Abstract
A hand cranked energy efficient light has a housing which houses a dynamo and associated electronic control circuitry that allows a user to turn a crank to charge a battery or capacitor which provides the energy required to operate LED lights and a clock. To help conserve energy, the number of LED light energized as well as their intensity may be varied. In one embodiment, an adjustable arm is provided to allow positioning of the light. In another embodiment, a camping lantern is provided. In another embodiment, a radio or other electronic device is also built in.

A hand cranked energy efficient light having built in functions comprising:
- a housing;
- said housing adapted to contain a dynamo and associated electronic control circuitry;
- an electrical storage device in electrical communication with said electronic control circuitry whereby electricity generated by said dynamo is reversibly stored therein;
- a hand crank in mechanical communication with said dynamo whereby when said hand crank is rotated, electricity is generated;
- a light housing portion disposed on said housing;
- said light housing portion holding at least one light source;
- said light source being in electrical communication with said electrical control circuitry;
- a display disposed on a surface of said housing;
- said display being adapted to display information to a user;
- said display being in electrical communication with said electrical control circuitry;
- a light source disposed within said light holding portion;
- and
- said light source being in electrical communication with said electronic control circuitry.
