Motor vehicle headlamp with at least one illuminant (34 fig.5, 34' fig.6, 34" fig.7) for a low-beam light 22, a high-beam light 28 and an ambient illumination 24, which are designed for emitting light upwards or overhead relative to a road plane E, wherein the ambient illumination is emittable combined with low-beam light and/or high-beam light. The lower limit U of the ambient light may have an angle of inclination of 2.5 degrees. The headlamp may comprise an adjustable optical element such as a diaphragm (46, fig.6). A headlamp system comprising the headlamp may further monitor a viewing direction (B, fig.2) of a driver (10, fig.1) and activate the ambient illumination following detection of a viewing angle above 2 degrees from horizontal. Part regions of the light distribution may be faded to reduce glare or dazzle to oncoming or following vehicles. The invention furthermore relates to a motor vehicle headlamp system (3, fig.1), a motor vehicle 2 and to a method for operating a motor vehicle headlamp system. |
