Abstract
A motor vehicle headlight has a light source, a reflector and a mask. The mask has one or more sets of masking elements, such as fins or annular rings, that face each other to form a passage. The passage extends through the mask in a direction away from the light source, thereby allowing heat to escape from the light source without optical leakage.
