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 ENCIA DE MODULACION F. CON EL ULTIMO CIRCUITO ES POSIBLE AJUSTAR EL PUNTO DE COLOR DE LA LAMPARA CON UNA GAMA CONSIDERABLE, MIENTRAS QUE EL FLUJO LUMINOSO PERMANECE PRACTICAMENTE CONSTANTE.
