Abstract

La présente invention concerne un procédé de commande en boucle fermée qui régule l'intensité lumineuse d'une lampe PL-S dans une longueur d'onde en détectant le rendement lumineux de la lampe dans une autre longueur d'onde et en commandant la puissance de la lampe par modulation de phase c.a.. De préférence, ce procédé régule l'intensité de la lampe en réaction à une lumière détectée émise par la lampe. Ce procédé permet de corriger la variabilité de fabrication de la lampe et du ballast, les effets de la température, les fluctuations de la tension de ligne, et le vieillissement de la lampe. Le dispositif de commande peut déterminer l'intensité d'un certain nombre de groupes de lampes, n'importe quelle lampe pouvant être attribuée à n'importe quel groupe. Une fois la détection d'une longueur d'onde de lumière visible et la commande de la longueur d'onde UV déterminées, la variabilité de l'intensité de la lumière UV est commandée dans une plage ±40 νW/cm2 à un niveau 12,000 νW/cm2 (mesuré sensiblement au niveau de la lampe), représentant 33 % d'erreur; le besoin de mesurer l'intensité du processus n'intervenant qu'à des intervalles PMS réguliers. Le dispositif de commande surveille et signale le grillage de la lampe et l'étape proche de la fin de vie de la lampe. Les circuits de mise sous tension sans appel de courant empêchent les contraintes de cyclage marche/arrêt et les lampes de cyclage seulement lorsque les rendements recherchés augmentent la durée de vie utile de la lampe. Par ailleurs, ce système réduit généralement à quelques minutes les longues périodes de mise en fonctionnement connues dans les techniques précédentes.
