Abstract

The provided bottom-lighting module comprises a bezel, a protrusion and at least one lamp. The bezel has at least one aperture with a first circumference and a second circumference. The bezel comprises a main body and at least one inclined wall extending upward from an edge of the main body. The protrusion is formed on the outer side of the bezel corresponding to the at least one aperture. Part of the circumference of the protrusion corresponds to the first circumference of the at least one aperture. At least one lamp is disposed on the main body of the bezel.

Claims

1. A bottom-lighting module, comprising:

a bezel having at least one aperture with a first circumference and a second circumference, the bezel comprising

a main body, and

at least one inclined wall extending upward from an edge of the main body;

a protrusion formed on the outer side of the bezel corresponding to the at least one aperture, wherein part of the circumference of the protrusion corresponds to the first circumference of the at least one aperture; and

at least one lamp disposed on the main body of the bezel.

2. The bottom-lighting module according to claim 1, further comprising a reflecting sheet disposed between the bezel and the at least one lamp.

3. The bottom-lighting module according to claim 1, wherein the aperture of the bezel ranges from about 0.01 mm to about 2.5 mm.

4. The bottom-lighting module according to claim 2, wherein the reflecting sheet has at least one aperture corresponding to the at least one aperture of the bezel.

5. The bottom-lighting module according to claim 4, wherein the aperture of the bezel is smaller than the aperture of the reflecting sheet.

6. The bottom-lighting module according to claim 5, wherein the aperture of the reflecting sheet is of a slit shape.

7. The bottom-lighting module according to claim 6, wherein the aperture of the reflecting sheet has a length ranging from about 1.5 mm to about 20 mm and a width ranging from about 0.01 mm to about 2.5 mm.

8. The bottom-lighting module according to claim 1, wherein the aperture of the bezel is formed at the main body.

9. The bottom-lighting module according to claim 1, wherein the aperture of the bezel is formed at the inclined wall.

10. A bottom-lighting module, comprising:

a bezel having at least one aperture with an orientation substantially perpendicular to the bezel, the bezel comprising

a main body, and

at least one inclined wall extending upward from an edge of the main body; and

at least one lamp disposed on the main body of the bezel.

11. The bottom-lighting module according to claim 10, further comprising a reflecting sheet disposed between the bezel and the at least one lamp.

12. The bottom-lighting module according to claim 11, wherein the reflecting sheet has at least one aperture corresponding to the at least one aperture of the bezel.

13. The bottom-lighting module according to claim 12, wherein the aperture of the bezel is smaller than the aperture of the reflecting sheet.

14. The bottom-lighting module according to claim 12, wherein the aperture of the reflecting sheet is of a slit shape.

15. The bottom-lighting module according to claim 14, wherein the aperture of the reflecting sheet has a length ranging from about 1.5 mm to about 20 mm and a width ranging from about 0.01 mm to about 2.5 mm.

16. The bottom-lighting module according to claim 10, wherein the aperture of the bezel is formed at the inclined wall.

17. The bottom-lighting module according to claim 10, wherein the aperture of the bezel is formed at the main body.
