Abstract

A light source for use in examining leak detection sites in heating, ventilating, and air conditioning systems that utilize a fluorescence-producing dye in the refrigerant to determine the presence of leaks. The light source combines a dichroic reflector with a lamp and interference filter to provide a narrowed emission of wavelength of light emitted from the light source.
