本发明将第一光分光成第一范围波长光和第二范围波长光，并且该两 个范围波长光与第二光的至少部分光时序出射，这样， 某个时段只出射两 束光束， 另一时段只出射一束光束， 以使得可以采用两个空间光调制器对 三个光束进行调制；并且本发明可以采用具有较高光转换效率的波长转换 材料产生的受激光分光成另两个具有较低光转换效率的波长转换材料的 颜色光， 以提高光源的效率。 附图说明

本发明的发明思路包括： 通过发光装置依序出射第一光与第二光，通 过分光系统将第一光分成沿不同路径传播的两束不同波长范围光， 这样， 在某一时段分别出射两个不同波长范围光至两个空间光调制器，另一时段 出射第二光的至少部分光至这两个空间光调制器中的一个，以使得能用两 个空间光调制器对三束不同光进行调制； 同时，还可以通过将具有较高的 光转换效率的黄光荧光粉受激发产生的黄色受激光分光成红光和绿光，从 而避免使用光转换效率较低的红光荧光粉产生红光，以提高光源系统的效 率。
如图 1所示， 图 1是黄色荧光粉产生的黄光光谱的一个具体例子。 由 图可看出， 荧光粉产生的黄光的光语较宽，覆盖了绿光的光谱和红光的光 谱。 因此， 可将黄光分光成为绿光和红光。 为便于描述， 下文所提到的黄 光的光谱均覆盖红光成分以及绿光成分，黄光可经滤光装置分光成沿不同 路径传播的红光和绿光。
下面结合附图和实施方式对本发明实施例进行详细说明。
实施例一
请参阅图 2 , 图 2是本发明的光源系统的一个实施例的示意图。 该实 施例的光源系统 200包括发光装置 1、分光系统 2、第一空间光调制器 211 和第二空间光调制器 213。
发光装置 1包括用于产生激发光的激发光源 201、 波长转换层 203与 第一驱动装置 205。 波长转换层 203包括第一分区和第二分区， 该第一分 区上设置有第一波长转换材料，用于吸收激发光并出射第一光； 该第二分 区上设置有透光区，用于透射激发光，该激发光为第二光。在本实施例中， 激发光源 201用于产生蓝色激发光。激发光源 201优选为激光光源，也可 以为 LED或者其他固态光源。 波长转换层 203上的第一分区上设置有黄 光荧光粉， 用于吸收激发光并产生黄色受激光， 此为第一光； 第二分区上 为透光区， 用于透射蓝光， 此为第二光。 波长转换层 203呈圓盘状， 波长 转换层上的不同分区沿着该该圓盘周向分布。
第一驱动装置 205用于驱动波长转换层 203 ,使得激发光在波长转换 层 203上形成的光斑按预定路径作用于波长转换层 203 , 以使该激发光依 序照射在第一分区与第二分区上， 以使第一光和第二光依序出射。在本实 施例中，第一驱动装置 205为马达，用于驱动波长转换层 203周期性转动。
分光系统 2用于将来自发光装置 1的第一光分成沿第一光通道和第二 光通道出射的第一范围波长光和第二范围波长光；还用于将来自发光装置 1的第二光的至少部分光沿第一光通道出射。 第一空间光调制器 211用于 对分光系统 2 沿第一光通道出射的光进行调制。 第二空间光调制器 213 用于对分光系统 2沿第二光通道出射的至少部分光进行调制。经第一空间 光调制器 211和第二空间光调制器 213调制的光进行合光并进入投影区 域。
在本实施例中， 分光系统 2将黄光分光成绿光， 即第一范围波长光， 和红光， 即第二范围波长光。 为描述清楚， 在以下举例中， 第一光黄光分 光成绿光和红光时，其中第一范围波长光和第二范围波长光不一定分别是 绿光和红光，该两种范围光只是个相对概念，第一范围波长光和第二范围 波长光也可以分别是红光和绿光。
第一空间光调制器 211用于对时序的蓝光和绿光进行调制，第二空间 光调制器 213用于对红光进行调制。 由于黄光荧光粉的转换效率较高， 而 蓝光直接由发光器件产生，因此用蓝光激发黄光荧光粉而产生三基色使得 光源的效率较高。
具体举例来说， 分光系统 2包括 TIR ( Total Internal Reflection, 全内 反射）棱镜 207和 209的组合。 该两个棱镜为三角柱体， 其中第一棱镜 207的侧面为 207a、 207b和 207c, 第二棱镜 209的侧面为 209a、 209b和 209c； 其中第一棱镜 207的侧面 207c和第二棱镜 209的侧面 209c相接。
波长转换层 203出射的受激光 23从第一棱镜 207的侧面 207b进入该 棱镜， 并在侧面 207a上发生全反射， 经侧面 207c透射后从第二棱镜 209 的侧面 209c透射进入第二棱镜 209并到达侧面 209a上。 侧面 209a为镀 膜面， 其上镀有滤光膜， 该滤光膜透射红光， 并反射蓝光和绿光。 时序产 生的蓝光和绿光经镀膜面 209a反射后又在侧面 209c上发生全反射，并在 侧面 209b上透射以从第一光通道进入第一空间光调制器 211。 经调制后 的蓝光和绿光以另一角度入射侧面 209b并透射，并在侧面 209c上发生全 反射，然后经镀膜面 209a反射后从侧面 209c透射并从第一棱镜 207透射 出去。 而红光经镀膜面 209a透射后从第二光通道进入第二空间光调制器 213。 经调制后的红光依次从第二棱镜 209和第一棱镜 207透射， 与被调 制后的绿光合为一束光束。
空间光调制器可以是 DMD, 也可以是液晶等其他类型的空间光调制 器。 为方便说明， 在以下实施例中均采用 DMD作为例子。
如图 3A所示， 图 3A是波长转换层 203出射光的时序图的一种实施 例。 在本实施例中， 波长转换层 203上的第一分区占 270度， 第二分区占 90度。 从波长转换层 203的第二分区开始进入激发光的入射光路开始， 在波长转换层 203转动的一周期 T时间内， 光源系统的工作过程如下。 在前 0.25T内，波长转换层 203出射蓝光，在后 0.75T内，波长转换层 203 出射黄光。 相对应地， 前 0.25T内 DMD 211用于调制蓝光， DMD 213未 用于调制光束。 后 0.75T内 DMD 211用于调制绿光， DMD 213用于调制 红光。如图 3B和图 3C所示，图 3B和图 3C分别为 DMD 211和 DMD 213 对不同色光的调制时间图的一种实施例。 在这种情况下， 每一个周期 T 内红光和绿光均全被利用， 使得光源的利用最高效。 然而， 这可能不是实 际情况，因为这可能引起该三基色光混合而成的白光的色坐标与预定色坐 标有偏差。 在实际运用中， 可以通过利用该两个 DMD对不同颜色光的调 制时间的长短来控制白光的色坐标使之达到满意。 例如， 在本实施例中， 如果红光过多而导致白光的色坐标偏红， 则可以控制 DMD 213的调制时 间变短，使得在一定时间段上的红光为无效光。如图 4所示，图 4是 DMD 213对红光的调制时间图的又一种实施例。 在图 4中， 每一个周期 T内红 光的后段部分被舍弃。 在实际运用中， 也可以将红光的前段舍弃， 或者中 间的一端或几段舍弃， 这都是容易理解的。
