为了方便LED灯板、反光罩和散热体三者相互之间的固定，本发明所提供发光角度广的LED灯中反光罩的窄口外口沿上设有与相配合LED灯板形似的座板，并且在该座板上分布有与相配合LED灯板上的多个LED发光源对称的发光孔以及固定机构。
上述所述的曲面可以是符合曲面公式：Z=0.34(X2+Y2)-3   其中：0≤Z≤5。符合该曲面公式所形成的反光罩，当LED发光光源的光照射在反光罩上后，能使光线经折光后从灯罩的各方向射出，以保证了最大范围的光照角度。

 本发明的最佳实施方式
如图1和图2所示，本实施例提供一种广角度发光LED球泡灯，包括灯头1、由塑胶底座2-1、电源组件2-2、散热体2-3和灯罩2-4组成的灯体2以及固定在灯体2上的LED灯板3，其中该塑胶底座2-1的一端与灯头1旋接，其另一端***散热体2-3上的型腔内形成容置腔，电源组件2-2至于该容置腔内，灯罩2-4旋接在散热体的型腔外端面5周圈的侧壁6上，LED灯板3固定在散热体的型腔外端面5上，在LED灯板3上盖接有反光罩4，如图3所示，该反光罩4的外表面为将LED灯板3发出的部分光源反射向灯头1周圈方位的曲面4-1，同时反光罩4和LED灯板3均位于灯罩2-4内，上述所述的曲面4-1是符合曲面公式：Z=0.34(X2+Y2)-3   其中：0≤Z≤5。符合该曲面公式所形成的反光罩，当LED发光光源的光照射在反光罩上后，能使光线经折光后从灯罩的各方向射出，以保证了最大范围的光照角度。
本实施例在具体使用中：反光罩4上的曲面4-1对LED灯板3发出的部分光源进行聚光处理后形成强光，上述强光就有力射出灯罩2-4，此时由于该曲面4-1的曲率是经过精密的光学计算得出来，其能保证此强光的射出方向正好是灯头1方向，而LED灯具在日常使用中其灯头1方位也是最难处理的光照死区，所以用强光来照亮灯头1方位的暗区，这样的方式增大了传统LED灯的发光角度。
 本发明的实施方式
如图4和图5所示，本实施例提供的广角度发光LED球泡灯，其大体结构与实施例1一致，但是为了方便LED灯板3、反光罩4和散热体2-3三者相互之间的固定，本实施例所提供广角度发光LED球泡灯中反光罩4的窄口外口沿上设有与相配合LED灯板3形似的座板7，并且在该座板7上分布有与相配合LED灯板3上的多个LED发光源3-1对称的发光孔7-1以及预设螺栓孔。
本实施例所提供广角度发光LED球泡灯中LED灯板3、反光罩4和散热体2-3三者相互之间的安装方式如下：首先将LED灯板3安装到散热体的型腔外端面5上，接着将带有座板7的反光罩4安装到LED灯板3上，并且要确保LED灯板3上的所有LED发光源3-1都要对应的贯穿座板7上的发光孔7-1，最后将上述三者通过螺栓紧固即可。
