具体实施方式
请参阅图1，是本发明光源装置第一实施例的结构示意图。如图1所示，本实施例光源装置1包括光源模组101、聚光透镜102a、第一聚光透镜组102b、第二聚光透镜组102c、分光装置103、滤光装置104、反光装置105及色轮模组106。
光源模组101，用于发射偏振方向不同的第一光线S10和第二光线S20，本实施例中，第一光线S10和第二光线S20为偏振方向相互垂直的p光和s光。分光装置103可透射第一光线S10，反射第二光线S20。反光装置105，可以接收被分光装置103反射的第二光线S20并将第二光线S20的偏振方向转换为与第一光线S10的偏振方向一致后反射至分光装置103。色轮模组106，包括色轮1061和转轴1062，随着转轴1062的转动，固定在其上的色轮1061可随之转动。色轮1061上涂覆有波长 转换材料，可以将第一光线S10转换为第三光线S30，并反射至滤光装置104；滤光装置104，用于透射第一光线S10、反射第三光线S30。滤光装置104还用于透射经反光装置105转换了偏振方向并反射的第二光线S21。第二光线S21和第三光线S30形成混合光线后输出。聚光透镜102a，设置在光源模组101和分光装置103之间，用于会聚光源模组101发射的光线；第一聚光透镜组102b设置在分光装置103和反光装置105之间，用于进一步会聚光线，第二聚光透镜组102c设置在色轮模组106与滤光装置104之间，用于进一步会聚光线，第一聚光透镜组102b和第二聚光透镜组102c均包括三个聚光透镜。聚光透镜102a也可以替换为聚光透镜组，第一聚光透镜组102b和第二聚光透镜组102c的透镜数量也可以根据实际需求进行增减。
所述光源装置1的工作原理描述如下：
光源模组101发射的第一光线S10被分光装置103透射至滤光装置104后，进一步被滤光装置104透射至色轮模组106，色轮模组106将第一光线S10的波长进行转换后形成第三光线S30，并反射第三光线S30至滤光装置104，滤光装置104再反射第三光线S30至出光口107；
同时光源模组101发射的第二光线S20被分光装置103反射至反光装置105，由反光装置105将第二光线S20的偏振方向转换为与第一光线S10一致后，反射回分光装置103，并被分光装置103和滤光装置104分别透射至出光口107，与第三光线S30混合形成混合光线。
在本实施例中，光源模组101为激光模组，发射的第一光线S10和第二光线S20均为蓝色激光，而且二者的偏振方向相互垂直，第一光线 S10为p光，第二光线S20为s光。分光装置103具体为偏光分光片，可透射蓝色p光，反射蓝色s光，当激光模组发射蓝色p光和蓝色s光到偏光分光片后，蓝色p光被透射，蓝色s光被反射。蓝色p光被透射后，到达滤光装置104。滤光装置104具体为一滤光片，能够透射波长较短的蓝光，反射波长较长的光线，如黄光。当蓝色p光进一步被滤光片透射后，入射到色轮模组106的色轮1061上。本实施中，色轮1061为单色色轮，涂覆有波长转换材料，具体为黄色荧光粉，可将蓝光转换为黄光。因此当蓝色p光入射到色轮1061上后，成为激发光，激发色轮上的荧光粉发出黄色的发射光，也就是第三光线S30(黄色p光)。第三光线S30(黄色p光)被色轮1061反射到滤光装置104，此时，第三光线S30(黄色p光)的波长比第一光线S10(蓝色p光)的波长长(蓝光的波长范围为435-450nm，黄光的波长范围为577-597nm)，因此，滤光装置104可反射第三光线S30至出光口107。
第二光线S20(蓝色s光)被分光装置103反射后，入射到反光装置105，该反光装置105具体为反蓝陶瓷片，可将第二光线S20(蓝色s光)转换为第二光线S21(蓝色p光)，即转换其偏振方向，其他光谱特性不变，并将第二光线S21反射回分光装置103。此时，因为第二光线S21的偏振方向与第一光线S10的偏振方向一致，因此可被分光装置103透射至滤光装置104，滤光装置104能够透射波长较短的蓝光，因此将进一步透射第二光线S21至出光口107。汇合后的第二光线S21和第三光线S30形成混合光线(白光)后成为照明光源从出光口107输出。
