 本发明的最佳实施方式
请参见图1和图2，图1是本实用新型光源系统的第一实施例的结构示意图，图2是图1所示的光源系统中的波长转换装置及滤光装置的主视图。如图1所示，本实施例的光源系统100主要包括激发光光源101、二向色镜（dichroic mirror）102和反射镜104、透镜103和105、波长转换装置106、滤光装置107、驱动装置108以及匀光装置109。
激发光光源101用于产生一激发光。在本实施例中，激发光光源101为一紫外或近紫外激光器或者紫外或近紫外发光二极管，以产生紫外或近紫外激发光。
如图2所示，波长转换装置106为一环状结构，包括至少一波长转换区。在本实施例中，波长转换装置106包括绕其环状结构的周向分段设置的红光转换区、绿光转换区、蓝光转换区以及黄光转换区。上述波长转换区上分别设置有不同的波长转换材料（例如荧光材料或纳米材料）。上述波长转换材料能够将入射到其上的紫外或近紫外激发光波长转换成相应颜色的受激光。具体来说，红光转换区将入射到其上的紫外或近紫外激发光转换成红光受激光，绿光转换区将入射到其上的紫外或近紫外激发光转换成绿光受激光，蓝光转换区将入射到其上的紫外或近紫外激发光转换成蓝光受激光，而黄光转换区则将入射到其上的紫外或近紫外激发光转换成黄光受激光。在本实施例中，在上述波长转换材料下方进一步设置反射衬底，进而反射上述波长转换材料所转换的受激光，使得受激光从上述波长转换区的出射方向与激发光相对上述波长转换区的入射方向相反。
如图2所示，滤光装置107为一环状结构，其与波长转换装置106同轴固定，且具体设置于波长转换装置106的环外侧。在其他实施例中，滤光装置107也可以设置于波长转换装置106的环内侧。滤光装置107包括至少一滤光区。在本实施例中，滤光装置107包括绕其环状结构的周向分段设置的红光滤光区、绿光滤光区、蓝光滤光区以及黄光滤光区。上述滤光区与波长转换装置106上的各颜色的波长转换区对应设置。
其中相同颜色的波长转换区和滤光区相对波长转换装置106和滤光装置107的环状结构的中心成0至360度设置，比如0至180度，包括或不包括端点值，如180度至360度，包括或者不包括端点值。
如图2所示，相同颜色的波长转换区和滤光区相对波长转换装置106和滤光装置107的环状结构的中心成180度设置。上述滤光区具有不同的滤光范围，进而对相应颜色的受激光进行滤光，以提高受激光的色纯度。
当然，相同颜色的波长转换区和滤光区相对波长转换装置106和滤光装置107的环状结构的中心也可以成0至360度之间的其他任意角度设置，在此不做限定。
如图1所示，驱动装置108为具有一转动轴1081的转动装置，例如转动马达。波长转换装置106与滤光装置107同轴固定于转动轴1081上，并在转动轴1081的驱动下同步转动。
在图1所示的光源系统100的工作过程中，激发光光源101所产生的紫外或近紫外激发光经二向色镜 102透射，经透镜103进行聚光后入射到波长转换装置106上，并在波长转换装置106上形成如图2所示的光斑101A。波长转换装置106和滤光装置107在驱动装置108的驱动下同步转动，进而使得波长转换装置106上的各波长转换区与滤光装置107上的各滤光区同步转动。在波长转换装置106和滤光装置107的转动过程中，波长转换装置106上的各波长转换区依次且周期性设置于激发光光源101所产生的紫外或近紫外激发光的传播路径上，使得紫外或近紫外激发光在各波长转换区的作用下依次转换成不同颜色的受激光。不同颜色的受激光进一步被上述各波长转换区反射，并经透镜103和105以及二向色镜 102和反射镜104所组成的第一光学组件导引后入射到滤光装置107，形成如图2所示的光斑101B。
在第一光学组件中，透镜103和105分别用于对受激光进行收集和聚光，以减小受激光的发散角。二向色镜 102和反射镜104则用于反射受激光，以改变受激光的传播方向。在本实施例中，二向色镜 102和反射镜104相互呈90度设置，且相对受激光的入射方向的光轴呈45度设置。
