Description
Technical Field
[0001] This utility model belongs to the field of LED light strip technology, specifically relating to a threaded fastening type LED light strip. Background Technology
[0002] LED light strips are LEDs assembled on a strip-shaped FPC (flexible printed circuit board) or PCB (rigid PCB). They are named for their strip-like shape. Due to their long lifespan (typically 80,000 to 100,000 hours), energy efficiency, and environmental friendliness, they are gradually gaining popularity in various decorative industries. In current technology, each LED light strip has self-adhesive 3M double-sided tape on the back. During installation, the sticker on the 3M double-sided tape can be peeled off directly, and the light strip can be fixed to the desired location. However, using 3M tape for fixing will cause the adhesive strength to decrease over time, leading to the LED light strip falling off. Furthermore, using double-sided tape for fixing makes it difficult to dissipate heat from the back of the light strip, thus affecting stable operation. Utility Model Content
[0003] To overcome the problem that the use of 3M double-sided tape during LED strip installation can lead to a decrease in adhesive strength over time, causing the LED strip to fall off, and to address the issue that the use of double-sided tape can result in poor heat dissipation on the back of the strip, thus affecting stable operation.

[0005] Preferably, by using studs to fix the LED strip assembly to the heat dissipation assembly through the floodlight protection assembly, during operation, the heat is transferred to the heat dissipation assembly through the heat conduction component on the LED strip assembly, thereby achieving rapid heat dissipation. This solves the problem that the adhesion of 3M double-sided tape will decrease over time, causing the LED strip to fall off, and that the use of double-sided tape will lead to poor heat dissipation on the back of the LED strip, thus affecting stable operation.
[0006] Preferably, the light strip assembly includes a flexible circuit board, conductive sheets, a first groove, and LED beads; the upper end of the flexible circuit board has evenly distributed conductive sheets; the left and right ends of the flexible circuit board have first grooves; the upper end of the flexible circuit board has two LED beads; multiple flexible circuit boards are provided, and when the light strip needs to be cut, the connected flexible circuit boards can be cut along the left and right edges of the flexible circuit boards. The light strip can be made to work by inserting the conductive sheets into the power adapter.
[0007] Preferably, the floodlight protection component includes a transparent shell, stud mounting half-grooves, through grooves, and stud mounting slots; the transparent shell is movably disposed on the upper end of the flexible circuit board; through grooves are formed through both ends of the transparent shell; stud mounting half-grooves are formed through both ends of the transparent shell; two stud mounting slots are formed through the upper end of the transparent shell; the stud mounting half-grooves are half the shape of the stud mounting slots. By placing the transparent shell above the flexible circuit board, the light from the LED chips can be diffused more softly when the LED strip is working, and the through grooves can effectively dissipate heat from the LED chips during operation.
[0008] Preferably, the floodlight protection component includes a first placement slot and a second placement slot; the lower end of the transparent shell has a uniformly distributed first placement slot and a second placement slot; the first placement slot is adapted to the LED chip; the second placement slot is adapted to the conductive sheet, and the first placement slot is adapted to the LED chip; the LED chip can be protected after subsequent fixing.
[0009] Preferably, the heat-conducting component includes a heat-conducting sheet and a heat-conducting copper pipe; the heat-conducting sheet is fixedly connected to the lower end of the flexible circuit board; the heat-conducting copper pipe is fixedly connected to the lower end of the heat-conducting sheet, and the heat generated by the flexible circuit board during operation can be transferred to the heat-conducting copper pipe through the heat-conducting sheet; the heat-conducting sheet can prevent the lower end of the flexible circuit board from being directly connected to the heat-conducting copper pipe, which could cause a short circuit.
[0010] Preferably, the heat dissipation component includes a heat sink, ventilation slots, and threaded mounting slots; the heat sink is movably mounted on the lower end of the heat-conducting copper pipe; the upper end of the heat sink is in contact with the lower end of the heat-conducting copper pipe; the lower end of the heat sink has evenly distributed ventilation slots; the upper end of the heat sink has two threaded mounting slots extending through it; the radius of the threaded mounting slots is the same as the radius of the first slot; the heat-conducting copper pipe transfers heat from the flexible circuit board to the heat sink, and the heat sink dissipates heat through the evenly distributed ventilation slots at its lower end.
[0011] Preferably, the heat dissipation assembly includes a fixing stud; the fixing stud passes through the stud mounting groove and the first groove body in sequence and is threaded onto the inner wall of the threaded mounting groove. By using the fixing stud, the transparent shell and the flexible circuit board can be threaded onto the heat sink, which facilitates subsequent disassembly, maintenance and replacement.
[0012] The beneficial effects of this utility model are:
[0013] 1. By using fixing studs, the transparent shell and flexible circuit board can be threaded onto the heat sink, which facilitates subsequent disassembly, maintenance and replacement. This solves the problem that the LED strip will fall off due to the reduced adhesive strength of 3M double-sided tape over time.
[0014] 2. By placing the transparent shell on top of the flexible circuit board, the light from the LED beads can be diffused more softly when the light strip is working. The through groove can effectively dissipate heat from the LED beads when they are working. The heat-conducting sheet can transfer the heat generated by the flexible circuit board during operation to the heat-conducting copper pipe. The heat-conducting sheet can also prevent the lower end of the flexible circuit board from directly connecting to the heat-conducting copper pipe, which could cause a short circuit.
[0015] 3. The flexible circuit board can be cut along the left and right edges of the flexible circuit board. The light strip can be made to work by inserting the conductive sheet into the power adapter. Attached Figure Description

