The present invention comprises a method and system for controlling the chromaticity and luminous flux output of a digitally controlled luminaire. The luminaire comprises one or more light-emitting elements and one or more light sensors which can provide optical feedback, wherein this optical feedback is filtered to remove undesired frequencies. The method and system comprises a control system which can sample the filtered signals from the light sensors according to a predetermined feedback sampling frequency scheme, wherein this scheme is specifically configured to provide sufficient iterations of the feedback loop to be performed for adjustment of the chromaticity and luminous flux output of the light-emitting elements, without perceptible visual flicker or momentary chromaticity shifts.

L'invention comprend un procédé et un système de commande de la chromaticité et de la sortie du flux lumineux d'un luminaire à commande numérique. Ce luminaire comprend un ou plusieurs éléments électroluminescents et un ou plusieurs photodétecteurs qui peuvent assurer une contre-réaction optique, celle-ci étant filtrée pour supprimer les fréquences indésirables. Ces procédé et système comportent un système de commande capable d'échantillonner les signaux filtrés émis par les photodétecteurs selon un schéma de fréquence d'échantillonnage de contre-réaction prédéterminé, ce schéma étant spécifiquement configuré pour garantir des itérations suffisantes de la boucle de contre-réaction appliquée pour ajuster la chromaticité et la sortie du flux lumineux des éléments électroluminescents, et ce sans clignotement perceptible ou décalages momentanés de chromaticité.