在本实施例中，请参阅图2，在二向色镜 102和反射镜104的反射作用下，受激光的传播方向被平移预定距离且反转180度，且光斑101A与光斑101B相对波长转换装置106和滤光装置107的环状结构的中心呈180度设置。
此时，由于波长转换装置106与滤光装置107相对固定，并且波长转换装置106与滤光装置107上的相同颜色的波长转换区与滤光区同样相对波长转换装置106与滤光装置107的环状结构的中心呈180度设置且同步转动，因此可以确保由波长转换装置106的各波长转换区产生的不同颜色的受激光经二向色镜 102和反射镜104作用后入射到滤光装置107上的相同颜色的滤光区上，进而由相同颜色的滤光区进行滤光来提高色纯度。经滤光装置107的滤光区过滤后的受激光进一步入射到匀光装置109，以进行匀光处理。在本实施例的光源系统100中，波长转换装置106和滤光装置107相对固定并由同一驱动装置同步驱动，同时利用第一光学组件将相同颜色的波长转换区与滤光区进行同步，具有结构简单、易于实现以及同步性高等优点。此外，第一光学组件的各元件相对激发光光源保持静止，避免了随波长转换装置106和滤光装置107转动，因此其光学稳定性更高。
进一步，由于通过波长转换产生的受激光一般是近似朗伯分布，如果该受激光直接入射到滤光区上，则其入射角从0度到90度都存在。然而，滤光区的穿透率随着入射角的增大而飘移，因此在本实施例的第一光学组件中进一步设置聚光装置（例如，透镜105）对受激光进行聚光，使得受激光入射到滤光区的入射角较小，进一步提高了滤光效果。在优选实施例中，通过调整第一光学组件，可使得受激光的入射到滤光装置107的入射角小于等于60度范围内的能量占总能量的90%以上。在本实施例中，二向色镜 102和反射镜104可以由其他形式的平面反射装置代替，而透镜103和105则可以由其他形式的光学装置所代替。例如，透镜105可以是实心或者空心的锥形导光棒、透镜或者透镜组、空心或者实心的复合型聚光器或者曲面反射镜等各种形式的聚光装置。
此外，在本实施例中，波长转换装置106上的波长转换区可以是红光转换区、绿光转换区、蓝光转换区以及黄光转换区中的一个或多个的任意组合，并选择其他适当的光源作为激发光光源。或者，本领域技术人员可以根据需要设置其他颜色的波长转换区以及激发光光源。此时，滤光装置107上的滤光区则根据波长转换装置106上的波长转换区所产生的受激光的颜色进行相应配置，本实用新型对此并不作限制。
请参见图3和图4，图3是本实用新型光源系统的第二实施例的结构示意图，图4是图3所示的光源系统中的波长转换装置及滤光装置的主视图。如图3所示，本实施例的光源系统主要包括激发光光源1301、二向色镜（dichroic mirror）1302和反射镜1304、透镜1303和1305、波长转换装置1306、滤光装置1307、驱动装置1308以及匀光装置1309。本实施例与上述第一实施例之间的区别在于，本实施例中，相同颜色的波长转换区和滤光区相对波长转换装置1306和滤光装置1307的环状结构的中心成0度设置，如图4所示。
在本实施例中，当相同颜色的波长转换区和滤光区相对波长转换装置106和滤光装置107的环状结构的中心成α角度设置时，相对于图4所示的相同颜色的波长转换区和滤光区相对波长转换装置106和滤光装置107的环状结构的中心成0角度设置来说，需要在图3所示的光源结构的基础上，对第一光学组件进行调整，即保持第一光学组件包括的各部件之间的相对位置不变，将图3所示的第一光学组件以从激发光光源出射至波长转换装置1306的激发光的光轴为旋转轴，绕激发光的光轴旋转α角度，其余部件不改变。
