Abstract
La presente invención se refiere a un circuito de atenuación para dispositivos de iluminación, caracterizado porque comprende: un par de rectificadores controlados de silicio conectados en relación de circuito paralelo opuesto, teniendo cada rectificador controlado de silicio (SCR) un electrodo de control; un generador de señal para el control de fase, conectado al electrodo de control de cada SCR para conmutar el encendido y el apagado del SCR; una fuente de energía eléctrica conectada a la entrada del circuito de atenuación; inductores conectados en una relación de circuitos en serie con la fuente de energía y el par de SCR; y controladores del generador de la señal de manera que uno o ambos de los rectificadores controlados de silicio se enciendan y apaguen por medio de impulsos desde el generador que tiene una frecuencia de línea normal y una duración de impulsos predeterminada para controlar la intensidad de la luz proporcionada por los dispositivos de iluminación y para suprimir el ruido acústico generado por los dispositivos de iluminación.
