具体地，反射元件13的形状不限，可以是拱桥形，即反射元件13的主视图方向为拱桥状，还可以是中空圆柱形或抛物体形。反射元件13的材质可以是金属、玻璃或者陶瓷等。
请参考图2，匀光元件60和散射元件70均位于多束平行出射光的光路上，散射元件70与匀光元件60固定连接，匀光元件60包括光入射面和和光入射面相对的光出射面，散射元件设置于匀光元件60的出光面，其中散射元件70用于对准直性光源15出射的光束进行消散斑，匀光元件用于对准直性光源出射的光束进行光整形和匀光，可以理解的是，散射元件70可以设置于匀光元件60的光 出射面，也可以设置在匀光元件60的光入射面。
反射元件13包括固定面131和反射面132，通过固定面131可以将反射元件13固定于其他元件上，固定方式可以是粘结或者焊接等。反射面132与固定面131连接。在本实施例中，反射面132可以是抛物面形反射面132，如完整抛物面形或半抛物面形，抛物形反射面132包括焦点P1。在其他实施方式中，反射面132还可以是凹面形，例如反射面132可以是凹面镜的凹面，凹面也可以包括焦点P1。反射面132可以通过在反射元件13上镀高反膜形成。
安装板11的形状可以为规则形的圆形、矩形、跑道形等，还可以是不规则的形状，安装板11可以用于安装发光元件、控制元件等，安装板11还可以作为整个光源装置10的承载板。在一种实施方式中，安装板11可以通过树脂材料模具固化而成，由于树脂材料受热后会软化，因此利于安装板11的机械加工，如钻孔、切割等。在另一种实施方式中，安装板11的材料也可以是金属或陶瓷等高导热材料，以便及时将发光元件产生的热量传递至其他器件，如散热元件等。在又一种实施方式中，安装板11还可以是透明材质，以便将发光元件发出的光束从安装板11导出。
安装板11可以与反射元件13为一体成型结构，如安装板11与反射元件13均为树脂材料时，可以将安装板11与反射元件13作为整体经模具固化形成。如安装板11与反射元件13均为金属材料时，可以通过冲压、CNC(Computerized Numerical Control，计算机数控技术)、抛光等工艺形成。
安装板11包括安装面112和与安装面112相背的底面114，安装面112多束平行出射光平行，安装面112用于安装发光元件或者准直元件等多种元件，底面114可以与安装面112平行。
在本实施例中，安装板11还包括安装孔阵列116，安装孔阵列116包括多个安装孔1162，安装孔阵列116可以是线性阵列，即单排的安装孔1162；也可以是矩形阵列，如多排的安装孔1162；还可以是圆形阵列，如多个安装孔1162组成若干同心圆；还可以是多边形(如五边形、六边形、八边形等)阵列或者螺旋阵列。安装孔1162可以贯通安装面112，例如安装板11为金属时，安装孔阵列116可以通过激光打孔或者干膜蚀刻或湿膜蚀刻形成，又例如安装孔1162为树脂等材料时，安装孔阵列116可以通过机械钻孔等方法形成。安装孔1162的大小可以根据实际情况进行限定。
在其他实施方式中，当安装板11通过树脂材料模具固化形成时，安装板11还可以不开设安装孔1162，即可以在一个模具中根据预先计算好的位置放置需要安装的元件，然后通过树脂填充的方式对该安装元件进行封装成型；这样设置不需要对安装板11进行加工，工艺简单，生产成本较低。
光源装置10包括多个准直性光源15，在本实施例中，准直性光源15可以是激光器，可以是蓝光激光器，还可以是紫光激光器、红光激光器或绿光激光器等。准直性光源15可以包括一个、两个或多个激光器，其中多个激光器还可以形成激光器阵列，具体其激光器的数量可以依据实际需要进行选择，准直性光源15还可以包括匀光器件，用于对激光器发射的光进行均匀化，以满足实际需求。激光器可以为激光二极管(LD)。
在其他实施方式中，准直性光源15还可以包括发光二极管(LED)与准直镜等元件，准直镜用于调整发光二极管发出的光，使得准直性光源15能够发出准直性光束，同样，准直性光源15也可以包括一个、两个或多个发光二极管。
准直性光源15用于发出准直性光束，准直性光束对准反射元件13的焦点P， 以被反射元件13的反射面132反射为多束平行出射光。
请参阅图3，准直性光源15为单个的激光器时，准直性光源15包括相对的发光端152与连接端154，发光端152发出准直性光束，连接端154可以与其他准直性光源15连接，连接端154还可以用于与电源连接。
请参阅图1和图3，多个准直性光源15设置于安装板11，具体地，当安装板11通过树脂材料模具固化，多个准直性光源15可以直接通过树脂填充固定于安装板11的安装面112。
多个准直性光源15可以固定在安装板11的内部，即位于安装面112与底面114之间，当安装板11为非透明材质，此时需要在安装板11的安装面与准直性光源11对应的位置预留出光孔，这样设置可以保护准直性光源15，防止灰尘或者其他外在环境对准直性光源15的干扰。当安装板11为透明材质，此时不需在安装板11的安装面与准直性光源11对应的位置预留出光孔，但应注意安装板材质对准直性光源11的光吸收。
多个准直性光源15还可以设置在安装面112，即准直性光源15的发光端152需要凸出于安装面112或者与安装面112平齐，这样设置可以减少光量的损失。此时安装板11可以为非透明材质。当安装板11为金属材质时，则多个准直性光源15可以分别收容于多个安装孔1162，多个准直性光源15可以一一对应地安装于多个安装孔1162中，可以理解的是，当安装孔1162足够大时，两个或者更多准直性光源15可以收容于同个安装孔1162中。
