Abstract

A method for installing a LED light bar into a light bulb. First, place a light module into bulb shell. The light bar module has a plurality of LED light bars and expansion structure. The expansion structure is unexpanded and disposed between the plurality of LED light bars. Each LED light bar has a certain bending property. Expending the expansion structure could make the plurality of LED light bars bent to the direction of bulb shell individually. And then, remove the expansion module and install the other components of the bulb.

Claims

1. A method for installing a LED light bar into a light bulb, comprising:

placing the expansion structure into the light module;

placing the light module into the bulb shell, wherein said light bar module having a plurality of LED light bars, unexpanded and disposed between the plurality of LED light bars, each LED light bar having a certain bending property;

expending the expansion structure to make said the plurality of LED light bars bent to the direction of bulb shell individually;

reducing said expansion structure;

separating said expansion structure from said light module; and

mounting the other elements.

2. The method of claim 1, wherein said expansion structure is a balloon, and inflated said balloon to expand said expansion structure, and exhausted said balloon to reduce said expansion structure.

3. The method of claim 1, wherein said every LED light bar has two or more light bar sections, and a partitioned portion located between said light bar sections, said plurality of LED light bars bent at said partitioned portion when said expansion structure deformed against said light bar module.

4. The method of claim 3, wherein said partitioned portion can maintain its original shape in the absence of force.

5. The method of claim 1, wherein the substrate of said every LED light bar is a flexible circuit board, and bent under a certain external force, but maintained the shape at that time after the external force removed.

6. The method of claim 1, further comprising gluing at a predetermined position of said LED light bar, and then glued said bulb shell when said LED light bar against said bulb shell by said expansion structure, so a fixing effect is provided between said LED light bar and said bulb shell.

7. The method of claim 1, further comprising forming a corresponding clamping structure on said bulb shell and said LED light bar, when said bulb shell contacted to said LED light bar, said bulb shell and said LED light bar engaged with each other through said corresponding clamping structure.

8. The method of claim 1, wherein said mounting other elements includes mounting driving circuit to connect said light bar module.

9. The method of claim 1, wherein said plurality of LED light bars of the light bar module are connected at the top.

10. The method of claim 1, further comprising setting a cooling element on said LED light bar facing the back of the bulb shell.

11. The method of claim 1, further comprising mounting another light emitting module into said bulb shell, and surrounded by said plurality of LED light bars.

12. A lighting device, comprising;

a translucent shell;

a light bar module, mounted inside said translucent shell, said light bar module having a plurality of LED light bars, some of said the plurality of LED light bars expanded toward to the position near the inner edge of said translucent shell individually; and

a power supply circuit, connected to the light bar module to supply the power required by said light bar module.

13. The lighting device of claim 12, wherein said translucent shell is a bulb shell, wherein the power supply circuit includes a drive circuit connected to the light bar module, and further includes a bulb holder, having two electrical connection terminals for connecting external power to the drive circuit to drive the light bar module to generate illumination.

14. The lighting device of claim 13, wherein said LED light bar has two or more light bar sections, and a partitioned portion located between said light bar sections, said plurality of LED light bars capable of being individually expanded toward the position near the inner edge of the bulb shell and deformed when the plurality of LED light bars expanded outwardly by an expanding structure, and said plurality of LED light bars maintained the shape at the time when the expansion force removed.

15. The lighting device of claim 13, wherein the substrate of said every LED light bar is a flexible circuit board, and bent under a certain external force, but maintained the shape at that time after the external force removed.

16. The lighting device of claim 13, wherein said LED light bar is glued at a predetermined position, said LED light bar and said bulb shell are fixed through said glue.

17. The lighting device of claim 13, wherein said bulb shell and said LED light bar may have a corresponding clamping structures, and said bulb shell and said LED light bar are engaged with each other through said corresponding clamping structure.

18. The lighting device of claim 13, wherein said plurality of LED light bars of said light bar module are connected at the top.

19. The lighting device of claim 13, wherein said LED light bar is provided with a cooling element at a position facing the back of the bulb shell.

20. The lighting device of claim 13, further comprising another light emitting module located in said plurality of LED light bars.

21. The lighting device of claim 13, wherein said light bar module comprises two or more sub-light bar modules, and each sub-light bar module has a plurality of LED lights bars respectively.

22. The lighting device of claim 12, wherein said plurality of LED light bars are fixed on the base material layer.

23. The lighting device of claim 12, wherein said base material layer is a balloon, and said LED light bars move toward to the inner side of said translucent shell after said balloon inflated.

24. The lighting device of claim 12, wherein said base material layer includes a cooling material.

25. The lighting device of claim 12, wherein at least a portion of said LED light bars abuts to said translucent shell.
