[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1-Figure 6 , a heat dissipation device of a high-power large-scale LED lamp group shown in the figure includes a metal plate 1 that fits with the bottom of the lamp group; it also includes a plurality of heat sinks 2 fixed to the bottom of the metal plate 1, a support shaft 3 is fixed to the outside of the plurality of heat sinks 2, a bracket plate 4 is fixed to the outside of the support shaft 3, and a driving member 5 for driving the support shaft 3 to rotate is installed on the outside of the bracket plate 4; and two frame plates 6 installed on both sides of the plurality of heat sinks 2, and heat dissipation fans 7 are arranged in the two frame plates 6. The two heat dissipation fans 7 discharge the hot air in the gaps between the plurality of heat sinks 2, and a rotating rod 8 that is rotatably connected to the frame plate 6 is fixed to the outside of the heat dissipation fan 7, and an adjustment unit 9 is installed on the rotating rod 8 at the outer ends of the two frame plates 6, and a track opening 10 is opened on the inner wall of both sides of the bracket plate 4, and the adjustment unit 9 moves along the track opening 10 to change the direction of the heat dissipation fan 7 in the frame plate 6; and a dust removal unit 11 installed on the outside of one of the frame plates 6, the heat dissipation fan 7 in the frame plate 6 is used to blow air toward the heat sink 2, and the heat dissipation fan 7 in the other frame plate 6 is used to suck air toward the heat sink 2.

[0035] In this solution, the cooling fans 7 designed in the two frame plates 6 on the outside of the heat sink 2 are used to suck and blow, so as to realize the extraction of residual hot air in the gaps between the multiple heat sinks 2, so that the heat dissipation device can achieve better heat dissipation effect. During the heat dissipation process, the dust removal unit 11 can be used to filter the gas entering the heat sink 2 to isolate the dust.

[0036] Unlike the traditional heat sink 2, the heat sink 2 of this solution has two parallel beveled edges on its cross-sectional shape, and the two frame plates 6 are respectively attached to the two beveled edges. According to the principle that hot air flows upward, this solution installs the two frame plates 6 at a certain tilt angle, so that the exhausted hot air is easier to be discharged upward, and when inhaling, it is also easier to inhale the cold air at a low position.

[0037] For further information, see Figure 4 , Figure 5 as well as Figure 8 The adjustment unit 9 includes a connecting plate 12 fixed to the outer end of the rotating rod 8, and an adjusting protrusion 13 adapted to the track opening 10 is fixed to the outer end of the connecting plate 12. A magnetic strip 14 attracted to the outer end of the frame of the cooling fan 7 is fixed in the frame plate 6. When the frame plate 6 rotates with the support shaft 3, the adjusting protrusion 13 slides in the track opening 10 and drives the rotating rod 8 and the cooling fan 7 to rotate accordingly;

[0038] In order to make it easier for the adjusting protrusion 13 to enter the rail opening 10 , a chamfer is provided on the outer side of the rail opening 10 to facilitate the entry of the adjusting protrusion 13 .

[0039] The principle of the adjustment unit 9 adjusting the angle of the cooling fan 7 is as follows: the driving member 5 drives the support shaft 3 and the heat sink 2 to rotate, so that the frame plate 6 and the cooling fan 7 rotate accordingly. During the rotation process, the adjustment protrusion 13 can enter the track opening 10. As the stage light rotates, the adjustment protrusion 13 will be driven to move along the track opening 10. During the movement process, the cooling fan 7 Figure 4-Figure 6 as well as Figure 8 As shown, it can be rotated accordingly. After the adjusting protrusion 13 is separated from the track opening 10, the cooling fan 7 is reset by the action of the magnetic strip 14.

[0040] For further information, see Figure 1 and Figure 2 , the driving member 5 includes a driving motor 15 fixed to one side of the bracket plate 4 through a motor frame, and the output end of the driving motor 15 is fixed to the outer end of the support shaft 3 through a coupling;

[0041] The designed driving motor 15 rotates, so that the supporting shaft 3 rotates accordingly, thereby driving the stage light to rotate.

