Abstract
Illumination device (1) for a motor vehicle headlight, comprising an illuminant, an optical element (2) for forming light distribution, wherein the optical element (2) has a focal point, a holding device (3), which holds the position of the optical element (2) in relation to the illuminant, wherein the holding device (3) has a compensating element (4), which connects the optical element (2) to the holding device (3), wherein the compensating element (4) has a first end section (4a) and a second end section (4b), wherein the first end section (4a) is connected to the optical element (2) and the second end section (4b) is connected to the holding device (3), wherein the compensating element (4) is designed in such a way that the compensating element (4) has a temperature-dependent longitudinal extension in one direction (X), wherein the compensating element (4) is connected to the optical element (2) in such a way as to pivot and/or move the optical element (2) as a function of a temperature relative to a light image plane in such a way that the focal point of the optical element (2) lies within the light image plane.
