Abstract

A curved LED tubular lamp is disclosed. The curved LED tubular lamp includes a curved lamp tube having two straight segments and a curve segment disposed between the two straight segments; at least one flexible substrate having a plurality of LEDs mounted thereon, and at least one positioning pillar formed on the inner surface of the curve segment of the curved lamp tube, wherein each of the two straight segments and the curve segment have LEDs disposed therein, and wherein the flexible substrate is disposed in at least the curve segment.

First claim

What is claimed is:

1. A curved LED tubular lamp, comprising:
a curved lamp tube having two straight segments, and a curved segment disposed between the two straight segments; and
a first light board and a second light board respectively disposed in each of the two straight segments;
wherein each of the first light board and second light board has a plurality of LEDs disposed thereon;
wherein the first light board and the second light board are separated into at least two segments;
wherein the first light board includes a first straight portion disposed in a first straight segment of the two straight segments of the curved lamp tube, and a first curved portion disposed in a first part of the curved segment of the curved lamp tube; and
wherein the second light board includes a second straight portion disposed in a second straight segment of the two straight segments of the curved lamp tube, and a second curved portion disposed in a second part of the curved segment of the curved lamp tube.

2. The curved LED tubular lamp of claim 1 , wherein the curved segment comprises a middle connecting segment used to visually connect the plurality of LEDs of the first light board and the second light board, and the middle connecting segment is separated into a first middle connecting segment and a second middle connecting segment, wherein the first middle connecting segment is part of the first light board, and the second middle connecting segment is part of the second light board.

3. The curved LED tubular lamp of claim 2 , wherein the length of the first light board is equal to the length of the second light board.

4. The curved LED tubular lamp of claim 1 , wherein the curved LED tubular lamp further comprises one or more driving circuits, disposed in one or both of the straight segments of the curved LED tubular lamp.

5. The curved LED tubular lamp of claim 1 , wherein the curved LED tubular lamp includes two straight tubes and a rear supporter disposed between the two straight tubes, the rear supporter including a first piece having a protruded edge extending along an edge of the first piece and a second piece having a trench extending along an edge of the second piece, wherein the protruded edge is inserted into the trench, providing tight assembly of the rear supporter.

6. The curved LED tubular lamp of claim 1 , wherein the second straight portion of the second light board is attached on an inner wall of the second straight segment of the two straight segments of the curved lamp tube, and the second curved portion is attached to the second part of the curved segment of the curved lamp tube.

7. The curved LED tubular lamp of claim 1 , wherein the first light board and the second light board are separated to have a gap between each of the at least two segments.

8. The curved LED tubular lamp of claim 1 , wherein an end of the first curved portion faces an end of the second curved portion.

9. The curved LED tubular lamp of claim 8 , wherein a gap is formed between the end of the first curved portion and the end of the second curved portion.

10. The curved LED tubular lamp of claim 1 , wherein:
the first curved portion is attached to the first part of the curved segment of the curved lamp tube; and
the second curved portion is attached to the second part of the curved segment of the curved lamp tube.

11. A curved LED tubular lamp, comprising:
a curved lamp tube having two straight segments, and a curved segment disposed between the two straight segments; and
a first light board and a second light board respectively disposed in each of the two straight segments;
wherein each of the first light board and second light board has a plurality of LEDs disposed thereon;
wherein the first light board and the second light board are two separate pieces;
wherein the first light board includes a first straight portion disposed in a first straight segment of the two straight segments of the curved lamp tube, and a first curved portion disposed in a first part of the curved segment of the curved lamp tube; and
wherein the second light board includes a second straight portion disposed in a second straight segment of the two straight segments of the curved lamp tube, and a second curved portion disposed in a second part of the curved segment of the curved lamp tube.

12. The curved LED tubular lamp of claim 11 , wherein the curved segment comprises a middle connecting segment used to visually connect the plurality of LEDs of the first light board and the second light board, and the middle connecting segment is separated into a first middle connecting segment and a second middle connecting segment, wherein the first middle connecting segment is part of the first light board, and the second middle connecting segment is part of the second light board.

13. The curved LED tubular lamp of claim 12 , wherein the length of the first light board is equal to the length of the second light board.

14. The curved LED tubular lamp of claim 11 , wherein the curved LED tubular lamp further comprises one or more driving circuits, disposed in one or both of the straight segments of the curved LED tubular lamp.

15. The curved LED tubular lamp of claim 11 , wherein the curved LED tubular lamp includes two straight tubes and a rear supporter disposed between the two straight tubes, the rear supporter including a first piece having a protruded edge extending along an edge of the first piece and a second piece having a trench extending along an edge of the second piece, wherein the protruded edge is inserted into the trench, providing tight assembly of the rear supporter.

16. The curved LED tubular lamp of claim 11 , wherein the second straight portion of the second light board is attached on an inner wall of the second straight segment of the two straight segments of the curved lamp tube, and the second curved portion is attached to the second part of the curved segment of the curved lamp tube.

17. The curved LED tubular lamp of claim 11 , wherein the first light board and the second light board are separated to have a gap, in the curved segment of the curved lamp tube, between the two pieces.

18. The curved LED tubular lamp of claim 11 , wherein an end of the first curved portion faces an end of the second curved portion.

19. The curved LED tubular lamp of claim 18 , wherein a gap is formed between the end of the first curved portion and the end of the second curved portion.

20. The curved LED tubular lamp of claim 11 , wherein:
the first curved portion is attached to the first part of the curved segment of the curved lamp tube; and
the second curved portion is attached to the second part of the curved segment of the curved lamp tube.
