An illumination apparatus for vehicles having a light source, a support plate for receiving the light source, and an optical unit arranged in front of the light source in the main emission direction to deflect light emitted by the light source onto a roadway in front of the vehicle in accordance with a predetermined light distribution. The light source has a light-emitting surface and a light source frame surrounding the same. The light source is surrounded by a shielding frame with a wall that is raised in the main emission direction and encloses an intermediate space between the light source and the optical unit.
