  • Linear solid-state lighting with an arc prevention switch mechanism free of fire and shock hazards
    Patent number: 9420663
    Abstract: A linear light-emitting diode (LED)-based solid-state universal lamp comprising integrated arc and shock prevention switches normally operates with either an electronic ballast or AC mains. When such a universal lamp is installed in or uninstalled from a linear tube lamp fixture, the integrated arc and shock prevention switches can work with an electronic ballast to prevent electric arc from occurring inside the lamp, thus eliminating any possible internal fire hazard while maintaining electric shock free for installers.
