Description

Technical Field

[0001] The utility model relates to the technical field of neon light strips, in particular to a 3D-bendable neon light strip. Background Art

[0002] Neon light strips are a type of flexible decorative lighting fixture. The working principle of neon light strips is mainly based on the semiconductor luminescence characteristics of LED lamp beads. When current passes through the LED lamp beads, the electrons and holes in the semiconductor material recombine and release energy. This energy is emitted as light in the form of photons. By controlling the size and direction of the current flowing through the LED lamp beads, the brightness and color of the lamp beads can be adjusted.

[0003] Existing neon light strips are generally bent vertically or horizontally when in use. Since some neon lights are long and are not made of hard materials, they are particularly prone to bending in various shapes during installation, which can easily cause the PCB circuit board to break and cause damage. The practicality is insufficient and needs to be improved. Utility Model Content

[0023] The embodiment of the present application effectively solves the technical problem of insufficient practicality of existing neon light strips by providing a 3D bendable neon light strip.

[0024] Example

[0025] like Figure 1 - Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem of insufficient practicality of existing neon light strips. The overall idea is as follows:

[0026] In view of the problems existing in the prior art, the present invention provides a 3D-bendable neon light strip, comprising a U-shaped member 11 with a cavity left inside the U-shaped member 11;

[0027] A curved structure is placed inside the cavity of the U-shaped member 11;

[0028] The curved structure includes a PCB soft board 12, a soft board folding part 15 is symmetrically provided on the side wall of the PCB soft board 12, and a silicone layer 16 is symmetrically provided on the side wall of the U-shaped part 11. The curved structure also includes LED lamp beads 13, a power supply unit 14, PU glue 17 and a plug 18. Each LED lamp bead 13 is located at the upper end of the PCB soft board 12, and each LED lamp bead 13 is fixedly installed with the PCB soft board 12. By optimizing the structure and layout of the device, the PCB soft board 12 and the LED lamp beads 13 are placed inside the U-shaped part 11, and the PU glue 17 is poured inside the U-shaped part 11, so that physical contact can be achieved, thereby achieving an effective waterproof effect, and achieving full waterproof IP68, thereby improving practicality.

[0029] The two power supply units 14 are both located on both sides of the PCB soft board 12, and the two power supply units 14 are both fixedly installed with the PCB soft board 12. The PU glue 17 is located on the inner side of the U-shaped part 11, and the PU glue 17 is adapted to the PCB soft board 12 and the power supply unit 14. By using the PU glue 17 to pour and solidify the PCB soft board 12, the neon light strip not only has strong toughness, but can also be bent from side to side. At the same time, making full use of the toughness of the PU glue 17 can avoid the stress generated when the FPC of the PCB soft board 12 is bent, which may cause damage to the PCB soft board 12, thereby further improving practicality.

[0030] The two plugs 18 are both located on both sides of the U-shaped part 11, and the two plugs 18 are partially located inside the U-shaped part 11. The two plugs 18 are fixed to the U-shaped part 11. The inside of the two plugs 18 is hollow, and the PCB soft board 12 is partially located inside the plugs 18. By arranging the plugs 18 on both sides of the U-shaped part 11, the glue will automatically flow into the gap between the U-shaped part 11 and the plugs 18 when it is poured and solidified, thereby achieving IP68 waterproofing between the plugs 18 and the U-shaped part 11, which has high protection.

[0031] Working principle: During installation, the staff can first weld the FPC substrate of the PCB soft board 12 into a corresponding whole strip according to the process requirements, and then perform wire welding. After welding, the staff can then fold the power supply unit 14 on the inside of the U-shaped part 11 and squeeze it out of the bottom of the U-shaped groove. Then the staff can clamp the plug 18 on both sides of the U-shaped part 11, and then start glue filling, and finally let it stand until the glue is formed.

[0032] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
