Title (EN) LIGHT SOURCE
(FR) SOURCE DE LUMIÈRE
(ZH) 一种光源
Abstract:
(EN) Provided is a light source (101) applicable to the field of projection and illumination comprising a blue laser source (102) for generating a blue laser; a green light conversion material (103) for generating a green stimulated light under the action of the blue laser; a yellow light conversion material (104) for generating a yellow stimulated light under the action of the blue laser; and a red light filter (105) for filtering the yellow stimulated light into a red stimulated light, wherein the blue laser, the green stimulated light, and the red stimulated light are emitted in time series. In this way, the illumination brightness can be improved and the color rendering property can be improved.
(FR) L'invention concerne une source de lumière (101) pouvant être appliquée au domaine de la projection et de l'éclairage comprenant une source laser bleue (102) destinée à générer un laser bleu; un matériau de conversion de lumière verte (103) destiné à générer une lumière stimulée verte sous l'action du laser bleu; un matériau de conversion de lumière jaune (104) destiné à générer une lumière stimulée jaune sous l'action du laser bleu; et un filtre de lumière rouge (105) destiné à filtrer la lumière stimulée jaune en une lumière stimulée rouge, le laser bleu, la lumière stimulée verte et la lumière stimulée rouge étant émises en série chronologique. De cette manière, la luminosité d'éclairage peut être améliorée et la propriété de rendu des couleurs peut être améliorée.
(ZH) 一种光源(101),可应用于投影领域和照明领域,包括蓝光激光光源(102),用于产生蓝色激光;绿光转换材料(103),用于在蓝色激光的作用下产生绿色受激光;黄光转换材料(104),用于在蓝色激光的作用下产生黄色受激光;红光滤光片(105),用于将黄色受激光过滤成红色受激光,其中蓝色激光、绿色受激光以及红色受激光时序地出射。通过这种方式,能够提高照明亮度,且提升其显色性。
