  • LEDs light-emitting diodes
  • Functional advantages and benefits of LEDs include high energy conversion and optical efficiency, durability, lower operating costs, and many others.

Abstract

La présente invention concerne des procédés et un appareil innovants permettant d'enregistrer des données d'étalonnage d'unité d'éclairage. Selon un mode de réalisation, l'invention concerne un luminaire (100), doté d'un contrôleur (102), d'un bus (106) couplé au contrôleur, d'une pluralité d'unités d'éclairage (104) couplées au bus, et d'au moins une unité de fourniture d'informations (110) disposée sur une surface externe d'au moins une unité d'éclairage de la pluralité d'unités d'éclairage, lequel contrôleur est conçu pour déterminer, sur la base d'informations lues à partir de ladite ou desdites unités de fourniture d'informations, des données d'étalonnage électro-optique associées à ladite ou auxdites unités d'éclairage, et pour amener une ou plusieurs sources de lumière (108) de ladite ou desdites unités d'éclairage à être alimentées de manière sélectionnée en fonction au moins en partie des données d'étalonnage électro-optique associées à ladite ou auxdites unités d'éclairage.
