ABSTRACT:
A light-emitting control circuit and a wrist training ball using the same are described. The wrist training ball includes a light-emitting device. The light-emitting device includes an electricity generating circuit and a light-emitting control circuit. The electricity generating circuit generates electric power by rotational kinetic energy of the wrist training ball and outputs the electric power to the light-emitting control circuit. The light-emitting control circuit includes first and second light-emitting elements. According to a voltage value of a voltage output by the electricity generating circuit, the first light-emitting element is turned-on to emit red-light, or the second light-emitting element is turned-on to emit blue-light, which is mixed with the red-light into purple-light due to visual persistence phenomenon, or the first light-emitting element is turned-off to increase the voltage instantly to make the blue-light brighter, thereby producing different light emitting effects according to different rotational ranges of the wrist training ball.
