Method and device for driving light-emitting diode by alternating current input voltage |
摘要 |
A method for driving a light-emitting diode based upon an AC input voltage includes receiving and full-wave rectifying the AC input voltage to generate a full-wave rectified input voltage, generating a pulse width modulation signal according to the full-wave rectified input voltage and a luminance signal, and generating a driving voltage according to the pulse width modulation signal and the full-wave rectified input voltage, and applying the driving voltage to the light-emitting diode.