另外， 以上第一分区和第二分区所占的比例只是举例， 并未限制其实 际比例。在实际运用中，可根据实际需要来决定第一分区和第二分区的所 占比例。
在本实施例中，发光装置依序出射第一光与第二光，并通过分光系统 将第一光分成沿不同路径传播的两束不同波长范围光，这样，在某一时段 分别出射两个不同波长范围光至两个空间光调制器，另一时段出射第二光 的至少部分光至这两个空间光调制器中的一个，以使得能用两个空间光调 制器对三束不同光进行调制。
在实际运用中， 分光系统 2中的 TIR棱镜 209中的镀膜面 209a上的 滤光曲线也可以是透射绿光和蓝光，并反射红光，在这种情况中， DMD 211 用于调制红光， DMD 213用于调制绿光和蓝光； 或者镀膜面 209a上的滤 光曲线改为透射绿光， 并反射红光和蓝光； 则 DMD 211用于调制红光和 蓝光， DMD 213用于调制绿光。 实际运用中可根据实际需要来设计镀膜 面 209a的滤光曲线。
以上受激光在该两块 TIR棱镜中的光路仅为方便说明而列举的例子， 并不限制 TIR棱镜的其他用法。
在上面的实施例中，使用两块棱镜来同时实现黄光中绿光成分和红光 成分的分光以及经两个空间光调制器调制后的光束的合光。 在实际运用 中， 也可以使用分光滤光片来对黄光进行分光， 并在两个 DMD的光路后 端使用滤光片来对其调制后的光束进行合光。
实施例二
如图 5所示， 图 5是本发明的光源系统的又一个实施例的示意图。本 实施例中， 光源系统 500包括发光装置 1、 分光系统 2、 第一空间光调制 器 511与第二空间光调制器 513。 发光装置 1包括激发光源 501、 波长转 换层 503与第一驱动装置 505。
本实施例与图 2所示实施例的区别之处包括：
分光系统 2包括滤光片 509与反射镜 507。 滤光片 509用于接收波长 转换层 503依序出射的黄光 53和蓝光 55 , 并透射蓝光 55和黄光 53中的 绿光 53a从第一光通道出射至 DMD511 , 且反射黄光 53中的红光 53b至 反射镜 507, 反射镜 507反射红光 53b从第二光通道出射至 DMD513。
优选地， 光源系统 500还包括分别设置于 DMD511与 DMD513的出 射光路上的滤光片 515与反射镜 517。反射镜 517用于将经 DMD511调制 后的时序的蓝光和绿光反射至滤光片 515。 滤光片 515用于反射来自反射 镜 517的蓝光和绿光并透射来自 DMD513的红光，以将 DMD 511和 DMD 513调制出射的光束合为一束光。 可以理解的是， 在其它实施例中， 可以 通过设置 DMD 511与 DMD 513的出光角度， 使得 DMD511与 DMD513 分别出射的两束光汇聚为一束光； 此外， 在有些应用场合中， 也可以不需 要将 DMD511与 DMD513分别出射的两束光汇聚为一束光， 因此反射镜 517与滤光片 515是可以省略的。
实施例三
请参阅图 6, 图 6是本发明的光源系统的又一个实施例的示意图。 本 实施例中， 光源系统 600包括发光装置 1、 分光系统 2、 第一空间光调制 器 611与第二空间光调制器 613。 发光装置 1包括激发光源 601、 波长转 换层 603与第一驱动装置 605。
本实施例与图 5所示实施例的区别之处包括：
分光系统 2包括第一分光装置 609、第二驱动装置 607和第一控制装 置 （图未示）。 为提高发光装置 1的出射光的利用率， 光源系统 600还包 括设置于发光装置 1与分光系统 2之间的光路上的收集透镜 615 , 用于收 集发光装置依序出射的黄光 63和蓝光 65 , 并将收集的光中继至第一分光 装置 609。 第一分光装置 609呈圓盘状， 并沿周向分为第一区段和第二区 段。第二驱动装置 607用于驱动第一分光装置转动，使得第一区段和第二 区段依序处于发光装置 1的出射光路上。第一控制装置控制第一驱动装置 605与第二驱动装置 607的转动 ,使得第一分光装置 609与波长转换层 603 同步转动， 以使第一区段位于第一光， 即黄光 63的出射光路上， 第二区 段位于第二光， 即蓝光 65的出射光路上。
第一分光装置 609上的第一区段用于透射黄光 63中的绿光从第二光
611 , 第二区段用于反射蓝光 65从第一光通道出射至 DMD 611。 当然， 在实际运用中也可以使第一区段反射红光并透射绿光； 或者， 第二区段也 可以透射部分蓝光并反射部分蓝光，其中该透射和反射的这两束蓝光可以 分别被 DMD 611与 DMD 613调制， 也可以只调制这两束中的其中一束。
实施例四
请参阅图 7, 图 7是本发明的光源系统的又一个实施例的示意图。 在本实施例中， 光源系统 700包括发光装置 1、 分光系统 2、 第一空间光 调制器 711与第二空间光调制器 713。 发光装置 1包括激发光源 701、 波 长转换层 703B与第一驱动装置 705。分光系统 2包括第一分光装置 703A 和光引导装置 3。 本实施例与图 6所示实施例的区别之处包括：
在本实施例中， 波长转换层 703B和第一分光装置 703A固定连接， 共同设置在色轮 703上。如图 8所示， 图 8是图 7中色轮 703的一个实施 例的主视图。 色轮 703 上设置有两个同心设置且相互嵌套的圓环区域 703 A和 703B, 其中圓环 703 A为分光区， 即第一分光装置； 圓环 703B 为波长转换区， 即波长转换层。 分光区 703A中包括第一区段 S1 , 用于透 射绿光至第一光通道出射， 并反射红光至第二光通道出射； 分光区 703A 还包括第二区段 S2 , 用于透射蓝光至第一光通道出射。 波长转换区 703B 包括第一分区 W1 , 设置有黄光波长转换材料， 用于产生黄色受激光， 该 分区与分光区 703A中第一区段 S1相对该环状的中心呈 180度设置； 还 包括第二分区 W2,设置有透光区，用于透射蓝光，该分区与分光区 703A 中的第二区段 S2相对该环状的中心呈 180度设置。 第一驱动装置 705用 于驱动色轮 703转动，使得第一分区 W1和第二分区 W2依序位于发光装 置 1的出射光路上。
光引导装置 3用于将波长转换层 703B上的第一分区 W1和第二分区 W2出射的时序光分别引导至第一分光装置 703A上的第一区段 S1和第二 区段 S2上。 具体解释如下。
在本实施例中， 光引导装置 3包括透镜 707、 反射镜 709和 715。 在 色轮 703转动的一个周期 T内， 在前 tl时间内， 激发光源 701产生的激 发光 71入射到波长转换区 703B上的第一分区 W1并出射黄光， 出射光 73从波长转换区 703B背向激发光的一侧出射，并经透镜 707收集后依次 被反射镜 709和 715反射并以 45度入射至分光区 703A上的第一区段 S1 上， 黄光中的绿光成分和红光成分分别经第一区段 S2透射和反射并分别 沿第一光通道出射至 DMD 711和沿第二光通道出射至 DMD713。
