Description

Technical Field

[0001] The utility model relates to the field of light strips, and in particular to a double-sided light strip that can be quickly attached. Background Art

[0002] The conventional process for double-sided light strips on the current market is to use two separate PCB light strips for back-to-back pasting. During the back-to-back pasting process, the two PCB boards are prone to relative displacement and are not easy to align completely, which requires a lot of labor, material and time costs during the pasting and alignment process. The pasting process generally uses solder paste or adhesive to stick the two PCB boards together, which will cause the adhesive to not stick firmly or cause a short circuit when the solder paste reflows.

[0003] In view of this, this application is filed. Utility Model Content

It only needs to set the shapes of the two sides of the PCB board during production. There is no need to spend manpower to align two separate PCB boards, and there will be no misalignment problem.

[0025] An arc-shaped folding ear 3 is provided in the middle of the PCB board 1, and the arc-shaped folding ear 3 can be bent toward the inner side of the arc, so that the left and right sides of the PCB board 1 can be bent and attached along the arc-shaped folding ear 3. The left and right sides refer to two parts that are symmetrically divided with the arc-shaped folding ear 3 as the center line.

[0026] The circuits arranged on the left and right sides of the PCB board 1 are connected through the arc-shaped folding ears 3, that is, there is a circuit bridge on the arc-shaped folding ears 3, which can play a role in circuit connection, and there is no need to attach additional circuits like two separate PCB boards back to back, thereby reducing the workload and improving the circuit stability. The structure of the arc-shaped folding ears 3 itself conforms to the bending characteristics, and the design of the arc-shaped bending part can effectively solve the problem that the circuit is easily broken after the existing PCB board 1 is folded.

At the same time, since the curved folding ear 3 itself is a part of the PCB board 1, it assists in fixing the two sides of the PCB board, and the requirements for adhesive are reduced. There is no need to worry about the problem of loose adhesion and easy detachment caused by using adhesives, and there is no need to worry about the circuit connectivity problem on both sides of the PCB board 1. After using a single PCB board 1 to emit light on both sides, its structural design is simpler, the process is easier to implement, and more production costs are reduced, so that the consumer market benefits more.

[0030] In this embodiment, the left and right sides of the PCB board 1 are symmetrically arranged along the arc-shaped folding ears, so that the PCB boards 1 can be completely aligned after being folded and pasted. In other embodiments, the shapes of the left and right sides of the PCB board 1 can be designed as needed.

[0031] Furthermore, in this embodiment, the circuit of the PCB board 1 and the lamp beads 2 arranged on the PCB board 1 are symmetrically arranged along the arc-shaped folding ears 3.
