[0001] Cross-references to related applications
[0002] This application claims priority to Chinese patent application No. 202420972328.9, filed on May 7, 2024, entitled "LED Bead Bracket, LED Beads and Display Module", which is incorporated herein by reference in its entirety. Technical Field
[0003] This application relates to the field of LED display technology, and in particular to a lamp bead bracket, LED lamp beads, and display module. Background Technology
[0004] With the rapid development of the LED industry, market customers have increasingly higher requirements for display screens, especially rental screens. LED displays are generally composed of several LED display modules, which in turn are formed by several LED chips. In recent years, market customers have placed increasingly higher demands on the protection capabilities of these LED chips. Existing LED chips typically consist of a chip body and a chip support. The chip body is mounted on the chip support, which is then fixed to the LED board by soldering to pads. Occasionally, during use, the pads may fall off, resulting in the chip falling out, indicating relatively poor protection capabilities for the LED chips. Summary of the Invention
[0005] The main purpose of this application is to provide a lamp bead bracket, LED lamp beads, and display module, which aims to improve the protection capability of LED lamp beads.
[0006] To achieve the above objectives, this application proposes a lamp bead bracket for use with LED lamp beads, the lamp bead bracket comprising:
[0007] The lamp body includes at least two lamp body parts and at least one bridging part, the bridging part being disposed between two adjacent lamp body parts and connecting the two adjacent lamp body parts;
[0008] At least two lamp cups, one of which is disposed on the surface of one of the lamp bodies; each of the lamp cups has a receiving groove on its first surface for placing the lamp body of the LED lamp bead;
[0009] The second side of the bridge connection is provided with a dotted adhesive portion for fixing the bridge connection.
[0010] In one embodiment, a groove is provided on the second surface of the bridging portion, and the groove forms the dispensing portion.
[0011] In one embodiment, two grooves are provided, which are arranged opposite to each other and respectively penetrate opposite sides of the bridge connection; and / or,
[0012] The groove is elongated and extends along the length of the bridge connection, passing through the opposite ends of the bridge connection.
[0013] In one embodiment, the two opposite sides of the bridge connection are both concave arc surfaces.
[0014] In one embodiment, the bridge connection is provided with reinforcing ribs inside.
[0015] In one embodiment, when the lamp bead bracket is placed horizontally, the projected area of the lamp cup on the horizontal plane is smaller than the projected area of the corresponding lamp body on the horizontal plane, and the lamp body is black.
[0016] In one embodiment, the outer side of the lamp cup forms a stepped structure with the surface of the lamp body.
[0017] In one embodiment, face mask fasteners are provided on both opposite side walls of the lamp body.
[0018] This application also proposes an LED lamp bead, which includes a lamp bead body and a lamp bead bracket as described above, wherein the lamp bead body is disposed within a receiving groove of the lamp cup in the lamp bead bracket.
[0019] This application also proposes a display module, which includes a lamp board and LED beads as described above. The LED beads are fixed on the lamp board by the lamp bead bracket, and the adhesive part of the bridging portion of the lamp bead bracket is fixed on the lamp board by adhesive dispensing.
[0020] The technical solution of this application includes a lamp bead bracket comprising a lamp body and at least two lamp cups. The lamp body includes at least two lamp body portions and at least one bridging portion. The bridging portion is disposed between two adjacent lamp body portions and connects the two adjacent lamp body portions. One lamp cup is correspondingly disposed on the surface of one lamp body portion. Each lamp cup has a receiving groove on its first surface for placing the LED bead body. The bridging portion has an adhesive dotting portion on its second surface for fixing the bridging portion. With this configuration, when fixing the lamp bead bracket, the bridging portion can be fixed to the lamp board or other objects by applying adhesive through the adhesive dotting portion, further strengthening the stability of the lamp bead bracket and thus improving the protection capability of the LED bead. Furthermore, since the surface of the bridging portion facing away from the lamp cup is not soldered to the solder pads of the lamp board, but is directly fixed to the surface of the lamp board or other objects by adhesive dotting, the phenomenon of the LED bead falling off due to solder pad detachment during use can be effectively avoided.