后 t2时间内， 激发光 71入射到第二分区 W2并出射蓝光， 经光引导 装置 3引导以 45度角入射至第二区段 S2上， 经透射后从第二光通道入 射至 DMD 711。激发光 71在分光区 705A上形成的光斑 A与在波长转换 区 703B上形成的光斑 B的连线经过环心 。 当然， 在实际运用中， 出射 分；
这可根据实际需要设计， 这样，相比图 6所示的光源系统， 波长转换层和第一分光装置可以同 步转动， 该两者的同步性更好， 而且不需要控制装置来控制其同步， 减小 了成本和光源体积。 实施例五
请参阅图 9, 图 9是图 6中第一分光装置 609的又一个实施例的主视 图。 与图 6 所示的光源系统不同的是， 本实施例中的第一分光装置 609 包括三个区段。 第一区段 R1用于透射红光至第一光通道出射， 并反射绿 光至第二光通道出射。 第二区段 R2用于透射绿光至第一光通道出射， 并 反射红光至第二光通道出射。第三区段用于透射部分蓝光至第一光通道出 射， 并反射部分蓝光至第二光通道出射。
相对应地， 第一控制装置用于控制第一分光装置 609, 使得第一区段 R1和第二区段 R2位于第一光的出射光路上， 第三区段 R3的位于第二光 的出射光路上。 具体来说， 在出射黄光的 T中， 前部分时间 tl 内第一区 段 R1位于黄光的出射光路上， 后部分时间 t2内第二区段 R2位于黄光的 出射光路上， 在出射蓝光时第三区段 R3位于蓝光的出射光路上。
在本实施例中，在波长转换层 603转动而产生 Y( yellow,黄）、B( blue, 蓝）序列光的一个周期内， DMD 611依次接收到 G(green, 绿)、 R ( red, 红）、 B序列光， DMD 613依次接收到 R、 G 、 B序列光。 因此， 相比以 上各实施例， 本实施例中两个 DMD能够各自接收到三基色序列光， 进而 每个 DMD可以各自调制一个图像， 并且在任何时段， 两个 DMD都处于 工作状态， 相比以上实施例能够更充分地利用 DMD。
容易理解的是，本实施例中也可以将波长转换层与第一分光装置固定 连接。相对应地， 图 7中所示的光源系统中色轮 703上的分光区上的第一 区段 S1需分成第一子区和第二子区， 其中第一子区用于透射红光至第一 光通道出射至 DMD 611 , 并反射绿光至第二光通道出射至 DMD 613; 第 二子区用于透射绿光至第一光通道出射至 DMD 613 , 并反射红光至第二 光通道出射至 DMD 611。
实施例六
图 7 所示的光源系统只是其中一种将波长转换层与第一分光装置固 定连接的结构， 在实际运用中还有许多其他光路结构。 请参阅图 10, 图 10是本发明的光源系统的又一个实施例的示意图。 在本实施例中， 光源 系统 1000包括发光装置 1、 分光系统 2、 第一空间光调制器 1011与第二 空间光调制器 1013。 发光装置 1包括激发光源 1001、 波长转换层 1003B 与第一驱动装置 1005。 分光系统 2包括第一分光装置 1003A和光引导装 置 3。 波长转换层 1003B和第一分光装置 1003A固定连接， 共同设置在 色轮 1003上。
本实施例与图 7所示实施例的区别之处包括：
波长转换区 1003B设置为反射式的， 即波长转换区 1003B的入射光 的光路与出射光的光路位于其同一侧。 且波长转换区 1003B上的第一区 段 S1与分光区 1003A上的第一分区 W1呈 0度设置， 第二区段 S2与分 光区 1003A上的第二分区 W2呈 0度设置， 即分光区域和与其对应的波 长转换区域相邻设置。
光引导装置 3包括带有通孔的反射镜 1007、 收集透镜 1009和 1015。 在本实施例中， 激发光源 1001为激光光源， 用于产生蓝色激光 101。 反射镜 1007设置在蓝色激光 101的出射光路上。 由于激光的光学扩展量 比较小， 而受激光的光学扩展量较大，使得蓝色激光 101从该通孔穿过并 经收集透镜 1009后进入到波长转换区 1003B上，而波长转换区 1003B出 射的序列光经收集透镜 1009收集后大部分被反射镜 1007反射至分光区 1003A。 其中分光区 1005A上形成的光斑与波长转换区 1005B上形成的 光斑位于色轮 1005上的同一半径线上。 相比图 8所示的光源系统， 本实 施例中的光源系统的光路更加紧凑。
实施例七
请参阅图 11 , 图 11为另一种将波长转换层与第一分光装置固定连接 的光源结构的示意图。 在本实施例中， 光源系统 1100包括发光装置、 分 光系统 2、 第一空间光调制器 1111与第二空间光调制器 1113。 发光装置 包括激发光源 1101、 波长转换层 1103B与第一驱动装置 1105。 分光系统 2包括第一分光装置 1103A和光引导装置 3。波长转换层 1103B和第一分 光装置 1103A固定连接， 共同设置在色轮 1003上。
本实施例与图 10所示实施例的区别之处包括：
波长转换区 1103A与分光区 1103B不是相互嵌套的两个圓环区域。 在色轮 1103的中心区域设置有一圓台 1103C, 波长转换层区 1103B设置 在该圓台 1103C的侧面上， 而分光区 1103A设置在色轮 1103的一个圓环 区域上。 蓝色激光 111依序穿过反射镜 1107的通孔和收集透镜 1109后， 入射到波长转换区 1103B上的其中一个区段上。 而波长转换区 1103B出 射的序列光 113经收集透镜 1109收集后大部分被反射镜 1107反射至分光 区 1103A上与波长转换区 1103B上光斑所在的区段对应的分区。
相比图 10所示的光源系统， 本实施例中由于波长转换区 1103B与分 光区 1103 A相隔的较远， 经反射镜 1107反射前和反射后的序列光 113之 间的夹角较大， 较容易分开光路。
在以上实施例中，波长转换层上的第二分区也可以设置有第二波长转 换材料， 用于吸收激发光并出射第二光。 具体举例来说， 激发光源用于产 生 UV光。 波长转换层的第一分区上设置有黄色荧光粉， 用于吸收 UV光 并产生黄光；第二分区上设置有蓝色荧光粉，用于吸收 UV光并产生蓝光， 该蓝光为第二光。
实施例八
本实施例的光源系统的示意图与以上实施例中的光源系统的示意图 基本一样， 不同的是，在本实施例中分光系统还将第二光分成分别沿第一 光通道和第二光通道出射的第三范围波长光和第四范围波长光，则第一空 间光调制器用于对沿第一光通道出射的第一光的第一范围波长光和第二 光的第三范围波长光进行调制,而第二空间光调制器用于对沿第二光通道 出射的第一光的第二范围波长光进行调制，或者还用于对沿第二光通道出 射的第二光的第四范围波长光进行调制。