如当相同颜色的波长转换区和滤光区相对波长转换装置106和滤光装置107的环状结构的中心成如图2所示的180度设置时，则该光源系统为在图3所示的光源系统的基础上，保持第一光学组件包括的各部件之间的相对位置不变，将图3所示的第一光学组件以从激发光光源出射至波长转换装置的激发光的光轴为旋转轴，沿激发光的光轴旋转180度，从而变成图1所示的光源系统。
如图5所示，相同颜色的波长转换区和滤光区相对波长转换装置106和滤光装置107的环状结构的中心成45度设置。则在图3所示的基础上，将第一光学组件以从激发光光源出射至波长转换装置的激发光的光轴为旋转轴，沿激发光的光轴旋转45度。
如图6所示，相同颜色的波长转换区和滤光区相对波长转换装置106和滤光装置107的环状结构的中心成90度设置。则在图3所示的基础上，将第一光学组件以从激发光光源出射至波长转换装置的激发光的光轴为旋转轴，沿激发光的光轴旋转90度。
如图7所示，相同颜色的波长转换区和滤光区相对波长转换装置106和滤光装置107的环状结构的中心成120度设置。则在图3所示的基础上，将第一光学组件以从激发光光源出射至波长转换装置的激发光的光轴为旋转轴，沿激发光的光轴旋转120度。
如图8所示，相同颜色的波长转换区和滤光区相对波长转换装置106和滤光装置107的环状结构的中心成225度设置。则在图3所示的基础上，将第一光学组件以从激发光光源出射至波长转换装置的激发光的光轴为旋转轴，沿激发光的光轴旋转225度。请参见图9和图10，图9是本实用新型光源系统的第二实施例的结构示意图，图10是图9所示的光源系统中的波长转换装置及滤光装置的主视图，其以波长转换装置206与滤光装置207上的相同颜色的波长转换区与滤光区同样相对波长转换装置206与滤光装置207的环状结构的中心呈180度设置为例，可以理解，波长转换装置206与滤光装置207上的相同颜色的波长转换区与滤光区同样相对波长转换装置206与滤光装置207的环状结构的中心可以成0至180度之间的任意角度。本实施例的光源系统200与图1和图2所示的光源系统100不同之处在于，激发光光源201为一蓝光激光器或蓝光发光二极管，以产生蓝光激发光。如图10所示，在本实施例中，波长转换装置206除了包括红光转换区、黄光转换区以及绿光转换区外，进一步包括一蓝光透光区。滤光装置207则包括红光滤光区、黄光滤光区以及绿光滤光区。在本实施例中，对滤光装置207的与波长转换装置206的蓝光透光区对应的区域不做光学要求，但是为了转动的平衡，可以设置成配重平衡区，进而与其他滤光区保持相同或相似的重量。在本实施例中，在驱动装置208的驱动下，波长转换装置206与滤光装置207同步转动，使得波长转换装置206上的各波长转换区和蓝光透光区依次且周期性设置于激发光光源201所产生的蓝光激发光的传播路径上。其中，各波长转换区将入射到其上的蓝光激发光转换成对应颜色的受激光并进行反射，而蓝光透光区则透射入射到其上的蓝光激发光。蓝光透光区上可设置适当的散射机构，以破坏蓝光激发光的准直性。经波长转换装置206反射后的受激光经透镜203和205以及二向色镜 202和反射镜204所组成的第一光学组件导引后入射到滤光装置207上的相应颜色的滤光区，由该滤光区进行滤光来提高色纯度。经波长转换装置206透射的蓝光激发光在透镜210和213、反射镜211以及二向色镜 212所组成第二光学组件的导引下与经滤光装置207过滤后的受激光进行光路合并，并共同入射到匀光装置209，以进行匀光处理。
第二光学组件中，透镜210和213分别用于对经波长转换装置206透射的蓝光激发光进行收集和聚光，而反射镜211和二向色镜 212则用于对经波长转换装置206透射的蓝光激发光进行反射，以改变其传播路径。在本实施例中，反射镜211和二向色镜 212相互并行设置，且相对蓝光激发光的入射方向呈45度设置，以使得蓝光激发光的传播方向被平移预定距离且方向保持不变。
