Colour rendition quality of typical fluorescent lamps determined by CIE Colour Fidelity Index and Colour Rendering Index

摘要

This paper describes how CIE colour fidelity index R_f values are correlated with CIE R_a colour rendering index values for typical FL fluorescent lamps. The results shows that for broad band FL lamps R_f doesn't introduce drastically changes in relation to R_s values. The other situation is with narrow band FL lamps whose spectral power distribution was designed for achieving of high R_a value. At that case there is no correlation between R_a and R_f.