以图 5举例来说， 激发光源 501用于产生 UV光。 波长转换层 503 的第一分区上设置有黄色荧光粉， 用于吸收 UV光并产生黄光； 第二分区 上设置有蓝色荧光粉， 用于吸收 UV光并产生蓝光， 该蓝光为第二光。 由 于蓝色荧光粉产生的蓝光的光语较宽，覆盖了绿光光谱的部分范围。分光 系统中的滤光片 505 同时设置为将第二分区产生的第二光即蓝光分光成 第三范围波长光和第四范围波长光， 即第二蓝光和第二绿光。 这样， 产生 的第二蓝光和第二绿光的光谱较窄， 色纯度较高。
相对应地，在将第二分区产生的蓝色受激光分光成第二蓝光和第二绿 光时，在图 2所示的光源系统的分光系统中，可将第二棱镜 209中的镀膜 面 209a同时设置为反射蓝色受激光中的蓝光成分并透射绿光成分， 或者 透射蓝光成分并反射绿光成分。在图 5所示的光源系统的分光系统中，可 将滤光片 505设置为同时反射蓝色受激光中的第二蓝光并透射第二绿光， 或者透射第二蓝光并反射第二绿光。 以上描述中，用于对第一光和第二光 分光的均为分光系统中的同一个分光装置。
在实际运用中，分光系统中也可以分别用两个分光装置分别对第一光 和第二光分光。如图 12所示， 图 12是本发明的光源系统的又一个实施例 的示意图。 本实施例中， 光源系统 1200包括发光装置 1、 分光系统 2、 第 一空间光调制器 1211与第二空间光调制器 1213。发光装置 1包括激发光 源 1201、 波长转换层 1203与第一驱动装置 1205。
本实施例与图 5所示实施例的区别之处包括：
分光系统 2包括滤光片 1221、 1209和 1207, 还包括反射镜 1219。 滤 光片 1221位于发光装置 1出射时序光的光路上， 用于反射蓝色受激光中 的第二蓝光 65b并透射蓝色受激光中的第二绿光 65a以及黄色受激光 63。
滤光片 1209位于滤光片 1221透射光束的出射光路上，用于透射蓝色 受激光中的第二绿光 65a以及黄色受激光 63中的第一绿光 63a并反射黄 色受激光 63中的红光 63b。 因此， 经滤光片 1209透射的第二绿光 65a和 第一绿光 63a沿第一光通道出射至 DMD 1211。 经滤光片 1209反射的红 光 63b再经滤光片 1207反射后沿第二光通道出射至 DMD1213 , 而经滤 光片 1221反射的第二蓝光 65b分别经过反射镜 1219反射和滤光片 1207 透射后沿第二光通道出射至 DMD 1213。
当蓝光 65分光后得到的第二蓝光 65b和第二绿光 65a均用于调制时， 由于两个 DMD用于调制的颜色增多， 使得两个 DMD能够调制的色域更 大。 相对应地， 波长转换层 1203和 DMD1211、 1213的工作时序图如图 13所示。 图 13A是波长转换层 1203出射蓝光和黄光的时序图。在波长转 换层 1203转动的一周期 T时间内，在前 0.25T内， 波长转换层 1203出射 蓝光， 在后 0.75T内， 波长转换层 1203出射黄光。 如图 13 B和图 13C所 示，图 13B和图 13C分别为 DMD1211和 DMD1213对不同色光的调制时 间图。 相对应地， 前 0.25T内 DMD1211用于调制第二绿光， DMD 1213 用于调制第二蓝光。后 0.75T内 DMD 1211用于调制第一绿光， DMD 1213 用于调制红光。
容易理解的是， 第二绿光也可以不用于调制， 在其进入 DMD 1211 时只要 DMD 1211不工作， 即可不调制这部分光。
以上实施例中都是利用光波长的差异，使用滤光片或者滤光膜对光束 进行透射和反射来进行分光或者合光。而某一个光路上的光在一个分光滤 光片上被透射还是被反射， 是可以任意设计的。 因此， 在本发明的所有实 施例中， 各光路上不同波长范围光通过滤光片或滤光膜的具体的光学结 构，都是为了方便说明而列举的例子， 并不限制使用其它的利用分光滤光 片或滤光膜进行光路合并或光束分光的光学结构。
在本实施例中， 波长转换层 1203上也可以设置多个分区， 其中不同 分区上设置有不同波长转换材料或者透光区。并且至少一个分区上出射的 光束被分光成两种不同波长范围的光以使得该两种不同波长范围光分别 进入两个空间光调制器中进行调制。
在本实施例中，第一分区和第二分区也可以设置产生其他颜色光的波 长转换材料，并不局限上述的黄色荧光粉和蓝色荧光粉。波长转换材料也 还可能是量子点、荧光染料等具有波长转换能力的材料，并不限于荧光粉。
实施例九
请参阅图 14, 图 14是本发明的光源系统的又一个实施例的发光光源 的示意图。与以上实施例不同的是， 以上实施例中发光装置 1通过色轮来 产生时序光，而本实施例中发光装置 1通过转动的反射镜来依次反射 LED 灯盘发出的不同颜色光出射以产生时序光，相比实施例一，本实施例中采 用反射镜能控制成本。
具体来说， 发光装置 1 包括发光光源组 1401、 第一反射装置 1405、 第二反射装置 1403和第二驱动装置 （图未示）。
发光光源组 1401 包括第一发光器件 （在本实施例中为黄光荧光粉 LED 1401a )和第二发光器件（在本实施例中为蓝光 LED 1401b ), 其中 荧光粉 LED指将荧光粉涂覆在 LED芯片的表面， 利用 LED发出的光来 激发荧光粉并发出荧光。 常见的黄光荧光粉 LED指将黄色荧光粉涂覆于 蓝光 LED芯片表面， 并被蓝光 LED发射出的蓝光所激发产生黄色光。 黄 光 LED 1401a和蓝光 LED 1401b呈环状分布， 并且黄光 LED 1401a和蓝 光 LED 1401b出射光的方向均平行于过该环状的圓心的中心轴。
第二反射装置，在本实施例中为一转动镜 1403 ,其包括反射面 1403a, 设置于发光光源组 1401的出射光的一侧， 并位于第一发光器件 1401a和 第二发光器件 1401b之间。
第一反射装置 1405包括两个反射元件， 在本实施例中均为反射镜， 分别位于第一发光器件 1401a和第二发光器件 1401b的出射光路上，用于 将不同发光器件的出射光反射至第二反射装置 1403。
第二驱动装置 1403驱动第二反射装置 1403运动， 使得反射面 1403a 依次置于第一反射装置 1405的两个反射元件的出射光路上， 以将第一、 第二发光器件发出的光依次反射出射。
在实际运用中， 发光光源组 1401也可以包括多个发光器件阵列， 在 本实施例中为 LED阵列。 相对应地， 反射装置组 1405包括多个反射镜， 分别置于光源 1401中多个发光器件阵列的出射光路上。
如图 15所示，图 15为本实施例中的发光光源组 1401的结构示意图。 发光光源组 1401中的各 LED设置在以转动镜 1403为圓心的圓盘上， 并 围绕转动镜 1403沿周向排布，并以转动镜 1403为中心沿径向呈阵列分布。 沿径向的阵列分布中， LED阵列中为发出同一种颜色光的 LED, 沿周向 排布中， 黄光荧光粉 LED 1401a和蓝光 LED 14101b交替分布。
实施例十
