Aufgabe der vorliegenden Erfindung ist es daher, einen Scheinwerfer für Kraftfahrzeuge derart weiterzubilden, dass ein hoher Ausleuchtungsgrad des Kraftfahrzeugvorfeldes ermöglicht wird, ohne dass eine Blendung weiterer Verkehrsteilnehmer, insbesondere entgegenkommender Verkehrsteilnehmer, gewährleistet ist.task The present invention is therefore a headlamp for Developing motor vehicles such that a high degree of illumination of the Motor vehicle apron is made possible without a Dazzling other road users, especially oncoming Road users, is guaranteed.
Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass die Lichtquelleneinrichtung eine Ansteuereinheit und ein Feld von LED-Lichtquellen aufweist, wobei die Ansteuereinheit zur Ansteuerung der LED-Lichtquellen ein Pulssignal erzeugt, mittels dessen in einer Impulsdauer des Pulssignals Licht abstrahlbar ist, dass die Lichtsensoreinrichtung mindestens einen Sensor mit einem Feld von Sensorelementen aufweist, mittels dessen in einer Pausendauer des Pulssignals die Helligkeit des Vorfeldes detektierbar ist, dass den Feldern jeweils eine Optikeinheit vorgelagert ist, derart, dass ein Paar von LED-Lichtquellen und Sensorelementen denselben Bereich des Vorfeldes zugeordnet sind, dass die Ansteuereinheit Mittel aufweist, dass der Scheinwerfer aus einer Fernlichtstellung, in der alle LED-Lichtquellen eingeschaltet sind zur Erzeugung einer Fernlichtverteilung, in Abhängigkeit von dem Ansprechen des mindestens einen Sensorelementes während der Pausendauer des Pulssignals in eine Endblendstellung bringbar ist, in der die zu dem ansprechenden Sensorelement korrespondierende LED-Lichtquelle ausgeschaltet oder heruntergedimmt ist zur Bildung eines eindeutig begrenzten Endblendbereiches in der Lichtverteilung, wobei sich in dem Endblendbereich das Verkehrsobjekt befindet.to Solution to this problem is the invention in connection with the preamble of claim 1, characterized in that the light source device comprises a drive unit and a field of Has LED light sources, wherein the drive unit for driving the LED light sources generates a pulse signal by means of which in one Pulse duration of the pulse signal light is emitted, that the light sensor device has at least one sensor with a field of sensor elements, by means of which, in a pause duration of the pulse signal, the brightness of the apron is detectable that the fields each have an optical unit is upstream, such that a pair of LED light sources and Sensor elements are assigned to the same area of the apron, in that the drive unit has means that the headlight from a high beam position in which all the LED light sources are turned on are for generating a high beam distribution, depending on the response of the at least one sensor element during the pause duration of the pulse signal can be brought into an end aperture position is, in which the corresponding to the responsive sensor element LED light source is off or dimmed to formation a clearly limited end-blend area in the light distribution, wherein in the Endblendbereich the traffic object is located.
Nach der Erfindung wirkt eine Ansteuereinheit der Lichtquelleneinrichtung auf die LED-Lichtquellen derart mit einem Pulssignal ein, dass ein solcher gepulster Lichtstrahl erzeugt wird, dass zum einen ein für die vorgegebene Lichtverteilung erforderlicher Lichtstrom erzeugt wird und zum anderen eine Dunkelphase des Lichtstromsignals dazu genutzt wird, die Helligkeit des Fahrzeugvorfeldes zu erfassen. LED-Lichtquellen der Lichtquelleneinrichtung sind in einem Feld zusammengefasst, Sen sorelemente der Lichtsensoreinrichtung sind in einem Feld zusammengefasst. Ein Teilbereich des Vorfeldes wird von einem Paar von einer LED-Lichtquelle und einem Sensorelement bestrahlt bzw. erfasst. Erfindungsgemäß ist eine feste paarweise Zuordnung zwischen LED-Lichtquellen einerseits und Sensorelemente andererseits vorgesehen, so dass bei Erkennen eines Vorhandenseins bzw. Ort eines Verkehrsobjektes im Kraftfahrzeugvorfeld der Scheinwerfer direkt aus einer Fernlichtstellung in eine Endblendstellung überführbar ist, in der lediglich der Teil des Vorfeldes, in dem sich das weitere Verkehrsobjekt befindet, von der Ausleuchtung ausgespart wird. Vorteilhaft kann somit verkehrssituationsabhängig eine umfassende Ausleuchtung des Kraftfahrzeugvorfeldes und eine dynamische Ausblendung bzw. Entblendung eines Bereiches erfolgen, in dem sich ein weiteres Verkehrsobjekt befindet. Vorteilhaft ist eine direkte optische und elektrische Zuordnung zwischen zueinander korrespondierenden LED-Lichtquellen und Sensorelementen geschaffen, so dass die Fehleranfälligkeit des Scheinwerfers relativ gering ist. Insbesondere können Schaltfehler, Algorithmenfehler und Justagefehler reduziert bzw. vermieden werden.According to the invention, a drive unit of the light source device acts on the LED light sources with a pulse signal such that a pulsed light beam is generated, on the one hand generating a luminous flux required for the given light distribution and, on the other hand, using a dark phase of the luminous flux signal, to detect the brightness of the vehicle apron. LED light sources of the light source device are combined in one field, Sen sorelemente the light sensor device are combined in one field. A portion of the apron is irradiated by a pair of an LED light source and a sensor element. According to the invention, a fixed pairwise association between LED light sources on the one hand and sensor elements on the other hand is provided, so that upon detection of a presence or location of a traffic object in the motor vehicle apron, the headlight can be transferred directly from a high beam position into an end blind position in which only the part of the apron, in the further traffic object is located, is omitted by the illumination. Advantageously, depending on the traffic situation, a comprehensive illumination of the motor vehicle apron and a dynamic suppression or glare suppression of an area in which another traffic object is located can thus take place. Advantageously, a direct optical and electrical association between mutually corresponding LED light sources and sensor elements is created, so that the error rate of the headlamp is relatively low. In particular, switching errors, algorithm errors and adjustment errors can be reduced or avoided to become.
