<P>PROBLEM TO BE SOLVED: To provide a piezoelectric generator for converting a feeble rotational kinetic energy being obtained from the natural world efficiently into electric power, and to provide a light emitting device employing it. <P>SOLUTION: The piezoelectric generator comprises a guide 1 arranged in a rotator 17 in the rotational direction, piezoelectric elements 2 arranged at arbitrary positions on the guide 1, and an impact body 3 arranged between two piezoelectric elements 2 on the guide 1 to move freely as the rotator 17 rotates wherein the impact body 3 moves as the rotator 17 rotates to collide against the piezoelectric element 2 thus generating power and repeats power generation as the rotator 17 rotates. Furthermore, a windmill is fixed to the piezoelectric generator in order to generate power for lighting a light emitting body with wind force thus obtaining a delineater light. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
