Abstract

Et prismelys-lederarmatur (84) har opake (102) og lysemitterende (88) flatepartier som tilsammen danner en valgt tverrsnittsutforming. Det opake flateparti har en lysreflekterende karakteristikk. Det lysemitterende flateparti er et prismelys-leder- materiale (100) som innenfor armaturet avgrenser lysstråler som treffer materialet i vinkler som faller innenfor materialets aksept-vinkelområde. Inne i armaturet omdirigerer et lysspredende område (92, 94) med en forhåndsbestemt form og plassering lys til vinkler som faller utenfor materialets aksept- vinkelområde. Armaturets tverrsnittsutforming, det opake flatepartis lysreflekterende karakteristikk, og form og plassering til det lysspredende område er valgt slik at (i) lys omdirigert av det lysspredende område som ikke går direkte fra det spredende område til det lysemitterende flateparti og unnslip- per gjennom dette parti, hovedsakelig effektivt, ved hjelp av prismematerialet, reflekteres direkte tilbake på det spredende område; og (ii) alle veier langs hvilke lys kan gå direkte fra det spredende område til det lysemitterende flateparti definerer en rom- vinkel mindre enn 2n.
