Abstract

The device (21) has optical modules (22, 22 ', 23, 23') mounted on different supports (27, 28). Each module has a first assembly or a second assembly or a reflector whose complex surface collects light from a light source (51) and produces, towards front, a corresponding light beam with a cut. Each assembly has a collector (53) to collect the light, and a bending unit (54) with a cut edge to authorize only the passage of a part of the light from the collector for producing the corresponding light beam and its cut. The second assembly has a lens to focus the light from the collector. The light source is a single chip LED.
