[0033] In order to effectively solve the problem of occasional soldering pad falling and lamp bead falling during use of existing LED lamp beads, the utility model proposes a lamp bead bracket 100, which aims to enhance the protection capability of the LED lamp beads.
[0034] See also Figure 1 and Figure 2 In one embodiment of the utility model, a lamp bead holder 100 includes a lamp body 1 and at least two lamp cups 2. The lamp body 1 includes at least two lamp body parts and at least one bridge part 12. The bridge part 12 is arranged between two adjacent lamp body parts and connects the two adjacent lamp body parts. One lamp cup 2 is correspondingly arranged on the surface of one lamp body part; a surface of each lamp cup 2 facing away from the lamp body part is provided with a receiving groove 21 for placing the lamp bead body of the LED lamp bead; a surface of the bridge part 12 facing away from the lamp cup 2 is provided with a glue part 14 for fixing the bridge part 12.
[0035] Specifically, the number of lamp body parts can be two or more. When the number of lamp body parts is two, the bridge part 12 is one, that is, the lamp body 1 includes a first lamp body part 11, a bridge part 12 and a second lamp body part 13 connected in sequence; when the number of lamp body parts is more than two, the number of bridge parts 12 is at least one less than the number of lamp body parts, and the bridge part 12 is located between two adjacent lamp body parts and connected thereto. 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 cups 2 are located on the same side surface of the lamp body part, and each lamp cup 2 is provided with a receiving groove 21 on the surface facing away from the lamp body part, for placing the lamp bead body of the LED lamp bead. The materials of the lamp body, the bridge part 12 and the lamp cup 2 can all be selected as polyphthalamide (PPA), and are all injection molded. Optionally, the lamp body and the bridge part 12 are injection molded into a lamp body 1 of an integral structure, and the lamp body 1 and the lamp cup 2 are injection molded into an integral structure. When the lamp cup 2 is injection molded, a receiving groove 21 is formed on its surface. When the lamp body 1 is injection molded, a glue spot 14 is reserved on the surface of the bridge part 12 facing away from the lamp cup 2. The bridge part 12 can be fixed by the glue spot 14 using a glue spot process to further strengthen the firmness of the lamp bead bracket 100, thereby improving the protection ability 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 a red light LED chip, a green light LED chip, and a blue light LED chip, or other light-emitting chips.
[0036] The technical solution of the utility model provides a glue point portion 14 on the surface of the bridge portion 12 in the lamp body 1 facing away from the lamp cup 2, and the bridge portion 12 can be fixed to an object such as a lamp board by glue point portion 14, thereby further strengthening the firmness of the lamp bead bracket 100, thereby improving the protection capability of the LED lamp bead. In addition, since the surface of the bridge portion 12 facing away from the lamp cup 2 is not welded to the soldering pad of the lamp board, but is directly glued and fixed to the surface of an object such as a lamp board, the phenomenon of the LED lamp bead falling off due to the soldering pad falling off during the use of the LED lamp bead can be effectively avoided.
[0037] In a specific embodiment of the utility model, the lamp bead holder 100 adopts a two-in-one structure, that is, the lamp body 1 includes a first lamp body part 11, a bridge part 12 and a second lamp body part 13 connected in sequence, and two lamp beads are provided. The two lamp cups 2 are respectively arranged on the same side surface of the first lamp body part 11 and the second lamp body part 13, and the surfaces of the two lamp cups 2 facing away from the lamp body 1 are provided with a receiving groove 21 for placing the lamp bead body, and the surface of the bridge part 12 facing away from the lamp cup 2 is provided with a glue dispensing part 14.
[0038] It should be noted that the length direction of the bridge portion 12 is the direction from the first lamp body 11 to the second lamp body 13. The distance between the first lamp body 11 and the second lamp body 13 can be determined according to the actual requirements of the display module and is not limited here.
[0039] like Figure 2 As shown, in one embodiment of the present invention, a groove is provided on the surface of the bridge portion 12 facing away from the lamp cup 2, and the groove forms a glue dispensing portion 14. In this embodiment, the glue dispensing portion 14 is provided as a groove structure to facilitate glue dispensing and fixing operations.
