The invention discloses a waterproof LED lamp tube. The waterproof LED lamp tube comprises an LED light source, a heat sink, a lampshade, a lamp holder, a pin and a sealing rubber ring. The LED light source is connected to the heat sink in a clamped manner, and the heat sink is connected with the lampshade in a clamped manner; the lampshade is connected with the lamp holder in a clamped manner, and the pin is riveted on the lamp holder; the lamp holder is fixed to the heat sink through a screw; and the sealing rubber ring is fixed through deformation extrusion of the sealing rubber ring and the lampshade. The waterproof LED lamp tube has the advantages that the sealing rubber ring is stressed to deform and be extruded, so that the sealing rubber ring can effectively prevent moisture, damp and corrosive gas; and the LED light source can work in the more ideal and better environment, and the service life is greatly prolonged. Meanwhile, the diameter of the lamp holder is consistent with that of a whole lamp, and thus the lamp tube is suitable for more lamps.
