Abstract
La presente solicitud describe un circuito excitador para suministrar una corriente de excitación a un esquema de iluminación LED. En particular, la presente invención se relaciona con un circuito excitador de entrada de CA operable en conjunto con un dispositivo regulador de corriente que utiliza una pluralidad de diodos Zener conectados en combinaciones en paralelo. El circuito excitador comprende un mecanismo de retroalimentación que es operable para mantener un voltaje constante a través del regulador de corriente. Modalidades de la presente invención buscan abordar la ondulación de LED y, de esta manera, el parpadeo óptico que surge de un excitador de LED, conectado en su entrada, con una fuente de CA.
