Abstract

A lamp shade includes a frame bar and a plurality of fixing members. The frame bar includes a pair of wall bodies and a base connected between the wall bodies. Each wall body has an inner wall surface, and the inner wall surfaces are disposed facing each other. The fixing members are disposed at the wall bodies, and at least one fixing member is located on each inner wall surface.

Claims

1. A lamp shade, comprising:

a frame bar, comprising a first wall body and a second wall body and a base connected between the first and the second wall bodies, wherein each of the wall bodies has an inner wall surface, the inner wall surfaces are disposed facing each other, and the base has a bottom surface and a plurality of first openings in the bottom surface;

a plurality of fixing members, disposed at the first and the second wall bodies, wherein at least two fixing member are located on each inner wall surface; and

a pair of baffle plates, disposed on the bottom surface and located between the first and the second wall bodies, wherein the baffle plates protrudes from the bottom surface and respectively located at two opposite ends of the frame bar, the baffle plates are located beside the first openings;

wherein the fixing members, the baffle plates, and the frame bar are formed integrally.

2. The lamp shade according to claim 1, wherein the fixing members are elastically connected to the first and the second wall bodies.

3. The lamp shade according to claim 1, wherein each of the fixing members is a tabular body.

4. The lamp shade according to claim 1, wherein the fixing members all extend from the first and the second wall bodies towards the base.

5. The lamp shade according to claim 1, wherein each of the fixing members has a connecting end and a distal end opposite to the connecting end, the connecting ends are connected to the first and the second wall bodies, the distal ends neither contact the first and the second wall bodies nor contact the base, and a distance between the distal ends and the base is smaller than a distance between the connecting ends and the base.

6. The lamp shade according to claim 5, wherein at least one fixing member further has a bending portion configured between the connecting end and the distal end thereof, such that the fixing member bends towards the first and the second wall body where the fixing member is disposed.

7. The lamp shade according to claim 6, wherein a length from the bending portion to the connecting end of the fixing member is greater than a length from the bending portion to the distal end of the fixing member.

8. The lamp shade according to claim 6, wherein a length from the bending portion to the connecting end of the fixing member is smaller than a length from the bending portion to the distal end of the fixing member.

9. The lamp shade according to claim 5, wherein the lamp shade is capable of accommodating a light-emitting element and the light-emitting element is disposed between the wall bodies and located on the bottom surface.

10. The lamp shade according to claim 9, wherein the light-emitting element is a light bar, and the light bar comprises a circuit board and at least one light-emitting diode (LED) assembled on the circuit board.

11. The lamp shade according to claim 10, wherein the circuit board is disposed between the distal ends and the bottom surface of the base.

12. The lamp shade according to claim 9, wherein the lamp shade is capable of being assembled with a light source module body to form a light source module.

13. The lamp shade according to claim 12, wherein the light source module is an edge-type backlight module.

14. The lamp shade according to claim 1, wherein one fixing member located on the inner wall surface of the first wall body and one fixing member located on the inner wall surface of the second wall body are disposed facing each other.

15. The lamp shade according to claim 14, wherein all fixing members located on the inner wall surface of the first wall body and all fixing members located on the inner wall surface of the second wall body are respectively disposed facing each other.

16. The lamp shade according to claim 1, wherein all fixing members located on the inner wall surface of the first wall body and all fixing members located on the inner wall surface of the second are distributed in a staggered manner.

17. The lamp shade according to claim 1, wherein at least one wall body has at least one second opening, and the second opening exposes one fixing member.

18. The lamp shade according to claim 17, wherein each of the wall bodies has a plurality of second openings, and the second openings expose the fixing members.
