Abstract:
1. An improved LED tube structure capable of changing an illumination direction, being characterized in: a transparent tube having a corresponding plug track disposed on an inner tube wall thereof, wherein the plug track is disposed on the inner wall of the transparent tube at a height that is approximate to or above a horizontal center line of the transparent tube and the plug track is adapted for an LED lamp strip to be plugged and positioned therein; a conductive terminal being formed of a metal through stamping and having a tandem piece disposed between two terminals thereof, wherein both the terminals have a plurality of protruding hooks disposed thereon; and a positioning enclosure having two terminal plugholes spaced apart disposed in the middle portion thereof, wherein the protruding hooks of the terminals hook into the wall of the terminal plugholes after insertion of the terminals of the conductive terminal, and the tandem piece of the conductive terminal is connected to the LED lamp strip through a transmission line, and wherein the positioning enclosure has, on an inner surface thereof, a circular groove corresponding to the tube wall and the plug track of the transparent tube and a plurality of sets of plug track grooves disposed at different angles for the plug track of the inner wall of the transparent tube to be selectively plugged therein, thereby achieving the objective of changing the illumination direction of the LED lamp strip of the LED tube.