请参阅图2，是本发明光源装置第一实施例单色色轮的结构示意图。 如图2所示，当色轮1061为单色色轮时，两组蓝光可以采用直流点亮的方式，光源模组101至少包括两个激光器，每个激光器的功率可以独立调节，通过独立调节激光器的电流大小可以调节入射至色轮1061的第一光线S10的激光功率P1，和入射至反光装置105的第二光线S20的激光功率P2。不同的激光功率P1激发色轮1061上的荧光粉得到的发射光，也就是第三光线S30的光通量Φ(P 1)不同。在色轮1061涂覆的荧光粉可以转换的波长确定的情况下，蓝光激发荧光粉得到的发射光的光谱特性也是可预知的，也就是第一光线S10的激光功率P1和色轮1061上涂覆的荧光粉决定了第三光线S30的色坐标x(m)y(m)。激光功率P2也决定了入射到出光口107的蓝光的光通量Φ(P 2)，因此其光谱特性也可确定，也就是在第二光线S20的激光功率P2确定的情况下，第二光线S20的色坐标x(n)y(n)也可以确定。那么最终混合得到的混合光线，也就是白光的光通量Φ(W)和色坐标x(W)y(W)满足如下关系：
Φ(W)＝Φ(P 1)+Φ(P 2)
Figure PCTCN2018088383-appb-000001
Figure PCTCN2018088383-appb-000002
其中，W代表混合光线，m代表第一光线S10，n代表第二光线S20，P 1代表第一光线S10的激发功率，P 2代表第二光线S20的激发功率，Φ(W)表示混合光线的光通量，Φ(P 1)表示第一光线S10的光通量，Φ(P 2)表示第二光线S20的光通量，x(m)和y(m)表示第一光线S10的色坐标 的横坐标和纵坐标，x(n)和y(n)表示第二光线S20的色坐标的横坐标和纵坐标，x(W)和y(W)表示混合光线的色坐标的横坐标和纵坐标。
当光通量Φ(P 1)、Φ(P 2)任意一个发生变化时，混合光线的光通量和色坐标均会发生变化。因此，可以通过调节第一光线S10和第二光线S20的激光功率，来达到调整混合光线光通量的目的。当蓝光越多，混合光线的色温就会越高，反之蓝光越少，混合光线的色温也就越低。激光功率越高，光通量越大，反之，激光功率越低，光通量越小。因此，根据实际对光源的需求，可以调整第一光线S10和第二光线S20的激光功率，使其相同或不同，以调整混合光线的光通量和色温。
当第一光线S10和第二光线S20满足以下关系时，还可以实现防蓝光炫目的目的：
Figure PCTCN2018088383-appb-000003
Figure PCTCN2018088383-appb-000004
其中，P 1代表第一光线S10的激发功率，P 2代表第二光线S20的激发功率，λ 2代表第二光线S20的光谱峰值，λ 3代表第三光线S30的光谱峰值。
本实施例中，第一光线S10和第二光线S20均为蓝光，然而第一光线S10也可以不是蓝光，而是其他色光，此时只需要根据该色光的波长更换色轮1061上涂覆的波长转换材料(荧光粉)即可，因该色光作为激发光激发荧光粉产生发射光，且入射光的波长需小于发射光，因此，该色光作为第一光线S10时其波长需要小于第三光线S30。例如：第一 光线S10为黄光，那么黄光作为激发光激发荧光粉后的发射光至少应为绿光或红光，也就需要色轮1061调整波长转换材料为接收黄光反射绿光或红光。并且，如果混合光线是白光，那么S20也需要做相应的调整，以配合第三光线S30混合形成白光。
请参阅图3，是本发明光源装置第一实施例多色色轮结构示意图。色轮1061为多色色轮。在色轮模组的色轮1061为多色色轮时，色轮1061根据波长转换材料的不同，划分出不同颜色区域。第一区域涂覆的荧光粉可被蓝光激发出红光，第二区域涂覆的荧光粉可被蓝光激发出绿光，而第三区域不涂覆荧光粉，直接将第一光线S10的蓝光的偏振方向转换后反射第一光线S10的蓝光，即将第一光线S10的p光转换为s光。相应的，滤光装置104改为区域镀膜的滤光片，一部分区域用于透射波长较短的蓝色p光、反射被色轮转换的波长较长的红色和绿色p光，一部分区域用于反射蓝色s光。
