Abstract

A solar-powered collapsible lighting apparatus includes a lighting element assembly having a lighting element, a solar cell, a battery unit, and a collapsible shade. The battery unit is electrically coupled to the solar cell and to the lighting element assembly. The solar cell is positioned proximate to the top of the collapsible shade. The lighting element assembly and the battery unit are positioned within the collapsible shade. The solar-powered collapsible lighting apparatus is deployed by connecting a support unit between a top portion and a bottom portion.

Claims

1. A solar-powered collapsible lighting apparatus comprising:

a lighting element assembly which comprises a lighting element;

a solar cell;

a battery unit electrically coupled to the solar cell and to the lighting element assembly; and

a collapsible shade which comprises an opening located at the top of the collapsible shade and an opening located at the bottom of the collapsible shade; and

a support unit which comprises a top portion that houses the solar cell and the battery unit, a bottom portion positioned within or proximate to the opening located at the bottom of the collapsible shade and a connecting device which connects the top portion of the support unit and the bottom portion of the support unit, wherein the top portion of the support unit is positioned within and at least partially below the opening located at top of the collapsible shade and the lighting element assembly is positioned within the collapsible shade when the collapsible shade is in both its collapsed state and its deployed state.

2. The lighting apparatus of claim 1 wherein the lighting element of the lighting element assembly is located between the bottom portion of the support unit and the top portion of the support unit and is separate from and electrically coupled to the solar cell.

3. The lighting apparatus of claim 1 wherein the top portion of the support unit houses the lighting element assembly, the solar cell and the battery unit.

4. The lighting apparatus of claim 1 further comprising a hanging device for hanging the lighting apparatus.

5. The lighting apparatus of claim 4 wherein the hanging device is a wire.

6. The lighting apparatus of claim 4 wherein the hanging is connected to the top portion of the support unit.

7. The lighting apparatus of claim 4 wherein the hanging device is a rounded metal handle.

8. The lighting apparatus of claim 4 wherein the collapsible shade comprises a collapsible material which allows the partial or complete transmission of light through it and a collapsible frame which imparts a predetermined shape to the collapsible material.

9. The lighting apparatus of claim 8 wherein the collapsible material is located over the collapsible frame.

10. The lighting apparatus of claim 8 wherein the collapsible frame is located within the collapsible material.

11. The lighting apparatus of claim 8 wherein the collapsible material is paper, nylon, fabric or plastic.

12. The lighting apparatus of claim 8 wherein the collapsible material is waterproof or water-resistant.

13. The lighting apparatus of claim 8 wherein the collapsible frame is wire or plastic.

14. The lighting apparatus of claim 8 wherein the predetermined shape is a globe.

15. The lighting apparatus of claim 1 wherein the solar cell comprises one or more solar panels.

16. The lighting apparatus of claim 1 wherein the battery comprises one or more rechargeable batteries.

17. The lighting apparatus of claim 1, further comprising:

a light sensor; and

a switch electrically interposed between the battery and lighting element assembly, the switch being electrically coupled to the light sensor to be selectively opened and closed thereby.

18. The lighting apparatus of claim 1 wherein the lighting element assembly further comprises a lighting element cover.

19. The lighting apparatus of claim 18 wherein the lighting element cover focuses light from the lighting element.

20. The lighting apparatus of claim 18 wherein the lighting element cover filters light from the lighting element.

21. The lighting apparatus of claim 18 wherein the lighting element cover diffuses light from the lighting element assembly.

22. The lighting apparatus of claim 18 wherein the lighting element cover is cracked glass.

23. The lighting apparatus of claim 18 wherein the lighting element assembly further comprises a circuit board.

24. The lighting apparatus of claim 18, wherein the lighting element comprises one or more LED'"'"'s electrically coupled to the battery.

25. A method for assembling a solar-powered collapsible lighting apparatus comprising:

providing a collapsible shade that contains an opening located at the top of the collapsible shade and an opening located at the bottom of the collapsible shade in its collapsed state;

providing a support unit having a bottom portion, a connecting device and a top portion which houses a solar cell, a battery unit and a lighting element assembly, wherein the top portion of the support unit is positioned within and at least partially below the opening located at the top of the collapsible shade when the collapsible shade is in both its collapsed state and its deployed state;

providing a hanging device;

allowing the collapsible shade to expand to its deployed shape;

assembling the support unit by connecting the top portion to the bottom portion using the connecting device;

positioning the support unit within the deployed collapsible shade such that the top portion is positioned within or proximate to the opening located at the top of the collapsible shade and the bottom portion is positioned within or proximate to the opening located at the bottom of the collapsible shade; and

attaching the hanging device to the top portion of the support unit.
