Abstract:
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, and comprises a power switch electrically connecting between said power supplying system and said solar energy supplying system to automatically switch said power supply from said solar energy supplying system to said power supplying system when said electrical energy stored in said solar energy collection unit is below a predetermined level, wherein said solar collection unit comprises a solar energy housing, haying at least one solar energy collection panel transversely extended on top of said solar energy housing for exposing towards sunlight, mounted on top of said supporting post, and a solar conversion circuitry which is disposed in said solar energy housing and is electrically connected between said solar energy collection panel and said solar battery unit for converting solar energy collected by said solar energy collection panel into electrical power which is then transmitted to said solar battery unit for storage, wherein said power supplying system further comprises an electric socket supported by said supporting post to electrically connect with said illumination system and a battery recharge housing receiving said rechargeable battery to detachably couple with said electric socket so as to electrically connect said rechargeable battery with said illumination system, wherein said electric socket, having at least a socket slot, is supported within said supporting post, wherein said battery recharge housing has at least a corresponding plugging head slidably inserted into said socket slot through said supporting post to electrically connect said rechargeable battery with said illumination system; wherein said power supplying system further comprises a locking hub for detachably locking said battery recharge housing at said supporting post, wherein said locking hub comprises a hub body having two securing slots and two engaging arms spacedly extended from said battery recharge housing to detachably insert into said securing slots respectively so as to lock up said battery recharge housing at said supporting post.
