 技术问题
虽然反射镜阵列能够压缩各光束之间的距离，但是，为了将入射光转向90度，必须保证各个反射镜与对应的入射光的夹角为45度，这就会对固定反射镜的机械结构的尺寸精度要求较高，导致光源模组的加工难度较大。
 技术解决方案
有鉴于此，本发明提供了一种光源模组和投影设备，以解决现有技术中由于对固定反射镜的机械结构的尺寸精度要求较高而导致的光源模组的加工难度较大的问题。

 附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据提供的附图获得其他的附图。

图2为本发明的一个实施例提供的一种光源模组的结构示意图；
图3为本发明的一个实施例提供的五角棱镜的结构示意图；
图4为本发明的一个实施例提供的另一种光束转向器的结构示意图；

 本发明的最佳实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的一个实施例提供了一种光源模组，如图2所示，该光源模组包括光源阵列1和与光源阵列1对应设置的光束转向器阵列2。
其中，光源阵列1包括多个光源10，光束转向器阵列2包括多个呈阶梯状排列的光束转向器20，且光束转向器20与光源10一一对应设置，也就是说，每一光束转向器20位于对应的一光源10的光路上。
本实施例中，光源10为发射蓝激光的激光器，进一步地，多个光源10排列成方形或圆形等，光源10发射的蓝激光可激发荧光粉发光，以合成投影用的白光。光束转向器20为将入射光线转向特定角度的转向器，其中，在光源10出射的光线以任意角度入射至对应的光束转向器20时，对应的光束转向器20均将该光线转向特定的角度。
可选的，光束转向器20为至少具有第一反射面和第二反射面的棱镜，所述第一反射面和第二反射面的夹角为45度，垂直入射至第一反射面的入射光线被所述第一反射面和第二反射面依次反射后转向90度后出射。
具体地，该光束转向器20为五角棱镜，如图3所示，图3为五角棱镜的截面示意图，该五角棱镜包括依次邻接的第一面a、第二面b、第三面c、第四面d和第五面e，其中，第三面c和第五面e的夹角为45度，第二面b和第三面c的夹角为112.5度，第五面e和第一面a的夹角为112.5度，第一面a和第二面b的夹角为90度。
光源10出射的光线从第一面a进入所述五角棱镜内部后，被第三面c和第五面e依次反射后从第二面b出射，由于第三面c和第五面e的夹角为45度，因此，从第二面b出射的光线与从第一面a入射的光线之间的夹角为90度。也就是说，光源10出射的光线从光束转向器20即五角棱镜的第一面a进入其内部后转向了90度并从第二面b出射。
在某些情况下，如图3中虚线所示，光源10出射的光线从第一面a进入五角棱镜内部后，会被第三面c、第四面d和第五面e依次反射后从第二面b出射，同样，光源10出射的光线从五角棱镜的第一面a进入其内部后转向了90度并从第二面b出射。
本实施例中，五角棱镜的第三面c和第五面e上具有反光条或镀有反射膜，以提高第三面c和第五面e的反射特性，避免光线从第三面c和第五面e透射出去，或者，五角棱镜第三面c、第四面d和第五面e上都具有反光条或反射膜。可选的，所述反光条以胶合的方式粘结在所述五角棱镜上。
本实施例中，通过五角棱镜将光源10出射的光线转向90度，并且，无论光源10出射的光线以何种角度入射至五角棱镜的第一面a，光束均能转向90度出射，因此，不需对光源10出射的光线与第一面a的夹角做严格设定，即不需对固定五角棱镜的机械结构的尺寸精度要求太高，从而可以减小光源模组的加工难度。并且，可通过调整阶梯状排列的各个五角棱镜之间的高度差，来调节各个出射光束之间的间距，实现缩小光源模组尺寸的目的。
在本发明的另一实施例中，如图4所示，图4为本实施例中的一种光束转向器的剖面结构示意图，该光束转向器为梯形棱镜，该梯形棱镜包括依次邻接的第一面a1、第二面b1、第三面c1和第四面d1，其中，第二面b1和第四面d1的夹角为45度。
光源10出射的光线从第一面a1进入图4所示的光束转向器内部后，被第二面b1和第四面d1依次反射后从第一面a1出射，或者，被第二面b1、第三面c1和第四面d1依次反射后从第一面a1出射，其中，从第一面a1出射的光线与从第一面a1入射的光线之间的夹角为90度。
同样，梯形棱镜不需对光源10出射的光线与第一面a1的夹角做严格设定，即不需对固定梯形棱镜的机械结构的尺寸精度要求太高，从而可以减小光源模组的加工难度。
在上述任一实施例的基础上，如图5所示，本发明提供的光源模组还包括位于所述光源阵列1和所述光束转向器阵列2之间的透镜阵列3，所述透镜阵列3包括多个准直透镜30，所述准直透镜30与所述光源10一一对应设置，即每一准直透镜30位于对应光源10的光路上，且所述准直透镜30用于将所述光源10发射的光线会聚准直成平行光束。
在上述实施例的基础上，如图6所示，本发明提供的光源模组还包括聚光透镜4，所述聚光透镜4位于所述光束转向器阵列2的出射光路上，用于会聚准直转向后的平行光束，以使所述平行光束激发不同颜色的光，进行投影画面的显示。
本实施例提供的光源模组，通过光束转向器将光源经过透镜出射的光束转向特定的角度，并且，透镜出射由于光源出射的光束以任意角度入射至光束转向器时，光束转向器均能将光束转向特定的角度，因此，该光束转向器对机械结构的尺寸精度要求较低，从而可以减小光源模组的加工难度。
本发明的另一个实施例提供了一种投影设备，该投影设备包括如上任一实施例提供的光源模组以及荧光色轮等，光源模组出射的光束激发荧光色轮上的荧光粉发光，例如，光源模组出射的光束为蓝激光，荧光色轮上的荧光粉为黄色荧光粉，则未被吸收的蓝激光和激发出的黄光合成投影所用的白光。
本实施例提供的投影设备，通过光束转向器将光源经过透镜出射的光束转向特定的角度，并且，透镜出射由于光源出射的光束以任意角度入射至光束转向器时，光束转向器均能将光束转向特定的角度，因此，该光束转向器对机械结构的尺寸精度要求较低，从而可以减小光源模组的加工难度。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