[0042] For further information, see Figure 1 , Figure 7 as well as Fig. 9 and Fig.11 The dust removal unit 11 includes a dust removal net frame 16, both ends of the dust removal net frame 16 are fixed with docking blocks 17, the docking blocks 17 are fixed with plug posts 18, the frame plate 6 is fixed with a docking plate 19 adapted to the plug posts 18, a cleaning component 20 is installed in the frame plate 6, and the residual dust in the dust removal net frame 16 is cleaned by the cleaning component 20;

[0043] Among them, the cleaning component 20 includes a cleaning frame 21 located in the frame plate 6, a main rod 22 plugged into the frame plate 6 is fixed on one side of the cleaning frame 21, and two sliding rods 23 plugged into the frame plate 6 are fixed on the other end, a docking rod 24 is fixed to the outer end of the main rod 22, and an extrusion spring 25 that abuts against the docking rod 24 and the outer side of the frame plate 6 is sleeved on the outer side of the main rod 22, a corrugated plate 26 adapted to the docking rod 24 is fixed to the inner side of the bracket plate 4, and a plurality of brush plates 27 are fixed at equal intervals in the cleaning frame 21.

[0044] The principle of filtering and screening the gas entering the heat sink 2 by the dust removal unit 11 is as follows: first, the gas enters between the multiple heat sinks 2 through the rotation of the cooling fan 7, and the dust in the gas can be isolated when the gas passes through the dust removal mesh frame 16. Subsequently, the main rod 22 in the frame plate 6 rotates along with the rotation through the rotation of the stage light. When the main rod 22 contacts the corrugated plate 26, the extrusion spring 25 is used to squeeze the docking rod 24 and the corrugated plate 26 to form a corresponding telescopic adjustment, which drives the corresponding telescopic movement of the cleaning frame 21, so that the brush plate 27 can contact and wipe the dust removal mesh frame 16 to remove the residual dust thereon.

[0045] It should be noted that the brush plate 27 is tilted, and part of the brushes are plugged into the holes of the dust removal frame 16, so that during the pumping process, the brush plate 27 can clean and remove the dust remaining on the dust removal frame 16 due to the plugging into the holes.

[0046] In this solution, when the stage light rotates, the cooling fan 7 rotates accordingly, and the adjustment protrusion 13 on the cooling fan 7 contacts the track opening 10. Then, when the adjustment protrusion 13 moves along the track opening 10, the cooling fan 7 will adjust its angle accordingly. Figure 6 As shown, no matter the cooling fan 7 is in the blowing or inhaling state, the range can be controlled so that the blowing and inhaling ranges are negotiated to avoid the secondary inhalation of the exhausted hot air.

[0047] In this solution, a heat dissipation method for a high-power large-scale LED lamp group includes the following steps:

[0048] S1. Through the rotation of two cooling fans 7, a blowing and a suction are realized to discharge the hot air flow in the heat sink 2;

[0049] S2. When the stage light rotates, the adjustment unit 9 contacts the track opening 10 to adjust the angle of the cooling fan 7 so that the gas blown out by the blowing fan can be away from the suction fan.

[0050] S3. When the stage light rotates, the cleaning component 20 in the dust removal unit 11 can be triggered to remove the residual dust and increase the air intake.

[0051] Example 2: Please refer to Figure 9-11 This embodiment further explains the first embodiment, and the difference lies in that the installation method of the dust removal screen frame 16 is optimized to facilitate personnel to disassemble and replace the dust removal screen frame 16.

[0052] Specifically, mutually magnetically attracted magnetic blocks are installed on the adjacent surfaces of the docking plate 19 and the docking block 17. The designed magnetic blocks are used to make the docking plate 19 and the docking block 17 fit together magnetically. When disassembling, personnel can directly remove them by force.

[0053] Example 3: Please refer to Figure 1 and Figure 3 This embodiment further illustrates other embodiments, and the difference lies in the determination of the blowing and suction positions of the two cooling fans 7.

[0054] Specifically, the cooling fan 7 for blowing air into the heat sink 2 is installed at the lower oblique edge of the plurality of heat sinks 2 , and the cooling fan 7 for sucking air into the heat sink 2 is installed at the upper oblique plate of the heat sink 2 .

[0055] In this solution, when the stage light is installed on the floor, the stage light is facing upwards. Figure 1 As shown, the stage light and the bracket plate 4 are in a horizontal state, at which time the dust removal unit 11 is docked with the frame plate 6 away from the stage light, and the frame plate 6 is used to inhale external air;

[0056] When the stage light is installed on the ceiling, at this time, the stage light faces downward, the stage light and the bracket plate 4 are in a horizontal state, the dust removal unit 11 is connected to the frame plate 6 close to the stage light, and the frame plate 6 is used for air intake. According to the principle that hot air will naturally move upward, the height of the air intake frame plate 6 is lower than the exhaust frame plate 6 during installation of the equipment, which is convenient for hot air to escape upward and heat dissipation.

[0057] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
