Definitions

  • the invention relates to lighting devices such as headlamps for motor vehicles.
  • the first provides illumination of the entire width of the road in front of the vehicle.
  • the second provides lighting of the lane in which the vehicle is located and reduced lighting of the lane located next to it and in which vehicles are likely to drive in the opposite direction. In this way, the occupants of the latter are not dazzled.
  • the dipped beam function in its most usual form does not in certain cases make it possible to sufficiently illuminate the side of the road located beyond this adjacent lane. But this is a source of danger. For example, if a pedestrian located on this verge is about to cross the road, he will not be visible soon enough to the driver.
  • an adaptive traffic light function which makes it possible to illuminate certain parts of the scene situated in front of the vehicle and in particular the roadside situated beyond the adjacent lane from a great distance and selectively.
  • an observation device analyzes the scene and selects the zones which must be illuminated.
  • a lighting system making it possible to implement this operation is presented in the document EP-2 532 950 . It comprises a first module intended to form vertical strips and a second module intended to form horizontal strips, each of these two modules being provided with its own light sources and its own optical device for projecting the light beam towards the stage.
  • the document WO2012/083331 describes a lighting module comprising secondary light sources cooperating with an optical guide to form specific light distributions.
  • An object of the invention is to overcome these drawbacks and therefore to reduce the volume of the lighting system and the number of system adjustments to be made.
  • the lighting system comprises a lighting module capable on its own of forming the vertical light strips and the horizontal light strips. It is therefore not necessary to provide several lighting modules, which contributes to limiting the size of the lighting system.
  • the lighting system only comprises a single lighting device.
  • the optical means are common to the two sets of light sources. Therefore, only these optical means must be adjusted in the lighting system, which makes it possible to reduce the number of adjustment operations. Adjusting one optical device relative to another is thus avoided.
  • the light sources each comprise a face of generally rectangular shape for emitting light.
  • Such light sources make it possible to form light spots in the form of a rectangular light strip.
  • the light sources of each of the first and second sets are respectively aligned on first and second substantially planar supports, such as printed circuit boards.
  • This arrangement of the light sources of the first and second sets allows the light spots to be arranged in a matrix manner to effectively cut out the scene to be selectively illuminated. If necessary, the first and second supports extend substantially along non-parallel planes.
  • the guide means are formed by light guides, and for example in the general shape of a rectangular parallelepiped, positioned on at least part of the light sources of the first set and each capable of receiving at least part of the light emitted by the light sources of the second set, each light guide having at least one extraction face, for example substantially parallel to a plane passing through the light sources of the first set, this extraction face having light extraction means capable of directing at least one part of the light emitted by the light sources of the second set out of the guide.
  • the secondary optical means having a zone of focusing, these secondary optical means are arranged so that this focusing zone is advantageously arranged at the level of said extraction face.
  • each light source of the second set penetrates inside a light guide, and the extraction means allow it to come out of the guide to form the light spots having a shape of light strip substantially parallel to the second direction.
  • the number of light sources in the first set is identical to the number of light sources in the second set.
  • the light guides are positioned on the light sources of the first set so as to cover all of said light sources of said first set. This characteristic makes it possible to increase the homogeneity of the light beam formed by the lighting module.
  • the number of light sources of the first set is distinct, in particular greater than the number of light sources of the second set.
  • the light guides are positioned on the light sources of the first set so as to cover only a subset of light sources of said first set. This characteristic offers the advantage of distributing more light on one side of the light beam formed by the lighting module than on the other side.
  • the light sources of the first set are arranged so that the light emitted by these sources passes through the extraction means of the light guides, the extraction means being arranged so as not to deviate this light emitted by the light sources of the first set.
  • the extraction means are formed by striations, or as a variant prisms, pyramids or graining, provided on the extraction face of each guide.
  • the extraction means are thus produced by simple means which do not increase the size in the lighting system.
  • the extraction faces are lower faces of the guides.
  • the light sources of the first and second sets are capable of emitting white light.
  • the extraction means are formed by a layer of a wavelength converter material.
  • the light sources of the first set and of the second set are capable of emitting substantially monochromatic light, the layer being capable of transforming this substantially monochromatic light into White light.
  • the extraction faces are lower faces of the guides. This characteristic offers the advantage of obtaining an identical light-emitting surface for the light sources of the first and second assemblies which is substantially matrix, that is to say whose pixels have sharp edges, from the point of view of the secondary optical means.
  • the extraction faces are upper faces of the guide. This characteristic offers the advantage of being able to easily determine the shape of the secondary optical means for positioning the focusing zone.
  • the light sources of the second set emit substantially monochromatic light rays
  • the light rays encountering the layers of wavelength converter material of the light guides are absorbed and re-emitted by these layers in the form of white light, and this perpendicular to the layers, i.e. outside the guides.
  • the first direction is perpendicular to the second direction.
