1. A light source for examination of a substance which reemits light at a wavelength greater than the wavelength of light emitted from said light source, said light source comprising:
- a lamp assembly including;
a faceted white light reflector;
said faceted white light reflector is a focusing reflector;
a lamp positioned between said faceted white light reflector and said substance;
said lamp connected to a source of electrical power and operated in response to said electrical power to emit light;
said faceted white light reflector functioning to reflect a selected portion of said light emitted from said lamp;
a lens filter positioned between said lamp assembly and said substance;
said lens filter operated to further restrict said light from said lamp and said light reflected by said faceted white light reflector;
whereby said light emitted from said light source is restricted to a predetermined range effective to enhance the reemission of light from said substance.

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 faceted reflector with a lamp and interference filter to provide a narrowed emission of wavelength of light emitted from the light source.