请参阅图 16, 图 16是本发明的光源系统的又一实施例的示意图。 光 源系统 1600包括发光装置 1、 分光系统 2、 第一空间光调制器 1611与第 二空间光调制器 1613。
本实施例与图 5所示实施例的区别之处包括：
发光装置 1包括第一发光器件、第二发光器件和第一控制装置（图未 示），其中第一发光器件用于产生第一光，第二发光器件用于产生第二光； 第一控制装置用于在至少部分时段将第一发光器件和第二发光器件交替 点亮， 以出射时序的第一光和第二光。
具体来说，第一发光器件为黄光 LED 11a,第二发光器件为蓝光 LED l ib, 分别用于产生黄光和蓝光。 第一控制装置用于分别控制不同颜色的 发光器件的开启与关闭， 使蓝光 LEDl lb和黄光 LEDl la交替点亮， 以产 生时序的黄光和蓝光。
在本实施例中，在某一时段第一控制装置可以控制黄光 LEDl la和蓝 光 LEDl lb 同时点亮。 由于蓝光以及黄光分光后得到的绿光均在 DMD 1611中进行调制，则在黄光 LEDl la和蓝光 LEDl lb同时点亮的这个时间 段中， DMD1611用于对蓝光和绿光的合光即青色光进行调制，对于 DMD 1613则没有影响。在这个时间段中， 由于两种光的混合，使得 DMD 1611 能够调制多一种颜色， 使得该 DMD 1611能够调制的色域更大。
如图 17A所示， 图 17A为光源系统 1600出射光的颜色时序图。在一 个周期 T内， 在 tl时间内， 点亮蓝光 LED, 则发光装置 1出射蓝光； 在 t2时间内， 点亮黄光 LED, 则发光装置 1出射黄光； 在 t3时间内， 同时 点亮蓝光 LED和黄光 LED,则发光装置 1出射该两种光的合光，即白光。 如图 17 B和图 17 C所示，图 17B和图 17C分别为 DMD1209和 DMD1211 对不同色光的调制时间图。 相对应地， tl时间内 DMD 1611用于调制蓝 光， DMD1613 未工作； t2 时间内 DMD1611 用于调制绿光， DMD1613 用于调制红光； t3时间内， DMD1611用于调制青光， DMD1613用于调 制红光。
但是， 不能一直使该两种颜色光同时点亮， 由于本光源系统中只有两 个 DMD, 其中一个 DMD用于在不同的时段分别调制蓝光和绿光。 如果 黄光 LEDl la和蓝光 LEDl lb—直保持同时点亮， 则导致没有蓝光和绿光 这两种单色光图像， 而只有青色光的图像。
容易理解的是， 如果分光系统 2中的滤光片 1609用于透射红光并反 射绿光，则蓝光和黄光分光后得到的红光均在 DMD 1611中进行调制，绿 光在 DMD 1613中进行调制。则在黄光 LEDl la和蓝光 LEDl lb同时点亮 的这个时间段中，该 DMD 1611用于对蓝光和红光的合光即紫色光进行调 制， 对于 DMD 1613则没有影响。
相比以上实施例，本实施例能同时点亮不同颜色的发光器件，使得用 于调制的颜色光更多， 进而能够调制的色域更大。
实施例十一
请参阅图 18, 图 18是本发明的光源系统的又一实施例的示意图。 本 实施例中， 光源系统 1800包括发光装置 1、 分光系统 2、 第一空间光调制 器 1811与第二空间光调制器 1813。
本实施例与图 16所示实施例的区别之处包括：
分光系统 2包括滤光装置 1805、 用于驱动滤光装置运动的第二驱动 装置 1806和第一控制装置 （图未示）。 滤光装置 1805上包括第一区段、 第二区段和第三区段，其中第一区段用于透射第一光的第一范围波长光至 第一光通道出射，并反射第二范围波长光至第二光通道出射； 第二区段用 于反射第一光的第一范围波长光至第二光通道出射，并透射第二范围波长 光至第一光通道出射； 第三区段用于透射部分第二光至第一光通道出射， 并反射部分第二光至第二光通道出射。第一控制装置用于控制第二驱动装 置 1806, 以使第一区段的至少部分和第二区段的至少部分依次位于第一 光的出射光路上， 第三区段的至少部分位于第二光的出射光路上。
具体举例来说， 如图 19所示， 图 19是图 18所示的光源系统中的滤 光装置的主视图的一个实施例。 滤光装置 1805呈圓盘状， 其上的各个区 段在该圓盘上沿周向分布。 该滤光装置 1805上的第一区段 1805A用于透 射部分蓝光并反射部分蓝光， 第二区段 1805B用于透射绿光并反射红光， 第三区段 1805C用于反射绿光并透射红光。 第二驱动装置 1806为马达， 用于驱动滤光装置 1805周期性转动， 以使各个区段依次位于发光装置 1 的出射光路上。
如图 20所示， 图 20是图 18所示的光源系统的两个光源的发光时序 图与两个 DMD的调制时序图。 在一个调制周期 T内， 在前 tl时间内， 滤光装置 1805的第一区段 1805A位于时序光的出射光路上， 则蓝光光源 1801点亮， 黄光光源 1802不工作， 则两个 DMD用于调制蓝光。 在接下 来的 t2时间内，滤光装置 1805的第二区段 1805B位于时序光的出射光路 上， 黄光光源 1802点亮， 蓝光光源 1801不工作， 则 DMD1811用于调制 绿光， DMD1813用于调制红光。 在接下来的 t3时间内， 滤光装置 1805 的第三区段 1805C位于时序光的出射光路上， 黄光光源 1802点亮， 蓝光 光源 1801不工作，则 DMD1811用于调制红光， DMD1813用于调制绿光。 这样， 可以使得两个 DMD分别调制时序的三基色光。
实施例十二
请参阅图 21 , 图 21是图 18所示的光源系统中的滤光装置的主视图 的又一个实施例。
在本实施例中， 滤光装置 1805上还包括第四区段， 用于反射蓝光并 透射黄光， 并且与图 18所示的光源系统不同的是， 第一区段 1805A用于 透射蓝光并反射黄光； 当第一区段 1805A和第四区段 1805D位于时序光 的出射光路上时， 蓝光光源 1801和黄光光源 1802同时点亮。 相对应地， 在一个调制周期 T内， 当滤光装置 1805的第一区段、 第二区段、 第三区 段和第四区段依次位于时序光的出射光路时， DMD 1811依次调制蓝光、 绿光、 红光和黄光， DMD 1813依次调制黄光、 红光、 绿光和蓝光。 在本 实施例中， 由于调制的颜色增添了黄光， 使得光源系统的亮度提高。
在图 18所示的光源系统中， 采用一个蓝光光源和一个黄光光源对应 滤光装置上的不同分光区时序点亮来分别为两个 DMD 提供至少三个时 序光， 其中该蓝光光源产生的光被分光成两束蓝光至该两个 DMD。 在实 际运用中， 也可以将采用两个蓝光光源提供两束蓝光分别用于两个 DMD 调制。 具体说明如下。
实施例十三
