ABSTRACT

Using comparative and iterative analyses of three-component spectral power distributions, this work demonstrates the advantage of locating radiation about the prime color wavelengths (near 450, 530, and 610 nm) over the anti-prime color wavelengths (near 490, 570, and 650 nm) for the purpose of maximizing color discrimination as measured by the Total Light Source Error Score, R_d. To maximize color discrimination (minimize R_d) most effectively in the design of a three-component spectrum, locate the primaries about the prime color wavelengths and increase their spectral width up to a full-width at half-maximum of 60 nm, at which R_d is minimized. This work also details the internal logical consistency of quantifying color discrimination of a light source using R_d, whereby the color discrimination ability of the daylight spectrum is set as ideal color discriminator meant to be replicated, not exceeded. Such internal logical consistency does not exist with quantifying color discrimination using gamut area, where is it demonstrably simple to exceed the performance of daylight (i.e., R_g ≥ 100).

摘要

通过对三分量光谱功率分布的比较和迭代分析，这项工作证明了定位原色波长（接近 450、530 和 610 nm）相对于反原色波长（接近 490、570 和650 nm），以最大限度地提高由总光源误差分数R _d测量的颜色辨别能力。为了在三分量光谱的设计中最有效地最大化颜色辨别力（最小化R _d），将原色定位在原色波长附近，并将它们的光谱宽度增加到 60 nm 的半峰全宽，此时Rd _{_}被最小化。这项工作还详细说明了使用R _d量化光源颜色辨别的内部逻辑一致性，从而将日光光谱的颜色辨别能力设置为旨在复制而不是超过的理想颜色辨别器。这种内部逻辑一致性在使用色域区域量化颜色辨别时不存在，在这种情况下很容易超过日光的性能（即R _g ≥ 100）。
