Evaluation of Maintenance and Modernization of Road Lighting Systems Using Energy Performance Indicators

This paper presents an assessment of the impact of maintenance of a road lighting luminaire with a high-pressure sodium lamp and an LED luminaire on the lighting parameters on the road and the energy efficiency of the entire road lighting installation. Improper maintenance of road lighting installations, especially of luminaires, can significantly worsen road traffic safety. In addition, after performing maintenance activities, e.g., after replacing a lamp in the luminaire, the energy consumption of the road lighting installation can increase. Both active and reactive energy can increase. Using the examples of a road luminaire with a high-pressure sodium lamp and an LED luminaire, it was shown that such a phenomenon can occur. An assessment of maintenance in terms of energy performance indicators was performed for the luminaire using the indicators described in the lightning standard and those proposed by the authors of this paper. This approach allows for a comprehensive assessment of maintenance on energy performance indicators—energy efficiency.
