Definitions

  • the invention relates to a motor vehicle optical module which is capable of producing a segmented light beam.
  • Optical modules of this type are already known. They are capable of transmitting longitudinally forward a final light beam called “multibeam” or "pixel beam".
  • the final light beam projects forward an image of the matrix of elementary light sources. By selectively switching on or off each of the elementary sources, it is possible to create a final light beam illuminating specific areas of the road in front of the vehicle, while leaving other areas in the dark.
  • Such an optical module is used in particular in front lighting devices to achieve an adaptive lighting function also called "ADB", acronym for the English expression "Adaptive Driving Beam”.
  • ADB adaptive lighting function
  • Such an ADB function is intended to automatically detect a user of the road likely to be dazzled by a beam of light emitted in high beam mode by a projector, and to modify the contour of this lighting beam in such a way that to create a shadow zone at the location of the detected user while continuing to illuminate the long-range road on both sides of the user.
  • the advantages of the ADB function are multiple: comfort of use, better visibility compared to a lighting in dipped beam mode, risk of dazzling greatly reduced, driving safer ...
  • Such a module generally comprises a matrix of primary light sources, generally formed by light-emitting diodes (LEDs), a first primary optical element comprising a plurality of light guides and a projection optics.
  • the light-emitting diodes are arranged on a plane printed circuit board which extends in a plane orthogonal to the projection direction of the final light beam.
  • the light guides of the primary optical element extend generally longitudinally from an entry face of the light to an exit face of the light.
  • the light guides are intended to conform the rays emitted by the light-emitting diodes into a narrower luminous brush having the shape of a pixel, generally rectangular or square.
  • the output faces of the light guides form the matrix of secondary elementary light sources imaged by the projection optics.
  • Such a module requires that the projected image of the secondary elementary light sources has a controlled light distribution and sharpness so that the final light beam formed by the assembly of the images of the secondary elementary light sources has a homogeneous light distribution. This ensures that the driver of the vehicle is not disturbed by light variations due to light intensity dispersions, for example in areas where multiple images of secondary elementary sources are superimposed.
  • Such an optical module is, however, likely to be subjected to optical aberrations such as spherical aberration, coma aberration, distortion aberration, astigmatism, field curvature aberration, etc.
  • the present invention relates more particularly to the resolution of the problems posed by the field curvature aberration also called "Petzval field curvature".
  • the projection optics is supposed to have an object focal surface formed by a plane orthogonal to the optical axis of said optics.
  • this object focal surface actually has a concave spherical curvature.
  • the secondary elementary light sources of the matrix in our case the output faces of the light guides, are arranged in a plane orthogonal to the optical axis of the projection optics, only the secondary elementary light sources located on the focal surface curved object will be projected sharply.
  • the other secondary elementary light sources located in front of or behind the curved object focal surface will be projected in a more or less fuzzy manner according to their longitudinal distance with respect to the object focal surface.
  • the structure of the primary optical element so that the output faces of the light guides are arranged on a curved surface matching the curvature of the real object focal surface of the projection optics.
  • the light-emitting diodes being carried by a flat printed circuit board, the input faces of the light guides are arranged in the same plane.
  • the light guides located at a distance from the optical axis of the projection optics have a length greater than that of the light guides located near the optical axis.
  • the length of the light guides at the ends of the primary optical element is such that the choice of material for producing the primary optical element is limited, for example, to silicone. In particular, it is not possible to produce light guides made of polycarbonate or PMMA.
  • EP 2871406 A1 discloses an optical module for a motor vehicle according to the preamble of claim 1.
  • the optical field correction element is designed so that the image of the curved focal surface of the projection optic by the optical field correction element is an object focal plane in coincidence with the emission plane of the matrix of elementary light sources. Thus, all the light sources are clearly imaged by the projection optics despite its lack of field.
  • the invention also relates to a motor vehicle lighting device of the front projector type which comprises the optical module made according to any one of the preceding claims.
  • the lighting device further comprises a dipped beam module.
  • the vertical orientation "V" is used as a geometrical reference unrelated to the direction of gravity.
  • FIG. 1 an optical module 10 which is intended to equip a lighting or signaling device for a motor vehicle.
  • the optical module 10 is intended to emit a final light beam longitudinally forwards.
  • This is an adaptive light beam that is composed of a plurality of overlapping elementary beams.
  • Such an optical module 10 is particularly capable of fulfilling an adaptive driving beam function, also known by the name "ADB” for "Adaptive Driving Beam”, or it is also capable of performing a directional lighting function, also known as "DBL” for "Dynamic Bending Light”.
  • ADB adaptive driving beam function
  • DBL directional lighting function
  • the lighting device comprises at least the optical module.
  • the optical module 10 mainly comprises means 12 for light emission and a projection optic 14 which is arranged longitudinally forward and away from the transmission means 12.
  • the projection optic 14 has a longitudinal optical axis "A"
  • the lighting device further comprises a second dipped-beam module which is able to emit a single passing beam.
  • the means 12 for light emission here comprise a matrix 16 of primary light sources 18 for light emission. These are electroluminescent diodes 18.
  • the matrix 16 is equipped with two transverse rows of seventeen light-emitting diodes 18.
  • the "A" optical axis passes substantially in the middle of the matrix 16 in the transverse direction.
  • the matrix 16 extends in a plane orthogonal to the longitudinal direction "L". More particularly, the diodes 18 electroluminescent are here borne by the front face of a printed circuit board.
  • electroluminescent diodes 18 are capable of emitting heat during their operation.
  • a heat sink 22 with cooling fins is therefore attached to the back of the printed circuit board 20 to remove heat.
  • the light-emitting diodes 18 emit light rays in a very open cone of light.

  • Each light guide 26 is designed to guide the rays entering through the input face 28 to the exit face 30.
  • each output face 30 forms a secondary elementary light source which will be referred to as "secondary elementary light source 30".
  • the rear portion 24A comprises a matrix comprising at least as many light guides 26 as the matrix 16 comprises light-emitting diodes 18. Each light guide 26 is associated with an electroluminescent diode 18. Thus, the rear portion 24A comprises two rows of seventeen light guides 26.
  • the input faces 28 of the light guides 26 are arranged in a common plane which is parallel to the plane of the printed circuit board.
  • each input face 28 is thus positioned longitudinally vis-à-vis and close to an associated light-emitting diode 18, as illustrated in FIG. figure 4 , so that most of the light rays emitted by each light-emitting diode 18 enter the associated light guide 26.
  • each light guide 26 is capable of having a section adapted to produce a primary elementary light beam emerging from the desired shape for the function of the optical module 10 equipping the lighting or signaling device.
  • the output faces of the light guides 26, forming secondary light sources 30, are arranged in a common emission plane "P" which is parallel to the plane of the printed circuit board 20, as indicated in FIG. figure 4 . In this way, the light guides 26 all have the same length.
  • the exit faces of the light guides 26 thus form a matrix of secondary elementary light sources, here two rows of seventeen secondary sources, each of which is capable of emitting a primary elementary beam in a longitudinal main direction of projection from the common plane "P" emission orthogonal to the longitudinal direction "L".
  • the output faces forming secondary elementary light sources are arranged in close proximity to each other, for example 0.1 mm apart from each other.
  • the primary optical element 24 also comprises a portion 24B before shaping the primary elementary light beams emitted by the elementary light sources 30 secondary. This portion 24B before allows for example to spread the elementary light beams vertically and / or horizontally.
