Definitions

  • the present invention relates to the field of lighting and/or light signaling in the automotive field, and more particularly to light modules configured to perform such a lighting and/or signaling function.
  • the field of lighting and/or light signaling of motor vehicles is subject to regulations which require that each motor vehicle be equipped with lights, fulfilling specific safety functions, and in particular high beams and dipped headlights.
  • Low beam headlights allow a motor vehicle to be seen by other users and its driver to properly see the roadway up to 30 meters away, without dazzling the users present on the road scene.
  • the high beams emit more intense light beams so that the driver of the motor vehicle can see the roadway properly, at least 100 meters away at night.
  • the low beam and main beam headlights are respectively implemented by a light module, each light module being able to comprise an essentially point light source, for example of the light emitting diode type, and a reflector, which comprises a reflective surface of revolution with an elliptical profile, the light module may also include a support which serves as a reference for fixing the source and the reflector.
  • the light source is then located at a first focus of the reflective surface, being oriented so as to illuminate essentially in the direction of said reflective surface.
  • the light rays are reflected in a convergent manner towards a second focus of the reflective surface of the collector, merged with a focus of an optical element of the light module, such as a lens, configured to project a light beam reflected by the reflector towards the pavement.
  • the light module includes a protective cover to prevent any leakage of light rays outside the light module except through the optical element.
  • the optical element is generally of elongated and substantially rectangular shape, thus having two sides of larger dimension than the other two sides.
  • the larger sides are oriented mainly parallel to the roadway to advantageously project the light beam of the light module over the width of the roadway while avoiding dazzling the drivers of other vehicles.
  • the optical element is integral with the support and/or the protective cover, in particular to freeze the position of the latter and thus so that the focus of the optical element remains coincident with the second focus of the reflector, so as to ensure that the beam emitted by the optical element is correctly projected onto the roadway.
  • the support and/or the protective cover of the light module is integral with the optical element at the larger sides of the optical element.
  • This attachment of the optical element to the support and/or to the protective cover at the level of its larger sides induces the formation of zones of luminous inactivity on the optical element.
  • the zones for fixing the optical element with the support and/or the protective cover consist of opaque zones preventing the light rays emitted by the light source from passing towards the road.
  • These fixing zones of the optical element thus reduce the active zone through which the light rays pass through the optical element, reducing the optical efficiency of the light module.
  • the presence of these fixing zones implies an increase in the size of the light module on each larger side, which tends to penalize the visual rendering that we wish to give with the use of an element elongated optics, or thin lens.
  • the document US 2017/291532 A1 shows the holding in position of an optical element on a support in the longitudinal direction by the deformable tabs of a mask.
  • the present invention proposes an alternative to existing solutions for fixing an optical element to a support and/or protective cover of a light module which allows said light module to present an active optical zone, i.e. that is to say a zone through which the light rays emitted by the light module pass through the optical element, of maximum dimensions.
  • the first aspect of the present invention is a vehicle light module according to claim 1.
  • the light module which is the subject of the invention comprises on the one hand the transparent optical surface, which can be considered as a projection lens of the module, configured to conform the light rays emitted by the light source into a beam regulatory light to be projected onto the roadway, and on the other hand fixing means arranged laterally which allow the positioning of the transparent optical surface facing the path of the rays emitted by the light source.
  • the transparent optical surface that is to say the projection lens of the module, has an elongated shape, presenting a main direction here transverse. From the front, the transparent optical surface thus has a substantially rectangular shape with the largest sides arranged transversely.
  • the lateral fixing means are arranged on either side of the transparent optical surface, at the transverse ends of this transparent optical surface, making it possible to fix the transparent optical surface laterally to a structuring element of the light module.
  • the transverse ends of the transparent optical surface participate in securing the latter to a structuring element, and in particular a support for the light source and the reflector. It is understood that the fixing means are not present on the other edges of the transparent optical surface, leaving the transparent optical surface clear in particular on its long transverse sides, which maximizes the operational optical surface, that is to say the optical surface not masked by the fixing means.
  • the fixing means is a fixing tab extending substantially perpendicular to the transparent optical surface along a longitudinal axis.
  • the transparent optical surface is advantageously positioned perpendicular to the optical axis of the light module, that is to say the main direction of movement of the emitted rays, so as to be able to conform these rays into a beam projected onto the roadway, and the fixing lugs extend in this way substantially parallel to the optical axis between the light source(s) and the transparent optical surface or where appropriate between the reflector and the surface transparent optics.
