This article discusses the use of light-emitting diodes to generate white light – a research forefront in Physics and Ergonomics. We first present various technological approaches to white-light generation. After a general introduction to the human vision system, we discuss two key aspects of the quality of white light: the color of the light itself, and the color rendering of illuminated objects. We present the tools underlying modern color science, and review key color rendering metrics, from the well-known color rendering index to the latest improvements in the field.

Cet article présente l'utilisation des diodes électroluminescentes comme sources de lumière blanche – un sujet à la pointe de la recherche en physique et en ergonomie. Nous présentons d'abord diverses approches technologiques à la génération de lumière blanche. Après une introduction générale au système visuel humain, nous discutons deux aspects cruciaux de la qualité de la lumière : la couleur intrinsèque de celle-ci et le rendu des couleurs des objets illuminés. Nous présentons les outils sous-jacents à la colorimétrie moderne, et examinons les principales métriques du rendu des couleurs : le CRI, ainsi que les derniers progrès dans le domaine.
