Abstract:
1. A plasma electrode-less lamp, comprising: (a) a gas-fill vessel comprising: (b) a gas-fill contained within the gas-fill vessel, the gas-fill comprising: (c) an RF electromagnetic radiation source comprising: (d) an RF electromagnetic resonator having a Q such that a substantial amount of RF power is coupled into the gas-fill, the RF electromagnetic resonator comprising: (e) an output probe conductively connected with the second conductive veneer of the gas-fill vessel, the output probe selected from the group consisting of e-field probe, h-field probe, and patch antenna, the output probe intersecting the output end substantially within the output opening, the size, shape, and position of the output probe creating substantial impedance matching between the RF electromagnetic resonator and the gas-fill vessel; (f) an input probe conductively connected with the RF amplifier output of the RF electromagnetic radiation source, the input probe selected from the group consisting of e-field probe, h-field probe, and patch antenna, the input probe intersecting the input end substantially within the input opening, the size, shape, and position of the input probe creating substantial impedance matching between the RF electromagnetic resonator and the RF electromagnetic radiation source; and (g) a grounding strap conductively connecting the first conductive veneer of the gas-fill vessel with the conductive veneer of the RF electromagnetic resonator; whereby RF electromagnetic radiation is coupled to the gas via the RF electromagnetic resonator, which forms a plasma that heats the fluorophor and thus causes the fluorophor to fluoresce.
