Abstract: FIELD: electrical engineering. 
     SUBSTANCE: invention relates to the field of electrical engineering, namely to illumination control systems, and is intended for cost-efficient autonomous illumination of residential, public, industrial areas, roads, including automobile roads, and other transport infrastructure objects. The proposed method for illumination of the territory of a spatially oriented object with modular light fixtures and an autonomous intelligent information illumination system for implementation thereof involves uniform distribution and installation of light fixtures on the territory of a spatially oriented object with connection thereof to the outdoor electrical lighting network; the following recording by each of the fixtures of complete information about the illumination area thereof depending on the time of day and the weather conditions, namely: illumination intensity thereof, fires, smoke generation and natural disasters, as well as incoming and/or outgoing moving objects; analysis of this recorded information and making an independent decision based thereon on establishing for the light fixture the illumination intensity of the illumination area thereof and the corresponding value of light intensity thereof and the following adjustment thereof in the fixture. Additionally, after each light fixture sets the illumination intensity level thereof requests to send information about the decisions made to set the illumination level of the illumination areas of other light fixtures and the corresponding values of the light intensity level thereof are formed in each of the fixtures, and after these requests are formed they are sent to other light fixtures located in the same activity radius and in response the requested information is received from these other light fixtures, analyzed by comparing the illumination level set in the illumination area of the light fixture and the corresponding level of the light intensity thereof with the received similar information from other light fixtures, and based thereon an independent decision is made on adjusting or leaving unchanged the illumination intensity in the illumination area of the light fixture, depending on the time of day and weather conditions, and adjusting or leaving unchanged the corresponding light intensity level of the light fixture. The previously set light intensity level of the light fixture is then adjusted or left unchanged and the response is sent to other light fixtures requesting information on adjusting or leaving unchanged the light intensity level in the illumination area of the light fixture, while all responses received from other light fixtures  located in the same communication signal range thereof are retransmitted, thus repeatedly interconnecting all the light fixtures within the same communication signal range, and thus forming one of local illumination networks interconnected multiple times from all the light fixtures located in the same communication signal range, wherein the network is part of a single self-regulated autonomous intelligent information illumination system that completely covers the entire territory from the first to the last light fixture, the viability and integrity whereof is constantly maintained by multiple overlapping with proportional relayed communication signals between the light fixtures of each formed local network.  
     EFFECT: accelerated decision-making on regulation of the light flow of each light fixture of the system by providing each of the light fixtures located within the same communication signal range with management functions in forming the local illumination network thereof, wherein the network is one of the parts of a single self-regulating autonomous intelligent information illumination system covering the entire territory from the first to the last light fixture, the viability and integrity whereof is constantly maintained by multiple overlapping with proportional relayed communication signals between the light fixtures thereof.
