ILUMINAÇÃO PÚBLICA: eficientização das luminárias

Abstract

This work deals with the efficiency of the luminaires in public lighting, i.e., changing the luminaires, emphasizing specifically the cost benefits of LED lamps compared to the lamps that are currently in use. Initially approaching a panorama of public lighting in Brazil and moving on to concepts of lighting, luminotechnics and the types of lamps most commonly used. By presenting energetic, luminous and cost-benefit evidence about the efficiency of the luminaries of public lighting through the LED lamp in comparison with lamps such as mercury vapor, metal halide vapor and mixed lamps, it will be proven later with a project of the city of Varginha-MG, which is already 90% concluded, that the LED technology is the best solution for public lighting, aiming low energy consumption, illuminance and longer useful life in comparison with others in use, bearing in mind that it is the responsibility of the municipality the management of the lighting park of the city so that this technological innovation occurs.
