PURPOSE: A light emitting buoy is provided to stably receive power by using the power stored in a storage battery after being generated by a photovoltaic system and a wave power generation system. CONSTITUTION: A light emitting buoy comprises a ring-shaped tube(110), multiple light emitting elements(120), a photovoltaic part, a wave power generation part(140), a storage battery, a switching element, and a control part. The tube is waterproofed and floated in the water and is made by a transparent material. The light emitting elements are arranged in a row inside the tube and are electrically connected to each other. The photovoltaic part is installed on the water above the tube and generates power from sunlight with solar cells. The wave power generation part generates power applied to a coil(144) with the vertical movement of a permanent magnet due to waves. The storage battery charges power generated in the photovoltaic part and the wave power generation part. The switching element switches to make one of the photovoltaic part and the storage battery selectively supply the power to the light emitting elements. The control part controls the switching operation of the switching element. |
