  • Patent number: 11388794
    Abstract: A method and an illumination system for simulating a CIE standard illuminant with a multi-channel LED are disclosed. The method includes adjusting a brightness of the main light source control channel, the wavelength complementary control channel, the color temperature adjustment control channel to make a mixed chromaticity coordinate meet a chromaticity coordinate of the CIE standard illuminant to be simulated according to chromaticity coordinates. The LED control channels are reduced through group optimization, and a technology which is discarded by multi-channel LED such as a filter is used, a control of a light source substantially reducing number of control channels and enabling a multi-channel LED to simulate a standard illuminant is formed, such that a single chromaticity control rather than a chromaticity control which must be transformed by a spectral conversion is achieved.

  • Patent number: 9964438
    Abstract: A system and a method for transporting high luminous intensity light from at least one luminaire to a destination area are disclosed. The system may include a light guide that carries light from the luminaire to a plurality of sensors located on a Printed Circuit Board (PCB). The PCB may be attachable anywhere the luminaire is located. According to an aspect, the luminaire is a separate entity from the sensor system. While collecting light rays originating from the luminaire and delivering them to the light sensors, the light guide may perform a plurality of operations to modify the characteristics of the collected light rays. The plurality of operations performed by the light guide on the light rays may support the accuracy and longevity of the light sensors on the PCB. Further, the light guide allows the sensor subsystem to be proximal to or distant from the luminaire.

  • Patent number: 9841322
    Abstract: A spectrometric device for optical analysis of material composition, coating thickness, surface porosity, and/or other characteristics uses several monochromatic light sources—e.g., laser diodes—to illuminate a sample, with a camera taking an image of the sample under each source's light, and with the various images then being combined to generate a (hyper)spectral image. To address the difficulty in obtaining uniform illumination intensity across the illuminated sample area with solid-state light sources, the output from the light sources may be supplied to an integrating sphere (preferably after being combined within a fiber combiner), and then to a fiber bundle whose output ends are configured as a ring light (a ring of fiber ends directing light at a common spot). The camera may then focus on the spot, at which the sample may be placed for illumination and imaging.

  • Patent number: 9477041
    Abstract: The present invention is directed to a beam dump which is configured for not increasing a temperature of a laser with which it may be implemented. The beam dump may include an opaque enclosure which is configured for receiving light (ex.—initial light) from a light source (ex.—a frequency-converted laser), said light being delivered through an aperture of the enclosure via one or more connected optical fibers. The received light may be scattered within the enclosure. However, the beam dump is configured for minimizing the amount of light which is back scattered light into the fiber(s). For instance, the amount of back scattered light may be less than 1/1000 of the initial light. Further, the beam dump may be configured for minimizing photocontamination which may be caused when the light contacts interior surfaces of the enclosure. Still further, the beam dump may be a small size, low cost structure.
