Abstract
A light driver for shoe comprises a power source, a switch unit, a controller, and a plurality of LEDs. The power source is composed of a first battery and a second battery in serial arrangement to provide two kinds of levels for LEDs with different characteristics. The switch unit is connected to an input of the controller, and the LEDs are connected to an output of the controller. The controller receives a triggering signal from the switch unit and drives the LEDs to flash.
