Abstract
A lighting device for vehicles contains a flat optical waveguide, which has opposing flat sides and narrow sides connecting them, with numerous microstructure elements on a flat side of the optical waveguide. A number of light sources are positioned on one of the narrow sides of the optical waveguide, and a number of optical films are positioned on the light emission side of the optical waveguide. The optical films have an optical structure for deflecting light on the light emission side. At least one optical film on the side where the light enters has a structure for counteracting capillary effects.
