  • Digitized electronic ballasts for fluorescent lamps have been on the market since the beginning of 1998, and can process both DC and AC voltage at their input. When DC voltage is present, the luminous flux and the current consumption of the fluorescent lamp are automatically reduced. The value of the luminous flux or the current consumption can be programmed in the digital electronic ballast.

Abstract

L'invention concerne un élément lumineux de secours (NLE) utilisé pour actionner des lampes fluorescentes (LA) en cas de panne de secteur, au moyen d'une source de tension de batterie (Ubatt) pouvant être alimentée en tension alternative du réseau (UN). Un régulateur de puissance de wattage électronique numérique (EVG) monté en amont de la lampe fluorescente (LA) allume la lampe fluorescente (LA) et peut traiter à son entrée, aussi bien une tension alternative qu'une tension continue. Selon l'invention, l'élément lumineux de secours est monté en amont du régulateur de puissance de wattage électronique numérique (EVG) et dans ledit élément lumineux de secours (NLE) la tension continue de la source de tension de batterie (Ubatt) qui peut être chargée, est convertie par l'intermédiaire d'un convertisseur continu-continu (DC1/DC2) en une tension continue (DC2) plus élevée. Une unité de surveillance du réseau actionne des contacts de commutation (S1,S2) de manière qu'en cas de tension alternative de réseau, la sortie du régulateur de puissance de wattage électronique numérique (EVG) soit pilotée par la tension alternative de réseau (UN) et qu'en cas de panne de secteur, l'élément lumineux de secours (NLE) fournisse la tension continue au régulateur de puissance de wattage électronique numérique (EVG).
