[0002] A backlight is a light source component in a display device used to illuminate the screen. It is typically located behind the liquid crystal panel (LCD) to provide uniform backlighting, allowing users to clearly see images. Since liquid crystals themselves do not emit light, the backlight is a crucial part of LCD display technology.

[0003] When the backlight works for a long time, the backlight lamp assembly is prone to heat generation, which can lead to insufficient heat dissipation, accelerate the aging of the backlight lamp assembly, and result in insufficient brightness, affecting the display effect. Therefore, improvements are needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a double-sided heat dissipation and dustproof structure for backlight strips. This solves the problem that the backlight mounting brackets in the prior art often only have a single fixing function. When the backlight works for a long time, the backlight assembly is prone to heat up, resulting in insufficient heat dissipation, which can easily accelerate the aging of the backlight assembly, leading to insufficient brightness and affecting the display effect.

[0005] In view of this, the present invention provides a double-sided heat dissipation and dustproof structure for a backlight strip, including a light strip, wherein a plurality of light groups and a filter capacitor are fixedly installed on the top of the light strip, and a double-sided heat conduction and dustproof component and a fixing component are provided on the top and bottom of the light strip.

The thermally conductive base and the thermally conductive top cover are respectively installed at the bottom and top of the light strip, and the sealing gasket and the thermally conductive silicone are both fixedly installed on the inner side of the thermally conductive top cover.

[0007] Optionally, the top surface of the heat-conducting base abuts against the bottom surface of the light strip, and the heat-conducting cover is fitted onto the top of the light strip.

[0008] Optionally, the sealing gasket is made of polyurethane foam, and the bottom of the sealing gasket abuts against the top surface of the light strip.

[0009] Optionally, the bottom surface of the thermally conductive silicone abuts against the top surface of the light strip.

[0010] Optionally, the heat-conducting top cover has several openings and grooves in its middle section, and the openings and grooves are respectively matched with the shapes of the lamp assembly and the filter capacitor.

[0011] Optionally, the fixing component includes a slot, a vertical plate, a locking block, and an arc surface. The slot is formed on the side wall of the heat-conducting upper cover, the bottom of the vertical plate is fixedly connected to the side wall of the heat-conducting base, the locking block is fixedly connected to the inner side of one end of the vertical plate, and the arc surface is located on the inner side of the top of the vertical plate.

[0013] As can be seen from the above technical solutions, the embodiments of this utility model have the following advantages:

[0014] 1. The present invention relates to a double-sided heat dissipation and dustproof structure for a backlight strip. By setting up a double-sided heat-conducting and dustproof component, specifically, during use, heat is conducted by using a heat-conducting top cover, heat-conducting silicone and heat-conducting base to increase the heat dissipation area. At the same time, a sealing gasket is used to seal around the light strip to reduce dust intrusion.

[0024] The following describes in detail, with reference to the accompanying drawings, a double-sided heat dissipation and dustproof structure for a backlight strip according to an embodiment of the present invention.

[0025] Example 1

[0026] For easier understanding, please refer to Figures 1 to 4 This utility model provides an embodiment of a double-sided heat dissipation and dustproof structure for a backlight strip, including a light strip 1, a plurality of light groups 2 and a filter capacitor 3 fixedly installed on the top of the light strip 1, and double-sided heat conduction and dustproof components and fixing components provided on the top and bottom of the light strip 1.

[0027] The double-sided thermally conductive dustproof assembly includes a thermally conductive base 401, a thermally conductive top cover 402, a sealing gasket 403, and a thermally conductive silicone 404. The thermally conductive base 401 and the thermally conductive top cover 402 are respectively installed at the bottom and top of the light strip 1. The sealing gasket 403 and the thermally conductive silicone 404 are both fixedly installed inside the thermally conductive top cover 402. The top surface of the thermally conductive base 401 abuts against the bottom surface of the light strip 1, and the thermally conductive top cover 402 is fitted onto the top of the light strip 1. The sealing gasket 403 is made of polyurethane foam, and the bottom of the sealing gasket 403 abuts against the top surface of the light strip 1. The bottom surface of the thermally conductive silicone 404 abuts against the top surface of the light strip 1.

[0028] It should be noted that by setting up a heat-conducting base 401 and a heat-conducting top cover 402, which are fixed to the outside of the light strip 1, heat is conducted through the heat-conducting top cover 402, the heat-conducting silicone 404 and the heat-conducting base 401 during use, increasing the heat dissipation area. At the same time, the sealing gasket 403 is used to seal around the light group 2 of the light strip 1 to reduce dust intrusion.

[0029] In some embodiments, such as Figure 3 As shown, the heat-conducting top cover 402 has several openings 6 and grooves 7 respectively, and the openings 6 and grooves 7 are respectively matched with the shapes of the lamp group 2 and the filter capacitor 3.

[0030] It should be noted that the purpose of opening 6 is to expose the lamp group 2, while the groove 7 covering the filter capacitor 3 can protect the filter capacitor 3.

[0031] Example 2

[0032] In some embodiments, such as Figure 2 , Figure 3 , Figure 4As shown, the fixing component includes a slot 501, a vertical plate 502, a locking block 503, and an arc surface 504. The slot 501 is formed on the side wall of the heat-conducting upper cover 402. The bottom of the vertical plate 502 is fixedly connected to the side wall of the heat-conducting base 401. The locking block 503 is fixedly connected to the inner side of one end of the vertical plate 502. The arc surface 504 is located on the inner side of the top of the vertical plate 502. The shape of the locking block 503 matches the shape of the slot 501.

[0033] It should be noted that by setting up the cooperation between the card block 503 and the card slot 501, the heat-conducting base 401 and the heat-conducting top cover 402 can be connected, which facilitates the installation of the double-sided heat-conducting dustproof component.

[0034] Working principle: First, the heat-conducting base 401 and heat-conducting top cover 402 are connected and fixed to the outside of the light strip 1 by the cooperation of the slot 501 and the block 503. During use, the heat-conducting top cover 402, the heat-conducting silicone 404 and the heat-conducting base 401 are used to conduct heat and increase the heat dissipation area. At the same time, the sealing gasket 403 is used to seal around the light group 2 of the light strip 1 to reduce dust intrusion.

[0035] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
