GUAN Zhong-su. Introduction to Optical and Color Measurement System for Light-emitting Diode[J]. Chinese Journal of Luminescence, 2003,24(6): 642-644DOI:
We designed and processed a Φ100mm measurement integral sphere
which connected with a fluorescence spectrophotometer by optical fiber
to meet the require of studies and application of white light-emitting diode for especial illumination.The system can measure the spectral power distribution of LED.On basis of the spectrum distribution
we can calculate the optical and colorimeter parameter of LED such as CIE color coordinate
color temperature
color rendering index and so on.This method can avoid color-correction which is necessary for general photometer and the large data error caused by color-correction.
