A lighted In-Line skate wheel (5) improving the wheel's aesthetic appearance as well as assisting in the safety of the user, wherein the lighting is provided preferably by light emitting diodes (70) placed within the wheel itself, powered by either a battery (55, 60) or mini-generator (110) placed within an annular recess (20, 120) located within the interior of the wheel. The device automatically turns itself on and shuts itself off by way of a centrifugal switch (35) in the case of the power supply being a battery. When the wheels cease to rotate, the centrifugal switch (35) automatically creates an open circuit, thereby shutting off the light emitting diodes (70). If the power supply utilized is the mini-generator (110), the power supply will automatically cease with the cessation of the rotation of the wheel due to the halting of the rotation of a magnet (145) about a conducting coil (140). The mini-generator (110) is situated within an annular recess (120) within an aperture defined by a circular roller body (115). As the wheel rotates, a magnet (145) attached to the axle of the In-Line skate remains stationary whereas an electrical coil (145) which is firmly mounted within a hub (125) attached to the circular roller body (115) rotates, thereby causing the electrical coil (140) to rotate about the stationary magnet (145), thus creating an electric potential. |
