请参阅图1和图2，本实施例提供一种光学元件固定组件10，光学元件固定组件10用于光源系统，光源系统包括壳体，光学元件固定组件10固定于壳体，光学元件固定组件10包括承载件11、第一光学元件13和第二光学元件15，其中承载件11为一体式结构，第一光学元件13固定于承载件11，第二光学元件15固定于承载件11并与第一光学元件13平行，以使入射光经第二光学元件15和第一光学元件13作用后形成平行的出射光。
具体地，在本实施例中，光学元件固定组件10用于光源系统，光源系统包括壳体，壳体是光源系统的外壳，光学元件固定组件10为独立于壳体的组件，光学元件固定组件10固定于壳体，固定方式可以是螺接等，通过将光学元件固定组件10做成独立组件固定在壳体上，能够方便前期产线对光学元件固定组件10的组装和后期对其维护，节省装配时间，也容易保证光学元件的平行精度。
请继续参阅图1，在本实施例中，承载件11包括第一板111、第二板113和第三板115，其中，第一板111和第二板113平行，第一板111和第二板113的外形可以相同，即第一板111和第二板113可以近似关于第三板115的中轴线对称，这样设置可以使承载件11的工艺更加简单，从而利于承载件11的批量生产。在其他实施方式中，第一板111和第二板113还可以相互倾斜设置。第三板115设置于第一板111和第二板113之间，第三板115的两端可以突出于第一板111 或者第二板113的边缘，还可以与第一板111和第二板113首尾相接。相应地，第一板111或者第二板113也可以突出于第三板115的边缘。第一板111、第二板113和第三板115可为金属材质，可以通过压铸、锻造、轧制等工艺制成整体结构。
第一板111呈大致的平行四边形板状结构，第一板111包括第一端面1112、第一内表面1114和第一外表面1116，其中，第一外表面1116与第一内表面1114相背，第一内表面1114与第三板115直接相连，第一端面1112用于连接于第一内表面1114和第一外表面1116。
第一端面1112和第一外表面1116之间可以通过弧面过渡，通过将第一端面1112和第一外表面1116之间设置成通过弧面过渡相接，可以增加第一板111的边缘的强度。可以理解，第一端面1112和第一内表面1114之间可以通过弧面过渡相接。在本实施例中，第一外表面1116可以和第一内表面1114平行，在其他实施方式中，第一外表面1116与第一内表面1114相互之间还可以呈角度倾斜。
第二板113也呈大致的平行四边形板状结构，第二板113可以与第一板111平行，第二板113包括第二端面1132、第二内表面1134和第二外表面1136，其中，第二端面1132和第二内表面1134相接，第二内表面1134与第三板115直接相连，第二外表面1136与第二内表面1134相背，即第二端面1132连接于第二内表面1134和第二外表面1136之间。第二端面1132和第二外表面1136之间可以通过弧面过渡相接，第二端面1132和第二内表面1134之间也可以通过弧面过渡相接。
第三板115呈大致的矩形板状结构，第三板115连接于第一内表面1114和第二内表面1134之间，第三板115包括相背的第一表面1152和第二表面1153， 其中，第一表面1152连接于第一内表面1114和第二内表面1134之间，第一表面1152可以和第二表面1153平行。第三板115还包括相背的第一侧面1154和第二侧面1156，第一侧面1154可以与第一内表面1114共面，第二侧面1156可以与第二内表面1134共面，第一侧面1154也可以和第二侧面1156平行。
第一光学元件13固定于承载件11，具体地，第一光学元件13可以为大致的矩形板状结构，第一光学元件13可以兼有反射光线和一定的透射光线的功能。第一光学元件13固定于第一板111和第二板113之间。
在其他实施方式中，第一光学元件13还可以直接贴合于第一端面1112和第二端面1132之间。
第二光学元件15固定于承载件11，具体地，在本实施例中，第二光学元件15也可以为大致的矩形板状结构，第二光学元件15可以具有反射光线的功能。第二光学元件15固定于第一板111和第二板113之间。
