[0002] LED bulbs are lighting products that use light-emitting diodes as light sources. They look similar to traditional incandescent bulbs, but their internal structure and light-emitting principle are completely different. With advantages such as high efficiency, energy saving, long life, and environmental protection, they have gradually replaced incandescent lamps and energy-saving lamps and become the mainstream choice for modern home, commercial, and industrial lighting.

[0003] LED bulbs are mainly composed of the following parts: LED light board, driving power supply, optical lens and lamp holder assembly. The LED light board is the core light-emitting element, usually made of semiconductor materials (such as GaN gallium nitride). It emits light directly after power is turned on, and its efficiency is much higher than that of the tungsten filament of incandescent lamps. The driving circuit is used to convert alternating current (AC) into direct current (DC) suitable for LED operation and provide stable current. The optical lens is used to evenly distribute the light to avoid glare, and at the same time seal the LED light board. The lamp holder assembly is a key component connected to the external power supply and is mainly used for electrical connection and installation.

[0040] The base 50 includes a first sleeve 51, a second sleeve 52 connected to one end of the first sleeve 51, and a stop baffle 53 connected to the second sleeve 52. The stop baffle 53 is distributed around the axis of the second sleeve 52. A through hole 511 is provided on the first sleeve 51. A stop groove 531 is formed on the side of the stop baffle 53 facing away from the first sleeve 51. In addition, an external thread is provided between the end of the second sleeve 52 facing away from the first sleeve 51 and the stop baffle 53.

[0041] The outer cover 60 is in the shape of a hollow trumpet as a whole. Two adjusting plates 64 are arranged opposite to each other on the inner side of the outer cover 60.

During the screwing process of the pressure rod 41, the matching surface 411 on the pressure rod 41 squeezes the first matching end 424 of the push rod 422, so that the convex head 427 of the second matching end 425 extends from the shell body and is stuck on the fixing groove 331 of the contact head 30, and the return spring 423 elastically contracts, thereby achieving the locking and fixing of the contact head 30. During the further screwing process of the pressure rod 41, the bottom of the pressure rod 41 presses the positioning surface 211 on the positioning rod 20, thereby locking the positioning rod 20, so that the single pressure rod 41 can be matched with the locking member 42 to fix the positioning rod 20 and the contact head 30, and the inclined guide surface 212 on the positioning rod 20 can make the pressure rod 41 better stuck in the card slot 21 on the positioning rod 20, reducing the position requirement of the positioning rod 20 when it is initially installed on the insulator 10.
