Abstract
A LED tube (41) comprises one or more LED components (34) and a current control unit (33) installed therein. Both ends of the LED tube (41) are provided with a contact pin pair (37, 38, 39, 40) for connecting the LED tube mechanically and electrically to tube holders of a fluorescent tube lighting fixture. The LED tube includes a safety unit (42, 43, S1) arranged to prevent a voltage from passing through the LED tube (41) from its one end to the other end thereof until at both ends of the LED tube, a voltage (U1, U2) fed from the corresponding tube holder of the lighting fixture to the contact pin pair (37, 38, 39, 40) has been detected separately.