在本实施例中，通过透射方式将激发光光源201产生的蓝光激发光直接作为蓝光输出。在本实施例中，反射镜211和二向色镜 212同样可以由其他形式的平面反射装置代替，而透镜210和213则可以由其他形式的光学装置所代替。此外，上述结构同样适用于采用其他颜色的激发光光源的光源系统中。
请参见图11和图12，图11是本实用新型光源系统的第三实施例的结构示意图，图12是图11所示的光源系统中的波长转换装置及滤光装置的主视图，其以波长转换装置206与滤光装置207上的相同颜色的波长转换区与滤光区同样相对波长转换装置306与滤光装置307的环状结构的中心呈180度设置为例，可以理解，波长转换装置306与滤光装置307上的相同颜色的波长转换区与滤光区同样相对波长转换装置306与滤光装置307的环状结构的中心可以成0至180度之间的任意角度。本实施例的光源系统300与图9和图10所示的光源系统200不同之处在于，光源系统300在激发光光源301的基础上进一步包括一红光照明光源315（例如，红光激光器或红光发光二极管），以产生一红光照明光。红光照明光源315与激发光光源301分别设置于波长转换装置306与滤光装置307的相对两侧。红光照明光源315产生的红光照明光经透镜314、二向色镜311以及透镜310入射到波长转换装置306，并且其入射方向与激发光光源301产生的激发光的入射方向相反。
在本实施例中，波长转换装置306包括红光透光区、黄光转换区、绿光转换区以及蓝光透光区。滤光装置307则包括红光透光区、黄光滤光区、绿光滤光区以及配重平衡区。在本实施例中，在驱动装置308的驱动下，波长转换装置306与滤光装置307同步转动，使得波长转换装置306上的各波长转换区、红光透光区以及蓝光透光区依次且周期性设置于激发光光源301所产生的蓝光激发光以及红光照明光源315所产生的红光照明光的传播路径上。其中，各波长转换区将入射到其上的蓝光激发光转换成对应颜色的受激光并进行反射，蓝光透光区透射入射到其上的蓝光激发光，红光透光区则透射入射到其上的红光照明光。蓝光透光区和红光透光区上可设置适当的散射机构，以破坏蓝光激发光和红光照明光的准直性。经波长转换装置306反射后的受激光经透镜303和305以及二向色镜 302和反射镜304所组成的第一光学组件导引后入射到滤光装置307上的相应颜色的滤光区，由该滤光区进行滤光来提高色纯度。经波长转换装置306透射的红光照明光经透镜303和305以及二向色镜 302和反射镜304所组成的第一光学组件导引沿与受激光相同的光路入射滤光装置307上的红光透光区，并经红光透光区透射。经波长转换装置306透射的蓝光激发光在透镜310和313以及二向色镜 311和312所组成的第二光学组件的导引下与经滤光装置307过滤后的受激光以及经滤光装置307透射后的红色照明光进行光路合并，并共同入射到匀光装置309，以进行匀光处理。
在一优选实施例中，为了确保匀光装置309在某一特定时刻仅接收到一种颜色的光，对波长转换装置306的转动位置进行探测，并产生同步信号。激发光光源301和红光照明光源315根据该同步信号采用分时开启方式工作。具体来说，红光照明光源315仅在红光透光区设置于红光照明光源315产生的红光照明光的传播路径上时才开启，而在黄光转换区、绿光转换区以及蓝光透光区设置于红光照明光的传播路径上时关闭。激发光光源301则是在黄光转换区、绿光转换区以及蓝光透光区设置于激发光光源301产生的蓝光激发光的传播路径上时才开启，而在红光透光区设置于蓝光激发光的传播路径上时关闭。此外，在另一优选实施例中，也可以在红光透光区设置透射红光照明光且反射蓝光激发光的分光滤光片，在黄光转换区和绿光转换区的靠近红光照明光源315的一侧设置反射红光照明光的反射镜，而在蓝光透光区设置透射蓝光激发光且反射红光照明光的分光滤光片。
