SUMMARY OF THE INVENTION To address the above technical problems, the purpose of this disclosure is to provide a heat dissipation module and LED lighting equipment capable of promptly cooling the lighting assembly to prevent the equipment from being adversely affected by continuous temperature rise during operation. To achieve the above purpose, this disclosure provides a heat dissipation module, adapted for use with a lighting assembly, comprising: a main housing, covering a periphery of the lighting assembly, forming a fluid channel between the lighting assembly and the main housing, wherein the main housing is provided with a medium inlet and a medium outlet that are both fluidically connected to the fluid channel, wherein the medium inlet is utilized for inputting a cooling medium, and the medium outlet is utilized for outputting the cooling medium; fan blades, rotatably connected to the main housing, positioned relatively close to the medium inlet, and connected to a drive component for rotation, wherein the fan blades are utilized to disperse the cooling medium, and to facilitate a flow of the dispersed cooling medium through the fluid channel and over a surface of the lighting assembly for heat dissipation. It is worth mentioning that the main shell disposed outside the light assembly forms a heat dissipation channel, that is, the above-mentioned fluid channel, and the fan blades improve the uniformity of the flow of the cooling medium in the fluid channel, improving the heat dissipation effect of the light assembly.

Additionally, terms like "first," "second," etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance. Referring to FIG. 1 to FIG. 3, one embodiment of the heat dissipation module provided by the present disclosure is described. This heat dissipation module can promptly cool a lighting assembly 567, preventing adverse effects due to continuous temperature rise during operation. In this embodiment, the heat dissipation module is installed at the lighting assembly 567 and comprises firstly a main housing (1 and 2) covering the periphery of the lighting assembly 567, forming a fluid channel 300 between the lighting assembly 567 and the main housing. Further, the main housing features a medium inlet 100 and a medium outlet 200. The medium inlet 100 is used to input a cooling medium, and the medium outlet 200 is used to output the cooling medium. And fan blades 3 are connected to a drive component 4 for rotation. The fan blades 3 are used to disperse the cooling medium, causing it to flow through the fluid channel 300 over the surface of the lighting assembly 567 for heat dissipation. In this embodiment, the fan blades 3 are positioned relatively close to the medium inlet 100. When the cooling medium is input, the continuously rotating fan blades 3 push the cooling medium toward the medium outlet 200, causing it to flow through the fluid channel 300 and cool the lighting assembly 567 as described above. Notably, in this embodiment, the lighting assembly 567 can be used for illumination or simply as an indicator on a device. However, it is certain that elements tend to heat up when emitting light, so this heat dissipation module addresses the issue of overheating. And the cooling medium in this embodiment is not limited to a specific form or type. It can be gaseous or liquid, as long as it can flow through the fluid channel 300. If it is liquid, a corresponding liquid outlet can be added to the device. In another embodiment, the main housing includes a first housing 1 and a second housing 2, which are connected together. The medium inlet 100 is provided on the first housing 1, and the medium outlet 200 is provided on the second housing 2. The fan blades 3 are located inside the first housing 1, and the lighting assembly 567 is positioned near the side of the first housing 1 that is close to the second housing 2. The second housing 2 covers the periphery of the lighting assembly 567 to form the fluid channel 300. It is understandable that dividing the main housing into a first housing 1 and a second housing 2 facilitates production and assembly of internal parts. Of course, the main housing can also be composed of more sub-housings. In this embodiment, the first housing 1 and the second housing 2 are just one way of implementation. Technicians can adjust the number of sub-housings based on actual needs. The lighting assembly 567 can be attached to the first housing 1 in various ways, such as by screws, bolts, and / or clip structures. This aspect is well known in the art and is not the focus of this disclosure, so it is not elaborated further here. The connection between the first housing 1 and the second housing 2 typically uses a threaded connection, as illustrated. Both the first housing and the second housing 2 are equipped with corresponding threads, allowing them to be screwed together for easy assembly and maintenance. Other connection methods can also be used. A power supply terminal and a control terminal are usually placed between the second housing 2 and the first housing 1. The power supply terminal powers the fan blades 3 and the lighting assembly 567, while the control terminal handles information processing and output. If these terminals are placed in the first housing 1, they must be positioned in a manner to avoid interference with the rotating fan blades 3. In one embodiment, referring to FIG. 1 and FIG. 3, the first housing 1 includes a top housing 12 and a middle housing 11. The middle housing 11 connects to the second housing 2, accommodating the lighting assembly 567 and fan blades 3 on opposite sides. The top housing 12 connects to the middle housing 11 on the side of the fan blades 3, providing space for their movement. The connection between the top housing 12 and the middle housing 11 is typically detachable, like a snap-fit connection. The connection between the middle housing 11 and the lighting assembly 567, and between the middle housing 11 and the fan blades 3 will be detailed later. The space between the top housing 12 and the middle housing 11 is configured to fit the fan blades 3. The fan blades 3 in this embodiment have decreasing blade height from the center to the periphery and are convex toward the top housing 12 in an overall profile, increasing airflow area and efficiency. The inner side of the top housing 12 is accordingly curved to match the fan blades 3, further improving airflow and preventing cooling medium stagnation. Referring to FIG.5, the middle housing 11 features a through-hole extending into an annular flange 111, at least partially accommodating the drive component 4, whose drive shaft connects to the fan blades 3 along the extension direction of the annular flange 111. As shown in FIG. 5, the annular flange 111 supports the drive component 4, wherein the drive component 4 is circumferentially limited and isolated by the annular flange 111, reducing vibrations that occurs during the starting of the drive component 4, which could affect surrounding components during operation. In another embodiment, the