人类工效学.易接近式设计.彩色光用与龄期相关的辉度对比规范

[中文适用范围]： 本国际标准规定了任何年龄的人看到的任何两种不同颜色的光与年龄相关的亮度对比度，考虑到眼睛光谱发光效率与年龄相关的变化。 本国际标准提供了可应用于照明、视觉标志和显示器设计的基本计算方法。 它适用于在中等亮度条件下看到的视觉标志和显示器中的自发光或反射光，称为明视觉，其光谱辐射率是已知或可测量的。 它不适用于在较暗条件下看到的光，称为中间视觉或暗视觉。 本国际标准规定了10岁至79岁、眼睛未接受过可能影响其光谱发光效率的医疗或手术的人群的亮度对比度。 本标准不适用于光谱发光效率与色觉正常者不同的色觉缺陷者所看到的视觉标志和显示器，也不适用于低视力者所看到的视觉标志和显示器。 [外文原描述]： ISO 24502:2010 specifies the age-related luminance contrast of any two lights of different colour seen by a person at any age, by taking into account the age-related change of spectral luminous efficiency of the eye. ISO 24502:2010 provides a basic method of calculation that can be applied to the design of lighting, visual signs and displays. It applies to light, self-luminous or reflected, in visual signs and displays seen under moderately bright conditions called photopic vision and whose spectral radiance is known or measurable. It does not apply to light seen under darker conditions called mesopic or scotopic vision. ISO 24502:2010 specifies the luminance contrast for people aged from 10 to 79 years who have had no medical treatment or surgery on their eyes that may affect their spectral luminous efficiency. ISO 24502:2010 does not apply to visual signs and displays seen by people with colour defects whose spectral luminous efficiency is different from those with normal colour vision, nor those seen by people with low vision.
