Technical Field

[0001] This utility model relates to the field of LED light strip technology, specifically a waterproof LED light strip. Background Technology

[0002] LED light strips are products in which LED light-emitting diodes are mounted on a strip of flexible printed circuit board (FPC) or rigid PCB. They are strip-shaped, have a long lifespan, are energy-saving and environmentally friendly, and have been widely used in various decorative industries. The advantage of LED light strips is that they can be cut to size according to needs, making installation and application more flexible.

[0003] LED light strips mainly consist of a circuit board and LED chips. The circuit board has printed circuitry. Depending on the manufacturing process, the LED chip leads can be soldered to the back of the circuit board, or the LED chips can be packaged on the front of the circuit board, allowing the LED chips to connect to the printed circuitry on the circuit board. Leads are soldered to the ends of the light strip for power connection. Current LED light strips are mass-produced using automated soldering, resulting in exposed solder joints on the leads. These solder joints have low tensile strength, lack protection, and are difficult to meet waterproof testing standards.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a waterproof LED light strip that is structurally sound, highly safe, and easy to assemble.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The present invention discloses a waterproof LED light strip, comprising a base strip and lead wires. A plurality of LED beads are arranged sequentially at intervals along the length of the base strip. The lead wires are soldered onto the base strip to form solder joints. A waterproof structure is fitted onto the base strip and lead wires, thereby sealing the solder joints.

[0008] According to the above scheme, the waterproof structure includes a rubber sleeve that surrounds the baseband and lead wire to tightly cover the baseband and lead wire.

[0009] According to the above scheme, the material of the adhesive sleeve is thermoplastic film, and the adhesive sleeve is applied to the baseband and lead wires through a thermoplastic process.

[0010] According to the above scheme, the baseband is provided with a sealing ring, which is sleeved on the baseband between the solder joint and the LED bead, and the sealing ring is covered by a rubber sleeve.

[0011] According to the above scheme, limit notches are opened on both sides of the baseband, and the sealing ring surrounds the baseband and is snapped onto the limit notches.

[0012] According to the above scheme, waterproof adhesive is applied between the rubber sleeve and the baseband, and between the rubber sleeve and the lead wire.

[0013] According to the above scheme, the waterproof structure also includes a sealing sleeve, with the rubber sleeve covering the first end of the base tape and the sealing sleeve covering the second end of the base tape.

[0014] According to the above scheme, the sealing sleeve is made of thermoplastic sleeve, and a sealing ring is also provided between the thermoplastic sleeve and the base tape.

[0015] The beneficial effects of this utility model are as follows: This utility model has a reasonable structure.

[0019] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 As shown, the waterproof LED light strip of this utility model includes a base strip 1 and lead wires 11. A plurality of LED beads 12 are arranged at intervals along the length of the base strip 1. The lead wires 11 are soldered to the base strip 1 to form solder joints 13. A waterproof structure is fitted onto the base strip 1 and the lead wires 11, covering the base strip 1 and the lead wires 11 to seal the solder joints 13. It can be understood that the waterproof structure is made of a flexible material, allowing it to fit and cover the surface of the base strip 1, achieving a tight seal of the solder joints 13. Furthermore, the waterproof structure also wraps around the lead wires 11, increasing the connection between the lead wires 11 and the base strip 1, thereby improving the tensile strength of the solder joints 13 and enhancing the stability, waterproofness, and service life of the light strip.

[0021] Specifically, the waterproof structure includes a rubber sleeve 2, which surrounds the baseband 1 and the lead wire 11 to tightly cover them. Preferably, the waterproof structure uses the rubber sleeve 2, which is elastic and can be fitted onto the baseband 1. The rubber sleeve 2, based on the shrinkability of its material, tightly conforms to the surface of the baseband 1. In particular, the rubber sleeve 2's contact with and coverage of the baseband 1 and the lead wire 11 generates friction, thereby increasing the connection strength between the lead wire 11 and the baseband 1, and consequently increasing the tensile strength of the solder joint 13.

[0022] Furthermore, the sleeve 2 is made of thermoplastic film, and the sleeve 2 is applied to the baseband 1 and the lead wire 11 using a thermoplastic process. The thermoplastic film is flexible at room temperature and can be easily fitted onto the baseband 1.

[0023] Furthermore, heating the sleeve 2 with hot air causes it to shrink and conform to the surfaces of the baseband 1 and the lead wire 11, thereby covering the baseband 1 and the lead wire 11 to achieve a sealed connection of the solder joint 13. Under normal conditions, the sleeve 2 is convex in shape. The larger end of the sleeve 2 can be inserted into the baseband 1 first, and the smaller end of the sleeve 2 can be fitted onto the lead wire 11. Then, under the action of hot air, it respectively covers and connects the baseband 1 and the lead wire 11.

[0024] Furthermore, from the appendix Figure 1 As can be seen, two leads 11, one live and one zero, are welded onto the baseband 1. The two leads 11 are spaced apart based on the welding spacing. The sleeve 2 can cover and connect the two leads 11 respectively, thereby further improving the tensile strength.

[0025] A sealing ring 21 is provided on the baseband 1. The sealing ring 21 is sleeved on the baseband 1 between the solder joint 13 and the LED bead 12, and the sealing ring 2 is covered by a rubber sleeve 2. Preferably, after the sealing ring 21 is sleeved on the baseband 1 and covered by the rubber sleeve 2, the sealing performance at the solder joint 13 can be effectively improved. In particular, the sealing ring 21 is snapped onto the limiting notch 14. After the rubber sleeve 2 shrinks, it can fit against the sealing ring 21. Of course, it will also form a flange under the support of the sealing ring 21. This flange will also limit the rubber sleeve 2 in the length direction of the baseband 1, preventing the rubber sleeve 2 from sliding, thereby improving the tensile strength.

[0026] Limiting notches 14 are provided on both sides of the baseband 1, and the sealing ring 21 surrounds the baseband 1 and is snapped onto the limiting notches 14. The limiting notches 14 can limit the sealing ring 21 and prevent the thermoplastic film sleeve 2 from shifting during the shrinkage process. Of course, the sealing ring 21 is also flexible. During the shrinkage process of the thermoplastic film sleeve 2, the sealing ring 21 is compressed, thereby improving the sealing performance.

[0027] As is known, the LED beads 12 on the baseband 1 emit light and generate heat, which can enhance the shrinkage of the thermoplastic sealing film sleeve 2, thereby further enhancing the sealing performance.

[0028] Waterproof adhesive is applied between the rubber sleeve 2 and the base band 1, and between the rubber sleeve 2 and the lead wire 11. The waterproof adhesive can also be a modifier, which can be used to improve the tightness of the bond between the rubber sleeve 2 and the base band 1. Of course, in addition to the above-mentioned sealing effect, the waterproof adhesive can also improve the tensile strength through bonding.

[0029] The waterproof structure also includes a sealing sleeve 3. A rubber sleeve 2 covers the first end of the baseband 1, and the sealing sleeve 3 covers the second end of the baseband 1. The sealing sleeve 3 is made of thermoplastic, and a sealing ring 21 is also provided between the thermoplastic sleeve and the baseband 1. The non-connection terminals of the baseband 1 are sealed with the sealing sleeve 3 to prevent water seepage and cracking of the circuit board baseband 1, thus preventing malfunctions. It is understood that the surface and / or back of the baseband 1 are coated with an insulating layer.

[0030] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
