摘要： A colorimeter 1 that measures a chromaticity of a measured object A comprises: a first light source unit 11 that emits first irradiation light having a first spectrum S1; a second light source unit 12 that emits second irradiation light having a second spectrum S2 different from the first spectrum S1; an integrating sphere 61 that has irradiation light including the first irradiation light and the second irradiation light incident thereon; a light receiver 20 that detects measured light resulting from irradiation of the measured object A with the irradiation light emitted from the integrating sphere 61; and a controller 50 that calculates an optical spectrum of the measured light based on a detection signal of the measured light. A superimposed spectrum S of the first spectrum S1 and the second spectrum S2 corresponds to a reference spectrum S0 of a standard light source as reference for calculating the chromaticity.

摘要： Multiple colors of light emitted by an assembled light emitting diode (LED) based illumination device is automatically tuned to within a predefined tolerance of multiple target color points by modifying portions of wavelength converting materials associated with each color. A first color of light emitted from the assembled LED based illumination device in response to a first current is measured and a second color of light emitted from the assembled LED based illumination device in response to a second current is measured. A material modification plan to modify wavelength converting materials is determined based at least in part on the measured colors of light and desired colors of light to be emitted. The wavelength converting materials may be selectively modified in accordance with the material modification plan so that the assembled LED based illumination device emits colors of light that are within a predetermined tolerance of target color points.
