Abstract

An LED lamp tube is applied to satisfy a light source requirement and is used primarily to replace an existing conventional lamp tube, achieving an energy saving requirement. Plural LEDs are used as a luminous source which is assembled in a light permeable tube body, fitted with a drive circuit control module, so as to form the LED lamp tube. In addition, the LED lamp tube can be connected serially in plural sets depending on a length of the tube body, so as to comply with a light source requirement in various environments.

Claims

1. An LED (Light Emitting Diode) lamp tube which generates a light source after being energized by an electric current, comprising an LED module which is assembled by a circuit board and plural LEDs, two ends of the circuit board being assembled respectively with a first electric overlapping portion and a second electric overlapping portion and the first electric overlapping portion at one end being electrically connected with a drive circuit control module;

a tube body which is in a hollow shape and an inner annular surface of which is formed with more than one positioning rib, allowing the LED module and the drive circuit control module to be effectively positioned after insertion; and

two electric plug sets which are covered respectively at two ends of the tube body.

2. The LED lamp tube according to claim 1, wherein the second electric overlapping portion of the LED module is electrically connected with a first electric overlapping portion of another LED module.

3. The LED lamp tube according to claim 2, wherein a size of the tube body increases in multiples.

4. The LED lamp tube according to claim 1, wherein at least one of the two electric overlapping portions is a connector.

5. The LED lamp tube according to claim 1, wherein an outer annular surface close to two ends of the tube body is formed with more than one locking portion.

6. The LED lamp tube according to claim 5, wherein an inner annular surface of the electric plug set is formed with more than one locking point.

7. The LED lamp tube according to claim 1, wherein the LED module is assembled by a circuit and plural LEDs.

8. The LED lamp tube according to claim 1, wherein after inserting the LED module and the drive circuit control module into the tube body, a proper distance is formed between the two by the positioning ribs of the tube body.

9. The LED lamp tube according to claim 1, wherein the first electric overlapping portion is assembled at a bottom surface of the LED module.

10. The LED lamp tube according to claim 1, wherein the second electric overlapping portion is assembled at a bottom surface of the LED module.

11. The LED lamp tube according to claim 1, wherein the tube body is made by a PC (Polycarbonate) material permeating into a dispersant.
