  • Patent number: 10401012
    Abstract: A high-intensity light source is formed by a micro array of a semiconductor light source such as a LEDs, laser diodes, or VCSEL placed densely on a liquid or gas cooled thermally conductive substrate. The semiconductor devices are typically attached by a joining process to electrically conductive patterns on the substrate, and driven by a microprocessor controlled power supply. An optic element is placed over the micro array to achieve improved directionality, intensity, and/or spectral purity of the output beam. The light module may be used for such processes as, for example, fluorescence, inspection and measurement, photopolymerzation, ionization, sterilization, debris removal, and other photochemical processes.

  • Patent number: 9482395
    Abstract: An LED luminaire includes a thermal management system and features minimal glare while allowing for use of traditional luminaire housing. The luminaire of the depicted embodiments includes a luminaire housing, an LED light module, an LED driver, a diffuser, and reflectors. The LED light module includes at least one LED array, a primary thermal interface, and a secondary thermal interface. These thermal interfaces, particularly when used in conjunction with a conductive housing, allow for optimal thermal management by utilizing both natural convection and conduction to remove the heat from inside the luminaire into the surrounding air. Additionally, in certain embodiments, the position of the LED arrays within the housing in combination with the reflector design creates an optical path resulting in an indirect light source that minimizes glare, while providing a uniform distribution of light, unlike traditional LED luminaires.

    Abstract: A material cutting system for trimming sheet material having a base, a blade engageable with the sheet material along a cut line and a material guide including an illuminated surface indicative of the location of the cut line. In one set of embodiments, an illuminating assembly produces light that is internally transmitted through a light guide portion of the material guide to the illuminated surface. The illuminated surface provides for ready and correct orientation of the sheet material to the desired position for cutting by the material trimmer.

  • Patent number: 8256921
    Abstract: An apparatus, system and method for lighting an area, for example, an outdoors pedestrian area or building facade or an auto traffic area, or an indoor large area, which provides indicator/guide light, reference light for structures, and task lighting for a target area. The method uses first lighting sources that are directly viewable by observers and which can be historical, architectural, or aesthetically selected sources, but which produce a relatively low level of light or luminance insufficient to effectively light the area but sufficient to act as an indicator or guide, as well as to provide reference illumination on buildings or structures. Second lighting sources are configured to produce directional light to light the area but hide the light sources from most conventional observer viewing angles and may be enclosed within the general outlines of the globe or transmissive surface area of the fixture.

  • Publication number: 20120180180
    Abstract: A method, means, apparatus, and system is disclosed, for use with an electrically controllable light-producing activity, or possibly an electrically-controlled sound producing activity. In one embodiment, the light is modulated to affect an imaging function, as a secondary effect, without substantially affecting a primary or main purpose of the light-producing activity. In another embodiment, the light is modulated to affect an imaging function, as a secondary effect, in conjunction with effects on the primary or main purpose of the light-producing activity. The invention is useful, for example, in TIG (Tungsten Inert Gas) welding where the light-producing arc, and possibly some light-producing utility lights, are modulated to improve a computer vision system (such as an auto darkening welding helmet or a headup display for a welding helmet) that helps a person see better. Cybernetic and physiological sensing is disclosed such as EEG, ECG, and the like, in conjunction with wearable computing.

  • Publication number: 20120176767
    Abstract: An LED work light, having a housing comprising a head section, and a foot section and a handle section each connected by hinges between the head section and the handle section and between the handle section and the foot section. The head section and foot section are hinged about the handle section by hinge means. Light is produced by one or more LEDs in the head section. Knobs are used to continuously adjust between magnitude of overall light output and excess-vs-insufficiency of red spectral content in the light produced by the LED work light. Magnitude of light produced is selected by choice of pushbuttons. Heat produced by LEDs and dissipated into the head section can be conducted from the head section to the handle section by the hinge means used to connect the head section to the handle section.

  • Patent number: 7922347
    Abstract: The inventive surgical light comprises a body provided with main light-emitting diodes and additional light-emitting diodes arranged therebetween, which are spaced on said body and fixed thereto, wherein said additional light-emitting diodes are grouped and are characterised in that the spatial orientation thereof differs from the spatial orientation of the main light-emitting diodes. A light field control device comprises a control unit to which the groups of light-emitting diodes are connected by means of adjusters each of which is connected to a power supply unit. The main light-emitting diodes are fixed to the light body in such a way that the optical axes thereof cross the light axis in the center of a light spot. The additional light-emitting diodes are fixed to the light body in such a way that the optical axes thereof form a concentric light spot in the form of a ring around the main light spot.

  • Patent number: 7862207
    Abstract: Systems and methods are provided for imaging a planar specular object such as a semiconductor wafer. In one embodiment, an imaging system for imaging a defect on a planar specular object includes a telecentric lens having a sufficiently aspherical surface such that the telecentric lens is substantially corrected for an optical aberration. The imaging system also includes a telecentric stop including an aperture therein to block light reflected from the planar specular object while allowing light reflected from the defect to pass through the aperture. The imaging system further includes a lens group having a system stop positioned between the telecentric stop and the lens group. The lens group is substantially corrected for the optical aberration independent of the telecentric lens.
