本实施例以蓝光的激发和传导进行描述。事实上，本公开适用于任何波长范围内的光的激发和传导。
如图1、图3和图5所示，本公开的实施例提供的波长转换装置，可以包括：基体100、光传导器件200和驱动器件300；基体100可以设有光传导部110和波长转换部120；驱动器件300与基体100传动连接，以使光传导部110和波长转换部120交替地位于光传导器件200的预设光路中。
具体地，光传导器件200可以包括光积分棒或者光反射器件，当激发光经光传导部110射入光传导器件200后，蓝光经光传导器件200射出；当激发光沿预设光路射入波长转换部120时，波长转换部120能够将激发光转换成受激光，并使受激光射出。
在本公开的一些实施例中，驱动器件300可以采用气缸，气缸驱动基体100沿垂直于预设光路的方向往复移动，光传导部110和波长转换部120可以沿基体100的移动方向依次设置，从而可以使光传导部110和波长转换部120交替地位于预设光路中。
如图1、图2、图3和图4所示，本实施例中，基体100可以围设形成容纳区101；沿容纳区101的周向，基体100上可以依次设有光传导部110和波长转换部120；驱动器件300可以配置为驱动基体100绕该基体自身的轴线进而绕光传导器件200转动。其中，驱动器件300可以包括电动机，电动机的定子可以连接机架，电动机的转子可以连接基体100。通过驱动器件300驱动基体100绕容纳区101的轴线转动，从而可以使光传导部110和波长转换部120依次经过光传导器件200的预设光路。采用基体100围设形成容纳区101且容纳区101的横截面基本上为圆形的形式，通过驱动基体100绕该基体自身的轴线旋转，切换光传导部110和波长转换部120交替地位于预设光路中的方式，相比于驱动基体100往复移动的方式，围设形成容纳区101的基体100可以具有更大的尺寸，散热性能更好，且具有更高的转换效率。
进一步的，光传导器件200可以连接机架或电动机的定子，激发光沿光传导器件200的预设光路射入波长转换装置，在光传导部110和波长转换部120交替切换过程中，光传 导器件200的位置相对于入射光固定不动，从而可以避免因光传导器件200偏转导致的出光偏斜或蓝光损失。
如图1和图2所示，光传导器件200可以包括光反射器件；光反射器件可以配置为：在光传导部110设于预设光路中的状态下，使经光传导部110射入光反射器件的光线反射，并经光传导部110射出。其中，光反射器件可采用蓝光反射镜；或者，在基材表面粗化、涂覆反射涂层或镀膜等方式形成光反射器件，从而使光反射器件具有较高的漫反射率。
具体的，当光传导部110位于预设光路中，蓝光经光反射器件镜面反射、漫反射或者散射后，经光传导部110射出；当波长转换部120位于预设光路中，波长转换部120将激发光转换成受激光，并由波长转换部120表面的漫反射层反射。在切换光传导部110和波长转换部120交替地位于预设光路的过程中，蓝光和受激光依次自波长转换装置射出，无需转换短波激发光以获得蓝光，且便于引导蓝光与受激光合光。
进一步的，波长转换装置还可以包括蓝光波长转换元件，蓝光波长转换元件可以设置在光传导器件200的预设光路中，配置成将激发光转换成含有长波蓝光的受激光。
进一步的，波长转换装置还可以包括偏振转换元件，偏振转换元件可以设置在光传导器件200的预设光路中，配置成使光反射器件反射的激发光转换偏振状态。
进一步的，光传导部110可以包括透光缺口；经透光缺***入光反射器件的光线被光反射器件反射，并经透光缺***出。其中，光线经透光缺***入光反射器件，经光反射器件反射的蓝光经透光缺***出，无需分别设置进光口和出光口，从而使透光缺口占用基体100表面的面积减小，以此为波长转换部120留存较大的布置空间。
进一步的，基体100可以通过旋转以使透光缺口和波长转换部120交替地位于预设光路中；相对于基体100的旋转轴线，透光缺口对应的圆心角可以小于90度。其中，透光缺口对应的圆心角可以为30度、32度、35度、40度、45度、60度或者75度，可以根据基体100的旋转速度和所需的蓝光量增大或缩小透光缺口对应的圆心角。例如，在基体100的旋转速度一定的条件下，若所需蓝光量较大，则增大透光缺口对应的圆心角，从而增加基体100的每一旋转周期内光反射器件反射蓝光的时长。需要说明的是，为使透光缺口对应的圆心角小于90度，应将光反射器件设置在基体100的旋转轴线和透光缺口之间，从而使光反射器件接近透光缺口，以便使自透光缺***入光反射器件的蓝光，经光反射器件反射后能够经透光缺***出。
