Abstract

"FIBRA DE LUZ, E, PROCESSO PARA PRODUZIR A MESMA". Objetivo: fornecer uma fibra de luz do tipo de extração de luz lateral capaz de extrair a luz tendo alta claridade em um ângulo de visão. Meios para resolver: uma fibra de luz que compreende: um núcleo (1) na parte central e um revestimento disposto em volta do dito núcleo, caracterizado em que o dito revestimento compreende: (i) uma camada difusora de luz (3) que compreende uma parte difusora de luz feita de um material difusor de luz que contém, como um aglutinante, um polímero tendo um índice de refração menor do que o do dito núcleo, que é fomecido em contato rente com o dito núcleo em uma espessura de parede de 1 a 300 <109>m em uma direção circunferencial, e (ii) uma camada protetora (4) feita de um material de resina de transmissão de luz, que é formada para integrar com a dita camada difusora de luz e revestir a dita camada difusora de luz.
