LRV & NCS 代码
建筑行业的光反射值(LRV)是衡量物体被光源照射时，表面反射光光和入射光百分比的一种指标。LRV与材料表面的色彩有很大关系。某种颜色的LRV表明它反射能力的强弱。黑色的光反射值为0%，可吸收所有入射光。白色的光反射值为100%，带来明亮、凉爽的室内基调。这一指标也决定了室内光源的布置方案。浅色环境需要的光照量较小，因此可有效地节约能源。所有福尔波产品均标识光反射值，客户可在产品介绍页面的产品描述中查阅该指标。
NCS色彩编码对任何材质的显色进行描述。色彩编码，即所谓的NCS标记，如NCS S 1080-Y70R，可精确描述材质呈现的色彩。NSC已定义1950份标准色彩，并以10个色阶为单位，呈现整个色彩空间。无论是否属于1950种标准色彩，同一色彩标记下不同样本的色彩也各有不同。通过这一体系，客户可以在色谱中找到与地板颜色匹配的色彩系列，用于房屋内其他设施。
What is LRV & NCS?
In architecture, Light Reflectance Value (LRV), is a measure of the percentage of visible and usable light that is reflected from a surface when illuminated by a light source. The LRV can be linked to a number of decisions on which colour can be chosen. The approximate LRV of a colour indicates the amount of visible light that a colour will reflect. Black has a light reflectance value of 0% and absorbs all light. White has a light reflectance value of 100% and keeps a building light and cool. It also links to the use of electricity where lighter colours need less lighting which is a direct saving for the environment. All Forbo products carry a light reflection value, which can be found on the collection pages with the description of each item.
NCS colour coding describes the colour of any material. With numeric colour codes, so called NCS Notations, such as NCS S 1080-Y70R, any colour can be described precisely. NCS has defined 1950 standardised colours at every tenth step of the colour space to represent the entire colour space. Each notation's colour sample is visually identical to any other colour sample of the same notation, whether it is a standardised colour or a colour in between the 1950 standard colours. This way you can find matching flooring colours with other coloured items in a room.
