Abstract
A high-safety LED tube, comprising: a first side having a first electrode and a second electrode; a second side having a third electrode and a fourth electrode; a first impedance module coupled to the first side; a second impedance module coupled to the second side; a first energy sensor having a first terminal coupled to the first impedance module; a second energy sensor having a first terminal coupled to the second impedance module; an LED unit coupled to the first impedance module and the second impedance module; a switch coupled to the LED unit; and a state control module coupled to the switch; wherein, when the first energy sensor or the second energy sensor detects an energy flowing between the first electrode and the second electrode or between the third electrode and the fourth electrode, the state control module turns on the switch.
