  • Patent number: 6290367
    Abstract: A rechargeable solar lantern with an improved power control circuit. The power control circuit includes a first switch, actuated by the connection of the solar panel to the battery, to prevent power from being supplied to the light bulb when the battery is charging. The power control circuit also includes a second switch to prevent power from being supplied to the light bulb when the voltage falls below a predetermined unacceptable level. Preferably, the second switch remains tripped until reset by the actuation of the first switch, indicating that the battery is being recharged.
