Abstract
The present invention is directed to a light monitoring system used in a water treatment system. The monitoring system includes a light pipe and a light intensity detector. The light pipe is impregenated with a florescent dye that converts ultraviolet light into visible light. The light pipe includes a plurality of internal facets that focus light incident on the light pipe toward the light intensity detector. The light intensity detector monitors the visible light transmitted to the detector by the light pipe and determines the relative ultraviolet light output intensity of a lamp assembly within the water treatment system based on the monitored visible light.
