An electronic ballast system controls one or more ballasts of HID or fluorescent lamps, which are controlled in an "on/off" manner by a ultra low power controller that is isolated for a primary power circuit or derives its very low switch power from the ballast itself. The on/off control provides a near lossless control system. This system may be applied to electronic ballast for operates at fractional power levels corresponding to different lighting intensities and with conventional occupancy sensors. The system may also be applied to other electronically compatible end-use devices and applications.

L'invention porte sur un système de ballast électronique asservissant un ou plusieurs ballasts (66) de lampes à décharge haute intensité ou de lampes fluorescentes (67) à commande <= d'allumage/extinction >= par un contrôleur de très faible puissance isolé d'uncirucit de puissance primaire ou qui prélève sa très faible puissance de commutation directement dans le ballaste. Ce système fonctionne quasiment sans perte. Lorsqu'on utilise des capteurs de présence conventionnels, le système, appliqué à un ballast électronique, permet des niveaux de différentes puissance fractionnels correspondant à autant d'intensités d'éclairage différentes. Le système peut également être appliqué à d'autres applications ou dispositifs utilisateurs terminaux compatibles électroniquement.
