Aufgabe der vorliegenden Erfindung ist es, einen Scheinwerfer für Fahrzeuge derart weiterzubilden, so das Platz sparend Bereiche des Verkehrsraumes erfasst werden, die sich von den durch die üblichen Lichtfunktionen erfassten Bereichen des Verkehrsraums unterscheiden.task The present invention is a headlamp for vehicles so educate, so the space-saving areas of the traffic area which are different from those covered by the usual lighting functions Areas of the traffic area.
Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass dem Abstrahlelement ein verschwenkbares Spiegelelement zur Bestrahlung und/oder Detektion des Verkehrsraumes entlang einer horizontalen und/oder vertikalen Vorzugsrichtung zugeordnet ist einerseits und dass eine in entlang einer vorgegebenen Richtung versetzt zueinander verlaufenden Teilbereichen angeordnete Teilmenge von Abstrahlelementen und/oder Detektierelementen zu- und abschaltbar ist zur Bestrahlung und/oder Detektion des Verkehrsraumes entlang einer vertikalen und/oder horizontalen Vorzugsrichtung andererseits.to solution This object is the invention in conjunction with the preamble of the patent claim 1, characterized in that the radiating element a pivotable mirror element for irradiation and / or detection the traffic space along a horizontal and / or vertical Preferred direction is assigned on the one hand and that in along a predetermined direction offset from each other extending portions arranged subset of radiating elements and / or detection elements can be switched on and off for the irradiation and / or detection of the traffic area along a vertical and / or horizontal preferred direction on the other.
Der besondere Vorteil der Erfindung besteht darin, dass eine gezielte Erfassung eines definierten Bereiches des Verkehrsraums ermöglicht wird, der sich von dem ansonsten üblichen, durch die herkömmlichen Lichtfunktionen vorgegebenen Bereich des Verkehrsraums unterscheidet. Die Erfassung eines räumlich fest umgrenzten Bereiches des Verkehrsraums wird zum einen durch einen rotierbaren/verschwenkbaren Spiegel ermöglicht, der die von mindestens einem Abstrahlelement abgegebene Abstrahlung in einer horizontalen und/oder vertikalen Vorzugsrichtung umlenkt. Zum anderen ermöglicht das Zu- und Abschalten von Teilmengen der Abstrahlelemente bzw. der Detektierelemente eine weitere Möglichkeit, eine Bestrahlung bzw. Detektion des Verkehrsraumes entlang einer vertikalen und/oder horizontalen Vorzugsrichtung zu verwirklichen. Vorzugsweise ist der Spiegel in einer horizontalen Ebene verschwenkbar gelagert, so dass er eine Bestrahlungsverteilung in einer horizontalen Vorzugsrichtung ermöglicht. Durch Kombination mit der Zu- und Abschaltung von Teilbereichen der Abstrahlelemente bzw. Detektierelemente, die sich bei der Abstrahlverteilung hinsichtlich der vertikalen Vorzugsrichtung auswirken, kann Platz sparend ein „Markierungslicht-Scheinwerfer" erzeugt werden, der zusätzlich zu einem herkömmlichen Scheinwerfer Einsatz findet.Of the particular advantage of the invention is that a targeted Capturing a defined area of the traffic area, different from the usual, through the conventional Light functions predetermined area of the traffic area is different. The capture of a spatial firmly bounded area of the traffic area is on the one hand through allows a rotatable / pivotable mirror that of at least a radiating element emitted radiation in a horizontal and / or vertical preferred direction deflects. On the other hand that allows Switching on and off of subsets of the radiating elements or the Detection elements another way an irradiation or detection of the traffic space along a vertical and / or horizontal preferred direction. Preferably, the mirror is pivotable in a horizontal plane stored so that it has an irradiation distribution in a horizontal Preferred direction allows. By combination with the connection and disconnection of partial areas the radiating elements or detection elements, which are in the distribution of radiation Concerning the vertical preferential direction, space can saving a "marker light headlight" are generated, the additional to a conventional one Headlight insert finds.
