Abstract
LA INVENCION SE REFIERE A UNA INSTALACION DE CONMUTACION PARA ACCIONAR UNA LAMPARA DE SODIO DE ALTA PRESION (1) QUE IRRADIA LUZ BLANCA EN CONDICIONES ESTABLES DE OPERACION. EL DISPOSITIVO DE CONMUTACION TIENE ELEMENTOS CONMUTADORES (5) PARA CONMUTAR LA CORRIENTE A TRAVES DE LA LAMPARA POR MEDIO DE UNA SEÑAL DE CONDUCCION GENERADA EN UN CIRCUITO DE CONDUCCION (6), ESTA SEÑAL SE BASA EN UNA COMPARACION ENTRE UN VALOR DE REFERENCIA C Y UNA SEÑAL DE CONDUCCION V+(BETA)L, EN LA QUE V ES EL VOLTAJE DE LA LAMPARA, L ES LA CORRIENTE DE LA LAMPARA, Y (BETA) ES UNA CONSTANTE. SEGUN LA INVENCION, C PUEDE AJUSTARSE EN ETAPAS DEPENDIENDO DEL VOLTAJE DE LA LAMPARA. ASI EL PERIODO DE TIEMPO DURANTE EL CUAL LA LAMPARA IRRADIA LUZ BLANCA PUEDE PROLONGARSE Y AJUSTARSE A LA VIDA ELECTRICA DE LA LAMPARA.
