具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对本申请进行详细描述。
请参阅图1-图2所示，本申请揭示了一种配光角度可控的混光灯具100，包括：壳体1、光源组件2、反光杯组件3以及固定件4。本申请的配光角度可控的混光灯具100，不仅能够实现混光均匀的光学效果，还能够对光源照射角度进行二次调整，以在满足灯具混光要求的同时满足配光要求。
如图2-图7所示，所述壳体1设有安装空间11以及贯通所述安装空间11的安装口12；所述光源组件2位于所述安装空间11内并固定在所述壳体1上；所述反光杯组件3位于所述安装空间11内并与所述光源组件2连接，所述反光杯组件3还与所述壳体1连接并外露于所述安装口12；所述固定件4环设在所述壳体1的内周壁上。
具体地，所述壳体1包括第一壳体13和第二壳体14，所述第二壳体14配置为与所述第一壳体13旋转连接。所述第一壳体13的朝向第二壳体14一侧设有挂板131，所述第二壳体14的内侧壁上对应设有限位部141，所述挂板131旋入所述限位部141，使所述第一壳体13与所述第二壳体14固定连接。在所述挂板131的末端还设有定位件132，以在所述挂板131旋入所述限位部141后限位所述挂板131和所述限位部141，防止所述配光角度可控的混光灯具100在使用过程中所述第二壳体14从所述第一壳体13一端脱落。
所述光源组件2固定在所述第一壳体13内，所述固定件4与所述第一壳体13螺纹连接。所述反光杯组件3包括第一反光杯31、第二反光杯32以及位于所述第一反光杯31和所述第二反光杯32之间的磨砂板33。所述磨砂板33的外周边缘与所述固定件4固定连接，具体地，所述磨砂板33卡设在所述固定件4内，以将所述磨砂板33固定安装在所述第一壳体13内，所述第一反光杯31的一端与所述光源组件2连接，另一端与所述磨砂板33连接，以在所述磨砂板33与所述第一反光杯31之间形成混光腔310，也就是说，所述混光腔310位于所述第一壳体13内。所述第一壳体13内还设有限位架5，所述限位架5设有限位口51，所述光源组件2收容在所述限位架5内部并部分曝露于所述限位口51，所述第一反光杯31插入所述限位口51内与所述光源组件2接触，所述限位架5不仅将所述光源组件2限位在所述第一壳体13上，也进一步限位所述第一反光杯31，防止所述第一反光杯31发生位置移动，而导致所述光源组件2射出的光线不能完全射入所述混光腔310内。
所述第二反光杯32与所述第二壳体14固定连接并外露于所述安装口12。具体地，所述第二反光杯32部分收容在所述第一壳体13内，所述安装口12开设在所述第二壳体14上，所述安装口12的内侧环设有支台(未标号)，所述第二反光杯32与所述第二壳体14磁吸连接并卡设在所述支台上，实现所述第二反光杯32与所述第二壳体14的固定连接。在其他实施例中，也可以在所述第二反光杯32的外周壁上设置挂钩，所述第二反光杯32与所述第二壳体14配置为旋转连接的方式，只要将所述第二反光杯32与所述第二壳体14固定连接即可，对此不作限制。
所述磨砂板33为透光板，所述光源组件2配置为发出多色光，该多色光在所述混光腔310内进行混光和初始配光后射入所述第二反光杯32进行二次配光角度调整。可以理解的是，所述第一反光杯31和所述磨砂板33都单独具有混光和配光的作用，使该多色光在所述混光腔310内混光更加均匀。所述第二反光杯32与所述磨砂板33间隔设置，当然，在另一实施例中，所述第二反光杯32与所述磨砂板33也能够呈接触式连接，只要满足能够对光线照射角度进行二次调整即可。所述第二反光杯32进行二次角度调整，这样也就实现了角度可控的混光效果。
结合图8-图13所示，在本申请中，所述磨砂板33可以由不同的pc材质注塑而成，而通过改变所述磨砂板33的注塑材质，能够实现不同角度配光且多色混光均匀的效果。以下将对磨砂板33的三种具体材质进行举例说明，但并不以此为限。
实施例一，当所述磨砂板33的注塑材质为透明pc时，此时整灯光束角大致在25度左右。
实施例二，当所述磨砂板33的注塑材质为扩散pc材料一时，此时整灯光束角大致在38度左右。
实施例三，当所述磨砂板33的注塑材质为扩散pc材料二时，此时整灯光束角大致在50度左右。
需要说明的是：扩散pc材料一和扩散pc材料二为在透明pc内增加具有扩散属性的面粒子混合得到，通过调整面粒子的浓度配比能够控制扩散pc材料的雾度。也就是说，扩散pc材料一和扩散pc材料二为一种透光而不透明的光扩散材料，其中，扩散pc材料一的型号可以选用拜耳021069，扩散pc材料二的型号可以选用帝人3107，此处不作限制。
在本实施例中，所述第一反光杯31和所述第二反光杯32均为上下通透的锥形杯。优选地，所述第二反光杯32任意平面的内径大于所述第一反光杯31任意平面的内径，所述第一反光杯31内径最大的一端朝向所述磨砂板33，所述第二反光杯32内径最小的一端朝向所述磨砂板33，从而自所述混光腔310内射出的光线能够全部射入所述第二反光杯32内进行二次角度调整。
综上所述，本申请通过将反光杯组件3设置在壳体1的安装空间11内并与光源组件2连接，并且反光杯组件3包括第一反光杯31、第二反光杯32以及位于所述第一反光杯31和所述第二反光杯32之间的磨砂板33；并通过将磨砂板33的外周边缘与固定件4固定连接，以将第一反光杯31的一端与光源组件2连接，另一端与磨砂板33连接，进而在磨砂板33与第一反光杯31之间形成混光腔310，同时将第二反光杯32与壳体1固定连接并外露于安装口12。相较于现有技术，本申请的配光角度可控的混光灯具100，不仅能够实现混光均匀的光学效果，还能够对光源照射进行二次角度调整，以在满足混光要求的同时达到配光要求。
以上实施例仅用以说明本申请的技术方案而非限制，尽管参照较佳实施例对本申请进行了详细说明，本领域的普通技术人员应当理解，可以对本申请的技术方案进行修改或者等同替换，而不脱离本申请技术方案的精神和范围。
