Abstract
(DE)
Die Erfindung betrifft eine optoelektronische Leuchtvorrichtung (100) und ein Verfahren zum Betreiben einer optoelektronischen Leuchtvorrichtung. Die Erfindung schlägt vor, dass eine in einem ersten sichtbaren Wellenlängenbereich emittierende LED (10, 20, 30), eine in einem unsichtbaren Wellenlängenbereich emittierende LED (40) und eine Ansteuereinrichtung (50) bereitgestellt werden, wobei mit der Ansteuereinrichtung die LEDs einzeln ansteuerbar sind. Im Ergebnis wird dadurch eine optoelektronische Leuchtvorrichtung realisiert, mit der eine Zusatzinformation mit der vierten LED generierbar ist, die mit dafür sensitiven Fotodioden darstellbar ist.
(EN)
The invention relates to an optoelectronic lighting apparatus (100) and to a method for operating an optoelectronic lighting apparatus. The invention proposes that an LED (10, 20, 30) emitting in a first visible wavelength range, an LED (40) emitting in an invisible wavelength range and an actuating device (50) are provided, the LEDs being actuatable individually by means of the actuating device. The result is that <b>this</b> realises an optoelectronic lighting apparatus by means of which a piece of supplementary information is generable by means of the fourth LED, which is depictable by means of photodiodes sensitive thereto.
(FR)
L'invention concerne un dispositif d’éclairage optoelectronique (100) et un procédé pour faire fonctionner un dispositif d’éclairage optoélectronique. Selon l'invention, le dispositif comporte une DEL (10, 20, 30) émettant dans une première plage de longueurs d'ondes visibles, une DEL émettant dans une plage de longueurs d'ondes invisibles (40) et un dispositif de commande (50), les DEL pouvant être commandées individuellement au moyen du dispositif de commande. On obtient ainsi un dispositif d’éclairage optoelectronique au moyen duquel une information supplémentaire peut être générée avec la quatrième DEL, qui peut être représentée au moyen de photodiodes sensibles à cet effet.
