本发明涉及 LED 照明领域，特别是一种灯头电连接结构。
近年来，LED 芯片作为光源运用于室内照明领域得到快速的发展。人们在不断探索一种制作工艺简便且性能稳定的 LED 灯。传统的 LED 球灯泡结构主要包括灯头、驱动、散热器、LED 铝基板和灯泡壳五个部分，LED 铝基板与驱动采用分体式，驱动与 LED 光源之间采用焊接方式连接。例如授权公告日为 2013 年 8 月 15 日， 专利号为 201320502252.5 的中国发明专利揭示了一种 LED 球泡灯构件。该 LED 球泡灯构件包括灯罩、散热器、LED 光源板、灯头，所述散热器包括散热基座、散热叶片和中空管， 中空管位于散热基座下方并与散热基座连接，中空管内部形成容置 LED 驱动电源的空间。

请参考图3，该基板20为铝基板，该基板20设有第一连接端21与第二连接端22，该第一电极61与该第一连接端21电连接，该第二电极62为杆状结构，该第二连接端22包括连接部222及接触部221，该连接部222与该基板20上的电子元件电连接，该接触部221与该第二电极62的一端电连接。
该第一电极61还包括绝缘套64，该绝缘套64固定在该第一电极61的底部，该绝缘套64的中部设有收容孔（图未示），该第二电极62设置在该收容孔内。该绝缘套64的中部环绕该收容孔设有支撑套63，该支撑套63的内壁对应该第二电极62设置，该第二电极62的外壁设有倒钩（图未示），该倒钩与该支撑套63的内壁扣接。该第二连接端22设置在该基板20的背面，该接触部221包括一对相对设置的弹片2211，该第二电极62的一端插设在该两个弹片2211之间实现电连接。该连接部222为片状结构，该连接部222与该接触部221一体成型，该连接部222上设有连接脚2221，所述连接脚2221固定在该基板20的背面。

工作时，该基板20背面的第一连接端21与该散热件80的顶板81电连接，由于该散热件80的侧壁82与该第一电极61电连接，因此该基板20上的第一连接端21能够与该第一电极61实现电连接。设置在该基板20背面的第二连接端22通过在接触部221相对设置两个弹片2211，使该杆状结构的第二电极62的一端能够插设在这两个弹片2211之间从而使该第二连接端22与该第二电极62实现电连接。这样，该第一连接端21与第二连接端22就可以通过线路层对该基板20上的电子元件，如LED光源30，驱动IC芯片40灯进行供电。
综上所述，该灯头电连接结构100通过在该基板20上同时设有驱动IC芯片40和LED光源30，并在该基板20上设置与该基板20上的电子元件电连接的第一连接端21与第二连接端22，使灯头第一电极61与该第一连接端21电连接，灯头第二电极62与该第二连接端22电连接，从而免去了实现电连接时所需要的电源线设置，使得在固定基板的同时实现驱动电路与灯头的电连接，简化了结构，具有结构简单的优点。而且在自动化组装时，该支撑套63能对该第二电极62进行导向，只要插入该第二电极62就能实现电连接，使得该灯头电连接结构100具有便于自动化组装的优点。另外，该第二连接端22设置在该基板20的背面，不会影响该基板20正面的LED光源30的设置，从而为整灯的光学设计留下了较大的空间。该灯头60不必局限于螺口灯头，其他灯头也可以为其他灯头，如插口灯头等。只要将该第二电极62设置为杆状结构即可。
