Definitions

  • the invention relates to the field of light signaling and lighting, in particular for motor vehicles.
  • optical guides In the field of lighting and signaling of motor vehicles, it is increasingly common to use optical guides. Indeed, these have the advantage of being able to take very varied geometric shapes and to provide an illuminating surface in inaccessible areas of a lighting and/or signaling device. This is particularly interesting in the current context where automobile manufacturers seek to give their vehicles their own signature, in particular by offering complex shapes to lighting and/or signaling devices.
  • the patent document US 2014/0177278 A1 discloses a plate-shaped light guide with two opposing main faces. Light produced by light sources enters the guide via one of the side faces. The light rays then propagate by successive reflections on the two main faces of the guide. The latter in fact form diopters with the ambient air and thus allow rays incident at an angle greater than the limiting angle of refraction to undergo so-called total reflection.
  • One of the main faces of the guide includes microstructures in the form of hollows or bumps also forming diopters with the ambient air. The rays propagating essentially along the extent of the guide which meet one face of the hollows undergo a total reflection directed towards the other main face. The latter is then the exit face of the guide.
  • the light emerging from the sheet may present homogeneity defects.
  • the invention aims to overcome at least one of the disadvantages of the aforementioned state of the art. More particularly, the invention aims to enable the production of light in a homogeneous manner, in particular in the context of light signaling with potentially complex shapes.
  • the subject of the invention is an optical guide as described in claim 1.
  • optical guide By optical guide, the present application aims at a transparent or translucent part inside which light rays propagate in a controlled manner from one of the ends of the guide, called the entry face, to at least one face of exit.
  • the propagation of light in a controlled manner is generally carried out by successive total reflections on various reflection faces internal to the optical guide.
  • variable shape of the rib comprises an inclination of the rib relative to a direction transverse to the main direction, passing through the center of the guide portion and the rib at the level of adjacency with said portion as well that preferably the thickness e of the rib.
  • the thickness of said rib varies by a value greater than 50% of the average value of said thickness and/or the inclination of the rib varies more than 20°.
  • the guide comprises at one end a light entry face, the shape of the rib being variable so as to promote the exit of light as the distance relative to said face increases, and thus to compensate for a decrease in the quantity of light passing through the guide portion.
  • the thickness of the rib increases with the distance relative to the entry face and/or the inclination of the rib decreases with the distance relative to the entry face.
  • the guide portion has an average diameter in cross section, the rib having a maximum thickness less than 70% of said diameter.
  • the maximum thickness of the rib is less than 60% of the average diameter of the guide portion.
  • the average diameter of the guide portion is constant over more than 90% of the length of said portion.
  • the guide portion has an average diameter in cross section and the optical guide extends in the main direction over a length greater than 20 times said diameter.
  • variable shape of the rib presents variations over more than 80% of the length of the guide.
  • the sheet is unitary and integral with the rib and the guide portion.
  • the guide portion is a first guide portion and the rib is a first rib
  • the optical guide comprising a second guide portion and a second rib adjacent to the sheet.
  • the sheet comprises two main and opposite faces, at least one of said faces comprises zones with means for emitting light from one of said faces, forming lighting zones.
  • the light output means on one of the main faces of the sheet comprise graining.
  • the graining has an average grain size greater than and/or less than 40 ⁇ m.
  • the invention also relates to a light module comprising: at least one light source; at least one optical guide capable of being supplied with light from at least one light source; remarkable in that the at least one optical guide conforms to the invention.
  • the module further comprises a mask placed against the sheet, said mask comprising windows aligned with the zones provided with light output means.
  • the mask is made of transparent or translucent material and comprises a paint delimiting the windows.
  • the windows of the mask have grained faces facing the sheet.
  • the invention also relates to a lighting device for a motor vehicle, comprising at least one light module for light signaling; remarkable in that the at least one light module conforms to the invention.
  • the light device is a projector and further comprises at least one light lighting module.
  • the guide portion(s) extend mainly transversely and the sheet extends from said guide portion(s) mainly longitudinally towards the front, the lighting zones of the sheet being located on an upper main face of said sheet.
  • the invention also relates to a light module comprising: at least one light source; at least one optical guide with a tubular and rounded guide portion, forming with the external environment a tubular and rounded diopter, said portion being capable of guiding light along the main direction by successive reflections on the diopter, and an tablecloth optically connected to said portion and capable of being supplied with light by said portion and of forming lighting zones; and a mask disposed against the sheet, said mask comprising windows aligned with the lighting zones.
  • the mask is made of transparent or translucent material and includes a paint delimiting the windows.
  • the windows of the mask have grained faces facing the sheet.
  • the lighting zones extend beyond the corresponding windows so as to avoid parallax defects.
  • the light output means on one of the main faces of the sheet comprise graining.
