摘　　要：竹丝是一种重要的室内装饰材料。为探索室内光环境下竹丝装饰材料光变色规律,以本色丝和炭化丝装饰材为试验材料,在人工模拟状态观察其变色过程,通过色度值测试和反射光谱曲线的分析,研究光照前后竹丝装饰材的光变色性能。结果表明:室内光能够引起竹丝表面颜色发生变化,随着光照时间的增加,色差值随之增加,炭化丝出现淡色效应,表面颜色变浅,明度增加,而本色丝则表面颜色变暗,明度减小,两者色值参数变化呈现出不同规律,炭化丝装饰材的光稳定性明显高于(变色速率低于)本色丝装饰材。In order to investigate the light coloration of decorative bamboo filament which was an important indoor decoration materias in indoor environments, the color changing process of bamboo filament was observed in artificial state,which contented natural color and thermally mo-dified bamboo filament as experiment materials. The chromatic value of decorative bamboo filamen-t before and after illumination of light induced was tested by color value tests and reflectance spectra.analysis.Results showed that indoor light could cause the color changes on the surface. With the increase of illumination time, color difference increased, discoloration effect appeared in thermally modified filament, the color became lighter and the value of light-ness increased. Oppositely, color of the natural color bamboo filament became darker and lightness decreased,color parameters variation was different between the two kinds of bamboo filament. Compared tonatural colour bamboo filament,thermally modified filament had the significantly higher photosta-bility （ discoloration rate was lower） than that of natural color filament.
