具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明具体实施例及相应的附图对本发明技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
以下结合附图，详细说明本发明各实施例提供的技术方案。
请参考图1-4，本发明实施例公开一种光源模组，所公开的光源模组包括基座100和安装在基座100上且呈阵列分布的至少两个发光体200。
本发明所公开的光源模组还包括至少两个透镜模组300，至少两个透镜模组300均固定在基座100上，至少两个透镜模组300呈阵列分布。每个透镜模组300均包括至少一个透镜单元310，每个透镜单元310罩在相对应的发光体200上。通常情况，透镜模组300为一体式结构，此种情况下，透镜模组300包括多个透镜单元310时，多个透镜单元310可以一体成型。
通常情况下，每个透镜单元310均有相对应的一个或至少两个发光体200与之配合，发光体200发出的光线经过透镜单元310以实现为照明灯具配光。在实际的设计过程中，可以根据发光体200的排布方式及光源模组的尺寸规格来定义透镜模组300的尺寸，进而通过阵列分布的至少两个透镜模组300实现对至少两个发光体200的分别罩设，进而实现为其配光。
本发明实施例公开的光源模组包括至少两个透镜模组300，至少两个透镜模组300阵列分布在光源模组的基座100上，每个透镜模组300包括至少一个透镜单元310，每个透镜单元310罩在相对应的发光体200上，进而实现配光。呈阵列分布的透镜模组300相当于将现有技术中罩设在所有发光体上的一个整体透镜实施分割，进而得到较小尺寸的透镜模组300，然后通过每个透镜模组300的透镜单元310为发光体200配光，这就使得透镜能够较为灵活地与相对的发光体200进行匹配，最终达到较好地适应照明灯具形状的目的，方便了照明灯具的装配。
上述结构的照明灯具有利于照明灯具的标准化，不同的照明灯具可以通过不同数量的小尺寸透镜模组300拼接后进行装配，这能够降低透镜模组300的成型难度，提升产品的精度，有利平台化设计，当然也能减小相同配光时透镜的重复开模，减小照明灯具的生产成本。
为了便于透镜模组300与基座100的组装，优选的方案中，每个透镜模组300与基座100中，一者上设置有定位凸起，另一者上设置有定位凹陷，定位凸起与定位凹陷定位配合。在实际的组装过程中，操作人员可以先通过定位凸起与定位凹陷将透镜模组300定位在基座100上，然后再进行后续的连接。上述结构能方便操作人员的组装，进而能提高组装效率。请参考图3，一种具体的实施方式中，透镜模组300具有定位凸起320，基座100具有定位凹陷110，定位凹陷110可以为定位凹槽或定位孔。
在实际的组装过程中，操作人员需要向基座100上组装透镜模组300，为了避免装反，优选的方案中，透镜模组300和基座100中，一者具有防呆凸起，另一者具有防呆凹陷。防呆凸起与防呆凹陷定位配合，进而起到防呆的作用，避免装配失效。
通常情况下，透镜模组300通过固定连接件固定在基座100上，例如螺纹连接件、锚固件、卡扣等。一种具体的实施方式中，固定连接件为塑料铆钉400，如图1-4所示。具体的，塑料铆钉400的一端包括多条弹性涨紧条，塑料铆钉400的一端穿过基座100上的连接孔，多条弹性涨紧条 穿过连接孔后能够张开，进而保持透镜模组300与基座100之间的装配力。
本发明实施例中，透镜模组300包括至少一个透镜单元310，通常，每个透镜模组300包括多个透镜单元310，透镜单元310的结构有多种，请再次参考图1-4，一种具体的实施方式中，透镜单元310包括主体部311和配光部312。主体部311用于实现透镜单元310的组装，主体部311与基座100相连，且具有朝向基座100的连接面，配光部312是透镜单元310的光学部分，配光部312内凹于连接面，配光部312与基座100形成用于容纳发光体200的容纳腔。如图1-4所示，每个透镜模组300为一体式结构，此种情况下，每个透镜模组300所包含的多个透镜单元310集成为一体结构，相应地，主体部311也为一体式结构。
优选的方案中，主体部311可以为板状连接件，板状连接件使得主体部311的连接面为平面，进而能使得主体部311的连接面与基座100的安装面相贴合，能够实现透镜单元310更为稳定地安装。实现透镜模组300固定的固定连接件可以将主体部311固定在基座100上。
上述具体结构中，每个透镜模组300可以具有至少两个配光部312，至少两个配光部312一一对应地罩在发光体200上，即一个配光部312罩在一个发光体200上。当然，每个配光部312可以罩设在至少两个发光体200上，进而实现每个配光部312可以为至少两个发光体200同时实施配光。配光部312的数量与发光体200的阵列分布及透镜模组300的尺寸规格有关。如图1-2所示，图1和2所示的光源模组中，每个透镜模组300均包括4个透镜单元310，每个透镜单元310均具有一个配光部312，即每个透镜模组300包括4个配光部312。
本发明实施例公开的光源模组中，每个透镜模组300的配光方式可以相同，也可以不同。同理，同一个透镜模组300中，每个透镜单元310的配光方式相同，也可以不同。
