Power supplying system for outdoor umbrella
First Claim
1. An outdoor umbrella, comprising:
- an awning;
an umbrella frame comprising an upward supporting post, and an awning supporting frame which is detachably coupled with a top portion of said supporting post and is radially extended to support said awning to define a shading area thereunder;
an illumination system provided at said umbrella frame for illuminating said shading area of said awning;
a power supplying system, which comprises a rechargeable battery which is supported by said umbrella frame and is electrically connected with said illumination system for supplying electrical power to said illumination system; and
a solar energy supplying system, comprising;
a solar energy collection unit supported on top of said umbrella frame for collecting solar energy so as to transform said solar energy into an electrical energy;
a solar battery unit which is supported at said umbrella frame and is electrically connected between said solar energy collection unit and said illumination system, wherein said solar battery unit is adapted for storing said electrical energy from said solar energy collection unit in use for said illumination system; and
a powering control circuit electrically connecting said solar battery unit with said rechargeable battery to coordinate a power supply to said illumination system, wherein said powering control circuit selectively switches said power supply of said illumination system between said power supplying system and said solar energy supplying system for ensuring said illumination system obtaining sufficient power to provide optimal level of illumination.
