Abstract
(DE)
Die vorliegende Erfindung schafft eine Beleuchtungseinrichtung (1) zum Abstrahlen von Licht mehrerer Wellenlängen umfassend eine Lichtquelle (10); eine wellenlängenkonvertierende Einrichtung (2), welche in einem Abstrahlbereich der Lichtquelle (10) angeordnet ist, welche zumindest einen ersten Konverterbereich (KB3a, KB3b,..., KB3n) mit einem ersten wellenlängenkonvertierenden Material (3a) und einen zweiten Konverterbereich (KB3a', KB3b',..., KB3n') mit einem zweiten wellenlängenkonvertierenden Material (3b) umfasst, wobei der erste Konverterbereich (KB3a, KB3b,..., KB3n) dazu eingerichtet ist, Licht von der Lichtquelle (10) in eine erste Wellenlänge zu konvertieren und der zweite Konverterbereich (KB3a', KB3b',..., KB3n') dazu eingerichtet ist, Licht von der Lichtquelle (10) in eine zweite Wellenlänge zu konvertieren, wobei die erste und die zweite Wellenlänge verschieden sind, und wobei die Konverterbereiche (KB3a, KB3b',..., KB3n) lateral nebeneinander angeordnet sind.
(EN)
The present invention provides a lighting device (1) for emitting light of a plurality of wavelengths comprising a light source (10); a wavelength-converting device (2), which is arranged in an emission region of the light source (10) and comprises at least one first converter region (KB3a, KB3b,..., KB3n) comprising a first wavelength-converting material (3a) and a second converter region (KB3a', KB3b',..., KB3n') comprising a second wavelength-converting material (3b), wherein the first converter region (KB3a, KB3b,..., KB3n) is configured to convert light from the light source (10) into a first wavelength and the second converter region (KB3a', KB3b',..., KB3n') is configured to convert light from the light source (10) into a second wavelength, wherein the first and the second wavelengths are different, and wherein the converter regions (KB3a, KB3b',..., KB3n) are arranged laterally next to one another.

L'invention concerne un dispositif d'éclairage (1) pour émettre de la lumière à plusieurs longueurs d'onde, lequel comprend : une source de lumière (10) ; un dispositif de conversion de longueurs d'onde (2) disposé dans une zone d'émission de la source de lumière (10), laquelle comprend au moins une première zone de conversion (KB3a, KB3b, ..., KB3n) comprenant un premier matériau (3a) de conversion de longueurs d'onde et une deuxième zone de conversion (KB3a', KB3b', ..., KB3n') comprenant un deuxième matériau (3b) de conversion de longueurs d'onde. La première zone de conversion (KB3a, KB3b, ..., KB3n) est mise au point pour convertir de la lumière provenant de la source de lumière (10) en une première longueur d'onde, et la deuxième zone de conversion (KB3a', KB3b', ..., KB3n') est mise au point pour convertir de la lumière provenant de la source lumineuse (10) en une deuxième longueur d'onde. La première et la deuxième longueur d'onde sont différentes. Les zones de conversion (KB3a, KB3b', ..., KB3n) sont disposées côte à côte latéralement.
