and an uneven Has working edge.

Aufgabe der vorliegenden Erfindung ist es, die Abstrahlcharakteristik der bekannten Projektionsscheinwerfer für Kraftfahrzeuge zu verbessern und gleichzeitig ihr Erscheinungsbild gefälliger zu gestalten. The object of the present invention is to improve the radiation characteristics of the known Projection headlights for motor vehicles improve and at the same time her Make appearance more pleasing.

Diese Aufgabe wird gelöst durch einen Projektionsscheinwerfer mit den Merkmalen nach Anspruch 1. Bevorzugte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.This task is solved by a projection headlight with the features according to Claim 1. Preferred embodiments of the invention are the subject of Subclaims.

Zur Lösung der Aufgabe wird erfindungsgemäß in dem Leuchtengehäuse gegenüber dem ersten Reflektor ein zweiter Reflektor angeordnet. Der zweite Reflektor wirkt als "Rückreflektor", der einen Teil des von der Lichtquelle abgestrahlten Lichtes auf den ersten "Hauptreflektor" zurückwirft. Dadurch wird der Lichtkegel von der Lichtquelle an seinem Rand begrenzt. Durch die erste Reflexion des Lichtes am Kegelrand durch den Rückreflektor auf den Hauptreflektor und die nachfolgende zweite Reflexion des Lichtes durch den Hauptreflektor wird der Lichtkegel der Lichtquelle zur Seite hin erweitert. Dadurch ist die Abstrahlcharakteristik nicht mehr so "grell", und das Erscheinungsbild des erfindungsgemäßen Projektionsscheinwerfers ist "weicher" im Vergleich zu Scheinwerfern nach dem Stand der Technik.To solve the problem, according to the invention in the lamp housing compared to arranged a first reflector a second reflector. The second reflector acts as "Back reflector" that transmits part of the light emitted by the light source at first "Main reflector" throws back. As a result, the light cone from the light source is at its edge limited. By the first reflection of the light on the cone edge by the back reflector the main reflector and the subsequent second reflection of the light by the The main reflector extends the light cone of the light source to the side. This is the Emission characteristics no longer so "glaring", and the appearance of the Projection headlights according to the invention is "softer" compared to headlights According to the state of the art.

Erfindungsgemäß ist daher der Projektionsscheinwerfer für ein Kraftfahrzeug mit einer Lichtquelle, einem Hauptreflektor und einer Lichtscheibe, wobei durch den Hauptreflektor eine optische Achse definiert wird, gekennzeichnet durch einen Rückreflektor, der zwischen der Lichtquelle und der Lichtscheibe des Scheinwerfers angeordnet ist und eine zu der optischen Achse des Hauptreflektors im wesentlichen zentralsymmetrische Lichtdurchtrittsöffnung aufweist.According to the invention, therefore, the projection headlight for a motor vehicle with a Light source, a main reflector and a lens, being through the main reflector an optical axis is defined, characterized by a back reflector which is between the light source and the lens of the headlamp is arranged and one to the optical axis of the main reflector is essentially symmetrical Has light passage opening.

Insbesondere kann der Rückreflektor in Bezug auf die optische Achse des Hauptreflektors schräg gestellt sein, um an unterschiedliche Anforderungen in Bezug auf Formung des Lichtstrahls bei linkem und rechtem Scheinwerfer angepasst werden zu können.In particular, the back reflector can with respect to the optical axis of the main reflector be inclined to meet different requirements in terms of shaping the Light beam can be adjusted for left and right headlights.

Allgemein kann die Lichtdurchtrittsöffnung des Rückreflektors eine kreisförmige, eine elliptische oder eine im wesentlichen quadratische Form haben. Die spezielle Form der Lichtdurchtrittsöffnung (elliptisch oder quadratisch bzw. rechteckig) kann dabei insbesondere in Abhängigkeit von der Form des Hauptreflektors gewählt werden, so dass der Hauptlichtkegel des Scheinwerfers dem Design der Lichtscheibe entspricht. Darüber hinaus kann in der Lichtdurchtrittsöffnung des Rückreflektors ein optisches Element zur Formung des Hauptlichtstrahls vorgesehen sein. In general, the light passage opening of the rear reflector can be a circular one have an elliptical or a substantially square shape. The special form of Light passage opening (elliptical or square or rectangular) can in particular be selected depending on the shape of the main reflector, so that the The main light cone of the headlamp corresponds to the design of the lens. Furthermore can in the light passage opening of the rear reflector, an optical element for shaping of the main light beam.

