Abstract

Un circuito (500) para activar lámparas de descarga de gas conectadas en serie desde una bobina secundaria (528) del transformador conectada en un primero (529A) y un segundo (529B) puntos respectivamente, con una primera (508) y una segunda (514) terminales de salida a través de las lámparas. Un capacitor (532) acopla el primer punto con una terminal de salida intermedia (512). El voltaje antes de encender, producido a través de la bobina secundaria, se aplica a través de una sola lámpara (506) para causar que se encienda. Después de encenderse, la corriente hacia la terminal de salida intermedia (512) es limitada por el capacitor (532), y las lámparas son activadas en serie. De esta manera, se reduce el voltaje que necesita producir a través de la bobina secundaria, para asegurar que se enciendan todas las lámparas. Alternativamente, las terminales de salida a través de las lámparas se puede conectar con puntos de la bobina secundaria más apartados que el primero y segundos puntos (Figura 6) o intermedios al primero y segundo puntos (Figuras 1 a 4).
