Light emitting device for automobile wheel

A light emitting device for an automobile wheel, comprising:

• a fixed member fixed to a wheel of an automobile wheel;
• a rotor disposed on the fixed member, and generating a magnetic force while being rotated with the fixed member by rotations of the wheel;
• a rotating shaft protruding from the fixed member;
• a circuit board disposed on the rotating shaft;
• a weight eccentrically disposed on the circuit board so as to maintain a fixed state of the circuit board;
• a stator electrically connected to the circuit board, and generating electrical energy using the magnetic force generated by the rotor, while being fixed to the circuit board;
• a light emitting member electrically connected to the circuit board, and emitting light using the electrical energy generated by the stator;
• an idle rotation support body coupled to the rotating shaft, and having an end to which the circuit board is fixed so as not to rotate with the rotating shaft;
• an advertisement member fixed to the idle rotation support body so as to display advertisement contents;
• and
• an advertisement weight eccentrically disposed on the advertisement member so as to maintain the fixed state of the advertisement member,
• wherein the idle rotation support body has bearings disposed at the outsides of both ends thereof, and the circuit board and the advertisement member are installed through the respective bearings.
