A BATON USING AFTER IMAGEEFFECT

摘要

PURPOSE: A baton using residual-image effect is provided to effectively achieve the function as a baton since the baton is well seen if a conductor conducts in the dark or wide place. CONSTITUTION: A baton using residual-image effect comprises a light emitting unit(110), a power supply unit, and a control module. The light emitting unit is formed in a manner a plurality of light emitting devices are arranged in a line at given intervals. The power supply unit supplies power to the light emitting unit. The control module is connected to the power supply unit and controls control signals to the light emitting unit so that conducting signs are seen by residual-image effect due to the spots of the light emitting devices when the light emitting unit moves to the left and right.
