Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0035] LED displays are commonly found on the exterior walls or glass curtain walls of buildings, landmark structures, and large advertising screens. An LED display typically consists of LED modules and a housing. The LED modules are assembled onto the housing to form the LED display for easy modular use. In related technologies, the assembly process of LED modules mainly uses bolts, screws, and other fasteners to secure the LED panel to the base shell. However, when the required resolution of the LED display is high, the spacing between the LEDs on the LED panel will decrease. In this case, it is impossible to use fasteners for assembly, and it is also impossible to perform potting and sealing treatment on the LED panel.

[0036] Based on the above considerations, in order to solve the assembly and sealing problems of the light panel and the base shell in specific scenarios, an LED module was designed. This LED module can bond and fix the light panel to the support node and the first support surface of the base shell through a first adhesive. An avoidance groove is opened on the first support surface to allow the first adhesive to release pressure, which can effectively reduce the probability of the light panel lifting when it is bonded to the first support surface by the first adhesive. At the same time, a first filling groove is also opened on the first support surface, and a second adhesive is filled in the first filling groove. When the light panel is bonded to the front end face of the base shell, the second adhesive can seal the gap between the light panel and the first support surface, which can effectively improve the waterproof performance of the inner side of the light panel.

[0037] The LED module provided in this application will be described in detail below.

[0038] Please refer to Figures 1 to 6 In a first aspect, embodiments of this application provide an LED module 1000, including a lamp panel 100 and a base shell 200. The base shell 200 has a front end face 201 and a rear end face 202. The base shell 200 includes an outer frame structure 210 and a plurality of support beams 220 intersecting inside the outer frame structure 210, with at least two support beams 220 intersecting to form a support node 221. The outer frame structure 210 has a first support surface 211 located on one side of the front end face 201. The lamp panel 100... The first adhesive (not shown in the figure) is connected to the support node 221 and the first support surface 211. The first support surface 211 has a clearance hole 211a, and the first adhesive is applied to the clearance hole 211a. The first support surface 211 also has a first filling groove 211b, which is arranged around the first support surface 211. The first filling groove 211b is filled with a second adhesive (not shown in the figure). The lamp panel 100 is covered by the first filling groove 211b.

[0039] A light board 100 is an electronic component used for lighting. It typically consists of LED beads, a circuit board, a driver circuit, and a heat dissipation device. The circuit board and driver circuit control the light emission of the LED beads to achieve functions such as lighting or display.

[0040] The base shell 200 refers to the main structure used to support the light panel 100. The base shell 200 has a front surface 201 and a rear surface 202; it should be understood that the front surface 201 and the rear surface 202 refer to the two opposite surface structures of the base shell 200. The front surface 201 is used to connect the light panel 100 so that the light panel 100 emits light towards the front surface 201; the rear surface 202 is the back side of the LED module 1000 and is used for connection and fixing.

[0041] The base shell 200 includes an outer frame structure 210 and support beams 220. The outer frame structure 210 refers to a hollow frame structure, which may be, but is not limited to, a rectangular frame, a circular frame, a triangular frame, an arc-shaped frame, or an irregularly shaped frame. The support beams 220 are reinforcement structures located within the hollow outer frame structure 210 and used to connect the outer frame structure 210 to achieve structural strengthening.

[0042] The number of support beams 220 is at least two, for example, there can be any number of two, three or more. The multiple support beams 220 are distributed in a crisscross pattern inside the outer frame structure 210, that is, the multiple support beams 220 can be distributed in different directions, so that the multiple support beams 220 can intersect to form support nodes 221.

[0043] For example, in some embodiments, the outer frame structure 210 may be a rectangular frame, at least one of the multiple support beams 220 may be arranged in any direction, and the other support beams 220 may be arranged perpendicular to the above direction; thus, the support beams 220 arranged in different directions are arranged vertically and form support nodes 221 for the lamp panel 100 to be fixed by the first adhesive.

[0044] The outer frame structure 210 has a first support surface 211 located on one side of the front end face 201. Understandably, the first support surface 211 refers to the wall surface of the outer frame structure 210 facing the front end face 201. Exemplarily, in some embodiments, when the outer frame structure 210 is a rectangular frame, the first support surface 211 is the rectangular ring-shaped wall surface of that rectangular frame facing the front end face 201.

