Paper Abstract

A type of chromatic measuring system, which was based on the spectroradiometric method, controlled by a computer was developed. Spectra, chromaticity coordinates and correlated color temperature (CCT) of light-emitting diode (LED) can be real time measured by this system. It has high resolution of wavelength with 0.2nm, fast measuring speed and friendly operation interface. The measurement data indicate that the system has higher accuracy than CS-100. Difference between measured result and standard data of the system is within ± 2%, while repeatability is better than 98%.
