<p><P>PROBLEM TO BE SOLVED: To provide a floating body that is changed in luminescent color every time a beach ball is hit, and also changed in color depending on, for example, a magnitude of an impact. <P>SOLUTION: The floating body including a swimming ring 1 for leisure and the beach ball which are used on water or the like comprises: a power supply composed of a chargeable battery 6; a first switch which is turned on when the floating body is thrown on water and contacts with a water surface and/or a second switch which is turned on when peripheral light reaches a constant value or lower; and a light emitting diode (LED) or a light emitter composed of an organic EL plate 4. When the floating body is thrown on the water in a status that the circumference is dark like night, the light emitter automatically emits light. Furthermore, by arranging an impact sensing sensor, a lighting interval or a lighting color of the light emitter is changed depending on an output of the sensor. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
