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.

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.

Patent number: 6177678Abstract: A lamp system is for use in non-destructive testing to illuminate luminescent materials, such as fluorescent dyes. The lamp system has a control unit and a lamp. The lamp has a bulb and a filter. The bulb generates at least a first wavelength of invisible energy and the filter limits other visible wavelength light from the lamp. The lamp has a handle with a trigger. The control unit pulses the lamp on and off when the trigger is depressed. The lumiescent material absorbs the first wavelength of energy and pulses in response when the lamp illuminates the material. The system can be AC or DC operated. It can be operated from an automotive battery. A fault locating system for use with fluorescent dyes to detect faults in a body has a handheld D-type battery flashlight configuration with a casing having a handle at one end and a flared lamp housing at the other. A reflector fits within the lamp housing, and a bulb rests in the reflector.Type: GrantFiled: April 13, 1998Date of Patent: January 23, 2001Assignee: Brasscorp Ltd.Inventors: Jack Brass, Thomas M.

Patent number: 5730521Abstract: A luminaire especially suited for sports and roadway applications. The reflector of the luminaire has a modified parabolic shape wherein a true parabolic curve has been tipped inwardly to produce a tipped parabolic reflector having a circle of focal points centered on the focal point of the original true parabolic curve. The lamp comprises a double-ended arc lamp which is positioned transversely of the central axis of the reflector with the arc of the lamp generally tangent to top dead center of the focal point circle. The luminaire further includes a vertical black partition positioned within the reflector below and forwardly of the lamp and a specular insert in the upper front region of the reflector.Type: GrantFiled: May 13, 1996Date of Patent: March 24, 1998Assignee: International Sports Lighting, Inc.Inventors: Kenneth M.

Patent number: 5485319Abstract: A device for lighting a medical treatment field is disclosed and includes an optical member for focusing a plurality of light rays. The device also includes a prism assembly formed of a plurality of sectors of prisms. Each prism has an entry face and an exit face. The vertices of the sectors are substantially located in the center of the prism assembly. The sectors of prisms are configured and dimensioned so that the optical focusing member can focus the plurality of light rays generally onto the entry faces of the prisms. In addition, the device includes a mechanism for displacing at least a predetermined number of sectors such that the exit faces of the prisms of the predetermined sectors can be selectively positioned in one of a generally planar or a non-planar configuration. In an alternative embodiment, the device includes an optical focusing member and a prism assembly wherein the exit faces of the prisms are generally arc shaped along the length of the sector.Type: GrantFiled: March 17, 1993Date of Patent: January 16, 1996Assignee: Alm S.A.Inventor: Thomas M.

Patent number: 5390095Abstract: A visual signaling device which has a horizontally extending lamp which is connected to an electrical housing and which is surrounded by a reflector body. The reflector body has a pair of oppositely extending horizontal parabolic troughs and a downwardly extending horizontal trough. Each trough has an input opening adjacent the lamp, an output end opening, and a front opening. Each trough is defined by a generally planar back wall and a pair of opposed side walls. Each side wall is horizontal from the back wall to the front opening and parabolic relative to the central longitudinal axis of the lamp from the input opening to the output end opening. In a second embodiment of the invention, the reflector has an upwardly extending parabolic trough.Type: GrantFiled: March 29, 1994Date of Patent: February 14, 1995Assignee: Space Age Electronics, Inc.Inventors: Thomas M.

Patent number: 5313379Abstract: An asymmetric luminaire for illuminating large outdoor areas, such as an athletic field, wherein glare and light spillage is minimized and controlled. The luminaire includes a reflecting surface of a generally parabolic configuration, and an arc light source is located within the luminaire, the length of the light source being disposed at approximately 45.degree. with respect to the parabolic axis. A visor is used at the peripheral rim of the luminaire to control vertical and lateral light spillage, and the visor includes light source shields to prevent vertical spillage from the upper region of the luminaire. The luminaire reflecting surface includes a plurality of elliptical light reflecting ridges for restricting the near light beam height, and the upper portion of the reflecting surface can include substantially conical concentric light reflecting flute surfaces for accurately directing the light to target locations remote from the luminaire.Type: GrantFiled: March 11, 1993Date of Patent: May 17, 1994Assignee: Qualite Sports Lighting, Inc.Inventors: Thomas M.
