Abstract
A linear light-emitting diode (LED)-based solid-state lamp having a double safety mechanism that comprises at least three shock protection switches, fully protects a person from possible electric shock during re-lamping or maintenance. One protection switch provided at each end of the lamp is able to cut off power when the associated end of the lamp is not inserted into the lamp socket. A third protection switch can be used to turn off the power from the AC main for additional shock protection.
