Abstract

Una unidad de iluminación incluye por lo menos dos canales de fuentes de luz, y un excitador para las fuentes de luz. El excitador incluye un convertidor de tensión de DC/DC y una disposición de control para controlar la corriente suministrada a por lo menos uno de los dos canales en respuesta a una señal de control producida por el convertidor de tensión de DC/DC. De manera provechosa, un bucle de retroalimentación controla un dispositivo de conmutación en el convertidor de tensión de DC/DC para mantener el nivel de iluminación producido por las fuentes de luz a un nivel deseado independientemente de los cambios en el voltaje de suministro y la carga.
