Abstract
Et flerlampearrangement for optiske systemer innbefattende to lamper eller flere (10, 15), og en kollektiv lysleder (58), hvor hver lampe er anbrakt for å overføre lys (20) til respektive lysledere (36, 46) som begge på optisk vis er forbundet med den kollektive lyslederen (58). I en legemegj øring er en av lampene på optisk vis forbundet med den kollektive lyslederen ved hjelp av et speil (38)- og-prisme (40)-arrangement og en mellomlysleder (30) og et mellomliggende speil (32- og-prisme (34)-arrangement. Oppfinnelsen innbefatter også en utvidet faremodulator (62) med et antall fargefelt, hvor antallet av identiske fargefelt er lik lampeantallet. Det opprinneriske flerlampesystemet vil fermbringe et fluksnivå som er lik eller bedre det hos kjente systemer, men med færre lamper, og tilveiebringer således reduserte materialkostnader, redusert effektforbruk og redusert produkttemperatur.
