Claims (3)

  1. Appareil pour faire fonctionner des sources lumineuses comprenant au moins une inductance sous la forme d'un produit enroulé constitué outre d'un enroulement ayant des extrémités (7, 8) de fils essentiellement de deux parties (1, 2) qui sont emboîtées l'une dans l'autre, et caractérisé en ce que
    - chacune des deux parties (1, 2) est fabriquée d'une manière continue en un matériau composite qui comporte de la ferrite et des polymères,
    - l'une des deux parties (1, 2) est en forme de pot ou de tube et il y est formé des rallonges sur lesquelles des extrémités (7, 8) de fils sont immobilisées,
    - et l'autre des parties (1, 2) est en forme de rouleau, et l'enroulement (3) y est appliqué.
  2. Appareil pour faire fonctionner des sources lumineuses comprenant au moins une inductance sous la forme d'un produit enroulé constitué outre d'un enroulement ayant des extrémités (7, 8) de fils essentiellement de deux parties (1, 2) qui sont emboîtées l'une dans l'autre, et caractérisé en ce que
    - chacune des deux parties (1, 2) est fabriquée d'une manière continue en un matériau composite qui comporte de la ferrite et des polymères,
