    Abstract: PROBLEM TO BE SOLVED: To provide a white LED which does not require such a significant white balance adjustment as could lead to reduction in display luminance on a liquid crystal panel and which is selected so that a chromaticity variation on panel display fits within a desired range.SOLUTION: When the chromaticity of the primary light of a combinatorial LED composed of an LED element emitting primary light and a phosphor excited by the primary light to emit secondary light greater in wavelength than the primary light is within a predetermined range, an LED classification device (21) classifies the LED as the one which is to be used for the backlight of a liquid crystal display device. A coefficient calculation unit (26) and a correction chromaticity calculation unit (27) calculate for all of LEDs to be classified a correction value for the chromaticity obtained by assuming that the primary light has transmitted the color filter of the liquid crystal display device, and subtract the correction value from obtained chromaticity individually for all of LEDs to be classified to correct the chromaticity. A chromaticity rank classification unit (28) classifies the LED by chromaticity rank on the basis of the corrected chromaticity.

    Abstract: Methods and systems for modulating a manufactured light source are disclosed. Methods and systems of the present disclosure include sensor assemblies having first and second light sensors to retrieve light spectrum data at a target location, such as from a surface in an interior space at a home, office, or commercial building, that also receives daylight exposure. The first light sensor retrieves the light spectrum data within a spectrum of the manufactured light source. The second light sensor retrieves light spectrum data outside of the spectrum of the manufactured light source, yet within the spectrum of daylight. The light spectrum data is used to define spectral characteristics at the target location, such as a ratio of daylight to the manufactured light source, phase of daylight, and average overall quantity, which are used to maximize light-associated benefits of the spectral composition for the occupants at the target location, such as humans, plants, and animals.
