Description

Technical Field

[0002] With the improvement of people's living standards, LED light strips have become a decorative lighting tool frequently used in people's lives. Most of the existing LED light strips generally achieve lighting by installing LED lamp beads on flexible circuit boards. The LED lamp beads will generate a lot of heat during operation. If they cannot be dissipated to the outside of the LED light strip in time, it will affect the stability and service life of the LED light strip lighting. However, the existing LED light strips do not have a structure to quickly guide the heat of the LED lamp beads, resulting in poor heat dissipation of the LED light strip, affecting the stability and service life of the LED light strip lighting. At the same time, because the LED light strips often need to be bent during installation, but the existing LED light strips do not have a structure to prevent the LED lamp beads from desoldering, the LED lamp beads and the flexible circuit board will be desoldered, resulting in poor consumer experience. Therefore, in order to avoid the shortcomings existing in the prior art, it is necessary to improve the prior art. Utility Model Content
