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.
Claims14
A plasma lighting system comprising:
- a magnetron configured to generate microwaves;
- and
- a bulb configured to emit light, the bulb including:
- a dose located in the bulb for generation of light under the influence of the microwaves;
- and
- at least one metallic material located in the bulb to reduce an electric field intensity required for electric discharge by discharging thermal electrons,
- wherein the metallic material is surrounded by an insulation capsule formed of ceramic and sealed in a vacuum state within the insulation capsule to prevent the metallic material and the dose from reacting.
