Existing umbrella played a role in the protection of mankind from the rain. In addition to this fundamental function, Luminella is a competitive factor as LEDs on the surface of umbrella emit light and thus reducing the accidents. For this facility, piezoelectric size should be approximately 3X5cm as users have to be able to fold and open an umbrella. Piezoelectric should be also coated with materials like vinyl to make it water proof. In order to turn on the LED, 3V of voltage and 20mA of current are needed, so generating enough power would be the most important issue. Furthermore, insulating current from the users would be essential.
