Definitions

  • the present invention relates to a light module comprising means for transmitting a light flux towards optical deflection means for directing said flux towards an output face of the module. It relates more particularly to such a light module further comprising an occluder capable of blocking a portion of the light flux, arranged between the transmitting means and the optical deflection means.
  • These light emitting means are sources of light.
  • the function of the occulting is to block the parasitic rays of the luminous flux emitted by the emission means, so that only a narrow and targeted beam enters the optical deflection means, so that firstly, the rays there are reflected correctly towards the exit face of the module and that, on the other hand, no ray is reflected on adjacent walls delimiting these optical deflection means.
  • the patent application EP-A-2557357 shows a light module with a reflector and a concave arranged on a support wall.
  • the position of the occluder between the light emitting means and the optical deflection means must be determined precisely and that the shape of the occluder must be a function of the shape of the means. optical deflection, so that the occluder can block the first rays judged as parasites and let narrow beam rays directed to the optical deflection means. Particular attention is then paid to the machining of the occluder, as well as to the positioning means of this occluder with respect to the light emitting means.
  • the shape of the optical deflection means may vary from one vehicle to another, it is expected to associate the light modules polarizing means to prevent an incorrect occultor is associated with the optical deflection means, which would have the effect either of not correctly filling the blocking function of the parasitic rays, or of blocking a part of the flow correctly directed towards the optical deflection means and thus of limiting the lighting efficiency of the light module.
  • the invention aims to propose a light module arranged to allow a high accuracy in the shape and positioning of the occultor present in the module.
  • the light module according to the invention is intended to include means for transmitting a luminous flux towards a reflector having means for optically deflecting said flux towards the output of said module, said reflector comprising a support wall which is integral. optical deflection means and which is disposed across said optical deflection means so as to be disposed between said optical deflection means and the transmitting means.
  • the support wall comprises an occultation portion which is arranged facing the emission means and an edge of which is cut so as to form a concealer integrally formed with the support wall, able to pass only part of the emitted rays. by the transmitting means.
  • the embodiment of the occluder directly in the support wall, carrying the optical deflection surface and whose initial function is to stiffen the reflector, is particularly advantageous in that it results from an integration rather than an assembly of insert, which allows the saving of the insert and associated keying means, and allowing a precision in the arrangement of the functional areas relative to each other, thereby avoiding the multiplication of manufacturing and assembly games.
  • the reflector and the support portion are integrally formed in one piece.
  • the reflector, the support portion and the occluder form a single piece.
  • the edge is arranged to block rays that are not oriented towards the optical deflection means.
  • optical deflection means may be reflective surface sections arranged to form part or all of a lighting beam and / or signaling beam by means of the beams they reflect.
  • the illumination beam obtained by means of the rays reflected by the optical deflection means may for example be a road beam, a dipped beam, or a fog beam.
  • a signaling beam it may for example be a stop light, a night position lamp or a diurnal position lamp.
  • the support wall carries means for positioning the transmission means.
  • the support wall carries means for positioning the transmission means.
  • positioning means can be integrally formed with the support wall, and also comprise a pin projecting from the support wall for adjusting the position of the light emission means with respect to the module in two perpendicular directions. parallel to the plane of the support wall.
  • the positioning means further comprise a stop extending projecting from the support wall, for the adjustment in a third direction perpendicular to the first two directions, the height of said stop from the support wall being less than that of said pin.
  • the light module may have, on the support wall, means for fixing a radiator adapted to cover the emission means to ensure thermal cooling.
  • the fixing means may be arranged at at least one transverse end of the support wall while the positioning means are disposed in the vicinity of the occultation portion or between the latter and the fixing means.
  • the light module comprises the light emission means.
  • the light emitting means are supported directly or indirectly by the support wall, in particular via a printed circuit board, or for example via an element carrying the printed circuit board.
  • the invention also relates to a motor vehicle headlamp comprising two light modules as just described above and wherein said two modules are arranged transversely side by side.
  • longitudinal direction L the direction in the direction of movement of the motor vehicle
  • transverse direction T a horizontal direction and perpendicular to this longitudinal direction.
  • the vertical direction V will designate the direction perpendicular to the two previous ones, which also define a horizontal plane.
