  • Patent number: 4939505
    Abstract: A system for failure detection of series-fed lighting circuits monitors the status of series-fed lamps and provides for feedthrough shift circuit protection of the isolating transformer and for suppression of overvoltage which appears at the failed lamp terminals. Current monitoring systems are rendered obsolete by this RLW (Runway Lighting Warning). The RLW system, which consists basically of a control unit equipped with detector probes, utilizes the series-fed lamp supply line, without any need for supplementary lines, and displays the failed lamp identification number accurately. The system has its preferred application in series-fed support lighting systems, but may also find application within any series-fed lighting system such as that of harbors, road networks and so on.
