V. Design Constraints
Existing umbrella has 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 sho
