摘要:
According to the present invention, provided is an LED driving circuit comprising: a first rectification module, connected to an alternating current power source, for full-wave rectifying an applied alternating current voltage and for supplying a first rectification voltage which has been full-wave rectified to an LED light emitting module as a first driving voltage; and a second driving voltage supply module, connected to the alternating current power source in parallel with the first rectification module, for full-wave rectifying an applied alternating current voltage to generate a second rectification voltage, for charging energy using the generated second rectification voltage at a charging section, and for supplying a second driving voltage to the LED light emitting module at a compensating section.
