<p>A roller with light emitting diodes incorporated therein is provided to achieve an improved luminous efficiency by mounting a non-utility generator in sports articles with rollers like in-line skates. The roller includes a stator, a bobbin, a rotor with light emitting diodes, a roller frame, a bearing and a connector. Light emitting diodes of the rotor are arranged in a vertical direction with respect to a shaft pin through a ring-shaped or board type connector, to thereby achieve a three-dimensional luminous effect. The roller has a simplified structure through the improved arrangement of the connector and improved structure of magnet and bearing, to thereby achieve an improved work convenience and productivity.</p> |
