Illumination system with lens projecting asymmetrical light beam

A shaping device, comprising:

• a light incident surface configured to receive a primary light beam, and defining a main axis substantially normal to a plane of the light incident surface, and
• a plurality of shaping structures, each shaping structure of the plurality of shaping structures comprising at least one first optical surface configured to output emergent beams in a direction at an angle to the main axis,
• wherein the plurality of shaping structures are regularly distributed along a spacing axis substantially perpendicular to the main axis, and extend longitudinally along an extension direction substantially perpendicular to the main axis and to the spacing axis, and
• wherein each shaping structure of the plurality of shaping structures extends in a regular pattern that is substantially sinusoidal and repeated along the extension direction.
