This work presents an experimental investigation of the effects of aging on the photometric performance of public luminaires equipped with LED technology. Four commercial models with powers of 40W, 80W, 150W, and 200W were evaluated, subjected to standardized tests under controlled laboratory conditions. The tests followed the IES LM-80-15 standards and INMETRO regulations, and included photometric analyses, goniometric tests, UV radiation tests, and In-Situ thermal measurements (ISTMT). The results reveal significant variations in luminous flux, energy efficiency, and light quality over six thousand hours of simulated operation.
Optical degradation, especially of the lenses, showed a direct impact on the uniformity of light distribution. The study provides relevant technical support for the specification, acquisition, and maintenance of public luminaires, contributing to the increase of the lifespan and efficiency of the urban lighting system.
