现有结构存在以下缺陷：
一、铝基板一般采用如图1和图2所示的四边相交结构或两边相交结构，其中弧线段a是与散热件接触的有用散热部位，直线段b是不与散热件接触的浪费掉的散热位置，因为存在直线段b，使得铝基板与散热件的接触面积小，不利于热量传递；
二、铝基板安装LED芯片后存在很大的空闲区域，造成材料浪费，增加LED灯的成本；
三、LED芯片发出的光线经玻壳内壁反射后，得不到再利用，光通量和反光效率。

所述球泡通过扣位和胶连接固定罩在灯体上，球泡和灯体之间的扣位是：球泡的下端形成卡扣，灯体的上端形成卡位槽，通过卡扣卡入卡位槽中，使球泡连接在灯体上，在扣位处加胶，使球泡固定在灯体上。
所述圆环状铝基板的内圈为完整的圆形。
所述圆环状铝基板的内圈形成两个凸耳，凸耳上开设通孔，贴片母端连接器对应通孔的位置安装在凸耳上，中板的边缘形成台阶与铝基板的内圈配合，中板上形成容纳凸耳的沉槽，沉槽上形成带插孔的导柱，中板由下向上嵌置在铝基板的内圈中，导柱的上端插入通孔中，中板的下方形成挂钩，电路板借助挂钩固定安装在中板的下方，电路板上安装了插针公端，插针公端穿过插孔与贴片母端连接器电连接。
所述插孔的下端形成喇叭状导入角。
所述球泡和灯体的整体形状为A型、G型、R型或B型。
