Abstract

Se describe un circuito controlador que proporciona una corriente de accionamiento eléctrico a un esquema de iluminación LED. Particularmente, la presente se refiere a un circuito controlador de entrada de corriente alterna (CA) que funciona con un dispositivo regulador de corriente utilizando una pluralidad de diodos Zener conectados en paralelo. Comprende un mecanismo de retroalimentación que mantiene una tensión constante vía el regulador de corriente. Las modalidades de realización de la presente buscan abordar el problema del rizado del LED y del destello óptico que surge de un controlador LED, conectado en su salida, a una fuente de corriente alterna CA.
