[0002] LED light strip refers to LEDs assembled on a strip-shaped FPC (flexible circuit board) or PCB hard board. It is named because its product shape resembles a strip. It is gradually used in various industries due to its long service life, energy saving and green environmental protection. In order to facilitate lighting in humid places such as wardrobes and fish tanks, corresponding light strips are also used. However, due to the LED light strips themselves, they are easily affected by moisture, mildew, or attract mosquitoes, etc., which will cause the substrate of the LED light strips to be corroded and damaged, thereby affecting the service life of the LED light strips, so the applicability and practicality are limited. Summary of the invention

In this embodiment, in actual application, the intermediate PET film layer 23 includes a third PET film layer 231 and a fourth PET film layer 232 that are bonded and fixed to each other; The copper film layer is located between the first PET film layer and the third PET film layer, and the graphene layer is located between the fourth PET film layer and the second PET film layer. With the above structure, the copper film layer and the graphene layer are isolated by the middle PET film layer, so that the graphene layer will not affect the normal lighting of the lamp bead. At the same time, when the humidity of the environment reaches a certain value, the graphene layer will automatically generate heat, thereby achieving moisture-proof, mildew-proof, sterilization and insect repellent properties.

In actual application, the copper film layer and the graphene layer have the same thickness and the same width, and the width of the two can be the same as the first PET film layer or slightly smaller. In actual application, the lamp beads are single-color lamp beads or multi-color lamp beads.
