A chapter in Energy Efficiency and Sustainable Lighting - a Bet for the Future from IntechOpen

Abstract: Improving the energy efficiency of road lighting is currently one of the most important issues. One of the methods of improving energy efficiency is the use of dimmable luminaires. In order to be able to compare the energy efficiency of different technical solutions, EN 13201-5 introduces energy performance indicators for road lighting installations. The chapter describes energy performance indicators for road installation and the impact of active power losses on these indicators and electricity costs. In order to accurately calculate the above indicators, the active power losses in the elements of the lighting installation should be taken into account. The chapter presents the dependencies which can be used to calculate the active power losses in single- and three-phase systems. In addition, an example of calculation of energy performance indicators, active power and energy losses and electricity costs is provided. The calculation was made for an exemplary installation of road lighting with dimmable luminaires. The analysis was done for single-phase and three-phase installations.
