Abstract：This paper systematically analyzed the spectral fitting degree between typical artificial light sources and sunlight,comparing the spectral characteristics of LED,incandescent,fluorescent,and other light sources using evaluation methods such as cosine similarity and Goodness of Fit Coefficient(GFC).Results showed that incandescent and halogen lamps exhibited the best spectral continuity and higher fitting degrees.LED light sources significantly improved their fitting performance through multi-primary color mixing and violet excitation technologies.This study provides a theoretical foundation for healthy lighting design,indicating that dynamic spectral regulation and intelligent dimming technologies are future development directions.
