Abstract

一种投影光源（10）和投影设备，投影光源（10）中合光镜片（103）包括反射区（1032）以及分别位于反射区（1032）两侧的两个透射区（1031a、1031b）；荧光轮（105）包括第一区（1051）和第二区（1052），第二区（1052）上设置有光扩散部；激光器（101）用于射出多束激光，多束激光射向合光镜片（103）的两个透射区（1031a、1031b），使激光透射向会聚透镜（104）；会聚透镜（104）将激光会聚向荧光轮（105）；荧光轮（105）被配置为绕转轴（Z）旋转，在荧光轮（105）的旋转过程中荧光轮（105）中的不同区接受会聚后的激光的照射；第一区（1051）被激发出激光，且荧光穿过会聚透镜（104）射向反射区（1032）；第二区（1052）的光扩散部对会聚后的激光进行扩散，扩散后的激光穿过会聚透镜（104）射向反射区（1032）；反射区（1032）沿目标方向（X）反射射入的光。投影光源（10）的体积较小，射出的光的均匀性较高，有利于投影设备的投影画面的显示。
