Here, in the present embodiment, the front side of the annular partition 30 refers to a side of the LED display device facing a viewer. When the LED display device is vertically placed, the front side of the annular partition 30 faces forward; when the LED display device is horizontally placed and the LED module 20 faces the ground, the front side of the annular partition 30 refers to the lower surface thereof, and the annular partition 30 is located below the cabinet 10; when the LED display device is horizontally placed and the LED module 20 is oriented toward the sky, the front side of the annular partition 30 refers to the upper surface thereof, and the annular partition 30 is located above the cabinet 10.

It should be noted that, in order to weaken the contact heat transfer effect between the LED module 20 and the box 10, the annular partition 30 is made of a material with a small thermal conductivity, so as to reduce the heat transfer effect therebetween.

And, adopt magnetism to inhale subassembly 40 magnetism and inhale the complex connected mode, have simple structure, the advantage of the installation of being convenient for.

The first magnetic member 41 may be one of a magnet or an iron piece, and the second magnetic member 42 may be the other of a magnet or an iron piece. Alternatively, the first magnetic attracting element 41 and the second magnetic attracting element 42 are both configured as magnets.

In this embodiment, the first magnetic member 41 includes a magnetic iron piece, and the second magnetic member 42 includes a magnet. By adopting the arrangement mode, the device has the advantage of convenience in operation.

Of course, the connection between the annular partition 30 and the box 10 is not limited to the magnetic attraction assembly 40, and other connection methods, such as screw connection, etc., can be used. However, the magnetic assembly 40 is connected in a matching manner, so that the structure is simpler and the operation is easier.

In the present embodiment, the LED module 20 is connected to the annular partition 30 to be connected to the housing 10 through the annular partition 30. By adopting the connection mode, the connection structure can be formed between the LED module 20 and the annular partition plate 30, and compared with the structure that the LED module 20 and the annular partition plate 30 are respectively connected with the box body 10, the LED module and the annular partition plate 30 can be more firmly attached to each other, so that the stability of the heat transfer effect of the annular partition plate 30 is improved.

Specifically, the annular partition 30 and the LED module 20 are bonded and connected by a glue layer. The annular partition plate 30 and the LED module 20 are connected in a sticking mode, and the LED module has the advantages of simple connection structure and convenience in operation. Moreover, the bonding mode improves the connection reliability between the LED module 20 and the annular partition plate 30.

Of course, the annular partition 30 and the LED module 20 are not limited to be connected by adhesive bonding, and other connection methods, such as screw connection, may also be used. However, the mode of adhesive layer bonding connection is adopted, so that the structure is simpler, the operation is easier, and the reliability is higher.

As shown in fig. 1, 3 and 4, the inner ring of the annular partition 30 has a plurality of bearing bosses 31 arranged at intervals along the circumferential direction thereof, and the plurality of first magnetic attracting elements 41 are arranged on the plurality of bearing bosses 31 in a one-to-one correspondence manner. By adopting the bearing boss 31 with the structure, on one hand, the first magnetic suction piece 41 can not occupy the space of the outer ring of the annular partition plate 30, so that the outer ring of the annular partition plate 30 keeps consistent in thickness, the outer ring of the annular partition plate 30 has the same heat conduction efficiency, and the temperature consistency of the outer edge of the LED module is better; on the other hand, the annular partition plate 30 can be ensured to have higher structural strength, and the strength of the annular partition plate 30 cannot be weakened due to the arrangement of the bearing boss 31.

Specifically, since the bearing boss 31 is disposed at the inner ring of the annular partition plate 30, the thickness of the outer ring of the annular partition plate 30 can be made uniform, so that the heat dissipation performance of the outer edge of the LED module 20 can be kept uniform. In the inner ring of the annular partition 30, since the area of the bearing boss 31 is relatively small, the contact area between the bearing boss 31 and the LED module 20 is also relatively small, and the arrangement of the bearing boss 31 also reduces the heat transfer efficiency between the LED module 20 and the first magnetic attraction piece 41.

It should be noted that, in the related art, the first magnetic attraction piece 41 and the second magnetic attraction piece 42 are adopted between the LED module 20 and the box 10 to magnetically attract the matching manner for connection, and since the first magnetic attraction piece 41 and the second magnetic attraction piece 42 are different from the box 10 in material, the difference of heat conduction efficiency can be caused, so that the temperature of the LED module 20 is uneven, and the display effect of the LED display device is affected. And in this embodiment, owing to inhale the piece 41 setting with first magnetism on the boss 31 that bears of annular baffle 30, utilize annular baffle 30 also to weaken LED module 20 and the first heat conduction efficiency of inhaling between the piece 41 of inhaling to reduce the heat that the LED module gived off through magnetism subassembly 40, make the heat that the LED module gived off through magnetism subassembly 40 and LED module directly equal to the heat that the LED module gived off in to the air, LED module 20 temperature everywhere is more even.

