Abstract

EL PROCEDIMIENTO PARA EL ENCENDIDO DE UNA LAMPARA DE DESCARGA, ESPECIAL DEL GENERO DE LAS LAMPARAS DE ARCO O TUBO DE NEON, EN LA QUE DICHA LAMPARA ESTA MONTADA EN UN CIRCUITO RESONANTE SERIE QUE TIENE UNA BOBINA (19) Y UN CONDENSADOR (20), EN EL QUE LA LAMPARA (23) ESTA MONTADA EN SERIE CON LA BOBINA Y EN PARALELO CON EL CONDENSADOR, ESTE CIRCUITO RESONANTE ESTA EN LA DIAGONAL DE UN PUENTE A CUYOS BORNES SE PROPORCIONAN PULSOS DE TENSION PROPORCIONADOS POR UNA ALIMENTACION CON CORTE, CARACTERIZADA PORQUE SE HACE VARIAR LA FRECUENCIA DE CORTE DE LOS PULSOS DE ALIMENTACION EN UN RANGO DE FRECUENCIAS EXTENDIENDOSE ENTRE DOS VALORES EXTREMOS DETERMINADOS QUE RODEAN LA FRECUENCIA DE RESONANCIA DEL CIRCUITO O UNO DE SUS ARMONICOS SEGUN UNA LEY APROXIMADAMENTE LINEAL, CRECIENDO LUEGO DECRECIENDO RESPECTIVAMENTE CON UN PERIODO DE BARRIDO DE ESTE RANGO DETERMINADO, PARA AJUSTAR SIMULTANEAMENTE EL ANGULO DE PASO DE LOS PULSOS MIDIENDO LA RELACION DE LA DURACION DE ESTOS A SU PERIODO CON VALOR CONSTANTE Y LIMITADO DE TAL MODO QUE LA CORRIENTE PROPORCIONADA POR LA LAMPARA A CADA IMPULSO ESTE REDUCIDA SENSIBLEMENTE, TRAS EL ENCENDIDO DE LA LAMPARA GRACIAS A LA SOBRETENSION CREADA POR LA RESONANCIA DEL CIRCUITO CUANDO LA FRECUENCIA DE CORTE ES IGUAL A LA FRECUENCIA DE RESONANCIA O A UNA DE SUS ARMONICOS, EN DETECTAR EL PASO DE CORRIENTE EN LA LAMPARA PARA LLEVAR LA FRECUENCIA DE LOS PULSOS A UN VALOR NOTABLEMENTE INFERIOR A LA FRECUENCIA DE RESONANCIA, EL ANGULO DE PASO ESTANDO AL MISMO TIEMPO AUMENTADO A UN VALOR OPTIMO.
