Why does LED high-power lamp beads generate static electricity?

The reason why LED high-power beads are called LED high-power beads is because compared to low-power beads, LED high-power beads have higher and brighter power. The rated current of low-power LED beads is 20mA, and those with a rated current higher than 20mA can basically be considered high-power. I don‘t know if you have noticed that LED high-power lamp beads occasionally generate static electricity. Why is this?
There are several possible reasons for static electricity generated by high-power LED lamp beads:
1. Conduction: For conductive materials, charge transfer occurs when electrons can freely flow on their surface and come into contact with charged objects.
2. Induction: For conductive materials, due to the free flow of electrons on their surface, if placed in an electric field, due to the repulsion of the same species and the attraction of the opposite, positive and negative ions will transfer and generate charges on their surface.
3. Friction: In daily life, any two objects of different materials that come into contact and then separate can generate static electricity, and the most common method of generating static electricity is friction. The better the insulation of the material, the easier it is to generate electricity due to friction. In addition, any two different substances that come into contact and then separate can also generate static electricity.
