Abstract
En ytre prismelysleder (48) omgir et deksel (52) som igjen omgir en lyskilde. Lederen (48) er dannet av prismelyslederveggmateriale med ensartet form i tverrsnitt perpendikulært til en første oktatur symmetriretning (44), med sin optiske senterlinje (50) parallell til retning (44). Overflater på veggmaterialet er i hovedsak i oktatur relativt til retning (44). En overflatenormal vektor (46) på ethvert punkt på enhver indre overflate av materialet er enten i hovedsak parallell eller i hovedsak perpendikulær til en første tenkt linje som Strekker seg fra punktet gjennom og perpendikulært til den optiske senterlinje (50). Deksel (52) har sylindrisk symmetri rundt den optiske senterlinje (50) for å fange opp en vesentlig andel av lys avgitt av kilden. Deksel (52) er dannet av prismelyslederveggmateriale, med overflater på veggmaterialet i hovedsak i oktatur på ethvert punkt (54) på deksel (52) relativt til en annen, romlig variabel oktatur symmetriretning (56), som ved punkt (54) er perpendikulær til første oktature symmetriretning (44); og perpendikulær til en andre tenkt linje (58) som strekker seg fra punkt (54) gjennom og perpendikulært til optisk senterlinje (50). En overflatenormal vektor ved ethvert punkt på enhver ytre overflate på deksel (52) er enten i hovedsak parallell eller i hovedsak perpendikulær til første oktature symmetriretning (44). Deksel (52) er begrenset til et område tilstrekkelig nærme den optiske senterlinje (50) til i hovedsak å forhindre forplantning av lysstråler insident på en indre overflate av dekselet (52) til og gjennom lyslederveggmaterialet.