Specifically, the LED module 20 and the annular partition 30 are both rectangular structures, and the bearing boss 31 is disposed at an inner ring of the rectangular structure. The annular partition 30 has a rectangular structure and can be adapted to the shape of the LED module 20, so that the annular partition 30 can better reduce the heat conduction efficiency between the outer edge of the LED module 20 and the box 10.

In this embodiment, the outer circumference of the annular partition 30 is equal to the outer circumference of the LED module 20, so that the outer edges of the LED module 20 can be cooled by the annular partition 30, and have the same cooling efficiency.

In particular, the bearing bosses 31 are uniformly arranged on the long and short sides of the rectangular structure, respectively. On the short side of the rectangular structure, the annular partition 30 is provided with 3 bearing bosses 31, wherein 2 bearing bosses 31 are arranged at the corners of the rectangular structure, and the other 1 bearing bosses are arranged at the middle points of the short side. On the long side of the rectangular structure, the annular partition 30 is provided with 4 bearing bosses 31, and the 4 bearing bosses 31 are respectively arranged at 4 equal division points of the long side. At 4 corners of the rectangular structure, the bearing bosses 31 on the long side coincide with the bearing bosses 31 on the short side.

In this embodiment, the annular partition 30 has a plurality of mounting holes spaced along the circumference thereof, and the first magnetic attraction pieces 41 are disposed in the mounting holes in an interference manner. By adopting the installation form, the device has the advantages of simple structure and convenient operation.

In this embodiment, the mounting hole is disposed on the bearing boss 31, a portion of the first magnetic member 41 is disposed in the mounting hole in an interference manner, and another portion of the first magnetic member 41 protrudes from the mounting hole, so that the thickness of the inner ring of the annular partition plate 30 can be kept consistent.

In other embodiments, the mounting holes may be located directly on the outer circumference of the annular partition 30. However, with this arrangement, on the one hand, since the width dimension of the annular partition 30 is consistent with the outer edge dimension of the LED module 20, the outer edge dimension of the LED module 20 is smaller, and the width dimension of the annular partition 30 is also smaller. This can reduce the area of the first magnetic part 41 or adopt the first magnetic part 41 with a larger length, and therefore, either the magnetic attraction between the first magnetic part 41 and the second magnetic part 42 can be reduced, or the arrangement of the first magnetic part 41 and the second magnetic part 42 can be unfavorable. On the other hand, since the first magnetic attraction member 41 is directly disposed on the outer ring of the annular partition plate 30, the thickness of the annular partition plate 30 is increased, which is not favorable for heat dissipation of the outer edge of the LED module 20.

In this embodiment, annular partition plate 30 is made by the plastic material, adopts the plastic material, can make annular partition plate 30 have suitable structural strength on the one hand in order to support first magnetism to inhale piece 41, and on the other hand can make the less characteristic of coefficient of heat conductivity that utilizes the plastic material, reduces LED module 20's radiating efficiency.

In this embodiment, the annular partition 30 may be made of an existing plastic material available on the market, and is preferably made of PC plastic (Polycarbonate).

In particular, the annular partition 30 has a thickness comprised between 2mm and 3 mm. With the size range, the annular partition 30 has a proper heat transfer rate, so that the LED module 20 has a proper heat dissipation efficiency, and the outer edge of the LED module 20 and the portion thereof directly contacting with air have the same heat dissipation rate, thereby achieving the effect of uniform heat dissipation of the LED module 20.

Wherein, the thickness of the annular partition plate 30 can be any value between 2mm, 2.2mm, 2.4mm, 2.5mm, 2.6mm, 2.8mm, 3mm and 2mm to 3 mm. In the present embodiment, the thickness of the annular partition 30 is 2.5mm.

The LED display device with the structure can utilize the plurality of LED modules 20 to enhance the display area of the LED display device so as to enhance the display effect of the LED display device and further meet various requirements.

In this embodiment, the edge ribs 11, i.e., the frame of the casing 10, form the outer edges of the casing 10.

Specifically, because box 10 is provided with edge 11 and brace rod 12, and then every annular baffle 30 homoenergetic is laminated with corresponding edge 11 and brace rod 12 mutually to make every LED module 20's outer border all dispel the heat through annular baffle 30, so that every LED module 20's outer border and the part that directly contacts with the air have the same radiating rate, reached a plurality of LED modules 20 all have the same radiating rate, in order to reach the even effect of heat dissipation.

It should be noted that, in order to make the LED display device have a larger display area, can set up a plurality of brace rods 12 along the width direction of box 10, above-mentioned a plurality of brace rods 12 all extend to boundary rod 11, brace rod 12 that sets up along the length direction of box 10 and the crisscross setting of brace rod 12 that sets up along the width direction of box 10, and separate into the assembly unit of a plurality of installation LED modules 20 with box 10 through brace rod 12 and boundary rod 11, a plurality of assembly units and a plurality of LED modules 20 one-to-one, every assembly unit all is provided with annular baffle 30, with dispel the heat to the outer border of the LED module 20 that corresponds.
