Title (EN) LIGHT-EMITTING APPARATUS WITH SHAPED WAVELENGTH CONVERTER
(FR) DISPOSITIF D'ÉMISSION DE LUMIÈRE AVEC UN CONVERTISSEUR DE LONGUEUR D'ONDE FORMÉ
Abstract:
(EN) Proposed is a light-emitting apparatus 200,300,400, comprising a semiconductor light emitting device 220,320,420 and a transparent ceramic body 230,330,430 comprising a wavelength converting material positioned in light receiving relationship to the semiconductor device. The light-emitting apparatus is characterized in that the side surfaces 233,333,433 of the ceramic body 230,330,430 are at an oblique angle 234,334,434 relative its bottom surface 231,331,431. This is especially advantageous to unlock the wave-guide modes inside the body 230,330,430. Consequently the total flux emitted from the light-emitting apparatus 200,300,400 can be enhanced considerably. Alternatively, the brightness of the top surface 232,332,432 of the ceramic body 230,330,430 can be enhanced considerably.
(FR) La présente invention concerne un dispositif d'émission de lumière 200, 300, 400, comprenant un dispositif d'émission de lumière semi-conducteur 220, 320, 420, et un corps céramique transparent 230, 330, 430, comprenant un matériau de conversion de longueur d'onde positionné en relation de réception de lumière avec le dispositif semi-conducteur. Le dispositif d'émission de lumière est caractérisé en ce que les surfaces latérales 233, 333, 433 du corps céramique 230, 330, 430 sont à un angle oblique 234, 334, 434 par rapport à sa surface inférieure 231, 331, 431. Cela est particulièrement avantageux pour déverrouiller les modes de guide d'onde à l'intérieur du corps 230, 330, 430. Par conséquent, le flux total émis à partir de l'appareil d'émission de lumière 200, 300, 400 peut être augmenté considérablement. En variante, la clarté de la surface supérieure 232, 332, 342 du corps céramique 230, 330, 430 peut être augmentée considérablement.
