Abstract

Pour la commande de la puissance électrique en régime transitoire d'une lampe à décharge ne contenant pas de mercure ou en contenant une faible quantité, on détecte la valeur de variation se rapportant à la tension de la lampe par rapport à sa valeur initiale. Une unité de commande (11, 12, 13) est destinée à modifier le taux de variation temporel de la puissance électrique qui est fournie à la lampe à décharge pendant la période transitoire en fonction de l'augmentation de la valeur de variation ou du temps écoulé.
