[0002] The aluminum alloy heat dissipation module of LED lamp involves multiple fields, including science, thermodynamics, mechanical engineering and electronic engineering. Aluminum alloy is widely used in LED heat dissipation module due to its good thermal conductivity and mechanical properties. When selecting aluminum alloy, it is necessary to consider its thermal conductivity, strength, corrosion resistance and processability, and make reasonable optimization to meet the heat dissipation needs of LED lamps.

[0003] In the prior art, aluminum heat sink fins are the most common heat dissipation method. Although the heat sink fins have good thermal conductivity, in actual applications, due to factors such as the material structure and manufacturing process, the heat dissipation area is insufficient, which leads to poor heat dissipation efficiency. Especially in high-power LED lamps, there are some defects in the design of the heat dissipation structure. For example, the manufacturing process is subject to some restrictions, which makes the processing of aluminum alloy heat sink fins more difficult, resulting in high surface roughness or irregular shape, affecting the heat dissipation effect. At the same time, if the heat sink fins are too dense or too sparse, it will lead to low heat dissipation efficiency or insufficient structural strength. Therefore, an aluminum alloy heat sink module for LED lamps is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 and Figure 4The utility model provides an embodiment: an aluminum alloy heat dissipation module for an LED lamp, comprising a base 1, a copper heat sink 19 is fixedly connected to the top of the base 1, a mounting shell 2 is fixedly connected to the top of the copper heat sink 19, a cavity 22 is opened inside the mounting shell 2, a motor 20 is fixedly connected inside the cavity 22, a driving rod 24 is fixedly connected to the output end of the motor 20, a first bevel gear 18 is fixedly connected to one end of the driving rod 24, two bearing plates 16 are fixedly connected inside the cavity 22, a driven rod 15 is rotatably connected inside the two bearing plates 16, a second bevel gear 17 is fixedly connected to the outside of the driven rod 15, fan blades 21 are fixedly connected to both ends of the driven rod 15, a module body 23 is fixedly connected to the bottom of the base 1, and a protective component is installed at the bottom of the base 1.

[0033] Specifically, the copper heat sink 19 increases the heat dissipation area, making it easier for heat to be dissipated into the surrounding environment. The mounting shell 2 not only protects the internal motor 20 and other components, but also serves as a part of the wind circulation. The cavity 22 is used to fix and accommodate the motor 20 and other related components. When the motor 20 is started, it will drive the driving rod 24 and the first bevel gear 18 to rotate. When the first bevel gear 18 rotates, it will drive the second bevel gear 17 to rotate through the meshing connection, and at the same time make the driven rod 15 rotate accordingly. The driven rod 15 is rotatably connected in the cavity 22 through the bearing plate 16 to ensure that the driven rod 15 can rotate smoothly, thereby driving the fan blades 21 to rotate accordingly, so as to carry out air flow. The barrier net 6 prevents large particles of impurities in the external environment from entering the interior of the heat dissipation module, while allowing air circulation.

[0034] Reference Figure 2 and Figure 5 The protection component includes a bracket 3, the tops of the two brackets 3 are fixed to the bottom of the base 1, the two brackets 3 are internally rotatably connected with a threaded rod 10, the external thread of the threaded rod 10 is connected with a threaded sleeve 11, the bottom of the threaded sleeve 11 is fixedly connected with a plug plate 13, a sleeve plate 4 is provided at the bottom of the base 1, and connecting plates 7 are fixedly connected on both sides of the sleeve plate 4, and a limiting groove 8 is provided inside the connecting plate 7.

[0035] Specifically, the top of the bracket 3 is fixed to the bottom of the base 1, which provides a support point for the rotation of the threaded rod 10 and ensures the stability of the entire protective structure. The movement of the threaded sleeve 11 is controlled by rotating the threaded rod 10. When the threaded sleeve 11 moves, the plug plate 13 will also move accordingly, thereby inserting or pulling out the limiting groove 8 of the connecting plate 7. When the plug plate 13 is inserted into the limiting groove 8, the sleeve plate 4 will be fixed on the base 1, thereby protecting the module body 23 and preventing moisture, dust or other impurities from entering the interior of the module.

[0036] Reference Figure 3The corresponding position of the outside of the first bevel gear 18 is meshed with the outside of the second bevel gear 17, the inside of the bearing plate 16 is rotatably connected to the outside of the driven rod 15 through a rotating shaft, and the blocking net 6 is fixedly connected to both sides of the mounting shell 2.

[0037] Specifically, the first bevel gear 18 is connected to the second bevel gear 17 through external meshing. This connection allows the two to transfer power when rotating, so that they rotate at a corresponding speed and direction. The bearing plate 16 provides a stable support and rotation point for the driven rod 15, ensuring smooth rotation under the support of the bearing plate 16 without the need to withstand additional friction or resistance. The barrier net 6 prevents large particles of impurities, dust or insects in the external environment from entering the interior of the mounting shell 2, thereby protecting the internal copper heat sink 19.

[0038] Reference Figure 2 and Figure 6 A slide groove 14 is provided on one side of the bracket 3, the outside of the connecting plate 7 is slidably connected to the inside of the slide groove 14, the inside of the bracket 3 is fixedly connected to two slide rods 12, the inside of the threaded sleeve 11 is slidably connected to the outside of the two slide rods 12, one end of the threaded rod 10 extends to the outside of the bracket 3 and is provided with a handle 9, the outside of the plug plate 13 is inserted into the inside of the limit groove 8, and the bottom of the sleeve plate 4 is fixedly connected to the lens 5.

[0039] Specifically, the outside of the connecting plate 7 is slidably connected to the inside of the slide groove 14. This connection method ensures the stability and smoothness of the sleeve 4 during the sliding process, and prevents the sleeve 4 from accidentally falling off. The slide rod 12 provides guidance and support for the movement of the threaded sleeve 11, ensuring that the threaded sleeve 11 can remain vertical and stable when moving along the threaded rod 10. By rotating the handle 9, the user can easily control the rotation of the threaded rod 10, and then control the movement of the threaded sleeve 11. When the threaded sleeve 11 moves on the threaded rod 10, the plug plate 13 will move accordingly and be inserted into or pulled out of the limit groove 8, thereby realizing the fixation and unlocking between the sleeve 4 and the bracket 3, thereby realizing the protection of the module body 23.

[0040] Working principle: When the motor 20 is started, the driving rod 24 will drive the first bevel gear 18 to rotate, and through the gear transmission, the second bevel gear 17 will rotate, thereby driving the driven rod 15 to start rotating. The rotation of the driven rod 15 will drive the fan blades 21 at both ends to rotate, generating wind flow, so that the external airflow flows through the blocking net 6 to the inside of the mounting shell 2, and then passes through the copper heat sink 19 to increase its surface area, thereby exchanging the heat generated by the module body 23 when working, greatly improving the heat dissipation performance;

[0041] Secondly, slide the sleeve 4 inside the slide groove 14 through the connecting plate 7, so that the sleeve 4 protects the module body 23. When the sleeve 4 needs to be fixed, rotate the threaded rod 10 to make the threaded sleeve 11 threadedly connected to the threaded rod 10 move to the right. When the threaded sleeve 11 moves, it drives the plug plate 13 to be inserted into the limiting groove 8 inside the connecting plate 7, so as to fix the base 1 and the sleeve 4, and then the light source emitted by the module body 23 is emitted outward through the lens 5. At the same time, the protection of the sleeve 4 realizes the moisture-proof and waterproof effect of the module body 23.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