在条件允许的前提下可以调整每个透镜模组300的透镜单元310的数量。请参考图5，图5为本发明实施例公开的第二种光源模组的结构示意图，图5所示的光源模组中，每个透镜模组500均具有4个透镜单元510，每个透镜单元510均包括主体部511和一个配光部512。4个透镜单元510可以为一体式结构。
透镜单元510的配光部512可以为长形结构。请参考图6和图7，图6和图7分别为沿配光部512的长度方向和宽度方向的局部剖视图。配光 部512在其长度方向为对称结构，如图6所示，配光部512在长度方向对光线的配光为对称配光。在宽度方向上，配光部512一侧的厚度大于另一侧的厚度，以驱使发光体投射的光线向着配光部512厚度较大的一侧偏折，如图7所示，进而形成非对称配光。
配光部512的内侧表面为入光面512a，配光部512的外侧表面为出光面512b，入光面512a和出光面512b均为曲面。一种具体的实施方式中，入光面512a和出光面512b均可以由多段弧形面平滑衔接而成。
请参考图8，图8为本发明实施例公开的第三种光源模组的结构示意图。图8所示的光源模组中，每个透镜模组600具有12个的透镜单元610，每个透镜单元610均包括主体部611和一个配光部612。12个透镜单元610可以为一体式结构。图8所示的透镜模组600和图5所示的透镜模组500的区别在于所包含的透镜单元的数量不同，图8中的配光部612与图5中的配光部512的配光结构相同，故在此则不再赘述。
请参考图9，图9为本发明实施例公开的第四种光源模组的结构示意图，图9所示的光源模组中，透镜模组700可以具有6个透镜单元710。每个透镜单元710均包括主体部711和配光部712，6个透镜单元710可以为一体式结构。
透镜单元710的配光部712也可以为长形结构。请参考图10-11，图10和图11分别为沿配光部712的长度方向和宽度方向的局部剖视图。配光部712在其长度方向为对称结构，如图10所示，配光部712在长度方向对光线的配光为对称配光。在宽度方向上，配光部712一侧的厚度大于另一侧的厚度，以驱使发光体投射的光线向着配光部712厚度较大的一侧偏折，如图11所示，进而形成非对称配光。
配光部712的内侧表面为入光面712a，配光部712的外侧表面为出光面712b，入光面712a包括在配光部712的宽度方向上相连的弧形面712a1和平面712a2，出光面712b由多段弧形面平滑衔接而成，配光部712上与弧形面712a1所对应的一侧厚度大于另一侧的厚度。
本发明实施例中，基座100可以为PCB板，PCB板的端部可以设置有电连接器120，电连接器120通过与电源的连接，实现为发光体200供电。优选的方案中，发光体200为LED灯珠，LED灯珠具有产热少、节能、环保、使用寿命长等优点。
本发明中，基座100通常根据照明灯具的结构来确定。图1、图2、 图5、图8和图9所示的光源模组中，基座100为方形板。相应地，发光体和透镜模组可以呈方形阵列布置在基座100上，且相邻的两个透镜模组相对的边缘相贴合。请参考图12-14，基座100还可以为圆形板，至少两个透镜模组可以围绕基座100的中心彼此间隔，且均匀分布，图12-14中的透镜模组与图5中的透镜模组结构相同，在此则不再赘述。本发明不限制基座100的具体形状。
基于本发明实施例公开的光源模组，本发明实施例还公开一种照明灯具，请参考图15和图16，所公开的照明灯具包括灯头10和灯架20，灯头10包括光源模组101，灯架20与灯头10支撑相连。其中，光源模组101为上文实施例所述的光源模组。
灯架20是灯头10的支撑部件，通常为杆件。本发明实施例公开的照明灯具还包括底座30，底座30设置在灯架20的底端，进而能提高照明灯具的稳定性。
光源模组101还包括驱动器，驱动器安装在基座100上，且与发光体200电连接。具体的，驱动器可以与基座100为一体式结构，当然，驱动器也可以通过连接件或连接结构与基座100固定相连。
请再次参考图16，一种具体的实施方式中，灯头10可以包括光源模组101、反射罩102、散热壳体103和玻璃面罩104，散热壳体103设置有安装凹陷1031，玻璃面罩104与散热壳体103相连，玻璃面罩104与安装凹陷1031形成容纳空间，光源模组101和反射罩102均设置在容纳空间内，且与散热壳体103相连；光源模组101的发光区域位于反射罩102所围成的区域内，反射罩102能够为光源模组101所投射的光线实施配光。散热壳体103可以采用散热性能良好的金属壳体。
为了提高容纳空间的密封性，玻璃面罩104与散热壳体103之间还设置有密封圈105。具体的，玻璃面罩104可以通过螺钉106固定在散热壳体103上。
请再次参考图16，散热壳体103上还可以设置有电器腔107，电器腔107能够为灯头10的其它组成部件提供安装空间。散热壳体103可以设置有安装套108，安装套108能够与灯架20固定相连，进而能完成灯头10的安装。具体的，安装套108位于散热壳体103的一端，电器腔107位于安装凹陷1031与安装套108之间。
本发明实施例所公开的照明灯具可以是路灯、台灯、厂房吊灯等，本 发明实施例不限制照明灯具的具体种类。
本发明上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本发明的实施例而已，并不用于限制本发明。对于本领域技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