在其他实施方式中，第二光学元件15还可以直接贴合于第三板115的第一表面1152。第二光学元件15对入射光线进行反射，并将光线反射至第一光学元件13。请参阅图3，光学元件固定组件10可以减小光斑面积，具体表现为，光斑面积较大的光源发出入射光线，入射光线同时入射至第一光学元件13和第二光学元件15，一部分入射光在依次经过第二光学元件15和第一光学元件13的反射后形成部分出射光，另一部分入射光直接透过第一光学元件13与前述部分出射光汇合，从而达到减小光斑面积的作用。
综上，本实施例提供的光学元件固定组件10通过将承载件11设置成一体式结构，使承载件11得以批量生产，并能保证平行精度，方便组装。通过将第二光学元件15与第一光学元件13平行设置，减小了出射的光斑面积，从而达到能量 集中的作用，并提高光效。
请参阅图4，进一步地，承载件11还可以包括第一定位台阶117、第二定位台阶118等结构。
承载件11还包括三个第一定位台阶117，三个第一定位台阶117分别设置于第一端面1112和第二端面1132，即第一端面1112及第二端面1132至少设置有一个第一定位台阶117，例如，第一端面1112设置有两个第一定位台阶117并且第二端面1132设置有一个第一定位台阶117，位于第一端面1112的两个第一定位台阶117相对第一端面1112的位置可以相同，通过将承载件11设置成三点支撑定位结构，对第一光学元件13进行平面支撑。也可以在第一端面1112设置有一个第一定位台阶117并且第二端面1132设置有两个第一定位台阶117，对对第一光学元件13进行平面支撑。在本实施例中，第一定位台阶117的边缘可以位于第一端面1112内部，在其他实施方式中，第一定位台阶117的边缘还可以和第一端面1112的边缘平齐。三个第一定位台阶117的高度可以均相同，从而可以形成支撑面用于支撑其他元件，进而保证光学元件的平整度。
承载件11还包括三个第二定位台阶118，三个第二定位台阶118凸出于第一表面1152，第二定位台阶118分布于第三板115沿第一板111至第二板113方向的两端，位于同侧的至少两个第二定位台阶118可以是无规则地分布于第一表面1152，还可以是按照一定规律，例如线性矩阵或者圆形矩阵等方式排列。三个第二定位台阶118之间的高度可以相同，第二定位台阶118和第一定位台阶117的高度可以相同，这样设置可以减小加工难度，例如铣削加工承载件11时，可以不用切换编程中的台阶高度参数即可从第一台阶直接加工第二台阶。可以理解，第二定位台阶118和第一定位台阶117的高度也可以不同。
请继续参阅图4，承载件11还包括多个第一限位部119和多个第二限位部120，多个第一限位部119设置于第一板111和第二板113的边缘，具体地，在本实施例中，两个第一限位部119分别位于第一端面1112沿垂直于第一板111至第二板113方向的两端，两个第一限位部119之间的距离可以根据实际情况设定，第一限位部119突出于第一端面1112，另外两个第一限位部119分别位于第二端面1132沿垂直于第一板111至第二板113方向的两端，第一限位部119还突出于第二端面1132。在其他实施方式中，第一端面1112可以包括两个第一限位部119并且第二端面1132包括一个第一限位部119，在一种实施方式中，第一端面1112及第二端面1132各包括一个第一限位部119，两个第一限位部119位于承载件11的两端。第一板111和第二板113同侧的两个第一限位部119的位置对应，其中“对应”可以理解为两个限位部的中轴线之间的连线可以和第一端面1112的边界平行。
多个第二限位部120设置于第三板115的边缘，具体地，多个第二限位部120突出于第一表面1152设置，第二限位部120的突出高度可以和第一限位部119的突出高度相同，多个第二限位部120中至少有两个第二限位部120分别位于第一表面1152沿垂直于第一板111至第二板113方向的两端。当第一表面1152的任一侧包括2个、3个或者更多数量的第二限位部120时，同一侧的数个第二限位部120的中心线之间的连线可以位于同一直线上。
