Abstract: The color of light emitted by an assembled light emitting diode (LED) based illumination device with at least two different wavelength converting materials is automatically tuned to within a predefined tolerance of a target color point by modifying portions of the wavelength converting materials. The color of light emitted from the assembled LED based illumination device is measured and a material modification plan is determined based at least in part on the measured color of light and a desired color of light to be emitted. The material modification plan may further include the location of the wavelength converting materials to be modified. The wavelength converting materials are selectively modified in accordance with the material modification plan so that the assembled LED based illumination device emits a second color of light that is within a predetermined tolerance of a target color point.

Abstract: The present disclosure provides a spectrophotometric colorimeter based on LED light source, wherein the spectrophotometric colorimeter includes an integrating sphere, a coupling light path, and a spectrometer. An inner wall of the integrating sphere is arranged with a composite light source consisting of eight LEDs; a sphere wall of the integrating sphere defines an incident aperture; light emitted from each LED enters an interior of the integrating sphere through the incident aperture and is irradiated onto the inner wall. The coupling light path is configured to couple light at a measurement caliber such that the light can enter an incident split and to eliminate stray light from the inner wall. After emitting out from an observation aperture of the integrating sphere, the light enters the incident split through the coupling light path and is irradiated onto a linear-array sensor after being split by a spectral light path; and different pixels of the linear-array sensor correspond to light radiation strengths at different wavelengths.
