Abstract
Light energy is to be utilized as the power source for a customary electrical equipment. A flexible photo-electric transducer 3 is arranged so as to be wound about a cylindrically-shaped winding core 2. When charging the storage battery 4, housed on the winding core 2, the photo-electric transducer 3 wound about the winding core 2 is pulled out to receive the light.
Claims12
A light charging type secondary battery unit comprising:
- a cylindrically-shaped winding core, and
- a flexible photo-electric transducer placed around said winding core so that the photo-electric transducer can be pulled out therefrom;
- said winding core including a secondary battery that can be charged and discharged, an a control circuit for controlling the charging and discharging of the secondary battery;
- said photo-electric transducer being wound on said winding core to present a substantially cylindrical overall shape.
