Abstract:
A strip with multiple LEDs is installed on a wheel. When the wheel rotates, the LEDs are activated by a controller in accordance with stored image files, displaying the images. The LEDs may be multi-color devices, displaying the images in multiple colors. The image files may be downloaded over a wired or wireless connection. The controller monitors a sensor to determine angular positions of the LEDs in real time. The controller may vary the images in predetermined ways, or in response to commands received wirelessly from a control device. The LEDs may be powered by a generator driven by acceleration of the wheel, or by air movement in relation to the wheel. Multiple LED strips may be installed on a wheel to improve image appearance. Multiple wheels of the same vehicle may be equipped with LED strips. The images displayed on the wheels may be coordinated over a wireless interface.
