Description
本实用新型涉及光学技术领域，特别是涉及一种波长转换装置、光源系统以及投影装置。
随着显示技术的发展，人们对于显示画质的要求越来越高，光源的颜色色域越大，显示画面可显示的颜色越多，越接近物体自然的颜色。目前的投影光源，经常采用荧光色轮来提供彩色光序列。其中，将荧光色轮的不同色段轮流且周期性设置于激发光的传播路径上，进而利用激发光来激发荧光色轮的不同色段上的荧光材料，以产生不用颜色的荧光。
然而，由于荧光材料所产生的光谱范围较宽，使得部分荧光的色纯度不足，进而导致光源的色域不够大。在这种情况下，一般需要通过滤光片来对荧光进行过滤，以提高荧光的色纯度，这样光效损失很大。
因此，需要提供一种波长转换装置、光源系统以及投影装置，兼顾高光效的同时，提高色纯度。
本实用新型主要解决的技术问题是提供一种波长转换装置、光源系统以及投影装置，可以在兼顾高光效的同时，提高色纯度。

优选地，所述第一子波长转换装置包括设置有黄色荧光粉材料的第一波长转换区、设置有反射粒子的第一反射区、设置有反射粒子的第二反射区；所述第二子波长转换装置包括与所述第一波长转换区、第一反射区及第二反射区相对应设置的具有红光量子点材料的第一峰宽修饰区、具有绿光量子点材料的第二峰宽修饰区、透光区。
优选地，所述第一子波长转换装置包括设置有黄色荧光粉材料的第一波长转换区、第一透光区、第二透光区；所述第二子波长转换装置包括与所述第一波长转换区、第一透光区及第二透光区相对应设置的具有红光量子点材料的第一峰宽修饰区、具有绿光量子点材料的第二峰宽修饰区、透光区。
进一步地，所述第一子波长转换装置还包括设置有绿色荧光粉材料的第二波长转换区；所述第二子波长转换装置还包括设置有黄光量子点材料的第三峰宽修饰区，所述第二波长转换区与所述第三峰宽修饰区相对应设置。
优选地，所述黄色荧光粉材料是YAG:Ce3+，M2SiO4:Eu2+(M=Ca,Sr,Ba)荧光粉中的至少一种；所述绿色荧光粉材料是LuAG:Ce3+,β-Sialon:Eu2+，M2SiO4:Eu2+(M=Ca,Sr,Ba)荧光粉中的至少一种；所述反射粒子为TiO2，Al2O3中的至少一种；所述量子点材料为含Cd类量子点CdSe/ZnS、CdSe/CdZnS中的一种，或者为无Cd类量子点
CuInS2/ZnS。 通过选择不同粒径的量子点可以得到所需要的红光、黄光和绿光。
所述波长转换区和反射区可以采用硅胶荧光粉膜片、发光玻璃或者发光陶瓷；所述峰宽修饰区可以采用硅胶与量子点混合热固化形成。
优选地，所述第一透光区、第二透光区以及第二子波长转换装置中的透光区均具有扩散光的作用，可以采用散射硅胶粉片。
所述散射硅胶粉片是将白色漫反射粒子和硅胶混合均匀后固化形成。
优选地，所述第一峰宽修饰区的量子点材料表面设置有第一滤光膜，所述第一滤光膜允许小于预定角度的第一波长转换区的出射光透射，大于预定角度的第一波长转换区的出射光反射，并反射与第一波长转换区出射光波长不同的其他色光。

进一步地，所述驱动装置为具有一转动轴的转动装置，所述两个环状结构同轴固定于所述转动轴上。
优选地，所述第一子波长转换装置中的各个区域与其所对应设置的所述第二子波长转换装置中的各个区域相对所述两个环状结构的中心呈特定角度设置，所述引导元件设置成使得所述激发光在所述第一子波长转换装置上形成的光斑与所述第一输出光在所述第二子波长转换装置上形成的光斑相对所述两个环状结构的中心也呈所述特定角度设置。
优选地，所述特定角度为0度或180度。
优选地，所述引导元件包括至少一反射装置，所述反射装置对所述第一输出光序列进行反射，以改变所述第一输出光序列的传播方向，所述反射装置为平面反射装置或者为呈半椭球状或呈半球状且光反射面朝内的反射装置。
进一步地，所述平面反射装置包括二向色镜或反射镜。
进一步地，所述呈半椭球状或呈半球状且光反射面朝内的反射装置上设置有入光口，所述激发光经所述入光口入射到所述波长转换装置。
优选地，所述第一子波长转换装置为一筒状结构，所述第二子波长转换装置为一环状结构，并与所述筒状结构同轴固定；所述第一子波长转换装置的各个区域设置于所述筒状结构的外侧壁，所述第二子波长转换装置的各个区域设置于所述环状结构上，且位于所述筒状结构的外侧。

本实用新型提供的波长转换装置、光源系统以及投影装置较现有技术具有以下有益效果：
1、该波长转换装置中荧光粉材料和量子点材料协同作用，利用荧光粉材料吸收蓝光转换成较长波长荧光，再经过量子点材料转换成更长波长荧光；其中荧光粉层吸收大部分蓝光，由于荧光粉热稳定性一般较高，能够承受较高光功率密度的辐照，而量子点层只吸收比其发射波长稍短的荧光，而且激发量子点层的光斑直径较激发荧光粉层光斑稍大，所以该波长转换装置的结构可以大大减少热效应。