在本实施例中，光源装置10还可以包括散热座17，散热座17的形状可以为矩形板状、圆形板状或者其他形状，散热座17的面积可以大于安装板11的面积，这样设置能利于光源装置10的稳定放置；也可以和安装板11的面积相等或者小 于安装板11的面积。
散热座17和多个准直性光源15分别设置在安装板11的相背两侧，具体地，散热座17与安装板11固定连接，以将多个准直性光源15发光时产生的热量及时传递至散热座17，散热座17固定于在安装板11的底面114，固定方式可以是通过螺钉拧紧、粘结、焊接或者一体注塑成型设置，具体固定方式可以根据安装板11与散热座17的实际材质进行选择。散热座17还与反射元件13固定连接，以固定反射元件13，防止反射元件13的焦点P1发生偏移，散热座17与反射元件13的连接方式也可以根据散热座17和反射元件13的材质选定。散热座17与安装板11和反射元件13均固定连接，减少了光源装置10的组装难度。
可以理解的是，散热座17、反射元件13和安装板11还可以为一体成型结构，即同时制造得到，二者之间无明显分界。这样设置可以减少光源装置10的组装难度。
请参阅图4和图5，散热座17用于对多个准直性光源15进行散热，使得多个准直性光源15的工作温度维持在一个最佳状态，在一种实施方式中，散热座17可以由铜、铝、铜铝合金等金属及陶瓷等高导热散热材料组成。在另一种实施方式中，散热座17可以包括多个散热片172，多个散热片172位于散热座17的远离安装板11的一侧，多个散热片172可以相互平行设置，散热片172的设置密度依准直性光源15的功率及散热座17的导热能力而设定。在又一种实施方式中，散热座17还可以开设有多条散热通道174，多条散热通道174位于所述散热座17的远离所述安装板11的一侧，散热通道174的多少也可以根据准直性光源15的功率及散热座17的导热能力而设定。
可以理解的是，在其他实施方式中，在散热座17上可以同时设置多条散热 通道174和多个散热片172，多条散热通道174可以位于多个散热片172与安装板11之间。
综上，本实施例提供的光源装置10通过将反射元件13的焦点P1设置在安装板11外，并将设置在安装板11上的多个准直性光源15发射的准直性光束对准反射元件13的焦点P1，使得光源装置10可以出射符合各种场景的合光光斑。
第二实施例
请参阅图6，与第一实施例不同的是，本实施例提供的光源装置40的安装面412和多束平行出射光呈倾斜角度。
具体地，安装面412与多束平行出射光的夹角可以是任意角度，以能够将安装于安装板41上的多个准直性光源45发射的准直性光束对准反射元件43的焦点P2为准。在本实施例中，安装板41可以和多束平行出射光呈倾斜角度，即安装面412可以平行于承载面414。在其他实施方式中，承载面414可以平行于多束平行出射光。安装板41可以固定在反射元件43上与反射元件43共同承载光源装置40。
可以理解的是，本实施例中的上述各技术特征可以相互结合并形成新的实施例。
综上，本实施例提供的光源装置40通过将反射元件43的焦点P2设置在安装板41外，将安装面412设置成与多束平行出射光呈倾斜角度，并将设置在安装板41上的多个准直性光源45发射的准直性光束对准反射元件43的焦点P2，使得光源装置40可以出射符合各种场景的合光光斑。
第三实施例
请参阅图7，与第一实施例不同的是，本实施例提供的光源装置50还包括调 节部59，多个准直性光源55的出光角度可调，所述调节部59用于调节多个准直性光源55的出光角度。
具体地，在本实施例中，调节部59可以安装于散热座57、反射元件53或者安装板51上，调节部59可以直接与准直性光源55连接，调节部59可以是多个，多个调节部59一一对应地收容于安装孔5162中，调节部59还可以安装于散热座57、反射元件53和安装板51之外，具体安装位置可以根据实际需求进行选择。准直性光源55在安装孔5162中动态可调，其中安装孔5162可以开设得适当大些，以便准直性光源55的转动，调节部59可以通过控制准直性光源55的位置，使得准直性光源55相对安装孔5162转动，可以使得准直性光束在经过反射元件53的反射后光束的出射角度发生偏转，从而可以出射动态可调的光斑。调节部59可以是伸缩性的机械结构还可以是一种控制器，通过电信号来控制安装板的运动。
在其他实施方式中，准直性光源55固定在安装孔5162中，调节部59可以调整安装板51的位置，使得安装板51与反射元件53之间的角度发生改变，亦可以使得准直性光束的出射角度发生偏转，从而可以出射动态可调的光斑。
在另外的实施方式中，还可以通过调节部59同时控制准直性光源55的偏转和安装板51的转动。
可以理解的是，本实施例的调节部59也可以应用到第一实施例和第二实施例中，并且可以与上述实施例的各技术特征相互结合并形成新的实施例。
综上，本实施例提供的光源装置50通过将反射元件53的焦点P3设置在安装板51外，将设置在安装板51上的多个准直性光源55发射的准直性光束对准反射元件53的焦点P3，并通过调节部59调节多个准直性光源55的出光角度， 使得光源装置50可以出射符合各种场景的合光光斑。
