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.
Claims30
A primary optics element in 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, the primary optics element comprising a light inlet and a light outlet which, seen in a plan view, has a long shape with a first longitudinal face opposite to a second longitudinal face, the primary optics element having a cross section in the form of a polygon which has at least one rounded corner, on the light outlet side.
A lighting means comprising:
- a light source;
- and
- an optical apparatus disposed downstream from the light source in an emission direction and projecting a curved imaginary surface, the optical apparatus comprising a projection lens with a focus area that lies on the imaginary surface;
- and
- a primary optics element with a light inlet and a light outlet disposed between the light source and the optical apparatus.