2、量子点材料能够吸收绝大部分荧光层发出的荧光，转化效率高；而且量子点材料的发射峰很窄，可以代替修饰片使用，在保证高光效的基础上，提高色纯度。
3、量子点材料的余辉时间一般在几个纳秒，而目前荧光粉的余辉时间在几十至几百个纳秒，量子点材料相比于荧光粉更不容易出现发光饱和，因而能够实现高亮度的荧光发射。

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、波长转换装置以及匀光装置109；其中波长转换装置包括第一子波长转换装置
106、第二子波长转换装置 107及驱动装置 108。
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为一蓝色激光器或者蓝色发光二极管，以产生蓝光激发光。
如图 2所示，第一子波长转换装置
106为一环状结构，至少包括第一波长转换区。在本实施例中，第一子波长转换装置
106包括绕其环状结构的周向分段设置的具有黄色荧光粉的第一波长转换区、具有反射粒子的第一反射区、具有绿色荧光粉的第二波长转换区以及具有反射粒子的第二反射区。上述荧光粉材料能够将入射到其上的蓝色激发光波长转换成相应颜色的受激光。具体来说，黄色荧光粉将入射到其上的蓝色激发光转换成黄色受激光，绿色荧光粉将入射到其上的蓝色激发光转换成绿色受激光。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；同时，第一子波长转换装置还包括设置有反射粒子的第一反射区和第二反射区，蓝色激发光从上述第一反射区和第二反射区的出射方向与激发光相对上述反射区的入射方向相反。
其中，上述黄色荧光粉是YAG:Ce3+，M2SiO4:Eu2+(M=Ca,Sr,Ba)荧光粉中的至少一种；上述绿色荧光粉是LuAG:Ce3+,β-Sialon:Eu2+，M2SiO4:Eu2+(M=Ca,Sr,Ba)荧光粉中的至少一种；上述反射粒子为TiO2，Al2O3中的至少一种；上述波长转换区和反射区可以采用硅胶荧光粉膜片、发光玻璃或者发光陶瓷。
如图 2所示，第二子波长转换装置 107为一环状结构，其与第一子波长转换装置
106同轴固定，且具体设置于第一子波长转换装置 106的环外侧。在其他实施例中，第二子波长转换装置 107也可以设置于第一子波长转换装置
106的环内侧。第二子波长转换装置 107至少包括第一峰宽修饰区。在本实施例中，第二子波长转换装置
107包括绕其环状结构的周向分段设置的具有红光量子点的第一峰宽修饰区、具有绿光量子点的第二峰宽修饰区、具有黄光量子点的第三峰宽修饰区以及透光区。上述各个区域与第一子波长转换装置
106上的各颜色的波长转换区对应设置。在本实施例中，第一子波长转换装置106上的各个区域与第二子波长转换装置 107对应设置的各个区域相对环状结构的中心成
180度设置，具体的，第一波长转换区域与第一峰宽修饰区、第一反射区与第二峰宽修饰区、第二波长转换区域与第三峰宽修饰区、第二反射区与透光区相对环状结构的中心成180度设置。本实用新型中关于各个区域的设置方式以此类推。
其中，上述量子点材料可以选自含Cd类量子点CdSe/ZnS、CdSe/CdZnS中的一种，或者选自无Cd类量子点 CuInS2/ZnS。
通过选择不同粒径的量子点可以得到所需要的红光、黄光和绿光。所述峰宽修饰区可以采用硅胶与量子点材料混合热固化形成。所述透光区均具有扩散光的作用，可以采用散射硅胶粉片。本实用新型中的所有透光区都优选具有光扩散的作用。
所述散射硅胶粉片是将白色漫反射粒子和硅胶混合均匀后固化形成。所述白色漫反射粒子用于对入射光进行散射，一般为盐类或者氧化物类粉末，例如硫酸钡粉末、氧化铝粉末、氧化钛粉末、氧化锆粉末等。
上述峰宽修饰区采用而量子点材料，是因为量子点的发光半峰宽约为20~30nm，色纯度较高；相较于荧光粉，虽然荧光粉的稳定性很高，但是荧光粉的半峰宽很高，氮化物红色荧光粉的半峰宽大约是80~90nm。所以使用量子点材料可以提高色纯度，但是量子点的热稳定性相对较低，阻碍了其在高功率密度光源上的应用，本实施例的光源系统利用荧光粉材料吸收蓝光转换成较长波长荧光，再经过量子点材料转换成更长波长荧光，其中，量子点层只吸收比其发射波长稍短的荧光，能量密度较低，而且激发量子点层的光斑直径较激发荧光粉层光斑稍大，且外环直径较大也相应增加了散热面积，所以这种应用方式可以大大减少热效应，提高色纯度。
