Abstract-This article presents the optical design of a six-spectral LED-based solar simulator. The study focuses on the measurement methods of spectral match, the non-uniformity and the temporal instability on the test plane. The proposed six-spectral LED solar simulator has an illuminated area of 900 cm 2 and can characterize medium size photovoltaic devices under variable irradiance. The spectral range covered is between 400 nm and 1100 nm which offer the capability of characterizing silicon PV technologies. The evaluation method is in accordance with IEC 60904-9. The Solar Power meter was used to measure the irradiance and a Compact Array Spectrometer and Fiber optic spectrometer were applied for the spectral match test. The irradiance is controlled via LabVIEW which can adjust the power to drive all LEDs in the constant current mode. The irradiance of 1000 W/m 2 was applied during testing. The results found that the spectral match classification is of class B. The non-uniformity of irradiance is of A-class across the illuminated area. The temporal instability of irradiance is capable of reaching class A. This idea is perfectly appropriate for the application of the testing of I-V characteristic of the silicon solar cell. For future work, the author has to improve the spectral match to reach an A Class.

Este trabalho apresenta a concepção e o desenvolvimento de um sistema de iluminação baseado em diodos emissores de luz (LEDs) capaz de reproduzir espectros da luz com precisão para aplicações que exigem um espectro da luz específico. A metodologia proposta utiliza Programação Matemática, através de um modelo de Programação Linear Inteira Mista, para obter a combinação ótima de modelos de LEDs que resultam no espectro mais próximo possível da referência. Os LEDs de cada modelo selecionado pelo procedimento de otimização são acionados por um sistema eletrônico composto por conversores Buck com controle de corrente por histerese e controle de intensidade luminosa por Modulação por Largura de Pulso. O controle independente de cada modelo de LED permite a possibilidade de variar a intensidade e a distribuição espectral da luz, agregando flexibilidade ao sistema de iluminação. Como aplicação prática, um sistema é desenvolvido para reproduzir o espectro da luz solar para diferentes horários do dia. Os testes para validação da metodologia proposta demonstraram que é possível reproduzir determinados espectros com fidelidade, com um erro relativo médio de 12% entre o espectro projetado e o espectro referência, considerando os modelos de LED disponíveis.
