Visual perception of many manufactured white objects is driven by the concentration of
fluorescent whitening agents (FWAs) that they contain. FWAs serve to increase overall …

This article describes a method for calculating and specifying light source chromaticity using
the International Commission on Illumination (CIE) 2015 10° color matching functions …

Light-emitting diodes (LEDs) are solid-state sources, where the emitted light depends on the
characteristics of the semiconductor material. It is usual to call an LED a light-emitting diode …

Durch die Einführung der LED (Light Emitting Diode) als gängiges Leuchtmittel in der
Innenraumbeleuchtung ergeben sich neue Anforderungen an die Charakterisierung von …

To create a numerical description of color (eg, X, Y, Z), one applies a Color Matching
Function to spectral power distribution data acquired with an instrument such as a …

Placement of radiant power at different wavelengths within the visible spectrum affects our
visual perceptions, such as color perception, brightness perception, and whiteness …

LEDs with identical color temperatures or chromaticity coordinates do not always appear the
same for a human observer. This is due the fact, that the known color matching functions are …

I was interested to read in your Correspondence section in the previous issue the comments
made by David Loe as a reaction to Howard Brandston's Opinion paper. I have a lot of …
