Definitions

  • the present invention relates generally to lighting or lighting devices. signaling, intended to equip motor vehicles.
  • Such devices usually include a housing serving as support and positioning different optical components, such as one or more light sources, one or more reflecting surfaces collecting the light flux emitted by these sources to redirect it to a window for closing and protecting the lighting device or signaling.
  • a housing serving as support and positioning different optical components, such as one or more light sources, one or more reflecting surfaces collecting the light flux emitted by these sources to redirect it to a window for closing and protecting the lighting device or signaling.
  • Light sources used in signaling devices can fill several functions: they can for example constitute a lantern, a stop light, an indicator change of direction, rear fog light, etc., many of these functions can be grouped in the same case closed by a single glass. Likewise, light sources used in lighting devices can fulfill several functions : to form beams of crossing, road, fog light, and also functions of signaling such as a city lamp or a direction change indicator.
  • the glass of a lighting and / or signaling device can spread to regions where it no longer has any optical function, but only one aesthetic or aerodynamic role, for the sake of continuity of shapes or lines with the bodywork surrounding the vehicle. It is then common to have in these regions, behind the protective glass, a so-called “style” mask, provided with an adequate coating, for example reflective or, in the absence of a mask, to conform or to treat the casing of the device lighting or signaling, then visible behind the protective glass, so that it has a predetermined appearance, most of the time glossy, obtained by aluminizing the mask visible through protective glass.
  • a so-called “style” mask provided with an adequate coating, for example reflective or, in the absence of a mask, to conform or to treat the casing of the device lighting or signaling, then visible behind the protective glass, so that it has a predetermined appearance, most of the time glossy, obtained by aluminizing the mask visible through protective glass.
  • the general tendency is to use a mask or a case, on which a layer reflective was deposited by aluminizing, in front of which is placed a closing glass colored or not. If the lighting or signaling device has several compartments each fulfilling a lighting or signaling function, having by definition different regulatory colors, it follows that the glass cannot have the same color in front of these different compartments.
  • one solution is to use a lightly colored glass, and to place between the light source of each compartment and the glass a colored filter, of appropriate color compared to that of ice to obtain by subtractive synthesis a signaling beam of color regulatory.
  • the present invention is placed in this context and aims to provide a device lighting or signaling whose parts do not participate in the development of the beam luminous lighting or signaling and visible through the closing glass have a predetermined appearance and / or color without having the drawbacks of the prior art, that is, by increasing neither the time nor the manufacturing cost nor the rejects, so simple and without disturbing the light or signaling light beam.
  • the present invention therefore relates to a lighting or signaling device for a motor vehicle, comprising a housing forming a support for at least one source light associated with at least one reflecting surface to form a light beam or signaling, a closing window being disposed in front of the light source, a mask being placed between the case and the closing glass in neutral zones of the device lighting or signaling.
  • the reflecting surface intended to form a beam lighting or signaling is metallized or metallic, and the mask is made of material transparent.
  • a signaling device designated as a whole by reference 10, and intended to be installed in a housing 12 formed in the body 14 of a vehicle.
  • a signaling device comprises a housing 16, fixed to the vehicle by means not shown, and serving as a support for different optical components, such as one or more light sources 18, one or more reflective surfaces 20 collecting the light flux emitted by the sources 18 to redirect it to a lens 22 of closure and protection of the signaling device 10.
  • the closing glass 22 ensures the continuity of shapes and lines with the adjacent bodywork elements 14 of the vehicle. It follows that regions of ice 22, such as A in FIG. 1, have no optical function, and do not are crossed by none of the light rays emitted by the source 18. Such regions A are called in this description the "neutral zones" of the lighting or signaling device. An outside observer can then see through the glass 22 the case 16, whereas in other regions the usual optical elements such as the light source 18 and the reflecting surface 20 are visible.
  • the reflecting surface 20 is obtained by metallization of the part of the housing 16 located in the vicinity of the lamp 18, and whose shape is determined, for example by molding, to give the light beam reflected by the surface 20 predetermined properties.
  • the reflecting surface 20 is a metal surface supported by the housing 16.
  • the mask 24 in transparent material, by example of polymethylmethacrylate (PMMA) or polycarbonate (PC), so that it leaves thus appear the housing 16, generally made of plastic material such as polypropylene (PP), polycarbonate (PC) or acrylonitrile butadiene styrene (ABS).
  • PMMA polymethylmethacrylate
  • PC polycarbonate
  • ABS acrylonitrile butadiene styrene
  • FIG. 2 a sectional view of the device signaling of Figure 1, in region A of ice 22.
  • the beam I usually consists of natural daylight, white in color, or artificial light, close to white light.
  • This beam crosses the ice 22, then the transparent mask 24, to reach the housing 16, of opaque material. It is then reflected, by the housing 16, and it again crosses the transparent mask 24, then the glass 22 for emerge from the signaling device where it can be perceived by the eye of an observer.
  • the housing 16 has a surface condition known as "mirror polish", so as to obtain specular reflections from the light rays incident on it.
  • the light beam I 2 after passing through the transparent mask 24, is no longer made up of white light, but contains only wavelengths determined by the color of the transparent mask 24.
  • the beam I 3 reflected and diffused by the wall of the housing 16, in turn contains only wavelengths determined by the color of the transparent mask 24 and by that of the surface of the housing 16 facing the mask 14.
  • the beam I 3 is then fully transmitted by the transparent mask 24, and by the glass 22 to form the emerging beam I 5 .
  • the colored glass 22 does not disturb the photometry of the signaling beam generated by the lamp 18, or may provide to have, between the lamp 18 and the glass 22, a colored filter 26, of a color complementary to that of the glass 22 to obtain, by subtractive synthesis, a light beam of the desired color.
  • the color of the ice 22 can be combined with those of the mask 24 and the housing 16.
  • the light beam I of white light, incident on region A of the glass of the signaling device, is reflected by the colored glass 22 to form the beam I 7 , and it crosses by forming the colored beam I 1 .
  • the beam I 1 is reflected by the mask 24 to form the beam I 6 , which crosses the colored glass 22 to form the beam I 8 .
  • the beam I 1 also passes through the transparent mask 24, to form the beam I 2 , which arrives on the housing 16, made of opaque material. It is then reflected by the housing 16, to form the beam I 3 which again crosses the transparent mask 24 to form the beam I 4 , then the glass 22 to form the beam I 5 emerging from the signaling device where it can be perceived through the eye of an observer.
  • the mask 24 is disposed at a short distance from the housing 16, such so that the mask 24 follows the shapes, concave and convex, of the housing 16, as we have represented in Figure 2.
  • the observer then has the impression of an absence of mask, and that the case itself has received a special surface treatment. For example, for a box of black color, a red mask and a pink ice, the observer the impression that, in neutral areas of the lighting or signaling device, the mask received a Nickel / Chrome metallization followed by a red varnishing.
  • the mask 24 and the housing 16 it will be possible obtain a lighting or signaling device whose parties do not participate in the development of the light or signaling beam visible through the glass of closure have a predetermined color.
  • the present invention is not limited to the embodiments which have have been described, but those skilled in the art may on the contrary make numerous modifications to it that fall within its framework.
  • the present invention applies in the same way to neutral areas of a lighting device, in which the closing glass is so general colorless.
  • the colors of the mask and the case can then be chosen outside color constraints related to signage.
