Description

Technical Field

[0002] LED filaments are also called LED lamp posts. LED filaments can emit light at 360°. They can emit light at large angles without adding lenses, realizing a three-dimensional light source and bringing an unprecedented lighting experience. LED filaments are divided into rigid filaments and flexible filaments. Flexible filaments generally use copper foil laminated with polymer film as the substrate material, and several LED chips are fixed on the substrate, and finally the fluorescent glue is cured. Flexible filaments are relatively soft and plastic, and can be wound into various shapes like tungsten filaments. They are currently being used more and more in public places.