Nach einer bevorzugten Ausführungsform der Erfindung besteht das Feld von Abstrahlelementen zum einen aus einer Mehrzahl von Licht emittierenden Abstrahlelementen und/oder einer Mehrzahl von nicht Licht emittierenden Detektierelementen und/oder mindestens einem nicht Licht emittierenden Abstrahlelement. Die Licht emittierenden Abstrahlelemente können beispielsweise als weißes Licht emittierende Hochleistungs-Leuchtdioden (LED) oder als Halbleiterleuchtelemente (LED-Chips) ausgebildet sein. Das nicht Licht emittierende Abstrahlelement kann als eine im Infrarot-Bereich abstrahlende Laserdiode ausgebildet sein, deren Strahlung von den als Fotodioden ausgebildeten Detektierelementen erfasst wird, damit die ermittelten Detektiersignale zur visuellen Überlagerung eines virtuellen Bildes in einem Head-up-Display einer Anzeigevorrichtung (Windschutzscheibe) des Fahrzeugs dargestellt werden können. Der Spiegel hat hierbei eine Doppelfunktion. Er kann zum einen vorzugsweise zur Beleuchtung des Verkehrsraums in horizontaler Richtung und zum anderen zur Detektion eines Bereiches des Verkehrsraums im nicht sichtbaren Bereich eingesetzt werden.According to a preferred embodiment of the invention, the array of emission elements consists of a plurality of light-emitting emission elements and / or a plurality of non-light-emitting detection elements and / or at least one non-light-emitting emission element. The light-emitting radiation Elements can be designed, for example, as high-performance light-emitting diodes (LED) emitting white light or as semiconductor light-emitting elements (LED chips). The non-light-emitting radiating element can be embodied as a laser diode radiating in the infrared range, the radiation of which is detected by the detection elements embodied as photodiodes, so that the detected detection signals for visually superposing a virtual image in a head-up display of a display device (windshield) of the vehicle can be displayed. The mirror has a double function here. On the one hand, it can preferably be used for illuminating the traffic space in the horizontal direction and, on the other hand, for detecting an area of the traffic space in the non-visible area.
Nach einer Weiterbildung der Erfindung sind die Licht emittierenden Abstrahlelemente als Leuchtdioden-Chips ausgebildet, deren Anzahl in einem LED-Feld (LED-Array) klein gehalten werden kann, da sie im Zusammenwirken mit dem drehenden Spiegel eine relativ breite Ausleuchtung (in horizontaler Richtung) ermöglichen.To In a further development of the invention, the light emitting radiating elements designed as light-emitting diode chips whose number in an LED field (LED array) can be kept small, as they interact with the rotating mirror a relatively wide illumination (in horizontal direction) enable.
Nach einer Weiterbildung der Erfindung ist eine Ansteuereinheit vorgesehen, mittels derer die Verdrehgeschwindigkeit bzw. der Verschwenkwinkelbereich des Spiegels festlegbar ist.To a development of the invention, a drive unit is provided, by means of which the rotational speed or Verschwenkwinkelbereich of the mirror can be fixed.
Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further Advantages of the invention will become apparent from the other dependent claims.

In Verbindung mit mindestens einem ortsfern angeordneten Radarsensor und/oder mindestens einem Ultraschallsensor und/oder wenigstens einem LIDAR-Abstandssensor können in Verbindung mit einem auswählenden und steuernden Mikrocomputer gezielt Objekte im Verkehrsraum detektiert und ausgeleuchtet werden. Der erfassbare Bereich geht über den durch die übliche Lichtfunktion des Abblendlichtes erfassten Bereich hinaus und bewirkt somit eine Erhöhung der Verkehrssicherheit.In Connection with at least one remote radar sensor and / or at least one ultrasonic sensor and / or at least a LIDAR distance sensor can in conjunction with a selective one and controlling microcomputer targeted objects detected in traffic and be lit up. The detectable range goes over the by the usual Light function of the low beam detected area and causes thus an increase traffic safety.
