Energy efficiency in urban public lighting: literature review of equipment and technologies ; Eficiencia energética en alumbrado público urbano: revisión bibliográfica de equipos y tecnologías ; Eficiência energética na iluminação pública urbana: revisão bibliográfica dos equipamentos e tecnologias

With the increase in population and the need for greater amounts of natural resources to meet all the world's energy demand, the search for sustainable use of these resources is essential. One way to achieve this is through energy efficiency. Thus, this paper presents and compares the main existing resources for improving energy efficiency in urban public lighting, through bibliographic and documentary research. At the same time, energy efficiency programs in Brazil and incentives promoted by government-related institutions are cited. Finally, current technologies are demonstrated with case studies that aim to promote the energy efficiency of urban street lighting, highlighting their advantages and disadvantages. As a result, it is identified that the most viable alternative for revitalizing the street lighting system is the retrofit of traditional lamps by LED lamps, as it is a feature with greater durability, lower power consumption and less need for network adaptations. electrical current. However, from retrofit with LED lamps, it is possible to deploy additional features and technologies that allow intelligent monitoring of the entire system, adding, in addition to greater energy savings, more safety for the population. ; Con el aumento de la población y la necesidad de mayores cantidades de recursos naturales para suplir toda la demanda mundial de energía, la búsqueda del uso sostenible de estos recursos es esencial. Una de las formas de lograr esto es a través de la eficiencia energética. Así, el presente trabajo presenta y compara los principales recursos existentes para mejorar la eficiencia energética en el alumbrado público urbano, a través de la investigación bibliográfica y documental. Al mismo tiempo, se mencionan los programas de eficiencia energética en Brasil y los incentivos promovidos por instituciones vinculadas al gobierno. Finalmente, las tecnologías actuales se demuestran con estudios de casos que tienen como objetivo promover la eficiencia energética del alumbrado público urbano, ...
