Abstract

L'invention concerne un dispositif d'éclairage de lampe fluorescente haute fréquence réglable en luminosité comprenant une source d'alimentation (1) réglable en fréquence, une lampe fluorescente (2) composée d'un tube (3) de lampe et d'éléments de circuit coordonnés, ces derniers comprenant une bobine d'induction (L), un condensateur (C) et un thermistor (RT). Une borne de la bobine d'induction (L) est reliée à l'une des bornes de la source d'alimentation (1), l'autre borne étant reliée à un point terminal (a) de l'une des deux cathodes du tube (3) de lampe. Le condensateur (C) et le thermistor (RT), une fois reliés en parallèle, sont reliés à l'autre point terminal (b) de la cathode et à un point terminal (d) de l'autre cathode du tube (3) de lampe. La caractéristique importante de ce dispositif réside en particulier dans les éléments de circuit coordonnés considérablement simplifiés de la lampe fluorescente, qui permettent d'obtenir une fonction de modulation régulière de la luminosité. La source d'alimentation (1) et la lampe fluorescente (2) haute fréquence, deux produits indépendants, sont d'ordinaire utilisés en coordination et présentent l'avantage d'être peu coûteux, de volume compact et de fonctionnement fiable.
