Abstract

SE DESCRIBE UN APARATO DE CONEXION PREVIA PARA UNA LAMPARA DE DESCARGA DE GAS DE BAJA PRESION DE CORRIENTE ALTERNA EN UN AUTOMOVIL, CON UN CONVERTIDOR DE TENSION EJECUTADO COMO CONVERTIDOR DE FLUJO, CONTRA INTERVALO ACUMULADOR DE CORRIENTE. EL CONVERTIDOR DE TENSION POSEE UN TRANSFORMADOR, CUYOS DOS ARROLLAMIENTOS DEL LADO PRIMARIO MUESTRAN CANTIDADES DE ARROLLAMIENTO DIFERENTES. EL APARATO DE CONEXION PREVIA, DE ACUERDO CON LA INVENCION, EVITA DE FORMA REGULAR DE CIRCUITO Y DE MANERA ESPECIALMENTE SENCILLA Y DE COSTE ADECUADO, LA APARICION DE DISTRIBUCIONES DE DENSIDAD DE LUZ NO HOMOGENEAS EN LAMPARAS DE DESCARGA DE GAS DE BAJA PRESION DE CORRIENTE ALTERNA.A PREVIOUS CONNECTION DEVICE FOR A LOW PRESSURE LOW PRESSURE GAS LAMP IS DESCRIBED IN A CAR, WITH A VOLTAGE CONVERTER EXECUTED AS A FLOW CONVERTER, AGAINST CURRENT ACCUMULATOR INTERVAL. THE VOLTAGE CONVERTER HAS A TRANSFORMER, WHOSE TWO LEVELS OF THE PRIMARY SIDE SHOW DIFFERENT ROLLING AMOUNTS. THE PREVIOUS CONNECTION APPLIANCE, ACCORDING TO THE INVENTION, AVOID IN A REGULAR WAY OF CIRCUIT AND IN A SPECIFICALLY SIMPLE AND ADEQUATE COST, THE APPEARANCE OF DISTRIBUTIONS OF LIGHT DENSITY DOES NOT HOMOGENEAS IN LOW PRESSURE GAS LAMPS .
