Definitions

  • the nighttime automobile lighting function with oncoming traffic has a higher cut-off, in accordance with current regulations.
  • European regulations provide for an upper horizontal cut-off with an oblique portion in the center of the beam, so that a left or right half of the light beam has a lower horizontal cut-off than the other half. More particularly, for right-hand drive countries, that is to say where the driving position is on the left of the vehicle, the left half of the light beam is less than the right half. Conversely, in right-hand drive countries, that is to say where the driving position is to the right of the vehicle, the left half of the light beam is greater than the right half.
  • the American regulations provide, in particular, for a flat upper horizontal cutoff, that is to say without an oblique portion. This means that automotive headlights must be configured differently depending on these territories.

  • the measures of the invention are interesting in that they make it possible to make the lighting module with upper horizontal cut-off lighting function of the “code” type (“low-beam” in English) compatible with different regulations and sides driving (left-hand drive and right-hand drive), in a simple, economical and compact way.
  • FIG. 1 is a perspective view of a lighting module according to a first embodiment.
  • lighting module we mean a unitary assembly, that is to say where all the optical parts are assembled and positioned with each other so as to be able to provide one or more lighting or light signaling functions.
  • Such a module is intended to be mounted in a housing closed by a glass, possibly with one or more other light or lighting modules, with a view to forming a spotlight.
  • the lighting module 2 comprises several optical systems capable of forming different lighting beams of one or more lighting functions, in this case a lighting function with upper horizontal cutoff, commonly referred to as "code” (or “code”). low-beam” in English) and a lighting function without horizontal cut-off, commonly referred to as “road” (or “high-beam” in English).
  • the lighting module 2 comprises a main optical system 4 capable of forming a main light beam with upper horizontal cut-off, intended to perform a lighting function designated “code”.
  • the main optical system 4 essentially comprises a light source 6 and a collector 8 with a reflective surface in the shape of a cap and configured to receive and reflect along the optical axis 10 the light rays emitted by said light source.
  • the lighting module 2 also includes two complementary optical systems 12 and 14, arranged under the optical axis 10 and configured to form light beams complementary to the main light beam formed by the main optical system 4, and this in an alternative manner.

  • THE figures 2 and 3 are two perspective views of the optical parts 20.1 and 20.2 of the first and second complementary optical systems 12 and 14 ( figure 1 ). These two optical parts are made of transparent or translucent materials and form diopters, each with an entry face, a reflection face and an exit face of the light emitted by the associated light source. Entrance faces 20.1.1 and 20.2.1 present in a vertical plane a convex curved profile arranged opposite the light sources 16 and 18 respectively.
  • the reflection faces 20.1.2 and 20.2.2 are rear faces of the optical parts 20.1 and 20.2 and have a slightly curved and convex profile in a vertical plane.
  • the exit faces 20.1.3 and 20.2.3 are front faces of the optical parts 20.1 and 20.2, adjacent to the reflecting surface of the collector 8 of the main optical system 4 ( figure 1 ).

  • each of these faces has an average width L which is greater than a multiple of the average height H, for example greater than 5 times the average height H.
  • complementary light beam imaging such an illuminated face will thus have a corresponding shape, that is to say vertically thin. This image will be inverted as the projection device 22 passes ( figure 1 ).

