Description

一种色轮模组 【技术领域】
本申请涉及数字投影技术领域，尤其涉及一种色轮模组。
【背景技术】
色轮是研究颜色相加混合的一种实验仪器，而对于投影设备而言，色轮是分离和处理色彩的必备部分。投影设备中的光源模组包括激发光源和位于该激发光源光路上的色轮，投影机色轮的工作原理为将透过白光进行分色，并通过高速马达使其转动，然后顺序分出不同单色光于指定的光路上，最后经由其它光机元件合成并投射出全彩影像，具体为当激发光源发射的激光照射到色轮上时，色轮上的波长转换材料(如荧光粉)会吸收激发光并产生波长不同的受激发光束，同时色轮上的驱动装置会驱动色轮高速旋转，以使激发光照射到色轮不同区域的荧光粉上发出不同颜色的受激光束，如红色受激光束、绿色受激光束和蓝色受激光束，这些不同颜色的受激光束可合成进行图像投影显示的一束合成光束。
实现本申请过程中，申请人发现相关技术中至少存在如下问题：在波长转换材料吸收激光的过程中，激光的部分能量会被转换成热量，且该热量会被色轮的表面材料吸收，从而引起波长转换材料温度升高，激发效率降低。另外，色轮在高速旋转时会吸附周围空气中的粉尘，而粉尘的附着会使波长转换材料的激发效率降低。目前，色轮的防尘与散热的解决办法基本都是将色轮整个密封起来，利用内部的气流扰动进行热交换，将热导出至外壳，以达到降温的目的。如果只依靠色轮对气流的扰动进行散热，在功率较大的时候，会导致色轮过热。因此，如何在保证色轮防尘效果的前提下，提高色轮的散热效果，成为本技术领域人员急需解决的难题。

需要说明的是，附图中标注的虚线仅为了阐述本申请产品的结构之间的连接和划分关系，便于本领域的技术人员更好的理解本申请的技术方案，而不能理解为指示或者暗示应用本申请的技术方案的产品含有虚线或者其他内部不可视结构。
请参见图1，色轮模组100包括外壳1、隔板2以及色轮3，外壳1设置有收容空间10，所述收容空间10划分有色轮安装空间101、连接空间102和冷却空间103。
所述外壳1起到密封的作用，防止外部的粉尘以及颗粒物进入到色轮3中，理想状态下需达到完全封闭，在本实施例中，外壳1采用轻薄、防水、耐高温、强度较大的金属、陶瓷或者塑型材料，为了利于激光能够穿透壳体入照射到波长转换层上，且波长转换层产生的受激光能够穿透壳体出射，应当保持激发光源到所述色轮3的光路是畅通的，至少在外壳1上设置一个通光孔用于入射激发光和/或出射受激发光，所以外壳 1至少与色轮3相对应的区域采用的透明的材料，外壳1还可以是全透明材料制成。为了保证良好的防尘效果，外壳1通常采用一体成型的方式，还可以采用螺丝固定并加上密封圈密封的组合方式。
所述隔板2设置于所述连接空间102，并且将所述连接空间102分割成第一气流通道4和第二气流通道5，其中，所述第一气流通道4分别与色轮安装空间101和冷却空间103连通，所述第二气流通道5分别与色轮安装空间101和冷却空间103连通，所述色轮安装空间101、第一气流通道4、冷却空间103和第二气流通道5闭合形成气流回路。在本实施例中，所述隔板2的一端靠近色轮3，所述连接空间102大致位于所述安装空间101和所述冷却空间103之间，设置于所述连接空间102的所述隔板2把所述连接空间102分割成左右两部分，分别为第一气流通道4和第二气流通道5，可以理解，在空间的延伸上，收容空间10亦被分割成左右两个区域，图中标注的虚线的走向代表了气流循环的方向，两侧的沿虚线方向的气体流动形成了一个闭合的气流回路。
所述色轮3安装于所述色轮安装空间101，所述色轮3包括：基板31，其一表面S1覆盖有波长转换层(图中未示出)；风扇叶片组32，设置于所述基板31；驱动装置33，与所述外壳1的内表面相固定，并且所述驱动装置33的转动轴与所述基板31相固定，用于驱动所述基板31转动。在本实施例中，色轮3为反射式色轮，基于此，外壳1与基板31平行的一侧表面设置有通光孔，此时，激光从通光孔进入外壳内部，并且，受激光也从该通光孔出射，当然，本申请不限于此，在一些实施例中，色轮3也可以为透射式色轮，相应的，外壳1与基板31平行的两个侧面分别设置一个通光孔，即外壳1有前后对称的通光孔，此时，激发光从外壳1其中一个通光孔进入(比如外壳1前侧通光孔)，受激光从外壳1的另一个通光孔出射(比如外壳1后侧通光孔)。
