[0034] Please refer to the accompanying Figure 1 -attached Figure 5 The first aspect of the present embodiment relates to an LED module, which comprises a bottom shell 1 and a lamp panel 2. Among them, the edge of the bottom shell 1 is circumferentially annularly provided with a groove 11, which is used to pour glue, and the edge of the bottom shell 1 is circumferentially provided with a surrounding edge 12, which is vertically provided along the thickness direction of the bottom shell 1, and the surrounding edge 12 is used to block the overflow of glue from the edge of the bottom shell 1; the lamp panel 2 is covered on the bottom shell 1, and the lamp panel 2 is glued with the bottom shell 1 by glue, and the lamp panel 2 is attached to the inner wall of the surrounding edge 12.
[0035] In the present embodiment, the lamp panel 2 is the key component in the LED module, which is responsible for converting electrical energy into light energy and providing lighting effect. The lamp panel 2 is a rectangular plate, and a plurality of LED lamp beads are arrayed on the lamp panel 2. The bottom shell 1 mainly plays the role of supporting, protecting and dissipating heat. Specifically, the bottom shell 1 provides stable support for the entire LED module to prevent it from being damaged by external impact and vibration; the bottom shell 1 is usually made of materials with good heat conduction performance, and is designed with heat dissipation structures such as heat dissipation fins, heat dissipation holes, etc., to effectively reduce the working temperature of the LED module and ensure its stable operation in high temperature environment. The bottom shell 1 is usually made of high-strength, corrosion-resistant materials such as aluminum alloy, etc. These materials not only have good mechanical properties and can withstand external impact and vibration, but also have excellent heat dissipation performance, which helps to reduce the working temperature of the LED module and prolong the service life.
[0036] Specifically, the bottom shell 1 is also a rectangular plate, and the four peripheral edges of the bottom shell 1 are formed with grooves 11. When assembling the LED module, the assembler first pours glue in the inside of the groove 11, and the glue can use caulking glue or RTV glue. When the groove 11 is filled with glue, the lamp panel 2 is covered on the bottom shell 1, and the glue is used to bond the panel surface of the lamp panel 2 and the bottom shell 1.
[0037] Further, the edge of the bottom shell 1 is circumferentially provided with a surrounding edge 12, which is equivalent to a batten structure surrounding the edge of the bottom shell 1, and the height of the surrounding edge 12 is higher than that of the groove 11. The surrounding edge 12 forms a circumferential surrounding structure, and during assembly, the lamp panel 2 is embedded in the inside of the surrounding structure, so as to avoid the overflow of glue from the edge of the bottom shell 1.
[0038] The LED module provided by the embodiment avoids the conventional mode of back full glue pouring, thereby reducing the weight of the whole LED module, effectively reducing material waste, reducing cost, and not needing to pour glue on both the front and back surfaces, reducing the complexity of the glue pouring process and assembly difficulty, and the setting of the surrounding edge 12 further avoids the overflow of glue from the edge of the bottom shell 1.
[0039] Optionally, the edge of the lamp panel 2 is provided with sealing glue along the circumference.
[0040] In the embodiment, the lamp panel 2 is filled with a layer of glue with a thickness of about 0.3 mm on the plate surface close to the edge.
[0041] By setting the sealing glue along the circumference of the edge of the lamp panel 2, the waterproof property can be further enhanced. During use, the product is prone to damage to the surrounding edge 12 due to collision with the periphery of the LED module, and the setting of the sealing glue on the outer periphery of the lamp panel 2 can prevent water from entering the inside of the LED module from the broken surrounding edge 12, thereby avoiding damage to the internal circuit of the LED module.
[0042] Optionally, the inner wall of the surrounding edge 12 is provided with a plurality of reinforcing ribs 121.
[0043] Specifically, the reinforcing rib 121 is in a semi-cylindrical shape, and the reinforcing rib 121 is formed in an integral manner on the inner wall of the surrounding edge 12, and a plurality of reinforcing ribs 121 are provided in the extension direction of the surrounding edge 12.
