[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Refer to Figure 1 - Figure 4 As shown in the figure, an embodiment provided by the present invention: an LED surface light source with an internal heat dissipation structure includes a lamp housing 2. The lamp housing 2 is a prior art and plays a protective role for the LED surface light source to ensure the normal use of the LED surface light source. A third through slot 7 is opened on the rear surface of the lamp housing 2. The inner wall of the front end of the lamp housing 2 is in contact with a lamp shade 1. The lamp shade 1 is a prior art and an LED surface light source is installed inside it. Through its cooperation with the lamp housing 2, the stability of the LED surface light source during use can be ensured. A second through slot 6 is opened on the rear surface of the lamp shade 1, and a rectangular slot 5 is opened on the right surface of the lamp shade 1. A filter assembly 3 is arranged on the upper surface of the lamp housing 2, and a disassembly and assembly component 4 is arranged on the inner wall of the lamp housing 2. The disassembly and assembly component 4 includes a push plate 47. When the lamp shade 1 and the lamp housing 2 are installed together, the push plate 47 will always abut against the fixed plate 46, thereby ensuring the stability of the heat sink 45. The push plate 47 is fixedly connected to the inner wall of the lamp housing 2. The front surface of the push plate 47 is in contact with a fixed plate 46. The fixed plate 46 is in contact with the inside of the second through slot 6. The lower surface of the fixed plate 46 is fixedly connected to a heat sink 45. The heat sink 45 is a prior art and has good heat conduction performance, and can quickly absorb the heat generated by the heat source and conduct it to the entire heat sink 45. The front surface of the heat sink 45 is in contact with the rear surface of the lamp shade 1.

[0034] Refer to Figure 1 、 Figure 3 - Figure 4 、 Figure 6, the filtering component 3 includes a ventilation pipe 31. A heat dissipation fan is arranged inside the ventilation pipe 31, which can ensure rapid heat dissipation and improve the practicality. The ventilation pipe 31 is fixedly connected to the upper surface of the lamp housing 2. A filter plate 32 is in contact with the upper surface of the ventilation pipe 31. The filter plate 32 can prevent external dust from entering the interior of the lamp housing 2 and improve the heat dissipation efficiency. An insertion slot 35 is formed in the upper surface of the ventilation pipe 31, and an annular groove 36 is formed in the inner wall of the insertion slot 35. A round rod 33 is fixedly connected to the lower surface of the filter plate 32. The round rod 33 is in contact with the inner wall of the insertion slot 35. A rubber ring 34 is fixedly connected to the outer wall of the round rod 33. The rubber ring 34 has a certain elasticity, and its outer wall is set as an arc surface, which ensures that the filter plate 32 can be quickly installed and improves the practicality. The rubber ring 34 is in contact with the inner wall of the annular groove 36.

[0035] Refer to Figure 3 - Figure 4 , the disassembly and assembly component 4 further includes a clamping block 44. The clamping block 44 is slidably connected to the inner wall of the right end of the lamp housing 2. The left end of the clamping block 44 is in contact with the inner wall of the rectangular groove 5. A U-shaped connecting rod 41 is fixedly connected to the rear surface of the clamping block 44. The right end of the U-shaped connecting rod 41 penetrates and is slidably connected to the right end of the rear surface of the lamp housing 2. The outer wall of the left end of the U-shaped connecting rod 41 is slidably connected to the inner wall of the third through groove 7. The right surface of the clamping block 44 is set as an inclined surface. The set inclined surface ensures that the lamp cover 1 and the lamp housing 2 can be quickly installed and improves the convenience.

[0036] Refer to Figure 3 - Figure 5 , the disassembly and assembly component 4 further includes a circular plate 48. The circular plate 48 is rotatably connected to the inner wall of the rear end of the lamp housing 2. A first through groove 49 is formed in the rear surface of the circular plate 48. The first through groove 49 has a certain slope, which ensures that when the circular plate 48 rotates, the U-shaped connecting rod 41 can move along its slope. The outer wall of the front side of the left end of the U-shaped connecting rod 41 is slidably connected to the inner wall of the first through groove 49. A rotating rod 42 is fixedly connected to the rear surface of the circular plate 48. The rotating rod 42 penetrates and is rotatably connected to the rear surface of the lamp housing 2. A torsion spring 43 is sleeved on the outer wall of the rotating rod 42. The torsion spring 43 has a certain elasticity. Through its own elasticity, it ensures that when the lamp cover 1 and the lamp housing 2 are installed together, the clamping block 44 is always in contact with the inner wall of the rectangular groove 5, ensuring the stability of the limit. One end of the torsion spring 43 is fixedly connected to the rear surface of the lamp housing 2, and the other end of the torsion spring 43 is fixedly connected to the front surface of the rotating rod 42.

[0037] Working principle: When it is necessary to remove the heat sink 45 for replacement during use, only need to rotate the rotating rod 42. The rotating rod 42 will drive the circular plate 48 to rotate. At the same time, the rotating rod 42 will also drive the torsion spring 43 to undergo torsional deformation. At this time, the left end of the U-shaped connecting rod 41 will slide along the inclined surface of the first through groove 49 on the inner wall of the third through groove 7. The U-shaped connecting rod 41 will drive the clamping block 44 to move until the clamping block 44 disengages from the inner wall of the rectangular groove 5, so that the lamp cover 1 can be separated from the lamp housing 2. After the lamp cover 1 and the lamp housing 2 are separated, the push plate 47 will also disengage from the fixing plate 46, so that the heat sink 45 can be removed. During installation, place the fixing plate 46 into the inner wall of the second through groove 6 and make the heat sink 45 contact the rear surface of the LED lamp board arranged in the lamp cover 1. Then combine the lamp cover 1 and the lamp housing 2. When combining, the lamp cover 1 will push the clamping block 44 to move along its inclined surface. The subsequent result matching method is the same as above, but the direction of the structural matching is opposite. After the lamp cover 1 and the lamp housing 2 are installed, the front surface of the push plate 47 will contact the rear surface of the fixing plate 46 and always press against the fixing plate 46 to ensure the stability of the heat sink 45.

[0038] When dissipating heat from the LED surface light source, the filter plate 32 designed by the designer will filter the dust from the outside. When it is necessary to replace the filter plate 32, just directly pull the filter plate 32. The filter plate 32 will drive the round rod 33 to move. The round rod 33 will drive the rubber ring 34 to move. The rubber ring 34 will be extruded and disengaged from the inner wall of the annular groove 36, so that the filter plate 32 can be removed. It is fast and convenient, improving work efficiency. During installation, hold the filter plate 32 and insert the round rod 33 into the inner wall of the insertion slot 35. The subsequent structural matching method is the same as above.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. 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. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
