Inductively coupled dielectric barrier discharge lamp
First Claim
1. A fluid treatment system comprising:
- a base station defining a fluid flow path and including;
a water quality sensor adapted to provide an output based on a characteristic of water in the fluid flow path,a water flow rate sensor adapted to provide an output based on a flow rate of water in the fluid flow path,a primary coil adapted to generate a time-varying electromagnetic field and having a variable power output, anda controller adapted to control the power output of the primary coil based on the output of the water quality sensor and the output of the water flow rate sensor; and
a lamp assembly configured to be received within the base station and including a secondary coil that is inductively coupled to the primary coil, the lamp assembly being adapted to radiate ultraviolet light for treatment of water in the fluid flow path in response to the time-varying electromagnetic field generated by the primary coil, the ultraviolet light having an intensity based, at least in part, on the power output of the primary coil.

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.

11. A method of operating a lamp assembly, comprising:
-
providing a base station defining a fluid flow path and including a primary coil; providing a lamp assembly within the base station and including a secondary coil; measuring the flow rate of water in the fluid flow path; measuring the quality of water in the fluid flow path; selecting a power output of the primary coil based on the measured flow rate of water in the fluid flow path and based on the measured quality of water in the fluid flow path; and energizing the primary coil such that the primary coil provides the selected power output to the secondary coil to cause the lamp assembly to radiate ultraviolet light at a desired intensity for treatment of water in the fluid flow path. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
