Abstract

Um den Wirkungsgrad bzw. die Lichtausbeute bei einer streckenförmigen Strahlenquelle (2) zu verbessern, wird ein Reflektor vorgeschlagen, der die Strahlenquelle umfänglich mit mehreren Fresnelzylinderlinsen (3) umgibt. Durch Prismenstücke (5) bzw. Lichtleitstüke (6), die sich an die seitlichen bzw. unteren Fresnelzylinderlinsen (3) anschließen, wird das von der Strahlenquelle (2) erzeugte Licht nahezu vollständig reflektiert bzw. umgeleitet und tritt als parallel sich fortpflanzende Lichtstrahlen in einer Austrittsrichtung aus dem Reflektor aus.
