Abstract

A portable device for generating and providing electricity is disclosed. The device includes one or more flat solar panels; one or more batteries arranged to be changed with electric power from the one or more flat solar panels; one or more lights arranged to be powered from the one or more batteries; one or more electric connectors arranged to receive electric power form the one or more batteries and to connect to combined power/data connections on portable electronic devices; and an expandable and collapsible housing holding the solar panels, batteries, and lights, and arranged to form a hollow inner volume when expanded and a flat panel when contracted.

Claims (21)

1. A solar-powered lamp, comprising:

a bottom portion;

a side wall connected at a first end of the lamp to the bottom portion, wherein the lamp is expandable and contractable by collapsing and expanding the side wall;

a top portion connected to the side wall at a second end of the lamp that is opposite the first end of the lamp;

an electronics assembly contained in a watertight enclosure of the top portion and having a solar panel, a rechargeable battery, a printed circuit board, one or more LEDs attached to the printed circuit board, and at least one button;

a power connector rigidly attached to the electronics assembly; and

an enclosure for the power connector that can be opened and closed by a user to access the power connector, wherein the enclosure is sealed watertight with a removable cap and the top portion when it is closed by the user,

wherein the at least one button is electronically connected to the printed circuit board and controls one or more functions of the electronics assembly.

2. The solar-powered lamp of claim 1 , wherein the power connector comprises a data/power connector that allows for data transfer, and

wherein the removable cap is connected to the top portion by a plastic hinge.

3. The solar-powered lamp of claim 2 , wherein the removable cap makes a circumferential seal about its periphery with a corresponding matching surface mounted to the top portion.

4. 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, and wherein the first and second portions of the handle include snap connectors for connecting to each other.

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

6. 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 is indicative of a present level of charge of the rechargeable battery.

7. The solar-powered lamp of claim 1 , wherein the bottom portion and the top portion are sealed at their edges to the side wall, and

wherein the bottom portion and the top portion are each defined by rigid outer edges.

8. The solar-powered lamp of claim 2 , wherein the power connector comprises a port attached to the printed circuit board and is arranged to provide power from the rechargeable battery to a device that is external to the lamp, provide power from a device that is external to the lamp, to the rechargeable battery, or both.

9. The solar-powered lamp of claim 8 , wherein the data/power connector is a USB connector.

10. The solar-powered lamp of claim 8 , wherein the data connector is arranged to pass only electrical power, and not data.

11. The solar-powered lamp of claim 1 , wherein outer peripheries of the bottom portion and the top portion match a shape of the side wall, and are sealed to the side wall around the outer peripheries.

12. The solar-powered lamp of claim 2 , where the power connector is a two-way connector that is arranged to permit charging of the rechargeable battery from a source external to the lamp and also charging of a source external to the lamp from the rechargeable battery.