请参阅图4，是本发明光源装置第一实施例多色色轮转动角度与激光器电流值的关系图。如图4所示，色轮1061的转动角度θ与发射第一光线S10的激光器的电流A满足图中关系。其中，红光段C1和绿光段C2为第一光线S10的蓝光激发色轮1061上不同区域的荧光粉的时间，即第三光线S30发射的时间，蓝光段C3为第二光线S21或者第一光线S10入射到色轮1061第三区域Q3上反射的蓝光或者是二者的结合的时间，第一光线S10和第二光线S21是否结合，取决于第一光线S10和第二光线S20的激光器是否同时开启，如果发射第一光线S10的激光器没有开启，只开启第二光线S20的激光器，也可以同时开启发射第一光线 S10和第二光线S20的激光器，此处依据对光通量的实际要求进行调整。色轮1061转动时，每个颜色区域所占面积越大，发射光的时间越长。同时，激光器的电流A也可以进行调整，以进一步控制激光器在每个颜色区域内激发的时间长短。
基于多色色轮，各个颜色区域的光通量为Φ(i),i＝1,2,3,4…，i代表各个颜色区域。例如1代表红光，2代表绿光，3代表第一光线S10入射到色轮1061第三区域Q3上反射的蓝光，4代表第二光线S21的蓝光。x(i)和y(i)代表各颜色区域被激发后的发射光的色坐标。那么混合光的光通量Φ(W)和色坐标x(i)和y(i)满足以下关系：
Figure PCTCN2018088383-appb-000005
Figure PCTCN2018088383-appb-000006
Figure PCTCN2018088383-appb-000007
其中，W代表混合光线，i代表波长不同的每一第三光线S30，i＝1,2,3,4…，Φ(W)表示混合光线的光通量，x(W)和y(W)代表混合光线的色坐标的横坐标和纵坐标，Φ(i)表示每一第三光线S30的光通量，x(i)和y(i)表示每一第三光线S30的的颜色横坐标和颜色纵坐标。
光源模组101的激光器可以脉冲调制，因此入射各段颜色区域的第一光线S10的激发光的光通量均可以进行独立调节，且本实施例中，第二光线S21还可以进一步辅助调整混合光线的光通量。根据上述关系式， 改变任何颜色光的光通量最终都会影响到混合光线的光通量和色坐标。因此使得调节白光光通量和色坐标更加方便简单。
请参阅图5，是本发明光源装置第二实施例的结构示意图。如图5所示，本实施例与第一实施例的不同之处在于，本实施例光源装置1包括光源模组101、聚光透镜102a、第一聚光透镜组102b、第二聚光透镜组102c、分光装置103、反光装置105及色轮模组106。
光源模组101，用于发射偏振方向不同的第一光线S10和第二光线S20。分光装置103包括第一区域和第二区域，第一区域可用于反射第一光线S10，透射第二光线S20。反光装置105，可以接收被分光装置103透射的第二光线S20并将第二光线S20的偏振方向转换为与第一光线S10的偏振方向一致后(成为第二光线S21)反射至分光装置103的第一区域，并由分光装置103的第一区域将第二光线S21反射至出光口。色轮模组106，包括色轮1061和转轴1062，随着转轴1062的转动，固定在其上的色轮1061可随之转动。色轮1061上涂覆有波长转换材料，可以将第一光线S10转换为第三光线S30，并反射至分光装置103的第二区域并透射至出光口107。在出光口107汇合的第二光线S21和第三光线S30混合形成混合光线后输出。聚光透镜102a，设置在光源模组101和分光装置103之间，用于会聚光源模组101发射的光线；第一聚光透镜组102b设置在分光装置103和反光装置105之间，用于进一步会聚光线，第二聚光透镜组102c设置在色轮模组106与分光装置103之间，用于进一步会聚光线，第一聚光透镜组102b和第二聚光透镜组102c均包括三个聚光透镜。聚光透镜102a也可以替换为聚光透镜组， 第一聚光透镜组102b和第二聚光透镜组102c的透镜数量也可以根据实际需求进行增减。
所述光源装置1的工作原理描述如下：
