Abstract: In order to obtain the quantitative influence law of common light sources of museum exhibits on Chinese traditional heavy colour painting and the lowest damage light source applicable to different types of painting, the paper chose halogen tungsten lamp, metal halide lamp and WLED as experimental light source long-term illuminating five kinds of inorganic pigment commonly used in Chinese traditional heavy painting: cinnabar, orpiment, azurite, clam powder and graphite. Then, the Raman spectra? parameters of samples were measured by microscopic Raman spectroscopy before and after illumination of different types of light sources. Based on the measured data, the spectra diagram that scattering light intensity varies with Raman shift were drawn. Through the analysis of spectra diagram, the quantitative influence of three typical light sources on the molecular structure of different pigments was obtained. Then the quantitative influence law of light sources on Chinese traditional heavy colour painting was obtained.
