Abstract

Smart city is an attractive way of making the city more livable through intelligent solutions that are enabled by information and communication technology. Regarding the lighting system, it achieves the perfect balance between beautiful city ambience and preserving the darkness that makes cities more livable. As a smart city component, a public lighting system offers much more than light itself. Integration of other use cases has given a new dimension to the public lighting system in visual and functional terms. All those features that could be integrated into the public lighting infrastructure require additional power supply. This paper deals with possibilities of providing electricity to other power use cases integrated into the system of public lighting. Simulation results in DIALux showed that it is possible to save energy by a transition to LED lighting technology and establishment of a smart lighting management system using a dynamic operational profile proposed in the paper. By means of that, it is possible to reduce energy consumption in the public lighting system by at least 50 % up to 80 %, which could be enough for power use cases integrated into the public lighting infrastructure.
