The invention discloses an LED fluorescent lamp which comprises a lamp body and a drive power supply arranged on the lamp body to drive an LED. The lamp body comprises plugs for accommodating and fixing the drive power supply, the lamp body is a cavity consisting of a substrate and a lampshade, the plugs are sheathed at the two ends of the lamp body and provided with an electrode connected with the drive power supply and an external power supply, the lamp body is provided with an electric connection part and a power supply output part, the electric connection part is electrically connected with the LED, and the power supply output part is electrically connected with the drive power supply and pluggably connected with the electric connection part. As the electric connection part can be plugged with the power supply output part, only a new drive power supply provided with the power supply output part matched with the electric connection part needs to be exchanged when the old drive powersupply of the LED fluorescent lamp comes to the end or is damaged, therefore, the LED fluorescent lamp can work normally and another new LED fluorescent lamp needs not to be bought. In addition, an extension part of the plug is a cavity structure with an opening end, thereby being convenient for the placement of the drive power supply and the maintenance, and saving expenses and resources at thesame time.
