Patent number: 9599563Abstract: 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.Type: GrantFiled: July 15, 2009Date of Patent: March 21, 2017Inventors: Jack Brass, Richard J. Doran, Donald L. Klipstein, Thomas M. Lemons, Bjarki Hallgrimson, Sarah Dobbin

Publication number: 20040223342Abstract: LED inspection lamps and spot lights have a plurality of LED sources. For some, radiation passing through lenses is superimposed in target area at target distance. The LED sources may be a cluster LED having more than one semiconductor die. The LED package may have a domed forward surface forward of each semiconductor die for optical purposes. The domed surface may be designed to work either with or without additional optics. The LED package may be made of epoxy having additives to resist degradation of the epoxy by ultraviolet or visible violet radiation from the LED sources. The package may be made of a material other than epoxy, such as acrylic or another thermoplastic, or a casting resin. The package may have a first, ultraviolet-resistant material that surrounds the LED chip and that is surrounded by a second material which may be epoxy.Type: ApplicationFiled: May 28, 2004Publication date: November 11, 2004Inventors: Donald L.

Publication number: 20030123254Abstract: An LED inspection lamp has a plurality of LED sources, each source for emitting electromagnetic radiation at a different peak wavelength, each different peak wavelength for causing visible fluorescence in a different leak detection dye. A lens may be associated with each LED so that radiation passing through all lenses from their associated LEDs is superimposed in a target area at a target distance from the lenses. Another LED inspection lamp has a plurality of LEDs emitting electromagnetic radiation at a peak wavelength for causing visible fluorescence in a leak detection dye, and a lens associated with each LED so that the electromagnetic radiation passing through all lenses from their associated LEDs is superimposed in a target area at a target distance from the lenses.Type: ApplicationFiled: December 31, 2001Publication date: July 3, 2003Inventors: Jack Brass, Richard J.
