Abstract
Una disposición eléctrica perfeccionada que comprende al menos un tubo de descarga en gas y/o vapor, provisto de un electrodo pre calentable, y medios para encender y alimentar ese tubo de descarga, teniendo la disposición dos terminales de entrada que están interconectados por una disposición en serie del tubo o tubos de descarga y una reactancia de estabilización que incluye un condensador, estando previstos los terminales de entrada para conexión a una fuente de tensión alterna, cuyo valor de tensión eficaz en voltios está comprendido entre 0,65 VB y 1,4 VB, donde VB es la tensión de arco total en voltio del tubo o tubos de descarga previstos en la disposición en serie y en donde el extremo del electrodo pre calentable alejado de los terminales de entrada está conectado a otro electrodo de tubo ( que está incluido en la disposición en serie ) a través de un circuito que comprende un elemento semiconductor de conmutación, y, en el estado de funcionamiento del tubo de descarga, este elemento de conmutación es activado al estado de conducción por un circuito de control en la segunda mitad de cada semi ciclo de la fuente de alimentación, caracterizado porque los dos electrodos están también interconectados a través de un elemento de circuito no lineal , teniendo dicho elemento, cuando la disposición está activada pero el tubo de descarga no se ha encendido aún, un valor óhmico inferior al que tiene en el estado de funcionamiento del tubo de descarga.
