Richargeable portable light with multiple charging systems
First Claim
1. A rechargeable portable light, comprising:
- a housing member having an opening for the emission of light;
at least one charging means;
an electronic circuit for providing power for and control of the emission of light, said circuit located within said housing member, said circuit including at least one super capacitor for power storage, said super capacitor charged by said charging means, a voltage limiting circuit interposed between said super capacitor and said charging means, at least one light emitting diode (LED) positioned near the opening in said housing member, and a switch interposed between said capacitor and said LED, said switch being open when the capacitor is charging and closed when power is delivered from said capacitor to said at least one LED.

Abstract
A rechargeable portable light having a housing member with an opening for the emission of light, and several possible charging systems including a solar panel, an AC charger, an auto charger, and a hand crank generator charger. An electronic circuit is located within the housing member and includes at least one super capacitor for power storage. The super capacitor is charged by a charging system. A power inverter circuit, a mechanical switch method, or a DC-DC IC is used to increase voltage and regulate current. The circuit also includes at least one light emitting diode (LED) positioned near the opening in the housing member, and a switch interposed between the capacitor and the LED. The switch is closed when power is delivered from the capacitor to the LED.
