Tese (Doutorado em Engenharia Elétrica e da Computação) - Universidade Federal de Goiás, Goiânia, 2022.http://repositorio.bc.ufg.br/tede/handle/tede/12643This work develops an optimization methodology for the design of high power LED luminaires – HP-LED. The objective is to design a luminaire with optimized geometry and LED quantity. The solution to the problem must have an illuminance uniformity factor in the illuminated area according to standards established by regulations and adequate thermal management that guarantees luminous flux and lifetime within the nominal standards established by the HP-LED manufacturer. A computational model of the geometry of the HP-LED luminaire is used, in which thermal and optical analyzes are performed through simulators. Simulation and experimental results are presented for validation of the proposed study and from the results of the simulations a multi-objective evaluation function is developed in order to categorize potentially viable solutions. The optimized solution obtained proposes the design of a rectangular luminaire with an arrangement of 2 × 2 HP-LED with a temperature that reaches a maximum value of 73.9oC in steady state and an illuminance uniformity factor of 0.228 for individual lighting. The illuminance uniformity factor found for two adjacent lighting points on pedestrian paths is 0.5413, with minimum illuminance of 36.95lx, maximum illuminance of 93.65lx and average illuminance of 68.27lx. It is concluded that the metric developed in this proposal is capable of evaluating lighting criteria and nominal criteria of thermal limitation, even managing to classify different types of luminaires.Attribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Otimização lumináriaLight Emitting Diode (LED)Fator de uniformidade de iluminânciaRay tracingMétodo de elementos finitosLuminaire optimizationLight Emitting Diode (LED)Illuminance uniformity factorRay tracingFinit element methodENGENHARIAS::ENGENHARIA ELETRICATese
