ESTUDO DE EFICIÊNCIA ENERGÉTICA EM ILUMINAÇÃO PÚBLICA COM TECNOLOGIA LED DIMERIZÁVEL INTEGRADO A SISTEMA DE TELEGESTÃO

Abstract

Given the growing demand for electrical energy and dependence on fossil fuels, recognized as finite sources and main emitters of polluting gases, it is becoming increasingly urgent to explore alternatives to reduce the use of natural resources, mitigate environmental impacts and promote better use. more rational use of electrical energy. In this context, the search for efficient solutions in electricity consumption is a pressing challenge. Considering the high electricity consumption bills for public lighting, solutions that can reduce these costs are extremely important for the municipality. The replacement of conventional lighting with LED technology is already a reality in many Brazilian municipalities, especially through federal government initiatives through electricity conservation programs aimed at this purpose. The efficiency of public lighting proves to be extremely advantageous, with great potential for reducing electrical energy consumption, in addition to improving the quality of lighting, providing better illuminance indices and color reproduction indices. Telemanagement systems appear as innovative elements in the urban scenario for the remote control of public lighting, dimming and system diagnosis. This dissertation proposed a study of energy efficiency in public lighting in the municipality of Jataí – GO. An analysis was carried out by replacing conventional technology with LED, where the savings generated and the costs of implementing the new luminaires were verified. Furthermore, a dimming proposal was evaluated for the highest consumption luminaires on public roads in the municipality, which still operate with sodium vapor luminaires in their lighting park. Although the results were satisfactory in energy terms, it is important to note that implementing the remote management system still involves a high acquisition cost.
