Title
(EN) CONTROLLING AN ARRANGEMENT OF SEMICONDUCTORS EMITTING LIGHT OF DISTINCT COLORS
(FR) CONTROLE D'UN SYSTEME DE SEMI-CONDUCTEURS EMETTANT DE LA LUMIERE DE DIFFERENTES COULEURS
Abstract
(EN) Controlling an arrangement of semiconductors of which different semiconductors emit light of different distinct colors is disclosed, whereby a feed forward control part, which is dependent on a junction temperature of semiconductors for each color, is operated with first intervals and is adjusted dependent on measure light output for each color with much longer second intervals.
(FR) L'invention concerne le contrôle d'un système de semi-conducteurs, les différents semi-conducteurs émettant une lumière de différentes couleurs. Une partie de contrôle de couplage vers l'avant qui dépend d'une température de jonction de semi-conducteurs de chaque couleur, fonctionne avec un premier intervalle et est ajustée en fonction de la sortie de lumière de mesure de chaque couleur à des deuxièmes intervalles nettement plus longs.
