Definitions

  • the invention relates to lighting devices, and more precisely those which comprise at least one light source associated with a mask in order to provide at least one predefined photometric function.
  • the term “lighting device” is understood to mean a light device capable of ensuring at least one photometric function of lighting or signaling or of light effect, possibly decorative.
  • lighting devices are used, such as those defined above, to provide at least one predefined photometric function, such as for example a position light function (or night light or lantern) or a daytime running light function (or DRL (for "Daytime running Light (or Lamp)" - light signaling automatically switched on when the vehicle is put into operation during the day)).
  • a position light function or night light or lantern
  • a daytime running light function or DRL (for "Daytime running Light (or Lamp)" - light signaling automatically switched on when the vehicle is put into operation during the day)
  • the mask is a part, generally made of plastic material, and responsible for preventing the passage of the photons generated except at predefined places.
  • the mask comprises opaque zones, which possibly appear when they are backlit, and one or more transparent zones allowing the photons to pass.
  • the mask comprises patterns on its front face which appear when they are backlit by the rear face and which are almost invisible in the absence of backlighting. These patterns are generally defined by metallization then laser ablation, or by partial metallization by means of a metallization resist mask, or by screen printing on a bonded or overmolded film, or even by printing.
  • This type of mask which is described in particular in the patent document EN 3011312 , generally allows to define only patterns two-dimensional (or 2D), with no real relief (or 3D) effect, and intended exclusively to produce a luminous style effect, sometimes decorative. Consequently, these patterns do not generally take part in a predefined photometric function of the lighting device of which they form part, which means that it is necessary to add to the latter or to neighboring equipment optical elements allowing the outgoing photons to satisfy the conditions which define this predefined photometric function.
  • the optical elements are generally defined on one face of a protective glass placed at the interface with the exterior. These optical elements, which are for example lenses, facets, beading, or streaks, are visible and therefore can be detrimental to a desired style effect, or even be considered as defects.
  • the object of the invention is therefore in particular to improve the situation.
  • 3D patterns are available which not only participate in a luminous effect, possibly decorative, but also actively contribute, together, to the predefined photometric function, which makes it possible to avoid to have to add additional optical elements to their lighting device or to neighboring equipment.
  • the invention also proposes a vehicle optical unit, optionally of the automotive type, and comprising at least one lighting device of the type presented above.
  • the invention also proposes a vehicle, optionally of the automobile type, and comprising at least one lighting device of the type of that presented above and/or at least one optical unit of the type of that presented above.
  • the object of the invention is in particular to propose a lighting device DE with light source(s) SL and mask M, and capable of ensuring at least one predefined photometric function.
  • the lighting device DE is intended to equip an optical unit BO of a vehicle of the automobile type, such as for example a car.
  • a lighting device DE can be an item of equipment in itself (possibly comprising its own housing), or else can be part of equipment other than a vehicle headlight unit.
  • a DE lighting device can be part of any vehicle (land, sea (or river), or air), any installation, including industrial type, any device ( or system), and of any building.
  • the optical unit BO (comprising at least one lighting device DE) is a rear light providing at least one photometric signaling function, such as for example a position light function (or pilot light or lantern).
  • the lighting device DE is a lighting device capable of providing at least one photometric lighting or signaling function or a lighting effect, possibly decorative.
  • it could, for example, provide a daytime running light function (or DRL (for "Daytime running Light (or Lamp)" - light signaling automatically switched on when the vehicle is put into operation during the day)).
  • the X direction is a so-called longitudinal direction because it is parallel to a longitudinal side of a vehicle
  • the Y direction is a so-called transverse direction because it is perpendicular to the longitudinal sides of this vehicle and therefore perpendicular to the longitudinal direction X
  • the direction Z is a vertical direction, perpendicular to the longitudinal X and transverse Y directions.
  • a vehicle optical unit BO here a rear light
  • a housing BB delimiting part of a cavity housing a lighting device DE according to the invention, as well as any other lighting means providing at least one other photometric function
  • a protective glass GP made of glass or plastic.
  • the BB box is intended, here, to be secured to a part of the body of a vehicle (here in a rear part). It is made of a rigid material, such as for example a plastic or synthetic material. In this case, it can be made by molding.
  • a lighting device DE comprises at least one light source SL and a mask M.
  • Each light source SL is capable of generating photons intended for the mask M, directly or indirectly.
