[0002] With the development of LED display technology, the application scenarios of LED displays are becoming increasingly widespread. Among these scenarios, many local structures (such as circular pillars) are curved. Therefore, it is necessary to splice LED displays into an outward arc shape to adapt to specific installation scenarios.

[0003] In existing LED arc-shaped modules, the assembly process between the various components of the module requires high precision. After the lamp board and the mask are connected to the bottom shell, defects such as warping or bulging of the lamp board and the mask are prone to occur. This results in the arc-shaped surface of the LED module not being smooth enough, and the waterproof effect of the LED module is not ideal, which affects the display effect of the LED module. Utility Model Content

[0004] The purpose of this utility model is to provide an LED module that ensures that the light panel and the mask remain smooth after being connected to the bottom shell, and prevents the mask from warping or bulging.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: According to one aspect of this utility model, an LED module is provided, the LED module comprising: a base shell having an arc-shaped structure, the two opposite sides of the base shell being a concave surface and a convex surface, respectively; multiple connectors connected to the convex surface, the multiple connectors being spaced apart along the arc-shaped extension direction of the base shell, the extension direction of the connectors being perpendicular to the tangent of the convex surface; a lamp plate connected to the connectors and located on the side of the connectors facing away from the base shell, the lamp plate being arc-shaped and adapted to the convex surface, the lamp plate being used for emitting light; and a face mask connected to the connectors and located on the side of the lamp plate facing away from the connectors, the face mask being arc-shaped and adapted to the convex surface.

[0014] This application also provides an LED display screen, which includes a housing and any of the LED modules mentioned above. The housing is provided with an arc-shaped connecting part, which is used to install the LED module, and the concave surface is attached to the connecting part.

[0015] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects: In this invention, the LED module includes a base shell, connectors, a lamp board, and a faceplate. The base shell has an arc-shaped structure, with concave and convex surfaces on opposite sides. Multiple connectors are provided and connected to the convex surface.

[0030] In existing LED arc-shaped modules, the assembly process between the various components requires high precision. Furthermore, after the lamp board and mask are attached to the base, defects such as warping or bulging can easily occur, resulting in an uneven arc-shaped surface and suboptimal waterproofing, thus affecting the display performance. Therefore, this paper proposes an LED module to address these issues.

[0031] The solution is further illustrated by the following examples: Figure 1 This is a schematic diagram of an LED display screen according to an embodiment of the present invention. Figure 2 yes Figure 1 A top view of the LED display screen. Figure 3 yes Figure 1An exploded view of the LED display screen. In this embodiment, [the view is shown]. Figure 2 The direction perpendicular to the paper is the length direction of the LED display screen.

[0032] Please see Figure 1 , Figure 2 and Figure 3 The LED display screen of this embodiment can be installed on an arc-shaped surface or a cylindrical surface to form an arc-shaped display surface for displaying video or image information.

[0033] Specifically, the LED display screen may include a housing 10 and LED modules 20. The housing 10 is provided with an arc-shaped connecting portion 11, which is used to mount the LED modules 20, allowing the bottom shell 30 to be fitted and fixed to the housing 10. In this embodiment, the housing 10 has an arc-shaped structure, the connecting portion 11 is formed on the outer surface of the housing 10, and the length direction of the connecting portion 11 is the same as the length direction of the housing 10, while the arc-shaped extension direction of the connecting portion 11 is perpendicular to the length direction of the housing 10.

[0034] In some embodiments, multiple LED modules 20 can be connected to the housing 10, and all multiple LED modules 20 can be installed on the connecting part 11 and spliced ​​together to form an integral display screen.

[0035] In other embodiments, the LED display screen may include multiple cabinets 10 and multiple LED modules 20. The multiple cabinets 10 can be spliced ​​together to form a whole, and the connecting parts 11 of the multiple cabinets 10 are located within the same mounting surface. The multiple LED modules 20 can be mounted on the connecting parts 11 of the cabinets 10, and the multiple LED modules 20 can be spliced ​​together so that the display surfaces of the multiple LED modules 20 are located within the same display surface, forming a whole display screen, thereby enabling the LED display screen to meet the display needs of different scenarios.

