    Abstract: A method of light source classification includes determining a plurality of color regions in the CIE 1976 chromaticity diagram according to desired classification criteria. The plurality of color regions of the CIE 1976 chromaticity diagram are converted into a plurality of color classification regions defined by color coordinates of the CIE 1931 chromaticity diagram. The light source is classified into one of the plurality of color classification regions. This classification method may allow for precise classification based on actual color differences, while providing light sources having color uniformity in the same classification region.

    Abstract: A method for characterizing a primary radiant spectra of a projector includes projecting primary colors with a projector having a projector lamp and color filters. Measurements of each primary color are taken with a multi-band camera. Spectra of the color filters are estimated using the measurements from the multi-band camera. The primary radiant spectra of the projector are estimated using spectral data of the projector lamp and the estimated spectra of the color filters.

    Abstract: The present disclosure is directed to imaging device, systems, and methods for collecting optical data for use with spectrometers. An imaging device configured in accordance with one aspect of the disclosure includes a lens configured to introduce light into the imaging device along an optical path, and an image sensor spaced apart from the lens and configured to receive at least a portion of the light along the optical path. The imaging device further includes a filter assembly positioned between the lens and the image sensor, and a reflector or mirror carried by the filter assembly. The filter assembly is configured to move the reflector between first and second positions. In the first position the reflector is at least partially aligned with the optical path and reflects at least a portion of the light to a corresponding light input for a spectrometer. In the second position the reflector is positioned outside of the optical path.

    Abstract: An illumination system comprises at least two light sources (101,102,103) having different emission spectra to one another; a detection circuit (131,132,133) for sensing a light intensity using at least one of the light sources as a photosensor; and driving means (161,162,163) for driving the light source in dependence on the sensed spectral distribution of light. The emission spectrum of a light source with the smallest bandgap overlaps the emission spectrum of a light source with the second-smallest bandgap. The illumination system is possible to measure the intensity of light emitted by the light source with the smallest bandgap by putting the light source with the second-smallest bandgap in detection mode. The illumination system may also sense the spectral distribution of ambient light, to allow the output from the illumination system to be adjusted in dependence on the ambient light.

    Abstract: A system for generating a colored light comprises a set of illuminant types and a processor. The set of illuminant types is associated with a chromaticity gamut, and the set of illuminant types comprises at least five illuminant types that are each associated an illuminant type hue angle. The processor is configured to determine, based at least in part on a mapping, an output level set for a received color coordinate. The mapping comprises associating each color coordinate with an output level set that uses a set of hue-adjacent illuminant types. Hue-adjacent illuminant types comprise a group of illuminant types that are determined to be adjacent in a circular ordered list of illuminant types that is circularly ordered according to the illuminant type hue angle.

    Abstract: A method of determining a modified spectral content of a light emitting diode (LED) light engine includes separating spectral data from the LED light engine into at least two spectral component bands, calculating respective efficacies for each of the at least two spectral components, simulating a first LED spectral component for a predetermined peak position and intensity, modifying spectral data from an existing LED to match a predetermined peak wavelength, applying factorial design-of-experiment techniques to the simulated first LED spectral component and the modified spectral data to obtain a selection of spectra, and selecting a spectrum from the results of the applying step, wherein the selected spectrum includes characteristics of the modified spectral content. The method includes the step of producing a LED light engine/electronic driver combination having the selected spectrum. A non-transitory medium having computer executable instructions is disclosed.