在本实施例中，光源系统300输出的红光直接由红光照明光源315产生，进而避免了红光转换材料的转换效率低的问题。当然，在需要进一步提高色纯度的情况下，可以将上述红光透光区替换成红光滤光区。在本实施例中，本领域技术人员完全可以想到利用其他照明光源来产生其他颜色的照明光。
请参见图13，图13是本实用新型光源系统的第四实施例的结构示意图。本实施例的光源系统400与图11和图13所示的光源系统300不同之处在于，本实施例的激发光光源401采用紫外或者蓝光激发光源。同时，本实施例的波长转换装置406上设置黄光转换区、绿光转换区和红光透光区。因此，激发光光源401仅用于激发黄光转换区和绿光转换区来产生黄光受激光和绿光受激光。本实施例的光源系统400在激发光光源401和红光照明光源415的基础上进一步设置一蓝光照明光源416。该蓝光照明光源416所产生的蓝光照明光经由透镜417和418以及二向色镜419所组成的第二光学组件与经滤光装置407过滤后的受激光以及经滤光装置407透射或过滤后的红色照明光进行光路合并，并共同入射到匀光装置409，以进行匀光处理。在本实施例中，激发光光源401、红光照明光源415、蓝光照明光源416同样可采用与第三实施例类似的分时开启方式工作。
在本实施例中，光源系统300输出的红光直接由红光照明光源415产生，光源系统300输出的蓝光直接由蓝光照明光源416产生，进而避免了波长转换材料的转换效率低的问题，同时更适于显示领域。
请参见图14，图14是本实用新型光源系统的第五实施例的结构示意图。本实施例的光源系统500与图1和图2所示的光源系统100不同之处在于，波长转换装置506在将激发光光源501产生的激发光波长转换成受激光后透射该受激光。经波长转换装置506透射的受激光经透镜503和505以及反射镜502以及504所组成的第一光学组件导引后入射到滤光装置507的相同颜色的滤光区，并经该滤光区进行过滤后入射到匀光装置509。
此外，激发光光源501也可以为蓝光光源，在波长转换装置506还可以进一步设置一透光区，该透光区周期性设置于激发光光源501产生的激发光的传播路径上，并透射该激发光。经该透光区透射的激发光经透镜503和505以及反射镜502以及504所组成的第一光学组件沿着与受激光相同的光路导引到滤光装置507上的另一透光区或滤光区，进行透射或过滤。
请参见图15，图15是本实用新型光源系统的第六实施例的结构示意图。本实施例的光源系统600与图14所示的光源系统500不同之处在于，本实施例的光源系统600在激发光光源601的基础上进一步设置红光照明光源615，以产生一红光照明光。红光照明光源615与激发光光源601设置于波长转换装置606与滤光装置607的同侧。红光照明光源615产生的红光照明光经二向色镜 613反射并经透镜611聚光后与激发光光源601产生的激发光沿相同方向入射到波长转换装置606。其中，激发光光源601产生的激发光经波长转换装置606上的波长转换区波长转换成受激光，并经波长转换装置606透射。红光照明光源615产生的红光照明光则经波长转换装置606上的红光透光区直接透射。经波长转换装置606透射后的受激光以及红光照明光在反射镜602和604以及透镜603和605所组成的第一光学组件的导引下沿相同的光路分别入射到滤光装置607的滤光区和红光透光区。经滤光区过滤的受激光和经红光透光区透射的红光照明光进一步入射到匀光装置609。此外，上述红光透光区也可以由红光滤光区所代替。此外，本实施例中的激发光光源601与红光照明光源615同样可采用与第三实施例类似的分时开启方式进行工作。
请参见图16，图16是本实用新型光源系统的第七实施例的结构示意图。本实施例的光源系统700与图15所示的光源系统600不同之处在于，本实施例的光源系统700在激光光光源701和红光照明光源715的基础上进一步设置一蓝光照明光源716。该蓝光照明光源716所产生的蓝光照明光经透镜717以及二向色镜 718所组成的第二光学组件与经滤光装置707过滤后的受激光以及经滤光装置707过滤或透射后的红色照明光进行光路合并，并共同入射到匀光装置709，以进行匀光处理。本实施例中的激发光光源701、红光照明光源715以及蓝光照明光源716同样可采用与第三实施例类似的分时开启方式进行工作。
