Title (EN) WHITE LIGHT EMITTING DIODE BASED ON MIXING OF TRI-COLOR PHOSPHORS
(FR) DIODE A EMISSION DE LUMIERE BLANCHE FONDEE SUR LE MELANGE DE PHOSPHORES TRICOLORES
Abstract:
(EN) The present invention relates to a white emitting diode based on the mixing of tri-color phosphors, more particularly to a light emitting diode prepared by coating red, green and blue phosphors (3) on a UV light emitting diode chip (1) and transmitting light, which is characterized in that each of the red, green and blue phosphors absorbs light in the specific wavelength region from 380 to 410 nm and is comprised at a specific proportion to obtain the phosphor mixture, thereby offering improved light emitting intensity, superior white light and a high efficiency.
(FR) Cette invention concerne une diode à émission de lumière blanche fondée sur le mélange de phosphores tricolores. Plus particulièrement, cette invention concerne une diode à émission de lumière blanche préparée par dépôt de phosphores rouge, vert et bleu sur une puce de diode à émission de lumière UV puis transmission de la lumière, qui se caractérise par des phosphores rouge, vert et bleu émettant une lumière dans la zone de longueur d'onde spécifique comprise entre 380 et 410 nm et qui est contenu dans une proportion spécifique permettant d'obtenir le mélange des phosphores, offrant ainsi une intensité lumineuse améliorée, une meilleure qualité de lumière blanche et une efficacité élevée d'au moins 10 mW.
