Avaliação da conservação de energia elétrica na iluminação pública de Pato Branco

Abstract

This paper presents an evaluation of electricity conservation. The study was made in segments of Pato Branco street lighting system. Relevant points are discussed, which contributed to creation of the Electricity Conservation Program (PROCEL) and the indispensability of rational energy use. Also a brief retrospective on artificial lighting and its importance for humanity is presented as well as the beginnings of street lighting in Brazil. The basics of photometry, the main types of lamps and auxiliary equipment used in street lighting systems, and the LEDs are pointed out. The local illuminance level was inspected with the use of a light meter. The horizontal illuminance measuring grids were prepared based on normative NBR 5101 for street lighting system investigation. The values adopted for evaluation of the current system illuminance and uniformity for each type of road are the minimum required by normative. The equipments that make up the street lighting system the scenarios chosen for study and the measurement grids setting are described. The illuminance data is verified through DIALux® EVO 3.0 software simulation. In comparison with the current system, each one of the public lighting system chosen for study is proposed at least one possible solution to reduce electrical energy consumption.
