在本发明中，LED芯片7与一体或者不一体的配件(连接丝)、芯柱2、金属丝结合后，再与驱动器4连接。
在本发明中，真空密封腔体内充所充的氦气、氩气或者氦氩混合气的压力为1个大气压左右，大气压过小，会对灯泡的寿命产生很大的影响，本发明经过反复实验，确定了在1个大气压左右，灯泡的使用寿命是最长的。
由图2和图3可知，在本发明中，每一根LED发光条3中的LED芯片7的连接，至少有一并联，LED发光条3之间的连接以串并联方式连接，并且LED发光条3可以在经过电源输出后在AC或DC电压下工作。这样的设计结构，使得LED发光条3可以在不同的电压下进行工作，无疑增加了其通用性。

在本发明中，LED灯泡壳1为普通石英玻璃，形状有ST64、ST58、ST48、ST45、PS60、PS55、G45、G60、G80、G95、G100、G120、G125、G200、G250、G300、C35、C45、T30、T32、T85、T25、T20、T38、T45、ST20、ST26、ED54、ED76、BT80、R39、R50、R63、R80、R95、R125、R160。

由图7可知，本发明还包括将电极引出装置固定在半透明陶瓷基板6上的固定装置10，该固定装置10为U型的铁镀镍或者铁镀银材料，通过铆压的机械方式和半透明陶瓷基板6进行连接。
在本发明中，LED发光条3主要是使用了倒装工艺来焊接LED芯片7。
在本发明中，LED芯片7为380-400NM的紫光和400-460NM的蓝光，蓝光芯片发射的蓝光激发红、绿荧光粉发射出红、绿光，混合透射出来的蓝光形成高显色指数的白光。
由图8可知，在本发明中，LED芯片7主要是用红、绿荧光粉11将LED芯片7包裹起来，均匀涂在LED芯片7的正反面，或者是：LED芯片7是将红、绿荧光粉11与硅树脂或者硅橡胶结合，同时360°包裹在LED发光条3上。
在本发明中，LED芯片7主要是采用了2-4V的LED低压芯片，选用该芯片可进一步延长芯片的使用寿命。
本发明主要是采用LED倒装芯片，所谓倒装芯片，就是直接将LED芯片7焊接在印有电路的半透明陶瓷基板6上，大大减少了工艺步骤和节约了金线成本，而且更容易实现机械化大批量生产。
本发明所使用的电源是超小体积的恒流电源，不仅能完美的控制电流，而且能组装在各种大小体积的电源容器内，给灯泡的种类、型号、外观、形状等带来无限的可能！
总的来说，本发明所用LED灯泡，发光条的连接方式呈多样化，灯泡壳和灯头的型号多样，大大增加了产品的通用性，并同时大大减小了成本。
