Japanese Patent JP2522175
Kind Code:
Y2
Abstract:
A luminous float includes a float body, a resistance plate and a light-emitting device, and causes the light-emitting device to emit light by electricity generated by a dynamo through the relative motions of the float body and the resistance plate, which are caused by waves and tidal currents. In a preferred embodiment, a contractible and extensible bellows provided at the bottom of the float body is connected with the resistance plate through a connecting element. Furthermore, one end of a spring is coupled to an inner member of the float body, and the other end of the spring is coupled to the bottom of the bellows through a coupling means.
