Abstract: Electrodeless high intensity discharge lamps have the promise of higher reliability and higher efficiency than traditional electroded high intensity discharge lamps. However most electrodeless HIDs operate in the frequency range of around 400 MHz to 2.5 GHz resulting in expensive, inefficient RF drivers that reduce the overall efficacy of the lamp. Operating the lamp at lower frequencies results in substantial increase in the size of the resonators used in traditional electrodeless HIDs. In this invention a novel design is used to lower the operating frequency of the resonator without increasing the size of the resonator. This provides an avenue to increase the conversion efficiency of the RF driver and the efficacy of the lamp system.

Abstract: A dielectric barrier discharge lamp assembly for a fluid treatment system. The lamp assembly can include an inductive secondary, first and second electrodes coupled to the inductive secondary, and a lamp including a dielectric barrier interposed between the first and second electrodes. The dielectric barrier can define a discharge chamber including a discharge gas, and one of the first and second electrodes can extend within the discharge chamber. The inductive secondary can be adapted to receive power from a nearby inductive primary to promote a dielectric barrier discharge in the discharge chamber. The resulting dielectric barrier discharge can generate ultraviolet light for the treatment of air or water, or for other applications.

Abstract: A light source, with electrodes of alternating polarity attached to a substrate in an excimer ultraviolet (UV) lamp, for generating a plasma discharge between each of the electrodes. The shape of the substrate can shape and control the plasma discharge to reduce exposure of materials susceptible to attack by the halogens. The electrodes can be located such that the plasma discharge occurs in a region where it produces less contact of the halogens with the vulnerable areas of the lamp enclosure. The materials, such as the electrodes, substrate, and envelope, can be selected to withstand corrosive materials. In another embodiment, a plurality of sealed tubes, at least some of which contain an excimer gas are positioned between two electrodes.

Abstract: A method of forming a microplasma device places a curable polymer material between a mold having a negative volume impression of microcavities and/or microchannels and a substrate. The polymer is cured and then the mold is separated from the solid polymer. The method can form a microplasma device that includes a substrate and either or both of a microchannel or microcavity defined in a polymer layer supported by the substrate. Electrodes arranged with respect to the polymer material can excite plasma in a discharge medium contained in the microchannel or the microcavity or both. A flexible mold is preferably used to fabricate transparent polymer microcavities onto rigid substrates. A rigid mold is preferably used to fabricate transparent polymer microcavities onto flexible substrates. Having one of the mold and the substrate flexible and the other rigid aids in the separation of the mold from the cured polymer.