[0036] It should be noted that the housing 10 can be made of plastic or metal so that the housing 10 can support the LED module 20.

[0037] Figure 4 This is an exploded view of the LED module according to an embodiment of the present invention. Figure 5 yes Figure 4 A schematic diagram of the connectors for the LED module. Figure 6 yes Figure 4 A partial schematic diagram of an LED module. Figure 7 yes Figure 4 A schematic diagram of the bottom shell and connectors of the LED module.

[0038] See Figure 4The LED module 20 may include a base shell 30, a connector 40, a lamp board 50, and a cover 60.

[0039] In this embodiment, the bottom shell 30 has an arc-shaped structure, and the two opposite sides of the bottom shell 30 are a concave surface 31 and a convex surface 32, respectively.

[0040] In some embodiments, the arc-shaped structure of the concave surface 31 is adapted to the arc-shaped structure of the connecting portion 11, so that the concave surface 31 can fit onto the connecting portion 11, thereby connecting the bottom shell 30 to the housing 10.

[0041] In this embodiment, the bottom shell 30 can be connected to the housing 10 with screws, thereby facilitating the installation of the LED module 20 onto the housing 10. Of course, in some other embodiments, the bottom shell 30 can be snapped onto the housing 10 using a snap-fit ​​structure.

[0042] It should be noted that the bottom shell 30 can be made of plastic or metal so that the bottom shell 30 can be used to install the connector 40, the lamp panel 50 and the mask 60 and connect to the housing 10.

[0043] In this embodiment, the connector 40 can be mounted on the convex surface 32, and the extending direction of the connector 40 is perpendicular to the tangential direction of the concave surface 31. Furthermore, multiple connectors 40 are provided, and these multiple connectors 40 are spaced apart along the arcuate extending direction of the bottom shell 30, so that the side of the multiple connectors 40 facing away from the convex surface 32 is located within the same arcuate surface, facilitating the installation of the lamp panel 50 and the mask 60.

[0044] In some embodiments, the lamp panel 50 is used to emit light. The lamp panel 50 is connected to the connector 40 and is located on the side of the connector 40 facing away from the bottom housing 30. The mask 60 is connected to the connector 40 and is located on the side of the lamp panel 50 facing away from the connector 40, that is, in the light emission direction, the mask 60 is located downstream of the lamp panel 50.

[0045] In this embodiment, the lamp panel 50 is configured as an arc shape, which is adapted to the arc shape of the convex surface 32. At the same time, the mask 60 is also configured as an arc shape, which is adapted to the arc shape of the convex surface 32. That is, the shape of the mask 60 is adapted to the shape of the lamp panel 50, so that the mask 60 can fit on the lamp panel 50.

[0046] It should be noted that multiple connectors 40 are spaced apart on the convex surface 32 along the arcuate extension direction of the base shell 30. The side of the connector 40 facing away from the convex surface 32 is located within the same arcuate surface. When the lamp panel 50 and the mask 60 are connected to the connectors 40, it ensures that the lamp panel 50 and the mask 60 are connected to multiple connectors 40 simultaneously, and that the outer surface of the lamp panel 50 and the mask 60 remains smooth after installation, thereby ensuring the display effect. Furthermore, the spacing between adjacent connectors 40 can prevent the lamp panel 50 and the mask 60 from not fitting properly on the mounting surface due to insufficient manufacturing precision of the convex surface 32, thus avoiding phenomena such as warping or bulging.

[0047] In some other embodiments, multiple lamp panels 50 and face shields 60 can be provided, and multiple lamp panels 50 are spliced ​​together and connected to the connector 40 to cover the convex surface 32. At the same time, multiple face shields 60 are spliced ​​together and connected to the connector 40, with one lamp panel 50 corresponding to one face shield 60, so that the face shield 60 can protect the lamp panel 50.

[0048] See Figure 5 and Figure 7 The connector 40 may include a connector 41, a first connecting post 42, a support post 47, and a second connecting post 45.