请参阅图 22, 图 22是本发明的光源系统的又一实施例的示意图。 本 实施例中， 光源系统 2200包括发光装置、 分光系统、 第一空间光调制器 2211与第二空间光调制器 2213。 发光装置包括第一发光器件 2201 A、 第 二发光器件 2202、 第三发光器件 2201B和第一控制装置（图未示）。 分光 系统包括滤光装置 2205、 第二驱动装置 2206、 滤光片 2203和 2204。
本实施例与图 18所示实施例的区别之处包括：
发光装置还包括第三发光器件，用于在出射第二光的至少部分时段产 生第四光。 在本实施例中， 该第三发光器件为蓝光光源 2201B。 分光系统 中的滤光装置 2205包括两个区段，即图 18所示的光源系统中的滤光装置 1805上的第二区段和第三区段。 如图 23所示， 图 23是图 22所示的光源 系统中滤光装置 2205的主视图。 滤光装置 2205上包括第一区段 2205A (即滤光装置 1805上的第二区段），用于透射绿光并反射红光；还包括第 二区段 2205B (即滤光装置 1805上的第三区段）， 用于透射红光并反射绿 光。
黄光光源 2202发出的黄光（即第一光） 以一定角度入射到滤光装置 2205上， 经滤光装置 2205反射的光束经滤光片 2204透射后沿第一光通 道出射至 DMD 2211 ; 经滤光装置 2205透射的光束经滤光片 2203透射后 沿第二光通道出射至 DMD2213。蓝光光源 2201A发出的光束（即第二光） 经滤光片 2204反射后沿第一光通道出射后至 DMD 2211。蓝光光源 2201 B 发出的光束（即第四光）经滤光片 2203反射后沿第二光通道出射至 DMD 2213。
在一个调制周期 T内， 在前 tl时间内， 第一控制装置关闭黄光光源 2202, 并同时点亮蓝光光源 2201A和 2201B , DMD2211和 2213均用于 调制蓝光。 在后 t2时间内， 第一控制装置点亮黄光光源 2202并关闭蓝光 光源 2201A和 2201B, 第一区段 2203A和第二区段 2203B的至少部分区 段依次位于黄光的出射光路上时。 DMD 2211用于调制沿第一光通道依次 出射的红光和绿光， DMD 2213用于调制沿第二光通道依次出射的绿光和 红光。
在本实施例中， 可以分别控制两个 DMD中调制的蓝光的光强度， 以 更好地适应实际需要。 并且， 两个蓝光出射的时间长度也可以不一致， 其 中一个蓝光光源可以在另一个蓝光光源点亮的部分时间段内点亮，具体点 亮的时间长短可根据与其对应的 DMD 需要蓝光的量来决定。 同样道理 的， 为调节用于调制的绿光和红光的量，可以相应地控制第一区段 2203A 和第二区段 2203B分别位于黄光（即第一光） 的出射光路上时黄光的点 亮时间。容易理解的是，其中一个蓝光光源也可以替换成其他颜色的发光 元件，例如青色发光元件，相对应地其中一个 DMD用于调制时序的青光、 红光和绿光。
可以理解的是，本实施例中分光系统中的滤光片 2203和 2204不是必 须的，可以通过改变光源系统的光路结构来省略掉该两个滤光片。例如将 滤光装置 2205上的各个区段同时还设置为透射第二光和第四光（本实施 例中均为蓝光）， 并将光源 2201A和 2201B分别位于滤光装置 2205的两 侧， 使得光源 2201A出射的光经滤光装置 2205透射后直接入射至 DMD 2211 , 光源 2201B 出射的光经滤光装置 2205 透射后直接入射至 DMD 2213。
实施例十四 请参阅图 24, 图 24是本发明的光源系统的又一个实施例的发光光源 的示意图。 本实施例中， 光源系统 2200包括发光装置、 分光系统、 第一 空间光调制器 2211与第二空间光调制器 2213。
发光装置用于依序出射第一光、 第二光和第三光。 具体举例来说， 发 光装置包括黄光光源 2402A、 蓝光光源 2401和黄光光源 2402B, 分别用 于产生黄光 22A、 蓝光 11和黄光 22B , 即第一光、 第二光和第三光； 还 包括第一控制装置 2403 , 用于控制该三个光源， 使得发光装置依序出射 黄光 22A、 蓝光 11和黄光 22B。
分光系统用于将来自发光装置的第二光分成沿第一光通道和第二光 通道出射的第一子光和第二子光，还用于将来自发光装置的第三光分成沿 第一光通道和第二光通道出射的第五范围波长光和第六范围波长光。具体 举例来说， 分光系统包括滤光片 2404和 2405。 滤光片 2405的滤光曲线 设置为透射黄光的绿光成分，即第一光的第一范围波长光和第三光的第五 范围波长光，并反射红光成分， 即第一光的第二范围波长光和第三光的第 六范围波长光；还透射部分蓝光并反射部分蓝光，即第一子光和第二子光。 滤光片 2404用于透射蓝光并反射黄光。 蓝光光源 2401和黄光 2402A产 生的光分别从滤光片 2404的两侧入射，分别经滤光片 2404透射和反射后 从同一光通道至滤光片 2405的同一侧入射。 黄光光源 2402B产生的光从 滤光片 2405的另一侧入射。经滤光片 2405反射的光沿第一光通道出射至 DMD 2411 , 经滤光片 2405透射的光沿第二光通道出射至 DMD 2413。
第一空间光调制器（即 DMD 2411 )用于对分光系统沿第一光通道依 序出射的第一范围波长光、第一子光和第五范围波长光进行调制。第二空 间光调制器（即 DMD 2413 )用于对所述分光系统沿第二光通道依序出射 的第二范围波长光、 第二子光和第六范围波长光进行调制。
如图 25所示， 图 25是图 24所示的光源系统的三个光源的发光时序 图与两个 DMD的调制时序图。 在一个调制周期 T内， 在前 tl时间内， 蓝光光源 2401点亮， 两个黄光光源不工作， 则两个 DMD均用于调制蓝 光。 在接下来的 t2时间内， 黄光光源 2402B点亮， 其余两个光源不工作， 则 DMD2411用于调制绿光， DMD2413用于调制红光。 在接下来的 t3时 间内， 黄光光源 2502A点亮， 其余两个光源不工作， 则 DMD2411用于调 制红光， DMD2413用于调制绿光。 这样， 便可以使得两个 DMD分别调 制时序的三基色光。
本实施例中， 也可以在一个调制周期 T 内加入时间段 t4, 在该时间 内， 三个光源同时点亮， 则两个 DMD用于调制蓝光和黄光的合光， 即白 光。 这样， 可以提高光源系统的亮度。 在本实施例中， tl、 t2、 t3和 t4的 比例可以根据对不同颜色的实际比例需要来进行调整。
相比以上实施例，本实施例中可通过分别控制两个黄光光源的亮度来 分别对两个 DMD接收到的红光和绿光的亮度进行调整，并且减少了对滤 光装置驱动的第二驱动装置的使用； 同时， 由于光源的点亮不需与滤光装 置的转动相同步， 在控制不同光源的时序点亮上更加容易， 在调整 DMD 对不同颜色光调制的量也更加方便。
容易理解的是，本实施例中的其中一个黄光光源也可以替换成第三颜 色的发光元件。 相对应的， 用于分光的滤光片 2405的滤光曲线同时还设 置为透射第三颜色光的一个波长范围的光并反射第三颜色光的另一波长 范围光。
