ABSTRACT:
The invention relates to an illumination device, particularly for automobiles, with a light source and a light conductor that emits the light from the light source conducted within it via a light decoupling surface, whereby light decoupling elements are positioned on the side opposite the light decoupling surface that divert light toward the light decoupling surface, whereby the light decoupling elements possess at least two diverting surfaces, and the first diverting surface is positioned closer to the light source than the second diverting surface of a light decoupling element, each of which subtends an angle with the light decoupling surface whereby the angles of the diverting surfaces are so selected that at least a portion of the light striking the second diverting surface is transmittable through it under refraction, and may be again coupled into the light conductor by means of the first diverting surface of the subsequent decoupling element, whereby this light is at least partially conducted from the first onto the second diverting surface of an decoupling element, and may be decoupled toward the decoupling surface by means of the second diverting surface.
