The LED fluorescent lamp tube breaks the LED light in the inside
If only the lamp is broken, the line is not damaged, the connection should still be bright, no change
The lamp tube of LED fluorescent lamp alone is ok, inside you should see an aluminium base board, above be full of patch small lamp bead.
If this is not bad, then look back, there should be a small power supply at the end of the aluminum plate, and the other end of the power supply is 220V. Another possibility is that lower-end LED products will be blocked (non-isolated). Is the aluminum substrate in addition to the SMT chip, also some electronics posted above, if the aluminum board intact, you also to the end, one 220 v mains interface on both ends