  • each The light source SL can be a light-emitting diode, of the conventional type (or LED (“Light-Emitting Diode”)) or of the organic type (or OLED (“Organic Light-Emitting Diode”)), or else a laser diode.
  • each light source SL can, for example, be installed on a support plate PS.
  • This support plate PS can, for example, be a printed circuit board, of the PCB (“Printed Circuit Board”) type, rigid or flexible (“of the “Flex” type).
  • the mask M is specific to (or arranged to) allow the photons which are generated by the light source(s) SL to pass at predefined locations.
  • it can be made by molding in a plastic material such as polycarbonate (or PC) or polymethyl methacrylate (or PMMA), or glass.
  • the color of the material in which the mask M is made depends on the predefined photometric function in which it participates and/or on the wavelength of the photons generated by the light source(s) SL. For example, its color can be red or orange, or white crystal, depending on the needs.
  • the mask M can have a non-zero average inclination with respect to a horizontal plane XY. For example, it (M) can be inclined with respect to this horizontal plane XY by an angle comprised between 20° and 50°.
  • This mask M comprises a front face FV, facing outwards (and therefore towards the protective glass GP), and a rear face FR, opposite to the front face FV and receiving the photons generated by the source(s). ) of light SL.
  • the lighting device DE can also comprise a reflector RP capable of reflecting the photons, generated by the light source(s) SL, towards the rear face FR of the mask M.
  • the photons generated by the light source(s) SL initially move towards the reflector RF which reflects them towards the rear face FR of the mask M.
  • the lighting device DE could not include a reflector RP, and in this case the photons generated by the light source(s) SL are directed directly towards the rear face FR of the mask M.
  • the front face FV of the mask M is provided with three-dimensional elements ET which together participate in a predefined photometric function of the lighting device DE and each have a general diamond-point shape defined by at least two opaque facets FOj and at least two transparent facets FTj.
  • general diamond-point shape is understood here to mean a 3D polyhedron with planar polygonal faces (or facets) arranged with respect to each other in a manner similar to a diamond.
  • the opaque facets FOj of each three-dimensional element ET are contiguous and inclined relative to each other.
  • the transparent facets FTj of each three-dimensional element ET are contiguous and each extend in an inclined manner, in one of the predefined places (through which the received photons pass), one of the opaque facets FOj in the direction of a facet opaque FOj of at least one other neighboring three-dimensional AND element.
  • a three-dimensional element ET can comprise any number of opaque facets FOj and therefore of transparent facets FTj, provided that this number is at least equal to two.
  • each three-dimensional element ET constitutes a 3D pattern in the shape of a diamond point which appears when it is backlit by the rear face FR, and whose relief is highlighted (even amplified) by the photons which come out from each of its transparent facets FTj which extend its opaque facets FOj in the direction of at least one other neighboring three-dimensional element AND. Consequently, the three-dimensional elements ET not only participate, together, in a luminous effect, possibly decorative, but also actively contribute, together, to the predefined photometric function of their lighting device DE.
  • the three-dimensional elements ET are preferably placed relative to each other (here in an optical unit BO) so that their transparent facets FTj together deliver photons in a predefined horizontal angular sector and in a predefined vertical angular sector SAV.
  • horizontal angular sector here means an angular sector comprised in a horizontal plane XY.
  • vertical angular sector SAV here means an angular sector comprised in a vertical plane XZ.
  • the horizontal angular sector and the vertical angular sector SAV are predefined in order to satisfy the conditions which define the predefined photometric function which is ensured by the lighting device DE (via the mask M).
  • the predefined horizontal angular sector can be defined as a function of an internal viewing angle SS1 of an observer with respect to an axis AX having a predefined direction and of an external viewing angle SS2 of this same observer with respect to this same axis AX.
  • This internal observation angle SS1 corresponds to the maximum internal angular separation of the observer with respect to the axis AX where he still perceives the light emerging from an optical block BO according to a predefined intensity.
  • the external observation angle SS2 corresponds to the maximum external angular separation of the observer with respect to the axis AX where he still perceives the light emerging from this same optical block BO according to a predefined intensity.
  • the angles SS1 and SS2 relate to the optical block BO on the left.
  • the axis AX is the axis which is parallel to the direction longitudinal X of the vehicle and which passes through the median longitudinal plane XZ of the latter. This axis AX therefore passes halfway between the left and right rear optical units (see figure 4 ).
  • the internal observation angle SS1 can be between 30° and 60°.