Die Form der Reflektorfläche des Rückreflektors kann - von der Lichtquelle aus betrachtet - konvex oder konkav sein. Auf diese Art kann das von der Lichtquelle kommende Licht durch den Rückreflektor ringförmig gebündelt zum Hauptreflektor reflektiert werden (konkav) oder weiter zerstreut werden (konvex). Im ersten Fall erhält man so eine Abstufung in der Intensitätsverteilung des Scheinwerfers, im zweiten Fall ergibt sich eine in etwa stufenlose, gleichförmige Abnahme der Lichtintensität von der optischen Achse nach außen im Lichtkegel.The shape of the reflector surface of the back reflector can - viewed from the light source - be convex or concave. In this way, the light coming from the light source can pass through the back reflector is bundled in a ring to reflect the main reflector (concave) or be further scattered (convex). In the first case you get a gradation in the Intensity distribution of the headlight, in the second case there is an approximately stepless, uniform decrease in light intensity from the optical axis to the outside in Cone of light.

Die Erfindung wird im Folgenden anhand von Beispielen erläutert, wobei Bezug genommen wird auf die beigefügten Zeichnungen.The invention is explained below using examples, reference being made will refer to the attached drawings.

Fig. 1 zeigt einen Scheinwerfer mit einer Ausführungsform des erfindungsgemäßen Rückreflektors im Querschnitt.Fig. 1 shows a headlamp with an embodiment of the invention Cross-section of the rear reflector.

Fig. 2 zeigt eine Ausführungsform des erfindungsgemäßen Rückreflektors in Draufsicht.Fig. 2 shows an embodiment of the rear reflector according to the invention in plan view.

Der in Fig. 1 gezeigte Projektionsscheinwerfer für ein Kraftfahrzeug umfasst eine Lichtquelle 1, die in einem Hauptreflektor 2 positioniert ist. Der Hauptreflektor 2 ist dabei vorzugsweise parabolisch, und die Lichtquelle 1 ist in einem Brennpunkt der Hauptreflektorparabel angeordnet. Der Scheinwerfer wird durch eine Lichtscheibe 3 nach vorne abgeschlossen, so dass die Lichtquelle 1 und weitere, hier nicht betrachtete Elemente des Scheinwerfers vor (mechanischen) Einwirkungen von außen geschützt sind.The projection headlight for a motor vehicle shown in FIG. 1 comprises a light source 1, which is positioned in a main reflector 2. The main reflector 2 is preferred parabolic, and the light source 1 is parabolic at a focal point of the main reflector arranged. The headlight is closed by a lens 3 to the front, so that the light source 1 and further elements of the headlight, not considered here, are in front (Mechanical) external influences are protected.

Durch den Hauptreflektor 2 wird eine optische Achse 5 des Scheinwerfers definiert, auf der die Lichtquelle 1 angeordnet ist. Die Form des Lichtkegels des Scheinwerfers wird wesentlich durch die Form des Hauptreflektors 2 bestimmt. Dabei bilden in der überwiegenden Anzahl der Scheinwerfer die Lichtquelle 1 und ein Zentralabschnitt 4 des Hauptreflektors ein Leuchtenmodul, das als Einheit in den Scheinwerfer eingebaut werden kann. Das Leuchtenmodul umfasst häufig als weitere Elemente Linsen oder sonstige optische Elemente vor der Lichtquelle 1 zur Strahlformung des Lichtkegels. Ein derartiges optisches Element ist in Fig. 1 mit 9 bezeichnet.An optical axis 5 of the headlight is defined by the main reflector 2 on which the light source 1 is arranged. The shape of the light cone of the headlight will essentially determined by the shape of the main reflector 2. Thereby form in the predominant number of headlights the light source 1 and a central section 4 of the The main reflector is a luminaire module that is installed as a unit in the headlamp can. The light module often includes lenses or other elements optical elements in front of the light source 1 for beam shaping of the light cone. Such a thing optical element is designated by 9 in FIG. 1.

