A method of making a graphene LED bulb contains steps of: providing a glass substrate or other flexible substrate; sputtering and plating copper material on the glass substrate or other flexible substrate; coating photo resist, drying, and wet etching the substrate on which the copper material is plated; forming a printed circuit board (PCB) on the substrate; forming a graphene layer on the substrate or other flexible substrate by using a CVD (chemical vapor deposition) machine; bonding a flip chip on the substrate; molding or spraying a phosphor layer on the flip chip; laser cutting the substrate to form a graphene LED filament; and fixing the graphene LED filaments either rigid or flexible into a light bulb. |
