DieErfindung betrifft einen Scheinwerfer für ein Fahrzeug mit einer Tagfahrlichtanordnung,insbesondere unter Verwendung des Reflektors für das Fernlicht oder für das Nebellicht.TheThe 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.
EinTagfahrlicht hat die Erkennbarkeit des Fahrzeugs durch andere Verkehrsteilnehmerim Fahrbetrieb zum Ziel, ohne diese zu blenden. Das Tagfahrlichtist nicht zum Ausleuchten der Fahrbahn bestimmt, sondern vielmehrdazu, von anderen Verkehrsteilnehmern besser erkannt zu werden.Grundsätzlichkann das normale Abblendlicht als Tagfahrlicht verwendet werden.OneDaytime running lights have the recognizability of the vehicle by other road userswhile driving to the destination, without blinding them. The daytime running lightis not intended to illuminate the road, but ratherto be better recognized by other road users.in principlethe normal dipped beam can be used as daytime running lights.

Esist Aufgabe der Erfindung, einen Scheinwerfer für ein Fahrzeug mit einer Tagfahrlichtanordnungnach dem Oberbegriff des Anspruchs 1 alternativ so zu gestalten,dass das Tagfahrlicht mit einer für das Fahrlicht eingesetztenLichtquelle gebildet wird.ItObject of the invention is a headlight for a vehicle with a daytime running light arrangementalternatively according to the preamble of claim 1,that the daytime running light with a used for the driving lightLight source is formed.
DieseAufgabe wird bei einem Scheinwerfer nach dem Oberbegriff des Anspruchs1 durch dessen kennzeichnende Merkmale gelöst. Vorteilhafte Ausgestaltungensind in den Unteransprüchenaufgeführt.TheseTask is in a headlight according to the preamble of the claim1 solved by its characterizing features. Advantageous embodimentsare in the subclaimslisted.
DieErfindung besteht darin, dass bei einem Scheinwerfer, der einenReflektor fürein Abblendlicht, ein Fernlicht oder ein Nebellicht als Fahrlicht undeine Lichtquelle aufweist, der Reflektor auf der optischen Achserelativ zur Lichtquelle verschiebbar angeordnet ist, wobei der Brennpunktdes Reflektors zur Bildung des Fahrlichtes mit der Lichtquelle übereinstimmtund zur Bildung eines Tagfahrlichtes aus der Lichtquelle herausverschoben ist. Zu dieser Defokusierung kann entweder die Lichtquelle,oder es kann der Reflektor verschiebbar angeordnet sein. Durch dieseRelativverschiebung vom Reflektor gegenüber der Lichtquelle wird letztereauf dem Reflektor unscharf abgebildet, es werden die fotometrische Lichtverteilungdesselben geändertund die Lichtstärkereduziert. Es wird ein blendfreies, insbesondere diffuses und wenigerstarkes Licht abgestrahlt. Der Vorteil liegt darin, dass bei diesemScheinwerfer mit der gleichen Lichtquelle zwei Lichtfunktionen erfüllt werden.Ein separates Gehäusemit einer Beleuchtungseinrichtung für das Tagfahrlicht wird nichtbenötigt.Der fürden Scheinwerfer im Fahrzeug vorgesehene Bauraum wird somit optimalgenutzt.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.
Dabeiist vorteilhaft der Reflektor verschiebbar angeordnet, und zwarzwischen der Position, in der dessen Brennpunkt mit der Lichtquelle übereinstimmt,und einer vorbestimmten Position auf der optischen Achse, in derdessen Brennpunkt im Abstand von der Lichtquelle auf der der Lichtaustrittseiteabgewandten Seite des Scheinwerfers liegt. Zur Verschiebung istder Reflektor auf einfache Weise mit einem Stellantrieb gekoppelt.thereis advantageously arranged the reflector displaceable, namelybetween the position where its focal point coincides with the light source,and a predetermined position on the optical axis in whichits focal point at a distance from the light source on the light exit sidefacing away from the headlamp. To the shift isthe reflector coupled in a simple manner with an actuator.
ZurVerbesserung der optischen Anmutung des Tagfahrlichtes kann demReflektor lichtabstrahl- undumfangsseitig ein zweiter Reflektor zugeordnet sein, der ortsfestgegenüberder optischen Achse und damit scheinwerferfest angeordnet ist unddessen Brennpunkt mit der Lichtquelle übereinstimmt. Dieser Reflektorkann ringförmigausgebildet sein. Im Falle einer solchen Ausbildung wird das lichtstärkereduzierte,diffuse Tagfahrlicht von einem deutlich erkennbaren Ring umgeben.toImproving the visual appearance of the daytime running lights can theReflector light emission andbe assigned circumferentially a second reflector, the stationaryacross fromthe optical axis and thus headlight fixed and is arrangedwhose focal point coincides with the light source. This reflectorcan be ring shapedbe educated. In the case of such a training, the light intensity is reduced,diffused daytime running lights surrounded by a clearly recognizable ring.
DieAnordnung des zweiten Reflektors ist dabei so getroffen, dass dieserden ersten Reflektor in dessen Tagfahrlichtposition umgibt und damitergänzt,wobei sein Innendurchmesser größer alsder Außendurchmesserdes ersten, verschiebbar angeordneten Reflektors ist, jedoch imwesentlichen diesem entspricht. In dieser Position, in der der Brennpunktdes ersten Reflektors außerhalbder Lichtquelle liegt, strahlt dieser, wie oben beschrieben, diffuses Lichtaus, das die Anforderung an ein Fahrlicht nicht erfüllt. Dasvon dem ringförmigenzweiten Reflektor in dieser Anordnung ausgestrahlte diffuse Lichtist dabei wegen seiner Charakteristik deutlicher wahrnehmbar undumschließtdas vom ersten Reflektor abgestrahlte Licht als heller Ring. Damitwerden auf einfache Weise zwei Anforderungen an das Tagfahrlichterfüllt,nämlichdie Forderung nach einer Mindestabstrahlfläche für dieses und die Forderungnach einem Erregen der Aufmerksamkeit des entgegenkommenden Verkehrs,ohne diesen zu blenden. In der Fahrlichtposition, in der der Brennpunktdes ersten Reflektors in der Lichtquelle liegt, treffen keine vonder Lichtquelle ausgestrahlten Lichtstrahlen auf den zweiten Reflektor,da dieser im Schatten des ersten liegt. Es wird ausschließlich Lichtvon dem ersten Reflektor ausgesendet, und dieses bildet das Fahrlicht.TheArrangement of the second reflector is made such that thissurrounds the first reflector in the daytime running light position and thusadded,wherein its inner diameter is greater thanthe outside diameterthe first, slidably arranged reflector is, however, in theessentially corresponds to this. In this position, where the focusthe first reflector outsidethe light source, this radiates, as described above, diffused lightthat does not meet the requirement for a driving light. Thefrom the annularsecond reflector in this arrangement emitted diffused lightis more noticeable because of its characteristics andsurroundsthe light emitted by the first reflector as a bright ring. In order tobecome two requirements for the daytime running light in a simple wayFulfills,namelythe requirement for a minimum radiating surface for this and the requirementafter arousing the attention of oncoming traffic,without blinding it. In the driving light position in which the focal pointof the first reflector is in the light source, none ofthe light source emitted light beams to the second reflector,because this is in the shadow of the first. It is only lightemitted from the first reflector, and this forms the driving light.
