FIELD: electricity.
SUBSTANCE: invention is referred to lighting devices and control of lighting devices operation. The result is obtained due to registration of the first and second values of phase angle for dimmer coupled to the power converter exciting load of solid-state lighting, at that the first, and second values correspond to in-series half-periods of line voltage input signal and difference between first and second value is defined. When this difference exceeds threshold difference specifying asymmetric waveform of the line voltage input signal, the selected corrective measure will be performed.
EFFECT: correction of misoperation and/or shutdown of power supply from load of solid-state lighting in order to eliminate undesired effects, such as twinkling.
