Abstract

一种投影光源（10）和投影设备，属于光电技术领域。投影光源（10）中，合光镜片（103）包括多个透射区（1031a、1031b）和多个反射区（1032a、1032b）；荧光轮（105）包括第一区（1051）和设置有光扩散部的第二区（1052）；激光器（101）射出多束激光，多束激光（101）分别射向多个透射区（1031a、1031b），并通过透射区（1031a、1031b）射向会聚透镜（104）；任两束激光在会聚透镜（104）上形成的光斑关于会聚透镜（104）的光轴（h）均不对称；会聚透镜（104）用于将射入的激光会聚向荧光轮（105）；第一区（1051）在被激光照射时被激发出荧光，荧光穿过会聚透镜（104）射向反射区（1032a、1032b）；第二区（1052）在被激光照射时，光扩散部对激光进行扩散，以使扩散后的激光穿过会聚透镜（104）射向反射区（1032a、1032b）；反射区（1032a、1032b）用于沿目标方向反射射入的光。
