Abstract
A light module comprises a light-exit section, a base light source that exhibits at least one LED with a light-emitting surface limited by an edge, a reflector open to the light-exit section for collimating light on a meridional plane, and a cylinder lens for collimating the light on a sagittal plane running perpendicular to the meridional plane. The reflector on the sagittal plane is free of curvature and is curved on the meridional plane such that a focal line is defined. The base light source is arranged such that the edge runs on the focal line, and the light-emitting surface proceeds from the focal line extending in a direction of the light-exit section so that the light radiated from the light module exhibits a basic light distribution with a “light/dark” boundary.
Claims15
A light module (10, 50, 60, 70, 80) for a motor-vehicle headlight, the light module (10, 50, 60, 70, 80) comprising:
- a light-exit section (17) through which light can be radiated in a main direction of emission (15);
- a base light source (12) that exhibits at least one LED (76) with a light-emitting surface (77) limited by an edge (13, 78);
- a reflector (14) open to the light-exit section (17) for collimating the light on a meridional plane;
- and
- a cylinder lens (18) for collimating the light on a sagittal plane running substantially perpendicular to the meridional plane,
- wherein the reflector (14) on the sagittal plane is free of curvature and curved on the meridional plane such that a focal line (20, 75) is defined, the base light source (12) is arranged such that the edge (13, 78) runs on the focal line (20, 75), and the light-emitting surface (77) proceeds from the focal line (20, 75) extending in a direction of the light-exit section (17) so that the light (26) radiated from the light module exhibits a basic light distribution with a “light/dark” boundary (HDG).