[0044] In the embodiment, the strength of the surrounding edge 12 is effectively enhanced by the setting of the plurality of reinforcing ribs 121, the damage of the surrounding edge 12 caused by the direct collision of external force with the periphery of the LED module is avoided, and the safety and service life of the LED module are ensured. On the other hand, by setting the reinforcing rib 121, the thickness of the surrounding edge 12 can be appropriately reduced, thereby reducing the weight of the whole LED module to a certain extent.
[0045] Optionally, the edge of the bottom shell 1 is provided with a boss 13 along the circumference, the boss 13 is located on the side of the groove 11 away from the surrounding edge 12, and the boss 13 is vertically arranged along the thickness direction of the bottom shell 1.
[0046] In the embodiment, the boss 13 is annularly arranged on the side of the groove 11 away from the surrounding edge 12, and the lamp panel 2 can be directly covered on the boss 13 after the glue filling in the groove 11 is completed.
[0047] The setting of the boss 13 can support and limit the installation of the lamp panel 2, thereby improving the assembly and ensuring that the lamp panel 2 remains flat after being installed on the bottom shell 1.
[0048] Optionally, the side wall of the boss 13 opposite to the surrounding edge 12 constitutes one side of the inner wall of the groove 11.
[0049] In the embodiment, one side wall of the boss 13 forms one side inner wall of the groove 11, so that the structure of the boss 13 can be reasonably utilized, and the structure in the horizontal direction of the bottom shell 1 tends to be compact. It can be understood that, under the condition that the size of the bottom shell 1 is allowed, the boss 13 can also be separately arranged, that is, a certain gap is formed between the boss 13 and the groove 11.
[0050] Optionally, the cross section of the groove 11 is quadrangular.
[0051] In the embodiment, the cross section of the groove 11 is quadrangular, and in other embodiments, the cross section of the groove 11 can also be irregular or curved.
[0052] Optionally, a plurality of connecting columns 14 are arranged on the bottom shell 1 along the circumference, the connecting columns 14 are provided with a plurality of mounting holes 141, the lamp plate 2 is provided with positioning holes 21 corresponding to the mounting holes 141, and a fastener can pass through the positioning holes 21 and the mounting holes 141 in sequence and be fixed in the mounting holes 141.
[0053] In the embodiment, the fastener can be a rivet or a screw. Exemplarily, a screw is used. The screw first passes through the positioning hole 21 and is directly screwed in the mounting hole 141, so as to further ensure the connection strength of the lamp plate 2 and the bottom shell 1, thereby ensuring the service life. The connecting column 14 and the bottom shell 1 can be an integral structure to reduce the assembly link. A plurality of connecting columns 14 are arranged along the circumference of the bottom shell 1 at intervals, so as to improve the connection strength and stability.
[0054] Further, the connecting column 14 is arranged in the groove 11, and a plurality of connecting columns 14 are arranged at intervals along the extension direction of the groove 11.
[0055] In the embodiment, the connecting column 14 is arranged in the groove 11 along the extension direction of the groove 11. Specifically, the bottom wall of the groove 11 can extend upwards to form a cylindrical structure. In order to ensure the overall connectivity of the groove 11, a certain gap is formed between one side of the connecting column 14 and the inner wall of the groove 11. If it is necessary to increase the gap value, the inner wall of the groove 11 relative to the connecting column 14 can form an arc surface corresponding to the outer wall surface of the connecting column 14, so as to facilitate uniform and continuous pouring of glue along the extension direction of the groove 11.
[0056] The second aspect of the embodiment also relates to an LED display screen integrating a plurality of LED modules.
[0057] The LED display screen configured with the LED module can effectively reduce the weight of the overall LED display screen, thereby saving costs, and can reduce the process difficulty in the assembly of the overall LED display screen and improve the assembly.
