US Patent 7179181 Illuminating ball

An illuminating ball has embedded with a power supply device. Multiple output wires extending from the power supply device are electrically connected to multiple light emitting elements mounted over the ball. When the ball experiences vibration, a vibration-triggered switch in the power supply device can be automatically conducted to actuate the light emitting elements. On the contrary, the vibrating-triggered switch is automatically turned off if the ball is in the static status. Further, these light emitting elements also can be manually activated by controlling a switch.