在本实施例中 ,发光装置中还可以通过激发光激发转动的色轮而产生 三束时序光，而分光系统中也可以通过与色轮同时转动的滤光轮来对该三 束时序光进行分光来实现。 以上实施例已经对这些装置进行描述，只需简 单的对不同实施例中的发光装置和分光系统进行组合即可， 在此不再赘 述。
实施例十五
请参阅图 26, 图 26是本发明的光源系统的又一个实施例的发光光源 的示意图。 本实施例中， 光源系统 2600包括发光装置、 分光系统、 第一 空间光调制器 2211 与第二空间光调制器 2213。 发光装置包括蓝光光源 2601 A和 2601B、 黄光光源 2602A和 2602B、 第一控制装置 2603。 分光 系统包括滤光片 2404和 2405。
本实施例与图 24所示实施例的区别之处包括：
本实施例中的发光装置还包括蓝光光源 2601B , 和蓝光光源 2601 A 分别为两个 DMD提供蓝光。
相比图 24所示的光源系统中用于对两个黄光光源产生的光束进行分 的滤光片 2605设置为透射绿光和蓝光并反射红光， 且蓝光 2601A产生的 蓝光经滤光片 2605透射后沿第二光通道出射至 DMD 2613。 同时， 滤光 片 2606位于滤光片 2605反射光束的出射光路上，用于透射蓝光并反射其 他光。经滤光片 2605反射的时序的红光和绿光经滤光片 2606反射后沿第 一光通道出射至 DMD 2611 , 蓝光光源 2501B从滤光片 2606透射后沿第 一光通道出射至 DMD 2611。
如图 27所示， 图 27是图 26所示的光源系统的四个光源的发光时序 图与两个 DMD的调制时序图。 在一个调制周期 T内， 在前 tl时间内， 第一控制装置控制两个蓝光光源点亮，两个黄光光源不工作，则两个 DMD 用于调制蓝光。 在接下来的 t2时间内， 黄光光源 2602B点亮， 其余三个 光源不工作， 则 DMD2611用于调制绿光， DMD2613用于调制红光。 在 接下来的 t3 时间内， 黄光光源 2602A 点亮， 其余三个光源不工作， 则 DMD2611 用于调制红光， DMD2613 用于调制绿光。 这样， 便可以使得 两个 DMD分别调制时序的三基色光。
容易理解的是， 其中一个蓝光光源也可以只在时间段 tl 的部分时间 段内点亮即可，其中具体点亮的时间长短可根据实际需要的蓝光的量来进 行控制。
优选地 , 在一个调制周期 T内， 也可以加入时间段 t4 , 在该时间内 , 四个光源同时点亮，则两个 DMD均用于调制蓝光和黄光的合光，即白光。 这样， 可以提高光源的亮度。 在本实施例中， tl、 t2、 t3和 t4的比例可以 根据对不同颜色的实际比例需要来进行调整。
相比图 24所示的光源系统， 本实施例中采用两个蓝光光源， 可以分 别控制两个 DMD中调制的蓝光的光强度和调制时间的长短，以更好地适 应实际需要。
在以上实施例中， 每个滤光片的滤光曲线、 各个光源的时序控制、 DMD的调制时序和具体光路结构等等并不限于以上的举例， 本技术领域 人员可根据本发明具体设计。
实施例十六
请参阅图 28, 图 28是本发明的光源系统的又一个实施例的发光光源 的示意图。 本实施例中， 光源系统 2800包括发光装置、 分光系统、 第一 空间光调制器 2811 与第二空间光调制器 2813。 发光装置包括激发光源 2801和 2802、波长转换层 2805、第一驱动装置 2806和第一控制装置（图 未示）。 分光系统包括滤光片 2814和反射镜 2812。
本实施例与图 24所示实施例的区别之处包括：
图 24所示的光源系统中发光装置通过时序点亮四个光源来产生时序 光，而本实施例中的发光装置采用色轮结合时序点亮光源两种方式来产生 时序光， 具体说明如下。
波长转换层 2805上包括第一分区 2805A、 第二分区 2805B、 第三分 区 2805C和第四分区 2805C , 分别设置有第一、 第二、 第三和第四功能 材料， 分别用于吸收激发光并产生第一、 第二、 第三、 第四光。 在本实施 例中， 两个激发光源均为 UV光， 第一和第三分区上均设置有黄光波长转 换材料， 第二和第四分区上均设置有蓝光波长转换材料。在同一时间段内 第一分区和第三分区分别位于两个激发光源产生的激发光的出射光路上， 另一时间段内第二分区和第四分区分别位于两个激发光源产生的激发光 的出射光路上。
第一驱动装置 2806用于驱动波长转换层 2805 ,使得激发光在波长转 换层 2805上形成的光斑按预定路径作用于该波长转换层 2806。 同时， 第 一控制装置用于控制两个激发光源， 使得当第一分区 2805A和第三分区 2805C位于两束激发光的光路上时的至少部分时段交替点亮，当第二分区 2805B和第四分区 2805D位于两束激发光的光路上时至少部分时段同时 点亮。
以下具体举例来说明。 如图 29所示， 图 29是图 28所示的光源系统 中的波长转换层的主视图的一个实施例。在本实施例中，波长转换层 2805 呈圓盘状， 且第一分区 2805A和第三分区 2805C呈 180度设置， 第二分 区 2805B和第四分区 2805D呈 180度设置。 第一驱动装置 280为马达， 用于驱动波长转换层周期性转动。 两束激发光在波长转换层 2805上各自 形成的光斑的连线经过圓盘的圓心，使得在同一时间内呈 180度设置的分 区分别位于该两个激发光源产生的激发光的出射光路上。
在本实施例中， 波长转换层 2805设置为反射式的， 即激发光与受激 光的光路位于该波长转换层 2805 的同一侧。 可通过在波长转换层 2805 背向激发光源的一侧放置反射镜或者镀有反射膜来实现， 此为公知技术 , 在此不再赘述。
在波长转换层 2805的出射光路上设置有两个反射罩 2803和 2804, 分别用于收集激发光源 2801和激发光源 2802激发波长转换层所产生的受 激光，分别称为第一受激光和第二受激光。该两个反射罩上各自设置有一 通孔，用于透射与其对应的激发光源产生的激发光。该两个反射罩利用激 发光和受激光的光学扩展量的差异将激发光和受激光的光路区分开来。容 易理解的是， 波长转换层为透射式时， 即激发光的光路和受激光的光路分 别位于波长转换层的两侧，可以不需要使用反射罩。但本实施例中采用反 射式的波长转换层和反射罩， 能够减少光束的损失， 提高光束利用率。
分光系统用于将第一光和第三光分别分成沿第一光通道和第二光通 道出射的两束不同波长范围光，并分别沿第一光通道和第二光通道出射第 二光和第四光。 在本实施例中， 反射镜 2812位于第二受激光的出射光路 上， 第一受激光和经反射镜 2812 反射的第二受激光分别入射至滤光片 2811的两侧。 滤光片 2814用于反射黄光（即第一光和第三光） 中的绿光 成分并透射红光成分， 还用于反射蓝光（即第二光和第四光）沿第一光通 道和第二光通道出射。 DMD 2811用于对经滤光片 2814沿第一光通道出 射的光束进行调制。 DMD 2813用于对经滤光片 2814沿第二光通道出射 的光束进行调制。
