Technical Field
[0001] The utility model relates to the technical field of lamp heat dissipation, in particular to a heat dissipation structure for an LED lamp. Background Art
[0002] An LED lamp is a lighting device that uses light-emitting diodes (LEDs) as light sources. Compared with traditional incandescent lamps, fluorescent lamps, etc., LED lamps have various advantages, such as high energy efficiency, long lifespan, high durability, fast response speed, etc. Therefore, they are widely used in various lighting applications. The energy efficiency of LED light sources is much higher than that of traditional lamps, and they can convert more electrical energy into light energy, reducing energy consumption. In addition, the lifespan of LED lamps is usually over 50,000 hours, which is much higher than that of traditional lamps, reducing the replacement frequency and maintenance cost.
[0003] However, LED lamps generate a large amount of heat when emitting light, especially some spotlights generate more heat. Therefore, effective heat dissipation for LED lamps is required. The existing heat dissipation method is mainly to set multiple heat dissipation holes on the lamp housing to increase the contact area with air, thereby achieving the heat dissipation effect.
[0004] Although this heat dissipation method can complete basic heat dissipation operations, it has obvious deficiencies. The effect of the heat dissipation holes depends on the air flow in the surrounding environment. In a windless or enclosed environment, the function of the heat dissipation holes will be greatly weakened because the air flow is restricted, the heat cannot be quickly discharged, and the heat accumulates inside the lamp, thus affecting the service life of the LED lamp. Summary of the Utility Model
[0005] In order to make up for the above deficiencies, the utility model provides a heat dissipation structure for an LED lamp, aiming to improve the problem that the effect of the existing heat dissipation holes depends on the air flow in the surrounding environment, and in a windless or enclosed environment, the function of the heat dissipation holes will be greatly weakened because the air flow is restricted and the heat cannot be quickly discharged.
[0006] To achieve the above object, the utility model provides the following technical solutions:

The transparent lamp cover 2 can effectively protect the internal LED lamp board 17 and other electronic components from dust, moisture and external physical damage (such as impact), extend the service life of the lamp, and at the same time can evenly diffuse the light emitted by the LED lamp board 17, reduce glare and shadows, and improve the lighting quality and visual comfort;
[0032] The mounting shell 3, which is arranged at the upper part of the housing 1, is used to fix and protect the internal components;
[0033] The mounting shell 3 is installed at the upper part of the housing 1, used to fix and protect the internal components, improve the stability of the overall structure of the lamp, ensure that each component is firmly connected, and reduce loosening or damage caused by vibration or impact;
[0034] The mounting block 9, which is arranged at the upper part of the mounting shell 3, is used to provide a stable mounting foundation;
[0035] The mounting block 9 is installed at the upper part of the mounting shell 3, used to provide a stable mounting foundation. The mounting block 9 provides a solid platform, enabling the mounting shell 3 to be firmly fixed on the housing 1, enhancing the structural stability of the entire lamp;
[0036] The socket 10, which is arranged at the upper part of the mounting block 9, is used to connect the power supply and support the electrical access of the LED lamp;
[0037] The socket 10 is fixedly connected to the upper part of the mounting block 9. The design of the socket 10 makes the power connection more convenient. Users can easily insert the power plug into the socket 10 without complex wiring operations, greatly improving the installation efficiency;
[0038] The heat dissipation plate 11, which is arranged inside the mounting shell 3, is used to dissipate and conduct the heat generated by the LED;
[0039] The heat dissipation plate 11 is installed inside the mounting shell 3. Through its large surface area, the heat generated during the operation of the LED is quickly dissipated, preventing heat from concentrating in one place, thereby improving the overall heat dissipation efficiency;
[0040] Refer to Figure 2, a heat dissipation mechanism 4 is provided inside the mounting shell 3 to further enhance the heat dissipation effect and ensure the heat dissipation requirements of the lamp under high power conditions. The heat dissipation mechanism 4 includes a fixed shell 401 fixedly connected inside the mounting shell 3. A heat dissipation fan 402 is fixedly connected inside the fixed shell 401. Heat dissipation fins 403 are arranged on the left side outside the heat dissipation fan 402. The heat dissipation fins 403 are installed inside the mounting shell 3. An LED lamp board 17 is installed inside the housing 1. A first external thread 5 is fixedly connected to the left side outside the mounting shell 3. A first internal thread 6 is provided inside the housing 1. The first external thread 5 and the first internal thread 6 are in threaded connection. A second external thread 7 is fixedly connected to the right side outside the mounting shell 3. A second internal thread 8 is provided inside the mounting block 9. The second external thread 7 and the second internal thread 8 are in threaded connection;
[0041] During the use of the LED lamp, by starting the heat dissipation fan 402 installed inside the fixed shell 401, external air is inhaled and then delivered to the upper part of the heat dissipation fins 403. The air is cooled and heat-exchanged through the heat dissipation fins 403, and then the cooled air is delivered inside the housing 1 to cool the LED lamp board 17 installed inside the housing 1. At the same time, the excess hot air inside the housing 1 will be discharged through the heat dissipation plate 11, realizing the operation of facilitating the heat dissipation of the LED lamp. Different from the traditional heat dissipation method that only sets multiple heat dissipation holes on the outer shell of the lamp, this method can also complete the heat dissipation operation of the lamp in a windless or airtight environment, significantly extending the service life of the LED lamp. By setting the first external thread 5 and the first internal thread 6, it is convenient to install the mounting shell 3. By setting the second external thread 7 and the second internal thread 8, it is convenient to install the mounting block 9.
