Abstract
A wheel of a mobility scooter includes a wheel body provided with a light emitting module. The light emitting module includes an LED lamp bar, a plane mirror and a two-way mirror. The LED lamp bar is disposed between the plane and two-way mirrors. Mirror surfaces of the plane and two-way mirrors face the LED lamp bar therebetween. A perspective surface of the two-way mirror faces an outer side of the wheel. Through optical characteristics of the two-way mirror and the plane mirror, a real image of the LED lamp is reflected back and forth between the two mirrors for infinite times. From the perspective surface, a black hole illusion that LED lamps extend indefinitely into the wheel one after another can be seen, so that the interior of the wheel presents a hollow visual effect which is eye-catching, thereby increasing the product attractiveness and improving the market competitiveness.