Der Einbau des kompletten Leuchtenmoduls in den Scheinwerfer hat insbesondere den Vorteil, dass aufwendige Justagearbeiten bei der Anordnung der Lichtquelle 1 in dem Hauptreflektor 2 entfallen. Das Leuchtenmodul wird lediglich in einen fest in das Fahrzeug eingebauten Außenabschnitt 10 des Hauptreflektors 2 eingesetzt. Die Ausrichtung des Leuchtenmoduls in Bezug auf diesen Außenabschnitt 10 ist dabei nicht so kritisch wie die Ausrichtung der Lichtquelle 1 in Bezug auf achsennähere Abschnitte des strahlformenden Hauptreflektors.The installation of the complete light module in the headlight has in particular Advantage that complex adjustment work in the arrangement of the light source 1 in the Main reflector 2 is omitted. The light module is simply fixed in the vehicle built-in outer portion 10 of the main reflector 2 used. The orientation of the Luminaire module with respect to this outer section 10 is not as critical as that Alignment of the light source 1 with respect to sections of the beam-shaping section closer to the axis Main reflector.

Um die Abstrahlcharakteristik des soweit bekannten Projektionsscheinwerfers für Kraftfahrzeuge zu verbessern und gleichzeitig das Erscheinungsbild des Scheinwerfers gefälliger zu gestalten, wird erfindungsgemäß ein Rückreflektor 6 zwischen der Lichtquelle 1 und der Lichtscheibe 3 des Scheinwerfers angeordnet. Dieser Rückreflektor 6 weist eine zu der optischen Achse 5 des Hauptreflektors 2 im wesentlichen zentralsymmetrische Lichtdurchtrittsöffnung 8 auf, so dass ein achsennaher Anteil des Lichtes von der Lichtquelle 1 ungehindert durch den Rückreflektor aus dem Scheinwerfer austritt. Nur der Anteil des Lichtes, der in einem Winkel von der Lichtquelle abgestrahlt wird, der größer als ein vorgegebener Referenzwinkel ist, wird von dem Rückreflektor 6 zurückgeworfen.The radiation characteristics of the well-known projection headlights for Improve motor vehicles while maintaining the appearance of the headlamp To make it more pleasing, according to the invention, a back reflector 6 between the light source 1 and the lens 3 of the headlight arranged. This back reflector 6 assigns one the optical axis 5 of the main reflector 2 is essentially centrally symmetrical Light passage opening 8 so that a portion of the light from the light source near the axis 1 emerges freely from the headlight through the rear reflector. Only the share of Light emitted from the light source at an angle greater than one is a predetermined reference angle, is reflected by the back reflector 6.

Zur Verdeutlichung der Wirkung des erfindungsgemäßen Rückreflektors 6 sind in Fig. 1 zwei Strahlen 11 und 12 dargestellt, wobei der Strahl 12 so gewählt wurde, dass er durch den Rückreflektor 6 beeinflusst wird, während als anderer Strahl 11 ein unbeeinflusst bleibender Strahl gewählt wurde. Der erfindungsgemäße Rückreflektor 6 ist vorzugsweise über Halterungselemente 7 an dem Leuchtenmodul in Höhe des (optionalen) optischen Elements 9 befestigt. Der unbeeinflusste Strahl 11 tritt aus der Lichtquelle 1 aus, erreicht die Lichtdurchtrittsöffnung 8 des Rückreflektors und das optische Element 9 darin, das zur Strahlformung dient. Er wird dort (wie im Stand der Technik) durch das optische Element 9 in einer gewünschten Richtung abgelenkt. Der Winkel zwischen dem Strahl 11 und der optischen Achse 5 überschreitet dabei nirgends einen vorgegebenen Wert.To clarify the effect of the back reflector 6 according to the invention, there are two in FIG. 1 Rays 11 and 12 are shown, the beam 12 being selected so that it is characterized by the Back reflector 6 is influenced, while as another beam 11 an unaffected Beam was chosen. The back reflector 6 according to the invention is preferably over Bracket elements 7 on the lamp module in the amount of the (optional) optical element 9 attached. The uninfluenced beam 11 emerges from the light source 1, reaches the Light passage opening 8 of the rear reflector and the optical element 9 therein, which for Beam shaping is used. It is there (as in the prior art) by the optical element 9 in distracted from a desired direction. The angle between the beam 11 and the optical axis 5 never exceeds a predetermined value.

