Abstract

The invention relates to a low beam headlight with at least one light module. The individual light module exhibits at least one light source and at least one primary lens connected downstream of the light source; and the light source is a luminescent diode. In addition, the low beam headlight has at least one secondary lens, which is connected optically downstream of the primary lens or the primary lenses. Both the primary and the secondary lens exhibit at least two lens segments, which are arranged one over the other. In addition, at least one lens segment of the primary lens and its assigned lens segment of the secondary lens lie outside the optical axis of the light module.The present invention develops a compact low beam headlight, whose light distribution has a clearly defined hot spot. The light intensity of the illumination decreases steadily in the direction of the basic distribution.
