Abstract
A light system includes a light source for emitting divergent light, and only one imaging lens arranged in front of the light source in the divergent light for imaging the divergent light directly received from the light source, where the imaging lens is one-piece fabricated part and comprises a first lens section with a non-structured and convex light entry surface curved in a direction of the light source for the entry of the divergent light of the light source into the imaging lens, a second lens section with a convex light exiting surface curved in a light propagation direction for imaging the light entered, and a mask arranged between the first and second lens sections for modifying the light entered into the first lens section before leaving the light exiting surface.
