Abstract: An exemplary embodiment of a solar-powered lighting fixture includes a solar panel electrically connected to a control circuit, a rechargeable battery to store electrical energy generated by the solar panel, and a LED module with a lens, wherein the lens has a plurality of integral optical elements comprising an inner refracting surface and an outer refracting surface, and the control circuit is capable of charging the battery by adjusting the charge current from the solar panel to the battery, automatically powering the at least one light-emitting diode on and off, and automatically adjusting the level and duration of electrical current provided to the at least one light-emitting diode. In at least one embodiment, the control circuit includes a microprocessor to calculate an operational profile based on the charge stored in the battery and an anticipated power requirement.
