Aufgabe der vorliegenden Erfindung ist es, eine Leuchte mit Leuchtdioden als Lichtquelle derart weiterzubilden, dass bei ringförmig angeordneten Leuchtdioden eine verbesserte seitliche Lichtabstrahlung ermöglicht wird.Object of the present invention is to develop a luminaire with light-emitting diodes as a light source such that in annularly arranged light emitting diodes improved lateral light emission is possible.
Zur Lösung dieser Aufgabe weist die Erfindung die Merkmale des Patentanspruchs 1 auf.To solve this problem, the invention has the features of
Der besondere Vorteil der Erfindung besteht darin, dass trotz eines ringförmigen Erscheinungsbildes der Leuchte durch Seitenlichtablenkmittel eine größere seitliche Lichtablenkung ermöglicht wird. Hierbei wird ein ringförmiges oder kreisringausschnittförmiges Teillichtbündel in eine seitliche Vorzugsrichtung abgelenkt, so dass aus seitlichen Blickrichtungen die Leuchtfunktion, vorzugsweise die ringförmige Leuchtfunktion, erkennbar ist. Vorteilhafter Weise kann die Leuchte als Blinklichtleuchte ausgebildet sein, so dass durch die verbesserte seitliche Erkennbarkeit die Sicherheit im Straßenverkehr erhöht werden kann.The particular advantage of the invention is that despite a ring-shaped appearance of the lamp by Seitenlichtablenkmittel a larger lateral light deflection is possible. In this case, an annular or circular-segment-shaped partial light bundle is deflected in a preferred lateral direction, so that the illumination function, preferably the annular illumination function, can be recognized from lateral viewing directions. Advantageously, the lamp can be designed as a flashing light, so that the safety in traffic can be increased by the improved lateral visibility.
Nach einer bevorzugten Ausführungsform sind die Lichtablenkmittel derart angeordnet, dass ein zusätzliches Teillichtbündel erzeugt wird, das im Wesentlichen in horizontaler Richtung zu einer Fahrzeugaußenseite abgelenkt wird. Hierdurch kann die Erkennbarkeit der Leuchtfunktion durch Verkehrsteilnehmer erhöht werden, die sich in einem relativ steilen Winkel zur Fahrzeuglängsachse des Fahrzeugs befinden.According to a preferred embodiment, the light deflecting means are arranged such that an additional partial light bundle is generated, which is deflected in a substantially horizontal direction to a vehicle outer side. In this way, the visibility of the lighting function can be increased by road users who are at a relatively steep angle to the vehicle longitudinal axis of the vehicle.
Nach einer ersten Variante der Erfindung ist das Lichtablenkmittel an einer in radialer Richtung inneren Randseite eines aus einer Mehrzahl von ringförmig angeordneten Reflektoren gebildeten Reflektorrings angeordnet. Die Seitenlichtablenkmittel sind – wie die Leuchtdioden und die Reflektoren – konzentrisch angeordnet, wobei jedem Reflektor ein Seitenlichtablenkmittel zugeordnet ist. Vorteilhaft wird durch die Seitenlichtablenkmittel direkt von der Leuchtdiode abgestrahltes Licht in den Seitenbereich umgelenkt. Neben der Blinklichtfunktion kann hierdurch auch eine Seitenmarkierungslichtfunktion erzeugt werden.According to a first variant of the invention, the light deflection means is arranged on a radially inner edge side of a reflector ring formed from a plurality of annularly arranged reflectors. The Seitenlichtablenkmittel are - like the light emitting diodes and the reflectors - arranged concentrically, each reflector is associated with a Seitenlichtablenkmittel. Advantageously, by the Seitenlichtablenkmittel directly emitted by the light emitting diode light is deflected into the side area. In addition to the flashing light function, this can also be used to generate a side marker light function.
Nach einer weiteren Variante der Erfindung ist das Lichtablenkmittel als ein tubusförmiger Lichtleiter ausgebildet, der entlang einer optischen Achse der diesem zugeordneten Leuchtdiode verläuft. In dem tubusförmigen Lichtleiter wird das direkt von der Leuchtdiode abgestrahlte Licht eingekoppelt, an der Mantelfläche totalreflektiert und über eine abgeschrägte Flechte in die Vorzugsrichtung ausgekoppelt. Vorzugsweise ist die Lichtauskoppelfläche des tubusförmigen Lichtleiters derart ausgebildet, dass nur ein Teil in seitlicher Richtung abgelenkt wird, ein anderer Teil nach vorne hin ausgekoppelt wird. Hierdurch wird gewährleistet, dass die Beleuchtungsstärke in axialer Richtung nicht zu stark eingeschränkt wird.According to a further variant of the invention, the light deflecting means is designed as a tube-shaped optical waveguide which runs along an optical axis of the light-emitting diode associated therewith. In the tubular optical waveguide, the light emitted directly by the light-emitting diode is coupled in, totally reflected on the lateral surface and coupled out via a bevelled lichen in the preferred direction. Preferably, the light outcoupling surface of the tubular light guide is designed such that only a part is deflected in the lateral direction, a other part is decoupled forwards. This ensures that the illuminance in the axial direction is not restricted too much.
Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further advantages of the invention will become apparent from the further subclaims.
