Abstract

LA PRESENTE INVENCION SE DIRIGE A UN DISPOSITIVO DE LASTRE ELECTRONICO PARA EL CONTROL DE LAMPARAS DE DESCARGA DE GAS. EL DISPOSITIVO CONSISTE EN UNA UNIDAD DE ALOJAMIENTO CON CIRCUITERIA ELECTRONICA Y COMPONENTES RELACIONADOS. EL DISPOSITIVO ACEPTA CORRIENTE ALTERNA Y LA RECTIFICA EN VARIAS TENSIONES DE CORRIENTE CONTINUA BAJAS PARA ACCIONAR LA CIRCUITERIA ELECTRONICA Y A UNA O MAS TENSIONES ALTAS DE CORRIENTE CONTINUA PARA ALIMENTAR CORRIENTE LAS LAMPARAS. TANTO LAS TENSIONES DE CORRIENTE CONTINUA BAJAS CON LAS TENSIONES DE CORRIENTE CONTINUA ALTAS PUEDEN SER ALIMENTADAS DIRECTAMENTE, ELIMINANDO LA NECESIDAD DE RECTIFICAR LA CORRIENTE ALTERNA. EL DISPOSITIVO CONMUTA UNA TENSION DE CORRIENTE CONTINUA DE MANERA QUE SE GENERE UNA SEÑAL DE FRECUENCIA. DEBIDO A LA ELECCION DE LOS TRANSFORMADORES DE SALIDA ADAPTADOS A LA ALTA FRECUENCIA (APROXIMADAMENTE (38KHZ) Y LA CAPACIDAD PARA CAMBIAR LA FRECUENCIA LIGERAMENTE PARA LLEVAR A CABO LA CORRIENTE PROPIA, EL DISPOSITIVO PUEDE ACEPTAR VARIOS TAMAÑOS DE LAMPARA SIN MODIFICACION. EL LASTRE PUEDE TAMBIEN OSCURECER LAS LAMPARAS AUMENTANDO LA FRECUENCIA. EL DISPOSITIVO PUEDE SER CONTROLADO A DISTANCIA.
