Abstract

一种激光投影设备（10），其应用的激光器组件具有第一出光区域（1101），第二出光区域（1102）和第三出光区域（1103），分别发出第一颜色激光光束，第二颜色激光光束和第三颜色激光光束；合光镜组（120），包括多个合光镜片（1201,1202,1203），分别对应第一出光区域（1101），第二出光区域（1102）和第三出光区域（1103）设置，用于将上述出光区域出射的激光光束合光并向光源（100）出光口出射；其中，第一颜色激光光束、第二颜色激光光束的光束角度与第三颜色激光光束合光后的光束角度大于从第一出光区域和第二出光区域直接出射的光束角度，且均小于等于第三颜色激光光束的光束角度。
