 本发明的实施方式
本实用新型通过在基板的两侧安装缓冲层，来实现对色轮的基板的缓冲。
为了使本实用新型的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本实用新型进行进一步详细说明。
结合图1至图5进行说明，本实用新型提出第一实施例，本实用新型一种色轮固定装置，其包括固定件1、第一缓冲层2、第二缓冲层4和马达5。其中：
（1）第一缓冲层2和第二缓冲层4分别位于基板3的两侧的表面上。固定件1与所述第一缓冲层2之间通过胶连接；马达5与第二缓冲层4之间通过胶连接。也即第一缓冲层2的上表面可与固定件1胶连接，和/或，第二缓冲层4的下表面可与马达5的上表面胶连接。本技术方案，采用胶连接方式来连接相互接触的部件，可以使得各部件的连接更紧密，从而起到更好的缓冲作用。
优选的，第一缓冲层2为硅胶垫或橡胶垫，如图1、图2所示；优选的，第一缓冲层2为弹簧，如图3至图5所示。优选的，第二缓冲层4为硅胶垫或橡胶垫，如图1至图3所示；优选的，第二缓冲层4为弹簧，如图4和图5所示。由于基板工作时，产生大量的热，本技术方案中的缓冲层可以快速传导基板产生的热量，从而可以起到散热的作用。另外，硅胶垫或橡胶垫的一面或两面附着胶，这样可以与基板连接更牢固，可以有效防止基板工作时松动而被震破裂。
所述缓冲层的大小无特殊限制，当增大缓冲层与色轮的接触面积时，可以使得基板的温度更快的传递到缓冲层，提高基板散热的速度。
（2）所述第一缓冲层2、基板3和第二缓冲层4均设有中通孔6。其中，所述三个中通孔6的大小相同。该中通孔6的形状无特殊限制，该中通孔6可以使第一缓冲层2、基板3和第二缓冲层4耦合在转轴51即可。优选的，中通孔6的形状与转轴51的截面形状相同。进一步优选的，中通孔6横截面的形状包括但不限于齿轮形、椭圆形、矩形、不规则形状，利用上述形状的中通孔6，可以使第一缓冲层2、基板3和第二缓冲层4紧密的连接而不会晃动。
（3）所述马达5包括转轴51，转轴51依次穿过第一缓冲层2、基板3和第二缓冲层4的中通孔6。
（4）所述固定件1将第一缓冲层2、基板3和第二缓冲层4顺序固定在马达5上。其中，优选的，固定件设有凹槽或通孔，转轴51的末端插入凹槽（如图3所示）或通孔（如图1、图2、图4所示）内而将固定件固定，固定件与转轴的此种连接方式，使得安装的时候更方便。优选的，固定件和转轴上设有相适配的内螺纹和外螺纹，二者通过螺纹装配连接。固定件也可通过螺钉固定在转轴上。通过该技术方案将固定件固定在转轴上，可以使得固定件和转轴固定更加牢固。
本实施例中，色轮的基板3可以为金属基板或者合金基板，也可以为玻璃基板或这陶瓷基板。优选的，基板3为玻璃基板或陶瓷基板，由于玻璃或陶瓷的耐热性好、且玻璃或陶瓷中各组份的热膨胀系数差异小，可以有效防止基板受热时破裂。
上述技术方案中，第一缓冲层2和第二缓冲层4分别位于基板3的两侧，能够起到减震的作用以防止基板破裂。另外，当基板处在光路中时，由于其工作会产生大量的热量，所述缓冲层与基板直接接触可以起到散热的作用。
结合图6和图7，本实用新型提出第二实施例，一种色轮组件，其包括第一实施例中所述的色轮固定装置1和基板，基板位于色轮装置1的第一缓冲层和第二缓冲层之间。所述基板上设有波长转换材料22的分区21。所述分区21的个数无特殊限制，优选为三个分区21。所述分区21中可覆有波长转换材料22，也可不覆有波长转换材料22，优选的，至少一个分区21覆有波长转换材料22。优选的，所述分区21位于基板的外圆周上，且不与第一、第二缓冲层所覆盖的基板表面部分重叠，从而不影响外部光源组件发出的光对该分区21上波长转换材料22的照射。所述具有分区21且分区21上覆有波长转换材料22的基板被称作色轮2。本实施例中，所述缓冲层和基板之间的连接方式无特殊限制，例如：基板可以直接被第一缓冲层和第二缓冲层紧压在中间。优选的，所述第一缓冲层和基板之间、第二缓冲层和基板之间通过胶连接，该连接可以有效防止基板和缓冲层之间有间隙而产生滑动而导致基板在振动下破裂。
本实用新型中的波长转换材料22可以为滤光薄片或荧光粉。本实用新型的色轮2通过色轮固定装置固定，不仅可以防止在色轮组件工作时色轮的破损，还可以使得色轮的热量迅速传递给色轮固定装置实现快速降温的效果。
本实用新型提出第三实施例，结合图8进行说明。一种投影系统包括光源组件1和第二实施例中的色轮组件2，所述色轮组件2的基板上载有波长转换材料的分区位于所述光源组件1所发出的光的光路上，用于对所述发出的光进行波长转换。所述光源组件1可包括激发光源。色轮组件2可包括色轮、滤光片和色轮固定装置，其中，激发光源的出射光先经过滤光片，再到达色轮，色轮通过对光进行波长转换，出射出射光。当光达到色轮经过波长转换，会产生大量的热，色轮固定装置与色轮紧密接触，可以迅速传导色轮上的热量，从而可以提高色轮散热的效率。同时色轮固定装置通过缓冲层将色轮固定，高速旋转时产生对色轮振动的缓冲，从而使得色轮的使用寿命更长。
以上所述仅为本实用新型的优选实施例，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者直接、间接运用在其他相关的技术领域，均视为包括在本实用新型的专利保护范围内。
