In this embodiment, the light-emitting element 4 can be an LED lamp. The number and specifications of the light-emitting elements 4 are set according to actual needs.

[0030] The light guide assembly 3 includes a fixing ring 5, a light guide column 6 and a light shielding sleeve 7. The light shielding sleeve 7 is fixedly connected to the connecting part 2 through the fixing ring 5. One end of the light shielding sleeve 7 is connected to the connecting part 2, and the other end is in contact with the PCB board 9. The light shielding sleeve 7 includes a reducing section 8. The angle between the side surface and the center line of the reducing section 8 can be 15°, 16°, 17°, 18° or 20°, etc. The reducing section 8 is used to gather the light source. The light guide column 6 is used to transmit the light source of the light-emitting component 4 to the display panel 1. A limit head 61 is provided on the light guide column 6. The limit head 61 is used to prevent the light guide column 6 from moving downward. The surface of the limit head 61 is set to be spherical. The protective plate on the display panel 1 prevents the light guide column 6 from sliding off the display panel 1. In this embodiment, the fixing ring 5 can be made of rubber or silicone, and the light guide column 6 can be made of polycarbonate, general-grade polystyrene or polymethyl methacrylate.

[0031] The connecting part 2 is provided with a limiting surface 23, a through hole 1 22 and four reinforcement members 21. A portion of the reinforcement member 21 is connected to the connecting part 2, and a portion is connected to the display panel 1. The limiting surface 23 is used to limit the position of the fixing ring 5 on the connecting part 2. The shading sleeve 7 is provided with a through hole 2 71. The through hole 1 22 and the through hole 2 71 form an accommodating cavity for accommodating the light guide column 6.
