  • This optical module advantageously has a depth, that is to say a bulk in the direction of the optical axis, relatively low and a large luminous flux.
  • this optical module does not make it easy to cut the beam inclined horizontally, for example at 15 °, to produce a light beam filling a function called "code” or "beam dipped".
  • the document EP-A-1491816 proposed to solve this problem by providing an optical module which, while maintaining a shallow depth and a large luminous flux, makes it possible to obtain a large beam reach and, if desired, to cut the beam inclined on the beam. horizontal, especially for a function code.
  • this document proposes to modify the optical module so that the reflector comprises a main portion that reflects incident light rays in the direction of the optical deflection element, while a portion of the light rays is reflected by a portion eccentric secondary of the reflector to participate in the formation of the light beam without passing through the optical deflection element.
  • an interval is reserved between at least a part of the contour of the deflection element, taken in a radial plane with respect to the optical axis, and the front end edge facing radially from the secondary portion of the reflector.
  • the reflector can then be made in one piece, or in several pieces, for example the main portion is arranged longitudinally behind the optical deflection element, and a secondary portion forming a separate element of the main portion is arranged eccentrically radially with respect to the main portion.
  • FIG. 1 an optical module 10 of a motor vehicle comprising a reflector 12, a light source 14 and an optical deflection element 16 by refraction of incident light rays.
  • the light source 14 is capable of emitting light rays substantially in all directions. Subsequently, all the light rays to which reference will be made were originally emitted by the light source 14.
  • the different elements of the optical module 10 can be housed in a housing of a projector (not shown) closed at the front by a smooth glass (not shown).
  • the projector is In addition to the optical module 10 made according to the invention, this module may contain other optical modules each capable of fulfilling one or more associated lighting or signaling functions.
  • the light beam is here a light beam called cross or "code”.
  • This type of light beam is intended to illuminate the road without dazzling the drivers of other vehicles traveling in the opposite direction.
  • the light beam is delimited by a cut line above which the beam does not light.
  • the cut-off line generally has a horizontal profile parallel to the road on the crossing side of the other vehicles so as to illuminate only below the windshield of the other vehicles, and a slope profile, for example at 15 ° with respect to the plan of the road, ascending to the side of the road so as to allow any obstacles or pedestrians walking on the side of the road to be seen at a greater distance than on the crossing side of the other vehicles.
  • the reflector 12 has a concave shape having a front opening which is delimited radially by a front end peripheral edge 18.
  • the front peripheral edge 18 here extends in a radial plane with respect to the optical axis "A" so to be as compact as possible in longitudinal dimensions.
  • the reflector 12 has an optical axis forming the longitudinal optical axis "A" of the optical module 10.
  • the reflector 12 has a focus "F” which is arranged on the longitudinal optical axis "A”.
  • the light source 14 is arranged inside the reflector 12 on the optical axis "A" in the vicinity of the hearth "F". The reflector 12 is thus capable of reflecting the incident light rays emitted by the light source 14 generally towards the front.
  • the light source 14 is for example constituted by the filament of an incandescent lamp, or by the arc of a gas discharge lamp.
  • the orientation of the filament may be axial, transverse or oblique.
  • the optical axis "A" cited above is therefore coincident with the axis of the filament of the lamp when it is chosen to have an axial orientation, as illustrated in FIG. figures 1 and 3 .
  • An optical deflection element 16 is arranged longitudinally in front of the light source 14 so as to be interposed on the optical axis "A".
  • the optical deflection element 16 is here arranged inside the reflector 12, close to the radial plane of the front peripheral edge 18 so as not to increase the longitudinal dimensions of the optical module 10.
  • the optical deflection element 16 is thus interposed on the path of light rays reflected by a first main portion 20 of the reflector 12 or coming directly from the light source 14. Said light rays passing through the optical deflection element 16 are thus deflected by refraction so as to participate in the formation of the light beam.
  • the optical deflection element 16 is constituted by a lens 16 having at least one cylindrical face with a vertical generatrix, capable of ensuring a transverse spreading of the light, without significant influence in the vertical direction.

  • the different faces of the lens 16 are joined by rounded edges which will subsequently be designated by their orientation and by their relative positions.
  • the front exit face 22 of the lens 16 is bounded transversely by vertical edges before 27.
  • the radial contour of the lens is not limited to a rectangular shape, but can also be square, circular, oval, ovoid, ogival, or be of square or rectangular type contour but with rounded edges or cut-sides, or any other outline.
  • the plane face of the lens is turned towards the rear and constitutes the input face while the other curved face constitutes the exit face turned forward.
  • the exit face may optionally have curvatures instead of being flat, especially for reasons of style.
  • the reflector 12 constitutes a substantially convergent mirror that may have locally non-convergent zones, while the lens 16 is partially divergent.
  • the reflector 12 is provided to form the light beam defined by the cut.

  • This is by example of an ellipsoid to converge the reflected light rays on a vertical line at the lens 16 which is located at the second focus before the ellipsoid.
  • This first main portion 20 thus makes it possible to reflect a first portion of the light rays in the direction of the lens 16 so as to partially form the light beam after refractive deflection through the lens 16.
