[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0023] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention. Example 1

[0024] The lampshade 2 and the base are generally screw-mounted by a screw thread, which makes it very inconvenient to disassemble or install the lampshade 2, especially when inspecting and maintaining the LED lamp mainboard 11 inside.

[0025] To do this, see Figure 1-2 The utility model provides a high PF non-stroboscopic LED bulb, comprising: a bulb base 1, an LED lamp mainboard 11 is fixedly connected to the inside of the bulb base 1, a limiting ring 12 is fixedly connected to the inner wall of the bulb base 1, a lampshade 2 is movably overlapped at the bottom of the limiting ring 12, and the bulb base 1 is movably sleeved on the top of the lampshade 2;

[0026] It also includes a clamping structure 3 which is installed on the bulb base 1 and the lampshade 2 . The clamping structure 3 can facilitate the assembly and disassembly of the lampshade 2 .

[0027] Further Figure 1-2 As shown, it is worth explaining in detail that in order to facilitate the rapid disassembly of the lampshade 2 on the bulb base 1, a clamping structure 3 is provided, including a rotating ring 31 rotatably connected to the outside of the bulb base 1, and a plurality of inclined grooves 32 are provided on the rotating ring 31. The inclined grooves 32 are movably overlapped with transmission columns 33, and the bottom ends of the transmission columns 33 are fixedly connected with moving blocks 34. The moving blocks 34 are movably fitted to the outside of the bulb base 1, and the moving blocks 34 are fixedly connected to a plug column 36 on a side wall of the outside of the bulb base 1. The plug columns 36 are movably inserted into the bulb base 1, and the outside of the lampshade 2 is provided with a socket 37 matching the plug column 36. The moving blocks 34 are movably sleeved on the outside of the L-shaped guide rod 35, and the L-shaped guide rod 35 is fixedly connected to the outside of the bulb base 1. The side wall of the moving block 34 away from the plug column 36 is fixedly connected to the L-shaped guide rod 35 through a spring 38.

[0028] The width of the inclined slot 32 is equal to the diameter of the transmission column 33 , and both ends of the spring 38 are fixed and cannot be disassembled. Example 2

[0029] like Figure 3As shown, in the second embodiment, other structures remain unchanged. The utility model provides another elastic connection structure, which includes an inverted V-shaped spring piece 39 movably inserted on the moving block 34 and the corresponding L-shaped guide rod 35, and an oblique slot matching the inverted V-shaped spring piece 39 is respectively provided on a side wall of the moving block 34 away from the plug column 36 and a side wall of the L-shaped guide rod 35 toward the outside of the bulb base 1.
