FIELD: radio engineering, communication.
SUBSTANCE: methods and device for lighting device control, using the communication protocol, transmitted through the power supply line, that feeds the lighting device. The data can be transmitted to the plurality of lighting devices (4) by changing the output voltage, transmitted to the lighting device by switching the transformer (120), connected to the output voltage. The data can be received in the lighting device (40) through the reception of the encoded output voltage and comparison of output voltage sinusoidal cycle many periods voltage level to determine the incoming package data. One or more aspects of the lighting device (40) can be controlled on the basis of the received data.
EFFECT: increase of the communication signal transmission over the longer distance reliability.
