ABSTRACT
Modern street lighting represents the pervasive utilization of light-emitting diode (LED) lamps to illuminate urban and rural areas. This chapter highlights the main features of LED public lighting systems that could be used for visible light communications (VLC). It provides a description of state-of-the-art street lighting, including its main functions, control systems, and typical parameters. The chapter discusses the recent studies on public lighting for VLC purposes, focusing on ray tracing simulations, noise parameters, and delay profiles among other topics. The lighting parameters which must be considered with regard to transport safety are related to motorized traffic, pedestrian walkways, and conflict areas. Light sources are technical devices used for transforming electric energy into optical radiation and, according to the type of energy transformation, electric light sources are divided into incandescent, discharge, and solid-state light sources. The purpose of the luminaires is to illuminate road surfaces and their immediate surroundings for the sake of motorists and pedestrians.
