Abstract
''ESTRUTURA óTICA DE SEPARAçãO''. Uma estrutura de separação ótica 10 que compreende uma porção de corpo transparente unitário que se estende entre uma primeira extremidade larga 23 e uma segunda extremidade distal 25 define uma estrutura em forma de cunha. A porção de corpo 14 inclui uma porção frontal que define uma superfície frontal de iluminação geralmente planar 22, uma porção traseira 12 que tem uma pluralidade de facetas chanfradas redirecionadoras 20, espaçadas, separadas por áreas intermediárias 18, e uma pluralidade de elementos óticos 60 colocados dentro das áreas intermediárias 18. Uma primeira fonte luminosa 26 é acoplada na extremidade larga 23 para transmitir luz longitudinalmente através da porção de corpo, no sentido das facetas redirecionadoras 20. As facetas redirecionadoras 20 tendo superfícies refletoras 30 transversais à superfície frontal planar de iluminação 22, para refletir e difundir a luz 28 no sentido da superfície frontal, em uma distribuição de luz de intensidade relativamente baixa. Uma segunda fonte luminosa 34 é acoplada adjacente à porção traseira, atrás das áreas intermediárias. Os elementos óticos 60 transmitem a luz 38 diretamente através das áreas intermediárias 18 no sentido da superfície frontal 14 em uma distribuição de luz de intensidade relativamente alta. Os elementos óticos 60 podem também incluir facetas cóncavas, convexas e/ou facetas para conformar a luz direta no sentido da superfície frontal de iluminação 22.
