Abstract
The light device comprises an optical module (17), comprising a light source (5) and an associated optical body (8) of a transparent material to bind light rays (10) emitted by the source (5). The source (5) is a multidirectional light source configured to emit the primary light beam (6) of rays (10) towards the cover (1), and secondary beams (7) comprising rays (10) that are approximately transversal with respect to the rays (10) of the primary beam (6). The body (8) has a front surface (12) that forms a central front recess (18) in the body (8), a rear surface (14) that is opposite to the front surface (12) and is, in the direction from the optical axis (x) of the optical module (17), which passes through the source (5), inclined towards the cover (1), and a lateral surface (13) connecting the front surface (12) with the rear surface (14). The deepest point of the front recess (18) is situated approximately at the optical axis (x). The rear surface (14) and the lateral surface (13) are configured to prevent rays (10) from passing through these surfaces (14, 13).
