Patent ID: 7252763

Claim:
A lamp assembly for use in a water treatment system comprising: a housing having an inlet opening and an outlet opening; a bulb assembly disposed within the housing to produce radiation, the bulb assembly including a bulb having a bulb longitudinal axis; at least one conduit connecting the inlet opening and the outlet opening transporting fluid through the housing, the conduit including a conduit longitudinal axis that is substantially parallel to the bulb longitudinal axis; and a reflector assembly disposed within the housing, said reflector assembly including at least two diminishing radii of curvature that terminate at a terminal curvature peak which projects toward and immediately adjacent the bulb, wherein substantially all light emitted from the bulb assembly is reflected away from the bulb assembly toward the at least one conduit to treat water flowing therethrough, wherein each of the diminishing radii of curvature transition at locations opposite the terminal curvature peak to corresponding constant radii portions of the reflector assembly, wherein the conduit is positioned adjacent at least one of the constant radii portions.
