Abstract
Une méthode de faire fonctionner un système déclairage DEL produisant une couleur ciblée est proposée. Le système DEL comprend un capteur de couleur et trois émetteurs DEL ou plus, chacun fonctionnant à un réglage dexcitation démetteur contrôlable. La méthode propose au moins une matrice détalonnage qui définit une relation entre des mesures obtenues du capteur de couleur, représentée par des coordonnées de points de couleur de capteur, et des coordonnées de points de couleur absolus dans un espace de couleur absolu. Dans certains modes de réalisation, une matrice détalonnage définissant une relation non linéaire entre les deux espaces de couleur est proposée. Dans dautres modes de réalisation, des matrices détalonnage individuelles sont proposées pour chaque émetteur DEL.