  • the light spots formed by the light sources of the first and second sets intersect along rectangles, which makes it possible to produce a effective mesh of the scene to be selectively illuminated.
  • the optical means of the module include optical projection means on the road and optical reflection means for directing the light emitted by the light sources towards the optical projection means.
  • the optical reflection means comprises a reflector, for example a plane.
  • the optical projection means comprises a projection lens capable of receiving light from each source.
  • the module comprises a screen forming an obstacle to the direct transmission of light from the light sources of the module to the optical projection means of the module.
  • the optical means are thus formed by simple means.
  • the lighting system further comprises at least one control member able to selectively control the switching on, the switching off or the variation of the light intensity emitted by each light source of the lighting system.
  • each set are each formed by a single chip light emitting diode.
  • each set is formed by a multi-chip light-emitting diode, each chip forming one of the light sources.
  • the lighting system comprises at least first and second lighting modules, the first module forming light spots, extending substantially along the second direction, in particular substantially parallel to this second direction, spaced apart transversely to form transverse spacings, the second module forming light spots extending substantially along the second direction, in particular substantially parallel to this second direction, at least partially covering the transverse spacings.
  • a method for controlling a lighting system the lighting system being as defined above, when a body not to be illuminated, for example a motor vehicle, is deactivated in the lighting system the light sources intended to form the light spots for illuminating the area covering the body.
  • the lighting system thus produces selective lighting making it possible to turn off the light sources capable of illuminating, for example, a vehicle traveling in the opposite direction on an adjacent lane.
  • This lighting system 1 comprises a lighting module 2.
  • This lighting module 2 comprises first 4 and second 5 sets of light sources, a cover or screen 6, and secondary optical means 8, 10, comprising here an optical reflection means 8 and an optical projection means 10.
  • a light source of the first set will be designated by the reference 4n and a light source of the second set by the reference 5n.
  • the optical reflection means 8 is arranged to direct the light emitted by the light sources 4n, 5n towards the optical projection means 10, and the latter projects the light in front of the vehicle.
  • the optical reflection means 8 comprises a plane reflector and the optical projection means 10 comprises a projection lens capable of receiving light from each source 4n, 5n.
  • the cover or screen 6 is placed in the module 2 so that it forms an obstacle to the direct transmission of light light sources of the first 4 and second 5 sets of the module 2 to the optical projection means 10.
  • the light sources of the first set 4 comprise, in this first embodiment, light-emitting diodes emitting white light. They are aligned in a direction parallel to the X axis and carried by a first printed circuit board 12 common to all the 4n sources.
  • This first plate 12 forms a first substantially planar support for the light sources of the first set 4.
  • the first plate 12, the optical reflection means 8 and the optical projection means 10 are arranged so that the image of the first plate 12 by reflector 8 is substantially included in the focal plane of lens 10.
  • the light sources of the first set 4 are arranged to produce lighting directed upwards with their vertical optical axis.
  • they each have a face of generally rectangular shape emitting light in a plane perpendicular to this optical axis, the long sides of the rectangles being substantially parallel to the axis Y.
  • Each face emitting light has an area equal to example at 1 mm 2 .
  • the number of 4n sources can be varied. It is greater than or equal to three and the highest possible, each source 4n producing one of the light spots forming the lighting. There are as many light spots formed as there are 4n light sources.
  • the light sources of the first set 4 each have a side parallel to a direction of alignment of the light sources 4n.
  • the two opposite sides of the emission face of each light source 4n are parallel to an optical axis 13 of the lens 10.
  • the light sources of the second set 5 are similar to those of the first set 4. They differ, however, in that they are arranged to produce illumination in a direction substantially parallel to the X axis and in that they are aligned along a direction parallel to the Y axis. These 5n light sources are carried by a second printed circuit board 14 common to all the 5n sources. This second plate 14 forms a second substantially planar support for the light sources of the second set 5.
  • the module 2 also comprises means primary optics 16 formed by light guides in the general shape of a rectangular parallelepiped, positioned on the light sources of the first set 4.
  • the light guides 16 have an elongated shape in a direction parallel to the direction X.
  • the light guides 16 are made of a plastic with an optical index greater than that of air and transparent to light in the visible range. The optical index is preferably greater than 1.45 so as to be able to carry out efficient guiding of the light.
  • the guides 16 are capable of receiving part of the light emitted by the light sources of the second set 5.
  • the lighting module 2 comprises as many light guides 16 as the module 2 comprises light sources of the second set 5, and the light guides 16 are aligned parallel to the Y axis.
  • the light guides 16 are spaced two by two by an air gap (not shown) with a thickness approximately equal to 10 ⁇ m, so as to separate the guides 16 from each other.
  • At least some of the light guides 16 have a curved end 17 intended to adapt to the position of the light sources of the second set 5 on the second printed circuit board 14. This reduces the positioning constraints of the sources 5n on the second plate 14, the paths of the light guides 16 can be relatively complex to adapt to the position of the light sources 5n.