[0042] Refer to Figure 4 , a replacement mechanism 13 is provided inside the heat dissipation plate 11 to facilitate the replacement and maintenance of the LED lamp components. The replacement mechanism 13 includes a moving block 1301 slidably connected inside the heat dissipation plate 11. A plug rod 1305 is fixedly connected to the left side outside the moving block 1301. A telescopic rod 1302 is fixedly connected inside the heat dissipation plate 11. The top of the telescopic rod 1302 is fixedly connected to the outside of the moving block 1301. A spring 1303 is sleeved outside the telescopic rod 1302. A handle 1304 is fixedly connected to the outside of the moving block 1301. A jack 14 is opened inside the mounting shell 3. The plug rod 1305 is inserted into the jack 14. A first through hole 15 is opened on the front side inside the heat dissipation plate 11. The handle 1304 is slidably connected inside the first through hole 15. A second through hole 16 is opened inside the heat dissipation plate 11. The plug rod 1305 is slidably connected inside the second through hole 16. An installation cavity 12 is opened inside the heat dissipation plate 11. The telescopic rod 1302 is fixedly connected inside the installation cavity 12. The moving block 1301 is slidably connected inside the installation cavity 12.
[0043] When it is necessary to clean the dust attached to the outside of the heat dissipation plate 11, by moving the grip 1304, the movement of the grip 1304 drives the externally fixed moving block 1301 to move inside the installation cavity 12. During the movement of the moving block 1301, it will squeeze the telescopic rod 1302 fixed to the outside on the right side, causing the telescopic rod 1302 to contract. At the same time, when the telescopic rod 1302 contracts, it drives the externally sleeved spring 1303 to contract synchronously, storing a certain amount of elastic potential energy. At the same time, when the moving block 1301 moves, it drives the insertion rod 1305 fixed to the outside on the left side to move, so that the insertion rod 1305 disengages from the inside of the jack 14, thus completing the disassembly of the heat dissipation plate 11. The disassembled heat dissipation plate 11 can be conveniently cleaned of external dust. Tools such as compressed air, a soft brush or a wet cloth can be used to ensure that the dust and dirt on the surface of the heat dissipation plate 11 are thoroughly removed, thereby preventing dust accumulation, ensuring that the surface of the heat dissipation plate 11 can fully contact the air, maintaining efficient heat conduction and dissipation capabilities, and improving the overall heat dissipation efficiency. After the cleaning is completed, when reinstalling the heat dissipation plate 11, first insert the heat dissipation plate 11 into the inside of the installation shell 3 so that it is in the correct position. Then, release the grip 1304. During the process of releasing the grip 1304, the reaction force of the spring 1303 will push the insertion rod 1305 back into the inside of the jack 14 to ensure that the heat dissipation plate 11 is firmly fixed inside the installation shell 3. In this way, the installation of the heat dissipation plate 11 can be completed through simple operations, ensuring its stable operation in the device, realizing the convenience of cleaning the dust attached to the outside of the heat dissipation plate 11, preventing dust accumulation, ensuring that the surface of the heat dissipation plate 11 can fully contact the air, maintaining efficient heat conduction and dissipation capabilities, and improving the heat dissipation efficiency.
[0044] Working principle: During the use of the LED lamp, the cooling fan 402 installed inside the fixed shell 401 is started. The cooling fan 402 sucks in the external air, and then conveys the air to the upper part of the heat dissipation fins 403. The heat dissipation fins 403 cool the air and perform heat exchange. Then, the cooled air is conveyed into the shell 1 to cool the LED lamp board 17 installed inside the shell 1. At the same time, the excess hot air inside the shell 1 will be discharged through the heat dissipation plate 11, realizing the operation of facilitating the heat dissipation of the LED lamp. Different from the traditional heat dissipation method that only sets multiple heat dissipation holes on the outer shell of the lamp, this method can also complete the heat dissipation operation of the lamp in a windless or airtight environment, extending the service life of the LED lamp. Then, when it is necessary to clean the dust attached to the outside of the heat dissipation plate 11, by moving the grip 1304, the grip 1304 moves and drives the externally fixed moving block 1301 to move inside the installation cavity 12. When the moving block 1301 moves, it squeezes the telescopic rod 1302 fixed to the outside on the right side. When the telescopic rod 1302 contracts, it drives the externally sleeved spring 1303 to contract synchronously. At the same time, when the moving block 1301 moves, it drives the plug rod 1305 fixed to the outside on the left side to move, so that the plug rod 1305 can be disengaged from the inside of the jack 14 to complete the disassembly of the heat dissipation plate 11. After the cleaning is completed, when installing the heat dissipation plate 11, first, insert the heat dissipation plate 11 into the installation shell 3, and then, release the grip 1304, and the plug rod 1305 will be inserted into the inside of the jack 14 under the reaction force of the spring 1303, realizing the convenience of cleaning the dust attached to the outside of the heat dissipation plate 11, preventing dust accumulation, ensuring that the surface of the heat dissipation plate 11 can fully contact the air, maintaining high-efficiency heat conduction and dissipation capabilities, and improving the heat dissipation efficiency.

Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
