Abstract

Un dispositivo de iluminación controlable puede utilizar un circuito de impedancia controlable para conducir una corriente de carga a través de una fuente de luz LED. El circuito de impedancia controlable puede ser acoplado en serie con un primer dispositivo de conmutación, el cual puede volverse conductor y no conductor a través de una señal modulada por ancho de pulso para ajustar una magnitud promedio de la corriente de carga. El dispositivo de iluminación controlable además puede comprender un circuito de bucle de control que incluye un segundo dispositivo de conmutación. El segundo dispositivo de conmutación puede volverse conductor y no conductor en coordinación con el primer dispositivo de conmutación para controlar cuándo una señal de retroalimentación es proporcionada al circuito de bucle de control y es utilizada para controlar la fuente de luz LED. El circuito de bucle de control puede diferenciarse por una constante de tiempo que es significativamente mayor que un periodo operativo de la corriente de carga.