[0049] The first connecting post 42 and the support post 47 are both connected to the connecting body 41 and extend toward the bottom shell 30. The first connecting post 42 is used to connect to the bottom shell 30 so that the connecting piece 40 can be connected and fixed to the bottom shell 30. The support post 47 is used to abut against the bottom shell 30 to ensure the structural strength of the connecting body 41. At the same time, the second connecting post 45 is connected to the connecting body 41 and extends toward the face mask 60 so that the second connecting post 45 can be used to connect the face mask 60.

[0050] In this embodiment, the second connecting post 45 is formed on the connecting body 41 and is located on the side of the connecting body 41 facing away from the bottom shell 30, so that the second connecting post 45 can be used to connect the face mask 60.

[0051] Meanwhile, the first connecting post 42 is connected to the connecting body 41 and extends toward the bottom shell 30, so that the first connecting post 42 can be used to connect to the convex surface 32 of the bottom shell 30. In this embodiment, the first connecting post 42 is connected to the bottom shell 30 by screws, so that the connecting piece 40 is fastened to the bottom shell 30.

[0052] See Figure 5 The connector 41 may have a first mounting hole 43 and a second mounting hole 44, so that the lamp panel 50 and the mask 60 can be connected to the connector 41.

[0053] Specifically, the connector 41 may be provided with a first mounting hole 43 and a second mounting hole 44 on the side facing the lamp panel 50.

[0054] Specifically, the first mounting hole 43 is used to connect the lamp board 50. Multiple first mounting holes 43 are provided, and the multiple first mounting holes 43 are spaced apart along the length direction of the connector 40, so that multiple connection points are provided between the same connector 40 and the lamp board 50, thereby ensuring that the lamp board 50 is stably connected to the connector 40 and avoiding defects such as warping or bulging of the lamp board 50.

[0055] Meanwhile, the second mounting hole 44 is used to connect the face mask 60. Multiple second mounting holes 44 are provided, and the multiple second mounting holes 44 are spaced apart along the length direction of the connector 40, so that multiple connection points are provided between the same connector 40 and the face mask 60, thereby ensuring that the face mask 60 is stably connected to the connector 40 and avoiding defects such as the face mask 60 lifting or bulging.

[0056] In this embodiment, the lamp plate 50 is connected to the connector 40 by screws. Specifically, the lamp plate 50 is connected to the first mounting hole 43 of the connector 40 by screws, thereby securing the lamp plate 50 to the connector 40. This ensures a tight connection between the lamp plate 50, the connector 40, and the base shell 30, preventing defects such as warping or bulging of the lamp plate 50 during use. Similarly, the face mask 60 is also connected to the second mounting hole 44 of the connector 40 by screws, thereby securing the face mask 60 to the connector 40 and the base shell 30, preventing defects such as warping or bulging of the face mask 60 during use.

[0057] It should be noted that the first mounting hole 43 and the second mounting hole 44 are arranged adjacent to each other, so that the first mounting hole 43 and the second mounting hole 44 form a mounting hole group. The connector 40 is provided with multiple mounting hole groups at intervals along its length, so that the connector 40 can have multiple connection points with the lamp board 50 and the mask 60. This ensures that the lamp board 50 and the mask 60 can be securely connected to the connector 40 at the same time, and avoids defects such as warping and bulging after the lamp board 50 and the mask 60 are connected to the connector 40.

[0058] In some embodiments, the second connecting post 45 protrudes from the side of the connector 40 away from the bottom shell 30, and the second connecting post 45 is provided with a second mounting hole 44, so that the second connecting post 45 can be used to connect the face mask 60.

[0059] Specifically, the connector 40 is provided with a plurality of second connecting posts 45 for connecting the face mask 60, thereby ensuring a secure connection between the face mask 60 and the connector 40.

[0060] In this embodiment, a plurality of second connecting posts 45 are spaced apart along the length of the connecting body 41, and a second mounting hole 44 for connecting the face mask 60 is provided at the end of the second connecting post 45 facing away from the connecting body 41.

