光源的顯色性

　　美國(guó)國(guó)家標(biāo)準(zhǔn)與技術(shù)研究所（NIST）提出一個(gè)顏色質(zhì)量尺度（CQS），旨在解決目前廣泛使用的顯色指數(shù)對(duì)于固態(tài)照明的許多缺點(diǎn)。

　　這個(gè)顏色質(zhì)量表（CQS）是由（NIST）輸入從照明行業(yè)和國(guó)際照明委員會(huì)（CIE）地址的CIE顯色指數(shù)（CRI）問(wèn)題的固態(tài)光源，以滿足照明行業(yè)的新需求和消費(fèi)者溝通的照明產(chǎn)品的顏色質(zhì)量。計(jì)算法的方法是基于用于CRI方法的修正。雖然模擬支持了CQS的適宜性和有效性，視覺(jué)實(shí)驗(yàn)將進(jìn)行改進(jìn)和驗(yàn)證法。然后，它將被提議作為一個(gè)新的國(guó)際標(biāo)準(zhǔn)。

　　Color rendering index vs. color quality scale

　　The color appearance of objects under artificial lighting is an important characteristic of light sources， particularly to consumers. Currently， the only internationally-accepted assessment procedure for evaluating the color appearance of objects under light source illumination is the CIE color rendering index （CRI）。

　　In the calculation of the CRI， the color appearance of 14 reflective samples is simulated when illuminated by a reference illuminant and the test source. After accounting for chromatic adaptation with a Von Kries correction， the difference in color appearance Ei， for each sample， between the test and reference illumination， is computed in CIE 1964 W*U*V* uniform color space. The special color rendering index （Ri） is calculated for each reflective sample by：
