SUBSTANCE: invention relates to communication engineering and can be used in optical communication systems. A coded light source in an illumination system is activated using a remote control device. If light source identification is successful, said light source is sent a control message to at least partially turn off its light. The light input of the identified light source is therefore turned off, thereby reducing the probability of conflict of coded light from an already identified light source with identifiers contained in the coded light emitted by other light sources. When there is no more detectable coded light, the sensitivity of the remote control device can be raised until the coded light is detectable again. Additional light sources can then be identified and activated.
