Definitions

  • the present invention relates to a signaling light, in particular for a motor vehicle, capable of emitting light radiation colored signaling device, of the type comprising a closing lens colorless, a means of reflection such as a reflector, a filament lamp, a means for coloring the light radiation coming from the filament and a means for at least partially masking said coloring means way to give the extinguished traffic light an external appearance essentially colorless.
  • the current trend is to give all of the exterior surfaces of vehicle lighting devices, whether at the front or rear of the vehicle, a color and a relatively appearance uniforms, especially at the front of the vehicle.
  • Such a fire includes a lamp, emitting white light, a reflector and colorless closing glass.
  • This light also includes a colored filter balloon, for example amber in color for a fire flashing, 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 reduce the amber aspect of the fire when the lamp is out and it is observed from the outside.
  • the balloon is of relatively large size, because it must leave enough space around the lamp to avoid excessive heating inside of it. In addition, it should not be the cover covers an excessive portion of the surface of the balloon, because it influences the light output which cannot be excessively reduced. For these reasons, the amber color of the extinguished fire as observed from the exterior is certainly attenuated, but it remains perceptible.
  • the document EP - A - 371 553 describes a lamp type H4 for projector, the bulb of which incorporates a colored translucent interference filter which allows color the beam emitted by the lamp and includes on its front side coating not transparent to spokes luminous.
  • This coating does not perform the function of a means of masking when the fire is out but is designed to intercept the direct light flux emitted by the lamp so that the illumination of said projector meets photometric standards.
  • Such a traffic light which includes a lamellar wall interposed between the colorless glass and the opaque cover, does not take up space negligible, said opaque cover having neither the shape adequate position relative to the bulb of the lamp to form a masking means giving the extinguished fire a colorless appearance.
  • the present invention provides a signaling light according to claim 1 of the this request.
  • frontal region of the colored bulb of the lamp is understood to mean the region of said bulb opposite the closing glass.
  • neutral appearance means a color, possibly metallic, which presents when the fire is out and exposes to a exterior radiation a color and brightness similar to those parts close to the fire, in particular its means of reflection.
  • the only colored part of it is constituted by the lateral parts of the colored bulb of the lamp.
  • These parts lateral are parts of small dimension and located laterally by relation to the optical axis of the fire.
  • the cover being of reduced dimensions, it is located so more discreet inside the fire.
  • the cover consists in a hollow body of which a concave face, turned towards the lamp, is reflective.
  • the cache thus also forms a recuperator of the flow emitted forward by the filament, to return it to the means of reflection.
  • the opaque cover of neutral appearance is consisting of an aluminized coating formed on the front region of the bulb.
  • said cache opaque is a neutral metallic paint applied to the frontal region bulb.
  • This paint can advantageously be gray in color or similar.
  • the opaque cover is a screen which is applied tightly to the frontal region of said colored bulb of the lamp and is fixed by fixing means for example on the reflector.
  • This screen is made up by a metal or any material that can withstand the temperature generated by the lamp. It is painted or provided with a coating reflecting on its outer face.
  • This traffic light likely to emit light signaling radiation, includes a reflection means 20, a filament lamp 30 and a crystal colorless closure 10 closing the light at the front.
  • the reflection means can consist of any optical device able to return at least part of the radiation to the ice 10 emitted by the filament towards the rear. In this case it is a reflector of the parabolic genus, defining a focal point F in the vicinity of the filament and a optical axis X - X '.
  • the filament lamp 30 advantageously comprises a colored bulb 31 giving the colored luminous radiation of the signaling light.
  • the color of the bulb is amber.
  • this colored bulb 31 includes an opaque cover 41 neutral or reflective at least partially covering the frontal region of the colored bulb of the lamp, located opposite the crystal colorless closure 10.
  • this cache is essentially hemispherical and preferably has on its convex outer surface, i.e. a reflective aluminized coating, i.e. a neutral metallic paint, by example of gray, mat or shiny color.
  • the colored bulb When the fire of figure 1 is lit, 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 at through the colorless closing glass 10.
  • the Figure 1 signaling when the Figure 1 signaling is off, it has an external appearance essentially colorless, because the opaque cover covering the frontal region of the bulb at least partially masks the colored parts thereof for a fairly wide range of viewing angles.
  • the light rays coming from outside and meeting the outside surface of the cover are reflected, diffused or part absorbed, the reflected or scattered rays keeping the same color.
  • This signal light includes an opaque cover consisting of a screen 42 of neutral or reflective appearance applying to the region front of the colored bulb 31 of the lamp 30, colorless closure 10.
  • This screen 42 is a piece of metal or of heat-resistant material emitted by the lamp in illumination. This screen can be made by molding, stamping or forging, depending on the type of material used.
  • the screen 42 can advantageously be coated on its face. convex outer surface of a reflective aluminized layer or of a neutral, matt or metallic paint, or a layer of zinc protection.
  • the concave inner face of the screen 42 is reflective, for example aluminized, the screen thus constituting a means of recovery of the luminous flux emitted by the filament towards the front, for send back to the thinking medium 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 includes 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 lamp hole.
  • fixing notches 43 ', 44' are provided on the reflector 20 to receive the fixing lugs 43.44 of the opaque screen 42.
  • this opaque screen has the same functions as the aluminized coating or the neutral paint of figure 1 and presents plus the advantage of not requiring special treatment on the lamp, which can be an ordinary lamp with colored bulb.
  • the fixing lugs 43,44 are narrow enough to at least obscure the radiation from filament.
  • the opaque recuperator screen covers essentially the same area of the bulb as the aluminized coating or the painting in figure 1.
  • the opaque cover is a screen 42 of neutral or reflective appearance which is fixed on 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 axis optical.
  • 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 mode of implementation is advantageously used in traffic lights of narrow width and reduced volume.
  • a fire produced according to the present invention may be a colorless front flashing light located in the vicinity of a transparent window, or a rear signal 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 for the opposite side of the vehicle.
  • the cover can be designed on its face concave interior to at least partially absorb the radiation from the filament.