基板31为圆形铝合金盘，在一些实施例中，基板31的形状以及材 料可以依据实际需求设置。在本实施例中，所述基板31的正表面为S1，与正表面S1相对应的背面为S2，所述正表面S1平行于外壳1的内壁且与面对设置有通光孔的外壳1一侧，正表面S1覆盖有波长转换层，所述波长转换层用于经激发光照射后产生受激发光，所述波长转换层是在所述正表面S1上均匀覆盖一层具有一定厚度的波长转换材料，最常用的波长转换材料是荧光粉，例如钇铝石榴石(YAG)荧光粉，它可以吸收蓝光并受激产生黄色的受激光。波长转换材料还可能是量子点、荧光染料等具有波长转换能力的材料，并不限于荧光粉。多数情况下，波长转换材料往往是粉末状或者颗粒状的，难以直接形成波长转换层，此时就需要使用一种粘接剂把各个波长转换材料颗粒固定在一起，并形成波长转换层，如片状层。所述波长转换材料含有不同色段上的光波长转换材料，照射到波长转换层的激光会被波长转换材料吸收，初始的激光经过一系列变化产生波长不同的受激光束。在一些实施例中，为了防止波长转换层在基板转动的过程中甩脱，所述波长转换层可以包括依次层叠固定的陶瓷基板、反射层以及荧光粉层，所述波长转换层外可以依次包围透光层、粘接层以及外胶层。
所述风扇叶片组32固定于所述基板31远离设置有波长转换层的另一表面S2。色轮3转动时，风扇叶片组32带动气流流动，在隔板2两侧形成一个闭合的气流回路，把来自色轮3的波长转换层的热空气从色轮3所在的热风区引流到外壳1内远离色轮3的冷风区，使色轮3产生的热量在冷风区通过热传导释放到空气中，实现在外壳1全封闭状态下，色轮3与外部空气之间的热交换。可以理解的是，在波长转换材料吸收激光的过程中，激光的部分能量会被转换成热量，且该热量会被色轮的表面材料吸收，从而引起波长转换材料温度升高，所以，色轮安装空间101的波长转换层附近为热风区，相应的，远离色轮1的冷却空间103为冷风区。
在本实施例中，所述风扇叶片组32与所述基板31一体成型，也可采用其他具体可行的连接或者固定关系，比如螺丝固定、焊接和粘接等，风扇叶片与基板面固定连接即可，贴合或者不贴合基板面均可。所述风扇叶片组12具有两个或者两个以上的风扇叶片，所述风扇叶片组32绕着所在面环形设置，通过这种设置的风扇叶片有效地增大了换热面积。值得注意的是，在本实施例中，所述风扇叶片的形状和片数并不限于实施例图中所示的方式，风扇叶片的片数优选奇数片，最好为3片或者5片，均衡的设置于基板31面上，风扇叶片形状可以是鸟翼型或者直角梯形状等等，风扇叶片的制备材料可以是塑料或者金属等密度小、散热快的材料。
所述驱动装置33与所述外壳的内表面相固定，并且所述驱动装置33的转动轴与所述基板31相固定，用于驱动所述基板31转动。进一步的，所述驱动装置33与所述外壳的内表面相固定，并且所述驱动装置33的转动轴与所述基板31相固定，固定的方式可以是一体成型、焊接、螺纹咬合等，所述驱动装置33(比如电机)上电时，转动轴跟随驱动装置33转动，转动轴的转动带动所述基板31转动，那么，固定在所述基板31上的风扇叶片组32同步旋转，风扇叶片组32同步旋转速度取决于驱动装置33设定的速率，所述驱动装置33设定的速率可以设置成匀速或者变速。
所述外壳1位于冷却空间103区域的表面上设置有散热鳍片7。在本实施例中，所述散热鳍片7为金属铜，因为金属铜为高热导性材料，可以选择其他导热性较好的金属替代，如银、金、铝和铁等，还可以采用陶瓷材料，比如氮化铝、碳化硅、氧化铝等。所述外壳1内部远离色轮3的一端设置有多个柱状散热鳍片7，当然也不限于柱状，满足散热鳍片7与外壳1有尽可能大的接触面积的任意形状均可。所述散热鳍片7可吸收气流回路中的热量，再通过外壳1的热传导，将热量释放到空 气中；所述柱状散热鳍片7可以设置在外壳内表面和/或外壳外表面，在本实施例中，所述柱状散热鳍片7设置在外壳外表面，在冷却空间103区域的表面上，还可以通过设置增加散热器、热管、水冷等散热装置，来加强冷却空间103(即冷风区)的降温效果。
