Linear solid-state lighting with electric shock and arc prevention mechanisms free of fire and shock hazards

摘要

A linear light-emitting diode (LED)-based solid-state lamp comprising electric shock and arc prevention switches, thermal protection devices, and bi-pins at the opposite ends normally operates with either an electronic ballast or AC mains. When such a lamp is installed in or uninstalled from a lamp fixture with the bi-pins in lamp sockets, the electric shock and arc prevention switches with double controls can work with the electronic ballast to prevent an electric arc from occurring not only between the lamp sockets and the bi-pins but also between electrical contacts in the electric shock and arc prevention switches. Together with the thermal protection devices, the lamp eliminates any possible fire hazard associated with the electric arc while maintaining electric shock free for installers.
