Adopting the correction method outlined in the IEC 891 Standard,all non-STC IeV curves are subsequently corrected. Corrected IeV curves are plotted in Fig. 9. Small deviations compared to the Class AAA curve are significant.
This is the first instance that the IEC 891 correctionmethodisapplicable for LEDsimulators.
Works of Kohraku,S. and Kurokawa, K. described above use a different correction method, called theTwo-curvemethod. Other research works give less explicit description on how non-STC results are corrected.
