摘要：
Photometric and colorimetric parameters are important evaluations criterion of the performance of LED light sources. Photometric and colorimetric parameters of LED were measured using PMT spectroradiometer and CCD spectrometer respectively in this research, the result was discussed and the common method was improved. The result of experiment indicated that temperature drift of PMT spectroradiometer was compensated effectively by introducing reference standard light source; measurement accuracy of CCD spectrometer was improved significantly with standard LED. CCD spectrometer suitable for the industrial application for its rapid measuring speed, PMT spectroradiometer should be used in scientific research for its high measurement accuracy according to the experimental results.
