Abstract
This paper will present an approach for reconstruction of street lighting system regarding energy efficiency. Today, most street lighting systems are based on gas discharge lamps. LED lighting is energy efficiency lighting, which consumes less energy than lighting based on gas discharge lamps but, initial investment is still high. Methodology described in this paper includes analysis of the existing street lighting and gives guidelines for selection of equivalent LED lighting instead of the non-efficient existing one. Methodology includes economic evaluation of investment and saving ratio. This approach shortens calculation time, especially luminance calculations, due to lighting classification (on streets and areas) in clusters. This approach is especially appropriate for great systems of street lighting (city areas, cities and so on.).
