下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。
实施例一
本实施例提供了一种复眼透镜装置，如图2a所示，包括相互平行的第一镜片20和第二镜片21，第一镜片20的出光面202具有第一复眼透镜阵列，即第一镜片20的出光面202具有呈阵列式排布的多个第一复眼透镜2020，第二镜片21的入光面211具有第二复眼透镜阵列，即第二镜片21的入光面211具有呈阵列式排布的多个第二复眼透镜2110，第二镜片21的出光面212具有第三复眼透镜阵列，即第二镜片21的出光面212具有呈阵列式排布的多个第三复眼透镜2120。
如图2a所示，第一镜片20的入光面201为平面，第一镜片20的入光面201和出光面202为相对的两个表面，第二镜片21的入光面211和出光面212也为相对的两个表面，且第二镜片21的入光面211与第一镜片20的出光面202相对设置，基于此，本实施例中的第一复眼透镜阵列与第二复眼透镜阵列相对设置，且一一对应的第二复眼透镜2110与第一复眼透镜2020大小相等，第三复眼透镜2120小于第二复眼透镜2110。
如图2b所示，第一复眼透镜2020具有凸起的表面2021以及与该凸起表面2021相对的底面2022，第二复眼透镜2110具有凸起的表面2111以及与该凸起表面2111相对的底面2112，第三复眼透镜2120具有凸起的表面2121以及与该凸起表面2121相对的底面2122。
其中，第二复眼透镜2110的凸面2111与第一复眼透镜2020的凸面2021相对，第三复眼透镜2120的底面2122与第二复眼透镜2110的底面2112相对，并且，第二复眼透镜2110与第一复眼透镜2020大小相等是指第二复眼透镜2110的底面2112的直径与第一复眼透镜2020的底面2022的直径相等，且第二复眼透镜2110的凸面2111与第一复眼透镜2020的凸面2021具有相同的曲率。第三复眼透镜2120小于第二复眼透镜2110是指第三复眼透镜2120的底面2122的直径小于第二复眼透镜2110的底面2112的直径。
由于第一复眼透镜2020的焦点位于第二复眼透镜2110的中心上，因此，入射光束经过第一复眼透镜2020后聚焦到第二复眼透镜2110的中心上，由于第一复眼透镜2020将入射的宽光束分成了多个细小的光束，而分成的每个细小光束又与对称的细小光束进行了叠加，因此，每个细小光束范围内的微小不均匀性都得到了补偿，从而使得整个光束内的光能量得到了有效且均匀的利用。
此后，经过第二复眼透镜2110的光线入射到第三复眼透镜2120上，由于第三复眼透镜2120小于第二复眼透镜2110，因此，可以通过第三复眼透镜2120增加光线的出光角度，在提高出射光线的均匀性的基础上，进一步提高复眼透镜装置的出光效率。本实施例中，第三复眼透镜2120的表面可以为光滑的表面，也可以为磨砂的表面，以通过磨砂的表面进一步提高出射光线的均匀性。
本实施例提供的复眼透镜装置，由于第一镜片的出光面上的第一复眼透镜与第二镜片的入光面上的第二复眼透镜大小相等，且所述第一复眼透镜的焦点位于所述第二复眼透镜的中心上，因此，可以将光线均匀化，并且，由于第二镜片的出光面具有第三复眼透镜阵列，第三复眼透镜小于第二复眼透镜，因此，可以增大光线的出光角度，在提高出射光线的均匀性的基础上，提高复眼透镜装置的出光效率。
实施例二
本实施例提供了一种光源系统，如图3所示，包括具有至少一个发光模组301的发光部件302、对发光部件302出射的光线进行收光的第三透镜303、将第三透镜303出射的光线调整成具有一定角度的光的第一透镜304、位于第一透镜304出射光的光路上的复眼透镜装置305和将复眼透镜装置305出射的光投影至预定平面的第二透镜306。
本实施例中，复眼透镜装置305为上述实施例一提供的复眼透镜装置，即复眼透镜装置305包括相互平行的第一镜片和第二镜片，且第一镜片的出光面具有第一复眼透镜阵列，第二镜片的入光面具有第二复眼透镜阵列，第二镜片的出光面具有第三复眼透镜阵列，且第一镜片的出光面与第二镜片的入光面相对设置，第二复眼透镜与第一复眼透镜大小相等，第三复眼透镜小于第二复眼透镜，以在提高出射光线均匀性的基础上，提高复眼透镜装置305的出光效率。
如图3所示，发光部件302上的发光模组301发射光线后，第三透镜303对光线进行收光，第一透镜304将第三透镜303出射的光线调整成具有一定角度的光，该第一透镜304出射的光以一定的角度入射到复眼透镜装置305上，复眼透镜装置305对近似平行的入射光进行匀光后，第二透镜306将其投影至预定的平面上，其中，第二透镜306可相对复眼透镜装置305移动，以调节输出光斑的大小。由于复眼透镜装置305中的第三复眼透镜2120可以改变光线的出射角度，因此，可以在提高出射光线均匀性的基础上，提高出光效率。