  • the external viewing angle SS2 can be between 70° and 90°.
  • the internal observation angle SS1 can be equal to 45° and the external observation angle SS2 can be equal to 80°.
  • the predefined vertical angular sector SAV can be subdivided into an upper sub-sector SS3 and a lower sub-sector SS4, on the one hand, extending mutually on either side of the axis AX (having a predefined direction) , and, on the other hand, having respectively first and second predefined vertical angular extensions.
  • This upper sub-sector SS3 corresponds to the maximum upper angular separation of the observer with respect to the axis AX where he still perceives the light coming out of an optical block BO according to a predefined intensity (see figure 5 ).
  • the lower sub-sector SS4 corresponds to the maximum lower angular separation of the observer with respect to the axis AX where he still perceives the light coming out of this same optical block BO according to a predefined intensity (see figure 5 ).
  • the first predefined vertical angular extension (of the upper sub-sector SS3 of the vertical angular sector SAV of the lighting device DE of an optical block BO) can be between 5° and 25°, upwards.
  • the second predefined vertical angular extension (of the lower sub-sector SS4 of the vertical angular sector SAV of the lighting device DE of an optical block BO) can be between 5° and 25°, downwards.
  • the first predefined vertical angular extension may be equal to 15° upwards and the second predefined vertical angular extension may be equal to 15° downwards.
  • each three-dimensional element ET can be inclined relative to each other by an angle ⁇ which is between 105° and 125°.
  • angle ⁇ can be equal to 114°.
  • At least the opaque facets FOj can be polished on the side of the front face FV, and that at least areas of the rear face FR of the mask M, located behind the transparent facets FTj, can also be polished. These polishings are intended to "burst” or “distribute” the photons along many directions in order to facilitate obtaining the vertical angular sector SAV associated with the photometric function, in particular when the latter is a position light function (or lantern) .
  • the transparent facets FTj of the three-dimensional elements ET can mutually extend along lines (here oblique) which intersect and where the photons define light bands which intersect.
  • a kind of frame or luminous grid is thus obtained via the transparent facets FTj.
  • each opaque facet FOj can, for example, be coated on the front face FV with a metal layer which is suitable for ensuring its opacity.
  • this metallic layer can be aluminum or nickel/chromium.
  • each transparent facet FTj can, for example, present a transparency which results from an ablation, by means of a laser, of the metal layer previously deposited on the entire front face FV, or else from depositing a resist (or a resist mask) during the metallization phase.
  • a resist or a resist mask
  • each transparent facet FTj of a three-dimensional element ET can, for example, have a general (quasi) triangular shape. This general shape here gives the impression that the opaque facets FOj are “open” in their lower part extended by the two associated transparent facets FTj. But the transparent facets FTj of the three-dimensional elements ET can have other general planar polygonal shapes. Moreover, the transparent facets FTj are not necessarily identical from one three-dimensional element ET to another.
  • the three-dimensional elements ET placed on the same line at a given level have substantially identical transparent facets FTj, but of different dimensions from those of the transparent facets FTj of the three-dimensional elements ET which are placed on the same line at a higher or lower level.
  • the height of the short side of each transparent facet FTj can increase when the level decreases, in order to reinforce the opening effect of the opaque facets FOj located in the lower levels.
  • the angle existing between an opaque facet FOj and an associated transparent facet FTj may possibly vary, for example according to the level to which the three-dimensional element ET belongs. This is particularly the case in the example of mask M illustrated in the figure 1 . But this angle could be substantially constant.
  • the angle mentioned in the previous paragraph can be a function of the general angle of inclination of the mask M with respect to the horizontal plane XY and/or of the shape of a sub-part of the possible reflector RP which is intended to reflect the photons towards associated three-dimensional elements ET (and therefore in particular towards their transparent facets FTj and opaque facets FOj).
  • the lighting device DE when it is a light tail providing a position light function, it must produce a red light.
  • the red color may result, for example, from the use of light source(s) SL generating photons whose wavelength is that of white and from a mask M having this red color (possibly crystal).
  • This last combination makes it possible to have an off rendering of red color on the transparent facets FTj.
  • an RP reflector comprising, as indicated above, predefined sub-parts in order to reflect the photons respectively towards associated three-dimensional AND elements (placed at different levels), makes it possible to have a rendering homogeneous at the level of the opaque facets FOj while respecting the photometric constraints thanks to the exit of the photons by the transparent facets FTj.
