Abstract:
1. A plasma electrode-less lamp, comprising: an electromagnetic resonator; an electromagnetic radiation source conductively connected with the electromagnetic resonator; a first field probe conductively connected with the electromagnetic resonator; a second field probe conductively connected with the electromagnetic resonator; a gas-fill vessel with a closed, transparent body having an outer surface and an inner surface, the inner surface forming a cavity, the gas fill vessel detached from the electromagnetic resonator and capacitively coupled with the first field probe and the second field probe; and a fluorophor contained within the cavity of the gas-fill vessel, whereby the fluorophor fluoresces when electromagnetic radiation from the electromagnetic radiation source resonates inside the electromagnetic resonator, the electromagnetic resonator capacitively coupling the electromagnetic radiation to the fluorophor.
