Abstract

DISPOSITIVO DE ILUMINAÇÃO, E, MÉTODO PARA PRODUZIR LUZ A PARTIR DE UMA FONTE DE ILUMINAÇÃO Uma fonte de iluminação (100) inclui pelo menos um diodo emissor de luz (104), p. ex., em arranjo de LEDS que produzem luz de curto comprimento de onda. Um ou mais elementos conversores de comprimento de onda (114A), tais como elementos de fósforo, convertem pelo menos uma parte da luz de curto comprimento de onda dos LED(s) (104) em comprimentos de onda mais longos, tais como Vermelho e Verde. Um elemento dicróico (110), posicionado entre o(s) LED(s) e o(s) elemento(s) conversor(es) de comprimento de onda, transmite a luz dos LED(s) e reflete os comprimentos de onda mais longos do(s) elemento(s) conversor(es) de comprimento de onda. Um painel de seleção de cor (120) seleciona as cores de luz a serem produzidas pelo dispositivo de iluminação (100) e a serem recicladas para outra oportunidade serem convertidas pelo(s) elemento(s) conversor( es) de comprimento de onda (114A) ou a serem refletidas pelo elemento dicróico (110). O painel de seleção de cor (120) pode operar em um ou ambos do domínio especial e do domínio temporal.
