Abstract

La presente invención se refiere a una combinación para accionar una lámpara para obtener luminiscencia de la lámpara; una fuente de corriente para proporcionar una corriente y un voltaje directos; un conmutador que envía a la corriente directa a través de la lámpara fluorescente; y un circuito de control de corriente para mantener la corriente directa a la lámpara a un nivel fijo constante de magnitud que es independiente de los cambios de voltaje en la lámpara.