[0033] In order to effectively solve the problem that the solder pads and LED beads occasionally fall off during the use of existing LED beads, this application proposes an LED bead bracket 100, which aims to improve the protection capability of LED beads.
[0034] Please refer to Figures 1 and 2. In one embodiment of this application, the LED bead bracket 100 includes a lamp body 1 and at least two lamp cups 2. The lamp body 1 includes at least two lamp body portions and at least one bridging portion 12. The bridging portion 12 is disposed between two adjacent lamp body portions and connects the two adjacent lamp body portions. One lamp cup 2 is correspondingly disposed on the surface of one lamp body portion. Each lamp cup 2 has a receiving groove 21 on its first surface for placing the LED bead body. The second surface of the bridging portion 12 has a dotted adhesive portion 14 for fixing the bridging portion 12.
[0035] Specifically, the number of lamp body parts can be two or more. When there are two lamp body parts, there is one bridging part 12, meaning the lamp body 1 includes a first lamp body part 11, a bridging part 12, and a second lamp body part 13 connected sequentially. When there are two or more lamp body parts, the number of bridging parts 12 is at least one less than the number of lamp body parts. The bridging part 12 is located between and connected to two adjacent lamp body parts. Correspondingly, the number of lamp cups 2 is the same as the number of lamp body parts. One lamp cup 2 is provided on the surface of one lamp body part, and the lamp cup 2 is located on the same side surface of the lamp body part. Furthermore, each lamp cup 2 has a receiving groove 21 on its first surface for placing the lamp bead body of the LED lamp bead. The lamp body parts, bridging parts 12, and lamp cups 2 can all be made of polyphthalamide (PPA) and are all injection molded. Optionally, the lamp body parts and bridging parts 12 are injection molded into an integral structure of the lamp body 1, and the lamp body 1 and lamp cups 2 are injection molded into an integral structure. During injection molding, the lamp cup 2 has a receiving groove 21 formed on its surface. During injection molding of the lamp body 1, a dispensing portion 14 is reserved on the second side of the bridging portion 12. Subsequently, the bridging portion 12 can be fixed by dispensing through the dispensing portion 14 using a dispensing process, thereby further strengthening the sturdiness of the lamp bead bracket 100 and improving the protection capability of the LED lamp bead. The lamp bead body can be a light-emitting component, such as an LED light-emitting chip, including at least one of red LED chips, green LED chips, and blue LED chips, or other light-emitting chips.
[0036] The technical solution of this application provides an adhesive dispensing part 14 on the second side of the bridging part in the lamp body 1. This dispensing part 14 allows the bridging part 12 to be fixed to an object such as a lamp board using adhesive, further strengthening the stability of the LED bead bracket 100 and thus improving the protection capability of the LED beads. Furthermore, since the surface of the bridging part 12 facing away from the lamp cup 2 is not soldered to the solder pads of the lamp board, but is directly fixed to the surface of the lamp board or other object using adhesive, the phenomenon of LED beads falling off due to solder pad detachment during use can be effectively avoided.
[0037] In a specific embodiment of this application, the lamp bead bracket 100 adopts a two-in-one structure, that is, the lamp body 1 includes a first lamp body part 11, a bridging part 12 and a second lamp body part 13 connected in sequence. Two lamp beads are provided, and two lamp cups 2 are respectively provided on the same side surface of the first lamp body part 11 and the second lamp body part 13. The first surface of the two lamp cups 2 is provided with a receiving groove 21 for placing the lamp bead body, and the second surface of the bridging part 12 is provided with an adhesive dispensing part 14.
[0038] It should be noted that the length direction of the bridge connecting part 12 is from the first lamp body part 11 to the second lamp body part 13. The distance between the first lamp body part 11 and the second lamp body part 13 can be determined according to the actual requirements of the display module, and is not limited here.