本实施例中，发光模组301包括衬底3010和位于衬底3010表面的LED光源3011，如图4所示，位于衬底3010表面的LED光源3011可以包括四个白色LED光源W、两个红色LED光源R、两个蓝色LED光源B、两个绿色LED光源G和两个琥珀色LED光源A，并且这些LED光源呈正六边形阵列排布，以形成均匀的光斑。本实施例提供的光源系统，通过采用上述LED光源使得混合后的白光更加均匀，并且，通过采用琥珀色LED光源，使得混合后的白光的颜色更加纯正，更加符合照明系统的需求。
本实施例中，发光部件302可以包括一个发光模组301，也可以包括多个发光模组301，以增大光源系统的出光亮度。当发光部件302包括多个发光模组301时，优选的，多个发光模组301呈圆形阵列排布，其中，至少一个发光模组位于该圆形阵列的圆心上，其他发光模组均匀排布于该圆形阵列的圆环上。
如图5所示，发光模组3010位于圆形阵列的圆心上，发光模组3011~发光模组3016依次排布于圆形阵列的圆环上，并且，发光模组3011~发光模组3016的各个边相互平行，当然，本实用新型并不对此进行限定，如图6所示，发光模组3011~发光模组3016距离圆心最近的边可以位于圆环的各个切线上。
本实施例中，位于圆环上的发光模组均匀排布，如图5和6所示，发光模组3011、发光模组3010和发光模组3014位于同一条直线上，发光模组3012、发光模组3010和发光模组3015位于同一条直线上，发光模组3013、发光模组3010和发光模组3016位于同一条直线上，并且，各个直线之间的夹角大小相等，例如图5中的夹角a等于夹角b。
此外，本实施例中每个发光模组上的LED光源均呈近似正六边形阵列排布。如图7所示，该近似正六边形阵列包括第一光源阵列80和位于第一光源阵列四周的第二光源阵列81，其中，第一光源阵列80为矩形阵列，第二光源阵列81包括第一光源组810、第二光源组811、第三光源组812和第四光源组813，且第一光源组810~第四光源组813依次排布于第一光源阵列80的四个边上。
本实施例中，如图7所示，第一光源阵列80包括四个白色的LED光源W，第二光源阵列81中的第一光源组810包括沿顺时针方向依次排列的一个红色LED光源R和一个琥珀色LED光源A、第二光源组811包括沿顺时针方向依次排列的一个蓝色LED光源B和一个青色LED光源C，第三光源组812包括沿顺时针方向依次排列的一个红色LED光源R和一个琥珀色LED光源A，第四光源组813包括沿顺时针方向依次排列的一个深蓝色LED光源dB和一个绿色LED光源G。
在其他实施例中，发光模组的另一种LED光源排列结构如图8所示，第一光源阵列80包括四个白色的LED光源W，第二光源阵列81中的第一光源组810包括沿顺时针方向依次排列的一个红色LED光源R和一个琥珀色LED光源A、第二光源组811包括沿顺时针方向依次排列的一个蓝色LED光源B和一个绿色LED光源G，第三光源组812包括沿顺时针方向依次排列的一个红色LED光源R和一个琥珀色LED光源A，第四光源组813包括沿顺时针方向依次排列的一个蓝色LED光源B和一个绿色LED光源G。
在另一个实施例中，发光模组的又一种LED光源排列结构如图9所示，第一光源阵列80包括四个白色的LED光源W，第二光源阵列81中的第一光源组810包括沿顺时针方向依次排列的一个红色LED光源R和一个白色LED光源W、第二光源组811包括沿顺时针方向依次排列的一个蓝色LED光源B和一个绿色LED光源G，第三光源组812包括沿顺时针方向依次排列的一个红色LED光源R和一个白色LED光源A，第四光源组813包括沿顺时针方向依次排列的一个蓝色LED光源B和一个绿色LED光源G。
由于彩色LED光源位于白色LED光源的四周，因此，可以使得混合后的白光的颜色更加均匀，并且，通过琥珀色LED光源、青色LED光源或深蓝色LED光源的采用，可以扩大发光部件302发射光的色域，使得混合后的白光的颜色更加纯正。
本实施例中的发光部件302可以包括如图7所示的多个发光模组，也可以包括如图8所示的多个发光模组或如图9所示的多个发光模组，还可以包括如图7~9中所示的至少两种发光模组，本实用新型并不对此进行限定。
本实施例提供的光源系统，通过复眼透镜装置提高了出射光线的均匀性以及出光效率，通过圆形矩阵排列的发光模组提高了出光亮度，通过近似正六边形矩阵排列的LED光源提高了混合后白光的均匀性，并通过琥珀色LED光源的采用，使得混合后的白光颜色更加纯正，更符合光源照明系统的需求。
