Abstract:
Described is a plasma electrode-less lamp. The device comprises an electromagnetic resonator and an electromagnetic radiation source conductively connected with the electromagnetic resonator. The device further comprises a pair of field probes, the field probes conductively connected with the electromagnetic resonator. A gas-fill vessel is formed from a closed, transparent body, forming a cavity. The gas-fill vessel is not contiguous with (detached from) the electromagnetic resonator and is capacitively coupled with the field probes. The gas-fill vessel further contains a gas within the cavity, whereby the gas is induced to emit light when electromagnetic radiation from the electromagnetic radiation source resonates inside the electromagnetic resonator, the electromagnetic resonator capacitively coupling the electromagnetic radiation to the gas, which becomes a plasma and emits light.
