Abstract

Claims (34)

1. An expandable lamp, comprising:

an expandable bladder comprising:

a first surface; and

a second surface, the second surface opposed to the first surface, the expandable bladder having a collapsed state and an expanded state; and

an electronics assembly coupled to the first surface, the electronics assembly comprising:

a solar panel,

a circuit board,

a rechargeable battery electrically connected to the circuit board, and

at least one light-emitting diode (LED) configured to aim toward the second surface when the expandable bladder is in the expanded state; and

a substantially transparent cover portion configured to cover the solar panel at an exterior surface of the first surface, the substantially transparent cover portion being waterproof.

2. The expandable lamp of claim 1 , wherein the solar panel is positioned with respect to the first surface such that the at least one LED is located on an interior surface of the first surface and the solar panel is located on the exterior surface of the first surface.

3. The expandable lamp of claim 2 , wherein the LED is configured to direct light toward an interior surface of the second surface when the expandable bladder is in the expanded state.

4. The expandable lamp of claim 2 , wherein the expandable bladder is configured to be folded into a substantially rectangular shape when the expandable bladder is in the collapsed state.

5. The expandable lamp of claim 4 , further comprising at least one closure mechanism configured to retain the expandable bladder in the collapsed state.

6. The expandable lamp of claim 5 , wherein the at least one closure mechanism comprises straps with hook and loop portions.

7. The expandable lamp of claim 1 , further comprising a carabiner loop coupled to the expandable bladder.

8. The expandable lamp of claim 1 , wherein the expandable bladder further comprises a valve providing a valve passage through the first surface to an interior of the expandable bladder, the expandable bladder configured inflatable by a gas or liquid through the valve passage.

9. The expandable lamp of claim 8 , wherein the valve comprises a removable cover over the valve passage.

10. The expandable lamp of claim 1 , further comprising a power switch in electrical communication with the rechargeable battery and the at least one LED, wherein the power switch is configured to control an amount of light emitted by the LED.

11. An expandable lamp, comprising:

an expandable bladder comprising:

a first flexible surface; and

a second flexible surface, the second flexible surface opposed to the first flexible surface, the first and second flexible surfaces configured to have at least partially rounded shapes defined by first and second edges, respectively, and the expandable bladder having a collapsed state and an expanded state; and

an electronics assembly coupled to the first flexible surface, the electronics assembly comprising at least one light-emitting diode (LED) configured to aim toward the second flexible surface when the expandable bladder is in the expanded state;

wherein in the expanded state the first flexible surface is moved away from the second flexible surface such that the expandable bladder has a pillow-like rounded shape.

12. The expandable lamp of claim 11 , wherein the first flexible surface has a length from a first end to a second end greater than a width from a first side to a second side.

13. The expandable lamp of claim 11 , wherein the first flexible surface and the second flexible surface comprise polymeric materials.

14. The expandable lamp of claim 13 , wherein the polymeric materials are waterproof and flexible.

15. The expandable lamp of claim 14 , wherein at least one of the first flexible surface and the second flexible surface is configured to diffuse light from the LED.

16. The expandable lamp of claim 14 , wherein at least one of the first flexible surface and the second flexible surface comprise a semi-transparent material.

17. The expandable lamp of claim 14 , wherein at least one of the first flexible surface and the second flexible surface comprises a substantially transparent material.

18. The expandable lamp of claim 11 , the electronics assembly further comprising a power switch in communication with the at least one LED, the power switch configured to control an amount of light output by the at least one LED.

19. The expandable lamp of claim 11 , wherein the first flexible surface comprises a first panel defined by a first edge, and the second flexible surface comprises a second panel defined by a second edge, the second panel opposed to the first panel, the first panel sealed to the second panel at the first and second edges.

20. The expandable lamp of claim 11 , further comprising a carabiner loop coupled to the expandable bladder.
