Lighting means having a primary optics element and an optical apparatus

A lighting means comprising:

• a light source;
• and
• an optical apparatus which is arranged downstream from the light source in an emission direction;
• and
• a primary optics element comprising a light inlet and a light outlet disposed between the light source and the optical apparatus, the light outlet or an imaginary surface, being located in a beam path of the light emitted from the light source, is projected by the optical apparatus;
• wherein the primary optics element has the form of a non-imaging concentrator which, compared with a normal use of a concentrator, allows radiation to pass through in an opposite direction;
• and
• wherein the light outlet of the primary optics element, seen in a plan view, has a long shape with a first longitudinal face and a second longitudinal face opposite the first longitudinal face, the first longitudinal face being closer to the light inlet than the second longitudinal face.
