Definitions

  • the present invention relates to a device for lighting and / or signaling metallized ice, in particular a lighting and / or signaling device for a motor vehicle. It relates to the field of headlamps and motor vehicle lights, in which there are different types of lighting, among which the position lights, the change of direction (flashing) lights, the dipped beam or codes, the lights of road, "long-range" complement lights, fog lights, daytime running lights, etc.
  • Headlamps and lights increasingly include a smooth, totally translucent exterior mirror that allows the reflector to be seen in perfect transparency. This trend has the effect of generalizing the metallization of the interior of the headlamps and lights.
  • Metallization means a surface treatment which gives a glossy reflectivity to an opaque material, by depositing a thin layer of a material such as aluminum. This process is commonly applied for the construction of headlamp masks. In the present case, it is proposed to apply a metallization process to a translucent material, such as glass or PMMA (polymethyl methacrylate), PC (polycarbonate), a thermoplastic such as APEC. By applying it on the inside of an outer ice of the lighting and / or signaling device, it limits the transparency to the thickness of the material, retaining in particular its color, and making its inner surface reflective.
  • a translucent material such as glass or PMMA (polymethyl methacrylate), PC (polycarbonate), a thermoplastic such as APEC.
  • the metallization of the parts poses a problem of aspect: the lines of gluing material, flow material and the sinkings generated by the variations of thickness induced by the fastenings and indexings of the case are as many causes of deformation of the metallized surface.
  • shrinkage is meant a deformation of the surface condition of a material, due to the contraction of the metal as it cools, as can be observed at the end of solidification.
  • a first solution is to use an additional piece, the mask, which comes between the housing of the lighting and / or signaling device and the outer ice and on which it will be more easily removed the sinkings having only small bindings and indexing to integrate. But the metallization of the mask causes the reflection of light in certain areas causing parasitic light rays.
  • a second solution is to apply style shapes, such as gadroons, streaks, graining, which hide the appearance defects.
  • a lighting and / or signaling device for a motor vehicle comprising a mask constituting the periphery of the side walls of two cavities intended to house, in each of them, at least one lamp .
  • the mask comprises at least two parts mechanically fixed to one another, removably, at least one being extended by a reflector or a reflector portion.
  • This is mainly in this device a type of mask that incorporates several features to reflectors, such as that to add a type of "occulteur” style, a cover to prevent the arrival of the light beam on the mask or a Fresnel lens to change the appearance of the light beam.
  • the object of the present invention is to design a new lighting and / or signaling system with metallized ice, in which the aforementioned drawbacks are eliminated thanks to a new, simpler, reliable and economical technical solution.
  • the object of the present invention is to design a new technical solution, which is different as a result of the solutions adopted in the lighting and / or signaling devices of the prior art, which makes it possible in particular to eliminate the problems of aspect mentioned above and the problems related to parasitic light rays.
  • the invention proposes a new lighting and / or signaling device for vehicle. It comprises a housing with at least one cavity comprising at least one lamp and at least one reflector, and an outer mirror, mounted on the housing, a part of which is coated on its inner face with a metallization layer, said metallized portion of the outer ice being the part that is not located in front of the lamps, to let through the light necessary for lighting and / or signaling functions.
  • the part of the outer ice coated on its inner face with a metallization layer is the part located near the junction with the housing, in order to hide the appearance defects of the housing.
  • the portion of the outer ice coated on its inner face with a metallization layer is interrupted on at least one zone of the outer ice, in order to reinforce the visual signature of the lighting and / or signaling lights.
  • said at least one area is a narrow band-shaped area.
  • said narrow band-shaped zone is located at the periphery of the outer ice, so as to emphasize the outline of the lighting device.
  • said at least one region of interruption of the metallization layer has a shape having a specific design used to identify the vehicle.
  • FIG. 1 there is shown schematically an automotive projector according to a technical solution of the prior art.
  • the projector is of conventional construction with an outer glass 1, one or more lamps such as the lamp 3, a reflector 2 with a substantially parabolic inner surface metallized so as to reflect the light rays emitted by the source 3, a mask 4 of shape and the housing 6.
  • the lens 1 is mounted on the housing 6, via the peripheral mounting rib 6a.
  • the mask 4 is mounted between the housing 6 and the ice 1, in the space around the light sources and their reflectors, and it is therefore widely open in its central part to let the light emitted by the lamp 3 to the outer ice 1 transparent.
  • the mask 4 is molded in one piece and, like the reflectors, undergoes a metallization type surface treatment step.
  • This metallization step is delicate, insofar as it requires a homogeneous coating appearance, very continuous. The larger the pieces to be metallized, the more this homogeneity of appearance is difficult to obtain. The simultaneous metallization of the masks and the associated reflectors is difficult, when the cavities thus created are much deeper than high.
  • each of which is equipped with one or more lamps to perform several functions.
  • These cavities comprise reflector walls. These walls have a bottom pierced with an opening to allow to introduce and possibly fix the lamp in the cavities.
  • FIG. 2 there is shown schematically an exemplary automotive headlight according to the present invention.
  • a mask 4 In the construction of FIG. 2, there is no longer a mask 4, and a part of the inner face of the outer ice 1 is coated with a metallization layer, of thickness designated "e", namely the internal face portions 7a and 7b of the outer ice 1.
  • the metallized portions 7a and 7b of the inner face of the outer glass 1 are chosen so as not to be in front of the lamps and functions in order to pass the light necessary for the lighting and / or signaling functions.
  • the sector referenced A in the drawing of FIG. 2 represents the space in which the light emitted by the light source 3 passes.
  • the application of a metallization on the inner face of the outer glass 1 has the advantage of masking the appearance defects of the housing 6, saving an additional piece such as the mask 4 of the embodiment of the invention.
  • prior art illustrated in Figure 1. The metallized areas 7a and 7b of the ice 1 are located in the region near the junction 6a of the ice 1 with the housing 6, and this situation offers the advantage of masking the appearance defects of the housing in this part.
  • the outer ice 1 is metallized on its inner face leaving a zone A without metallization to allow the passage of the luminous flux from the light source 3.
  • This luminous flux which passes through the transparent wall of the outer ice 1 is illustrated by all the light rays designated "a".
  • the metallization, of thickness "e” carries, as in the previous example of FIG. parts 7a and 7b of the outer ice 1, located on either side of the portion A. But in the embodiment of FIG. 3, the metallization does not extend to the ends of the outer ice 1 at adjacent the link 6a with the housing 6.
  • the metallization is "interrupted" on the periphery of the glass 1, said metallization interruptions being referenced 7c and 7d, of transverse length h 1 and h 2 , respectively.
  • the radius designated c represents the portion of light, emitted by the lamp 3, which is reflected by the metallized inner surface 7a of the glass 1, and then directed by this reflection against an inner wall of the housing 6 before crossing the outer ice 1 in its non-metallized portion 7c in the form of a narrow strip of length h 1 in cross section.
  • the designated ray d in the drawing of FIG. 3 illustrates the portion of light emitted by the light source 3 which is directed directly on the non-metallized portion 7d at the periphery of the outer ice 1.
  • the non-metallized zones 7c and 7d make it possible to create a specific luminous shape identifying the vehicle either by a specific drawing or by emphasizing the specific contour of this fire which is that of the smooth and translucent ice 1.
  • such a luminous shape creation by drawing one or more metallization interrupts can also be applied on a screen located between the housing 6 and the outer mirror 1, so as to create perspective effects.
