Summary:An LED driver circuit includes: a bridge rectifier, a first compensation capacitor, a second compensation capacitor, and an LED module. The bridge rectifier is connected to an AC input power for producing a rectification output power. The first compensation capacitor is connected to a first rectification output terminal and an AC input terminal of the bridge rectifier. The second compensation capacitor is connected to a second rectification terminal and the AC input terminal of the bridge rectifier. The LED module is connected to the first rectification output terminal and the second rectification output terminal of the bridge rectifier. The first and second compensation capacitors in the present invention can effectively improve the total current harmonic distortion of the LED module and its utilization.
