Light emitting pedal for bicycle

Abstract

The present invention relates to a light emitting pedal for a bicycle, wherein the light emitting pedal has been developed so that, when riding a bicycle, the rotating motion of a pedal body relative to a pedal shaft coupled to a crank arm is used to light up LEDs installed on the front and rear surfaces of the pedal body, thereby allowing easy discrimination from the surroundings. In the light emitting pedal for the bicycle, an electricity generating unit is provided in a pedal, which includes the pedal shaft mounted to a bicycle crank arm and the pedal body rotatably coupled to the pedal shaft, and causes an illumination part mounted on the pedal body to emit light. The electricity generating unit is characterized by comprising: a multi-pole magnet in which a plurality of magnets, which have a shape that is radially fragmented from a cylindrical shape and have inner and outer circumferences having different polarities, are bonded by an adhesive to a central portion that is inserted into the pedal body of the pedal shaft, and are mounted and fixed in a cylindrical shape in which different polarities are repeated along an outer circumferential surface; a pair of space portions formed symmetrically on both sides around the center through which the pedal shaft of the pedal body passes; a pair of mounting protrusions protruding into the space portions; a rotation shaft, of which both ends are rotatably mounted to the mounting protrusions; a rotation magnet mounted to the rotation shaft; a coil mounted along an inner edge of the space portions; and an LED light emitting unit connected to the coil and mounted to the front surface or the rear surface of the pedal body.
