The light device comprises an optical module (), comprising a light source () and an associated optical body () of a transparent material to bind light rays () emitted by the source (). The source () is a multidirectional light source configured to emit the primary light beam () of rays () towards the cover (), and secondary beams () comprising rays () that are approximately transversal with respect to the rays () of the primary beam (). The body () has a front surface () that forms a central front recess () in the body (), a rear surface () that is opposite to the front surface () and is, in the direction from the optical axis (x) of the optical module (), which passes through the source (), inclined towards the cover (), and a lateral surface () connecting the front surface () with the rear surface (). The deepest point of the front recess () is situated approximately at the optical axis (x). The rear surface () and the lateral surface () are configured to prevent rays () from passing through these surfaces ().

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.
