1. A lighting device comprising: a light source; and a lens positioned in front of the light source, the lens comprising a light entrance surface on a side facing the light source and a light exit surface on a side remote from the light source, and further comprising a plurality of strip-shaped interconnected elongated light guiding elements, of which first ends and spaced apart second ends comprise the light entrance surface and light exit surface, respectively, and light beams emitted by the light source are transmitted by total internal reflection in the elongated light guiding elements in a first direction from the first ends to the spaced apart seconds ends; wherein a length of at least one strip-shaped elongated light guiding element along the first direction is less than a length of the strip-shaped elongated light guiding element along a second direction perpendicular to the first direction; wherein the first ends are spaced apart from each other to define a space between adjacent strip-shaped interconnected elongated light guiding elements, and further wherein the plurality of strip-shaped interconnected elongated light guiding elements are cooperatively arranged to prevent the light beams emitted by the light source from entering the space between the first ends of adjacent strip-shaped interconnected elongated light guiding elements.