Der Strahl 12 verlässt die Lichtquelle 1 unter einem Winkel, der größer als der vorgegebene Wert ist: der Strahl 12 ist im Gegensatz zu Strahl 11 kein achsennaher Strahl. Der Strahl 12 trifft daher auf den erfindungsgemäßen Rückreflektor 6, von dem er "zurückgeworfen" wird, d.h. durch den er an einem direkten Austritt durch die Lichtscheibe 3 aus dem Scheinwerfer gehindert wird. Nachdem der Strahl 12 durch den Rückreflektor 6 zurückgeworfen wurde, erreicht er seitlich versetzt den Außenabschnitt 10 des Hauptreflektors 2. Dort wird seine Richtung ein weiteres Mal geändert, so dass er nun an dem Rückreflektor vorbei durch die Lichtscheibe 3 den Scheinwerfer verlässt. The beam 12 leaves the light source 1 at an angle that is greater than the predetermined one The value is: in contrast to beam 11, beam 12 is not a beam close to the axis. The ray 12 therefore strikes the back reflector 6 according to the invention, from which it is "thrown back", i.e. through which he at a direct exit through the lens 3 from the headlight is prevented. After the beam 12 is reflected by the back reflector 6, it reaches the outer section 10 of the main reflector 2 offset laterally Direction changed one more time so that it now passes the back reflector through the Lens 3 leaves the headlight.

Der Anteil des ungehindert durch die Lichtdurchtrittsöffnung (mit optischem Element 9) tretenden Lichtes bzw. des durch den Rückreflektor 6 zurückgeworfenen Lichtes wird durch den Raumwinkel bestimmt, der durch die Form der Lichtdurchtrittsöffnung 8 in dem Rückreflektor 9 definiert wird. Fig. 2 zeigt eine sehr einfache Form des Rückreflektors 6 mit Lichtdurchtrittsöffnung 8 in Draufsicht, d.h. gesehen in Richtung der optischen Achse. In der gezeigten Ausführungsform des Rückreflektors 6 ist dieser und die darin enthaltene Lichtdurchtrittsöffnung kreisförmig. Damit ergibt sich als Raumwinkel ein Wert, der proportional zu dem Quadrat des Verhältnisses von Radius der Lichtdurchtrittsöffnung 8 und Abstand zwischen Lichtquelle 1 und Rückreflektor 6 ist. Die Wahl der Form der Lichtdurchtrittsöffnung 8 des Rückreflektors 6 hängt aber wesentlich von den Anforderungen in Bezug auf das Design des Scheinwerfers ab. Daher wird die Lichtdurchtrittsöffnung 8 im Allgemeinen eher eine elliptische, rechteckige oder quadratische Form haben und damit einen anderen Raumwinkel ergeben.The proportion of the unhindered through the light passage opening (with optical element 9) emerging light or the light reflected by the back reflector 6 is through the solid angle determined by the shape of the light passage opening 8 in the Back reflector 9 is defined. Fig. 2 shows a very simple shape of the rear reflector 6 with Light passage opening 8 in plan view, i.e. seen in the direction of the optical axis. In the shown embodiment of the rear reflector 6 is this and the contained therein Circular light opening. This results in a value as the solid angle that proportional to the square of the ratio of the radius of the light passage opening 8 and Distance between light source 1 and back reflector 6 is. The choice of the shape of the Light passage opening 8 of the rear reflector 6 depends essentially on the requirements in terms of the design of the headlamp. Therefore, the light passage opening 8 in Generally more of an elliptical, rectangular or square shape and thus result in a different solid angle.

