Abstract
LA INVENCION TRATA DE LA INSTALACION DE UN CIRCUITO APROPIADO PARA HACER FUNCIONAR UNA LAMPARA DE DESCARGA DE MERCURIO A BAJA PRESION (IV) POR MEDIO DE UNA CORRIENTE DE PULSACION DE ALTA FRECUENCIA, QUE CONSTA DE: IENTE DE PULSACION DE ALTA FRECUENCIA CON UNA AMPLITUD A DE UN VOLTAJE DE SUMINISTRO, FORMA DE ONDA SUSTANCIALMENTE CUADRADA LA CORRIENTE DE PULSACION DE ALTA FRECUENCIA CON UNA FRECUENCIA DE MODULACION F Y UN CICLO DE FUNCIONES DC. SEGUN LA INVENCION, LA INSTALACION DEL CIRCUITO TAMBIEN CONSTA DE TUD A DE LA CORRIENTE DE PULSACION DE ALTA FRECUENCIA Y ONDA MODULADA DE FORMA SUSTANCIALMENTE CUADRADA. CON EL ULTIMO CIRCUITO ES POSIBLE HACER QUE EL PUNTO DE COLOR DE LA LAMPARA SEA ALTAMENTE INDEPENDIENTE DEL VALOR DEL FLUJO LUMINOSO. ADEMAS, ES POSIBLE AJUSTAR EL PUNTO DE COLOR DE LA LAMPARA CON UNA GAMA CONSIDERABLE, PARA UN FLUJO LUMINOSO DE LA LAMPARA DADO.