请参见图17，图17是本实用新型光源系统的第八实施例的结构示意图。本实施例的光源系统800与图1和图2所示的光源系统100不同之处在于，本实施例的激发光光源801产生的激发光由复眼透镜803和804以及聚焦透镜805进行聚光后经反射装置802的入光口入射到波长转换装置806。经波长转换装置806反射的受激光经呈半椭球状或者呈半球状且光反射面朝内的反射装置802反射到滤光装置807。经滤光装置807过滤的受激光进一步入射到锥形导光棒809。其中，当反射装置802呈半椭球状时，反射装置802能够将来自反射装置802的一个焦点附近的受激光反射到反射装置802的另一个焦点附近。当反射装置802呈半球状时，在临近球心的位置设置关于该球心对称的两对称点，反射装置802大致也可以把其中一对称点的受激光反射到另一对称点。此外，在其他实施例中，反射装置802可以不设置入光口，此时激发光光源801与反射装置802分别设置于波长转换装置806的两侧。激发光光源801产生的激发光可照射到波长转换装置806后所产生的受激光进一步透射到反射装置802上。
值得注意的是，在反射装置802的反射作用下，激光光光源801所产生的激发光在波长转换装置806上产生的光斑与受激光在滤光装置807上产生的光斑相对于波长转换装置806和滤光装置807的环状结构的中心呈0度设置，因此在波长转换装置806和滤光装置807上相同颜色的波长转换区和滤光区也需要相对于波长转换装置806和滤光装置807的环状结构的中心呈0度设置。
当然，在其他实施例中，通过适当的光学机构，可以调整激发光在波长转换装置806上产生的光斑与受激光在滤光装置807上产生的光斑相对波长转换装置806和滤光装置807的环状结构的中心呈任意角度设置，因此使得波长转换装置806和滤光装置807上的相同颜色的波长转换区和滤光区相对于波长转换装置806和滤光装置807的环状结构的中心呈任意角度设置。
请参见图18，图18是本实用新型光源系统的第九实施例的结构示意图。本实施例的光源系统900与图17所示的光源系统800不同之处在于，波长转换装置906与滤光装置907由支架908同轴固定，且沿轴向间隔设置。在波长转换装置906与滤光装置907之间设置一锥形导光棒909。激发光光源901产生的激发光由复眼透镜903和904以及聚焦透镜905进行聚光后经反射装置902的入光口入射到波长转换装置906。经波长转换装置906反射的受激光入射到反射装置902并进行反射。经反射装置902反射的受激光首先进入导光棒909。导光棒909对受激光进行收集，以减小受激光的发散角。经导光棒909导光后的受激光入射到滤光装置907上，使得受激光在滤光装置907上的入射角度较小，提高了滤光效果。在本实施例中，导光棒909也可以由其他能够实现上述功能的光学装置代替。此外，在本实施例中，波长转换装置906如果是透射型，反射装置902可以省略，此时受激光直接经波长转换装置906透射到导光棒909。
如上文所描述的，在图17和图18所示的实施例中，可以在激发光光源801和901的基础上进一步增加照明光源，例如红光照明光源或蓝光照明光源。
请参见图19，图19是本实用新型光源系统的第十实施例的结构示意图。本实施例的光源系统1000与图1和图2所示的光源系统100不同之处在于，本实施例的波长转换装置1006呈筒状结构，波长转换区设置于该筒状结构的外侧壁上。本实施例的滤光装置1007为环状结构且该筒状结构同轴固定。波长转换装置1006和滤光装置1007进一步同轴固定于驱动装置1008的转动轴上，并在驱动装置1008的驱动下同轴且同步转动。
