  • Patent number: 10091852
    Abstract: A method may comprise: supplying light energy from a light emitting device principally along a first axis; sensing the light energy with a light sensing device oriented along a second axis, wherein the second axis is oriented substantially orthogonally to the first axis; and adjusting the light energy in response to the sensed light energy. In this way, an amount of retro-reflected light incident at the light sensing device may be reduced, measurement error of the light sensing device may be reduced, and control precision and reliability of the lighting system for curing a work piece can be increased.

  • Patent number: 10076005
    Abstract: A lighting device may comprise a light emitting element and a reflector, the reflector comprising: a first opening surrounding the light emitting element and a second opening; reflector side walls forming the first and second openings, the reflector side walls divergently extending from the first opening away from the light emitting element to the second opening; and corner facets, wherein each corner facet is positioned over a corresponding reflector corner formed by an adjacent pair of reflector side walls at the first opening. In this way, a photosensitive work piece may be uniformly irradiated while mitigating under-curing and over-curing, and while reducing a coupling optics size and a distance between the light emitting elements and the work piece, thereby decreasing cure times and lowering manufacturing costs.

  • Publication number: 20180238845
    Abstract: A liquid chromatography flow cell including an integrated light source and an integrated detection chamber. The integrated light source includes a plurality of light emitting diodes (LEDs), wherein each LED emits light of a specific wavelength. The light emitted from the integrated light source is directed to pass through a sample in a flow chamber of the flow cell without any optical conditioning, and the light not absorbed by the sample flows out of the flow chamber directly into the integrated detection chamber, where an intensity of the unabsorbed light is measured by detectors coupled to the integrated chamber.

  • Patent number: 9764049
    Abstract: A method of irradiating a work piece may include forming a cutout recessed from a surface of a light guide, positioning the work piece inside the cutout, irradiating a light input surface of the light guide with UV light, and guiding the UV light from within the light guide through recessed surfaces of the cutout to irradiate the work piece. In this way more uniform irradiation of all curable surfaces of a work piece may be achieved, the energy and time consumed during irradiation of the work piece may be reduced thereby lowering operating costs, and the radiation delivery system may be made more compactly, thereby making it more convenient and practical for daily applications.

  • Publication number: 20170146804
    Abstract: An apparatus comprising a human vision solid state display filter material with a first and a second surface with a semitransparent material between. The first surface, the second surface, the semitransparent material or combinations thereof have a spectral pass-band and an off-band, the pass-band comprising at least three spectrally discrete bands that overlap with emission peaks from a solid state display and the off-band rejecting a portion of the human visible spectrum. Wherein a transmitted ratio of the pass-band to the off-band increases human visual perception of the solid state display when viewed under ambient light conditions.

  • Patent number: 9638833
    Abstract: A device for UV curing a coating or printed ink on a workpiece such as an optical fiber comprises at least two UV light sources equally spaced around a central axis, each UV light source comprising a reflector and a cylindrical lens, and the UV curing device configured to receive a workpiece along the central axis. The reflectors are configured to substantially reduce the emitting angle of light from the UV light sources, thereby directing the light substantially through the cylindrical lenses, the cylindrical lenses focusing the light intensely along a surface of the workpiece.
