Description

Technical Field

[0001] This utility model relates to the field of flexible LED light strip technology, and in particular to a flexible LED light strip structure with wavy lines. Background Technology

[0002] LED lights are common lighting devices in daily life. LED lights with flexible circuit boards, also known as LED strips, are made by soldering LEDs onto copper wires or flexible circuit boards using a special process, and then connecting them to a power source to emit light. They are named for their strip-like shape when they emit light, and can be used for decoration and lighting.

[0003] A search revealed that Chinese utility model patent CN202220469825.8 discloses an enhanced flexible LED light strip and its mounting structure. The strip includes a flexible circuit board and LED light emitters mounted on the flexible circuit board. The length direction of the LED light emitters is perpendicular to the length direction of the flexible circuit board. There are m groups of LED light emitters arranged along the length direction of the flexible circuit board and n groups arranged along the length direction perpendicular to the flexible circuit board. The n LED light emitters in the same group are connected in parallel and connected in series with the LED light emitters in adjacent groups. Here, m and n are natural numbers greater than 1. This design effectively solves the problem that flexible LED light strips are unsuitable for long-term bending with small arcs and effectively prevents other LED light emitters from working normally when one or a few LED light emitters malfunction.

[0004] For example, Chinese utility model patent application number CN202323208775.1 discloses a full-spectrum LED flexible light strip, which solves the problem of fixed light strip length and lack of sterilization function in the prior art. It includes a connecting box with two symmetrically arranged flexible strips. The two ends of the flexible strips are respectively fixedly connected to a left insertion block and a right insertion block. The connecting box has two symmetrically arranged limiting components inside. The limiting components include telescopic sleeves. The telescopic sleeves are rotatably installed inside the connecting box. The telescopic sleeves have a long telescopic rod and a short telescopic rod slidably assembled inside. One end of the short telescopic rod is movably hinged to an L-shaped lever. Through the setting of the L-shaped lever, the inclined block and other structures, the two flexible strips can be firmly connected together and are easy to disassemble, making it convenient for consumers to splice multiple flexible strips to the required total length.

[0005] While the existing flexible LED light strips can meet basic usage requirements, their circuit structure layout is relatively simple and linear, resulting in a lack of overall aesthetic appeal, limited application scenarios, and difficulty in meeting diverse user needs. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a flexible LED light strip structure with a wavy line, in order to address the above-mentioned defects of the existing technology, and solve the problems that the existing flexible LED light strips have a relatively simple structure, insufficient overall aesthetics, limited application scenarios, and difficulty in meeting the diverse needs of users.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] A flexible LED light strip structure with wavy lines includes a flexible circuit board body. The flexible circuit board body is provided with an upper welding line, a middle welding line and a lower welding line arranged sequentially from top to bottom. The upper welding line is welded with a plurality of first power input pads and a constant current IC chip. The middle welding line is welded with a plurality of LED beads. The lower welding line is welded with a plurality of second power input pads. The bottom of the upper welding line, the top of the lower welding line and the edge of the middle welding line are all arranged in a wavy shape.

[0009] Preferably, the first power input pad and the second power input pad are arranged longitudinally.

[0010] Preferably, the constant current IC chip and the LED beads are arranged vertically.

[0011] Preferably, a first wavy gap separates the intermediate welding line from the upper welding line, and a second wavy gap separates the intermediate welding line from the lower welding line.

[0012] Preferably, the constant current IC chip is electrically connected to the first power input pad, the second power input pad, and the LED beads, respectively.

[0013] Preferably, a first resistor is welded onto the intermediate welding line, and a second resistor is welded onto the lower welding line.

[0014] By adopting the above technical solution, the flexible LED light strip structure with wavy lines provided by this utility model has the following beneficial effects: The flexible circuit board body of the flexible LED light strip structure is provided with an upper welding line, a middle welding line and a lower welding line arranged sequentially from top to bottom. Several first power input pads and constant current IC chips are welded on the upper welding line, several LED beads are welded on the middle welding line, and several second power input pads are welded on the lower welding line. The bottom of the upper welding line, the top of the lower welding line and the edge of the middle welding line are all set in a wavy shape. By adopting a wavy structure design, the bottom of the upper welding line, the top of the lower welding line and the edge of the middle welding line are set in a wavy shape, which diversifies the structure, improves the aesthetics of the entire flexible LED light strip, increases the application scenarios of the flexible LED light strip, and can meet the diverse needs of users.
