FIELD: lighting.
SUBSTANCE: invention relates to lighting control systems. Disclosed is a system control of lighting installation comprising, made in form of a setting device, hidden wiring, control device, via connecting terminals is connected to phase wire of AC circuit and with loading wire, and an illumination unit, which via unit of connecting terminals is connected with neutral wire AC circuit and with loading wire, control device has a power part of control device, controlled by microcontroller control device and adjustment element, of loading microcontroller control device for setting brightness value, control device control signal corresponding to value of brightness, modulates network alternating voltage so that control device serves as a coder to brightness information, lighting unit comprises HF-PWM power section, controlled HF-PWM microcontroller and made in form of high-frequency pulse-width modulation generator connected to connecting terminals through LC-filter in series with lighting element, wherein HF-PWM microcontroller decodes control signal from output alternate voltage load wire and controls in accordance with HF-PWM load-carrying part.
EFFECT: technical result is optimisation of control of lighting installation without introduction of higher harmonics in supply mains.
