Abstract
A lighting element for a solar powered lantern is formed integrally with a bottle closure which can be threaded onto a discarded plastic bottle, such that the light emitting diodes (LEDs) of the lighting element extend into the bottle. The lighting element is powered by a rechargeable battery which is recharged by a photovoltaic panel positioned on the top surface of the bottle closure.

A solar powered lantern, comprising:
- a translucent plastic base having a closed, bottom end, a top end, and a threaded opening at the top end;
- a threaded closure mating with the threaded opening at the top end and having a flat top surface and a photovoltaic panel arranged on the top surface;
- a rechargeable battery arranged on a side of the closure opposite the photovoltaic panel and connected to the photovoltaic panel;
- and
- an elongated lighting element connected to the rechargeable battery arranged on a side of the closure opposite the photovoltaic panel and comprising an array of light emitting diodes (LEDs) extending away from the top surface of the closure into the base,
- wherein the elongated lighting element includes an LED array mounted on opposite sides of a printed circuit board, housed within an optical tube sealed to the cap, and
- wherein the rechargeable battery is received in a cut-out in the printed circuit board.
