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.
Claims16
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.
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 reflecting light primarily in an emission range having a wavelength between 400 and 700 nanometers;
- said faceted white light reflector is a focusing reflector;
- a lamp positioned between said faceted reflector and said substance;
- said 1amp connected to a source of electric power and operated in response to said electrical power to emit light;
- said faceted reflector functioning to reflect a selected portion of said light emitted from said lamp;
- whereby said light emitted from said light source is restricted to a predetermined range effective to enhance the reemission of light from said substance.
A light source for examination of a substance which reemits light at a wavelength greater than the wavelength of light emitted form light source, said light source comprising:
- a lamp assembly including;
- a faceted white light reflector reflecting light primarily in an emission range having a wavelength of between 325 and 700 nanometers;
- said faceted reflector is a focusing reflector;
- a lamp positioned between said faceted 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 reflector functioning to reflect a selected portion of said light emitted from said lamp;
- whereby said light emitted from said light source is restricted to a predetermined range effective to enhance the reemission of light form said substance.