[0039] As shown in Figure 2, in one embodiment of this application, a groove is provided on the second surface of the bridging portion 12, and the groove forms the dispensing portion 14. In this embodiment, the dispensing portion 14 is configured as a groove structure to facilitate the dispensing and fixing operation.
[0040] Furthermore, in order to further enhance the robustness of the LED bead bracket 100 and thus further improve the protection capability of the LED bead, the adhesive dispensing part 14 is set to two or more, that is, the groove is set to two or more.
[0041] Optionally, two grooves are provided, which are arranged opposite to each other and pass through the opposite sides of the bridge connection 12. This not only facilitates the dispensing operation from the side of the bridge connection 12, but also further strengthens the sturdiness of the lamp bead bracket 100.
[0042] Furthermore, the groove is elongated and extends along the length of the bridge portion 12, passing through both ends of the bridge portion 12. With this design, the area of the groove is relatively large, that is, the fixing area of the bridge portion 12 is relatively large, which can further strengthen the sturdiness of the LED bead bracket 100, thereby further improving the protection capability of the LED bead, and also facilitating the dispensing operation.
[0043] As shown in Figures 1 to 3, in one embodiment of this application, the two opposite sides of the bridge connecting portion 12 are both concave arc surfaces. This design can save some materials and reduce the manufacturing cost of the lamp bead bracket 100. At the same time, this structural design also facilitates the dispensing operation.
[0044] It should be noted that the surface of the bridge connecting part 12 facing the lamp cup 2 is also provided with a long strip groove (not shown), and the surface of the bridge connecting part 12 facing away from the lamp cup 2 is provided with a circular groove. This design can save some material and reduce the manufacturing cost of the lamp bead bracket 100. In addition, some raised rib structures are provided on the surface of the bridge connecting part 12 facing away from the lamp cup 2, which facilitates mold forming and ensures good structural strength of the lamp bead bracket 100.
[0045] As shown in Figures 3 and 4, in one embodiment of this application, a reinforcing rib 121 is provided inside the bridge connection portion 12. The reinforcing rib 121 can enhance the structural strength of the bridge connection portion 12, thereby ensuring the stability of the LED bead bracket 100 and improving the protection capability of the LED bead, effectively preventing the LED bead from falling off during use.
[0046] As shown in Figure 4, in one specific embodiment of this application, the reinforcing rib 121 is made of copper sheet and is generally elongated, extending along the length of the bridge connection 12. The reinforcing rib 121 includes a first segment, a second segment, and a third segment connected together. The first and third segments are elongated sheets, while the second segment is an arc-shaped sheet, serving as a transition connection between the first and third segments. This structural design effectively strengthens the structural strength of the bridge connection 12. Of course, in other specific embodiments, the reinforcing rib 121 can also have other reasonable shapes, or multiple separate reinforcing ribs 121, as long as they can enhance the structural strength of the bridge connection 12, all are within the protection scope of this application.
[0047] As shown in Figure 1, in one embodiment of this application, when the LED bead bracket 100 is placed horizontally, the projected area of the lamp cup 2 on the horizontal plane is smaller than the projected area of the corresponding lamp body on the horizontal plane, and the lamp body appears black. This embodiment adopts a design of narrow lamp cup 2 and wide lamp body. When LED beads are used in a display module, the black background area of the display module can be increased, thereby improving contrast and enhancing the competitiveness of the product.
[0048] It should be noted that in the embodiment of the lamp bead bracket 100 with a two-in-one structure, the projected area of the lamp cup 2 corresponding to the first lamp body part 11 on the horizontal plane is smaller than the projected area of the first lamp body part 11 on the horizontal plane, and the projected area of the lamp cup 2 corresponding to the second lamp body part 13 on the horizontal plane is smaller than the projected area of the second lamp body part 13 on the horizontal plane.
