Abstract
(EN)
A light source system (100) and a projection device (200) comprising the light source system (100). The light source system (100) comprises: a laser group (10), wherein at least part of the laser light emitted by the laser group (10) is used as primary color light of the light source system (100); and a light homogenizing element (20), arranged on a light emergent path of the laser light emitted by the laser group (10) and used as the primary color light, and used for homogenizing the laser light used as the primary color light of the light source system (100).
(FR)
La présente invention concerne un système de source de lumière (100) et un dispositif de projection (200) comprenant le système de source de lumière (100). Le système de source de lumière (100) comprend : un groupe laser (10), au moins une partie de la lumière laser émise par le groupe laser (10) étant utilisée en tant que lumière de couleur primaire du système de source de lumière (100) ; et un élément d'homogénéisation de lumière (20), disposé sur un trajet d'émergence de lumière de la lumière laser émise par le groupe laser (10) et utilisée en tant que lumière de couleur primaire, et utilisé pour homogénéiser la lumière laser utilisée en tant que lumière de couleur primaire du système de source de lumière (100).
(ZH)
光源系统(100)及包括光源系统(100)的投影设备(200),光源系统(100)包括:激光器组(10),激光器组(10)出射的激光中至少有一部分作为光源系统(100)的基色光;以及匀光元件(20),设置在激光器组(10)出射的作为光源系统(100)基色光的激光出光光路上,用于对作为光源系统(100)基色光的激光进行匀光。