优选地， 第一受激光经反射罩 2803 收集后依次进入勾光装置 2807 匀光和收集透镜 2810后再出射至滤光片 2811。 同样的， 第二受激光经反 射罩 2804收集后依次进入勾光装置 2808勾光和收集透镜 2809后再出射 至滤光片 2811。 这样， 能提高第一受激光和第二受激光的利用率， 减少 光损失。
如图 30所示， 图 30是图 28所示的光源系统的一种工作时序图。 具 体说明如下。在波长转换层 2805转动的一个周期 T内，当第二分区 2805B 和第四分区 2805D分别位于两束激发光的光路上时， 第一控制装置控制 两个激发光源点亮， 则两个 DMD同时接收到滤光片 2811反射的蓝光； 当第一分区 2805A和第三分区 2508C分别位于两束激发光的光路上时， 在前 tl 时间内， 第一控制装置控制激发光源 2802点亮， 激发光源 2801 关闭，则 DMD2813接收到绿光， DMD 2811接收到红光；在后 t2时间内， 第一控制装置控制激发光源 2801点亮，激发光源 2802关闭，则 DMD2813 接收到红光， DMD2811接收到绿光。
优选地， 当第一分区 2805A和第二分区 2805C分别位于两束激发光 的光路上时， 期间有部分时间段 t3内， 第一控制装置控制激发光源 2801 和 2802同时点亮， 则两个 DMD同时接收到红光和绿光的合光， 即黄光。 这使得光源系统的亮度提高。
在本实施例中， 当第二分区 2805B和第四分区 2805D分别位于两束 激发光的光路上时，可以调整两束激发光的工作时间的长短， 以调整两个 DMD分别接收到的蓝光的量，进而调整最终光源系统出射的图像的颜色。 同样道理的， 也可以在第一分区 2805A和第三分区 2805C分别位于两束 激发光的光路上时，分别调整两束激发光的工作时间的长短， 以调整两个 DMD分别接收到的时序红、 绿光的量。
在本实施例中， 两个激发光源也可以是蓝光光源， 第二分区 2805B 和第四分区 2805D上均设置有反光区， 用于反射蓝光。 当激发光源为激 光光源时， 优选地， 第二分区 2805B和第四分区 2805D还设置有散射材 料， 用于对蓝光进行消相干。
在本实施例中， 第一、 第二、 第三和第四光也可以是不同颜色光， 可 根据两个 DMD 分别需要调制的光来决定该四束光的光谱以及用于将第 一光和第三光分光的滤光片的滤光曲线。
实施例十七
请参阅图 31 , 图 31是本发明的光源系统的又一个实施例的发光光源 的示意图。 本实施例中， 光源系统 3100包括发光装置、 分光系统、 第一 空间光调制器 3111 与第二空间光调制器 3113。 发光装置包括激发光源 3101和 3102、波长转换层 3105、第一驱动装置 3106和第一控制装置（图 未示）。 分光系统包括滤光片 3109、 带有通孔的反射镜 3103和 3104。
本实施例与图 28所示实施例的区别之处包括：
图 28所示的光源系统中在波长转换层 2805的出射光路上放置反射 罩，使得发光装置发出的时序光经反射罩收集后再进入分光系统。在本实 施例中， 不在波长转换层 3105的出射光路上放置反射罩， 而是直接放置 分光系统。
分光系统中的滤光片 3109用于透射黄光中的绿光成分并反射黄光中 的红光成分，还用于分别透射第二光和第四光（在本实施例中均为蓝光）。 第一激发光源 3101产生的激发光依次经过反射镜 3103上的通孔和准直透 镜 3108后入射至波长转换层 3105。 波长转换层 3105出射的第一受激光 经准直透镜 3108准直后被反射镜 3103反射至滤光片 3109。 第二激发光 源 3102产生的激发光依次经过反射镜 3104上的通孔、 滤光片 3109和准 直透镜 3107后入射至波长转换层 3105。 波长转换层 3105出射的第二受 激光经准直透镜 3107准直后进入滤光片 3109。
图 31所示的光源系统的工作时序具体举例如下。在波长转换层 3108 转动的一个周期 T内， 当第二分区 2805B和第四分区 2805D分别位于两 束激发光的光路上时， 第一控制装置控制两个激发光源点亮， 则 DMD 3113接收到滤光片 3109透射的蓝光， DMD 3111 接收到依次经滤光片 3109 透射和反射镜 3104反射的蓝光； 当第一分区 2805A和第三分区 2805C分别位于两束激发光的光路上时， 在前 tl 时间内， 第一控制装置 控制激发光源 3101点亮，激发光源 3102关闭，则 DMD3113接收到红光， DMD3111接收到绿光；在后 t2时间内，第一控制装置控制激发光源 3102 点亮， 激发光源 3101关闭， 则 DMD3113接收到绿光， DMD3111接收到 红光。
为方便描述，在以上各实施例中均采用第一光和第三光为黄光， 第二 光和第四光为蓝光为例子说明。在实际运用中，该四束光也可以为其他颜 色光， 并不限定于以上所描述的。相对应的， 分光系统中的滤光片或者滤 光装置的滤光曲线也根据该四束光的具体颜色而具体设计。
在以上各实施例中，具有不同分区的波长转换层和不同区段的滤光装 置中，波长转换层或者滤光装置上的不同区域也可以不是围绕一个圓心周 向分布 ,而是呈平行设置的带状区域或采取其他适当设置方式。相对应的 , 用于驱动该波长转换层或者滤光装置运功的驱动装置可以是线性平移装 置或采取其他适当设置方式，以使得光束在该波长转换层或者滤光装置上 形成的光斑分别沿直线路径或者其他预定路径作用于该波长转换层或者 滤光装置。
在以上各实施例中， 两个 DMD 出射的光可以投射到同一显示区域 内， 以形成一幅图像， 如图 32所示， 图 32是本发明的光源系统的一个实 施例的结构示意图。 两个 DMD 出射的光也可以分别投射到两个显示区 域， 以形成两幅图像， 如图 33所示。 图 33是本发明的光源系统的又一个 实施例的结构示意图。
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。
本发明实施例还提供一种投影系统， 包括光源系统，该光源系统可以 具有上述各实施例中的结构与功能。 该投影系统可以采用各种投影技术， 例如液晶显示器 （LCD, Liquid Crystal Display )投影技术、 数码光路处 理器（DLP, Digital Light Processor )投影技术。 此外， 上述发光装置也 可以应用于照明系统， 例如舞台灯照明。
以上所述仅为本发明的实施方式， 并非因此限制本发明的专利范围， 凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直 接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范 围内。