  • the trihedron L, V, T is placed on the figures for easy reading. But it will be understood that the light module can be arranged according to another orientation without departing from the context of the invention.
  • a motor vehicle headlight has two modules arranged side by side.
  • the following description will detail the structure of a module and it is understood that it can be applied to each of the modules.
  • a light module 1 comprises means 2 for transmitting a light flux and a reflector 4, opposite which are disposed said transmitting means, adapted to concentrate the emitted flux to an output face of the module, not shown here.
  • the module further comprises heat exchange means 6 formed by a radiator attached to the reflector.
  • the light-emitting means comprise here a printed circuit board supporting a light-emitting diode 8.
  • the diode is able to emit, on the basis of an electrical control instruction transmitted by the printed circuits, targeted light rays in the direction of the light-emitting diode. reflector.
  • the light-emitting means may be carried by an interchangeable modular element 10, on one of the faces of which the printed circuit board is made integral, and which is adapted to be fixed in a housing dug in the radiator, so that the carrier face of the diode is turned towards the reflector.
  • the modular element thus facilitates the manipulation of the diode when it is used for its replacement by a new diode.
  • the reflector comprises optical deflection means 12 and a support frame 14, which allows in particular the attachment of the reflector in the light module.
  • the optical deflection means have the shape of a substantially elliptical collector, which has a reflective inner surface.
  • the reflective inner surface of the collector may not be perfectly elliptical and comprise one or more strips 16 of specific or complex profiles in order to optimize the light distribution in the lighting beam.
  • the transverse assembly of these strips forms a generally elliptical general shape, so that the collector has a first focus, on which we will try to arrange the light-emitting diode as precisely as possible, and a second focus on which we have the face of module output.
  • the collector is delimited in a vertical dimension by an upper edge 18 and a lower edge 20, and in a transverse dimension by lateral edges 22.
  • the upper edge of the collector has a substantially elliptical profile while the lower edge of the collector has a profile. accident, which may vary from one module to another, as can be seen in particular on the figure 1 .
  • the support frame 14 comprises at least one rising wall 24 laterally bordering the collector, a substantially horizontal bottom wall 26 which is connected to the lower edge 20 of the collector, and a support wall 28 secured to the upper end of the rising wall. 24 and which extends across the collector, substantially parallel to the bottom wall so as to partially cover the collector.
  • the walls of the support frame are coated with aluminum, especially for aesthetic reasons. These walls do not function to play a role of reflection of light rays but only stiffening of the module. Thus, as will be described in more detail below, it is sought to direct a maximum of the light rays emitted towards the reflecting surface of the optical deflection means which is arranged to allow correct orientation of the light rays at the output of the module, and to block the parasitic rays that could move towards these aluminum walls of the support frame.
  • the support wall 28 is substantially flat. It has a bottom face facing the manifold and an opposite top face. As it is visible on the figure 1 the support wall is arranged across the reflector so that an upper opening 32 is arranged between a rear edge 34 of the transversely extending support wall 28 and the upper edge 18 of the collector, said edge being described as rear edge depending on the general direction of light emission and the direction of this emission to the output of the module, towards the front of the vehicle.
  • the support wall comprises according to the invention an occultation portion 36 which is disposed substantially in the center of the support wall in the transverse dimension.
  • the occultation portion is further distinguished from the rest of the support wall in that it has a vertical stall, by digging the upper face of the support wall. This vertical stall, as it is particularly visible on the figure 2 , does not necessarily extend over the entire longitudinal dimension of the support wall, but originates at the rear edge 34 of the support wall.
  • the support wall carries on its upper face 30 near the occultation portion, positioning means 38 adapted to cooperate with the light-emitting means and it also bears on its upper face, this time with at least one of its transverse ends, fixing means 40 to the radiator.
  • the positioning means 38 take the form of two pairs respectively formed of a pin 42 and a stop 44, these pairs being arranged transversely on either side of the occulting portion.
  • the pin 42 has a cone-shaped portion which protrudes from the support wall for receiving by fitting the light-emitting means pierced with a bore of complementary conical shape. The pin is thus able to maintain the position in two directions, transverse and longitudinal, of the transmission means relative to the support wall and therefore with respect to the occultation portion.
