Abstract
Description
Die Erfindung betrifft eine Leuchte für Fahrzeuge mit einem Gehäuse, in dem mindestens eine Leuchtdiode als Lichtquelle und ein Reflektor angeordnet sind, und mit einer die Öffnung des Gehäuses abschließenden Abdeckscheibe, und mit Seitenlichtablenkmitteln zur seitlichen Abstrahlung des Lichtes.The The invention relates to a luminaire for vehicles with a housing, in the at least one light emitting diode as a light source and a reflector are arranged, and with a the opening of the housing final cover, and with Seitenlichtablenkmitteln for lateral emission of light.

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.task The present invention is a luminaire with light-emitting diodes as a light source in such a way that at annularly arranged light-emitting diodes an improved lateral light emission is made possible.
Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass die Leuchtdioden im Zusammenwirken mit den Reflektoren ein ringförmiges Erscheinungsbild erzeugen und dass die Seitenlichtablenkmittel derart angeordnet sind, dass ein Teillichtbündel eines zumindest teilweise ringförmig austretenden Lichtbündels zur gleichen Fahrzeuglängsseite hin abgelenkt wird.to solution This object is the invention in conjunction with the preamble of the patent claim 1, characterized in that the light-emitting diodes in cooperation with the reflectors create a ring-shaped appearance and that the side light deflecting means are arranged such that a partial light bundle one at least partially annular emerging light beam to the same vehicle longitudinal side is distracted.
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.Of the particular advantage of the invention is that despite a annular Appearance of the luminaire by sidelight deflection means a larger lateral Light deflection allows becomes. This is an annular or circular ring-shaped Divided light beam deflected in a lateral preferred direction, so that from lateral Viewing directions the lighting function, preferably the annular lighting function, is recognizable. Advantageously, the light as a flashing light be formed, so that through the improved lateral visibility safety in traffic elevated can be.
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.To a preferred embodiment the Lichtablenkmittel arranged such that an additional Divided light beam is generated in a substantially horizontal direction to a Vehicle exterior is distracted. As a result, the recognizability of the lighting function increased by road users be located at a relatively steep angle to the vehicle's 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 can thereby Also, a side marker light function can be generated.
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.To Another variant of the invention is the light deflecting means as a tubular Optical fiber formed along an optical axis of this associated light-emitting diode runs. In the tubular Light guide is the light emitted directly from the light emitting diode coupled, on the lateral surface totally reflected and over a beveled Lichen decoupled in the preferred direction. Preferably, the light coupling of the tubular Optical fiber designed such that only a part in lateral Direction is deflected, another part coupled out to the front becomes. This will ensure that the illuminance is not restricted too much in the axial direction.
Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further Advantages of the invention will become apparent from the other dependent claims.
