- TITLE MODULAR AUTOMOTIVE HEADLIGHT BETWEEN LEFT DRIVE AND RIGHT DRIVE
- the invention relates to the field of lighting, in particular lighting for motor vehicles.
- the vehicle lighting function at night with oncoming traffic has a higher cutoff, in accordance with the regulations in force.
- European regulations provide for an upper horizontal cutoff 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 cutoff than the other half. More particularly, for right-hand drive countries, i.e. 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, i.e. where the driving position is to the right of the vehicle, the left half of the light beam is greater than the right half. US regulations provide, in particular, for a flat upper horizontal cut-off, that is to say without an oblique portion. This means that automotive headlamps have to be configured differently depending on these territories.
- the published patent document US 2018180246 A1 discloses an automotive headlight comprising a screen arranged in the optical path of the light rays forming a cut-off light beam, the transmittance of which is locally variable, such as for example a liquid crystal screen, commonly designated by the acronym LCD ("Liquid Crystal Display"). More particularly, the pixels of this screen can be specifically controlled to achieve the above-mentioned upper horizontal cuts for left-hand drive and right-hand drive, respectively, i.e. with opposing central oblique portions. In other words, this teaching provides for an electrically controlled configuration of the projector for different regulations, in particular conducted at left and right hand drive.
- the presence of the screen, the transmittance of which is locally variable is expensive and also has the drawback of generating significant light losses, due to the limited maximum transmittance.

- the inclined lateral edges of the surfaces capable of being illuminated of the first and second complementary optical systems are adjacent to the optical axis and arranged laterally on either side of said optical axis.
- the optical part of each of the first and second complementary optical systems is a diopter with an input face of light emitted by the corresponding light source, a face of reflection of said light and a face of output of said light, forming the surface suitable for being illuminated.
- the optical part of each of the first and second complementary optical systems comprises a reflecting surface forming the surface capable of being illuminated.
- the main optical system comprises a light source with a main direction of emission of light rays directed upwards and a collector with a reflecting surface in the form of a cap capable of receiving the light rays and with a lower rear edge adjacent to the optical axis.
- the surfaces capable of being illuminated of the first and second complementary optical systems are, on the optical axis, adjacent to the rear and lower edge of the reflective surface of the collector.
- the projection device comprises a focus located on the optical axis at the level of the lower rear edge of the reflective surface of the collector or at the front of said edge.

- Such a module is intended to be mounted in a box closed by a glass, optionally with one or more other light or lighting modules, in order to form a projector.
- 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 cut-off, commonly referred to as "code” (or “ low-beam ”in English) and a lighting function without horizontal cut-off, commonly referred to as“ road ”(or“ high-beam ”in English).

