Abstract

Bei einem Lichtmodul wird zur Erzielung einer homogenen Abstrahllichtverteilung und eines blendfreien Fernlichts vorgeschlagen, dass eine erste und eine zweite Primäroptikeinrichtung derart ausgebildet sind, dass die einzelnen LEDs einer ersten und einer zweiten Halbleiterlichtquelle als reelle Zwischenbilder in einer Zwischenbildfläche abbildbar ist, wobei ein der ersten Halbleiterlichtquelle zugeordnetes Zwischenbild mit wenigstens einem der zweiten Halbleiterlichtquelle zugeordneten Zwischenbild überlappt, und dass eine Sekundäroptikeinrichtung derart angeordnet ist, dass die Zwischenbilder Abstrahllichtsegmente der Abstrahllichtverteilung projizierbar sind
