Inductively coupled dielectric barrier discharge lamp
First Claim
1. A point-of-use water treatment system comprising:
- an inductive primary adapted to generate a time-varying electromagnetic field in a power supply mode and in a communications mode; and
a lamp assembly adapted to be removably supported within the water treatment system and adapted to radiate ultraviolet light for treating a fluid moving through the water treatment system, the lamp assembly including;
an ultraviolet lamp, an inductive secondary adapted to receive power from the inductive primary, and a memory associated with the ultraviolet lamp and contained within the lamp assembly,wherein the inductive secondary is adapted to receive power from the inductive primary when operating in the power supply mode and adapted to supply the power to the ultraviolet lamp, andwherein the inductive primary is operable in the communications mode to read historical lamp operation data from the memory before energizing the ultraviolet lamp, the historical lamp operation data relating to past operation of the lamp assembly, and operable in the communications mode to write to the memory to update the historical lamp operation data after energizing the ultraviolet 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.
