WIRELESSLY POWERED DIELECTRIC BARRIER DISCHARGE LAMP, AND BASE STATION FOR A WIRELESSLY POWERED FLUID TREATMENT SYSTEM

摘要

A dielectric barrier discharge lamp assembly ( 20 ) is disclosed, e.g. for a fluid treatment system. The lamp assembly includes an inductive secondary ( 24 ), first and second electrodes ( 26, 28 ) coupled to the inductive secondary, and a lamp ( 30 ) including a dielectric barrier interposed between the first and second electrodes. The dielectric barrier defines a discharge chamber including a discharge gas. The inductive secondary is 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. Further, a base station for a fluid treatment system is disclosed, including an inductive primary ( 22 ), adapted to provide a source of wireless power to a lamp assembly including e.g. a dielectric barrier discharge lamp, a gas discharge lamp, an incandescent lamp, or a LED and having an inductive secondary. The base station further includes a driver circuit adapted to drive the inductive primary with a time-varying voltage which is controled based on a fluid charcteristic, and a fluid sensor adapted to detect said fluid characteristic.
