For example, the second circulation cavity is communicated with the first circulation cavity, so that a relatively abundant cavity is formed, heat generated by the second LED lamp is convenient to collect, and the heat dissipation efficiency is improved.

For example, the second cylinder has an outer diameter equal to the inner diameter of the first cylinder. For example, the second cylinder is coaxially connected to the first cylinder. For example, the first cylinder and the second cylinder are integrally molded. For example, the first cylinder is a hollow cylinder with two open sides.

For example, the radiating seat is used for installing a first LED lamp, the first LED lamp comprises a first circuit board and a first LED lamp bead, for example, the first circuit board is annular, for example, the first circuit board can adopt a flexible circuit board, and heat generated by the first LED lamp bead during working can be conducted to the radiating seat.

The flower-shaped heat dissipation body is arranged on the circular heat dissipation surface and connected with the heat dissipation installation ring body, and the flower-shaped heat dissipation body is used for dissipating heat generated by the first LED lamp beads during working and conducted to the heat dissipation seat to the outside. For example, the flower-shaped heat sink includes a plurality of heat conducting members, and the plurality of heat conducting members are annularly and uniformly disposed on the circular heat dissipating surface, for example, in one embodiment, the plurality of heat conducting members are annularly and uniformly disposed on the circular heat dissipating surface, so that the heat dissipating area can be increased and the heat dissipating efficiency can be improved through the plurality of uniformly disposed heat conducting members, and on the other hand, the structure can be more compact, the actual requirements of mold opening production can be met, and the flower-shaped heat sink is more attractive.

Further, in one embodiment, the heat conducting block is welded with the heat dissipation mounting ring body. Further, in one embodiment, the heat conducting block is integrally formed with the heat dissipating mounting ring.

For example, in one embodiment, the heat sink is disposed obliquely to the circular heat dissipating surface. For example, in one embodiment, the heat sink has an arcuate heat-dissipating surface. For example, in one embodiment, the heat conducting block and the heat sink are integrally formed, which can improve the overall structural strength.

The connecting part is connected with the heat conducting block, the heat radiating part is connected with the connecting part, and the width of the heat radiating part is increased towards the direction far away from the connecting part, for example, the width of the heat radiating part is gradually increased towards the direction far away from the connecting part; in another example, the width of the heat dissipation portion increases stepwise in a direction away from the connection portion. For example, the heat dissipation portion has a side face inclined downward. The tip portion is connected with the radiating portion, two corner ends are formed on two sides of the tip portion connected with the radiating portion, and the radiating distance formed between the two corner ends is 2 times of the width of the middle area of the radiating portion. The width of the tip part is reduced towards the direction far away from the heat dissipation part and forms a tip, for example, the width of the tip part is reduced towards the direction far away from the heat dissipation part and forms a tip at the tail end, so that the two corner ends can form a wider middle part, the tail end of the tip part is in a tip shape, a petal-shaped structure is integrally formed, meanwhile, the wider middle part also has a larger area to be contacted with air, and the heat dissipation efficiency is better. Preferably, the heat conduction block and the radiating fin are made of aluminum profile materials, and further, the heat conduction block and the radiating fin can be integrally formed in a mode of die sinking processing. Therefore, the structural strength of the heat conducting piece can be ensured, and the production is convenient to implement.

Furthermore, the radiating fin is provided with a plurality of air outlet holes on the surface of the tip part, and each air outlet hole is communicated with the hollow inside of the radiating fin, so that the air outlet holes and the radiating holes correspond to each other, the air flow speed of the hollow inside of the heat conducting block and the air flow speed of the hollow inside of the radiating fin are greatly improved, and the radiating efficiency is further improved. For example, the plurality of outlet holes are arranged in a row. In this embodiment, the number of the air outlets is 4, and each of the heat dissipation fins has 4 air outlets arranged in a row on the surface of the tip portion thereof. For example, the air outlet is provided adjacent the distal end of the tip portion, which allows more air in the hollow interior of the heat conducting block and the hollow interior of the heat sink to flow over a wider area, resulting in a higher heat dissipation efficiency.