光源模组101发射的第一光线S10被分光装置103的第一区域反射至色轮模组106，色轮模组106将第一光线S10的波长进行转换后形成第三光线S30，并反射第三光线S30至分光装置103的第二区域，分光装置103的第二区域再透射第三光线S30至出光口107。
同时，光源模组101发射的第二光线S20被分光装置103透射至反光装置105，由反光装置105将第二光线S20的偏振方向转换为与第一光线S10一致后，反射回分光装置103的第一区域，并被分光装置103反射至出光口107，与第三光线S30混合形成混合光线。
在本实施例中，光源模组101为激光模组，发射的第一光线S10和第二光线S20均为蓝色激光，而且二者的偏振方向相互垂直，第一光线S10为p光，第二光线S20为s光。分光装置103具体为偏光分光片，第一区域可透射s光，反射p光，第二区域可反射波长较短的光，透射波长较长的光，当激光模组发射第一光线S10和第二光线S20到偏光分光片后，第一光线S10(蓝色p光)被反射，第二光线S20(蓝色s光)被透射。
第一光线S10(蓝色p光)被分光装置103的第一区域反射后，到达色轮模组106的色轮1061上。本实施中，色轮1061为单色色轮，涂覆有波长转换材料，具体为黄色荧光粉，可将蓝光转换为黄光。因此当第一光线S10入射到色轮1061上后，成为激发光，激发色轮上的荧光 粉发出黄色的发射光，形成第三光线S30(黄色p光)。第三光线S30(黄色p光)被色轮1061反射到分光装置103的第二区域，此时，第三光线S30波长较长，(蓝光的波长范围为435-450nm，黄光的波长范围为577-597nm)，因此，分光装置103可透射第三光线S30至出光口107。第二光线S20被分光装置103的第一区域透射后，入射到反光装置105，该反光装置105具体为反蓝陶瓷片，可将第二光线S20(蓝色s光)转换为第二光线S21(蓝色p光)，即转换其偏振方向，其他光谱特性不变，并将第二光线S21反射回分光装置103的第一区域。此时，因为第二光线S21的偏振方向与第一光线S10的偏振方向一致，因此可被分光装置103的第一区域反射至出光口107。最后，第二光线S21(蓝色p光)和第三光线S30(黄色p光)，混合形成混合光线(白光)后成为照明光源从出光口107输出。
本实施例中，单色色轮可以替换为多色色轮，单色色轮和多色色轮的光通量的调节等与第一实施例相同，在此不再赘述。
请参阅图6，是本发明光源装置第三实施例的结构示意图。如图6所示，本实施例与第一实施例的不同之处在于，本实施例光源装置1包括光源模组101、分光装置103、反光装置105、色轮模组106、滤光装置、反射装置、聚光透镜102a、第一聚光透镜组102b、第二聚光透镜组102c。
光源模组101，用于发射偏振方向不同的第一光线S10和第二光线S20。分光装置103，用以反射第一光线S10，透射第二光线S20，反光装置105，以接收第二光线S20并将第二光线S20的偏振方向转换为与 第一光线S10的偏振方向一致后(第二光线S21)反射至分光装置103；色轮模组106，用以将第一光线S10转换为第三光线S30并反射至第一滤光装置108a；第一滤光装置108a，以透射第一光线S10，反射第三光线S30；第二滤光装置108b，以透射第三光线S30、反射转换偏振方向后的第二光线S21；反射装置包括第一反射装置109a、第二反射装置109b，第一反射装置109a用于反射第三光线S30至第二滤光装置108b、第二反射装置109b用于反射第二光线S21至第二滤光装置108b。第一聚光透镜组102b设置在分光装置103和反光装置105之间，用于进一步会聚光线，第二聚光透镜组102c设置在色轮模组106与分光装置103之间，用于进一步会聚光线，第一聚光透镜组102b和第二聚光透镜组102c均包括三个聚光透镜。聚光透镜102a也可以替换为聚光透镜组，第一聚光透镜组102b和第二聚光透镜组102c的透镜数量也可以根据实际需求进行增减。色轮模组106，包括色轮1061和转轴1062，随着转轴1062的转动，固定在其上的色轮1061可随之转动。色轮1061上涂覆有波长转换材料，可以将第一光线S10转换为第三光线S30，并反射至分光装置103。最后汇合的第二光线S21和第三光线S30混合形成混合光线后输出。
