Title: Plasma lighting system with a metallic material in the bulb

Abstract: A plasma lighting system includes a magnetron configured to generate microwaves, and a bulb in which a dose for generation of light using the microwaves and at least one metallic material for generation of thermal electrons are received. The metallic material reduces an electric field intensity required for electric discharge by discharging thermal electrons. In this way, the plasma lighting system reduces the time it takes to turn the light back on after the light is turned off.