  • FIG. 4 is a schematic view in vertical longitudinal section of the lighting module of the figure 1 .
  • the section passes through the optical axis 10 while for the complementary optical devices 12 and 14 the section is offset perpendicular to the cutting plane of the main optical system 4 and passes optionally through one of said complementary optical systems and the corresponding light source.
  • the light source 6 illuminates the reflective surface of the collector 8, from the lower rear edge 8.1 to the front edge 8.2 of said reflective surface.
  • the projection device 22 comprises a focus 22.1 located on the optical axis 10, at the level of the lower rear edge 8.1 or at a position further forward, however still at the level of the collector 8, ideally over a first half of the length of the collector along the optical axis. With a certain depth of field, this allows the projection device 22 to image the reflective surface of the collector 8 while it is illuminated, where the area of the reflective surface located along the rear and lower edge 8.1 is imaged with clarity in order to achieve a clear upper horizontal cut. To image the illuminated reflective surface, the main optical system 4 including the projection device 22 must be stigmatic.
  • the optical device 22 advantageously has a large focal length, more advantageously still a large geometric aperture.
  • the focal length is greater than 40mm, preferably greater than 50mm, even more preferably greater than 60mm.
  • the focal length is advantageously less than 100m.
  • the path of the rays emitted by the corresponding light source 16 or 18 can be observed. These are potentially refracted at the diopter formed by the entrance face 20.1.1 or 20.2.1, then they are reflected by the reflection face 20.1.2 or 20.2.2, advantageously by the principle of total reflection when the angel of incidence is greater than the limiting angle of refraction, and then potentially refracted as the diopter formed by the exit face 20.1.3 or 20.2.3 then forming an illuminated surface.

  • the illuminated surface 20.1.3 or 20.2.3 is adjacent to the focus 22.1 of the projection device 22 , or at least close to it. This illuminated surface is then imaged clearly, this which makes it possible to create a complementary light beam with clear cuts.
  • FIG. 5 illustrates the collector 8 of the main optical system 4 ( figures 1 And 4 ).
  • the view on the left is a perspective view showing the shape of the cap of the collector, advantageously with an elliptical or parabolic profile, advantageously of revolution, at least in first approximation, around an axis corresponding to the optical axis 10.
  • the view on the right shows the reflective surface when illuminated by the light source, seen from the front of the projection device 22 ( figures 1 And 4 ). This in fact causes an inversion of the image, explaining that the image of the lower rear edge 8.1 of the reflective surface in fact forms the upper horizontal edge of the projected image. Similarly, the front edge 8.2 of the reflective surface forms the lower edge of the projected image.
  • the light is concentrated in the middle of the surface, near the bottom rear edge.
  • the fact that the focus 22.1 of the projection device is on the optical axis and close to, or adjacent to the lower rear edge 8.1 of the reflective surface of the collector 8 means that the central part of the reflective surface, close to said edge, will be imaged with greater clarity. Under these conditions, the upper horizontal cutoff of the main light beam will be sharper in the center than on the sides.
  • FIG. 6 schematically illustrates the images of the main and complementary light beams.
  • the H axis corresponds to the horizontal direction passing through the optical axis and the V axis corresponds to the vertical direction also passing through the optical axis.
  • the image of the main light beam 26 includes an upper horizontal cutoff 26.1 that is generally flat or straight. It is formed by the image of the rear and lower edge 8.1 of the reflecting surface of the collector 8 of the main optical system 4 ( figures 4 and 5 ). It should be noted, however, that this upper horizontal cutoff 26.1 could have a non-flat profile since the lower rear edge 8.1 of the reflective surface of the collector 8 is not planar.
  • the image of the main light beam 26 includes a lower U-shaped cutoff 26.2, less sharp than the upper horizontal cutoff 26.1, formed by the front edge 8.2 of the reflecting surface of the collector 8 ( figures 4 and 5 ).
  • These four cuts are formed by the lateral, upper and lower edges of the illuminated surface formed by the exit face 20.1.3 of the corresponding diopter 20.1 ( figure 2 ) it being understood that there is an inversion of the image, corresponding to a rotation of 180° around the optical axis 10.
  • the image of the second complementary light beam 30, located to the left of the optical axis 10 is produced by the second complementary optical system 14 ( figure 1 ) located to the right of the optical axis. It similarly comprises an oblique lateral cutoff 30.1 adjacent to the optical axis 10, an exterior lateral cutoff 30.2 and upper 30.3 and lower horizontal cuts 30.4.