[0045] The lamp panel 100 is connected to the support node 221 and the first support surface 211 by the first adhesive; thus, the middle part of the lamp panel 100 can be fixed by being connected to the support node 221 by the first adhesive, and at the same time, the outer edge of the lamp panel 100 can be connected to the first support surface 211 by the first adhesive, so as to achieve a stable assembly of the lamp panel 100 and the bottom shell 200.

[0046] An avoidance hole 211a is provided on the first support surface 211; wherein, the avoidance hole 211a can be a blind hole structure; the number of avoidance holes 211a can be multiple, and multiple avoidance holes 211a can be arranged sequentially at intervals on the first support surface 211 to form a ring.

[0047] The first adhesive is applied to the clearance hole 211a, and the first adhesive is used to bond and fix the lamp panel 100 and the first support surface 211. In this way, the first adhesive can overflow into the clearance hole 211a to release the pressure of the first adhesive, which can effectively reduce the probability of the lamp panel 100 lifting due to expansion of the first adhesive.

[0048] The first colloid can be an adhesive layer made of various adhesive materials, such as structural adhesive, 3M adhesive, etc.

[0049] A first adhesive filling groove 211b is also provided on the first support surface 211, and the first adhesive filling groove 211b is arranged around the first support surface 211. The first adhesive filling groove 211b is used to fill the second adhesive, and the first adhesive filling groove 211b can be sealed when the lamp board 100 is assembled on the bottom shell 200; in this way, the second adhesive filled in the first adhesive filling groove 211b can form a seal filling between the first support surface 211 and the lamp board 100, so as to achieve the effect of waterproofing the inside of the lamp board 100.

[0050] The second colloid can be a sealant made of various adhesive materials, such as epoxy resin adhesive.

[0051] The LED module 1000 provided in this application embodiment can bond and fix the lamp board 100 to the support node 221 and the first support surface 211 of the bottom shell 200 through a first adhesive. An avoidance groove is provided on the first support surface 211 to allow the first adhesive to release pressure, which can effectively reduce the probability of the lamp board 100 lifting when it is bonded to the first support surface 211 by the first adhesive. At the same time, a first filling groove 211b is also provided on the first support surface 211, and a second adhesive is filled in the first filling groove 211b. When the lamp board 100 is bonded to the front end face 201 of the bottom shell 200, the second adhesive can seal the gap between the lamp board 100 and the first support surface 211, which can effectively improve the waterproof performance of the inside of the lamp board 100.

[0052] Please refer to Figures 1 to 6 In some embodiments, the LED module 1000 further includes a cover plate 300, and the outer frame structure 210 has a second support surface 212 located on one side of the rear end face 202. The cover plate 300 is bonded to the second support surface 212. A second glue filling groove 212a is provided on the second support surface 212, and the second glue filling groove 212a is filled with a second glue. The cover plate 300 covers the second glue filling groove 212a.

[0053] The cover plate 300 refers to the protective structure used to cover the rear end face 202 of the bottom shell 200. The bottom shell 200 is covered by the cover plate 300 to improve the sealing performance of the inner side of the lamp panel 100.

[0054] Optionally, the cover plate 300 may be, but is not limited to, a rectangular plate, a circular plate, a triangular plate, an arc-shaped plate, or other plate structures. In some embodiments, the cover plate 300 has the same configuration as the rear end face 202 of the bottom shell 200, so that the cover plate 300 can fit more closely on the rear end face 202 of the bottom shell 200.

[0055] In some embodiments, the cover plate 300 has a connection port for wiring connections. A waterproof rubber ring is provided at the port of the connection port to improve the waterproof performance of the cover plate 300 at the connection port.

[0056] The second support surface 212 refers to the wall surface of the outer frame structure 210 facing the rear end face 202. For example, in some embodiments, when the outer frame structure 210 is a rectangular frame, the second support surface 212 is the rectangular ring-shaped wall surface of the rectangular frame facing the rear end face 202.

[0057] A second adhesive filling groove 212a is provided on the second support surface 212. Optionally, the second adhesive filling groove 212a can be arranged around the second support surface 212. The second adhesive filling groove 212a is used to fill a second adhesive, and the cover plate 300 can seal the second adhesive filling groove 212a when it is assembled with the bottom shell 200. In this way, the second adhesive filling groove 212a can form a seal between the second support surface 212 and the cover plate 300, thereby further improving the sealing and waterproof performance of the cover plate 300.

