Abstract

An inflatable solar-powered light is provided. The solar-powered light includes a bladder and a solar-powered light assembly disposed entirely within the bladder. The solar-powered light assembly includes a solar panel, a rechargeable battery in electrical communication with the solar panel, and at least one light-emitting diode in electrical communication with the rechargeable battery. The bladder is substantially transparent, flexible, inflatable, and collapsible.

Claims (31)

1. An expandable solar-powered light, comprising:

an expandable body comprising:

a flat first surface;

a second surface opposing the flat first surface;

a substantially transparent cover on the second surface; and

an inner volume defined between the flat first surface and the second surface;

wherein the second surface and the substantially transparent cover form a substantially waterproof envelope; and

a light assembly disposed within the substantially waterproof envelope, the light assembly comprising:

a solar panel positioned within the substantially waterproof envelope directed to face outside the expandable solar-powered light,

a circuit board connected to the solar panel,

a rechargeable battery in electrical communication with the solar panel, and

at least one light-emitting diode in electrical communication with the rechargeable battery, wherein the at least one light-emitting diode is positioned to direct light through the second surface into the inner volume of the expandable body and toward the flat first surface.

2. The expandable solar-powered light of claim 1 , wherein the flat first surface and the second surface each comprise a plastic sheet.

3. The expandable solar-powered light of claim 1 , further comprising a handle coupled to the second surface of the expandable body.

4. The expandable solar-powered light of claim 3 , wherein the handle includes a large hole for carrying.

5. The expandable solar-powered light of claim 3 , wherein the handle comprises a first end and a second end, the first end and the second end coupled to the second surface of the expandable body.

6. The expandable solar-powered light of claim 3 , wherein the handle is fixed in position relative to the expandable body.

7. The expandable solar-powered light of claim 1 , further comprising a mechanism for coupling the expandable body to a person or a structure.

8. The expandable solar-powered light of claim 7 , wherein the mechanism for coupling the expandable body to a person or a structure comprises a carabiner.

9. The expandable solar-powered light of claim 1 , wherein at least the second surface comprises a semi-transparent material to diffuse light and create an ambient light source.

10. The expandable solar-powered light of claim 9 , further comprising a switch to selectively introduce and prevent a flow of electricity from the rechargeable battery to the at least one light-emitting diode.

11. The expandable solar-powered light of claim 10 , wherein the switch is further configured to selectively regulate the flow of electricity from the rechargeable battery to the at least one light-emitting diode.

12. The expandable solar-powered light of claim 11 , wherein the switch comprises light settings including at least high, low, and off.

13. The expandable solar-powered light of claim 11 , wherein the switch controls an amount of light emitted by the expandable solar-powered light.

14. The expandable solar-powered light of claim 1 , wherein the expandable body has a first expanded state and a second collapsed state.

15. The expandable solar-powered light of claim 14 , wherein in the second collapsed state, the expandable body is secured in the second collapsed state using one of a snap or a hook-and-loop closure.

16. The expandable solar-powered light of claim 15 , wherein, in the second collapsed state, the expandable body is folded into a flat configuration.

17. The expandable solar-powered light of claim 16 , further comprising a valve positioned on an exterior portion of the expandable body, wherein the expandable body can be expanded or contracted by passing a fluid through the valve.

18. The expandable solar-powered light of claim 17 , wherein the valve is positioned on the flat first surface of the expandable body.

19. The expandable solar-powered light of claim 1 , wherein the expandable body is substantially transparent, flexible, and waterproof.

20. The expandable solar-powered light of claim 1 , wherein at least one of the flat first surface and the second surface is substantially transparent.
