The subject innovation can result in visual fun and interest to reflect the light that lights up the light-emitting device using the electric power generated by a rotational force of the wheel and at the same time the radiation mainly from the light emitting device and prevent accidents during night driving, which is located in the center that by the reflector of the light-emitting wheel a so that the reflection performed on the entire wheel, and a generator (40) offset from the center of rotation of the rotating plate 30, the rotating plate 30, which is installed on the hub 23, hwilchuk (25 ) and the sun gear 50 and the planetary gear (60) to simultaneously rotate and revolve around the sun gear 50 by the rotational force of the rotating plate 30 for rotating the rotor of the generator 40, which is fixed to the rim (21) a is provided toward the center from the inner peripheral surface is provided so as to cross between the plurality of light emitting devices (LEDr) (LEDb) for supplying received emit the power generated from the generator 40, the rotating plate 30 and the rim 21, the generator balsaengdoe from 40 And a power supply line 70 for passing the wire (Wn) (Wp) for supplying electric power to the light emitting element (LEDr) (LEDb), is installed on the hub 23 the center of the light emitting component (LEDr) (LEDb) It is comprised of a reflector 80 for reflecting the light radially emitted toward.
