Abstract:
Methods for generating a customized spectral profile, which can be used to generate a corresponding filter. A trial source spectrum is generated. An uncorrected lamp source spectrum is determined. One or more optical indices are calculated using the trial source spectrum or the uncorrected lamp source spectrum, and one or more of the optical indices are optimized by varying the trial source spectrum to generate the customized spectral profile.

Abstract:
A color identifying display system having alighting surface (111, 211, 501, 611) having an alterable apparent surface color, a color capture device (105, 205, 317, 507, 603) to capture a color of an object (109, 203, 305, 503) placed within a detection area, and a processor (113). The lighting surface (111, 211, 501, 611) and the color capture device (105, 205, 317, 507, 603) are coupled to the processor (113). The processor (113) analyzes the captured color to determine a prominent color of the object (109, 203, 305, 503) and to control a color of the lighting surface (111, 211, 501, 611) based on the determined prominent color The color of the lighting surface (111, 211, 501, 611) may be adjusted to match the prominent color, complement the prominent color, or be analogous to the prominent color

Abstract:
An apparatus for emulating various known night sky illumination conditions. The apparatus comprises a plurality of electrically-powerable LEDs which are disposed in an array and have respective spectral curves centered at different wavelengths in the visible to the short wave infrared wavebands, and means for fixing the temperatures of the LEDs to avoid temperature-induced changes in their spectral curves. Additionally, the apparatus includes means for varying the light intensities of the individual LEDs so that the combination of their spectral curves matches the spectrum of the known night sky illumination condition to be emulated, and means for regulating the total amount of light collected from the array so that the cumulative spectrum has the same intensity as the known night sky illumination condition to be emulated.