  • the graining has an average grain size greater than 20 ⁇ m and/or less than 40 ⁇ m.
  • the measures of the invention are interesting in that they make it possible to carry out a light signaling function of potentially complex shape while ensuring good light homogeneity according to different observation points at the front of the light module.
  • Varying the shape of the rib along the guide portion makes it possible to modulate the quantity of light according to light needs. In other words, this modulation not only makes it possible to compensate for the progressive reduction in light along the guiding portion but also to adjust the quantity of light distributed according to needs. For reasons in particular of homogeneity, it is in fact possible that the quantity of light required along the guide portion is not constant. Modulation by the shape of the rib thus gives great freedom, particularly for complex shapes and configurations.
  • varying the shape of the rib in terms of its thickness and in terms of its inclination also makes it possible to form profiles on the two opposite faces of the optical guide, at the level of the rib, particularly favorable to the production of said guide by plastic injection, particularly in terms of demoulding. Demoulding is particularly delicate for extended and thin parts, typically extended over more than 150mm and with an average thickness of less than 7mm, which is precisely the case in the embodiment below.
  • Graining the exit face of the sheet is useful for letting out light and can be done during molding.
  • FIG. 1 illustrates a headlight 2 for a motor vehicle, in this case a left headlight, it being understood that the right headlight is symmetrical to the left headlight with respect to a longitudinal and vertical plane of symmetry.
  • the projector 2 comprises a housing 4 forming a cavity open towards the front, this being closed by a glass (not visible).
  • the cavity contains two lighting modules 6 and 8 for so-called code (in English “low-beam”) and road (in English “high-beam”) functions. It also contains a light module 10 of the daytime running light or DRL type (acronym for the English expression “Daytime Running Light”).
  • the cavity of the headlight 2 further comprises a signaling light module 12 located in this case between the daytime running light module 10 and the code and highway modules 6 and 8. This is a style light module intended to be permanently lit.
  • the figure 1 As is visible in the figure 1 , it comprises three light strips extending essentially transversely and arranged side by side in a longitudinal direction, so as to be able to be seen and identified by an observer located at the front of the vehicle, in a sector of ⁇ 45° per relative to the longitudinal axis of the vehicle, at an angle in a vertical plane of +20° relative to the horizontal.
  • the projector 2 comprises a mask 14 with openings for the daylight module 10 and comprising transparent windows corresponding to the light strips of the style signaling module 12.
  • FIG 2 illustrates in perspective the mask 14 of the projector of the figure 1 .
  • the mask 14 includes openings 14.1, 14.2 and 14.3 for the daytime running light module 10 ( figure 1 ). It also includes elongated windows, in this case three transparent windows 14.4 intended to form the light bands of the style signaling module 12.
  • the mask 14 is advantageously made of transparent or translucent material covered, on the exterior face, with a layer of opacifying paint 14.5 with the exception of windows 14.4. More particularly, the mask 14 is advantageously a single piece made by injection of plastic material into a mold.
  • FIGS. 3 and 4 are two perspective views of an optical guide 16 of the style signaling module 12 ( figure 1 ) arranged behind and under the mask 14 ( figures 1 and 2 ).
  • Figure 3 is a front view of the optical guide 16 oriented essentially according to its mounting position in the projector as illustrated in figure 1 while figure 4 is a rear view.
  • the optical guide 16 is made of transparent or translucent material, advantageously in one piece, produced by injection of plastic material into a mold.
  • the optical guide 16 is generally extended and essentially comprises a guide portion 18.1 and 18.2, tubular and rounded, and a sheet 20 adjacent and connected to the guide portion 18.1 and 18.2. More particularly, the optical guide 16 comprises two guide portions 18.1. and 18.2 arranged one in the extension of the other, along the rear edge of the sheet 20. Each of the guide portions 18.1 and 18.2 is supplied at one end, at the level of an entry face, by a specific light source. It is understood that the number of guide portions can vary and depend in particular on the length of the sheet to be supplied with light and also on the space available to accommodate light sources. The light gradually leaves the guide via a rib connecting the guide portion to the sheet. The tablecloth is thus supplied with light all along its rear edge.
  • the guiding portion(s) are generally tubular with a cross section having a rounded profile such as a circle or an oval, so as to be able to guide the light by successive reflections on the diopter formed by the exterior surface in contact with the air ambient.
  • THE figures 5 and 6 are rear detail views of the central part of the optical guide of the figures 3 and 4 .
  • Each of the guide portions 18.1 and 18.2 is connected to the sheet 20 by a rib 22.1 and 22.2 respectively. It can be observed that these ribs 22.1 and 22.2 form grooves on the upper and lower faces of the optical guide 16, essentially due to the thickness and the inclination of the ribs in question.