- the second complementary optical system 14 forms a complementary light beam located to the left of the optical axis with an oblique lateral cut adjacent to the optical axis, so as to form a projection upwards to the left of the optical axis, in accordance with the regulations for driving on the left.
- the lighting module 2 comprises a projection device 22, in this case a lens, capable of imaging and projecting the illuminated reflecting surface of the collector 8 of the main optical system 4, as well as a illuminated surface of the optical part 20.1 or 20.2 of the first or second complementary optical systems 12 and 14.
- a projection device 22 in this case a lens, capable of imaging and projecting the illuminated reflecting surface of the collector 8 of the main optical system 4, as well as a illuminated surface of the optical part 20.1 or 20.2 of the first or second complementary optical systems 12 and 14.
- the lighting module 2 may include one or more additional optical systems 24 configured to form light beams with upper horizontal cutoff supplementing the main light beam produced by the main optical system 4.
- Figures 2 and 3 are two perspective views of 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 for 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. Reflection faces
- 20.1.2 and 20.2.2 are rear faces of optical parts 20.1 and 20.2 and have a slightly curved and convex profile in a vertical plane.
- the output 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 (FIG. 1). They present in a horizontal plane a concave curved profile corresponding to the profile of the adjacent rear and lower edge of the reflecting surface of the collector 8 of the main optical system 4 (FIG. 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.
- the complementary light beam imaging such an illuminated face will thus have a corresponding shape, that is to say thin vertically. This image will be inverted when the projection device 22 passes (FIG. 1).
- the internal lateral edge with respect to the optical axis (passing between the two optical parts 20.1 and 20.2, that is to say in the center the common optical part 20) designated by the reference signs 20.1.3.1 and 20.2.3.1 is inclined with respect to the vertical, for example by an angle of between 45 ° and 75 ° (corresponding to an inclination of between 45 ° and 15 ° with respect to the horizontal), so as to form the oblique lateral cut-off of the corresponding complementary light beam.
- FIG. 4 is a schematic view in vertical longitudinal section of the lighting module of FIG. 1.
- the section passes through the optical axis 10 while for the complementary optical devices 12 and 14 the section is offset perpendicularly to the section plane of the main optical system 4 and optionally passes through one of said complementary optical systems and the corresponding light source.
- the light source 6 illuminates the reflecting surface of the collector 8, from the lower rear edge 8.1 to the front edge 8.2 of said reflecting surface.
- the projection device 22 comprises a focal point 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 along the rear and bottom edge 8.1 is vividly imaged. to achieve a clean top horizontal cut. To image the illuminated reflecting 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, more preferably still greater than 60mm.
- the focal length is advantageously less than 100 m.
- the complementary optical system 12 or 14 With the complementary optical system 12 or 14, one can observe the path of the rays emitted by the corresponding light source 16 or 18. These are potentially refracted to the diopter formed by the entry 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 angle of incidence is greater than the limit angle of refraction, and then potentially refracted when passing through the diopter formed by the exit face 20.1.3 or 20.2.3 then forming an illuminated surface.
- This illuminated surface is advantageously adjacent to the optical axis 10 and to the lower rear edge 8.1 of the reflecting surface of the collector 8. Therefore, 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 with sharpness, this which allows a complementary light beam to be produced with sharp cuts.
- Figure 5 illustrates the collector 8 of the main optical system 4 ( Figures 1 and 4).
- the left view is a perspective view showing the cap shape of the collector, advantageously with an elliptical or parabolic profile, advantageously of revolution, at least as a first approximation, around an axis corresponding to the optical axis 10.
- the view 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 indeed causes an inversion of the image, explaining that the image of the lower rear edge 8.1 of the reflective surface actually forms the upper horizontal edge of the projected image. Similarly, the leading edge 8.2 of the reflective surface forms the lower edge of the projected image. It can be observed that the light is concentrated in the middle of the surface, near the lower rear edge.
- 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 a generally flat or straight upper horizontal cutout 26.1. 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 however be noted that this upper horizontal cut-off 26.1 could have a non-flat profile when the lower rear edge 8.1 of the reflecting surface of the collector 8 is not flat.
- the image of the main light beam 26 comprises a lower U-shaped cut 26.2, less sharp than the upper horizontal cut 26.1, formed by the front edge 8.2 of the reflecting surface of the collector 8 ( Figures 4 and 5).
- the first complementary optical system 12 FIG. 1
- the combination of the main light beam 28 with the first additional light beam 28 corresponds to a so-called "code" cut-off lighting function
- Figures 7 and 8 illustrate a lighting module according to a second embodiment of the invention.
- the reference numbers of the first embodiment are used to designate identical or corresponding elements, these numbers however being increased by 100. Reference is also made to the description of these elements in relation to the first embodiment. Specific numbers between 100 and 200 are used to designate specific items.
- FIG. 7 illustrates in perspective and schematically a lighting module 102 similar to that of the first embodiment. It differs from it essentially by the construction of complementary optical systems 112 and 114, the optical parts 120.1 and 120.2 of which are no longer dioptric parts but indeed reflectors. Similar to the first embodiment, the main optical system 104 produces a main light beam with an upper horizontal cutoff, preferably flat, and the complementary optical systems 112 and 114 produce complementary light beams located to the right and to the left of the optical axis. , respectively, with an oblique lateral cut adjacent to the optical axis.
- Figure 8 is a perspective view of the main optical system 104 and the first and second complementary optical systems 112 and 114 respectively.
- the collector 108 of the main optical system 104 comprises a reflecting surface in the shape of a cap with a lower rear edge 108.1 adjacent to the optical axis 110 and a front edge 108.2 which corresponds in this case to a truncation of the cap by an upper plane close to a horizontal orientation.
- the light source 106 is configured to illuminate this reflecting surface, the latter being imaged by the projection device 122 (FIG. 1) to form the main beam with an upper horizontal cut-off formed by the essentially sharp image of the lower rear edge 108.1 of the reflective surface in question. The more or less clear image of the leading edge 108.2 then forms the lower limit of the main light beam.
- the reflectors 120.1 and 120.2 forming the optical parts of the first and second complementary optical systems 112 and 114 are adjacent to the lower rear edge 108.1 of the reflecting surface of the collector 108 of the main optical system 104.
- Each of the reflectors 120.1 and 120.2 comprises a first reflecting surface 120.1.1 or 120.2.1 extending substantially horizontally from the lower rear edge 108.1 of the reflective surface of the collector 108 of the main optical system 104, and a second reflective surface 120.1.2 or 120.2.2 extending substantially vertically from the first reflecting surface 120.1.1 or 120.2.1.
- Each of the second reflecting surfaces 120.1.2 or 120.2.2 presents in a horizontal plane a concave curved profile of greater mean radius than the rear and lower edge 108.1 of the reflecting surface of the collector 108 of the optical system main 104.
- the reflectors 120.1 and 120.2 are configured to collect the light emitted by the light sources 116 and 118 respectively so as to illuminate the second reflecting surfaces 120.1.2 and 120.2.2 respectively.
- Each of the second reflecting surfaces 120.1.2 or 120.2.2 extends horizontally with an average width L greater than a multiple, for example 5 or 10, at the average height H.
- Each of these surfaces has an inclined lateral edge 120.1.2.1 or 120.2.2.1 adjacent to the optical axis 110, so as to form an oblique lateral cut-off edge of the corresponding complementary light beam.
- the projection device 122 images these illuminated reflecting surfaces to form the complementary light beams similar to the complementary light beams 28 and 30 of the first embodiment (FIG. 6).
- the light source of the main optical system and the light sources of the complementary optical systems can be arranged on a common support, due to their proximity and to the fact that they all light in the same direction.
- the complementary optical systems can take various forms, since they are configured to form alternative complementary beams with opposite oblique lateral cuts able to form with the main light beam with upper horizontal cutoff , advantageously of flat profile, an upper horizontal cut with a projection in the center, in accordance with the regulations in force in particular in Europe.
- the main optical system can also take various forms, as long as it produces a light beam with a higher horizontal cutoff, preferably flat.
- the invention which has just been described is advantageous in that it makes it possible to produce a single lighting module for a switching lighting function of the "code" type (or "low-beam” in English) compatible for different regulations, such as European regulations with specific step for left-hand drive and right-hand drive, and American regulations without step. Compliance with the regulations to be observed is then carried out by specific activation of one or none of the complementary optical systems.
