Light assembly adapted to an umbrella shank

A light assembly comprising:

• a circular base having a circuit board mounted thereon, a battery on top of the circular base, a power switch on a side face of the circular base and electrically connected to the battery and the circuit board, a power socket electrically connected to the battery to provide electricity to the battery, light emitting diodes mounted on the circuit board and electrically connected to a controlling chip so that the controlling chip is able to control illumination of the light emitting diodes, a battery seat on top of the circular base to securely receive therein the battery and a U shaped passage defined through a side face of the circular base, wherein the U shaped passage communicates with ambient air;
• a circular rim mounted on a peripheral edge of the circular base;
• a transparent cover provided to securely engage with the circular rim to enclose the light emitting diodes;
• and
• a clamping mechanism securely mounted on two opposed sides of the U shaped passage and having two rubber cushions oppositely movable relative to each other so that when an umbrella shank is extended into the U shaped passage and located between the two rubber cushions, the umbrella shank is securely sandwiched and the light emitting diodes are able to provide illumination.
