Abstract
Dispositivo de alimentación, sobre dos niveles de potencia, para lámparas fluorescentes, que incluye al menos un circuito principal de alimentación, en el cual está inserta al menos una lámpara, conectada a una fuente de alimentación que asegura el funcionamiento de esta lámpara a su régimen nominal correspondiente a un nivel de iluminación máximo, caracterizado porque comprende un circuito electrónico auxiliar y un órgano de conexión de dos posiciones que aseguran la unión eléctrica entre los circuitos principal y auxiliar, asegurando éste entonces una derivación de corriente durante una parte de la alternancia que provoca un cambio de impedancia del circuito principal y un funcionamiento de la lámpara en régimen reducido, que corresponde a un nivel de iluminación mínimo cuando el órgano de conexión se encuentra en una primera posición, y la puesta fuera de circuito auxiliar cuando se encuentra en una segunda posición.
