暗视觉测量及中间视觉评价体系——以1980A彩色亮度计为测试工具

Evaluation System of Dark Vision Measurement and Mesopic——To color luminance meter 1980A as test tools

文章提出了亮度低于明视觉条件下照明的技术关键以及对相关测色仪器的选型。建立中间视觉光度学系统一直是国际照明界研究的热点,1980A彩色亮度计亮度测试范围宽达10-4cd/m2到108cd/m2,有两组滤波器旋转支架,每组可分别装入七种光片,因此可以实现在一台1980A分别装入明视觉滤光片PHOTOPIC和夜视滤光片Scotopic(night vision)Filter,可以实现分别测量和研究相应情况下人类的明视觉和暗视觉准确获取S/P数值,在照明领域有广泛应用价值。

This paper presents the lighting key technology and related color measurement instrument selection in the brightness under photopic conditions. The establishment of mesopic photometry system has been become the research focus of the international lighting. Color luminance meter 1980 A has a wide measurement range up to 10- 4cd /m2 to 108 cd /m2,and two sets of filter rotating bracket,each set can be respectively containing seven kinds of optical film. thus it can be implemented in a 1980 A which are respectively arranged in the photopic vision filters and scotopic vision filters,and can realize the measurement and study under the corresponding condition and obtain accurately S /P value ofhuman photopic and scotopic vision. It has the widespread application value in the field of lighting.