请继续参阅图4，承载件11还设置有多个通孔116和多个凹槽114，在本实施例中，多个通孔116均位于第一板111，即多个通孔116相互间隔设置，多个通孔116贯通第一板111的第一外表面1116和第一内表面1114。多个凹槽114在第一板111、第二板113及第三板115均有分布，具体地，多个凹槽114分别 设置于第一板111的第一外表面1116、第二板113的第二外表面1136及第三板115的第一表面1152。在其他实施方式中，多个凹槽114还可以设置于第一板111的第一内表面1114、第二板113的第二内表面1134及第三板115的第二表面1153，通过在承载件11上设置多个通孔116和多个凹槽114，可以减少承载件11的重量并且节省材料成本，从而最终减少包含承载件11的设备的重量。
承载件11还设置有多个避位槽121，多个避位槽121分别设置于第一板111的第一外表面1116和第二板113的第二外表面1136。通过设置多个避位槽121，可以减少承载件11的重量并且节省材料成本，还可以对其他元件进行避位，例如弹性固定件。
请参阅图5，承载件11还包括多个定位孔112，在本实施例中，定位孔112设置在第三板115，定位孔112从第一表面1152贯穿至第二表面1153，定位孔112的数量可以是1个、2个、3个等等，2个或以上数量的定位孔112的中心之间的连线可以和第一表面1152与第一侧面1154的交线平行。在其他实施方式中，定位孔112还可以设置于第一板111或第二板113。通过在承载件11上设置定位孔112可以在制造承载件11时，与加工承载件11的加工机器上的治具进行配合定位，从而更加利于承载件11的制造和批量生产。
请参阅图6，光学元件固定组件10还包括多个弹性固定件17，多个弹性固定件17设置于第一外表面1116、第二外表面1136、第一侧面1154和第二侧面1156，具体地，弹性固定件17包括固定部171和弯折部173，固定部171和弯折部173均可以为片体结构，固定部171设置有三个并列设置的孔(未标示)，其中中间孔可以通过螺钉与承载件11上的孔配合，位于中间孔两侧的另外两个孔与承载件11上的两个凸柱进行配合，以将固定部171固定于承载件11上。弯折 部173和固定部171之间呈锐角连接，使得弯折部173可以与固定部171弹性连接，多个弹性固定件17通过各自的固定部171固定设置于第一外表面1116、第二外表面1136、第一侧面1154和第二侧面1156。
弹性固定件17与第一定位台阶117和第二定位台阶118的数量及位置一一对应，多个弹性固定件17分别与第一定位台阶117和第二定位台阶118相邻设置，使得多个弹性固定件17的弯折部173分别与第一定位台阶117和第二定位台阶118的表面位置对应，即弯折部173朝向第三板115的投影分别落入相应的第一定位台阶117和第二定位台阶118内，并且，多个弹性固定件17的弯折部173分别压在相应的第一光学元件13的位置是关于第一光学元件13的中心是对称的，以保证第一光学元件13固定在承载件上的平整度，同时，多个弹性固定件17的弯折部173分别压在相应的第二光学元件15的位置也是关于第二光学元件15的中心是对称的，以保证第二光学元件15固定在承载件上的平整度，弹性固定件17的材质可以是金属。

请参阅图3，以下以一个具体的示例对本实施例提供的上述承载件11的加工过程进行说明。首先，可以通过压铸成型形成一个毛坯形态的承载件11，即承载件为一体成型结构，对承载件11的边沿进行倒圆等操作，从而增加承载件11边沿的强度；然后对第三板115的第二表面1153进行铣削或抛光等操作，将第二表面1153做成一个近似的平面；并将第二表面1153作为加工定位面，对第一板111进行加工形成第一端面1112和第一端面1112上的第一限位部119，并加工出多个第一定位台阶117，对第二板113进行加工形成第二端面1132和第二端面1132上的第一限位部119，并加工出多个第一定位台阶117，接着继续以第二表面1153作为加工定位面，对第三板115进行加工形成第一表面1152、三个第二定位台阶118及多个第二限位部120，至此形成一个承载件11成品。
