FIELD: electricity.
SUBSTANCE: invention relates to lighting control. Result is achieved by the fact that the controller of the LED node controlling the LED can determine whether the LED is activated in the active light emission state based on the activation probability of the LED. Thus, based on the activation probability of the LED, the LED at certain times may be in a state of active light emission and provide light output, and at other times it may be prohibited from being in a state of active light emission and it is forbidden to provide light output.
EFFECT: technical result is to ensure the prolongation of the life of the LED-based lighting device by controlling one or more light output properties of one or more LEDs of the LED assembly.
