Description

Technical Field

[0001] The utility model relates to the technical field of flexible LED light strips, in particular to a flexible LED light strip that is easy to produce. Background Art

[0002] LED lights are common lighting devices in daily life. LED lights with flexible circuit boards, also known as light strips, are made by soldering LED lights onto copper wire or a flexible circuit board using a special process. These lights are then connected to a power source to produce light. They are named for their strip-like shape when illuminated and can be used for both decorative and lighting purposes.

[0003] A search revealed a Chinese utility model patent application numbered CN202222104715.4, which discloses a flexible LED light strip comprising a flexible circuit board, several integrated packaged components, several current-limiting resistors, and several filter capacitors. The flexible circuit board is long and includes a functional area, which is located at the center of the flexible circuit board and arranged in a straight line along the length of the flexible circuit board. The integrated packaged components include an LED light-emitting chipset and an IC chip, which are integrated into a single device through an integrated packaging process. The integrated packaged components are soldered to the functional area. Signal transmission between the several integrated packaged components is connected in series and parallel. In this utility model, the signal transmission between the integrated packaged components is connected in series and parallel, transforming the signal transmission from single-channel to multi-channel, reducing the impact of a signal transmission failure in the previous integrated packaged component on the signal transmission of subsequent light strips.

The production process is relatively complicated, inconvenient to produce, and has high production costs. Utility Model Content
