LIGHT SOURCE FOR USE IN LEAK DETECTION IN HEATING, VENTILATING, AND AIR CONDITIONING SYSTEMS THAT UTILIZE ENVIRONMENTALLY-SAFE MATERIALS

摘要

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.