Darüber hinaus kann der Rückreflektor 6 in Bezug auf die optische Achse 5 des Hauptreflektors 2 schräg gestellt sein, so dass er "parallel" zu dem Verlauf der Lichtscheibe 3 steht. So kann der Rückreflektor beim rechten Scheinwerfer des Fahrzeugs beispielsweise in Bezug auf das Fahrzeug von außen nach innen schräg nach vorne verlaufen. Die Stellung des Rückreflektors 6 ist dabei selbstverständlich maßgeblich für die oben genannte effektive Fläche der Lichtdurchtrittsöffnung 8 und damit für den effektiven Raumwinkel des Rückreflektors 6.In addition, the back reflector 6 with respect to the optical axis 5 of the Main reflector 2 be inclined so that it is "parallel" to the course of the lens 3 stands. For example, the rear reflector in the right headlight of the vehicle can be in With respect to the vehicle, run diagonally forward from the outside. The position of the rear reflector 6 is of course decisive for the above-mentioned effective Area of the light passage opening 8 and thus for the effective solid angle of the Rear reflector 6.

In Fig. 1 weist der Rückreflektor 6 eine konvexe Reflektorfläche auf, wenn man den Rückreflektor 6 von der Lichtquelle 1 aus betrachtet. Dies hat den oben mit Bezug auf den Strahl 12 beschriebenen Strahlengang zur Folge. In einer anderen, nicht dargestellten bevorzugten Ausführungsform der Erfindung weist der Rückreflektor 6 dagegen eine konkave Reflektorfläche auf. Die beiden unterschiedlichen Formen der Reflektorfläche bewirken unterschiedliche Muster im Strahlkegel des Scheinwerfers mit dem erfindungsgemäßen Rückreflektor 6. Während bei der konvexen Reflektorfläche das von der Lichtquelle kommende Licht durch den Rückreflektor 6 weiter zerstreut wird, wird es bei der konkaven Reflektorfläche ringförmig gebündelt. Beim konvexen Rückreflektor 6 erhält man so eine in etwa stufenlose, gleichförmige Abnahme der Lichtintensität von der optischen Achse nach außen im Lichtkegel. Dagegen führt die konkave Reflektorfläche zu einer Abstufung in der Intensitätsverteilung des Scheinwerfers, es ergibt sich eine ringförmig abgestufte Intensitätsverteilung im Strahlkegel. In beiden Fällen ist die Abstrahlcharakteristik des Scheinwerfers nicht mehr so "grell" und das Erscheinungsbild des erfindungsgemäßen Projektionsscheinwerfers "weicher" im Vergleich zu Scheinwerfern nach dem Stand der Technik.In Fig. 1, the back reflector 6 has a convex reflector surface when the Back reflector 6 viewed from the light source 1. This has the same with respect to the Beam 12 result in the described beam path. In another, not shown preferred embodiment of the invention, however, the back reflector 6 has a concave reflector surface. The two different forms of the reflector surface cause different patterns in the beam cone of the headlight with the back reflector according to the invention 6. While the convex reflector surface of the Light source coming light is further dispersed by the back reflector 6, it will at concave reflector surface bundled in a ring. With the convex back reflector 6 one obtains such an approximately stepless, uniform decrease in light intensity from the optical one Axis outwards in the light cone. In contrast, the concave reflector surface leads to a Gradation in the intensity distribution of the headlight, there is a ring graduated intensity distribution in the beam cone. The radiation pattern is in both cases the headlight is no longer so "bright" and the appearance of the invention Projection headlights "softer" compared to headlights according to the state of the Technology.

Die Breite des Rückreflektors 6 ist vorzugsweise so gewählt, dass bei Draufsicht auf den Scheinwerfer in den Scheinwerfer die eingebaute Halterungselemente 7 z.B. für das optische Element 9 bzw. für den Rückreflektor 6 durch den Rückreflektor 6 verdeckt werden und so ein homogeneres Erscheinungsbild des Scheinwerfers erzielt wird. The width of the back reflector 6 is preferably chosen so that when looking at the Headlights in the headlights the built-in mounting elements 7 e.g. for the optical Element 9 or for the back reflector 6 are covered by the back reflector 6 and so a more homogeneous appearance of the headlamp is achieved.
