Considerations about LED Technology in Street Lighting Systems – Power Quality Analysis

Abstract

In recent years, the public lighting systems in Brazil received investments to expand people's access to this service and increase their quality. With the implementation of smart cities projects, roads lighting technology has also become intelligent. This paper presents a comparison of lighting systems with: sodium vapor lamp, LED (Light-emitting Diode) lamp and intelligent LED lamp (remotely controlled) covering aspects of luminous efficiency, energy efficiency and power quality. All tests were performed in an accredited laboratory in Brazil and the results serve to drive new implementations in this area of study.
