Abstract
Description
Die Erfindung betrifft einen Scheinwerfer für ein Fahrzeug mit einer Tagfahrlichtanordnung, insbesondere unter Verwendung des Reflektors für das Fernlicht oder für das Nebellicht.The The invention relates to a headlight for a vehicle with a daytime running light arrangement, in particular using the reflector for the high beam or for the fog light.
Ein Tagfahrlicht hat die Erkennbarkeit des Fahrzeugs durch andere Verkehrsteilnehmer im Fahrbetrieb zum Ziel, ohne diese zu blenden. Das Tagfahrlicht ist nicht zum Ausleuchten der Fahrbahn bestimmt, sondern vielmehr dazu, von anderen Verkehrsteilnehmern besser erkannt zu werden. Grundsätzlich kann das normale Abblendlicht als Tagfahrlicht verwendet werden.One Daytime running lights have the recognizability of the vehicle by other road users while driving to the destination, without blinding them. The daytime running light is not intended to illuminate the road, but rather to be better recognized by other road users. in principle the normal dipped beam can be used as daytime running lights.

Es ist Aufgabe der Erfindung, einen Scheinwerfer für ein Fahrzeug mit einer Tagfahrlichtanordnung nach dem Oberbegriff des Anspruchs 1 alternativ so zu gestalten, dass das Tagfahrlicht mit einer für das Fahrlicht eingesetzten Lichtquelle gebildet wird.It Object of the invention is a headlight for a vehicle with a daytime running light arrangement alternatively according to the preamble of claim 1, that the daytime running light with a used for the driving light Light source is formed.
Diese Aufgabe wird bei einem Scheinwerfer nach dem Oberbegriff des Anspruchs 1 durch dessen kennzeichnende Merkmale gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen aufgeführt.These Task is in a headlight according to the preamble of the claim 1 solved by its characterizing features. Advantageous embodiments are in the subclaims listed.
Die Erfindung besteht darin, dass bei einem Scheinwerfer, der einen Reflektor für ein Abblendlicht, ein Fernlicht oder ein Nebellicht als Fahrlicht und eine Lichtquelle aufweist, der Reflektor auf der optischen Achse relativ zur Lichtquelle verschiebbar angeordnet ist, wobei der Brennpunkt des Reflektors zur Bildung des Fahrlichtes mit der Lichtquelle übereinstimmt und zur Bildung eines Tagfahrlichtes aus der Lichtquelle heraus verschoben ist. Zu dieser Defokusierung kann entweder die Lichtquelle, oder es kann der Reflektor verschiebbar angeordnet sein. Durch diese Relativverschiebung vom Reflektor gegenüber der Lichtquelle wird letztere auf dem Reflektor unscharf abgebildet, es werden die fotometrische Lichtverteilung desselben geändert und die Lichtstärke reduziert. Es wird ein blendfreies, insbesondere diffuses und weniger starkes Licht abgestrahlt. Der Vorteil liegt darin, dass bei diesem Scheinwerfer mit der gleichen Lichtquelle zwei Lichtfunktionen erfüllt werden. Ein separates Gehäuse mit einer Beleuchtungseinrichtung für das Tagfahrlicht wird nicht benötigt. Der für den Scheinwerfer im Fahrzeug vorgesehene Bauraum wird somit optimal genutzt.The invention consists in that in a headlight having a reflector for a low beam, a high beam or a fog light as the driving light and a light source, the reflector is slidably disposed on the optical axis relative to the light source, wherein the focus of the reflector for forming the Driving lights coincides with the light source and is shifted out of the light source to form a daytime running light. This defocusing can be either the light source or the reflector can be arranged to be displaceable. As a result of this relative displacement from the reflector relative to the light source, the latter is imaged in a blurred manner on the reflector, the photometric light distribution of the same is changed and the light intensity is reduced. It is radiated a glare-free, especially diffused and less strong light. The advantage is that this headlamp with the same light source two light functions are met. A separate housing with a lighting device for the daytime running lights is not needed. The vorgese for the headlights in the vehicle hene space is thus used optimally.
