具体地，下面结合附图，对本申请实施例作进一步阐述。
实施例一
本申请实施例提供了一种复眼镜片模组，请参见图2(a)和图2(b)，其示出了本申请实施例提供的一种复眼镜片模组100在两个视角上的结构，所述复眼镜片模组100包括：第一塑料复眼镜片110、第二塑料复眼镜片120和长方体玻璃结构130。
所述第一塑料复眼镜片110，其在表面上设置有第一圆形区域111，所述第一圆形区域111设置为具有凹凸结构的复眼结构，所述第一圆形区域111配置为用于接收点光源所出射的圆形光源光斑；
第二塑料复眼镜片120，其在表面上设置有第二圆形区域121，所述第二圆形区域121设置为具有凹凸结构的复眼结构，所述第二圆形区域121配置为用于出射均匀化的圆形光斑；
其中，所述复眼结构由不定数量的小透镜平铺排列组成，如图2(a)和图2(b)所示，所述复眼结构由凹凸的多个小透镜周期性排列组成，在其他的一些实施例中，所述复眼结构可根据实际需要进行设置，不需要拘泥于本申请实施例的限定。
所述第一塑料复眼镜片110和所述第二塑料复眼镜片120通过粘合胶剂固定在所述长方体玻璃结构130的两侧，且有，所述第二塑料复眼 镜片120与所述第一塑料复眼镜片110中心对称设置，以使所述点光源出射的光斑能够通过所述第一塑料复眼镜片110入射到所述复眼镜片模组中，并通过所述第二塑料复眼镜片120出射。
在本申请实施例中，由于玻璃材质的热导率较塑料材质的热导率要高，材质可靠性高；塑料材质较玻璃材质结构的复眼凹凸特征结构的成型工艺要简单，塑料材质可靠性较玻璃材质稍差。利用这两种材质各自的优缺点，本申请实施例将复眼结构拆分为中心采用玻璃材质结构制成的长方体玻璃结构130，和两侧采用塑料材质通过注塑等方式成型的复杂的复眼凹凸镜片特征光学结构，也即是所述第一塑料复眼镜片110和所述第二塑料复眼镜片120，从而制成所述复眼镜片模组100。所述复眼镜片模组100在运行过程中所产生的热量通过薄且面积大的所述第一塑料复眼镜片110和所述第二塑料复眼镜片120快速传导到所述长方体玻璃结构130上，然后通过玻璃材质的所述长方体玻璃结构130快速传导至低温区，减少复眼镜片模组高温区域热集中，降低复眼镜片模组100的整体温升。需要注意的是，所述第一塑料复眼镜片110和所述第二塑料复眼镜片120在工艺成型过程中要求尽量要薄，且所述第一塑料复眼镜片110两侧四周的塑料结构113和所述第二塑料复眼镜片120两侧四周的塑料结构123的尺寸也需要越小越好，以减小所述复眼镜片模组100的整体热阻，加快散热。
在一些实施例中，请继续参见图2(a)和图2(b)，所述长方体玻璃结构130未设置有所述第一塑料复眼镜片110和所述第二塑料复眼镜片120的其他四个侧面133上设置有塑料壳体140。所述塑料壳体140可以是一体注塑直接在所述长方体玻璃结构130的四个侧面133形成的，也可以是在单独生产出来之后，通过卡扣固定、螺纹固定、榫卯结构固定、粘合固定等方式固定到所述长方体玻璃结构130上，具体地， 可根据实际需要进行设置，不需要拘泥于本申请实施例的限定。
在一些实施例中，所述粘合胶剂为胶水，所述第一塑料复眼镜片110和所述第二塑料复眼镜片120通过所述胶水固定在所述长方体玻璃结构130的两侧。需要注意的是，在粘合的过程中，需要保持所述第一塑料复眼镜片110上的复眼结构与所述第二塑料复眼镜片120上的复眼结构保持对齐，以使光线能够正常透射出射。
在一些实施例中，请参见图3(a)和图3(b)，其示出了本申请实施例提供的长方体玻璃结构在两个视角上的结构，所述长方体玻璃结构130用于固定所述第一塑料复眼镜片110的第一侧131，与所述长方体玻璃结构130用于固定所述第二塑料复眼镜片120的第二侧132平行设置。具体地，所述长方体玻璃结构130的第一侧131和第二侧132需要保持高精度的平面度及平行度，以尽量减少对光路出光方向的影响，使得出光能够保持平行出射。
在一些实施例中，请参见图4(a)和图4(b)，其示出了本申请实施例提供的第一塑料复眼镜片和第二塑料复眼镜片在两个视角上的结构，所述第一塑料复眼镜片110和所述第二塑料复眼镜片120平行设置。具体地，所述第一塑料复眼镜片110的基准面111和所述第二塑料复眼镜片120的基准面121都需要保持高精准的平面度，且在粘合的过程中，还需要保持所述第一塑料复眼镜片110的基准面111在所述长方体玻璃结构130的第一侧131的尺寸中心，所述第二塑料复眼镜片120的基准面121在所述长方体玻璃结构130的第二侧132的尺寸中心。此外，所述第一塑料复眼镜片110的侧边四面112需要保持垂直度，所述第二塑料复眼镜片120的侧边四面122也需要保持垂直度。
在一些实施例中，所述第一塑料复眼镜片110的表面积111与所述长方体玻璃结构130的第一侧131的表面积相同，所述第二塑料复眼镜 片120的表面积121与所述长方体玻璃结构130的第二侧132的表面积相同。
在一些实施例中，所述第一塑料复眼镜片110和所述第二塑料复眼镜片120的结构完全相同。所述第一塑料复眼镜片110和所述第二塑料复眼镜片120结构完全相同，则只需要一个模具即可生产所述第一塑料复眼镜片110和所述第二塑料复眼镜片120，且在使用时所述第一塑料复眼镜片110和所述第二塑料复眼镜片120皆可作为入光侧或出光侧，安装所述复眼镜片模组100时可以不用考虑所述第一塑料复眼镜片110和所述第二塑料复眼镜片120的安装方向是否正确的问题。
在一些实施例中，所述第二塑料复眼镜片120上复眼结构的面积大于所述第一塑料复眼镜片110上复眼结构的面积。所述第一塑料复眼镜片110和所述第二塑料复眼镜片120结构不同时，虽然需要两个模具分别生产所述第一塑料复眼镜片110和所述第二塑料复眼镜片120，但由于本身复眼结构的生产成本较高，在入光侧，也即是所述第一塑料复眼镜片110上，缩小复眼结构的面积，而由于入射到所述复眼镜片模组100的光斑小于从所述复眼镜片模组100出射的光斑，因此缩小所述第一塑料复眼镜片110的复眼结构的面积后，一方面能够保证所述复眼镜片模组100能够正常工作，另一方面也能够降低生产成本。
