Abstract

Se proporciona un circuito de carga variable para usarse con un atenuador. Una carga de bajo vataje tal como un LED se proporciona en serie con el atenuador y el circuito de carga variable se proporciona en paralelo con el LED. Los circuitos de carga variable tienen dos diferentes características de carga cuando el voltaje aplicado desde el atenuador está por debajo de un umbral, el circuito de carga variable presenta una carga fija y cuando el voltaje aplicado está arriba de un umbral, el circuito de carga variable presenta una carga variable de manera que actúa como un constante retorno de corriente. La carga variable se proporciona por una porción de carga secundaria que puede o no puede actuar en combinación con la carga fija y la porción de carga secundaria se conmuta dentro o fuera del circuito de carga variable por una porción del circuito disparador.
