▎ 摘 要
NOVELTY - The bulb has a main tungsten filament attached with a graphene film layer. Two ends of the main tungsten filament are connected with metal wires of a lamp core column. The main tungsten filament is arranged in parallel with an auxiliary tungsten filament. The main tungsten filament and the auxiliary tungsten filament are sealed in the bulb shell. The bulb shell is arranged with the lamp core column. The bulb shell is bonded with a lamp head. A metal wall, a lamp metal contact and two spiral electrode wires are welded with the lamp core column. USE - Tungsten-based graphene bulb. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a tungsten-based graphene bulb.
