▎ 摘　　要

NOVELTY - The lamp has a tungsten electrode rod whose end is winded with thorium-tungsten electrode wires. Oxidation barium electron emission layer is filled in a micro-gap that is formed between the thorium-tungsten electrode wires. The thorium-tungsten electrode wires and the oxidation barium electron emission agent are coated with a graphene thin film layer by using vacuum sealing process. Two ends of a ceramic electric arc pipe are fixed with a graphite alkene poker bar. The graphene thin film layer is coated on the tungsten electrode rod. USE - Graphene electrode ceramic metal halide lamp. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a graphene electrode ceramic metal halide lamp.
