Led inspection lamp and led spot light
First Claim
1. An inspection lamp having light emitting diodes as a source of radiation suitable for causing visible fluorescence of fluorescent materials, where said light emitting diodes are substantially non-identical in spectral characteristics of their emitted radiation, such that at least one but not all of said light emitting diodes in said inspection lamp produce wavelengths of radiation that are favorable for causing visible fluorescence of some fluorescent materials, and such that one or more different said light emitting diodes in said inspection lamp produce substantially different wavelengths of radiation which are more favorable than the wavelengths of first said light emitting diode(s) for causing visible fluorescence of some fluorescent materials other than first said fluorescent materials, and wherein if one light emitting diode is emitting radiation then at least one other light emitting diode is emitting radiation.

Abstract
An LED inspection lamp has plurality of LED sources for emitting electromagnetic radiation at different peak wavelengths for causing visible fluorescence in different leak detection dyes. A lens is associated with each LED. Radiation passing through lenses is superimposed in target area at target distance. Another LED inspection lamp has plurality of LEDs emitting electromagnetic radiation at a peak wavelength. A lens adaptor has lens housing for attachment to LED inspection lamp with a single LED for causing visible fluorescence, and a lens. Substantially all of the radiation from the LED passes through the lens and is focused in a target area at a target distance from the lenses. LED spot lights have a similar configuration. The LEDs may produce white light from distinct LEDs or from white LEDs. The light may be a flashlight or fixed spot light.
