Abstract
An illumination device for vehicles with a first light module for producing a first light distribution and with a second light module for producing a second light distribution. The second light module has numerous semiconductor-based light sources arranged as a matrix, a primary optics unit with primary optical elements assigned to each of the light sources and a secondary optics unit. An intermediary optics unit is arranged between the primary optics unit and the secondary optics unit of the second light module; the intermediary optics unit is designed so that a light-intensity gradient of the second light distribution gradually diminishes in a vertical and/or horizontal direction in a lower subarea, in which the first light distribution of the first light module connects or overlaps with an upper subarea.
