Abstract
The collimator comprises an output area approximately having the shape of an n-gon with legs and apices, for collimation of light rays emitted by a light source. In viewing the collimator from the side from the optical source in the direction of the lighting axis, the collimator comprises n first parts and n second parts. Each first part is associated with one of the legs of the n-gon and comprises the first sector of the first circular collimator, approximately inscribed in the n-gon so that this leg is tangential to the outline of the circular output area of the first circular collimator. Each second part is associated with one of the apices and is comprised in a second sector of the second circular collimator, approximately circumscribed around the n-gon so that the outline of the output area of this second circular collimator passes through the apex.
