Abstract

Die Erfindung betrifft einen Abblendlichtscheinwerfer (10) mit mindestens einem Lichtmodul (20), wobei das einzelne Lichtmodul mindestens eine Lichtquelle (30) und mindestens eine der Lichtquelle nachgeschaltete Primärlinse (50) aufweist und wobei die Lichtquelle eine Lumineszenzdiode ist. Dazu hat der Abblendlichtscheinwerfer mindestens eine Sekundärlinse (90), die der Primärlinse (50) oder den Primärlinsen optisch nachgeschaltet ist. Sowohl die Primär- als auch die Sekundärlinse weist mindestens zwei übereinander angeordnete Linsensegmente auf.
Mit der vorliegenden Erfindung wird ein kompakter Abblendlichtscheinwerfer entwickelt, dessen Lichtverteilung eine gleichmäßige Grundverteilung und einen deutlich ausgeprägten Cut-off aufweist.

The invention relates to a dipped-beam headlamp (10) with at least one light module (20), wherein the individual light module has at least one light source (30) and at least one primary lens (50) connected downstream of the light source and wherein the light source is a light-emitting diode. For this purpose, the low beam headlamp has at least one secondary lens (90) which is optically connected downstream of the primary lens (50) or the primary lenses. Both the primary and secondary lenses have at least two superimposed lens segments.
With the present invention, a compact low-beam headlamp is developed whose light distribution has a uniform basic distribution and a pronounced cut-off.