Nach einer Ausführungsform der Erfindung sind die LED-Lichtquellen bzw. Sensorelemente mit der gleichen Rasterung in dem Feld angeordnet, so dass über gleiche oder dieselbe vorgelagerte Optikeinheit eine einfache „Paarbildung” von LED-Lichtquellen und Sensorelementen ermöglicht wird.To an embodiment of the invention are the LED light sources or sensor elements with the same screening arranged in the field, so that about the same or the same upstream optical unit a simple "pairing" of LED light sources and sensor elements is enabled.
Nach einer bevorzugten Ausführungsform der Erfindung ist eine Ansteuereinheit vorgesehen, derart, dass ein Pulssignal zur Ansteuerung der LED-Lichtquellen mit über ein vorgegebenes Zeitintervall veränderlichen Parametern erzeugt wird. Vorzugsweise sind die Parameter des Pulssignals derart veränderlich eingestellt, dass die Dunkelphasen der gepulsten Lichtstrahlen nicht phasengleich mit Dunkelphasen gepulster Lichtstrahlen eines anderen, entgegenkommenden Kraftfahrzeugs sind. Hierdurch wird vermieden, dass aufgrund der Phasengleichheit der Pausendauern der Lichtsignale des einen Kraftfahrzeugs und des anderen Kraftfahrzeugs das Vorhandensein bzw. Ort des anderen Kraftfahrzeugs nicht erkannt bzw. erfasst würde. Ein entgegenkommendes Fahrzeug, das mit dem gleichen Scheinwerfer ausgerüstet wird, wird somit in jedem Fall erkannt.To a preferred embodiment of the invention is a Actuator provided such that a pulse signal for driving the LED light sources with over a predetermined time interval variable parameters is generated. Preferably set the parameters of the pulse signal so variable, that the dark phases of the pulsed light rays are not in phase with dark phases of pulsed light rays of another, oncoming Motor vehicle are. This avoids that due to the Phase equality of the pause durations of the light signals of a motor vehicle and the other motor vehicle the presence or location of the other Motor vehicle not recognized or detected. An accommodating one Vehicle equipped with the same headlight is thus recognized in each case.
Nach einer Weiterbildung der Erfindung weist die Ansteuereinheit einen Zufallsgenerator auf, so dass die LED-Lichtquellen mit einem zufallsbasierten Pulssignal beaufschlagt werden. Auf diese Weise wird mit hoher Wahrscheinlichkeit ein entgegenkommendes Fahrzeug bei eingeschaltetem Scheinwerfer erkannt, so dass der Scheinwerfer aus der Fernlichtstellung in eine Entblendstellung bringbar ist, in der in Abhängigkeit von dem Ort des entgegenkommenden Fahrzeugs eine Entblendung des Gegenverkehrs vorgenommen wird, wobei lediglich der Teil des Vorfeldes nicht ausgeleuchtet wird, in dem sich das entgegenkommende Fahrzeug aktuell befindet.To a development of the invention, the drive unit a Random generator on, so that the LED light sources with a random-based Pulse signal are applied. This way will be highly likely an oncoming vehicle with the headlamp on detected so that the headlight from the high beam position in a Entblendstellung can be brought, in depending on the location of the oncoming vehicle a glare of oncoming traffic is made, with only the part of the apron is not illuminated becomes, in which the oncoming vehicle is currently located.
Nach einer Weiterbildung der Erfindung wird eine zufällige Impulsfolge oder eine festgelegte Pulsfolge periodisch wiederholt, wobei der mittlere Lichtstrom während der Periode konstant ist. Vorteilhaft kann hierdurch eine Lichtabstrahlung einer Bildung einer konstanten mittleren Lichtintensität geschaffen werden einerseits und das Erkennen eines entgegenkommenden Fahrzeugs sicher erfasst werden andererseits.To a development of the invention is a random pulse train or a fixed pulse sequence is repeated periodically, the mean luminous flux is constant during the period. Advantageously thereby a light emission of a formation of a constant middle Light intensity to be created on the one hand and the recognition On the other hand, an oncoming vehicle can be safely detected.
Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further Advantages of the invention will become apparent from the other dependent claims.
