  • the output optical system 16 is interposed in the path of the parallel beam 14 so as to deflect the light rays to form the regulatory lighting or signaling beam 18.
  • the output optical system is formed by an output diopter 16 which deflects the light rays by refraction.
  • Such a device has the advantage of being very compact compared to a device provided with a reflector. Indeed, the radial size of the device is here limited by the cross section of the beam of parallel rays 14.
  • regulatory beams having, in at least one axial plane, an angular aperture greater than a limit angular aperture.
  • the angular aperture is defined as being the angle formed between the main axis of the regulatory beam and the envelope of the regulatory beam, in a given axial plane.
  • the light beams having an angular aperture greater than a limit angle, such as that of a reversing light, can not physically be made by the refraction of a beam of parallel rays alone.
  • the exit diopter 16 has concave or convex patterns.
  • the angle of refractive deviation depends on the angle formed between the incident ray and the normal to the local surface of the diopter.
  • the incident parallel light rays are no longer refracted by the output diopter 16, but they undergo a total reflection.
  • the light rays thus reflected "flee" radially in a ring 20 around the regulation light beam, leaving a dark area around the lighting beam.

More particularly, the intermediate optical system deflects the light rays in at least a first plane of aperture, and the output diopter accentuates the deviation of light rays in said aperture plane. This makes it possible to obtain beam opening angles in the beam opening plane which are much higher and notably an angular aperture greater than the limit angular aperture.