如图3、图4和图5所示，光传导器件200可以包括光积分棒。具体的，当光传导部110设于光传导器件200的预设光路中时，光线经光传导部110射入光积分棒，蓝光自光积分棒的一端射入，经光积分棒匀化后从光机分棒的另一端射出。
进一步的，光传导部110可以包括：第一透光口111和第二透光口112；沿容纳区101的周向，第一透光口111和第二透光口112间隔地设置在基体100上；在光传导部110设于预设光路中的状态下，光积分棒可以自第一透光口111向第二透光口112延伸。其中，当基体100旋转期间光传导部110位于光传导器件200的预设光路中时，光积分棒自第一透光口111向第二透光口112延伸。第一透光口111的开口面积可以大于光积分棒的端口面积，第二透光口112的开口面积可以大于光积分棒的端口面积，从而可以调节每一周期内光积分棒的进光时长。光线经第一透光口111和第二透光口112中之一射入光积分棒，经光积分棒匀光处理后的蓝光经第一透光口111和第二透光口112中的另一透光***出。
进一步的，容纳区101的横截面基本上为圆形，光积分棒沿容纳区101的任一直径延伸。基体100围设形成横截面基本上为圆形的容纳区101，光积分棒沿容纳区101的径向延伸，基体100绕该基体自身的轴线旋转一圈可以使光传导部110两次位于光积分棒的光路中。
进一步的，沿光积分棒的延伸方向，光积分棒两端的端面可以均平行于基体100的旋转轴线。自第一透光口111和第二透光口112中之一射入的光线，沿光积分棒传输，且传输方向垂直于基体100的旋转轴线。
进一步的，第一透光口111与第二透光口112可以相对于基体100的旋转轴线中心对称；波长转换部120可以包括偶数段波长转换区，一部分波长转换区与另一部分波长转换区可以相对于第一透光口111与第二透光口112的中心连线对称。
如图2和图4所示，当波长转换部120位于光传导器件200的预设光路中时，波长转换部120可以阻挡激发光射入光传导器件200，激发光经波长转换部120转换为受激光并被反射。
如图2、图4和图6所示，在本公开的一种实施方式中，波长转换部120可以包括偶数段波长转换区。例如：波长转换部120可以包括：第一转换区121、第二转换区122、第三转换区123和第四转换区124，其中，第三转换区123、第一透光口111、第二转换区122、第一转换区121、第二透光口112和第四转换区124可以依次沿基体100设置。第一转换区121和第三转换区123均配置为绿光波长转换区，第二转换区122和第四转换区124均配置为红光波长转换区，在基体100围设形成容纳区101的条件下，基体100绕该基体自身的轴线进而绕光传导器件200旋转可以使第三转换区123、第一透光口111、第二转换区122、第一转换区121、第二透光口112和第四转换区124依次位于光路的入光侧。
如图2、图4和图7所示，在本公开的另一种实施方式中，波长转换部120可以包括：第一转换区121、第二转换区122、第三转换区123、第四转换区124、第五转换区125和 第六转换区126，其中，第一透光口111、第六转换区126、第五转换区125、第四转换区124、第二透光口112、第三转换区123、第二转换区122和第一转换区121可以依次沿基体100设置。第三转换区123和第六转换区126均配置为红光波长转换区，第二转换区122和第五转换区125均配置为黄光波长转换区，第四转换区124和第一转换区121均配置为绿光波长转换区。在基体100围设形成容纳区101的条件下，基体100绕该基体自身的轴线进而绕光传导器件200旋转可以使第一转换区121、第二转换区122、第三转换区123、第四转换区124、第五转换区125和第六转换区126依次位于光路的入光侧。
