Abstract
Balasto electrónico para el servicio de por lo menos una lámpara de descarga de gas, con una fuente (D) de tensión alterna, con un circuito (E) de carga, mandado por la fuente (D) de tensión alterna, que comprende por lo menos una lámpara (G1, G2) de descarga de gas y con un circuito de control (IC2) para controlar el servicio de la lámpara (G1, G2) de descarga de gas que supervisa una magnitud de circuito del balasto electrónico y, en función del valor de esta magnitud de circuito, durante el arranque del balasto electrónico, hace funcionar la lámpara (G1, G2) de descarga de gas con un modo de precalentamiento para precalentar los filamentos de la lámpara (G1, G2) de descarga de gas o sin este modo de precalentamiento, en el cual, como magnitud supervisada de circuito del balasto electrónico, el circuito de control (IC2) supervisa un potencial de tensión, aplicado en el circuito de control (IC2), que corresponde al estado de carga de un circuito de almacenamiento de energía (R22, C17), donde el circuito de almacenamiento de energía (R22, C17) se carga durante el servicio de la lámpara (G1, G2) de descarga de gas a un potencial de tensión de alimentación (VDD) predeterminado fijo y se descarga con una determinada constante de tiempo al desconectar el balasto electrónico.
