The lamp body and lamp holder of the LED bulb adopt the existing interface methods, namely the screw socket and the socket method (E26\E27\E14\B22, etc.), and even imitate the shape of the incandescent bulb in order to meet people's usage habits. Based on the unidirectional light emitting principle of LED, the designer made changes in the structure of the lamp so that the light distribution curve of the LED bulb basically converges with the point light source of the incandescent lamp. Based on the light-emitting characteristics of LEDs, the structure of LED bulbs is more complex than that of incandescent lamps. It is basically divided into light source, driving circuit, and heat sink. The cooperation of these parts can create LED bulbs with low energy consumption, long life, high luminous efficiency and environmental protection. lamp products. Therefore, LED lighting products are still high-tech lighting products with high technical content at present.

However, the connection between the lamp body and the lamp cap of the existing screw-mounted LED lamps is generally realized by gluing. on the lamp body. Regardless of the existing connection methods between the lamp cap and the lamp body, there is a common shortcoming, that is, the problem of sealing. The sealing of the connection between the screw cap and the lamp body is poor, and usually cannot meet the sealing internal pressure. 1 atmosphere requirement.

In addition, the connection structure between the existing screw lamp cap and the lamp body also has great defects. After the existing lamp wire passes through the wire groove on the lamp body, it cannot be threaded back into the lamp body, and the lamp wire remains in the lamp cap. Next, there is a great security risk.