当然，第一子波长转换装置106上的各个区域与第二子波长转换装置
107对应设置的各个区域也可以相对环状结构的中心成其他角度设置。
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。第一子波长转换装置
106与第二子波长转换装置 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所产生的蓝色激发光经二向色镜
102透射，经透镜 103进行聚光后入射到第一子波长转换装置 106上，并在第一子波长转换装置 106上形成如图 2所示的光斑 101A。第一子波长转换装置
106和第二子波长转换装置 107在驱动装置 108的驱动下同步转动，进而使得第一子波长转换装置 106上的各个区域与第二子波长转换装置
107上的各个区域同步转动。在第一子波长转换装置 106和第二子波长转换装置 107的转动过程中，第一子波长转换装置
106上的各个波长转换区及反射区依次且周期性设置于激发光光源
101所产生的蓝色激发光的传播路径上，使得蓝色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，蓝色激发光被各个反射区反射，并经透镜
103和 105以及二向色镜 102和反射镜 104所组成的引导元件导引后入射到第二子波长转换装置 107，形成如图 2所示的光斑 101B。
在引导元件中，透镜 103和
105分别用于对受激光和反射的蓝色激发光进行收集和聚光，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，以改变受激光和经反射区反射的蓝色激发光的传播方向。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呈 45度设置。在本实施例中，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相对第一子波长转换装置 106和第二子波长转换装置
107的环状结构的中心呈 180度设置。
此时，由于第一子波长转换装置 106与第二子波长转换装置 107相对固定，并且第一子波长转换装置
106与第二子波长转换装置 107上对应设置的各个区域同样相对第一子波长转换装置 106与第二子波长转换装置 107的环状结构的中心呈
180度设置且同步转动，因此可以确保由第一子波长转换装置 106的各个区域作用的出射光经二向色镜 102和反射镜 104作用后入射到第二子波长转换装置
107上相应设置的区域上，进而得到高色纯度的输出光。经第二子波长转换装置 107作用得到的输出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，第一子波长转换装置 106和第二子波长转换装置
107相对固定并由同一驱动装置同步驱动，同时利用引导元件将两个子波长转换装置中对应设置的各个区域进行同步，具有结构简单、易于实现以及同步性高等优点。此外，引导元件的各元件相对激发光光源保持静止，避免了随第一子波长转换装置
106和第二子波长转换装置 107转动，因此其光学稳定性更高。
在本实施例中，为了减少红光量子点材料界面的反射，红光量子点材料段可以采用0°yellowpass+红光量子点材料结构，其中经过第一子波长转换装置转换的黄光透过0°yellowpass再激发红光量子点材料发射红光，在红光量子点材料界面反射的黄光和红光在0°yellowpass界面继续反射回去，提高黄光利用率，增加红光出光效率。同样，在黄光量子点材料段可以使用0°greenpass+黄光量子点材料，绿光量子点材料段使用0°bluepass+绿光量子点材料，而第二子波长转换装置的透光区则直接使用0°bluepass+散射硅胶粉片。通过这样的结构，可以实现将量子点材料应用于大功率蓝光光源上，并同时兼顾高色纯度和高光效。
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，第一子波长转换装置
106上的波长转换区可以是具有黄色荧光粉的第一波长转换区、具有绿色荧光粉的第二波长转换区中的一个或两个的任意组合，反射区可以设置一个或者两个。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所需数量的反射区。此时，第二子波长转换装置
