Abstract

La presente invención se refiere a un controlador de lámpara que comprende un circuito atenuador para operar en respuesta a un voltaje de control de una fuente de voltaje de control, para controlar una fuente enregizadora de lámpara CA de alta frecuencia, de dicho controlador de lámpara y para así controlar la intensidad de la luz, dicho circuito atenuador comprende; un transformador de aislamiento que incluye primeros y segundos medios de embobinado acoplados, medios para aplicar una corriente de alta frecuencia de dichos controlador a dichos priemros medios de embobinado, terminales de entrada para conectar a dicha fuente de voltaje de control, medios de carga que se acoplan con dichos segundos medios de embobinado y con dichas terminales de entrada y que se arreglan para limitar el voltaje que cruzan dichos segundos medios de embobinado, como una función de dicho voltaje de control y para así limitar el voltaje de alta frecuencia que se desarolla a través de dichos medios de embobinado primario a partir de dicha corriente de alta frecuencia y medios de dtención y salida para desarrollar y aplicar a dicho controlador una señal de salida, para el control de la intensidad de la lámpara, que corresponde al voltaje de lata frecuencia desarrollada a través de dichos medios de embobinado primario, dichos medios de carga incluye medios de amplificación y se arreglan de manera tal que respondan a una pequña corriente de control a través de dicha fuente de voltaje, para producir corrientes de carga amplificadas y sustancialmente iguales en dichos medios de embobinados secundarios, en ambos semi-ciclos de dicha corriente de alta frecuencia que se amplifica a dichos medios de embobinado primario.
