[0002] LED beads for displays are miniature light-emitting elements specifically designed for image display. Traditional LED beads consist of a frame, a light-emitting component, and a lens cover. The lens cover improves the luminous efficiency of the LED beads. Through the focusing effect of the lens, the light can be made more concentrated and uniform, improving the display effect of the screen. However, when installing the beads, if the installation tool scratches the surface of the lens cover, it may render the beads unusable, resulting in a waste of resources. Therefore, this solution proposes an anti-sulfurization LED bead for displays to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-4 The LED beads for a sulfur-resistant display screen shown include:

[0024] Support frame 1;

[0025] Light-emitting component 2 is disposed on the top of support frame 1;

[0026] Lens cover 3, which is mounted on top of support frame 1;

[0027] Mounting component 4 includes a first threaded ring 401 fixedly connected to the bottom of the lens cover 3, a second threaded ring 404 sleeved on the outer wall of the support frame 1, a connecting ring 402 threadedly sleeved on the outer wall of the second threaded ring 404, and the connecting ring 402 threadedly sleeved on the outer wall of the first threaded ring 401. A limiting member 5 is provided at the connection between the first threaded ring 401 and the support frame 1.

[0028] It should be noted that the lens cover 3 is used to improve the luminous efficacy of the LED beads. Through the focusing effect of the lens, the light can be more concentrated and uniform, improving the display effect of the screen. The cross-section of the first threaded ring 401 and the second threaded ring 404 are both set as annular, and both have threads on their outer walls. The top of the connecting ring 402 has a threaded groove. The first threaded ring 401 and the second threaded ring 404 are threadedly connected to the top of the connecting ring 402 through the threaded groove. The second threaded ring 404 is fixedly sleeved on the outer wall of the support frame 1. The connecting ring 402 is connected to the support frame 1 through the second threaded ring 404, and the connecting ring 402 is connected to the lens cover 3 through the first threaded ring 401. This design allows the lens cover 3 to be disassembled on the support frame 1. When the lens cover 3 is damaged, it can be directly replaced, avoiding the situation where the entire lens cover needs to be replaced due to damage to the lens cover 3.

[0029] Specifically, the top of the support frame 1 is provided with an insertion groove 403, and the first threaded ring 401 is inserted and connected inside the insertion groove 403.

[0030] It should be noted that the insertion groove 403 is adapted to the first threaded ring 401. When the first threaded ring 401 moves downward, the bottom end of the first threaded ring 401 fits against the inner wall of the bottom end of the insertion groove 403. The insertion groove 403 blocks the first threaded ring 401 from moving further, thereby limiting the movement distance of the first threaded ring 401.

[0031] Specifically, the limiting component 5 includes limiting blocks 501 symmetrically fixedly connected to the inner walls on both sides of the insertion groove 403, and limiting grooves 502 symmetrically opened on the inner walls on both sides of the first threaded ring 401, with the limiting blocks 501 inserted into the inside of the limiting grooves 502.

[0032] It should be noted that the number of limiting blocks 501 is at least two, and the number of limiting slots 502 is the same as the number of limiting blocks 501, and their positions correspond. When the first threaded ring 401 is inserted into the insertion slot 403, the limiting block 501 is inserted into the limiting slot 502. The first threaded ring 401 cannot rotate in the insertion slot 403 due to the obstruction of the limiting block 501, and the first threaded ring 401 restricts the rotation, thus preventing the lens cover 3 from rotating.

[0033] Specifically, the light-emitting component 2 includes an LED chip 204 that is inserted and connected to the top of the support frame 1. The output end of the LED chip 204 is electrically connected to a wire 203. One end of the wire 203 is electrically connected to a lamp holder 202. The input end of the LED chip 204 is electrically connected to a pin 201. A silicon nitride thin film layer 205 is disposed on the top of the LED chip 204. The lamp holder 202 and the wire 203 are both inserted and connected to the middle of the silicon nitride thin film layer 205. A phosphor layer 206 is disposed on the top of the silicon nitride thin film layer 205. The lamp holder 202 and the wire 203 are both inserted and connected to the bottom of the phosphor layer 206.

[0034] It should be noted that by covering the outer surface of the LED chip 204 with a silicon nitride thin film layer 205, the corrosion of sulfides is effectively blocked, improving the stability and lifespan of the LED bead; at the same time, the setting of the fluorescent adhesive layer 206 enhances the luminous efficiency of the LED chip 204 and is flush with the upper surface of the support frame 1; the wire 203 passes through the silicon nitride thin film layer 205 and is electrically connected to the LED chip 204, ensuring the stability of the electrical performance of the LED bead.

[0035] Specifically, a heat-conducting plate 6 is provided at the bottom of the LED chip 204, and the pins 201 are inserted and connected in the middle of the heat-conducting plate 6.

[0036] It should be noted that the heat-conducting plate 6 is made of aluminum oxide, which has both insulating and thermal conductivity properties, and is used to transfer and dissipate the heat generated by the LED beads.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
