摘要

The illuminated float comprises metal foils (f1,f2), which are rolled together in the body (h) of the float to form an energy-extracting surface, where the energy required for illumination is obtained from the surrounding water as electrolyte. The generated high voltage is regulated to control a light emitting diode.