  • Each light guide 16 has an extraction face 18 substantially parallel to the first plate 12.
  • This extraction face 18 is here formed by the lower face of the guide 16, and has light extraction means 20 capable of direct part of the light emitted by the light sources of the second set 5 out of the guide 16.
  • These extraction means 20 are here formed by grooves 22 provided on the extraction face 18 of each light guide 16.
  • These serrations 22 here form on the extraction face 18 of each guide 16 a succession of prisms with opening angles approximately equal to 90°.
  • the striations 22 are located opposite the light sources of the first set 4. It will be seen below that the light guides 16 provided with light extraction means 20 are of interest for the use which is made of the system of lighting 1.
  • the lighting system 1 further comprises at least one control member 23 capable of selectively controlling the switching on, the switching off or the variation of the light intensity emitted by each light source 4n, 5n of the lighting system. lighting 1.
  • the light emitted from the rectangular light-emitting faces of the sources of light of the first set 4 passes through the light guides 16 without it being deflected by them.
  • the light then reaches the plane mirror 8 forming the optical means of reflection, which reflects it towards the lens 10 forming the optical means of projection.
  • the light is then projected onto the scene in front of the vehicle.
  • the optical means 8, 10 form, from the light emitted by the light sources of the first set 4, a light spot per source of light 4n, each spot having the shape of a light band of rectangular shape substantially parallel to the same first direction, which is in this case the vertical direction.
  • These vertical light spots 24 are shown in figure 8 .
  • part of the light encounters the striations 22 and is reflected in a direction substantially parallel to the direction Z. This light then leaves the light guides 16 and goes towards the plane mirror 8, to be reflected towards the lens 10, and to finally be projected onto the scene in front of the vehicle.
  • the grooves 22 are made over a great length of the light guides 16, the light being reflected by these grooves 22 over the whole (or almost the whole) length. More particularly, the streaks are made over a distance equivalent to the distance between the first and last light sources of the first set 4 aligned.
  • the light guide means 16 are therefore arranged to form, in cooperation with the secondary optical means 8, 10 and from the light emitted by the light sources of the second set 5, a light spot per light source 5n, each spot having the shape of a light band of rectangular shape substantially parallel to a second direction not parallel to the first, this second direction being in this case horizontal and substantially parallel to the axis X. Since the light guides 16 are positioned on the light sources of the first set 4, and that the streaks 22 are placed opposite the light sources of the first set 4, the vertical spots 24 and the horizontal spots 26 overlap.
  • the horizontal light spots 26 are shown in figure 9 . It can be seen in this figure that the horizontal light spots are spaced apart from each other transversely to form transverse spacings 28. These spacings 28 form areas of the scene in front of the vehicle which are not illuminated. They are generated by the air gaps spacing the light guides 16. In order to be able to illuminate these areas, provision can be made for the lighting system 1 (the lighting module 2 described in the foregoing forming a first lighting module) is provided with a second lighting module (not shown), similar to the first and able to form horizontal light spots covering at least partially the transverse spacings 28.
  • the lighting system 1 is therefore capable of fictitiously cutting out the scene in front of the vehicle according to a matrix layout.

  • light guides 116 of a lighting system differ from those described above in that they further comprise a layer of wavelength converter material 125 provided on an upper face 130 of each light guide 116.
  • This layer 125 comprises for example a phosphorescent or luminescent material, such as YAG (Yttrium Aluminum Garnet) crystals doped with rare earths, ZnS, etc. Thanks to the layer of wavelength converter material 125, it is possible to replace the white light-emitting diodes, forming the light sources of the first 4 and second 5 sets, by light sources emitting a substantially monochromatic light beam, such as laser diodes. In addition, the position of the layer 125 away from the light sources of the first set 4 makes it possible to form larger light spots and having more blurred contours. In this way, the light beam emerging from the lighting system does not have a high contrast zone.
  • light guides 216 of a lighting system differ from those of the first embodiment in that, on the one hand, the extraction faces 218 of each guide 216 do not have grooves but a layer of wavelength converter material 225, and, on the other hand, the light sources of the first 4 and second 5 assemblies are formed by sources emitting substantially monochromatic light and not white light. In this way, the light emitted by the light sources of the second set 5 propagating in the light guides 216 encountering the layer 225 is absorbed by the latter. It is then re-emitted by layer 225 in the vertical direction, towards mirror 8 forming optical reflection means to form horizontal light spots.

  • This light guide 316 differs from those previously described in that it is in one piece. It can therefore replace all the light guides as described in the other embodiments.
  • This light guide 316 also has longitudinal orifices 317 extending in directions substantially parallel to the axis X, along the entire length of the guide 316. These orifices 317 make it possible to separate the guide 316 into several ducts 319, each of these ducts 319 being capable of receiving light emitted by one of the light sources of the second set 5.
