FIELD: lighting engineering.
SUBSTANCE: sequence of LED loads is powered by means of rectified voltage from the supply mains. Cathode of each LED load is grounded by means of the sequence. Sequences are made conducting and non-conducting one after another depending on the instantaneous value of rectified voltage from the power supply mains with the use of reading both voltage and current.
EFFECT: reduced flicker light and power dissipation.
