Abstract


Este trabalho discute como realizar projetos de iluminação artificial com luminárias de LEDs com o objetivo de aumentar a qualidade nutricional de verduras e frutas, especialmente em relação ao teor de antioxidantes e vitaminas. Essas substâncias podem ajudar na prevenção de doenças, constituindo uma alternativa interessante na promoção de saúde. Sabe-se que os efeitos da luz sobre as plantas dependem de muitos fatores, a saber, da duração, da intensidade e do comprimento de onda. Cada planta tem requisitos próprios, necessitando de estudos específicos. Este trabalho propõe uma metodologia que dê suporte para a execução de projetos com luminárias de LEDs em horticultura, propiciando maior precisão no PPFD (Photosynthetic Photon Flux Density). São apresentados os resultados da aplicação desta metodologia para uma luminária de LEDs, mostrando a distribuição da luz e os efeitos do distanciamento da luminária em relação ao plano de medição.
