[0002] Flexible circuit boards are the only solution to meet the miniaturization and mobility requirements of electronic products. Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates. Flexible circuits provide excellent electrical properties and can meet the design needs of smaller and higher-density installations. They also help reduce assembly processes and enhance reliability. Flexible circuit boards can greatly reduce the size and weight of electronic products and are suitable for the development of electronic products towards high density, miniaturization, and high reliability.

This heat-dissipating LED flexible circuit board improves the heat dissipation speed and efficiency of the entire circuit board, allowing for better performance of the entire device while reducing energy consumption and cost. However, the heat dissipation method designed in this utility model only dissipates heat from the lower surface of the board itself, leaving a limited cooling effect on the LED lamp beads on the upper surface.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 3 As shown, a heat-dissipating LED flexible circuit board includes a plate body 1 and a mounting shell 2 arranged on the outside of the plate body 1. The upper surface of the mounting shell 2 is fixedly connected to a transparent plastic plate 3, and the inner bottom of the mounting shell 2 is fixedly connected to four supporting pads 4. The inside of the transparent plastic plate 3 extends to the outside and is provided with four fixing mechanisms 5. The right side of the upper surface of the mounting shell 2 is fixedly connected to an additional plate 6, and the left outer surface of the additional plate 6 is fixedly connected to a micro cooling fan 7. The outer surface of the fixed side plate on the front side of the mounting shell 2 extends to the inner surface and is provided with a wiring hole for wiring of the plate body 1. The outer surface of the additional plate 6 is penetrated by a through groove. The fixing mechanism 5 includes a fixing screw 51 threadedly connected to the inside of the transparent plastic plate 3 and extending to the outside. The upper end of the fixing screw 51 is provided with a cross slot 52, and the lower end of the fixing screw 51 is provided with a cross slot 52. The end is rotatably connected to a rotating block 53. The mounting shell 2 outside the plate body 1 can provide better protection for the plate body 1, and the transparent adhesive plate 3 will not affect the light transmittance of the plate body 1. If the upper and lower surface temperatures of the plate body 1 are too high, the micro-cooling fan 7 can be turned on for heat dissipation. During heat dissipation, the micro-cooling fan 7 blows air from the outside to the inside, and the heat is discharged from the lower surface of the plate body 1 through the upper surface and finally reaches the open port above the mounting plate 6. This design can form an air duct, which can effectively reduce the heat on the upper and lower surfaces of the plate body 1. The fixing mechanism 5 can achieve better fixing and disassembly effects. When fixing, the fixing screw 51 can be rotated using a cross screwdriver and a cross slot 52 to drive the rotating block 53 to press down, and together with the support pad 4, the plate body 1 is limited and fixed. When disassembling, just screw the fixing screw 51 in the opposite direction.

[0022] like Figure 2-Figure 4 As shown, the lower surface of the rotating block 53 is fixedly connected with a rubber pad 8, and the rubber pad 8 is fixed by bonding. The rubber pad 8 can prevent the rotating block 53 and the plate body 1 from having hard contact. The rubber pad 8 is fixed by bonding, which makes it easy to replace the rubber pad 8 that is prone to aging.

[0023] Furthermore, screw holes 9 are provided through the upper and lower surfaces of both sides of the mounting shell 2, and fixing screws can be inserted into the screw holes 9. The provision of the screw holes 9 can facilitate the fixing connection between the mounting shell 2 and the plate body 1 at the mounting position.

[0024] Furthermore, two fixing bars 10 are fixedly connected to the right outer surface of the mounting plate 6 , and a slot 11 is formed on the outer surface of the fixing bar 10 .

[0025] Furthermore, a filter screen 12 is provided between the fixing bars 10 , and the width of the filter screen 12 is sufficient to be slidably connected to the inside of the two slots 11 , and the width of the slots is greater than the thickness of the frame of the filter screen 12 .

[0026] Working principle: When using the heat dissipation type LED flexible circuit board, first, if the temperature of the upper and lower surfaces of the board body 1 is too high, the micro-cooling fan 7 can be turned on for heat dissipation. During heat dissipation, the micro-cooling fan 7 blows air from the outside to the inside, and the heat is discharged from the lower surface of the board body 1 through the upper surface, and finally reaches the open port above the mounting plate 6. This design can form an air duct, which can effectively reduce the heat on the upper and lower surfaces of the board body 1. The fixing mechanism 5 can achieve better fixing and disassembly effects. When fixing, the fixing screw 51 can be rotated using a cross screwdriver and a cross slot 52 to drive the rotating block 53 to press down, and together with the support pad 4, the board body 1 is limited and fixed. When disassembling, just twist the fixing screw 51 in the opposite direction. The filter 12 can filter the dust when the micro-cooling fan 7 dissipates heat, reduce the dust from entering the interior of the mounting shell 2, and prevent dust from accumulating on the surface of the board body 1. The filter 12 can be slidably connected to the inside of the card slot 11. This is the working principle of the heat dissipation type LED flexible circuit board.
