Description

一种照明装置 技术领域
本发明属于照明领域，尤其属于固态光源照明领域。本发明提供的一种照明装置可适用于需要高光照强度和小光学扩展量的系统中，比如娱乐照明系统、投影系统、汽车照明系统、医疗照明系统、探照照明系统、野外作业照明系统、航海照明系统、便携式照明系统等。
背景技术
激光作为理想的点光源，具有光学扩展量小、寿命长且不含汞等优点，由它作为光源，激发荧光材料可以得到彩光或者白光，同时配合使用光学元件，可以得到理想的具有较小光学扩展量的照明装置。
图1是现有的偏振分光式照明装置的结构示意图。如图1所示，现有的照明装置包括光源101、四分之一波片102、偏振分光器103、透镜组104(包括透镜104a和透镜104b)、波长转换装置105(包括反射层105a和波长转换层105b)、四分之一波片106、透镜组107(包括透镜107a和透镜107b)、反射式散射板108以及聚焦透镜109。其中，光源101内包含有若干个激光器101a及与若干个激光器101a一一对应的若干个准直透镜101b，激光器101a出射S偏振光的蓝光。
偏振分光器103的特性为反射S偏振光的蓝光且使P偏振光的蓝光透射，同时偏振分光器103还使黄光透射。光源101出射的S偏振光的蓝光透射过四分之一波片102后被转换成由S偏振光成分和P偏振光成分按照规定的比例混合而成的蓝光，然后入射至偏振分光器103。偏振分光器103将其分离成S偏振光的蓝光和P偏振光的蓝光，并且反射其中的S偏振光的蓝光且使其中的P偏振光的蓝光透射。其中，经偏振分光器103反射的S偏振光的蓝光射向透镜组104，透射过偏振分光器103的P偏振光的蓝光射向四分之一波片106。透镜组104使S偏振光的蓝光朝向波长转换装置105会聚。波长转换装置105是反射式的，包括反射层105a和设于反射层105a上的波长转换层105b(比如：黄色荧光粉层)。波长转换装置105将S偏振光的蓝光转换成黄光并使其射向透镜组104，黄光经透镜组104收集后射向偏振分光器103，偏振分光器103使黄光透射。P偏振光 的蓝光透射过四分之一波片106后被转换为圆偏振光的蓝光，透镜组107使圆偏振光的蓝光朝向反射式散射板108会聚，圆偏振光的蓝光经反射式散射板108反射后射向透镜组107，然后经透镜组107收集后射向四分之一波片106。圆偏振光的蓝光透射过四分之一波片106后被转换为S偏振光的蓝光，这些S偏振光的蓝光射向偏振分光器103，偏振分光器103反射S偏振光的蓝光。透射过偏振分光器103的黄光和经偏振分光器103反射的S偏振光的蓝光合为一路混合光，而黄光和蓝光的混合光即为白光。最后，聚焦透镜109使这些白光会聚并从照明装置出射。
在图1所示的方案中，如需显著提升照明装置的光通量的输出，就需要在光源101中增加激光器101a的数量，但这样就会使整个照明装置的光学扩展量变大，从而无法满足一些需要小光学扩展量的应用领域，比如：娱乐照明系统、投影系统等。
