iStreetLight (hereinafter ISLS) street lighting system according to the invention represents a new concept in urban infrastructure building which in addition to lighting has active interaction with the environment by collecting data via sensor array related to atmospheric conditions and traffic conditions. At the same time platform is using solar energy and / or kinetic energy of moving vehicles and transmit radio waves related to utility, navigation and value added services. ISL is a device in the form of standard street lamp with the pole, which is composed of a central microprocessor component iCore (1E), LED bulb (1 K), communication module (1C), sensor array module (1B), module for energy collection iHarvest (1G), battery (1 H) and module for utility and value added services broadcasting to the end users (1D). All components are electrically connected and packaged in one or more water resistant box. Each ISL in network communicates with central system iStreetHost (hereafter ISH) (2D) via wireless network (2B) and the Internet (2C) sending all gathered data and ISL status information. Central ISH system (2D) is performing collection, storage and processing of data received from the ISL network, estimates traffic and microclimate conditions in ISL network area. ISH (2D) estimation results and the data required for the additional service sends back to the interested users via ISL network by using ISL transmission module (1D) and provides them available to the internet users (2C). ISL is collecting energy from the environment by iHarvest module (1G), which is receiving solar panel (1A) output and / or energy output from devices based on electroactive polymers EAP (1L) collecting kinetic energy of moving vehicles. iHarvest module (1G) and is connected to the power distribution network via connection (1F). ISL uses energy from the distribution system only when the energy level in the battery (1H) is below the defined limit of sufficient power for ISL.
