PURPOSE: Self-generating shoes are provided to be used for recognizing the location of a user during the night. CONSTITUTION: Self-generating shoes comprise a self-generating module unit(10) which comprises a piezoelectric element and outputs AC voltage according to external pressure, an electric wave rectifying unit(20) which rectifies the AC voltage of the self-generating module unit, a capacitor unit(30) which supplies stable DC voltage, a buck-boost convertor unit(50) which is discontinuously operated, a storage battery unit(60) which is charged with output voltage, a microcontroller unit(70) which outputs a pulse signal, and an LED drive circuit unit(80) which drives an LED. [Reference numerals] (40) Generating gate signal; (50) DC-DC charging; (70) Generating duty signal; (80) Constant current control |