[0040] Furthermore, in order to further enhance the firmness of the lamp bead bracket 100 and thus further improve the protection capability of the LED lamp bead, two or more glue dispensing parts 14 are provided, that is, two or more grooves are provided.
[0041] Optionally, two grooves are provided, the two grooves are arranged opposite to each other, and respectively penetrate the two opposite side surfaces of the bridge portion 12 , so that it is convenient to perform glue dispensing operation from the side surface of the bridge portion 12 and further enhance the firmness of the lamp bead bracket 100 .
[0042] Furthermore, the groove is in the shape of a long strip, extending along the length direction of the bridge portion 12, and passing through the opposite ends of the bridge portion 12. With such a 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 enhance the firmness of the lamp bead bracket 100, thereby further improving the protection capability of the LED lamp bead, and also facilitates the dispensing operation.
[0043] like Figures 1 to 3 As shown, in one embodiment of the present invention, the two opposite sides of the bridge portion 12 are both concave arc surfaces. Such a configuration can save some materials and reduce the production cost of the lamp bead bracket 100. At the same time, the structural design is also convenient for glue dispensing operation.
[0044] It should be noted that the surface of the bridge portion 12 facing the lamp cup 2 is also provided with a long strip groove (not shown), and the surface of the bridge portion 12 facing away from the lamp cup 2 is provided with a circular groove, and such a design can save some materials and reduce the manufacturing cost of the lamp bead bracket 100. In addition, the surface of the bridge portion 12 facing away from the lamp cup 2 is provided with some convex rib structures, which is beneficial to mold forming on the one hand, and can ensure the good structural strength of the lamp bead bracket 100 on the other hand.
[0045] like Figure 3 and Figure 4As shown, in one embodiment of the utility model, a reinforcing rib 121 is arranged inside the bridge portion 12. The arrangement of the reinforcing rib 121 can strengthen the structural strength of the bridge portion 12, thereby ensuring the arrangement stability of the lamp bead bracket 100, which is beneficial to improving the protection capability of the LED lamp beads and effectively preventing the LED lamp beads from falling off during use.
[0046] like Figure 4 As shown, in a specific embodiment of the present invention, the reinforcing rib 121 is made of metal copper and is punched out of copper sheets. The reinforcing rib 121 is roughly in the shape of a long strip and extends along the length direction of the bridge portion 12. The reinforcing rib 121 includes a first rib segment, a second rib segment and a third rib segment connected to each other. The first rib segment and the third rib segment are in the shape of long strips, the second rib segment is in the shape of an arc sheet, and the second rib segment is a transition connection between the first rib segment and the third rib segment. Such a structural design can effectively strengthen the structural strength of the bridge portion 12. Of course, in some other specific embodiments, the reinforcing rib 121 can also be other reasonable shapes, or multiple reinforcing ribs 121 of split structure, as long as the structural strength of the bridge portion 12 can be strengthened, they are all within the protection scope of the present invention.
[0047] like Figure 1 As shown, in one embodiment of the utility model, when the lamp bead bracket 100 is placed horizontally, the projection area of the lamp cup 2 on the horizontal plane is smaller than the projection area of the corresponding lamp body on the horizontal plane, and the lamp body is black. This embodiment adopts the design of narrow lamp cup 2 and wide lamp body. When the LED lamp bead is applied to the display module, the black background area of the display module can be increased, thereby improving the contrast and enhancing the competitiveness of the product.
[0048] It should be noted that, in the embodiment of the lamp bead holder 100 adopting a two-in-one structure, the projection area of the lamp cup 2 corresponding to the first lamp body 11 on the horizontal plane is smaller than the projection area of the first lamp body 11 on the horizontal plane, and the projection area of the lamp cup 2 corresponding to the second lamp body 13 on the horizontal plane is smaller than the projection area of the second lamp body 13 on the horizontal plane.
