Definitions

  • the technical sector of the present invention is that of lighting and / or signaling devices for a motor vehicle, and more particularly the windows fitted to such devices.
  • a projector mounted on a motor vehicle is conventionally composed of a housing closed by an ice thus delimiting an internal volume in which there is a bulb, a reflector and electric cables.
  • the mechanical part of these components is apparent through the ice and it is then necessary to hide this mechanical part.
  • the difference in temperature between the air outside the projector and the air present in the internal volume causes condensation on the ice water in the air because the latter is likely to cool very brutally.
  • the projectors are then provided with a moisture-proof varnish or a system of ventilation of the internal volume of the projector but the effectiveness of these solutions leaves something to be desired.
  • the application of an anti-moisture varnish involves an additional cost and complicates the manufacturing process of such a projector and the ventilation system complicates the development, manufacture and installation of the projector.
  • the object of the present invention is therefore to solve the disadvantages described above mainly by installing on a mirror of a motor vehicle headlight a system whose transparency is electrically controlled.
  • the subject of the invention is therefore a part of a lighting and / or signaling device for a motor vehicle, this part being arranged to be visible from the outside of the device when this part is mounted on this device, characterized in that it comprises a first zone having a variable light transmission coefficient.
  • variable is meant the fact that the first zone can take at least two states in which the perception of the light beam is significantly different.
  • the variability is of the all-or-nothing type, that is to say a first case in which the light beam passes through the first zone without alteration and a second case in which the light beam does not cross the first zone. .
  • the first zone is opaque or reflective.
  • the light beam does not cross the first zone but the invention covers the case where the outer rays are absorbed (opacity) as well as the case where the outer rays are returned or reflected, the latter case avoiding a heating of the room.
  • the variability considered here is activated or deactivated electrically. The piece is visible when it is installed on the device in that it is apparent on examination of the device from outside the device. These include an ice, an intermediate screen or an internal component to the device.
  • the part is delimited by an inner face and an outer face and wherein the first zone covers the entirety of at least one of said faces.
  • the region with a variable light transmission coefficient is thus formed by one of the two faces constituting the part, these faces being the parts of the part which extend in a concurrent and distinct plane with respect to the light source.
  • the part is delimited by the internal face and the external face and the first zone partially covers at least one of said faces so as to delimit a second zone distinct from the first zone, the second zone having a invariable light transmission coefficient.
  • the area with variable light transmission coefficient does not occupy the entire face, the remaining part being formed by the part through which the light beam is not altered by a controllable device.
  • part of the room and more specifically the second zone is substantially at the right of the light source while the first zone may be adjacent to the second zone is thus make invisible to the user some mechanical parts of the projector equipped with such a room.
  • the first zone covers between 10% and 90% of the face concerned. This slice of value guarantees a good level of opacity or reflection while leaving the second zone of the room transparent.
  • the first zone covers at least 30% of the face concerned.
  • the first zone covers a periphery of the face in question.
  • This periphery takes the form of one or more continuous or interrupted bands around the second zone whose luminous transmittance is invariable.
  • the first zone covers the inner face of the piece.
  • the inner face of the part in particular the ice, is the face turned towards the housing of the lighting device. It is thus understood that the first zone is installed on the part but inside the projector so as to protect the device implementing the variability of external aggression.
  • the variability of the light transmission coefficient of the first zone is operated by an electrochromic device, this term encompassing in particular in the description below an electronic ink comprising suspended particles (of the English “Suspended particles device ").
  • This electrochromic device behaves like a capacitor controlled by an electronic control device whose function is to apply to the electrochromic device an electric charge.
  • This electrochromic device takes the form of a solid layer having a thickness of between 500 nm and 10 ⁇ m of the face in question, advantageously 1 ⁇ m.
  • solidarity for example means a bonding of the layer on the inner face or on the outer face.
  • molecular adhesion is also understood to mean vacuum deposition, but any other means for connecting this layer to this face enters the field of the integral word.