107上的区域设置则根据第一子波长转换装置106上的各个区域所产生的受激光的波长进行相应配置，本实用新型对此并不作限制。
请参见图 3，图 3是本实用新型光源系统的第二实施例的结构示意图。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，第一子波长转换装置 206在将激发光光源
201产生的激发光波长转换成受激光后透射该受激光，反射区替换为透光区。经第一子波长转换装置 206透射的受激光或激发光经透镜 203和 205以及反射镜
202以及 204所组成的引导元件导引后入射到第二子波长转换装置 207相对应的各个区域，并经各个区域作用后入射到匀光装置 209。
此外，在第一子波长转换装置 206还可以只设置一个透光区，该透光区周期性设置于激发光光源
201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 203和 205以及反射镜 202以及
204所组成的引导元件沿着与受激光相同的光路导引到第二子波长转换装置
207上的透光区，进行透射；而第二子波长转换装置中不再设置具有黄光量子点的区域，通过该波长转换装置得到的输出光是只含有红、绿、蓝三基色的输出光序列。
请参见图 5，图 5是本实用新型光源系统的第三实施例的结构示意图。本实施例的光源系统 300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 301产生的激发光由复眼透镜 303和 304以及聚焦透镜 305进行聚光后经反射装置
302的入光口入射到波长转换装置 306。经第一子波长转换装置 306反射的受激光或激发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
302反射到第二子波长转换装置 307。经第二子波长转换装置 307作用的受激光进一步入射到锥形导光棒 309。其中，当反射装置 302呈半椭球状时，反射装置
302能够将来自反射装置 302的一个焦点附近的受激光或激发光反射到反射装置 302的另一个焦点附近。当反射装置
302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
302大致也可以把其中一对称点的受激光或激发光反射到另一对称点。此外，在其他实施例中，反射装置 302可以不设置入光口，此时激发光光源 301与反射装置
302分别设置于第一子波长转换装置 306的两侧。激发光光源 301产生的激发光可照射到第一子波长转换装置 306后所产生的受激光进一步透射到反射装置
302上。
值得注意的是，在反射装置 302的反射作用下，激光光光源 301所产生的激发光在第一子波长转换装置
306上产生的光斑与受激光或激发光在第二子波长转换装置 307上产生的光斑相对于第一子波长转换装置 306和第二子波长转换装置 307的环状结构的中心呈
0度设置，因此在第一子波长转换装置 306和第二子波长转换装置 307上相对应设置的各个区域也需要相对于第一子波长转换装置 306和第二子波长转换装置
307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，可以调整激发光在第一子波长转换装置
306上产生的光斑与受激光在第二子波长转换装置 307上产生的光斑相对第一子波长转换装置 306和第二子波长转换装置
307的环状结构的中心呈任意角度设置，因此使得第一子波长转换装置 306和第二子波长转换装置 307上的相对应设置的各个区域相对于第一子波长转换装置
306和第二子波长转换装置 307的环状结构的中心呈任意角度设置。
请参见图 6，图 6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
5所示的光源系统 300不同之处在于，第一子波长转换装置 406与第二子波长转换装置 407由支架 408同轴固定，且沿轴向间隔设置。在第一子波长转换装置
406与第二子波长转换装置 407之间设置一锥形导光棒 409。激发光光源 401产生的激发光由复眼透镜 403和 404以及聚焦透镜
405进行聚光后经反射装置 402的入光口入射到第一子波长转换装置 406。经第一子波长转换装置 406反射的受激光或激发光入射到反射装置
402并进行反射。经反射装置 402反射的受激光或激发光首先进入导光棒 409，导光棒 409对受激光及激发光进行收集，以减小受激光及激发光的发散角。经导光棒
