具体实施方式
下面结合附图并通过实施方式来说明本公开的技术方案。
如图1a所示，本公开提供的一种具有大光斑效果的工矿灯，包括反射器1、LED光源2和灯外壳3，其中：
LED光源2安装于反射器1的凹陷部(对于碗型结构为反射器1内壁的底部，对于球面结构为反射器1内壁的底部或顶部，顶部或底部仅仅由于视角决定的)，灯外壳3包括第一灯外壳31和第二灯外壳32，反射器1可拆卸地安装在第一灯外壳31的内部，第一灯外壳31安装在第二灯外壳32上。
在一实施例中，本公开还提供一种灯具，包括反射器1，反射器1可以为球面或碗型结构，在一实施例中，反射器1为球面结构。反射器1的内壁设有蜂窝状或鳞形的反射层，所述反射层包括多行呈蜂窝状或鳞形的排列的反射面，且上述所有反射面均为面反射。在一实施例中，可以对所有反射面均作镜面处理(即所有反射面为镜面反射)。在一实施例中，每层所述反射层的反射面的数量相同，每层所述反射层的反射面的数量也可以不相同，根据实际应用情况来确定每层反射层的反射面数量是否相同。本公开实施例提供的工矿灯能够实现照射面积大、发光均匀的效果。
在一实施例中，本公开通过设置蜂窝状或鳞形的反射层中每行反射面的数量相同的方式，使得LED光源2发出的光线经过反射器1内壁上的蜂窝状反射面反射后的光束角度均相同，增大了照射范围，并产生比较柔和的大光斑效果，进而使得人们在这种光线下工作具有舒适的感觉。通过将反射面均作镜面处理， 使得LED光源2照射到经过被处理面的光线作有方向性的镜面反射，而不是漫反射，从而达到混光均匀，并且具有光能量损耗小，反光光效高，反光光线方向可控和光源利用率高的优点。
在一实施例中，每层反射层中的所有反射面到LED光源2的距离均相同，在一实施例中，每一层的蜂窝形状反射面是根据抛物线把蜂窝形状反射面放大一定的倍率后置于相应的位置上，因此可以保证每层蜂窝状反射面的数量相同。
在一实施例中，所述灯具的同一反射层的的所有反射面到所述LED光源2的距离不都相同。
在一实施例中，上述反射面的形状为多边形，例如六边形、八边形或菱形。在一实施例中，只要满足反射层的每一层反射面的数量相同的反射面的形状均可以作为本公开的反射面形状。在一实施例中，蜂窝状排列的反射面的形状为六边形。
在一实施例中，如图1b所示，图1b是本公开实施例提供的灯具的部分结构示意图，以反射面的形状为六边形为例，一行反射面可以理解为一个纬线方向上排列的多个反射面(不限于图中的三个)，图1b中以第一纬线方向、第二纬线方向以及第三纬线方向的部分反射面为例，分别表示第一行反射面、第二行反射面以及第三行反射面，上述三行反射面但不限于这三行反射面构成了多行呈蜂窝状排列的反射面，可以理解为在多个纬线方向上分别排列反射面，每层反射层包括多个反射面，多行反射面整体上构成蜂窝状。

如图3所示，为使第一灯外壳31与第二灯外壳32更好地连接，在凸起311和凹槽321之间充满胶水322，这样可以更加紧密地固定第一灯外壳31和第二灯外壳32。
在一实施例中，第一灯外壳31和第二灯外壳32可以通过螺丝或卡扣固定。
请继续参阅图2，第一灯外壳31内设置有至少一个安装孔(图中未示出)，反射器1的第一端设置有至少一个第一定位孔11，至少一个安装孔与至少一个第一定位孔11通过连接件固定。在一实施例中，该连接件可以为螺栓也可以为固定柱。
在一实施例中，安装孔的数量与第一定位孔11的数量相同。
在一实施例中，第二灯外壳32内设有电路板21，电路板21上设置有至少一个第二定位孔22，反射器1的第二端设置有至少一个定位柱12，至少一个定位柱12固定于至少一个第二定位孔22内。通过将反射器1的上下两端分别固定在第一灯外壳31和第二灯外壳32上，可以确保反射器1更加稳定。
在一实施例中，定位柱12的数量与第二定位孔22的数量相同。
在一实施例中，反射器1的第一端可以理解为远离反射器1凹陷部的一端，反射器1的第二端可以理解为靠近反射器1凹陷部的一端。
在一实施例中，反射器1的第一端设置有至少一个第一定位孔11，电路板21上不设置第二定位孔22，即，仅通过第一定位孔11实现固定反射器1的位置。
在一实施例中，电路板21上设置有至少一个第二定位孔22，反射器1的第一端不设置第一定位孔11，即，仅通过第二定位孔22实现固定反射器1的位置。
