Technical Problem
[0005]本实用新型的目的在于提供一种具有照明和投影双用途的激光荧光光源，解决了现有技术中的激光荧光光源存在无法实现照明和投影双用途的问题
Benefits of technology
本实用新型提供的一种具有照明和投影双用途的激光荧光光源，通过设置具有第一色环带与第二色环带的荧光色轮，并配合切换结构控制其位置，实现投影光源模式与照明光源模式的自由切换，从而使同一光源系统可兼顾显示与照明两种功能，大幅提升设备利用率。通过设置合光元件，能够有效反射蓝色激光并透射荧光，使激发光与受激荧光高效叠加形成白光输出，简化了光路结构，减少光损失，提高整体光效。在投影模式下，蓝色激光经匀光器件与收光透镜组处理后，获得均匀、高亮度且色彩准确的光源输出，确保投影图像的高亮度、高对比度与广色域表现。在照明模式下，通过选择性切换至不同荧光色环带，可获得白光输出，有效消除激光散斑，实现高亮度、色彩自然的照明效果。通过设置反射镜组，可将穿过荧光色轮的蓝光重新引导回合光元件，提高了蓝光利用率，避免能量浪费；同时旋转荧光色轮结构散热均匀，保证系统长期稳定运行。因此，本实用新型解决了现有技术中的激光荧光光源无法实现照明和投影双用途的问题。
