BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a sunshade with an illuminating device for providing outdoor illumination.

2. Description of the Related Art

A sunshade for shielding people from sunlight is thus widely used in outdoor café and rest areas as well as on beaches.

An illuminating device is attached to a sunshade for the illumination purpose. The illuminating device needs a long-extended wiring connecting to an indoor socket or a generator for power supply. However, to use generator or long-extended wiring for supplying electricity in outdoor, some times brings big troubles.

Currently used conventional sunshade with illumination has a defect that due to a canopy post erects on the ground in the central position of sunshade, thus, the space for leisure activities and illumination is badly reduced. It is hard to place a main illuminating member in the central position of the direct illuminating area.

Thereby, to design a suitable sunshade in which the pole portion for supporting canopy is located beyond the canopy is required by people. This also is the unique feature of the present invention; it brings facilities for illumination and more space for leisure activities.
