Title (EN) INFRARED EMITTING DEVICE
(FR) DISPOSITIF ÉMETTEUR D'INFRAOUGES
Abstract:
(EN) The present invention addresses an infrared emitting device. The device comprises a light source (100) emitting a first light (104), and a wavelength converting structure ({102; 108}) disposed in a path of light emitted by the light source. The wavelength converting structure comprises a first phosphor (108) that emits infrared light ({110; 112}), and a second phosphor (102) that absorbs the first light (104) and emits a second light (106), which second light is visible light. The first phosphor (108) absorbs the first light (104) and emits a third light (112). The first phosphor (108) also absorbs the second light (106) and emits a fourth light (110). The third light (112) and the fourth light (110) have different peak wavelengths in the infrared emission range.
(FR) La présente invention concerne un dispositif émetteur d'infrarouges. Le dispositif comprend une source de lumière (100) émettant une première lumière (104) et une structure de conversion de longueur d'onde ({102 ; 108}) disposée dans un trajet de lumière émis par la source de lumière. La structure de conversion de longueur d'onde comprend un premier luminophore (108) qui émet une lumière infrarouge ({110 ; 112}) et un second luminophore (102) qui absorbe la première lumière (104) et émet une deuxième lumière (106), laquelle deuxième lumière est une lumière visible. Le premier luminophore (108) absorbe la première lumière (104) et émet une troisième lumière (112). Le premier luminophore (108) absorbe également la deuxième lumière (106) et émet une quatrième lumière (110). La troisième lumière (112) et la quatrième lumière (110) ont des longueurs d'onde de pic différentes dans la plage d'émission infrarouge.
