Description
Die Erfindung betrifft eine Leuchte für Verkehrseinrichtungen mit einer Lichtquelle, der zum Erzeugen eines Lichtstrahls in Strahlrichtung eine Linsenoptik nachgeordnet ist.The invention relates to a luminaire for traffic facilities with a light source, which is arranged downstream of a lens optics for generating a light beam in the beam direction.
Derartige Leuchten für Verkehrseinrichtungen sind beispielsweise Signallampen für Schienenfahrzeuge oder Ampelleuchten oder Scheinwerfer für Straßenfahrzeuge.Such lights for traffic facilities are, for example, signal lamps for rail vehicles or traffic lights or headlights for road vehicles.
Die Linsenoptik bewirkt, daß die Leuchte eine sehr hohe Lichtstärke aufweist. Bei Signallampen für Schienenfahrzeuge ist die Lichtstärke beispielsweise so groß, daß die Leuchte noch in etwa 3 km Entfernung vom ankommenden Zugführer gesehen werden kann.The lens optics causes the lamp has a very high light intensity. For signal lamps for rail vehicles, the light intensity is for example so large that the lamp can still be seen in about 3 km away from the arriving train driver.
Üblicherweise wird die Linsenoptik von einer Sammellinse gebildet, in deren Brennpunkt sich eine Glühlampe befindet. Hohe Lichtstärken lassen sich insbesondere dann erzielen, wenn die Glühwendel der Glühlampe exakt in den Brennpunkt der Sammellinse einjustiert ist. Das Einjustieren der Glühwendel in den Brennpunkte der Sammellinse ist jedoch sehr aufwendig und erfolgt im allgemeinen manuell über eine mechanische Stellvorrichtung.Usually, the lens optics is formed by a converging lens, in the focal point of which is a light bulb. High light intensities can be achieved, in particular, when the incandescent filament of the incandescent lamp is precisely adjusted into the focal point of the condenser lens. However, the Einjustieren the filament in the focal points of the converging lens is very expensive and is generally done manually via a mechanical actuator.
Die Druckschrift
Ferner ist bekannt, die Strahlrichtung von Autoscheinwerfern, beispielsweise durch Verkippen der Linsenoptik, an die jeweilige Verkehrssituation anzupassen.It is also known to adapt the beam direction of car headlights, for example by tilting the lens optics, to the respective traffic situation.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Leuchte für Verkehrseinrichtungen anzugeben, die eine besonders geringe Größe aufweist sowie besonders einfach und wirtschaftlich hergestellt werden kann.Based on this prior art, the present invention seeks to provide a lamp for traffic facilities, which has a particularly small size and can be made particularly simple and economical.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Lichtquelle ein von einzelnen Lumineszenzdiodenchips gebildetes Lumineszenzdiodenfeld umfaßt, deren Lumineszenzdioden von einer Auswahlrichtung gesteuert einen Leuchtbereich bilden, durch dessen Ort und Ausdehnung die Richtung und Strahldivergenz des Lichtstrahls einstellbar ist.This object is achieved in that the light source comprises a formed by individual LED chips Lumineszenzdiodenfeld whose light-emitting diodes controlled by a selection direction form a luminous area, by its location and extent the direction and beam divergence of the light beam is adjustable.
Bei der Leuchte gemäß der Erfindung ist die Richtung und die Strahldivergenz des Lichtstrahls auf einfache Weise durch den Ort und die Größe des Leuchtbereichs einstellbar. Der Ort und die Größe des Leuchtbereichs auf dem Lumineszenzdiodenfeld läßt sich seinerseits durch Ansteuern der Lumineszenzdioden des Lumineszenzdiodenfelds festlegen. Bei der Leuchte gemäß der Erfindung sind daher keine mechanischen Stellvorrichtungen für die Einstellung der Richtung und der Strahldivergenz des Lichtstrahls nötig. Die Richtung und Strahldivergenz ist somit auf einfache Weise durch Auswahl der Lumineszenzdioden möglich.In the luminaire according to the invention, the direction and the beam divergence of the light beam are easily adjustable by the location and the size of the luminous area. The location and size of the luminous area on the light-emitting diode array can in turn be determined by driving the light-emitting diodes of the light-emitting diode array. In the luminaire according to the invention therefore no mechanical adjusting devices for the adjustment of the direction and the beam divergence of the light beam are necessary. The direction and beam divergence is thus possible in a simple manner by selecting the light-emitting diodes.
