    Abstract: In order to ensure the normal and efficient operation of Light Emitting Diode (LED) and improve its drive circuit power factor,the paper designs a high-power factor LED constant current driving power supply based on L6561 power factor control chip and constant current diode. Experimental tests are carried out from three aspects of output voltage, load currents and power factor. According to the results,the constant voltage and constant current of this supply is great under the range of wide voltage, and its power factor is above 0.95,suppressing the current harmonic well.
    Key words: light emitting diode; high-power factor; constant current; driving power supply
