摘　要:分析了分光法測試發(fā)光二極管（LED）顏色的測量不確定度，著重分析了光譜功率分布測量不確定度和波長不確定度對顏色測量的不確定度影響，給出了幾種典型LED的分析結果，結果表明，5％的光譜功率分布測量不確定度和0．5nm的波長不確定度在一般情況下可以滿足精度要求為0．001的LED顏色測量。[著者文摘]

State Key Lab of Modem Optical Instrumentation, Zhejiang University,Hangzhou 310027,ChinaAbstract:The measurement uncertainties in the color measurement of LEDs by spectroradiometric method are analysed,and the analysis focuses on the uncertainty contributions of spectral power distribution and wavelength uncertainty. Several typical results are given, The results show that 5% relative uncertainty of spectral power distribution and a 0.5 nm wavelength uncertainty are enough for the measurement for LED color with high accuracy of 0. 001.[著者文摘]