  • the fixing lugs of the transparent optical surface can be arranged laterally without hindering the propagation of the light rays in the direction of this transparent optical surface.
  • Each fixing tab has a substantially planar shape, that is to say a shape of which one dimension, here the thickness along the transverse dimension, is less than the other two dimensions, and in particular the longitudinal dimension mentioned above.
  • the low thickness along the transverse dimension makes it possible to minimize the opaque zone that can be visible through transparency to an external observer facing the transparent optical surface.
  • the means for fixing the optical element and the transparent optical surface of the optical element form a single piece assembly.
  • the assembly is said to be in one piece in that the elements which compose it, namely the transparent optical surface and the fixing means, are inseparable from each other, that is to say that the separation of these components cannot be done without leading to the degradation or destruction of at least one of the components.
  • the optical element comprising transparent optical surface and fixing lugs is made in one piece, with a single block formed of a single material.
  • Each component of the optical element is thus made up of the same base material, where appropriate locally charged, so that the fixing lugs are made of a transparent or translucent material, without their having any optical function.
  • the invention also relates to a light module comprising an optical element conforming to what has just been described, the light module comprising at least one light source whose emitted rays pass through the transparent optical surface of the optical element emerging in the form of a light beam.
  • the light module comprises at least one support for the at least one light source and the optical element, the support having a housing for each means of fixing the optical element.
  • Each housing formed specifically in the support to receive a fixing tab of the optical element participates in the positioning, maintaining in position and fixing of the optical element relative to the support.
  • the fixing means being, as mentioned above, a fixing tab extending substantially along the longitudinal axis
  • the fixing tab comprises at least one positioning stud for the optical element capable of cooperating with a groove made in a wall of the housing to ensure the position of the optical element relative to the support along the longitudinal axis, and/or at least one positioning pin of the optical element capable of being supported on a wall of the housing to form a vertical positioning stop of the optical element relative to the support along a vertical axis perpendicular to the longitudinal axis and the transverse axis.
  • Each positioning pad and each positioning pin is configured to cooperate with a positioning member formed on or by a wall of the support to enable the optical element to be positioned relative to this support.
  • each positioning means carried by the fixing tab makes it possible to place in position, and where appropriate to maintain in position, the optical element along a particular axis.
  • the positioning pad and the complementary positioning member are configured to ensure that the optical element, and therefore the transparent optical surface, is maintained in position relative to the longitudinal axis.
  • the positioning pin and its complementary positioning member that is to say a wall against which the pin abuts, are configured to ensure a stop in the vertical position of the fixing bracket, maintaining it in position according to this direction is also done by clamping the fixing tab between the support and a reflector of the light module or between the support and a protective cover of the light module such as they will be presented below.
  • the positioning pad of the optical element and the positioning groove of the housing are configured, in particular by their shapes and their dimensions, so as to ensure the positioning of the optical element relative to the support along the longitudinal axis, the positioning stud being able to be partially housed in the groove, the faces of the stud being in contact with or in the close vicinity of the walls delimiting the housing longitudinally.
  • the at least one positioning pad of the optical element and the at least one positioning pin are formed on the same face of the fixing tab.
  • each fixing tab has an internal face oriented opposite the other fixing tab, that is to say towards the inside of the light module, an opposite external face, c that is to say oriented towards the outside of the light module, an upper face and a lower face connecting the internal face and the external face, the lower face being arranged facing a bottom wall of the corresponding housing, the module being characterized in that the at least one positioning stud of the optical element and the at least one positioning pin are formed on the lower face of the fixing tab, the groove being able to cooperate with the bottom wall housing.
  • the fixing bracket thus advantageously comprises four faces, the fixing bracket advantageously extending in the form of a rectangular parallelepiped.
  • the lower face of this rectangular parallelepiped is substantially perpendicular to the internal face and to the external face, and it corresponds to the face facing the support of the light module forming a frame of reference for fixing the light source.
  • the upper face of this rectangular parallelepiped corresponds to the face facing the protective cover of the light module covering in particular the transparent optical surface.
  • At least one lower face of a fixing tab comprises means for positioning the optical element along at least two defined axes. More particularly, these positioning means can be positioning pads configured to ensure the position of the optical element relative to the support along a longitudinal axis, that is to say the main axis of elongation of the fixing lugs, or positioning pins configured to ensure the position of the optical element relative to the support along another axis, by bearing on the support of the light module.
  • the housing is delimited transversely by a longitudinal wall and an internal wall forming a projection from the support, the light module being characterized in that the external face and/or the internal face of the fixing tab comprises at least one positioning rib relative to the support which is able to rest on one of the walls delimiting the corresponding housing to ensure the position of the optical element relative to the support along the transverse axis.