  • Each portion of guidance 18.1 and 18.2 has at one of its ends a light entry face. To the Figure 6 , the entry face 18.2.1 of the second guide portion 18.2 is visible. Fixing means, such as positioning pins, are visible near the entry face 18.2.1 of the second guide portion. Similar means are also provided at the other ends of the guide portions 18.1 and 18.2, namely near the entry face of the first guide portion 18.1 (on the left on the figure 4 ) and at the end of the second guide portion 18.2 (on the right on the Figure 4 ).
  • FIGS. 7 and 8 are two sectional views of the central part of the optical guide, illustrated in figures 5 and 6 .
  • the rib 22.2 connecting the sheet 20 to the guide portion 18.2 and the grooves that said rib forms at the level of the upper and lower faces of the optical guide 16.
  • the rib 22.2. has an evolving shape so as to gradually promote the exit of light from the guide portion 18.2 towards the sheet 20, as one moves away from the light source, so as to compensate for the progressive loss of light .
  • the sectional view at Figure 7 is close to the entrance face 18.2.1 visible at the Figure 6 .
  • the quantity of light transmitted by the guide portion 18.2 is therefore still significant.
  • the rib 22.2 has a shape that is not very favorable to the transmission of light towards the sheet 20, while further downstream along the main direction of the guide portion 18.2, the shape of the rib 22.2 gradually evolves in a manner to promote the transmission of light towards the sheet in order to ensure homogeneous distribution of light all along the guide portion.
  • the direction in which the shape of the rib changes namely by decreasing or increasing the fraction of light traveling through the guide portion which has exited said portion, along the guide portion may be different, depending on in particular the location of the light source(s) and the light requirements.
  • the thickness of the rib makes it possible to influence in a fairly direct manner the quantity of light transmitted to the sheet.
  • the rib 22.2 has a limited thickness near the light entry face and progressively more important downstream along the guide portion 18.2.
  • Other shape parameters of the rib are also likely to influence the quantity of light transmitted to the sheet, such as in particular the inclination of the rib relative to a direction passing through the center of the guide portion and the zone of junction of the rib.
  • FIG 8 illustrates the correspondence between the optical guide 16 and the mask 14, more particularly at the level of the windows 14.4 forming the light bands.
  • the sheet 20 includes means for letting out through the upper face the light passing through the sheet by successive reflections along its extent. These means may include graining on the exit face and are detailed below in relation to the Figure 10 .
  • FIG. 9 essentially corresponds to the configuration of the Figure 7 .
  • the rib 22.1, 22.2 extends in a main direction 24.1, 24.2 with an average thickness e, and forms an angle ⁇ with a radial direction passing the zone of adjacency of the rib to the guide portion 18.1, 18.2.
  • a low thickness e reduces the fraction of light leaving the guide portion, per unit length of said guide, and vice versa.
  • a low angle ⁇ increases the fraction of light leaving the guide portion, per unit length of said guide, and vice versa.
  • the rays of light which propagate along the guide portion 18.1 and 18.2 are likely to exit the guide and undergo reflection in the rib at a distance from said portion or in the sheet mainly when the rib is aligned with the ray passing through the zone of adjacency of the rib to the guide portion, in other words when the angle ⁇ is zero.
  • this angle is large, a portion of rays reflecting on the area of the rib adjacent to the guide portion will remain in said portion. Another part of the rays will be reflected multiple times in this area and then in the rest of the rib before reaching the sheet. This means that the re-entry of these outgoing rays into the water table takes place further downstream. It is also clear that the thicker the rib, the greater the number of rays which exit from the guide portion towards the sheet.
  • the thickness e of the rib 22.1 and 22.2 can have a minimum value of 0.3mm and have a variation of more than 1mm, preferably more than 1.5mm.
  • the maximum value of the thickness e of the rib is less than the average diameter of the guide portion, preferably less than 70% of said diameter.
  • FIG. 10 illustrates a shape of the rib 22.1, 22.2 more favorable to the exit of light towards the sheet, due to the greater thickness e and the lower angle ⁇ , in comparison with the configuration of the Figure 9 .
  • FIG 11 is a representation of the optical guide 16, such as in Figure 3 but however showing the light output means from the upper face of the sheet 20.
  • These means consist of a graining 20.2 of certain zones of the upper face, while the rest of said face 20.1 remains smooth.
  • the graining advantageously has a grain size greater than 20 ⁇ m and/or less than 40 ⁇ m. This graining is advantageously carried out during the molding of the optical guide 16, by graining the affected areas of the mold. Such graining of the mold can be carried out by applying a laser beam.
  • optical guide, the style signaling module and the projector which have just been described are advantageous in that they make it possible to carry out a signaling function of potentially complex shape while ensuring good homogeneity of light intensity, especially from different points of view in front of the projector, in an economical manner.
