FIELD: electricity.
SUBSTANCE: system comprises the following: control device (1) and lamp (3, 11). At the other side control device (1) is connected to phase conductor (L) of the feed voltage source (9) while lamp (3, 11) at the other side is connected neutral conductor (N) of the feed voltage source (9). Lamp (3, 11) comprises load (4) regulated in regard to its power, feedback regulator (7), feedback switch (5) and current-measuring resistor (6). Load (4) comprises decoder to analyze the received datagram (DT), control circuit, power link and illumination device. The regulator (7) monitoring circuit monitors continuously voltage in the load line (L') with a view to power line disturbances (ST), upon their detection regulator (7) re-switches feedback switch (5) and in result current short circuiting load (4) is set by current-measuring resistor (6) and feedback switch (5) resulting in short-term pulse increase (Kl) of current in load line, which is detected by short circuit protection of control device (1), whereupon repeated transmission of distorted datagram (DT) is initiated.
EFFECT: higher reliability of transmission.
