It is another design of umbrella. The top has a LED comes with a small accumulator. Then the umbrellas achieve certain weight that will trigger the power switch to light LED. It means: the rain and wind more badly, the LED more shiner, this way can keep you safe and help you to look clearly in night. Note it: it’s not an example of turning energy of motion into electric energy. If it can collect the energy from energy of motion by rain like as “E-Cart”  or “Stone shines” that will be more perfect, certainly I don’t know whether it is worth doing.
Designer: Sang-Kyun Park
