Definitions

  • the present invention relates to a signaling light, in particular for a motor vehicle, capable of emitting light radiation of colored signaling, of the type comprising a colorless closing lens, a reflection means such as a reflector, a filament lamp, a means for coloring the light radiation coming from the filament and means for at least partially masking said coloring means so as to give the extinguished signaling light an essentially colorless external appearance.
  • the coloring of the light is given by the glass or the globe for closing the light, which is appropriately tinted.
  • the amber or orange-yellow color used for the front indicators of motor vehicles is very poorly combined with the appearance of neighboring headlights and the overall appearance of the vehicle is thus degraded.
  • the current trend is to give all the exterior surfaces of the lighting devices of a vehicle, whether at the front or at the rear of the vehicle, a relatively uniform color and appearance, especially at the front of the vehicle.
  • Such a light includes a lamp, emitting white light, a reflector and a colorless closing glass.
  • This light further comprises a balloon forming a colored filter, for example of amber color for a flashing light, which is interposed between the lamp and the reflector.
  • This balloon has on its outer face a cover, for example reflective, which is provided in certain areas (bands ...) of the balloon and which contributes to attenuating the amber aspect of the fire when the lamp is off and it is observed from the outside.
  • the balloon is relatively large, because it must leave a space around the lamp large enough to avoid excessive heating inside of it.
  • the cover should not cover an excessive portion of the surface of the balloon, as it influences the light output which cannot be excessively reduced. For these reasons, the amber color of the extinguished fire as observed from the outside is certainly attenuated, but it remains however perceptible.
  • the present invention provides a signaling light of the type mentioned in the introduction characterized in that said coloring means is constituted by a colored bulb of the lamp and in that said masking means is constituted by an opaque cover of neutral or reflecting aspect covering a frontal region of the colored bulb of the lamp.
  • frontal region of the colored bulb of the lamp is understood here to mean the region of said bulb facing the closing glass.
  • neutral appearance means a color, possibly metallized, which when the fire is out and exposed to external radiation has a color and a brightness similar to those of the neighboring parts of the fire, in particular of its means of reflection. .
  • the only colored part of it is constituted by the lateral parts of the colored bulb of the lamp.
  • These lateral parts are small parts and located laterally with respect to the optical axis of the light.
  • the cover being of reduced dimensions, it is located more discreetly inside the light.
  • the cover consists of a hollow body of which a concave face, facing the lamp, is reflective.
  • the cover thus also forms a recuperator of the flux emitted forward by the filament, to return it to the reflection means.
  • the opaque cover of neutral appearance is constituted by an aluminized coating formed on the front region of the bulb.
  • said opaque cover is a neutral metallic paint applied to the front region of the bulb.
  • This paint can advantageously be gray in color or the like.
  • the opaque cover is a screen which is applied tightly to the front region of said colored bulb of the lamp and is fixed by fixing means for example on the reflector.
  • This screen is made of a metal or any material that can withstand the temperature generated by the lamp. It is painted or provided with a reflective coating on its outer face.
  • This signaling light capable of emitting a colored signaling light radiation, comprises a reflection means 20, a filament lamp 30 and a colorless closing glass 10 closing the light at the front.
  • the reflection means can consist of any optical device capable of returning at least part of the radiation emitted by the filament towards the rear 10.
  • it is a reflector of the parabolic type, defining a focal point F in the vicinity of the filament and an optical axis X - X '.
  • the filament lamp 30 advantageously comprises a colored bulb 31 giving the colored light radiation of the signaling light.
  • the color of the bulb is amber.
  • this colored bulb 31 includes an opaque cover 41 with a neutral or reflective appearance covering at least partially the front region of the colored bulb of the lamp, located opposite the colorless closing glass 10.
  • this cover is essentially hemispherical and preferably comprises on its convex outer surface, either a reflective aluminized coating, or a neutral metallic paint, for example of gray, mat or glossy color.
  • the colored bulb colors the light rays emitted by the filament, these being reflected on the wall of the reflector in a direction close to the optical axis X - X 'and through the glass of colorless closure 10.
  • the signaling light of FIG. 1 is extinguished, it has an essentially colorless external appearance, because the opaque cover covering the front region of the bulb at least partially masks the colored parts of it for a fairly wide range of viewing angles.
  • the light rays coming from the outside and meeting the outside surface of the cover are reflected, scattered or partly absorbed, the reflected or scattered rays keeping the same color.
  • FIGS. 2 and 3 a variant of the embodiment of the signaling light in FIG. 1 is shown.
  • This signaling light comprises an opaque cover constituted by a screen 42 of neutral or else reflecting aspect applying to the front region of the colored bulb 31 of the lamp 30, colorless closure 10.
  • This screen 42 is a piece of metal or else made of material resistant to the heat emitted by the lamp in illumination. This screen can be produced by molding, stamping or forging, depending on the type of material used.
  • the screen 42 can advantageously be coated on its convex outer face with a reflective aluminized layer or else with a neutral, matt or metallized paint, or even with a protective layer of zinc.
  • the concave inner face of the screen 42 is reflective, for example aluminized, the screen thus constituting a means of recovering the luminous flux emitted by the filament towards the front, to return it in the direction of the reflecting means. so that it participates in the beam formed, the light output is thus preserved.
  • the screen can be hemispherical and centered in the vicinity of the filament.
  • this screen 42 comprises thin fixing lugs 43, 44 placed respectively in two diametrically opposite regions, for example above and below the lamp 30, and coming to be fixed on the reflector 20 in the vicinity of the hole of lamp.
  • fixing notches 43 ', 44' are provided on the reflector 20 to receive the fixing tabs 43, 44 of the opaque screen 42.
  • this opaque screen has the same functions as the aluminized coating or the neutral paint of FIG. 1 and also has the advantage of not requiring any special treatment on the lamp, which can be an ordinary lamp with colored bulb.
  • the fixing lugs 43,44 are sufficiently narrow to at least obscure the radiation from the filament.
  • the opaque recuperator screen essentially covers the same area of the bulb as the aluminized coating or the paint of FIG. 1.
  • FIGS. 4 and 5 a variant of the embodiment of the signaling light in FIG. 2 has been shown.
  • the opaque cover is a screen 42 of neutral or reflective appearance which is fixed to a lateral part of the reflector 20, by means of a wall 45 extending from one side of said screen 42, towards the rear and essentially parallel to the optical axis.
  • This side wall 45 also makes it possible to dissipate the heat accumulated in the screen under the effect of the radiation from the lamp.
  • This embodiment is advantageously used in traffic lights of small width and reduced volume.
  • a light produced according to the present invention may be a front flashing light with colorless appearance located in the vicinity of a headlamp with transparent glass, or a rear signaling light (flashing, position light, brake light, ...) placed for example in the vicinity of a reversing light, or in a symmetrical position of a reversing light provided on the opposite side of the vehicle.
  • the cover can be designed on its concave inner face to absorb at least partly the radiation from the filament.