  • the abutment 44 is disposed near the pin and extends projecting to a height less than that of the pin, to allow the transmission means to come to rest vertically on the upper face of the stop while they cooperate with the neighbor pawn. The stop is thus able to allow the positioning of the transmission means in the third direction.
  • the fixing means 40 take the form of drums, which extend substantially perpendicularly projecting from the support wall. These drums can be integral with the support wall or be reported thereon. They are able to cooperate with complementary fixing means 46 which are carried by the radiators and which are visible on the figure 4 .
  • the occulting portion 30 acts as a concealer, formed directly in the support wall, and it is distinguished from the support wall, in addition to its vertical stall in the embodiment shown, essentially by the particular profile of its edge 48 which is corrugated, as opposed to the right rear edge 32 of the support wall extending transversely on either side of the occultation portion.
  • the ripple of the edge profile 48 of the occultation portion is different according to each module and the shape of the optical deflection means. It will be understood, however, that the profile of the edge 48 of the occultation portion advantageously has two lateral sections 50 which extend substantially in the transverse continuity of the rear edge of the support wall and which frame a central section 52 offset longitudinally inwards of the support wall.
  • This particular shape of the profile is obtained by removing material in the central part of the occultation portion, so as to form transversely two lateral zones framing a central zone, of smaller longitudinal dimension.
  • the longitudinal junction 49 between each lateral zone and the central zone may be straight, or substantially inclined relative to the longitudinal direction as is visible on the figure 2 .
  • the function of the lateral zones of the occluder is to block the parasitic rays which tend to move towards the rising walls of the reflector, while the function of the longitudinal clearance formed by the central zone is on the one hand to allow passage, in the zone released, with rays emitted in the direction of the optical deflection surface, and secondly to block by the edge 48 of the occulteur the first parasitic rays directed towards the connection line 54 between the lower edge of the collector and the bottom wall of the reflector support frame.
  • the corrugation of the profile of the edge 48 of the occultation portion is made to correspond to the shape of this connection line 54.
  • the profile of the edge 48 in the central zone is curved, to correspond to the longitudinal shrinkage 56 formed substantially in the center of the connecting line 54, visible on the figure 3 .
  • the reflector is made as visible only on the figure 1 .
  • the support frame 14 and the optical deflection means 12 are integral, and the support frame carries the positioning means and the fastening means formed integrally with the support wall 28, which further comprises the occultation portion 30. It is understood that it is therefore to the machining of this single piece that we can accurately ensure the respect of the ribs between the fastening means and the occluder.
  • the heat exchange means are mounted on the support frame, by the cooperation of the fastening means 40 integral with the frame and complementary means 46 carried by the heat exchange means. These cover the upper opening arranged between the support wall and the upper edge of the collector.
  • the light-emitting means are mounted on the interchangeable modular elements 10, and these are made integral with the radiator, in a position such that the diode 8 is disposed substantially at the first focus of the elliptical collector.
  • This position is ensured by mounting the modular element in the heat exchange means and cooperating the interchangeable modular element, or directly the printed circuit board carried by this modular element, with the positioning means. It can be provided a sliding mounting of the modular element in the heat exchange means to take into account a possible mounting set.
  • the diode In this position, where the diode is disposed substantially at the first focus of the collector, the diode is able to emit a light flux towards the optical deflection means, with the occultation portion which is arranged partly on the path of the emitted rays, between the diode and the optical deflection means.
  • the occultor is thus disposed on the path of the luminous flux, directly at the output of the diode, before any reflection of these rays and the edge of the occultation portion is correctly positioned to sort the parasitic rays of this flow, which are blocked. by the occultation portion, rays correctly directed towards the optical deflection means, which pass through the longitudinal clearance formed by the cutting of the cutting edge.
  • the occultation portion has a vertical stall as can be described above, and it is found in the mounted module that this stall is made in the direction of the distance of the transmitting means.
  • the light module can be attached to the vehicle structure to form all or part of a projector of the vehicle.
  • the module is arranged so that the support wall extends horizontally and so that the side walls of the support frame extend substantially vertically, but it will be understood that the orientation general module could vary without departing from the context of the invention, depending on the final application that is made.
