Whiteness metric for light sources of arbitrary color temperatures: proposal and application to light-emitting-diodes. | LitMetric

AI Article Synopsis

  • The study focuses on measuring how whiteness is perceived under different lighting conditions, specifically from various light sources with different color temperatures.
  • An existing metric, CIE whiteness, is evaluated and modified to work for light sources of any color correlated temperature (CCT).
  • Results demonstrate that optimizing the light spectrum, especially using LED technology, is crucial for effectively displaying whiteness.

Article Abstract

We study the quantification of whiteness perception under illumination from various light sources. We discuss an existing metric for sources with high correlated color temperature (CCT), CIE whiteness, and propose a procedure to adapt it to sources of any CCT. We illustrate our approach by comparing the ability of different warm-white sources to render whiteness. We show that a careful engineering of the spectrum -facilitated by the flexibility of light-emitting diode sources - is essential to render whiteness.
