Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lamp body device for a bicycle pedal and a bicycle capable of illuminating LEDs of the front and rear of the pedal in the respective same colors, regardless of right or left of the pedal, and regardless of which of treads a rider steps, with a more simple structure than ever.SOLUTION: A lamp body device for a bicycle pedal comprises: two lamp body parts arranged on both vertical sides of a pedal body rotatably supported by a pedal shaft of a bicycle, as well as arranged in two-fold symmetry with respect to the pedal shaft. Each of the lamp body parts comprises: a piezoelectric element generating electric power according to a pressure change; a first light emitting part illuminating in a first luminescent color by using the electric power generated by the piezoelectric element; and a second light emitting part illuminating in a second luminescent color different from the first luminescent color by using the electric power generated by the piezoelectric element, and emitting light toward a direction opposite to that of the first light emitting part.SELECTED DRAWING: Figure 1
