Patent ID: 7544291

Claim:
A water purification system comprising: an inlet; an ultraviolet radiation chamber, the ultraviolet radiation chamber being made of a transparent material; and an outlet, wherein the inlet is connected in fluid relationship to the ultraviolet radiation chamber and the outlet is connected in fluid relationship to the ultraviolet radiation chamber to allow water to flow between the inlet and the outlet through the ultraviolet radiation chamber, wherein the ultraviolet radiation chamber has inner and outer surfaces, wherein water flowing through the ultraviolet radiation chamber is in contact with the inner surface thereof, wherein a plurality of ultraviolet light emitting diodes are molded directly into the outer surface of the ultraviolet radiation chamber making said light emitting diodes an integral part of the ultraviolet radiation chamber and wherein the plurality of ultraviolet light emitting diodes are electrically connected to a flexible electrical circuit board that at least partially surrounds the ultraviolet radiation chamber.
