Description

Technical Field

[0001] This utility model relates to the field of LED lamp heat sink technology, specifically to an LED lamp heat sink with a wide range of applications. Background Technology

[0002] The basic principle of LED lamp heat sinks is to conduct the heat generated by the LED chip to the heat sink through the thermal conductivity of the material, and then dissipate the heat into the air through heat transfer and convection between the heat sink and the air. This design can quickly balance the temperature inside the lamp, ensuring that the LED chip works within a suitable temperature range and preventing light decay, color accuracy problems, and damage to other electronic components caused by overheating.

[0003] Existing LED heat sinks have the following drawbacks when in use:

[0004] 1. In the existing technology, heat dissipation fins are generally flat fins, which have a small contact area with the air and poor heat dissipation.

[0005] 2. In the prior art, in order to increase the air circulation efficiency, a cooling fan is generally installed on one side of the heat dissipation fins. The cooling fan increases the air circulation speed. However, the heat dissipation fins blow air towards the back plate of the heat sink, which results in greater resistance and increases the generation of noise.

[0006] 3. Existing cooling fans lack a buffer structure, and the vibration generated when the cooling fan is running will increase the noise.

[0007] Therefore, we propose a widely applicable LED lamp heat sink. Utility Model Content

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] This embodiment is a widely applicable LED lamp heat sink.

[0030] like Figure 1-4 As shown, the device includes a radiator backplate 1, with heat dissipation fins 2 fixedly installed on the upper outer surface of the radiator backplate 1, and a buffer assembly 3 fixedly installed on one end of the outer surface of the radiator backplate 1. The buffer assembly 3 includes a base 6, a mounting cavity 7, a movable plate 8, a damper 9, a compression spring 10, a guide ring 11, and a guide rod 12. The base 6 is fixedly installed on one end of the outer surface of the radiator backplate 1, and a mounting plate 4 is provided on the upper part of the buffer assembly 3. The mounting plate 4 is located at one end of the heat dissipation fins 2, and cooling fans 5 are fixedly installed on the mounting plate 4 at equal intervals.

[0031] The heat dissipation fins 2 are S-curve shaped; there are two sets of guide rings 11, guide rods 12, dampers 9, and compression springs 10. The two sets of guide rings 11 are fixedly installed on the left and right ends of the upper outer surface of the damper 9. The guide rods 12 pass through the guide rings 11, and the two sets of guide rods 12 are fixedly installed on the left and right ends of the lower outer surface of the mounting plate 4. The two sets of guide rods 12 are fixedly installed on the left and right ends of the upper outer surface of the movable plate 8. The mounting cavity 7 is opened inside the base 6, and the damper 9, compression springs 10, and movable plate 8 are all located in the mounting cavity. In section 7, two sets of dampers 9 are fixedly installed between the left and right ends of the bottom of the mounting cavity 7 and the left and right ends of the lower outer surface of the movable plate 8. The compression spring 10 is movably sleeved on the outer wall of the damper 9. The lower outer surface of the compression spring 10 is fixedly connected to the bottom of the mounting cavity 7, and the upper outer surface of the compression spring 10 is fixedly connected to the lower outer surface of the movable plate 8. The outer wall of the guide rod 12 is slidably connected to the guide ring 11. The lower outer surface of the movable plate 8 is elastically connected to the bottom of the mounting cavity 7 through the damper 9 and the compression spring 10.

[0032] It should be noted that this utility model is a widely applicable LED lamp heat sink. The heat sink fins 2 are curved, which increases the contact area with the air and improves the heat dissipation efficiency. The heat dissipation fan 5 is installed at one end of the heat sink back plate 1, so that the heat dissipation air duct is parallel to the heat sink fins 2, reducing wind resistance and noise generation. The buffer component 3 is provided so that when the heat sink fan 5 is running, the guide rod 12 slides along the guide ring 11. The guide rod 12 drives the movable plate 8 to squeeze the damper 9 and the compression spring 10. The damper 9 can effectively absorb and disperse vibration energy, reduce the vibration transmitted to the heat sink back plate 1 and the heat sink fins 2, thereby reducing the noise level.
