Abstract
The invention relates to a lighting device with a multiple light function, which comprises a primary light source and secondary light source (2a, 2b) associated with optical elements which are adapted to guide light to the output of the device. The primary light source (2a) is associated with collimating elements (4) and the secondary light source (2b) is associated with light guiding elements (3), whereby the collimating elements (4) and the light guiding elements (3) are arranged in a common light guiding body (A), the output of the light beams is situated behind the level (6) of the exit ends of the collimating elements (4) and on the output side of light guiding body (A) a light scattering filter (7) is arranged.
