Avaliação de viabilidade técnica no uso de luminárias led em projetos de iluminação pública

Abstract

This paper exposes the technical analysis of the impacts caused by swapping luminaires commonly used in public lighting projects on predetermined spaces of the city of Fortaleza by LED luminaires. The main goal of this document is to propose the studies on the functioning of LED luminaires and on what is the economic and financial impacts that result from using this type of luminaires in projects of great importance for society, which are the revitalization of the Praça Portugal, the Coronel Miguel Dias Avenue lighting improvement and the work on the installation of the new roundabout of the Raul Barbosa Avenue. Aside from this analysis, a comparison between the areas affected by these improvements, which used LED luminaires instead of the traditional model previously existent, will be made while taking in consideration cost-benefit between both luminaire types, impact in quality on those specific places, cost of executing the projects, active power demand before and after the swapping, service life preview and maintenance needs, the payback, the Internal Rate of Return (IRR) expected and the final diagnostics of the studies by comparing total energy consumption.
