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 (43)

1. An expandable and contractable solar-powered light, comprising:

a bladder that defines an internal volume for receiving one or more of a gas, a liquid, or a solid, the internal volume having an internal surface, the bladder having a substantially transparent first panel, and a second panel that is positioned on an opposed side of the internal volume from the first panel, and a flat bottom panel that allows the solar-powered light to be positioned so as to stand in an upright position on the flat bottom panel; and

a solar-powered light assembly with a cover portion that is substantially waterproof from an area around the light assembly, wherein the light assembly is adjacent to the first panel and includes:

a solar panel attached to a circuit board,

a rechargeable battery to be charged by the solar panel, and

at least one light-emitting diode attached to the circuit board to be powered by the rechargeable battery and positioned to provide light into the internal volume of the bladder through the substantially transparent first panel,

wherein the circuit board is sealed between the cover portion and the first panel;

wherein the bladder is (a) substantially transparent, flexible, inflatable, and collapsible, and (b) capable of being contracted into a collapsed flat configuration,

wherein the cover portion, the first panel, or both have substantially transparent zones so as to permit sunlight to reach the solar panel and light from the at least one light-emitting diode to reach the internal volume, and

wherein the first panel, second panel, and circuit board lie flat adjacent each other when the bladder is in the collapsed flat configuration.

2. The light of claim 1 , wherein the solar-powered light assembly is a single-piece unitary structure comprising the circuit board, the solar panel, the rechargeable battery, and the at least one light-emitting diode.

3. The light of claim 1 , wherein the first panel and the second panel are each sealed along their outer peripheries.

4. The light of claim 1 , wherein the outer peripheries of the first panel and the second panel are rectangular in shape.

5. The light of claim 1 , where the outer periphery of the first panel is sealed to the outer periphery of the second panel.

6. An expandable and contractable solar-powered light, comprising:

a bladder that defines a first internal volume and having an internal surface defined at least in part by a first panel and a second panel that is positioned on an opposed side of the internal volume from the first panel, and a flat bottom panel that allows the solar-powered light to be positioned so as to stand in an upright position on the flat bottom panel; and

a solar-powered light assembly that is disposed in a second internal volume that is separated from the first internal volume, the second internal volume defined at least by a cover portion that is substantially waterproof and substantially transparent, wherein the light assembly is attached to the first panel and includes:

a solar panel attached to a circuit board,

a rechargeable battery connected to be charged by the solar panel, and

at least one light-emitting diode attached to the circuit board to be powered by the rechargeable battery and positioned to provide light into the internal volume of the bladder through the first panel;

wherein the bladder is (a) substantially transparent, flexible, expandable, and collapsible, and (b) capable of being contracted into a collapsed flat configuration,

wherein the solar-powered light assembly is sealed between the cover portion and the first panel,

wherein the cover portion, the first panel, or both have substantially transparent zones so as to permit sunlight to pass to the solar panel and light from the at least one light-emitting diode to pass to the internal volume, and

wherein the first panel, second panel, and circuit board lie flat adjacent each other when the bladder is in the collapsed flat configuration.

7. The light of claim 6 , wherein each of the solar panel, the rechargeable battery, and the at least one light-emitting diode is positioned on the circuit board.

8. The light of claim 6 , wherein the solar-powered light assembly comprises a plurality of light-emitting diodes.

9. The light of claim 8 , further comprising a valve arranged on an exterior portion of the bladder, whereby the bladder can be inflated or deflated via the valve.

10. The light of claim 6 , further comprising a power switch positioned on the circuit board and in electrical communication with the rechargeable battery and the light-emitting diodes, wherein the power switch is configured to control an amount of light emitted by the light.

11. The light of claim 10 , wherein the power switch is arranged to provide power to the at least one light-emitting diode so as to light the at least one light-emitting diode at multiple different powered lighting levels.

12. An inflatable solar-powered light, comprising:

a bladder defining a first volume, the first volume for receiving one or more of a gas, a liquid, or a solid; and

a solar-powered light assembly sealingly disposed within a second volume that is defined at least by a portion of the bladder and a substantially transparent sheet that covers the solar-powered light assembly, the solar-powered light assembly comprising a solar panel, a rechargeable battery to receive power from the solar panel, and at least one light-emitting diode to receive power from the rechargeable battery, and a circuit board connecting the solar panel, battery, and at least one light-emitting diode that is positioned to provide light into the first volume of the bladder through at least a portion of an exterior surface of the bladder, wherein the second volume is substantially waterproof, and wherein the second volume is separated from the first volume by at least a portion of the bladder;

wherein the bladder

is substantially transparent, flexible, inflatable, and collapsible,

is configured to diffuse light emitted from the at least one light-emitting diode, such that substantially the entire bladder is illuminated, and

has a first panel that holds the solar-powered light assembly and a second panel across the volume from the first panel and against which the at least one light-emitting diode is directed, a flat bottom panel that allows the solar-powered light assembly to be positioned so as to stand in an upright position on the flat bottom panel, and wherein the first panel, second panel and circuit board lie flat against each other when the light is in a collapsed configuration,

wherein the solar panel, rechargeable battery, circuit board, and at least one light-emitting diode are sealed between the substantially transparent sheet and the first panel.

13. The light of claim 12 , wherein the bladder comprises a plastic material.

14. The light of claim 12 , wherein each of the solar panel, the rechargeable battery, and the at least one light-emitting diode is positioned on the circuit board.

15. The light of claim 12 , wherein the solar-powered light assembly comprises a plurality of light-emitting diodes.

16. The light of claim 12 , further comprising a valve arranged on an exterior portion of the bladder, wherein the bladder can be inflated or deflated via the valve.

17. The light of claim 12 , further comprising a power switch in electrical communication with the rechargeable battery and the at least one light-emitting diode, wherein the power switch is configured to control an amount of light emitted by the light.

18. The light of claim 17 , wherein the power switch is positioned on the circuit board.