[0061] In this embodiment, the lamp plate 50 is provided with a clearance hole 51, which is used to avoid the second connecting post 45, so that the second connecting post 45 passes through the clearance hole 51 and is connected to the mask 60, thereby ensuring that the mask 60 is connected to the connector 40 and located downstream of the light emission direction of the lamp plate 50, and that the mask 60 can protect the lamp plate 50.

[0062] It should be noted that the lamp panel 50 is provided with multiple clearance holes 51, which are respectively set with the second connecting posts 45 on the multiple connectors 40, so that the second connecting posts 45 on the multiple connectors 40 can be connected to the mask 60.

[0063] Figure 8 yes Figure 4 A schematic diagram of the connectors for the LED module.

[0064] See Figure 5 , Figure 7 and Figure 8 The axis of the first connecting post 42 is set at an angle to or parallel to the axis of the second connecting post 45.

[0065] In this embodiment, since the bottom shell 30 is arc-shaped and the convex surface 32 is also arc-shaped, and the connection postures of the connectors 40 at different positions on the convex surface 32 are different, in order to facilitate the installation of the connectors 40 onto the convex surface 32 and ensure that the side of the multiple connectors 40 facing away from the convex surface 32 is located on the same arc-shaped surface, the connection postures of the first connecting post 42 and the connector 41 are different. Thus, the axial direction of the first connecting post 42 is set to be angled or parallel to the axis of the first mounting hole 43 or the axis of the second mounting hole 44, so as to facilitate the installation of the connectors 40 onto the convex surface 32. Specifically, during actual production and assembly, the connector 40 is connected to the base shell 30 by screws. To facilitate tightening the screws, the screws need to pass through the base shell 30 in the same orientation and be connected to the first connecting post 42. Therefore, when the axial direction of the first connecting post 42 is set at an angle or parallel to the axis of the first mounting hole 43 or the axis of the second mounting hole 44, it can be ensured that the first connecting post 42 is coaxial with the screw, thereby improving the stability of the connection between the connector 40 and the base shell 30.

[0066] In this embodiment, multiple first connecting posts 42 and support posts 47 are provided, and the multiple first connecting posts 42 are spaced apart along the length of the connecting body 41, so that the connecting member 40 is stably connected to the convex surface 32 through the first connecting posts 42. At the same time, the support posts 47 are arranged adjacent to the first connecting posts 42, so that the support posts 47 can abut against the convex surface 32 of the bottom shell 30, thereby supporting the connecting body 41 and improving the structural strength between the connecting body 41 and the bottom shell 30.

[0067] See Figure 4The convex surface 32 can be provided with multiple mounting positions 33 and multiple support positions 35. The multiple mounting positions 33 are set one-to-one with the multiple first connecting columns 42, and the multiple support positions 35 are set one-to-one with the multiple support columns 47.

[0068] In this embodiment, the mounting position 33 can be used to abut against and connect to the first connecting post 42, so that the connector 40 can be connected to the mounting position 33 through the first connecting post 42. Specifically, the mounting position 33 may also have a screw hole for passing a screw through, so that the first connecting post 42 is connected to the mounting position 33 by the screw, ensuring that the connector 40 is securely connected to the convex surface 32.

[0069] Meanwhile, the support position 35 can be used to abut against the support column 47 to support the connector 41 and improve the structural strength of the connector 41, preventing the connector 41 between two adjacent first connecting columns 42 from deforming due to external forces. Specifically, the support position 35 can be configured as a frustum structure to abut against the end of the support column 47 away from the connector 41, thereby supporting the support column 47 and the connector 41 and ensuring the structural strength of the connector 40.

[0070] Figure 9 yes Figure 4 A schematic diagram of the connectors and light board of the LED module.

[0071] See Figure 9 The central axis of the first connecting post 42 on each connector 40 extends in the same direction. That is, the central axis of the first connecting post 42 on different connectors 40 extends in the same direction to facilitate the installation of the connector 40 onto the base shell 30.

[0072] It should be noted that the central axes of the first connecting posts 42 on the same connector 40 are arranged in parallel and face the same direction. Furthermore, among multiple connectors 40, the central axes of the first connecting posts 42 are arranged in parallel and face the same direction. This facilitates the installation of multiple connectors 40 onto the base shell 30.

