Abstract
A device is provided for compensating for thermal expansion in a headlamp, such as for a vehicle. A compensator is configured to expand or contract in an expansion direction (A), depending on the temperature. A tappet is functionally connected to the compensator that moves in a compensation direction (K) when the compensator expands or contracts along the expansion direction (A). A lever rotationally and/or pivotally connects the compensator to the tappet to obtain the functional connection.

A device for compensating for thermal expansion in a headlamp, the device comprising:
- a compensator configured to expand or contract in an expansion direction (A), depending on the temperature;
- a tappet functionally connected to the compensator that moves in a compensation direction (K) when the compensator expands or contracts along the expansion direction (A);
- a lever that rotationally and/or pivotally connects the compensator to the tappet to obtain the functional connection;
- and
- wherein a hole is positioned in the lever into which a pin is inserted, about which the lever rotates and/or pivots.
A device for compensating for thermal expansion in a headlamp, the device comprising:
- a compensator configured to expand or contract in an expansion direction (A), depending on the temperature;
- a tappet functionally connected to the compensator that moves in a compensation direction (K) when the compensator expands or contracts along the expansion direction (A);
- a lever that rotationally and/or pivotally connects the compensator to the tappet to obtain the functional connection;
- and
- further comprising a retainer with which the device is adjustably retained on or in the headlamp, wherein the retainer is aligned with the tappet, wherein the retainer and tappet are spaced apart, and the distance between the retainer and the tappet changes with the temperature.
