LED lamp bulb with conductive element inserted in self-locking element

A waterproof lamp bulb, comprising:

• a hollow lampshade defining a cavity with an open end;
• a circuit board arranged in the cavity of the lampshade, and including a neutral wire inlet port for connecting with a neutral wire, and a live wire inlet port for connecting with a live wire of a power supply, both wire inlet ports arranged on a first end of the circuit board;
• a light emitting element arranged on a second end of the circuit board;
• a silicone washer having a through hole, wherein the silicone washer is connected to the open end of the lampshade and is fixedly connected to the circuit board to fix the circuit board in the cavity;
• a lamp holder including an avoidance hole corresponding with the through hole of the silicone washer, wherein the lamp holder is mounted around an outer wall of the lampshade at the open end, to fasten the silicone washer on the lampshade in a waterproof manner;
• a self-locking element fixed to the live wire inlet port of the circuit board;
• a rod-shaped first conductive element having first and second ends, the first end inserted through the through hole of the silicone washer with an interference fit and received in the self-locking element, the second end passes through the avoidance hole, such that an inner edge of the avoidance hole is spaced from the second end of the first conductive element;
• and
• a second conductive element made of conductive wire, and including a first end fixedly connected to the neutral wire inlet port of the circuit board, and a second end electrically connected to the lamp holder.