[0058] Please refer to Figures 1 to 6 In some embodiments, the bottom shell 200 further includes a load-bearing structure 230 disposed inside the outer frame structure 210, the load-bearing structure 230 being connected to the outer frame structure 210 and / or the support beam 220; the load-bearing structure 230 abuts against the lamp panel 100.

[0059] The load-bearing structure 230 refers to the structure used to support the lamp panel 100. Optionally, the load-bearing structure 230 may be, but is not limited to, a support block, a support plate, a support bracket, etc.; the number of load-bearing structures 230 may be one or more.

[0060] The load-bearing structure 230 can be connected to the outer frame structure 210, for example, it can be integrally formed with the outer frame structure 210.

[0061] Alternatively, the load-bearing structure 230 can be connected to the support beam 220, for example, it can be integrally formed with the support beam 220.

[0062] Alternatively, load-bearing structures 230 may be provided on both the outer frame structure 210 and the support beam 220.

[0063] For example, in some embodiments, the load-bearing structure 230 can be a cylindrical support structure, and the two opposite ends of the cylindrical support structure along the axial direction abut against the lamp panel 100 and the bottom shell 200 respectively; in this way, the load-bearing structure 230 can provide support for the lamp panel 100 to improve the load-bearing capacity of the lamp panel 100.

[0064] Please refer to Figures 1 to 6 In some embodiments, the support structure 230 is bonded to the lamp panel 100.

[0065] In this embodiment, the supporting structure 230 is bonded and fixed to the lamp panel 100. In this way, the supporting structure 230 can support the lamp panel 100 and also form a connection and reinforcement with the lamp panel 100, which can further improve the stability of the lamp panel 100.

[0066] Please refer to Figures 1 to 6 In some embodiments, at least two support beams 220 are intersected and form multiple hollow regions 222, and each hollow region 222 is provided with a load-bearing structure 230.

[0067] It should be understood that when multiple support beams 220 are distributed intersectingly inside the outer frame structure 210, the intersecting support beams 220, or the intersecting support beams 220 and the outer frame structure 210, can enclose and form a hollow area 222.

[0068] In this embodiment, the load-bearing structure 230 can be set in the hollow region 222. In this way, the load-bearing structure 230 can be used to support and reinforce the lamp panel 100 in the hollow region 222, thereby effectively improving the load-bearing capacity and stability of the lamp panel 100 in the hollow region 222.

[0069] Please refer to Figures 1 to 6 In some embodiments, the bottom shell 200 also includes a plurality of reinforcing rods 240, and at least one reinforcing rod 240 is disposed in a hollow region 222; the reinforcing rod 240 is connected to the support beam 220 and / or the outer frame structure 210.

[0070] Understandably, the reinforcing rod 240 refers to a reinforcing structure installed in the hollow region 222 to provide structural reinforcement for the support beam 220 and / or the outer frame structure 210. The reinforcing rod 240 has a rod-like structure, and its opposite ends can be connected to the support beam 220 or the outer frame structure 210.

[0071] This configuration allows for further enhancement of the connection strength between the support beam 220 and / or the outer frame structure 210 using the reinforcing rod 240, thereby improving the overall structural strength of the bottom shell 200.

[0072] Please refer to Figures 1 to 6 In some embodiments, there are multiple reinforcing rods 240, which are distributed in a cross pattern; a load-bearing structure 230 is provided at the intersection of at least two reinforcing ribs.

[0073] In this embodiment, multiple reinforcing rods 240 can be distributed in a cross pattern to further enhance the connection strength of the support beam 220 and / or the outer frame structure 210.

[0074] Meanwhile, a load-bearing structure 230 is provided at the intersection of at least two reinforcing ribs; thus, the load-bearing structure 230 can be provided at any point in the hollow region 222 to improve the support effect on the lamp panel 100.

[0075] Please refer to Figures 1 to 6 In some embodiments, the bottom shell 200 further includes a magnetic structure 250, which is disposed on the outer frame structure 210 and faces the rear end face 202.

[0076] The magnetic structure 250 can be a magnetic structure such as a strong magnet. The magnetic structure 250 is disposed on the outer frame structure 210 and faces the rear end face 202; thus, the magnetic structure 250 can be used to attach to other structures to achieve assembly.

[0077] Optionally, the number of magnetic structures 250 can be one or more; multiple magnetic structures 250 can be arranged around the outer frame structure 210 to achieve stability when the magnetic structures 250 are attached and installed.
