▎ 摘　　要

NOVELTY - Manufacture of LED light bulb with graphene filament involves providing a flexible substrate which is printed circuit board (PCB), coating graphene-based heat dissipation ink on back side of the flexible PCB, cutting the coated PCB to form graphene filaments, and fixing the graphene filaments into a light bulb. USE - Manufacture of LED light bulb with graphene filament (claimed). ADVANTAGE - The method produces graphene filament-containing LED light bulb having improved life and excellent heat dissipation property (away from heat source) due to the presence of graphene coating.