在本公开的一种实施方式中，波长转换装置还可以包括蓝光波长转换元件，蓝光波长转换元件可以设置在光传导器件200的预设光路中，配置成将激发光转换成含有长波蓝光的受激光。蓝光波长转换元件可以配置为涂覆在光传导器件200上的蓝光波长转换材料，可以将部分或全部激发光转换成含有长波蓝光的受激光，长波蓝光可降低波长转换装置出光对人眼的刺激。需要说明的是，若光传导器件200采用光反射器件，则蓝光波长转换元件可采用涂覆于反射基材的蓝光波长转换材料，还可以将蓝光波长转换材料增设在漫反射涂层中；若光传导器件200采用光积分棒，则蓝光波长转换元件采用透明的基材。在本公开的另一种实施方式中，波长转换装置还可以包括偏振转换元件，偏振转换元件设置在光传导器件200的预设光路中，偏振转换元件可以将光反射器件反射的激发光转变成与原激发光不同的偏振态。

具体地，在驱动器件300驱动基体100，以切换光传导部110和波长转换部120交替地位于预设光路的过程中，光传导器件200可以相对于激发光源400位置固定，从而可以避免因光传导器件200偏移而导致蓝光损失或偏斜。
在本公开的实施例中，光影处理设备还可以包括：二向色元件500和光整理组件600；光整理组件600可以配置成处理波长转换装置射出的蓝光和/或受激光，并使其射入二向色元件500；蓝光和受激光经二向色元件500合光并射出。其中，二向色元件500能够反射第一种偏振特性的蓝光，并能够透射与第一种特性的蓝光的偏振方向垂直的第二种偏振特性的蓝光，且可以反射或透射波长转换材料转换的受激光。

在本公开的上述实施例中，波长转换装置的光反射器件与二向色元件500夹角为45度，经波长转换装置射出的蓝光和受激光分别射入光整理组件600，经光整理组件600处理后的蓝光和受激光射入二向色元件500合光并射出。
具体的，光整理组件600可以包括偏振转换器610，激发光源400发出的光线经偏振转换器610处理，转换成另一种偏振特性的激发光，经过转换偏振特性后的激发光入射到波长转换装置上，当光传导部110位于预设光路中，激发光透过光传导部110射入光传导器件200，然后射回至偏振转换器610，从而转换成与射入偏振转换器610的激发光偏振方向垂直的蓝光，蓝光由二向色元件500通过反射或透射射出。此外，光整理组件600还可以包括第一透镜620，第一透镜620可以采用凸透镜，通过第一透镜620处理射入波长转换装置或经波长转换装置射出的光线。
进一步的，激发光源400可以包括：光源器件410、第二透镜420、第三透镜430和匀光装置440，其中，光源器件410、第二透镜420、第三透镜430和匀光装置440可以依次设置，第二透镜420、第三透镜430和匀光装置440可以共同处理光源器件410发出的激发光，并使激发光射入二向色元件500。波长转换装置可以增设补偿光源700，补偿光源700发出的光线射入二向色元件500，经二向色元件500处理后的光线射入光整理组件600，并经光整理组件600处理射入波长转换装置。
如图1、图2、图3、图4和图5所示，本公开的实施例提供的光处理方法可以包括：将激发光沿光传导器件200的预设光路射向波长转换装置；驱动基体100可以相对于光传导器件200旋转或移动，并使光传导部110和波长转换部120交替地位于预设光路中。当光传导部110位于预设光路中，激发光经光传导部110射入光传导器件200，经光传导器件200处理后的蓝光射出；当波长转换部120位于预设光路中，波长转换部120可以将激发光转换为受激光并被反射。通过光传导部110和波长转换部120交替地位于预设光路中，从而可以使蓝光和受激光以一定时序依次射出，无需增设蓝光补偿光路，且便于引导受激光与蓝光合光。
最后应说明的是：以上各实施例仅用以说明本公开的技术方案，而非对其限制；尽管参照前述各实施例对本公开进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本公开各实施例技术方案的范围。
工业实用性：
本公开采用基体设有光传导部和波长转换部，通过驱动器件与基体传动连接，以使光传导部和波长转换部交替地位于光传导器件的预设光路中，本公开提供的波长转换装置，应用于蓝光激发时，无需增设用于蓝光补偿的激光器，可以解决波长转换装置缺蓝光的技术问题，有利于简化光路结构。采用基体围设形成容纳区且容纳区的横截面基本上为圆形的形式，通过驱动基体绕基体自身的轴线旋转，切换光传导部和波长转换部交替地位于预设光路中的方式，相比于驱动基体往复移动的方式，围设形成容纳区的基体可以具有更大的尺寸，散热性能更好，且具有更高的转换效率。
