The paper presents a case study which advocates for the adoption of smart outdoor illumination installations that come with energy management systems. To analyse the energy efficiency we carried out measurements on: a) a classical outdoor lighting system, with sodium vapour sources, b) the same system after the sodium vapour light sources were replaced with LEDs, and c) the same system with LEDs augmented with an energy management system. Our analysis shows that replacing the outdoor light-sources with LEDs, in combination with an energy management system, results in a reduction of 40% in energy consumption. At the same time, the luminance coefficients of the LED lighting system are significantly higher than the luminance coefficients of sodium vapour sources.

Keywords: illumination, LED, management system, electric energy reduction.