  • This layer comprises for example tungsten oxide particles in suspension, the position in the layer is reversible when an electric charge is applied thereto.
  • the invention finds particular application when the part is a transparent or translucent element constituting the lighting and / or signaling device.
  • These include the ice which defines an internal volume of the device relative to the outside of the latter.
  • the invention also finds an interesting application when the part is an intermediate screen, for example installed in the internal volume of the device.
  • the invention also covers a lighting and / or signaling device comprising a first source emitting a light beam installed in an internal volume delimited by a housing and a room according to any one of the characteristics mentioned above.
  • the light beam crosses the first zone. It is thus possible to make the beam visible by driving the first zone.
  • the light beam crosses a second zone distinct from the first zone, the second zone having an invariable light transmission coefficient. This reduces the area covered by the first zone to the bare minimum necessary to hide the condensation or mechanisms of the internal components of the projector.
  • the lighting and / or signaling device comprises a second source emitting a light beam, said first zone being installed in line with the light beam emitted by the second source.
  • This second light source can be a town lamp, a flashing light or a dedicated daylight.
  • the first controllable area can make apparent an additional function embedded in the lighting device without rendering transparent the rest of the room.
  • the variability of the light transmission coefficient of the first zone is operated by an electrochromic device whose opacity or reflection is activated when the first light source is extinguished.
  • the activation that is to say the opaque or reflective, or the deactivation, that is to say the transparent nature of the area, are placed under the control of the ignition of the first light source.
  • the first area becomes transparent so as not to hinder the passage of the light beam.
  • the first zone has a variable light transmission coefficient so as to become, in a predetermined manner, transparent or reflective.
  • the variability of the light transmission coefficient of this first zone is operated by an electronic ink comprising suspended particles (of the English "Suspended particles device” or SPD).
  • This characteristic offers the advantage of being able to reflect rays coming from the sun without absorbing them.
  • the lighting and / or signaling device is able to be mounted adjacent to a body of a vehicle, said body having a hue
  • the lighting and / or signaling device is innovative in that the variability the light transmission coefficient of the first zone is operated by an electrochromic device comprising particles of a hue identical to that of the body of the vehicle.
  • a first advantage of the invention lies in the ability to hide the water droplets resulting from the condensation that forms in a motor vehicle headlight.
  • Another advantage lies in the possibility of avoiding the use of an additional part such as a mask because the controlled light transmission zone can be placed on the part so as to mask the mechanisms of the internal components of the projector. If a mask must nevertheless be kept in the projector, the invention extends its life by blocking the sun's rays may burn the mask.
  • the figure 1 illustrates a lighting and / or signaling device or projector 1 dedicated to a motor vehicle.
  • This device comprises a housing 2 which forms the rear part of the projector 1.
  • This housing 2 is made from a plastic material and comprises a recessed area which forms an internal volume 3 open on one side.
  • the internal volume 3 is closed by a part 4.
  • the latter is for example a transparent or translucent element.
  • the piece is an ice, in particular made of a transparent material such as glass or a plastic such as polycarbonate.
  • This piece 4 can also be an intermediate screen, that is to say a component installed in the internal volume 3.
  • a first source 5 emitting a light beam 6.
  • This source is for example an incandescent lamp, a Xenon lamp or one or more light-emitting diodes. Part of the light beam passes directly through the room 4 and another part of this beam is reflected by a reflector 7 mounted in the internal volume 3 around the first source 5.
  • Part 4 comprises a first zone 8 which has a variable light transmission coefficient. It is understood here that this first zone 8 can be controlled so as to allow or prohibit the passage of a light beam therethrough. The control or control of the light transmission variability of the first zone is operated electrically.
  • the first zone 8 covers only part of the room 4.
  • the room 4 comprises a second zone 9 distinct from the first zone 8 but adjacent to the latter. This second zone 9 is inert in the sense that its light transmission coefficient is invariable, that is to say incapable of change under voluntary action.
