Abstract:
1. An inspection lamp, comprising: a) a plurality of substantially identical light emitting diodes which produce electromagnetic radiation suitable for causing visible fluorescence of a leak detection dye, b) a plurality of lenses, c) a handle section, d) a head section having an opening at one end, and e) a battery energy source in the handle, wherein the plurality of light emitting diodes are within the head section and powered by the battery energy source, wherein the plurality of lenses are within the head section, wherein the head section and handle section are physically connected in a flashlight configuration, and wherein each of said lenses forms a beam of said electromagnetic radiation, with each of said lenses being associated with one of said light emitting diodes in a manner that results in said beams being substantially superimposed with each other at a target distance from the lenses outside the lamp wherein each lens of the plurality of lenses is disposed forward from corresponding one of said light emitting diodes to collimate the radiation from each light emitting diode into a beam, such that each beam of radiation individually associated with each of said light emitting diodes projects forward from its lens and a plurality of beams of radiation simultaneously produced by a plurality of the light emitting diodes are at least substantially superimposed at a distance equal to or greater than 6 inches (15.24 centimeters) from the lenses.
