Abstract

This work deals with the viability analysis and photometric comparison between two different systems concepts for public lighting, hence the solid state lighting (SSL) employing high power LED luminaries with integrated electronic converters and the conventional high pressure sodium (HPS) lamp based luminaries along with electromagnetic ballasts. The study and comparison stem on the relative perception of the human eye to different light sources with different spectral distributions, devoting special attention to scotopic conditions of illumination. Photometric data of a SSL system being currently installed for the replacement of current HPS luminaries at the School of Engineering of the Federal University of Juiz de Fora is provided for the analysis and comparison.