[0049] Furthermore, the outer surface of the lamp cup 2 forms a stepped structure with the surface of the lamp body 1. Specifically, when the outer contour of the lamp cup 2 is square or other quadrilateral, all four outer surfaces form a stepped structure with the surface of the lamp body 1; when the lamp cup 2 is circular, all its outer surfaces form a stepped structure with the surface of the lamp body 1; when the outer contour of the lamp cup 2 is triangular, three of its outer surfaces form a stepped structure with the surface of the lamp body 1; and when the outer contour of the lamp cup 2 is any other reasonable shape, all its outer surfaces form a stepped structure with the surface of the lamp body 1. This arrangement can further improve the contrast. It should be noted that the size of the lamp cup 2 can be determined according to the display module requirements of the application and is not limited here.
[0050] As shown in Figure 1, in one embodiment of this application, face mask fasteners 15 are provided on both opposite side walls of the lamp body 1. The face mask fasteners 15 can be fastening grooves or fastening platforms, and are not limited here. This design allows the face mask 200 to be fixed with the face mask 200 by means of snap-fit 201, which is relatively simple to operate and does not require screw fixing, effectively avoiding the phenomenon of warping, bulging and shadowing of the face mask 200 that is prone to occur when fixing with screws.
[0051] It should be noted that in the embodiment of the LED bead holder 100 with a two-in-one structure, both the side wall of the first lamp body portion 11 away from the bridge portion 12 and the side wall of the second lamp body portion 13 away from the bridge portion 12 are provided with a cover fastener 15. In the embodiment of the LED bead holder 100 with an N-in-one structure, both outer walls of the lamp body portions at both ends of the lamp body 1 are provided with a cover fastener 15.
[0052] This application also proposes an LED lamp bead, which includes a lamp bead body and a lamp bead bracket 100. The specific structure of the lamp bead bracket 100 is as described in the above embodiments. Since this LED lamp bead adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The lamp bead body is disposed within the receiving groove 21 of the lamp cup 2 in the lamp bead bracket 100. Optionally, the lamp bead body is fixed in the receiving groove 21 by adhesive, which is simple to operate and relatively secure.
[0053] In this application, the LED bead is connected to the cover 200 by a snap-fit connection on the side wall of the bead holder 100, rather than directly snap-fitting the bead body to the cover 200. This effectively avoids damage to the bead body due to compression during assembly and provides better protection for the bead body.
[0054] This application also proposes a display module, which includes a lamp board and LED beads. The specific structure of the LED beads is as described in the above embodiments. Since this display module adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The lamp board is a PCB board, and the LED beads are fixed to the lamp board by a bead bracket 100. Furthermore, the adhesive dispensing portion 14 of the bridge connection portion 12 in the bead bracket 100 is fixed to the lamp board by adhesive dispensing. This further strengthens the robustness of the bead bracket 100, thereby improving the protection capability of the LED beads and ensuring the stability and reliability of the display module.
[0055] Further, as shown in Figures 5 and 6, in one embodiment of this application, the display module further includes a face mask 200. The face mask 200 is provided with mounting holes 202 for assembling the LED bead bracket 100. The inner wall of the mounting hole 202 is provided with corresponding snap fasteners 201 adapted to the face mask fasteners 15. During assembly, the face mask fasteners 15 on both sides of the lamp body 1 in the LED bead bracket 100 are snapped together with the snap fasteners 201 on the inner wall of the mounting hole 202. The lamp cup 2 is located inside the mounting hole 202 and is at least partially exposed outside the mounting hole 202. The face mask 200 and the LED bead bracket 100 are connected by snap fasteners, which is simpler to operate and more secure. Compared with screw fixing, it can effectively avoid the phenomenon of bulging shadows on the face mask 200 that is prone to occur when screw fixing.
[0056] It should be noted that the mask fastener 15 can be a fastening groove, a fastening platform, or other reasonable structure. Correspondingly, the buckle 201 can be a fastening groove, a fastening platform, or other reasonable structure, as long as the two cooperate to achieve a fastening connection. Optionally, one of the mask fastener 15 and the buckle 201 can be a fastening groove, and the other can be a fastening platform.
[0057] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
