Abstract
Method and apparatus for generating UV and for treating a material with UV utilizing gas filled plasma-shells that emit UV during gas discharge. The UV treatment may include sterilization, purifying, or curing of liquids, gases, or solids. Applications include water treatment, chemical reactions, cosmetic tanning, and medical uses.
Claims20
A UV light-emitting device with a UV light-emitting source for purification of a selected fluid, the UV light-emitting source comprising a multiplicity of hollow shells filled with a gas that emits radiation during gas discharge, said shells being located on opposing sides of a substrate and encapsulating the gas independently of the substrate, said shells being made of a luminescent material that emits UV light when activated by radiation from the gas discharge, the gas discharge inside each plasma-shell being excited by a gas discharge voltage from conductors located on the substrate, said substrate and shells being in direct contact with the selected fluid for UV purification of the fluid.
A UV water purification device comprising a substrate with two opposing sides, a multiplicity of gas filled shells located on each opposing side, each shell connected to one or more conductors that provide a gas discharge voltage to each shell to produce UV light emission from each shell, said substrate and shells being in direct contact with the water for UV purification of the water.