409导光后的受激光或激发光入射到第二子波长转换装置 407上，使得受激光或激发光在第二子波长转换装置
407上的入射角度较小，提高了转换效率。在本实施例中，导光棒 409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，第一子波长转换装置
406如果是透射型，反射装置 402可以省略，此时受激光或激发光直接经第一子波长转换装置 406透射到导光棒 409。
请参见图 7，图 7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，本实施例的第一子波长转换装置 506呈筒状结构，波长转换区和反射区设置于该筒状结构的外侧壁上。本实施例的第二子波长转换装置
507为环状结构且与该筒状结构同轴固定。第一子波长转换装置 506和第二子波长转换装置 507进一步同轴固定于驱动装置 508的转动轴上，并在驱动装置
508的驱动下同轴且同步转动。
在本实施例的光源系统 500的工作过程中，激发光光源 501所产生的激发光经二向色镜
502透射，并经透镜 503进行聚光后入射到第一子波长转换装置 506的外侧壁上。第一子波长转换装置
506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；反射区反射激发光。经第一子波长转换装置 506反射的受激光或激发光经透镜 503和
504以及二向色镜 502所组成的引导元件导引后入射到第二子波长转换装置 507。第二子波长转换装置 507上的峰宽修饰区和透光区设置于第一子波长转换装置
506的筒状结构的外侧，进而可以接收到受激光或激发光并对受激光或激发光作用后提高色纯度。经第二子波长转换装置 507作用后得到的输出光序列进一步入射到匀光装置
509，以进行匀光处理。在其他实施例中，第一子波长转换装置 506也可以将受激光透射到第二子波长转换装置 507上。
请参见图 8和图 9，图 9是本实用新型光源系统的第六实施例的结构示意图，图 9是图
8所示的光源系统中的波长转换装置的主视图。本实施例的光源系统 600与图 3和图 4所示的光源系统 200不同之处在于，本实施例的第一子波长转换装置
606和第二子波长转换装置 607为首尾相连的两个带状结构，各个区域并排设置于该两个带状结构上。在本实施例中，第一子波长转换装置
606进一步包括并排且从上到下依序设置的具有黄色荧光粉的第一波长转换区、第一反射区、具有绿色荧光粉的第二波长转换区以及第二反射区，第二子波长转换装置
607则包括并排且从上到下依序设置的具有红光量子点的第一峰宽修饰区、具有绿光量子点的第二峰宽修饰区、具有黄光量子点的第三峰宽修饰区以及透光区。
在第一子波长转换装置 606和第二子波长转换装置
607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，以使得第一子波长转换装置
606上的第一波长转换区、第一反射区、第二波长转换区以及第二反射区周期性设置于激发光光源
601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，而第一反射区和第二反射区则反射入射到其上的蓝光激发光。经第一子波长转换装置
606反射后的受激光或激发光经透镜 603和 605、二向色镜 602以及反射镜 604所组成的引导元件导引后入射到第二子波长转换装置
607上的相应区域，经各峰宽修饰区和透光区作用后出射，并共同入射到匀光装置 609，以进行匀光处理。本实施例的第一子波长转换装置 606和第二子波长转换装置
607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光源系统中的第一子波长转换装置和第二子波长转换装置形成的波长转换装置以及使用上述光源系统的投影装置。
综上所述，本实用新型的波长转换装置及光源系统使用波长稍短的荧光激发量子点材料转换成波长稍长的荧光，从而大大减少量子点材料直接被蓝光激发而产生的热量，转换效率高；同时量子点材料发光半峰宽窄，色纯度较高，兼具高光效和高色纯度的优点。
以上所述仅为本实用新型的实施例，并非因此限制本实用新型的专利范围，凡是利用本实用新型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，均同理包括在本实用新型的专利保护范围内。
