Abstract

Se proporciona un sistema de balasto de iluminación y un método para lámparas fluorescentes. El sistema y método utilizan un bucle de control de corriente de lámpara para controlar el nivel de luz de una lámpara fluorescente. El balasto incluye un detector de bucle abierto que reconoce un bucle de control de corriente abierto como una indicación de una condición de falla o riesgo, y provoca que el balasto emita un voltaje de lámpara seguro o no emita voltaje. La condición de falla o riesgo puede ser por ejemplo, un voltaje muy alto en la lámpara o una corriente muy baja a través de la lámpara. El balasto también incluye un circuito de desactivación que evita que el detector de bucle abierto se desconecte en momentos cuando se espera que el bucle esté abierto, tal como durante el encendido y reinicio de mantenimiento de la lámpara.
