Abstract
A lighting device with a light source followed by an optical apparatus in an emission direction, and a primary optics element with a light inlet and a light outlet being arranged between the light source and the optical apparatus. The primary optics element is designed such that desired characteristics of the light beam are formed within the primary optics element by deliberate reflections on specially shaped reflective surfaces of the primary optics element.
