[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] See also Figure 1-5As shown, an LED lamp base includes a shell 5, a limiting cylinder 4 is fixedly connected to the middle of the shell 5, a movable cylinder 2 is slidably connected to the limiting cylinder 4 along its axial direction, and two metal sheets 1 are fixedly connected to the outer side of the movable cylinder 2 along its axial direction. The two ends of the metal sheet 1 are respectively fixed to the two ends of the movable cylinder 2, and metal springs 10 are fixedly connected to the inner side of the limiting cylinder 4 at positions corresponding to the two metal sheets 1. An elastic member 8 is provided between the movable cylinder 2 and the shell 5, and the elastic member 8 is used to drive the movable cylinder 2 to reset so that the metal sheet 1 is away from the metal spring 10.

[0026] During use, the movable cylinder 2 slides upward under the pressure of the LED lamp 12, the elastic part 8 is compressed, and at the same time the two metal sheets 1 are respectively connected to the two metal springs 10 to supply power to the LED lamp 12 through the metal sheets 1; when the LED lamp 12 is removed, the elastic part 8 pushes the movable cylinder 2 to reset, so that the metal sheet 1 is disconnected from the metal spring 10, and the metal sheet 1 loses power, thereby avoiding safety accidents caused by accidental touch.

[0027] To prevent the movable cylinder 2 from rotating relative to the limiting cylinder 4, a limiting groove 9 is formed on the inner side of the limiting cylinder 4 along its axial direction. A slider 6 is fixedly connected to the outer side of the movable cylinder 2 at a position corresponding to the limiting groove 9. The slider 6 and the limiting groove 9 cooperate to limit the movable cylinder 2, preventing it from rotating relative to the limiting cylinder 4, which would cause the metal sheet 1 and the metal spring 10 to misalign.

[0028] To prevent short circuits, two metal sheets 1 are symmetrically distributed outside the movable cylinder 2. This allows for controlled spacing between the two metal sheets 1 to prevent short circuits. Both metal springs 10 are connected to a power source. Specifically, the two metal springs 10 are connected to the live and neutral wires, respectively.

[0029] To prevent the elastic member 8 from shifting, limiting annular grooves 7 are provided at corresponding positions of the movable cylinder 2 and the housing 5. The limiting annular grooves 7 limit the ends of the elastic member 8, preventing the elastic member 8 from shifting and ensuring that the force applied to each part of the movable cylinder 2 is balanced, so that the movable cylinder 2 can be smoothly rebounded and reset. Preferably, the elastic member 8 is a plastic spring.

[0030] In some embodiments, a plurality of hanging grooves 3 are formed on the outer side of the housing 5 along its circumference, and a hanging block 11 is fixedly connected to the outer side of the LED lamp 12 at a position corresponding to the hanging grooves 3 .

[0031] Specifically, the LED lamp 12 is fixedly connected to a metal column 13 at a position corresponding to the metal sheet 1 .

[0032] During installation, align the metal column 13 with the metal sheet 1, align the hanging block 11 with the hanging slot 3, and rotate the LED lamp 12 along the hanging slot 3 to move the hanging block 11 to the end of the hanging slot 3; in the process of pushing the LED lamp 12 upward, the movable cylinder 2 is forced to move upward, the elastic part 8 is compressed, and the metal sheet 1 is connected to the metal spring 10; when the hanging block 11 moves to the end of the hanging slot 3, the elastic part 8 pushes the movable cylinder 2 to apply pressure to the LED lamp 12 to prevent the hanging block 11 from rotating out of the hanging slot 3.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