[0023] Please see Figure 2-3 In this embodiment, the light strip assembly 1 includes a flexible circuit board 101, conductive sheets 102, a first groove 103, and LED beads 104; the upper end of the flexible circuit board 101 has evenly distributed conductive sheets 102; the left and right ends of the flexible circuit board 101 have first grooves 103; the upper end of the flexible circuit board 101 is provided with two LED beads 104; multiple flexible circuit boards 101 are provided. The floodlight protection assembly 2 includes a transparent shell 201, stud mounting half-grooves 202, through grooves 203, and stud mounting slots 204; the transparent shell 201 is movably disposed at the upper end of the flexible circuit board 101; through grooves 203 are provided through the left and right ends of the transparent shell 201; stud mounting half-grooves 202 are provided at the left and right ends of the transparent shell 201; two stud mounting slots 204 are provided through the upper end of the transparent shell 201; the stud mounting half-grooves 202 are half the shape of the stud mounting slots 204. The heat dissipation assembly 4 includes a first placement slot 205 and a second placement slot 206; the lower end of the transparent shell 201 has a uniformly distributed first placement slot 205 and second placement slot 206; the first placement slot 205 is adapted to the LED bead 104; the second placement slot 206 is adapted to the conductive sheet 102. The heat dissipation assembly 4 includes a heat dissipation block 401, a ventilation slot 402 and a threaded mounting slot 403; the lower end of the heat-conducting copper pipe 302 is movably provided with a heat dissipation block 401; the upper end of the heat dissipation block 401 is attached to the lower end of the heat-conducting copper pipe 302; the lower end of the heat dissipation block 401 has a uniformly distributed ventilation slot 402; the upper end of the heat dissipation block 401 has two threaded mounting slots 403 extending through it; the radius of the threaded mounting slot 403 is the same as the radius of the first groove 103. The heat dissipation assembly 4 includes a fixing stud 404; the fixing stud 404 passes through the stud mounting slot 204 and the first groove 103 in sequence and is threaded onto the inner wall of the threaded mounting slot 403.
[0024] Please see Figure 4 In this embodiment, the heat-conducting component 3 includes a heat-conducting sheet 301 and a heat-conducting copper pipe 302; the lower end of the flexible circuit board 101 is fixedly connected to the heat-conducting sheet 301; the lower end of the heat-conducting sheet 301 is fixedly connected to the heat-conducting copper pipe 302.
[0025] When the light strip needs to be cut, the flexible circuit board 101 connected together can be cut along the left and right edges of the flexible circuit board 101.

During operation, the heat is transferred to the heat dissipation assembly 4 through the heat conduction assembly 3 on the LED strip assembly 1 for rapid heat dissipation. This solves the problem that the adhesion of 3M double-sided tape will decrease over time, causing the LED strip to fall off. In addition, the use of double-sided tape will lead to poor heat dissipation on the back of the LED strip, thus affecting stable operation.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