  • the first source 5 and the reflector 7 are arranged so that the light beam passes through mainly or only the second zone 9 because the first zone 8n, the variability of the light transmission of which is controllable, is not intended to form 6.
  • the first controlled zone 8 prevents the introduction of the external light rays 10 to the projector from penetrating inside the internal volume 3. This first zone therefore makes it possible to make the outside invisible. part of the internal volume.
  • the piece 4 in particular the ice, has a curved shape and is delimited by an inner face 12 and an outer face 13.
  • the inner face 12 is turned towards the internal volume while the outer face 13 is opposite to the inner face 12.
  • the outer face 13 faces the external environment of the projector 1.
  • the part 4 is finally delimited by a peripheral edge 14 which borders the workpiece 4 and which connects the inner face 12 to the outer face 13.
  • the first zone 8 has a light transmission whose variability is implemented by means of an electrochromic device 11.
  • the electrochromic device 11 extends on the inner face 12 but the invention also covers the case where the electrochromic device is installed against the outer face 13 or both against the inner face 12 and the outer face 13.
  • the electrochromic device 11 takes the form of a thickness layer between 500 nm and 10 ⁇ m integral with the face in question. Preferably, a thickness of 1 micron is perfectly adapted to the application. In practice, this layer is formed of a plurality of sub-layers which number for example three in number, not including transparent electrodes. In this embodiment, it is the inner face 12. This layer can be sprayed on all or part of the inner face 12 of the part 4. In general, the electrochromic device, and particular particle layer, is affixed to the inner face 12.
  • the electrochromic device is electrically controlled so as to become transparent when it is powered or when it receives a electrical discharge of power while it becomes opaque or reflective when it is no longer electrically powered or when it receives a reverse electric discharge to the electric discharge of supply. In this way, when the ignition of the vehicle is cut off and the projector is no longer powered, the electrochromic device is opaque or reflective.
  • the figure 2 illustrates this particular provision.
  • the projector 1 is shown from the front, the part 4, for example ice, being mounted in a sealed manner on the housing 2.
  • the part 4 is delimited by its external face 13, its inner face 12 and its peripheral edge 14.

  • the electrochromic device 11 is here installed against the outer face 13 of the part 4 and, as in the variant of FIG. figure 1 , covers the first zone 8 peripherally.
  • the first zone 8 forms a strip which runs on the outer face 13 adjacent to the wafer 14.
  • the second zone 9 is formed by a central part of the part 4 and this second zone is crossed by the light beam emitted by the first source 5.
  • the figure 3 shows the lighting and / or signaling device 1 installed on a vehicle.
  • the first zone 8 covers the entirety of the part 4 by implementing the electrochromic device over the entire surface of the internal face or the external face of the part 4. This is a a situation in which the electrochromic device is rendered opaque or reflective when the first source is extinguished.
  • the electrochromic device when the first source is powered, for example by lighting the town lamp, low beam or high beam function, the electrochromic device varies the light transmission coefficient so as to make room 4 transparent and thus allow the passage of the light beam provided by the first source. It is thus understood that the light beam intersects the first zone 8 at least at a time when its light transmission coefficient allows the passage of the beam, in other words when the first zone 8 is translucent, advantageously transparent.
  • the projector 1 is mounted adjacent to a body 16 of a vehicle.
  • the electrochromic device comprises particles that prohibit or allow the passage of the light beam. These particles are tinted so as to maintain an aesthetic uniformity between the bodywork 16 of the vehicle and the part 4. To do this, the color of the particles is identical to the shade of the bodywork 16.
  • the figure 4 illustrates a second variant of the lighting device and / or signaling 1.
  • This variant is close to those of Figures 1 and 2 in that the part, for example ice or an intermediate screen, comprises a first zone 8 which has a variable light transmission coefficient and a second inert zone 9, that is to say the light transmission coefficient of which is fixed or invariable.
  • the second zone 9 takes a semicircle shape described substantially in the center of the room 4.
