Abstract

trata-se de um dispositivo óptico (201) para modificar um padrão de distribuição de luz de uma fonte de luz (202). a fonte de luz irradia os primeiros feixes de luz a um primeiro espaço de um quarto geométrico e segundos feixes de luz a um segundo espaço de um quarto geométrico, em que o primeiro e o segundo espaços de um quarto são definidos por planos geométricos mutuamente perpendiculares sendo que cada um dos quais constitui uma delimitação entre o primeiro e o segundo espaços de um quarto geométrico. o dispositivo óptico compreende uma seção de lente (207) para modificar um padrão de distribuição de luz dos primeiros feixes de luz e uma superfície de refletor (208) para refletir pelo menos uma parte dos segundos feixes de luz do segundo plano espaço de um quarto geométrico ao primeiro espaço de um quarto geométrico. a superfície de refletor é modelada para lembrar um calço que aponta para o primeiro espaço de um quarto geométrico de modo a fornecer reflexo interno total e para direcionar os segundos feixes de luz refletidos às direções voltadas para os lados.
