- Umbrellas have been used by us to shelter from the rain or sunlight. Illuminating umbrellas have also been designed to provide illumination for the convenience of night activities or serving as outdoor decoration or attracting automobile drivers' attention to the pedestrians, particularly in the raining nights.
- However, the conventional illuminating umbrellas are always powered by batteries received therein, whereby the umbrellas require a power outlet or an extension cord to get the electrical power supply.
- What is needed, therefore, is an illuminating umbrella which can overcome the above-mentioned problems.
- Many aspects of the present umbrella can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present illuminating umbrella. Moreover, in the drawing, like reference numerals designate corresponding parts throughout the several views.
