Abstract
(EN)
A lighting device according to an embodiment comprises: a white light emitting device comprising at least one first light-emitting diode and a wavelength converter, thereby implementing white light; and at least one second light-emitting diode for emitting light appropriate for killing at least one pathogenic microorganism. The first light-emitting diode emits light having a center wavelength in the range of about 300-420 nm. The second light-emitting diode emits light having a center wavelength in the range of about 400-420 nm. The wave converter comprises wavelength conversion materials for converting the light from the first light-emitting diode into blue light, green light, and red light. The white light implemented by the white light emitting device and the light produced by the second light-emitting diode are emitted outwards. In the radiation luminance spectrum of the white light implemented by the white light emitting device, the radiation luminance of the center wavelength of the light emitted by the first light-emitting diode is smaller than the radiation luminance of the peak wavelength of the blue light emitted by the blue wavelength conversion material.

La présente invention concerne un dispositif d’éclairage selon un mode de réalisation comprenant : un dispositif d’émission de lumière blanche comprenant au moins une première diode électroluminescente et un convertisseur de longueur d’onde, mettant ainsi en œuvre de la lumière blanche ; et au moins une seconde diode électroluminescente pour émettre de la lumière appropriée pour tuer au moins un micro-organisme pathogène. La première diode électroluminescente émet de la lumière ayant une longueur d’onde centrale située dans la plage d’environ 300 à 420 nm. La seconde diode électroluminescente émet de la lumière ayant une longueur d’onde centrale située dans la plage d’environ 400 à 420 nm. Le convertisseur d’onde comprend des matériaux de conversion de longueur d’onde pour convertir la lumière depuis la première diode électroluminescente en lumière bleue, lumière verte, et lumière rouge. La lumière blanche mise en œuvre par le dispositif d’émission de lumière blanche et la lumière produite par la seconde diode électroluminescente sont émises vers l’extérieur. Dans le spectre de luminance de radiation de la lumière blanche mise en œuvre par le dispositif d’émission de lumière blanche, la luminance de radiation de la longueur d’onde centrale de la lumière émise par la première diode électroluminescente est inférieure à la luminance de radiation de la longueur d’onde pic de la lumière bleue émise par le matériau de conversion de longueur d’onde bleue.
