建筑饰面材料色度反射性能测量及方法

Measurement methodology of color reflection performance of building facing materials

采用反射光谱数据的测量方法,通过对照明观测角度、光源色温、视场影响的实验测量,发现建筑饰面材料色彩的观测结果与光线入射角和观测角度有关。在光线入射角和观测角度改变时,色度值会有所变化,观测结果与材料表面材质有关。镜面反射方向附近色度波动较大,其他角度色度数据稳定,亚光型面砖的镜面反射现象并不明显,光源色温影响材料颜色,光入射角发生改变时材料色度值发生变化。这些研究为建筑色彩设计提供了定量研究的理论基础。

With the measurement of reflection spectrum and the experimental measurement of illumination observing angle, color temperature of light source, effects of field viewing angles, it is found that the color of facing materials have relation to light incidence and observing angle. The ehroma number varies with the changing of light incidence and observing angle based on the features of facing materials. The chroma number has more fluctuation with the angle close to mirror reflection direction while it is more steady with other angles. Besides, the mirror reflection phenomenon is not obvious for sub-brightness facing tile The color temperature of light source affects material color and the chroma number varies with the incidence changing, etc. All of these have provided fundamental for quantitative study of architecture color design.
