INDUCTIVELY COUPLED DIELECTRIC BARRIER DISCHARGE LAMP
First Claim
1. A lamp assembly comprising:
- an inductive secondary adapted to receive power from an inductive primary, the inductive secondary being separable from the inductive primary;
first and second electrodes electrically coupled to the inductive secondary, the first and second electrodes being spaced apart from each other; and
a lamp including a dielectric barrier interposed between the first and second electrodes, wherein the inductive secondary is adapted to receive power from the inductive primary and adapted to supply the power to the first and second electrodes to promote a dielectric barrier discharge in the lamp.

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.
