Abstract

La invencion se refiere a un sistema para operar una lámpara que consta de mecanismos de codificacion para perturbar parte de un numero predeterminado de medios períodos del voltaje senoidal de abastecimiento, el numero de medios períodos forma un período de control, y el circuito de inductor autoregulador con terminales de entrada (1',2') acoplado a los mecanismos de codificacion para recibir el voltaje perturbado. El circuito de inductor autoregulador consta de los mecanismos (A, B, C, E) para generar una corriente de lámpara fuera del voltaje perturbado, mecanismos (G) acoplados a los mecanismos para generar una corriente de lámpara, para controlar la característica de operacion de la lámpara en dependencia de una señal de control, y mecanismos (I) de decodificacion para generar una señal de control que depende de la silueta del período de control. Las perturbaciones aplicadas por los mecanismos de codificacion cambian la amplitud del voltaje senoidal de abastecimiento unicamente de una parte de cada medio período perturbado del voltaje de abastecimiento, de esta forma previene el parpadeo de luz.
