Abstract

A lighting device for vehicles having a housing, in which a light source unit for emitting a light beam and an optical unit associated with the light source unit for generating a predetermined light distribution are disposed, with a cover plate closing an opening of the housing and with a cooling element for dissipating heat from the light source unit. The cooling element is associated with a heat-dissipating optical element of the optical unit. A dividing wall separating the housing into a first chamber and into at least a second chamber is provided, wherein in the first chamber, the first cooling element associated with the light source unit, and in the second chamber, the second cooling element associated with the heat-dissipating optical element of the optical unit are arranged.
