Motor vehicle headlight with a lens holder which compensates for fluctuations in temperature

The headlight (10) has a primary lens (20) and a secondary lens (22), which are attached by a holder (32) of the primary lens and a holder (34) of the secondary lens. The holders are equipped in such a manner that a value of distances (d1, d2) between light exit surfaces (16.2, 18.2, 20.2) and light...

Zusammenfassung:	The headlight (10) has a primary lens (20) and a secondary lens (22), which are attached by a holder (32) of the primary lens and a holder (34) of the secondary lens. The holders are equipped in such a manner that a value of distances (d1, d2) between light exit surfaces (16.2, 18.2, 20.2) and light entry surfaces (20.1, 22.1) is obtained. The light entry surfaces receive light from the light exit surfaces. The value is adjusted to a reference value based on temperature change by thermally conditional length change of the holders. The temperature change is released from the light exit surface.
