Title (EN) DUAL COLOR LASER LIGHT SOURCE AND LASER PROJECTOR
(FR) SOURCE DE LUMIÈRE LASER À DEUX COULEURS ET PROJECTEUR LASER
(ZH) 双色激光光源和激光投影机
Abstract:
(EN) A dual color laser light source and a laser projector. The laser light source comprises a light composition member (24) used to shine a first blue laser light onto a phosphor wheel (23), and to reflect green fluorescent light, produced when the first blue laser light irradiates a green fluorescent light region (Y), to a light collecting member (25). The light composition member (24) is further used to shine a second blue laser light onto the light collecting member (25), and to reflect a red laser, emitted by a red laser emitter (102) and shone by a shining region, to the light collecting member (25). The optical circuit system is simple and has a low volume.
(FR) L'invention concerne une source de lumière laser à deux couleurs et un projecteur laser. La source de lumière laser comprend un élément de composition de lumière (24) utilisé pour projeter une première lumière laser bleue sur une roue de luminophore (23), et pour réfléchir la lumière fluorescente verte, produite lorsque la première lumière laser bleue irradie une région de lumière fluorescente verte (Y), vers un élément de collecte de lumière (25). L'élément de composition de lumière (24) est en outre utilisé pour projeter une seconde lumière laser bleue sur l'élément de collecte de lumière (25), et pour réfléchir une lumière laser rouge, émis par un émetteur laser rouge (102) et projeté par une région de projection, vers l'élément de collecte de lumière (25). Le système de circuit optique est simple et présente un volume faible.
(ZH) 一种双色激光光源和激光投影机。激光光源中的合光部件(24)用于将第一蓝色激光透射至荧光轮(23),并将由第一蓝色激光照射绿色荧光区(Y)所产生的绿色荧光反射至光收集部件(25);还用于将第二蓝色激光透射至光收集部件(25);还用于将由红色激光发射器(102)发出并经由透射区透射的红色激光反射至光收集部件(25)。该光路系统较为简单,体积较小。