middle housing 11 features multiple flow channels 110 circumferentially at its periphery, which are fluidly connected to the fluid channel 300. Notably, the flow channels 110 ensure an even distribution of the cooling medium. During the rotation of the fan blades 3, the cooling medium is driven by the fan blades 3 through the flow channels 110, and flows by the lighting assembly 567, enabling a heat exchange between the cooling medium and the lighting assembly 567 to achieve an effective cooling. Configurations like number and width of the flow channels 110 can be adjusted based on the actual dimension of the middle housing 11 and thus not limited here. Alternatively, the direction of the flow channels 110 can either be parallel to or at a preset angle to a central axis 15 of the middle housing 11. Understandably, in the above configurations, the extension direction of the flow channels 110 may be parallel or not parallel to the central axis 15 of the middle housing 11. The flow direction of the cooling medium may be adjusted through the different configurations, and by changing the preset angle, a targeted heat dissipation can be achieved according to the shape, profile or overheating-prone positions of the lighting assembly 567. The periphery of the middle housing 11 is divided into a first ring 1101 and a second ring 1102 by the flow channels 110 in a thickness direction. The first ring 1101 docks with the edge of the second housing 2, while the second ring 1102 docks with the edge of the lighting assembly 567. Specifically, referring to FIG. 4, the first ring 1101 and the second ring 1102 can be considered as an outer ring and an inner ring of the middle housing 11, respectively. The first ring 1101 and the second ring 1102 of the middle housing 11 are connect by multiple flow guide plates 14. By altering the deflection of the flow guide plates 14, the preset angle mentioned above can be altered, which is perceivable in the figure. And similarly, the size of the flow channels 110 can also be altered by altering the spacing interval of the flow guide plates 14, which is not further detailed here. The first ring 1101 and the second ring 1102 were docked to the second housing 2 and the lighting assembly 567, respectively. But it can be understood that the docking referred to in this embodiment does not necessarily mean that there is a connection between two counterparts, but may also be butting or abutting relation between two counterparts, as long as the second housing 2 and the lighting assembly 567 can feature a relative connection with the middle housing 11, ensuring that they do not fall apart. In one embodiment, referring to FIG. 1, the lighting assembly 567 includes a support 5, a lighting board 6, and a first cover 7. The support 5 attaches to the first housing 1, with the lighting board 6 mounted on the support 5 and the first cover 7 enclosing the lighting board 6 and connecting to the first housing 1. Understandably, the lighting board 6 is provided with lamp beads, electrically connected to the lighting board 6. When provided with electricity, the lamp beads light up for illumination or indication. The first cover 7 protects the lamp beads, typically made transparent or translucent to avoid blocking light. In this embodiment, the positional relationship between the support 5 and the first cover 7 is not limited. The first cover 7 may cover the periphery of the support 5 or may not wholly cover the support 5. For example, when the support 5 is rod-shaped, the two ends of the rod may be respectively connected to the first housing 1 and the lighting board 6, and the first cover 7 may just cover the lighting board 6. Similarly, according to the different forms of support 5, there may also be other implementations. Referring to FIG. 1, in this embodiment, the support 5 is hollow and conical, with the lighting board 6 fixed inside it. The first cover 7 encloses both the support 5 and the lighting board 6. In this embodiment, both the first cover 7 and the support 5 can be transparent or translucent, ensuring proper light emission. And the connection between the lighting board 6 and the support 5 is also shown in the figure, wherein three connecting ends constitute a triangular array, ensuring that the lighting board 6 is centered and stabilized, preventing misalignment. Without affecting the technical effect of this embodiment, the positions of the connection, the number of the connecting ends may be adjusted. At the same time, the three connecting ends extending from the support 5 are used to connect to the first cover 7 and the middle housing 11. Of course, the corresponding connecting ends on the middle housing 11 can either be integrally formed on the middle housing 11 or be fasteners assembled to it. In another embodiment, the second ring 1102 and the first cover 7 have corresponding protrusions and recesses for alignment, preventing misalignment or rotation. For example, as shown in the figures, the second ring 1102 is provided with protruding edges 13, and the first cover 7 is provided with corresponding recesses 71. During the assembly by an operator, the support 5 and the lighting board 6 are first fixed together, followed by docking the support 5 to the middle housing 11, sleeving the first cover 7 onto the support 5, and aligning the connecting ends of the middle housing 11, of the support 5, and of the first cover 7, then fixing with corresponding fasteners. Without the concave-convex structure, the alignment of the connecting ends is not very efficient, and iterations are needed to achieve an alignment. By providing the concave-convex structure, the operator first aligns the support 5 and other parts with the first cover 7, and then align the protruding edges 13 with the recesses 71 and snap them together, to improve the assembly efficiency. In another embodiment, the medium outlet 200 on the second housing 2 is configured as a reducing nozzle, decreasing in diameter along the output direction of the cooling medium. The contour of the first cover 7 near the medium outlet 200 is adapted to this reducing nozzle. Notably, by providing the reducing nozzle, the overall size of the device can be reduced to a certain extent, improving the portability. And by exchanging the second housing 2, the lighting effect can also be modified, such as concentrating the lighting by providing non-transparent portions or achieving aesthetic lighting effects by providing decorative patterns on the second housing 2. Refer to FIG. 1 and FIG. 2, the present disclosure also provides an LED lighting equipment incorporating one of the heat dissipation modules described above, effectively cooling the lighting assembly 567 of the LED lighting equipment. It should be noted that the above embodiments can be freely combined as 5 needed. The preferred embodiments of the present disclosure are illustrative and not limiting. Modifications and variations made by those skilled in the art within the principles of the present disclosure are included within the scope of protection.
