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

In order to obtain a homogeneous emission light distribution and a dazzle-free high-beam, it is proposed in a light module that first and second primary optics are designed such that the individual LEDs of a first and a second semiconductor light source can be imaged as real intermediate images in an intermediate image area, one of the first semiconductor light source associated intermediate image overlaps with at least one of the second semiconductor light source associated intermediate image, and that a secondary optics device is arranged such that the intermediate images Abstrahllichtsegmente the Abstrahllichtverteilung be projected
