Description

光源装置及投影系统 技术领域
本实用新型涉及一种光源装置及投影系统。
 背景技术
目前，在投影以及照明领域都开始越来越广泛的应用激光光源，由于具有能量密度高，光学扩展量小的优势，在高亮度光源领域，激光光源已经逐渐取代灯泡和LED光源。而在这其中，采用蓝光激光作为激发光源激发黄色荧光粉产生白光的光源装置，以其光效高、稳定性好、成本低等优点成为应用的主流。
请参阅图1，图1是一种现有技术白光光源装置100的光路结构示意图。该光源装置100具有采用蓝光+黄光两路光合光的形式，其包括激发光源101、107、中继透镜102、108、收集透镜104、110、透蓝反黄膜片103、111、波长转换装置105、散射片109及反射镜106。
所述激发光源101发出第一蓝色激发光，所述第一蓝色激发光依序经由所述中继透镜102、所述透蓝反黄膜片103、所述收集透镜成像到所述波长转换装置105。所述波长转换装置105为旋转的反射式黄色荧光粉色轮，其受所述第一蓝色激发光激发黄色受激光。所述黄色受激光被反射后穿过所述收集透镜104并在所述透蓝反黄膜片103处被反射，并在传播过程中经所述反射镜106反射后，到达所述透蓝反黄膜片111处。所述激发光源107发出第二蓝色激发光，所述第二蓝色激发光经所述中继透镜108汇聚到所述散射片109处，所述第二蓝色激发光被散射后消相干经所述收集透镜110收集后出射，到达所述透蓝反黄膜片111处。所述黄色受激光与所述第二蓝色激发光在所述透蓝反黄膜片111处合光，形成白光出射。
该光源装置100采用蓝光+黄光两个独立的光路，最终合光从而能够得到较好的白光，但系统过于复杂，体积大，成本高，很难做小型化。
请参阅图2，图2是另一种现有技术白光光源装置200的光路结构示意图。所述光源装置200包括激发光源201、分光装置202、收集透镜203、205、散射粉片204、及波长转换装置206。所述激发光源201发出蓝色激发光，所述分光装置202，将一部分蓝色激发光反射，所述部分蓝色激发光经过收集透镜203收集后入射到所述散射粉片204上，进一步被散射和反射后经收集透镜203准直出射。另一部分蓝色激发光在所述分光装置202处透射，所述另一部分蓝色激发光经过收集透镜205收集后入射到具有黄色荧光粉的波长转换装置206上，激发黄色荧光粉产生黄色受激光，所述黄色受激光经收集透镜205准直出射。准直的部分蓝色激发光和黄色受激光在所述分光装置202处合光，形成白光光束。
 技术问题
然而，所述光源装置200中，按照白光中的蓝光和黄光配比要求，一般在所述分光装置202处反射的蓝色激发光为15%，透射比例为85%，则经过所述散射粉片204反射回来的部分蓝色激发光中，有15%会在所述分光装置202处反射损失。同时，在所述波长转换装置206处，有相当一部分蓝色激发光未被吸收，入射到所述分光装置202处，其中的85%会透射损失，因此，在所述分光装置202处损失的蓝光较多，导致系统的光效不够高。同样，在采用上述图1及图2的架构进行合光但发出非白光（如橘色、蓝色等其他颜色光）的光源装置同样也存在结构较为复杂、光效较低的问题。

所述第一区域3051还接收所述波长转换装置309反射的部分第二部分激发光，由于所述第一区域3051对所述激发光进行透射，因此所述波长转换装置309反射的部分第二部分激发光会通过所述第一区域3051并损失掉。所述第一区域3051还接收并对所述波长转换装置309发出的受激光进行反射，并将反射后的受激光提供至所述出光通道312。由于所述第一区域3051还对所述补充光源307发出的补充光进行透射并提供到所述出光通道312上，因此，所述第一区域3051还将所述补充光与部分受激光进行合光并提供到所述出光通道312上。
所述第二区域3052还接收所述波长转换装置309反射的另一部分的第二部分激发光，并对所述激发光进行反射，因此所述波长转换装置309反射的另一部分的第二部分激发光会通过被所述第二区域3052反射至所述出光通道312，从而所述第二部分激发光可以被提供至所述出光通道312中继续利用，提高整个光源装置300的光利用率。所述第二区域3052也接收并对所述波长转换装置309发出的受激光进行反射，并将反射后的受激光提供至所述出光通道312。由此，所述第二区域3052将所述受激光与所述第二部分的激发光进行合光所述出光通道312上。进一步地，所述第一区域3051与所述第二区域3052共同作用将所述第二部分的激发光、所述受激光、及所述补充光进行合光并提供到所述光源装置300的出光通道312中。

具体地，本实施方式中，当所述激发光为蓝色激发光时，所述波长转换装置309包括黄色荧光材料，所述受激光为黄色受激光，所述补充光为蓝色补充光。所述受激光、所述第二部分激发光及所述补充光合光成白光。所述第一区域3051透射所述蓝色激发光及所述蓝色补充光并且反射所述黄色受激光，所述第二区域3052透射所述蓝色补充光并反射所述黄色受激光及所述蓝色激发光。本实施方式中，所述蓝色激发光与所述蓝色补充光的波长范围不交叠。其中，所述蓝色激发光的波长可以小于450nm，所述补充光的波长可以为大于450nm而小于500nm。

所述补充光源407的加入还拓宽了所述光源装置400的发光光谱，通过有效调节激发光、补充光及受激光也可以有效的提高光源装置400发出的光线颜色的均匀性，所述光源装置400的光线颜色均匀性较好。
本实用新型还提供一种投影系统，所述投影系统可以应用于投影机、LCD(Liquid Crystal Display，液晶显示器)显示等，所述投影系统可以包括光源装置、光调制装置及投影镜头，所述光源装置采用上述实施方式中的光源装置300或400。所述光调制装置用于依据所述光源装置发出的光线及输入图像数据调制图像而输出调制图像光线，所述投影镜头用于依据所述调制图像光线进行投影而显示投影图像。采用上述光源装置300或400的投影系统的光利用率较高，图像的颜色均匀性较好。
另外，可以理解，本实用新型光源装置300及400还可以用于舞台灯系统、车载照明系统及手术照明系统等，并不限于上述的投影系统。
以上所述仅为本实用新型的实施例，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本实用新型的专利保护范围内。
