FIELD: electricity.
SUBSTANCE: invention is related to method and system for synchronous sinusoidal regulation of light fixtures luminance. The system for light fixtures dimming comprises the three-output light dimming module. The dimming module comprises a power controller and a receiver and responses to commands to regulate luminance received by the receiver. The power controller controls the step-down switch and freewheel switch so that reduction of alternating voltage is ensured.
EFFECT: maintenance of signal shape for supplied voltage and power coefficient of the light fixture.
