Abstract

A light-emitting diode lighting tube includes a casing, an aluminum base board, which is fit into the casing and carries a plurality of light-emitting diodes, at least two reflective members respectively arranged on opposite sides of the light-emitting diodes, and first and second end caps respectively mounted to opposite ends of the casing. The casing has a radial cross-section forming an opening extending in an axial direction of the casing. The aluminum base board is fit to retention sections formed beside the opening. The two reflective members are arranged on opposite sides of the LEDs for reflecting lights emitting from the LEDs.

Claims

1. A light-emitting diode lighting tube, comprising:

a light-transmitting tubular casing, which has a radial cross-section forming an opening extending in an axial direction of the casing and forms retention sections on opposite side walls of the opening;

an aluminum base board, which carries a plurality of light-emitting diodes and is fit between the two retention sections;

at least two reflective members, which are respectively arranged on opposite sides of the light-emitting diodes to reflect lights emitting from the light-emitting diodes, an obtuse angle being formed between the two reflective members; and

first and second end caps, which are respectively mounted to opposite ends of the casing.

2. The light-emitting diode lighting tube according to claim 1, wherein the retention sections form opposite guide rails.

3. The light-emitting diode lighting tube according to claim 1, wherein the reflective members each selectively comprise a reflector board or a reflector film.

4. The light-emitting diode lighting tube according to claim 3, wherein the reflective members comprise reflector boards and wherein the casing comprises positioning sections provided respectively opposite to the two retention sections for positioning the reflective members.

5. The light-emitting diode lighting tube according to claim 4, wherein the positioning sections each selectively comprise a rib or a ditch.

6. The light-emitting diode lighting tube according to claim 3, wherein the reflective members comprise reflector films.

7. The light-emitting diode lighting tube according to claim 6, wherein the reflective members are set on an inner wall of the casing.

8. The light-emitting diode lighting tube according to claim 1, wherein the casing comprises a light diffusion section.

9. The light-emitting diode lighting tube according to claim 8, wherein the light diffusion section comprises a raised rib or a light diffusion film.

10. The light-emitting diode lighting tube according to claim 1, wherein the first and second end caps each comprise two tip-exposed terminal conductors and form an inner recess and also define holes extending therethrough.

11. The light-emitting diode lighting tube according to claim 1, wherein the first and second end caps comprises a support section formed on an inner side thereof and extending inward into the casing.

12. The light-emitting diode lighting tube according to claim 11, wherein the support section comprises a rectangular platform.