在本实施例的光源系统1000的工作过程中，激发光光源1001所产生的激发光经二向色镜 1002透射，并经透镜1003进行聚光后入射到波长转换装置1006的外侧壁上。波长转换装置1006的外侧壁上的波长转换区将激发光转换成受激光，并反射该受激光。经波长转换装置1006反射的受激光经透镜1003和1004以及二向色镜 1002所组成的第一光学组件导引后入射到滤光装置1007。滤光装置1007上的滤光区设置于波长转换装置1006的筒状结构的外侧，进而可以接收到受激光并对受激光进行滤光来提高色纯度。经滤光装置1007的滤光区过滤后的受激光进一步入射到匀光装置1009，以进行匀光处理。在其他实施例中，波长转换装置1006也可以将受激光透射到滤光装置1007上。
请参见图20，图20是本实用新型光源系统的第十一实施例的结构示意图。本实施例的光源系统1100与图1和图2所示的光源系统100不同之处在于，本实施例的波长转换装置1106和滤光装置1107为同轴固定且相互嵌套的两个筒状结构，波长转换区和第一滤光区分别设置于该两个筒状结构的侧壁上。其中，滤光装置1107位于波长转换装置1106的外侧。波长转换装置1106和滤光装置1107进一步同轴固定于驱动装置1108的转动轴上，并在驱动装置1108的驱动下同轴且同步转动。
在本实施例的光源系统1100的工作过程中，激发光光源1101所产生的激发光经反射镜1102反射，并经透镜1103进行聚光后入射到波长转换装置1106上。波长转换装置1106上的波长转换区将激发光转换成受激光，并透射该受激光。经波长转换装置1106透射的受激光经透镜1104所组成的第一光学组件导引后入射到滤光装置1107。滤光装置1107上的滤光区对受激光进行滤光来提高色纯度。经滤光装置1107的滤光区过滤后的受激光进一步入射到匀光装置1109，以进行匀光处理。
请参见图21和图22，图22是本实用新型光源系统的第十二实施例的结构示意图，图22是图21所示的光源系统中的波长转换装置与滤光装置的主视图。本实施例的光源系统1200与图9和图10所示的光源系统200不同之处在于，本实施例的波长转换装置1206和滤光装置1207为首尾相连的两个带状结构，波长转换区和第一滤光区并排设置于该两个带状结构上。在本实施例中，波长转换装置1206进一步包括并排且从上到下依序设置的红光转换区、绿光转换区、蓝光透光区以及黄光转换区，滤光装置1207则包括并排且从上到下依序设置的红光滤光区、绿光滤光区、空置区以及黄光滤光区。
在波长转换装置1206和滤光装置1207在适当的驱动装置（例如，线形马达）的驱动下进行往复的线性平移，以使得波长转换装置1206上的红光转换区、绿光转换区、蓝光透光区以及黄光转换区周期性设置于激发光光源1201所产生的蓝光激发光的传播路径上。其中，各波长转换区将入射到其上的蓝光激发光转换成对应颜色的受激光并进行反射，而蓝光透光区则透射入射到其上的蓝光激发光。蓝光透光区上可设置适当的散射机构，以破坏蓝光激发光的准直性。经波长转换装置1206反射后的受激光经透镜1203和1205、二向色镜 1202以及反射镜1204所组成的第一光学组件导引后入射到滤光装置1207上的相应颜色的滤光区，由该滤光区进行滤光来提高色纯度。经波长转换装置1206透射的蓝光激发光在透镜1210和1213、反射镜1211和二向色镜1212所组成第二光学组件的导引下与经滤光装置1207过滤后的受激光进行光路合并，并共同入射到匀光装置1209，以进行匀光处理。本实施例的波长转换装置1206和滤光装置1207的结构同样可以应用于上文描述的其他实施例中，在此不再赘述。
本实用新型进一步提供一种由上述实施例中的波长转换装置以及滤光装置所构成的光源组件。
综上所述，本实用新型的光源系统及光源组件中的滤光装置与波长转换装置相对固定，并由同一驱动装置进行驱动，具有结构简单、易于实现以及同步性高等优点。
