[0030] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 1 The orientation is referenced.

[0031] Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Instead, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0032] like Figures 1 to 3 As shown, the present invention provides an LED display module, which includes a base plate 1, a PCB light board 2, and a mask 3 stacked in sequence, wherein the edges of the base plate 1 are each provided with ridges, which surround the edges of the PCB light board 2. The mask 3 is provided with a plurality of first through holes in an array, and the PCB light board 2 is provided with a plurality of lamp beads 21 in an array, and the plurality of lamp beads 21 are arranged in a one-to-one correspondence with the plurality of first through holes. Specifically, after the lamp beads 21 pass through the first through holes, the ends of the lamp beads 21 extend out of the first through holes. The base plate 1 is provided with a plurality of heat-conducting components 4 in an array, and the PCB light board 2 and the mask 3 are both snap-fitted to the heat-conducting components 4. The PCB light board 2 and the mask 3 are directly snap-fitted to the base plate 1 without the need for screw fixation, making assembly and disassembly convenient. The heat-conducting components 4 used for snapping the PCB light board 2 and the mask 3 have a heat-conducting function, transferring heat to the base plate 1 for heat dissipation. The plurality of heat-conducting components 4 arranged in an array effectively improve the heat conduction efficiency, preventing the LED display module from generating high temperatures that damage the PCB light board 2.

[0033] like Figure 4As shown, the thermal assembly 4 includes a thermal block 41 and a thermal base 42. The thermal block 41 is preferably a rectangular parallelepiped and is mounted on the thermal base 42. The thermal base 42 is mounted on the bottom plate 1. The PCB light board 2 and the face mask 3 are both engaged with the thermal block 41. Furthermore, the thermal block 41 is provided with a first slot 411 and a second slot 412. The PCB light board 2 is provided with a second through hole 22 that matches the shape of the thermal block 41. The face mask 3 is provided with a third through hole 33 that matches the shape of the thermal block 41. Neither the second through hole 22 nor the third through hole 33 overlaps with the first through hole. The cross-sectional areas of the second through hole 22 and the third through hole 33 are slightly smaller than those of the thermal block 41. When installing the PCB light board 2 and the face shield 3, first install the PCB light board 2, then the face shield 3. Slightly deforming the heat conducting block 41 allows it to pass through the second through hole 22 and the third through hole 33. After the PCB light board 2 and the face shield 3 are installed, the heat conducting block 41 fits within the second through hole 22 and the third through hole 33. The first engaging slot 411 engages with the second through hole 22, and the second engaging slot 412 engages with the third through hole 33, ensuring that the PCB light board 2 and the face shield 3 are stably mounted on the base plate 1. Furthermore, the heat conducting block 41 acts as the heat dissipation fin of the PCB light board 2, improving heat dissipation efficiency and preventing high temperatures from the LED display module from damaging the PCB light board 2.

[0034] Preferably, the openings of the first slots 411 and second slots 412 on the same thermal block 41 face each other, and the notches of the first slots 411 on at least two rows of thermally conductive components 4 face each other, while the notches of the second slots 412 on at least two rows of thermally conductive components 4 face each other. This enhances the stability of the installation of the PCB light board 2 and the mask 3. The base plate 1, thermally conductive block 41, and thermally conductive base 42 are integrally formed from aluminum, making them easy to process and durable. This integrated structure further improves thermal conductivity.

[0035] like Figure 3 As shown, when the LED display module is placed horizontally, the top surface of the heat conducting block 41 is higher than the top surface of the lamp beads 21. When a heavy object presses against the upper surface of the LED display module, the object only contacts the top surface of the heat conducting block 41, transferring the pressure to the base plate 1 through the heat conducting block 41, thus preventing damage to the lamp beads 21.

[0036] like Figure 4 As shown, a plurality of heat-conducting protrusions 413 are provided on the top surface of the heat-conducting block 41 to increase the contact area between the air and the heat-conducting block 41 and improve the heat exchange efficiency.

[0037] As shown in the figure, the cross-section of the first through hole is square, which is used to match the shape of the lamp bead 21.
