LED (Light emitting diode) lamp holder structure

The utility model provides a LED (Light emitting diode) lamp holder structure, the fine length to the insulator of lamp holder of this kind of structure is controlled to mounting structure to dirver circuit board simplifies. It includes lamp base, the bench insulator, electrically conductive head of screw thread and electrically conductive cap, the bench insulator is inside cavity both ends open -ended column part, the one end and the lamp base of bench insulator are connected, the other end and the electrically conductive head of screw thread of bench insulator pass through threaded connection, inside the form installation cavity that be used for install dirver circuit board of back at the electrically conductive head of screw is connected with the electrically conductive head of screw to the bench insulator, dirver circuit board's shape is circular, dirver circuit board's lower surface supports and leans on on the terminal surface of bench insulator, components and parts contact with the top inner wall of t
