Abstract

A supplementary light module for a headlamp of a vehicle, and in particular a cornering light module, a turning light module, or a fog light module. Such module can be accommodated in a housing of the headlamp, comprising a lamp and a reflector. The light generated by the lamp can be emitted in a propagation direction. A base body is provided, on which at least the lamp and the reflector are accommodated, and wherein the base body is securely accommodated in the headlamp housing by means of a pivot axle and by means of an adjustment unit for adjusting the supplementary light module about the pivot axle.

First claim

The invention claimed is:

1. A supplementary light module for a headlamp of a vehicle, said supplementary light module being at least one of a cornering light module, a turning light module, and a fog light module, said supplementary light module comprising:
a lamp;
a reflector by means of which light generated by the lamp can be emitted in a propagation direction;
a base body on which at least the lamp and the reflector are accommodated;
a pivot axle having a longitudinal axis aligned in a first direction, said pivot axle fixedly attaching the base body in the headlamp housing; and
an adjustment unit aligned in a second direction different than the first direction for attaching the base body in the headlamp housing and for adjusting the supplementary light module about the fixed longitudinal axis of the pivot axle in an adjustment axis; and
wherein the supplementary light module is accommodated in a housing of the headlamp.

2. The supplementary light module according to claim 1 , wherein the base body is designed as an integral unit, and wherein the pivot axle runs at least in part through the base body.

3. The supplementary light module according to claim 1 wherein the base body is made of aluminum, and serves to cool at least the lamp.

4. The supplementary light module according to claim 1 wherein the propagation direction of the light runs substantially in a horizontal plane, and wherein the adjustment unit is designed to tilt the base body about the pivot axis.

5. The supplementary light module according to claim 1 wherein the adjustment unit comprises an adjustment screw, which extends vertically through the headlamp housing, and can be manipulated from the exterior of the housing.

6. The supplementary light module according to claim 1 wherein the adjustment unit comprises an elastic element, which is disposed between the base body and the housing.

7. The supplementary light module according to claim 1 , wherein a temperature measuring device is provided on the base body.

8. The supplementary light module according to claim 1 wherein an adjustment plane is formed through the pivot axle and through a connecting point formed between the base body and the adjustment unit, wherein the propagation direction of the light runs substantially parallel to and over the adjustment plane.

9. The supplementary light module according to claim 8 , wherein the base body has a center of gravity, which is covered by the adjustment plane, and lies in the adjustment plane.

10. A headlamp having a supplementary light module according to claim 1 .
