Patent abstract
A toy, particularly an educational toy that has a light-emitting diode device attached thereto. Instead of a whole array of light-emitting diodes, the light-emitting diode device has only one or multiple cross rows of light-emitting diodes rotating about an axis. The light-emitting diode device is operative to generate a plurality of illumination patterns or images by selectively switching on/off the light-emitting diodes at a specific orientation. The light-emitting diode device further has a sound-generating device interactive with the light-emitting diodes. That is, the sound-generating device is operative to generate a sound to represent an audio form of the illumination patterns or images displayed by the light-emitting diodes.
