The present invention provides a bulb (100, 110, 120, 130, 140, 140′) an excitation chamber (200, 210, 220, 230, 230′) a ferrite core (300, 310, 310′), a spool (400, 410); an assembly or subassembly of such components, and a lamp (100, 1100, 1200, 1300, 1400, 1500, 1600, 1600′, 1600″, 1700, 1800) for producing electromagnetic radiation, such as in the light spectrum, UV or IR.

A sanitization apparatus includes an excimer lamp and a power converter. The power converter comprises a wide band gap device and a planar inductor. The wide band gap device is selectively switchable between a first mode wherein the inductor is electrically charged and a second mode wherein the inductor is electrically discharged. The wide band gap may be repeatedly switched between the first and second modes to generate a nano second pulse output voltage waveform.

An RF fluorescent lamp, comprising a bulbous vitreous portion of the RF fluorescent lamp comprising a vitreous envelope filled with a working gas mixture, a power coupler to induce an alternating electric field within the vitreous envelope, an electronic ballast, and a mercury amalgam accommodating structure mounted within the lamp envelope and adapted to absorb power from the electric field to rapidly heat and vaporize an amalgam of mercury to rapidly illuminate the lamp envelope during a turn-on phase of the RF fluorescent lamp, wherein the structure is comprised of a substrate material coated with a mixture of indium and gold.

A closed loop tubular discharge assembly for an electrodeless light-emitting device and discharge reactor is disclosed. The discharge assembly comprises one or more tubular segments tubularly connected at their respective ends to form the closed loop tubular assembly, which hermetically encloses an ionizable gas. At least one of the one or more tubular segments forms a non-cylindrical, hollow-shaped tubular segment. In one embodiment, the non-cylindrical, hollow-shaped segment is formed by an internal tube at least partially enclosed within an external tube, forming a hollow-shaped discharge envelope enclosing the ionizable gas there between. When a discharge current circulates in the ionizable gas of the envelope, a hollow-shaped plasma is created in the envelope and surrounds the internal tube. This design has been shown to increase performance and provide several improvements over prior art devices.
