[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , a heat sink for an LED light-emitting diode lamp, comprising: a device housing 1, a controller 2 is installed on the front surface of the device housing 1, a detector 3 is installed in the inner cavity of the device housing 1, and a heat dissipation fan is installed in the inner cavity of the device housing 1; a replacement mechanism, the replacement mechanism is located at the top of the device housing 1 and is convenient for disassembly; a clamping mechanism, the clamping mechanism is located in the inner cavity of the device housing 1 and is used for fixing, the clamping mechanism includes a driving component and a moving component, the driving component is located in the inner cavity of the device housing 1 and is used to provide driving force for the moving component, and the moving component is located in the inner cavity of the device housing 1 and is used for fixing.

[0026] The driving component includes a servo motor 4 installed on the front of the device housing 1. On the back of the output shaft of the servo motor 4, a bidirectional lead screw 5 is installed. The servo motor 4 and the bidirectional lead screw 5 are connected by a coupling. There are two sets of the servo motor 4 and the bidirectional lead screw 5, and they are symmetrically distributed. The moving component includes a moving block 6 installed on the outer circle of the bidirectional lead screw 5. On one side of the moving block 6, a fixed block 7 is installed. Inside the cavity of the fixed block 7, a refrigeration sheet 8 is installed. The refrigeration sheet 8 is arranged at the bottom of the cooling fan. There are four sets of the moving blocks 6, and they are distributed in a rectangular array. There are two sets of the fixed blocks 7, and they are symmetrically distributed. A limiting component is installed in the cavity of the device housing 1. The limiting component includes a limiting rod 22 installed in the cavity of the device housing 1. There are two sets of the limiting rods 22, and they are symmetrically distributed. The limiting rods 22 are inserted into the cavity of the fixed block 7.

[0027] In the embodiment of the present utility model, when the servo motor 4 is started, the servo motor 4 drives the bidirectional lead screw 5 to rotate through the coupling, and drives the moving blocks 6 to approach or move away from each other. Since the moving block 6 is connected to the fixed block 7, the fixed block 7 will move along with the movement of the moving block 6. The limiting rods 22 in the device housing 1 ensure the stability and accuracy of the moving component during the movement. When the fixed blocks 7 approach each other, the refrigeration sheet 8 can be clamped and fixed.

[0028] Please refer to Figures 1-4 , the replacement mechanism includes a support frame 9 installed on the top of the device housing 1. Inside the cavity of the support frame 9, a first damper 10 is installed. On one side of the first damper 10, a connecting plate 11 is installed. A first spring 12 is installed between the support frame 9 and the connecting plate 11. Inside the cavity of the connecting plate 11, a connecting rod 13 is installed. On the top of the connecting rod 13, a handle 14 is installed. There are two sets of the support frame 9 and the connecting plate 11, and they are symmetrically distributed. At the bottom of the connecting rod 13, a fixing component is installed. The fixing component includes a clamping plate 15 installed at the bottom of the connecting rod 13. On one side of the clamping plate 15, a second damper 16 is installed. One side of the second damper 16 is connected to the inside of the device housing 1. A second spring 17 is installed between the device housing 1 and the clamping plate 15. There are two sets of the clamping plates 15, and they are symmetrically distributed. Inside the cavity of the clamping plate 15, a filter plate 18 is installed.

[0029] On one side of the device housing 1, a fixing plate 19 is installed. Inside the cavity of the fixing plate 19, a mounting hole 20 is opened. Inside the cavity of the mounting hole 20, a mounting rod 21 is threadedly connected. There are two sets of the fixing plates 19, and they are symmetrically distributed.

[0030] In the embodiment of the present utility model, by pulling the handle 14, the connecting rod 13 and the clamping plate 15 at the bottom are driven to move outward. During this process, the first damper 10 and the first spring 12 play a buffering and stabilizing role to ensure smooth movement.

[0031] During use, first, the device housing 1 is stably installed through the fixing plate 19 and the mounting rod 21. The mounting holes 20 opened on the fixing plate 19 allow the mounting rod 21 to be firmly fixed at a predetermined position through threaded connection, ensuring the stability of the entire radiator structure. This design not only facilitates the installation and disassembly of the radiator but also enables flexible application in different scenarios.

[0032] After installing the device housing 1 at the predetermined position, start the servo motor 4. The servo motor 4 drives the bidirectional lead screw 5 to rotate through the coupling and drives the moving blocks 6 to move closer to or away from each other. Since the moving blocks 6 are connected to the fixed blocks 7, the fixed blocks 7 will move along with the movement of the moving blocks 6. The limiting rod 22 inside the device housing 1 ensures the stability and accuracy of the moving assembly during movement. When the fixed blocks 7 move closer to each other, the refrigeration sheet 8 can be clamped and fixed. As the LED lamp works, the generated heat is monitored by the detector 3. If the temperature exceeds the preset threshold, the controller 2 can control the start of the cooling fan. Since the cooling fan is arranged on the top of the refrigeration sheet 8, with the start of the cooling fan, the cold air generated by the refrigeration sheet 8 can be blown into the LED lamp for rapid cooling.

[0033] Secondly, the design of the replacement mechanism greatly improves the convenience of lamp maintenance. When it is necessary to replace the filter plate 18 or perform cleaning and maintenance, the operator can pull the handle 14 to drive the connecting rod 13 and the clamping plate 15 at the bottom to move outward. During this process, the first damper 10 and the first spring 12 play a buffering and stabilizing role to ensure smooth movement. The clamping plate 15 and the device housing 1 are connected through the second damper 16 and the second spring 17, further enhancing the stability and safety of clamping. The filter plate 18 installed inside the clamping plate 15 can effectively block dust and other impurities from entering the lamp to protect the cleanliness of the lamp. After the clamping plate 15 is completely separated from the filter plate 18, the replacement or cleaning operation can be easily carried out.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits. The scope of the present invention is defined by the appended claims and their equivalents.
