摘　　要：研制了材料光反射特性测定装置,该系统通过上下两个直径、分度相等且同轴的重叠刻度转盘装置,实现对建筑表面材料光反射空间分布情况的测定,即对材料不同入射角度(0～180°)、不同观测角度(0～180°)的亮度反射特性和色度反射特性进行系统测定。对装置的构成、工作原理、实验方法及数据分析、应用结果等进行了分析。结果表明,该系统为研究建筑材料表面的光反射特性提供了有效的实验条件,并对城市夜景照明和城市建筑色彩的研究具有应用价值。This paper introduces a self-developed apparatus for measuring light reflection characteristics of materials.The system realizes the measurement of the spatial distribution of light reflection of building surface materials by two overlapping dial devices with the same diameter,equal indexing and coaxial.In other words,the luminance and chromaticity reflectance characteristics of materials with different incident angles(0~180°)and different observation angles(0~180°)are systematically measured.The composition,working principle,experimental method,data analysis and application result of the apparatus are analyzed and discussed.It has been proved that the apparatus system provides an effective experimental condition for the study of the light reflection characteristics of building materials,and it has important application value to the study of urban nightscape lighting and urban architectural color.
