Abstract

A solar-powered lamp is disclosed. The lamp includes a plurality of radiating extensions, each being formed from a plurality of flat panels that can fold relative to each other along lines between respective ones of the plurality of flat panels; and an electronics assembly, wherein the lamp is collapsible, and the flat panels for each of the radiating extensions fold relative to each other as the lamp is collapsed.

Claims

1. A solar-powered lamp, comprising:

a plurality of radiating extensions each radiating out from a central axis of the lamp when the lamp is in an expanded state, each extension being formed from a plurality of flat panels that are capable of folding relative to each other along lines between respective ones of the plurality of flat panels;

a flat bottom panel and a flat top panel, wherein the flat bottom panel and the flat top panel are positioned parallel to one another along an axis and are differently sized relative to one another; and

an electronics assembly contained in a watertight enclosure on the flat top panel and having, electrically interconnected, a solar panel, a rechargeable battery, a printed circuit board, and one or more LEDs arranged to direct light from inside the lamp and out through the flat panels of the plurality of radiating extensions,

wherein the lamp is collapsible along the axis, and the flat panels for each of the radiating elements fold relative to each other as the lamp is collapsed.

2. The solar-powered lamp of claim 1, wherein the lamp is capable of being remotely controlled by a portable wireless device executing an application for control of the lamp.

3. The solar-powered lamp of claim 2, wherein the portable wireless device is arranged to control multiple lamps in coordination with each other.

4. The solar-powered lamp of claim 1, wherein the lamp includes a power port for charging electronic devices from the battery of the lamp.

5. The solar-powered lamp of claim 4, further comprising a removable cap that seals water-tight over the power port.

6. The solar-powered lamp of claim 4, wherein the power port faces out of the lamp along a line that is perpendicular to a plane of the printed circuit board.

7. The solar-powered lamp of claim 4, wherein the power port faces out of the lamp along a line that is parallel to a plane of the printed circuit board.

8. The solar-powered lamp of claim 1, further comprising a handle having a first portion attached to a first part of the lamp and a second portion attached to a second part of the lamp on a side of the lamp opposed to where the first portion is attached.

9. The solar-powered lamp of claim 1, wherein the lamp defines a sealed inner volume and is inflatable and deflatable.

10. The solar-powered lamp of claim 1, wherein the lamp includes a plurality of charge indicator lights that, in response to a user input, light up a number of lights that indicates a present level of charge of the battery.

17. The solar-powered lamp of claim 1, wherein the flat bottom panel and the flat top panel are octagon-shaped.

18. The solar-powered lamp of claim 1, wherein each of the plurality of flat panels of the plurality of radiating extensions is trapezoid-shaped.

19. The solar-powered lamp of claim 1, wherein when the lamp is in a collapsed state, the plurality of flat panels of each of the radiating extensions folds in an accordion-like manner.

20. The solar-powered lamp of claim 1, wherein each of the plurality of radiating extensions is scored to form the plurality of flat panels.

11. A solar-powered lamp for generating and providing electricity, comprising:

one or more solar panels;

one or more batteries arranged to be charged with electric power from the one or more solar panels;

one or more light emitting devices (LEDs) arranged to be powered from the one or more batteries;

one or more electric connectors arranged to receive electric power from the one or more batteries and to connect to combined power/data connections on portable electronic devices that are separate from the lamp; and

an expandable and collapsible housing comprised of a flat bottom panel, a flat top panel, and a plurality of tapered elements that;

each radiate outward from a centerline of the device,

each have a plurality of flat walls,

are collapsible by folding the plurality of flat walls relative to each other along times between respective ones of the plurality of flat walls, and

are positioned to receive light from the one or more LEDs and pass the received light through the plurality of flat walls,

wherein the flat bottom panel and the flat top panel are positioned parallel to one another and are differently sized relative to one another.

12. The solar-powered lamp of claim 11, wherein the lamp is capable of being remotely controlled by a portable wireless device executing an application for control of the solar-powered lamp.

13. The solar-powered lamp of claim 11, further comprising a removable cap that seals water-tight over the one or more electrical connectors.

14. The solar-powered lamp of claim 11, wherein the one or more electrical connectors face out of the lamp along a line that is perpendicular to a plane of a printed circuit board that connects to the one or more flat solar panels and the one or more batteries.

15. The solar-powered lamp of claim 11, wherein the one or more electrical connectors face out of the lamp along a line that is parallel to a plane of a printed circuit board that connects to the one or more flat solar panels and the one or more batteries.

16. The solar-powered lamp of claim 11, wherein the lamp defines a sealed inner volume and is inflatable and deflatable.

21. The solar-powered lamp of claim 11, wherein each of the plurality of flat walls of the plurality of tapered elements is trapezoid-shaped.

22. The solar-powered lamp of claim 11, wherein when the lamp is in a collapsed state, the plurality of flat walls of each of the tapered elements folds in an accordion-like manner.
