Optical system for motor vehicle for low visibility lighting, especially in fog, heavy rain or snowfall

摘要

The optical system comprises an optical part with an active part (1) made of optically transparent material, a collimating element (2) and a light unit (3) for emitting light beams (10) into the collimating element (2) for collimating the light beams (10) and their routing to the active part (1). The active part (1) has on its front side an exit surface (12) for outputting the light rays (10) out of the active part (1) towards the display surface (ZY) spaced in front of the active part (1) and comprises optical elements ( 13), the output faces (15) of which are part of the exit surface (12) for producing light patterns (A) on the display surface (ZY). The optical elements (13) are formed by convergent lenses (13a) and / or divergent lenses (13b), the optical elements (13) being arranged one after the other in rows located one beside the other.
