FIELD: electricity.
SUBSTANCE: invention relates to lighting engineering. Illumination device (1) contains at least one light source (50) of low power; input power supply cascade (20) fit for receipt of low alternate voltage from an electronic transformer (ET); buffer power supply cascade (30) having input (31) connected to output (29) of the input power supply cascade; excitation circuit (40) intended for excitation of light and receipt of power supply from the buffer power supply cascade. The input power supply cascade generates output current pulses in order to charge the buffer power supply cascade at relatively low frequency, and during each output current pulse the input power supply cascade consumes input current, output current always has current value bigger than the required minimum load for the electronic transformer.
EFFECT: reducing light blinking by improving compatibility between light sources and electronic transformer.