For improving display brightness, for example, the fin is provided with the phosphor strip, the phosphor strip sets up in the side of fin, the surface of phosphor strip is provided with the fluorescent layer, the base colour of fluorescent layer can set up to the colour of warm look system such as red, yellow, tangerine, so will make the phosphor strip luminous when first LED lamp pearl during operation, because the phosphor strip is located the side of fin, so can make whole flower type radiator have the light of following the side transmission of fin to the luminous luminance of whole flower type radiator has been improved.

Furthermore, a plurality of auxiliary heat dissipation through holes are annularly distributed adjacent to the heat dissipation mounting ring body, so that the air outlet direction of the auxiliary heat dissipation through holes is adjacent to the first LED lamp beads, and the heat dissipation effect is better realized. In this embodiment, the height of the mounting post is greater than the height of the heat dissipation mounting ring body, so that the mounting post protrudes from the upper surface of the heat dissipation mounting ring body, so that the auxiliary plate is located above the heat dissipation mounting ring body, further, in order to enable the air flowing out of the auxiliary heat dissipation through holes to drive the air above the first LED lamp beads to flow sufficiently, for example, the outer diameter of the auxiliary plate is greater than the inner diameter of the heat dissipation mounting ring body, for example, the outer diameter of the auxiliary plate is 110% of the inner diameter of the heat dissipation mounting ring body, so that the auxiliary plate partially covers the heat dissipation mounting ring body and completely covers all the auxiliary heat dissipation through holes, so that the air flowing is adjacent to the heat dissipation mounting ring body to increase the air flow rate above the heat dissipation mounting ring body, so that the micro-motor drives the fan blades to rotate when working, so that the air in the, outside air can follow the louvre and get into, flow by supplementary heat dissipation through-hole again, perhaps also can follow supplementary heat dissipation through-hole and get into again and flow by the louvre, the flow of air can be confirmed according to the direction of rotation of flabellum, but no matter how the flabellum rotates, the homoenergetic drives the air flow of heat dissipation installation ring body top, thereby take away the produced heat of first LED lamp pearl during operation that will install on the heat dissipation installation ring body, owing to adopt the mode that external force interferes, and then the radiating efficiency of the heat dissipation installation ring body has been improved, the life of first LED lamp pearl has been improved effectively.

It should be noted that the structure of the heat dissipation block is the same as that of the heat dissipation fin, and the difference is that the overall structural size of the heat dissipation block is smaller than that of the heat dissipation fin, and the heat dissipation block can also be understood as a scaled-down version of the heat dissipation fin. For example, the heat dissipation block includes a first connection portion, a second heat dissipation portion, and a second tip portion, and the entire widths of the first connection portion, the second heat dissipation portion, and the second tip portion correspond to 2/3 of the connection portion, the heat dissipation portion, and the tip portion, respectively. The first connecting portion, the second heat dissipating portion and the second tip portion are integrally formed. The first connecting portion is connected with the heat dissipation column, the second heat dissipation portion is connected with the first connecting portion, and the width of the second heat dissipation portion is increased towards a direction away from the first connecting portion, for example, the width of the second heat dissipation portion is gradually increased towards a direction away from the first connecting portion; for another example, the width of the second heat sink member is increased stepwise toward a direction away from the first connection portion. For example, the second heat sink member has a side face inclined downward. The second tip end is connected with the second heat dissipation part, two first corner ends are formed on two sides of the second tip end connected with the second heat dissipation part, and a first heat dissipation distance formed between the two first corner ends is 2 times of the width of the middle area of the second heat dissipation part. The width of the second tip part is reduced towards the direction far away from the second heat radiating part and forms a tip, for example, the width of the second tip part is reduced towards the direction far away from the second heat radiating part and forms a tip at the tail end, so that the two first corner ends can form a wider middle part, the tail end of the second tip part is in a tip shape, a petal-shaped structure is integrally formed, meanwhile, the wider middle part also has a larger area to be in contact with air, and the heat radiating efficiency is better. Preferably, the heat dissipation column and the heat dissipation block are made of aluminum profile materials, and further, the heat dissipation column and the heat dissipation block can be integrally formed in a die sinking processing mode, namely the heat dissipation seat, the flower-shaped heat dissipation body, the heat dissipation piece and the like are integrally formed. Therefore, the structural strength of the heat dissipation member can be ensured, and the production is convenient to implement.