[0073] In this embodiment, the connector 40 can be made of plastic, so that the lamp panel 50 and the mask 60 are connected to the bottom shell 30 through the connector 40.

[0074] It should be noted that when the connector 40 is made of plastic, a copper post 46 can be provided inside the first connecting post 42. The copper post 46 is used to connect screws to improve the connection stability between the connector 40 and the convex surface 32.

[0075] In some other embodiments, the connector 40 may be made of metal to improve the structural strength of the connector 40, so that the lamp panel 50 and the mask 60 are connected to the bottom shell 30 through the connector 40.

[0076] In addition to screw connection, the fastening method between the first connecting post 42 and the mounting position 33 can also adopt a snap-fit ​​structure, locking structure or connecting bolt structure, so that the first connecting post 42 can be limited on the mounting position 33.

[0077] See Figure 4 The LED module 20 may also include a sealing ring. A sealing step 34 is formed on the periphery of the convex surface 32, and the sealing ring is disposed on the sealing step 34 and seals between the convex surface 32 and the mask 60 and the lamp panel 50.

[0078] In this embodiment, after the lamp board 50 and the mask 60 are connected to the convex surface 32 of the bottom shell 30 by the connector 40, sealant is applied between the periphery of the convex surface 32 and the edges of the lamp board 50 and the mask 60. After the sealant cools, it forms a sealing ring. That is, the sealing ring is set between the sealing step 34 and the edges of the lamp board 50 and the mask 60, so that the sealing ring seals between the periphery of the convex surface 32 and the edges of the lamp board 50 and the mask 60, preventing moisture from entering the LED module 20.

[0079] Figure 10 yes Figure 4 Another partial schematic diagram of the LED module.

[0080] See Figure 4 and Figure 10 The light panel 50 may include a substrate 52, a sealant layer, and a plurality of LED beads 53. The plurality of LED beads 53 are spaced apart on the substrate 52, and the sealant layer is attached to the substrate 52 and to the periphery of the LED beads 53, so that the sealant layer can seal the substrate 52 and the LED beads 53, preventing the substrate 52 and the LED beads 53 from being affected by water leakage.

[0081] It should be noted that the LED bead 53 can be set to RGB three-color LED beads so that the light panel 50 can display different colors or images.

[0082] In addition, the sealant layer is an adhesive layer formed after potting, that is, liquid glue is applied to the substrate 52 and located between two adjacent LED beads 53, and the adhesive layer is formed after the glue solidifies, so as to ensure the sealing between the substrate 52 and the LED beads 53.

[0083] In this embodiment, the mask 60 may be provided with a plurality of limiting holes 61. After the lamp board 50 and the mask 60 are connected to the connector 40 in sequence, the limiting holes 61 on the mask 60 can limit the LED beads 53 and form a protection to prevent external forces from affecting the LED beads 53.

[0084] In summary, the bottom shell 30 has an arc-shaped structure, with its two opposite sides being a concave surface 31 and a convex surface 32. Multiple connectors 40 are provided and connected to the convex surface 32. Both the lamp panel 50 and the face mask 60 are arc-shaped. The lamp panel 50 is connected to the connector 40 and located on the side of the connector 40 facing away from the bottom shell 30. The face mask 60 is connected to the connector 40 and located on the side of the lamp panel 50 facing away from the connector 40. In other words, the lamp panel 50 and the face mask 60 are located on the same side of the connector 40. Meanwhile, the extension direction of the connector 40 is perpendicular to the tangent of the convex surface 32, and the arc-shaped extension directions of the multiple connectors 40 and the bottom shell 30 are arranged at intervals, so that the side of the multiple connectors 40 facing away from the convex surface 32 is also located on the same arc-shaped surface. This facilitates the close contact and stable connection of the lamp panel 50 and the mask 60 to the multiple connectors 40, and keeps the lamp panel 50 and the mask 60 in an arc shape, avoiding the lamp panel 50 and the mask 60 from warping or bulging.

[0085] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
