Iluminação esportiva: contexto atual e estudo de caso na FAEFID-UFJF

Abstract

A good lighting in sports venues is fundamental not only for the visibility of athletes and referees, but also as a determining factor for physical safety and technical performance during sports practice. In the Brazilian scenario, however, the absence of a specific and updated ABNT standard for this sector creates a technical vacuum, forcing the use of international guidelines and often resulting in obsolete systems or inadequate maintenance. This study critically analyzed the lighting system of the football field belonging to the Faculty of Physical Education and Sports (FAEFID) at the Federal University of Juiz de Fora (UFJF), with the objective of highlighting its deficiencies and discussing the Brazilian normative gap regarding sports lighting. The methodology involved surveying the infrastructure, in loco illuminance measurements at 88 points, and comparison with international guidelines (FIFA and CIE). The inspection revealed that only 24 of the 72 installed floodlights (33.33%) are operational, with the infrastructure in an advanced state of degradation. Measurements confirmed the precarious situation, indicating an average illuminance (Eavg) of 61.16 lux, a value drastically inferior to the 200 lux required by FIFA for training activities (Class I). Although the uniformity (Umin/avg) of 0.556 met the minimum (0.5), the low global illuminance compromises safety and performance. Comparison with DIALux simulations reinforced the influence of the real system’s depreciation. It is concluded that the system is in very poor condition and does not meet minimum safety requirements, reinforcing the urgent need for modernization to LED technology and highlighting the lack of an ABNT standard aimed at sports environments.