[0049] Furthermore, the outer side surface of the lamp cup 2 forms a step structure with the surface of the lamp body 1. Specifically, when the outer contour of the lamp cup 2 is a square or other quadrilateral, its four outer side surfaces all form a step structure with the surface of the lamp body 1; when the lamp cup 2 is circular, all of its outer side surfaces form a step structure with the surface of the lamp body 1; when the outer contour of the lamp cup 2 is a triangle, its three outer side surfaces all form a step structure with the surface of the lamp body 1; when the outer contour of the lamp cup 2 is other reasonable shapes, all of its outer side surfaces form a step structure with the surface of the lamp body 1. Such a setting can further improve the contrast. It should be noted that the size of the lamp cup 2 can be determined according to the requirements of the display module of the application, and is not limited here.
[0050] like Figure 1 As shown, in one embodiment of the utility model, the two opposite side walls of the lamp body 1 are provided with mask buckle positions 15. The mask buckle position 15 can be a buckle groove or a buckle platform, which is not limited here. Such a design can be fixed with the mask 200 by means of a buckle 201, which is relatively simple to operate and does not require screw fixation, effectively avoiding the phenomenon of warping and bulging shadow of the mask 200 that is easy to occur when screw fixation is used.
[0051] It should be noted that in the embodiment of the lamp bead holder 100 adopting a two-in-one structure, the side wall of the first lamp body 11 away from the bridge part 12 and the side wall of the second lamp body 13 away from the bridge part 12 are both provided with mask buckles 15. In the embodiment of the lamp bead holder 100 adopting an N-in-one structure, the outer side walls of the lamp body at both ends of the lamp body 1 are both provided with mask buckles 15.
[0052] The utility model 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 refers to the above embodiment. Since the LED lamp bead adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the lamp bead body is arranged in 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 gluing, which is simple to operate and relatively firm.
[0053] The LED lamp bead of the utility model is snap-connected with the mask 200 via the mask snap position 15 on the side wall of the lamp bead bracket 100, rather than directly snap-connecting the lamp bead body with the mask 200. This can effectively prevent the lamp bead body from being squeezed and damaged during the assembly process, and provides better protection for the lamp bead body.
[0054] The utility model also proposes a display module, which includes a lamp board and LED lamp beads. The specific structure of the LED lamp beads refers to the above embodiment. Since the display module adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the lamp board is a PCB board, and the LED lamp beads are fixed on the lamp board through the lamp bead bracket 100, and the glue dispensing part 14 of the bridge part 12 in the lamp bead bracket 100 is fixed on the lamp board by glue dispensing. In this way, the firmness of the lamp bead bracket 100 can be further strengthened, thereby improving the protection ability of the LED lamp beads and ensuring the stability and reliability of the display module.
[0055] Furthermore, if Figure 5 and Figure 6As shown, in one embodiment of the utility model, the display module also includes a mask 200, and the mask 200 is provided with an assembly hole 202 for assembling the lamp bead bracket 100, and the inner wall of the assembly hole 202 is correspondingly provided with a buckle 201 adapted to the mask buckle position 15. During assembly, the mask buckle positions 15 on the two side walls of the lamp body 1 in the lamp bead bracket 100 are buckled and connected with the buckle 201 on the inner wall of the assembly hole 202, and the lamp cup 2 is located in the assembly hole 202 and at least partially exposed to the assembly hole 202. The buckle connection method is adopted between the mask 200 and the lamp bead bracket 100, which is relatively simple to operate and the connection is relatively firm. Compared with screw fixing, it can effectively avoid the phenomenon of bulging shadow of the mask 200 that is easy to appear when screw fixing.
[0056] It should be noted that the mask buckle position 15 can be a buckle slot, a buckle platform or other reasonable structures, and correspondingly, the buckle 201 can be a buckle slot, a buckle platform or other reasonable structures, as long as the two cooperate to achieve a buckle connection. Optionally, one of the mask buckle position 15 and the buckle 201 is a buckle slot, and the other is a buckle platform.
[0057] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