  • positioning ribs make it possible to position the optical element along the transverse axis, and to freeze this position, by tightly guiding the fixing lugs in an appropriate housing of the support. It is notable that the tight guiding is done by contact of the positioning ribs with the walls transversely delimiting the housing.
  • the optical element is positioned overhanging the support of the light module.
  • the support has a transverse edge, which extends longitudinally from one housing to the other. Each housing is delimited longitudinally by this transverse edge.
  • the fixing lugs adapted to cooperate with a housing for positioning and fixing the optical element on the support comprise a part arranged inside the housing and a part which extends longitudinally to the outside of this housing, beyond the transverse edge.
  • the transparent optical surface, extending transversely between these parts of the fixing lugs arranged beyond the transverse edge thus extends cantilevered, that is to say not being supported by the support.
  • the transparent optical surface, or module projection lens can also be described as floating.
  • the module further comprises a reflector fixed on the support to deflect the light rays emitted by the light source towards the optical element, said reflector being arranged to cover the means for covering the fixing lugs of the optical element arranged respectively in a housing of the support.
  • the reflector comprises at least one elastically deformable tab in contact with one of the fixing means of the optical element so as to immobilize said fixing means in the corresponding housing along the vertical axis.
  • the elastically deformable tabs of the reflector include a support wall pressing on the fixing lugs to hold them in their housings by blocking them along the vertical axis. Even more, the deformable tabs elastically tend to push the fixing lugs towards the bottom of their respective housing, so that the positioning pins of the fixing lugs rest on the support in the bottom of their respective housing, immobilizing the optical element along the vertical axis.
  • the light module further comprises a protective cover configured to be fixed on the support so as to surround at least the reflector and the means for fixing the optical element, the reflector comprising at least at least one positioning pin configured to cooperate with a wall of the protective cover and/or the protective cover comprises at least one retaining rib configured to cooperate with a wall of the reflector.
  • the protective cover comprises an upper wall extending in a first plane parallel to the longitudinal axis and the transverse axis and a lower wall extending in a second plane parallel to the longitudinal axis and the transverse axis, the upper wall and the lower wall being connected to each other by longitudinal walls, the protective cover comprising a front wall arranged at a longitudinal end of the upper wall, of the lower wall and the transverse walls, said front wall comprising an opening, the opening being intended to receive the transparent optical surface of the optical element, the upper wall having towards the interior of the light module the at least one rib holding cooperating with the positioning pin of the reflector.
  • the ribs of the protective cover rest on the positioning pins of the reflector.
  • This cooperation makes it possible to achieve linear contact between the cover and the reflector and to ensure precise positioning of the protective cover along the vertical axis, so that the transparent optical surface is correctly arranged in the opening defined in the front wall of the protective cover.
  • This cooperation also makes it possible to reliably generate contact between the protective cover and the reflector.
  • the long transverse sides of the transparent optical surface of the optical element are edges arranged facing one of the support and the other of one face of a protective cover facing the support, the surface transparent optics being able, due to its lateral fixing means, to be held clamped between the support and the protective cover.
  • the protective cover comprises a lower fixing tab extending an edge of the lower wall of the protective cover and at least one upper fixing tab extending an edge of the upper wall of the protective cover , each tab having a window configured to cooperate with an attachment means formed on the support of the light module.
  • Each fixing tab is elastically deformable to form means for fixing the cover to the support by snap-fastening.
  • the fixing tabs are formed projecting from the lower wall and the upper wall, extending longitudinally these walls opposite the transparent optical surface.
  • the protective cover is mounted on the light module by positioning the fixing tabs on either side vertically of the transparent optical surface, then by translating the protective cover along the longitudinal axis, the cover protection thus covering the light module.
  • the protective cover is thus secured by snap-fastening, opposite the transparent optical surface.
  • the support comprises at least one guide rib intended to guide the lower fixing tab.
  • the guide rib ensures the guiding of the fixing tabs when mounting the protective cover on the support, guiding the fixing tabs, as well as the protective cover, towards an attachment means formed on the support.
  • characteristics, variants and different embodiments of the invention can be associated with each other, in various combinations, to the extent that they are not incompatible or exclusive with respect to each other.
  • variants of the invention comprising only a selection of characteristics described subsequently in isolation from the other characteristics described, if this selection of characteristics is sufficient to confer a technical advantage and/or to differentiate the invention from the prior art.
