Abstract
LA INVENCION EXPONE UN DISPOSITIVO DE CIRCUITO PARA OPERAR EN AL MENOS DOS LAMPARAS DE DESCARGA (LA1,LA2), QUE COMPRENDE: - UNOS TERMINALES DE ENTRADA (K1,K2) PARA LA CONEXION A UNA FUENTE DE ALIMENTACION DE VOLTAJE, - UNOS ELEMENTOS DE CONMUTACION (S1,S2) ACOPLADOS A LOS TERMINALES DE ENTRADA PARA GENERAR UN VOLTAJE DE ALTA FRECUENCIA DESDE UN SUMINISTRO DE VOLTAJE CONDUCIDO POR LA FUENTE DE ALIMENTACION DE VOLTAJE, - UN CIRCUITO DE CONTROL (SC) PARA GENERAR UNA SEÑAL DE ALTA FRECUENCIA PARA CONCEDER LA CONDUCCION O NO CONDUCCION DE LOS ELEMENTOS DE CONMUTACION A ALTA FRECUENCIA, - UN PRIMER TUBO DE CARGA (1) PROVISTO DE DOS EXTREMOS ACOPLADOS A LOS ELEMENTOS DE CONMUTACION CON UNOS PRIMEROS ELEMENTOS INDUCTIVOS (L1), CON UNOS PRIMEROS ELEMENTOS CAPACITIVOS (C1) Y CON TERMINALES (K3,K4) PARA ACOMODARLOS A UNA PRIMERA LAMPARA DE DESCARGA (LA1), - UN SEGUNDO TUBO DE CARGA (II) PROVISTO DE DOS EXTREMOS QUE SE CONECTAN A LOS EXTREMOS DEL PRIMER TUBO DE CARGA, CON UNOS SEGUNDOS ELEMENTOS INDUCTIVOS (L2), CON UNOS SEGUNDOS ELEMENTOS CAPACITIVOS (C2), Y CON TERMINALES (K5,K6) PARA ACOMODARLOS A UNA SEGUNDA LAMPARA DE DESCARGA (LA2). DE ACUERDO CON LA INVENCION, EL DISPOSITIVO DE CIRCUITO SE CARACTERIZA ADEMAS EN QUE LA FRECUENCIA DE RESONANCIA DEL PRIMER TUBO DE CARGA ES DIFERENTE DE LA FRECUENCIA DE RESONANCIA DEL SEGUNDO TUBO; EN QUE LA FRECUENCIA DEL VOLTAJE DE ALTA FRECUENCIA ES MAYOR QUE LA MENOR FRECUENCIA DE RESONANCIA Y MENOR QUE LA MAYOR FRECUENCIA DE RESONANCIA; Y EN QUE EL DISPOSITIVO DE CIRCUITO ESTA PROVISTO DE UNOS ELEMENTOS PARA AJUSTAR LA FRECUENCIA DEL VOLTAJE DE ALTA FRECUENCIA. SE CONSIGUE POR ELLO, QUE LA RELACION ENTRE LOS FLUJOS LUMINOSOS DE LAS LAMPARAS DE DESCARGA PUEDA CONTROLARSE DE FORMA SIMPLE.