所述光源装置1的工作原理描述如下：
光源模组101发射的第一光线S10被分光装置103反射至第一滤光装置108a，再被第一滤光装置108a透射至色轮模组106，色轮模组106将第一光线S10的波长转换后形成第三光线S30(第三光线S30的波长大于第一光线S10)，并反射第三光线S30至第一滤光装置108a，由第 一滤光装置108a将第三光线S30反射到第一反射装置109a，第一反射装置109a再反射第三光线S30至第二滤光装置108b，由第二滤光装置108b透射第三光线S30至出光口107。
同时，光源模组101发射的第二光线S20被分光装置103透射至反光装置105，由反光装置105将第二光线S20的偏振方向转换为与第一光线S10一致后(转换成第二光线S21)，反射回分光装置103，并被分光装置103反射至第二反射装置109b，再由第二反射装置109b将第二光线S21反射至第二滤光装置108b，由第二滤光装置108b将第二光线S21反射至出光口107，与第三光线S30混合形成混合光线。
在本实施例中，光源模组101为激光模组，发射的第一光线S10和第二光线S20均为蓝色激光，而且二者的偏振方向相互垂直，第一光线S10为p光，第二光线S20为s光。分光装置103具体为偏光分光片，可透射s光，反射p光，当激光模组发射第一光线S10和第二光线S20到偏光分光片后，第一光线S10(蓝色p光)被反射，第二光线S20(蓝色s光)被透射。第一滤光装置108a可透射波长较短的光，如蓝光，透射波长较长的光，如黄光；第二滤光装置108b正好与第一滤光装置108a相反，可透射波长较长的光，如黄光，可反射波长较短的光，如蓝光。第一反射装置109a和第二反射装置109b为全反射镜，可以反射接收到的任何光线。
第一光线S10被分光装置103反射后，到达第一滤光装置108a。第一光线S10(蓝色p光)，透过第一滤光装置108a，入射到色轮模组106的色轮1061上。本实施中，色轮1061为单色色轮，涂覆有波长转换材 料，具体为黄色荧光粉，可将蓝光转换为黄光。因此当第一光线S10入射到色轮1061上后，成为激发光，激发色轮上的荧光粉发出黄色的发射光，形成第三光线S30(黄色p光)。第三光线S30(黄色p光)的波长较长，因此，第三光线S30被色轮1061反射至第一滤光装置108a后再被反射到第一反射装置109a，本实施例中，反射装置为全反射镜，全反射镜将第三光线S30反射到第二滤光装置108b，因其波长较长，可被第二滤光装置108b透射至出光口107。
同时，第二光线S20被分光装置103透射后，入射到反光装置105，该反光装置105具体为反蓝陶瓷片，可将第二光线S20(蓝色s光)转换为第二光线S21(蓝色p光)，即转换其偏振方向，其他光谱特性不变，并将第二光线S21反射回分光装置103。此时，因为第二光线S21的偏振方向与第一光线S10的偏振方向一致，因此可被分光装置103反射至第二反射装置109b，第二反射装置109b将第二光线S21反射到第二滤光装置108b，因第二滤光装置108b可以反射波长较短的光，因此第二光线S21(蓝色s光)被反射至出光口107，与第三光线S30混合形成混合光线(白光)后成为照明光源从出光口107输出。
本实施例中，单色色轮可以替换为多色色轮，单色色轮和多色色轮的光通量的调节等与第一实施例相同，在此不再赘述。
请参阅图7，是本发明的投影装置的结构示意图。本发明的光源装置1可用于投影设备，也可用于照明设备。所述投影装置2包括上述光源装置1，所述投影装置2的其他器件及功能与现有投影装置的器件及功能相同，在此不再赘述。
本发明所述光源装置通过将光源模组分为第一光线和第二光线，使第一光线用于激发波长转换材料以形成其他色光，使第二光线作为补偿光与第一光线混合形成混合光线，通过调节第一光线和/或第二光线的激发功率达到调整混光的光通量、色温的目的，解决了目前混合形成白光的光通量和色温无法调整的问题。
以上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。