所述色轮模组100还包括鼓风机8，所述鼓风机8设置于所述第一气流通道4或者第二气流通道5内，位于所述隔板2的一侧。在本实施例中，鼓风机8设置于隔板2的右侧对应的第二气流通道5内，除了鼓风机8进风口的方向不一致，鼓风机8设置于第一气流通道4内的原理与其一致。当驱动装置33高速旋转时，色轮3相当于一个离心风扇，气体从鼓风机8的进风口进入，在色轮3的作用下加压，即进风侧的气流贴合隔板2，直接吹向色轮3旋转的方向，气体沿着第二气流通道5到达安装空间101内与基板31和风扇叶片组32进行热交换，气体被加热，再在在色轮3的作用下加压，气体沿着第一气流通道4达到冷风区，通过外壳1和散热鳍片7的热传导作用将热量稀放到空气中，气体被冷却，整个过程形成较强的扰流。在一些实施例中，鼓风机8可以采用轴流风扇或离心风机等具有进出风作用的机器替代。
色轮模组100还包括透明盖板9，外壳1设置有开口，透明盖板9盖设于所述开口处，用于将所述开口封闭，波长转换层与透明盖板9相对应。在本实施例中，透明盖板9的高度为D1，与光波长转换层的直径一样，光波长转换层的直径与基板31相同，为了利于激光能够穿透壳体1入照射到波长转换层上，且波长转换层产生的受激光能够穿透壳体1出射，应当保持激发光源到基板31的光路是畅通的，至少在外壳1上设置一个通光孔用于入射激发光和/或出射受激发光，所以所述外壳1至少与色轮3相对应的区域采用的透明的材料，即D1大于光波长转换层的直径或宽度，在一些实施例中，所述外壳1可以是全透明材料制成。
请参见图2，与图1不同的是，基板31的数量为两片，分别为第一 基板311和第二基板312，所述第一基板311和第二基板312均与所述驱动装置33的转动轴331相固定，其中，所述第一基板311和第二基板312相对设置，并且所述第一基板311和第二基板312之间具有空腔。所述波长转换层设置于所述第一基板远离所述第二基板的一表面S3，风扇叶片组32固定于所述第二基板312面向所述第一基板的一表面S5。所述第一基板311和第二基板312均为圆形基板，在本实施例中，基板31为圆形铝合金盘，在一些实施例中，基板31的形状以及材料可以依据实际需求设置。
所述第一基板311上设置有通风孔6，所述通风孔6与空腔连通。在本实施例中，第一基板101上设置的通风孔6分别为关于转动轴331对称的第一通风孔和第二通风孔，且与第一基板311和第二基板312之间具有形成的圆柱体空腔相连。值得注意的是，通风孔的个数并不限制于实施例中所述的个数，且通风孔的形状可以是圆形孔或者方形孔等结构。
所述外壳1位于冷却空间103区域的表面上设置有散热鳍片7。在本实施例中，所述散热鳍片7为金属铜，因为金属铜为高热导性材料，还可以选择其他导热性较好的金属替代，比如银、金、铝和铁等，还可以采用陶瓷材料，比如氮化铝、碳化硅、氧化铝等。所述外壳1内部远离色轮3的一端设置有多个柱状散热鳍片7，当然也不限于柱状，满足散热鳍片7与外壳1有尽可能大的接触面积的任意形状均可。所述散热鳍片7可吸收气流回路中的热量，再通过外壳1的热传导，将热量释放到空气中；所述柱状散热鳍片7可以设置在外壳内表面和/或外壳外表面，在本实施例中，所述柱状散热鳍片7设置在外壳内表面，在冷却空间103区域的表面上，还可以通过设置增加散热器、热管、水冷等散热装置，来加强冷却空间103的降温效果。
本申请实施例提供的色轮模组通过提供一种色轮模组，包括：外壳， 设置有收容空间，所述收容空间划分有色轮安装空间、连接空间和冷却空间；隔板，设置于所述连接空间，并且将所述连接空间分割成第一气流通道和第二气流通道，其中，所述第一气流通道分别与色轮安装空间和冷却空间连通，所述第二气流通道分别与色轮安装空间和冷却空间连通，所述色轮安装空间、第一气流通道、冷却空间和第二气流通道闭合形成气流回路；色轮，安装于所述色轮安装空间。实现在外壳全封闭状态下，色轮与外部空气之间的热交换，有效提高了色轮的散热效果。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；在本申请的思路下，以上实施例或者不同实施例中的技术特征之间也可以进行组合，步骤可以以任意顺序实现，并存在如上所述的本申请的不同方面的许多其它变化，为了简明，它们没有在细节中提供；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
