[0002] LED backlight strips, also known as light-emitting diode light strips, refer to LEDs assembled on a strip-shaped FPC (flexible printed circuit board) or PCB rigid board. They are named for their strip-like shape. LED light strips can be divided into rigid LED light strips and flexible LED light strips.

[0003] A search revealed, for example, a utility model with publication number CN218298705U, which discloses an LED backlight strip with anti-wear function. The utility model discloses an LED backlight strip comprising a flexible strip with multiple LED beads disposed inside the front side, multiple equally spaced back holes fixedly connected to the back side, and multiple limiting posts fixedly connected to the center of the front side. LED backlight strips generate heat during operation, which accumulates over time. When the heat accumulates to a certain level, it can easily damage the LED backlight strip. However, this utility model does not facilitate heat dissipation during operation. Therefore, to address these shortcomings, the inventors propose an LED backlight strip with anti-wear function.

[0020] 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.

[0021] This utility model discloses an LED backlight strip with wear-resistant function, such as Figure 1-5 As shown, the backlight strip body 2 includes a mounting bracket 1 located on the rear side of the outer surface of the backlight strip body 2 and multiple LED lamp bodies 3 located on the front side of the outer surface of the backlight strip body 2. Mounting holes 101 are provided on both sides of the outer surface of the mounting bracket 1. A heat-conducting plate 102 is fixedly installed on one side of each mounting hole 101, and both heat-conducting plates 102 are in contact with the rear side of the outer surface of the backlight strip body 2. Multiple heat dissipation fins 103 are fixedly installed on one side of the outer surface of each heat-conducting plate 102, and the multiple heat dissipation fins 103 are respectively located inside the two mounting holes 101. The heat generated by the backlight strip body 2 during operation is transferred to the multiple heat dissipation fins 103 through the heat-conducting plate 102 for heat dissipation. Multiple heat dissipation pipes 201 are fixedly installed on both the upper and lower sides of the outer surface of the backlight strip body 2. The heat generated by the backlight strip body 2 during operation is also dissipated through the heat dissipation pipes 201 to reduce the heat inside the backlight strip body 2.

[0022] The outer surface of the heat pipe 201 is covered with a dust cover 202. The top surface of the dust cover 202 has multiple ventilation holes, which can effectively prevent external dust from entering the heat pipe 201 while hot air flows.

[0023] The dust cover 202 has connection holes 203 on both sides of its outer surface, and the heat dissipation pipe 201 has telescopic holes 204 on both sides of its outer surface. A first spring 205 is fixedly installed inside each of the two telescopic holes 204. A connector 206 is fixedly installed at one end of each of the two first springs 205 near the opening of the telescopic hole 204. The connector 206 is pushed into the telescopic hole 204 to compress the first spring 205. Then, the dust cover 202 is placed over the opening of the heat dissipation pipe 201 until it is fully installed. The compressed first spring 205 will then push the connector 206 to reset. Since the size of the connector 206 is the same as the size of the connection hole 203, the connector 206 can pass through the connection hole 203 to complete the installation of the dust cover 202, which facilitates the disassembly and cleaning of the dust cover 202.

[0024] The backlight strip body 2 has multiple mounting slots 302 on the front side of its outer surface. The mounting slots 302 are threaded with a protective cover 303, and the LED lamp body 3 is located inside the protective cover 303. The protective cover 303 is made of transparent plastic, which can protect the LED lamp body 3 while not blocking the light produced by the LED lamp body 3. The backlight strip body 2 is fixedly installed with an anti-corrosion sticker 301 to achieve the effect of preventing wear.

[0025] The mounting bracket 1 has a drive cavity 1011 on both the left and right inner sides. A second spring 1012 is fixedly installed on both sides of the drive cavity 1011. A connecting plate 1013 is fixedly installed on one end of the two second springs 1012 away from the opening of the drive cavity 1011. When the connecting plate 1013 moves toward the side of the opening of the drive cavity 1011, it will squeeze the second spring 1012.

[0026] A movable block 1014 is fixedly mounted on one side of the connecting plate 1013, located on the second spring 1012. A portion of the movable block 1014 is located inside the driving cavity 1011, while the other portion is located outside the driving cavity 1011. A fixed arm 1015 is fixedly mounted on one end of the movable block 1014 located outside the driving cavity 1011, and the backlight strip body 2 is located between the two fixed arms 1015. Pulling the fixed arms 1015 away from each other causes the movable block 1014 to move away from the connecting plate 1013. Move towards the opening of the drive cavity 1011 so that the connecting plate 1013 compresses the two second springs 1012. Then place the backlight strip body 2 between the two fixed arms 1015. After that, release the two fixed arms 1015. The compressed second springs 1012 will push the connecting plate 1013 and the movable block 1014 to reset, so that the two fixed arms 1015 can move closer to each other to clamp and fix the backlight strip body 2. Rubber pads are fixedly installed on the opposite ends of the two fixed arms 1015.

[0027] The working principle of this utility model is as follows: The mounting bracket 1 is installed on the external component by bolts, and then the fixed arms 1015 are pulled away from each other, so as to drive the movable block 1014 and the connecting plate 1013 to move towards the side of the opening of the drive cavity 1011, so that the connecting plate 1013 squeezes the two second springs 1012. Then the backlight strip body 2 is placed between the two fixed arms 1015. After that, the two fixed arms 1015 are released, and the squeezed second springs 1012 will push the connecting plate 1013 and the movable block 1014 to reset, so that the two fixed arms 1015 can move closer to each other to clamp and fix the backlight strip body 2. The heat generated by the backlight strip body 2 during operation will be transferred to multiple heat dissipation fins 103 through the heat conduction plate 102. The multiple heat dissipation fins 103 can dissipate heat, and the heat of the backlight strip body 2 will also be dissipated through multiple heat dissipation pipes 201 to reduce the heat of the backlight strip body 2, thereby dissipating heat during the operation of the backlight strip body 2.