Dabei ist vorteilhaft der Reflektor verschiebbar angeordnet, und zwar zwischen der Position, in der dessen Brennpunkt mit der Lichtquelle übereinstimmt, und einer vorbestimmten Position auf der optischen Achse, in der dessen Brennpunkt im Abstand von der Lichtquelle auf der der Lichtaustrittseite abgewandten Seite des Scheinwerfers liegt. Zur Verschiebung ist der Reflektor auf einfache Weise mit einem Stellantrieb gekoppelt.there is advantageously arranged the reflector displaceable, namely between the position where its focal point coincides with the light source, and a predetermined position on the optical axis in which its focal point at a distance from the light source on the light exit side facing away from the headlamp. To the shift is the reflector coupled in a simple manner with an actuator.
Zur Verbesserung der optischen Anmutung des Tagfahrlichtes kann dem Reflektor lichtabstrahl- und umfangsseitig ein zweiter Reflektor zugeordnet sein, der ortsfest gegenüber der optischen Achse und damit scheinwerferfest angeordnet ist und dessen Brennpunkt mit der Lichtquelle übereinstimmt. Dieser Reflektor kann ringförmig ausgebildet sein. Im Falle einer solchen Ausbildung wird das lichtstärkereduzierte, diffuse Tagfahrlicht von einem deutlich erkennbaren Ring umgeben.to Improving the visual appearance of the daytime running lights can the Reflector light emission and be assigned circumferentially a second reflector, the stationary across from the optical axis and thus headlight fixed and is arranged whose focal point coincides with the light source. This reflector can be ring shaped be educated. In the case of such a training, the light intensity is reduced, diffused daytime running lights surrounded by a clearly recognizable ring.
Die Anordnung des zweiten Reflektors ist dabei so getroffen, dass dieser den ersten Reflektor in dessen Tagfahrlichtposition umgibt und damit ergänzt, wobei sein Innendurchmesser größer als der Außendurchmesser des ersten, verschiebbar angeordneten Reflektors ist, jedoch im wesentlichen diesem entspricht. In dieser Position, in der der Brennpunkt des ersten Reflektors außerhalb der Lichtquelle liegt, strahlt dieser, wie oben beschrieben, diffuses Licht aus, das die Anforderung an ein Fahrlicht nicht erfüllt. Das von dem ringförmigen zweiten Reflektor in dieser Anordnung ausgestrahlte diffuse Licht ist dabei wegen seiner Charakteristik deutlicher wahrnehmbar und umschließt das vom ersten Reflektor abgestrahlte Licht als heller Ring. Damit werden auf einfache Weise zwei Anforderungen an das Tagfahrlicht erfüllt, nämlich die Forderung nach einer Mindestabstrahlfläche für dieses und die Forderung nach einem Erregen der Aufmerksamkeit des entgegenkommenden Verkehrs, ohne diesen zu blenden. In der Fahrlichtposition, in der der Brennpunkt des ersten Reflektors in der Lichtquelle liegt, treffen keine von der Lichtquelle ausgestrahlten Lichtstrahlen auf den zweiten Reflektor, da dieser im Schatten des ersten liegt. Es wird ausschließlich Licht von dem ersten Reflektor ausgesendet, und dieses bildet das Fahrlicht.The Arrangement of the second reflector is made such that this surrounds the first reflector in the daytime running light position and thus added, wherein its inner diameter is greater than the outside diameter the first, slidably arranged reflector is, however, in the essentially corresponds to this. In this position, where the focus the first reflector outside the light source, this radiates, as described above, diffused light that does not meet the requirement for a driving light. The from the annular second reflector in this arrangement emitted diffused light is more noticeable because of its characteristics and surrounds the light emitted by the first reflector as a bright ring. In order to become two requirements for the daytime running light in a simple way Fulfills, namely the requirement for a minimum radiating surface for this and the requirement after arousing the attention of oncoming traffic, without blinding it. In the driving light position in which the focal point of the first reflector is in the light source, none of the light source emitted light beams to the second reflector, because this is in the shadow of the first. It is only light emitted from the first reflector, and this forms the driving light.
