Definitions

  • the present invention relates to an optical system, particularly for a motor vehicle, such as a lighting and / or signaling device including a photometric function useful for the road traffic of the vehicle, allowing the vehicle to be seen by other vehicles or the driver of said vehicle to see outside.
  • a motor vehicle such as a lighting and / or signaling device including a photometric function useful for the road traffic of the vehicle, allowing the vehicle to be seen by other vehicles or the driver of said vehicle to see outside.
  • Traditional visual signaling or motor vehicle lighting systems include a housing enclosing a point source of light such as a bulb and an optic to focus the beam in a main direction.
  • the outer face of the case can have various shapes and can for example harmoniously extend the curves of the body which contributes to the aesthetics of the vehicle
  • OLEDs organic light-emitting diodes
  • conventional OLEDs have a luminance that is too low to be used in a signaling or road lighting application.
  • the luminance provided by conventional OLEDs is of the order of 1000Cd / m 2 while it would be necessary to obtain 5000 to 10000 Cd / m 2 to satisfy the photometric regulation requirements for road signs.
  • the document FR 2 926 677 discloses an organic electroluminescent diode device emitting a light beam having a high directivity.
  • Such an organic light-emitting diode comprises between these two electrodes various layers, in particular a light emitting layer, a layer promoting the transport of electrons to the emitting layer and a layer promoting the transport of holes to the emitting layer. All of these layers constitute a microcavity whose thickness is adjusted to create an optical resonance. It results from such a structure an emission of a beam of light having a high directivity.
  • These modified OLEDs have several disadvantages which are particularly disadvantageous.
  • These organic light-emitting diodes today comprise small molecules, because they are the most effective and more suitable for carrying out a signaling function in a limited space, for example a rear fender of a vehicle.
  • these molecules must be protected from water and oxygen molecules, which is achieved with glass slides.
  • the OLEDs used to carry out a signaling function therefore comprise a protective glass slide in contact with the emitting layer. Glass slides strongly limit the possible shapes of organic light-emitting diodes.
  • OLEDs must therefore have flat surfaces or at the edge of the set surfaces and therefore they can not consist of a screen having any left surface such as a running mirror of a lighting and / or signaling device of a vehicle automobile. This poses therefore design problems.
  • the preferred beam emission direction is necessarily normal to the OLED plane.
  • the present invention proposes to solve at least one of the problems of the prior art mentioned above.
  • the invention provides an optical system for a motor vehicle, in particular a signaling and / or lighting device defined by the set of claims.
  • the output face perceived by an observer as the emitting surface can be freely inclined and oriented relative to the preferred optical direction.
  • the main direction may also be distinct from the privileged direction.
  • the invention thus offers great freedom of choice as to the shape of the external faces of the vehicle.
  • inclined and / or curved guide exit faces may be provided to follow the curve of the vehicle bodywork.
  • the invention has the advantage of offering a very homogeneous distribution of light over the entire output face, that is to say that the entire surface of the output face provides the same luminance in a direction considered. Thus an observer does not identify discontinuity on the exit face and this regardless of its direction of observation. This advantage enhances the visibility of the vehicle and improves its aesthetics.
  • the optical system according to the invention makes it possible to maintain the same homogeneity characteristics as those of the surface source.
  • the surface source is very homogeneous, as is the case of OLEDs, the output face will also be very homogeneous.
  • the invention also relates to a searchlight or a traffic light of a motor vehicle comprising an optical system as previously described.
  • the invention also relates to a vehicle equipped with a motor vehicle optical system according to any one of the preceding characteristics.
  • the vehicle comprises a body having a substantially continuous shape at the junction between the outer face of the optical system or illumination and the body. That is, the outer surface of the optical system is in the outer extension of the bodywork.
  • the optical system of a motor vehicle in particular a signaling and / or lighting device according to the invention is designed to emit a light whose intensity is maximum in a given preferred optical direction.
  • This preferred optical direction 20 is imposed during the design of the system. In practice, this direction is usually horizontal.
  • this main optical direction generally corresponds to the axis of the road at or in front of the vehicle or to the direction of the vehicle. moving the vehicle.
  • the main optical direction can also be defined by a mapping system, or a steering wheel or wheel rotation sensor, or a road curvature sensor (white line sensor, etc.).
  • the system has an external face that is not contained in a plane substantially normal to the preferred optical direction 20.
  • This outer face can thus be inclined or not with respect to the optical direction privileged, flat or not, etc.
  • the system includes a surface source of light.
  • a surface source of light is a source whose light-generating zone is on a surface. This source is not punctual and differs in this sense from traditional sources of light, for example a bulb. Indeed, in a bulb the light generating zone is limited to the filament of the bulb. For example, this surface source may have an area greater than 1 cm 2 , or even 10 cm 2 .
  • the surface source may for example be an organic light-emitting diode usually designated by its acronym OLED.
  • OLED organic light-emitting diode
  • an OLED is a diode generally composed of a layer of semiconducting organic material, comprising, for example, carbon, hydrogen, oxygen and nitrogen atoms, interposed between a metal cathode and a transparent anode.
  • This multilayer assembly rests on a substrate most often made of glass or plastic. When traversed by an electric current, the layer of organic semiconductor material emits light that is propagated out of the OLED through the anode and / or the cathode.
  • the surface source used in the context of the invention is arranged so that the light emitted is maximum in a direction substantially normal to the front wall of the OLED.
  • the organic light-emitting diode device 60 shown comprises a diode
  • the organic electroluminescent diode 62 comprises a plurality of layers: a cathode 63, an anode 65 and an organic layer 64.
  • the organic layer When the organic layer is subjected to an electrical voltage, it emits a light radiation 66 propagating through the anode 65 which is transparent relative to this radiation.
  • the organic layer may optionally comprise different layers 641 to 645 of different organic materials.
  • organic light-emitting diodes comprising additional layers are used.
  • the organic layer comprises a stratum 641 promoting the transport of electrons to the stratum 643 and a stratum 645 favoring the transport of the holes, ie absences of electrons, up to the emitting layer 643.
  • the organic layer may also comprise a stratum 642 blocking the holes from the lower strata, 643 to 645, and a stratum 644 blocking the electrons from the upper strata 641 to 643. All of these strata constitutes a microcavity whose thickness is adjusted to create an optical resonance.
  • selective interferential reflectors are made which constitute resonant cavities.
  • an organic light-emitting diode of the type described in the document can be used. FR 2 926 677 mentioned above.]
  • the system also includes an optical guide 1.
  • An optical guide is a part within which light rays propagate from an input face to an output face.
  • Other faces, designated internal faces may provide by internal reflection propagation of rays within the guide to the exit face.
  • the color, the shape or the intensity of the beams are not substantially modified. The observer then has the impression that the entire exit face is illuminated and that this face corresponds to a light source.
  • a guide is not necessarily cylindrical. It generally refers to transparent materials that can be very thick, which includes tubes, tablecloths or massive pieces.
  • the optical guide may be glass or poly methyl methacrylate (PMMA) for example.
  • the system is arranged so that the light emitted by the surface source enters the guide through the inlet face 2 and escapes from the guide through the outlet face 3.
  • the inlet face 2 of the guide at least partially covers the front wall of the OLED 30.
  • the entry face 2 is pressed against the front wall of the OLED 30.
  • the contours of the face The input of the guide is as close as possible to those of the surface source.
  • the exit face 3 is therefore not contained in a plane substantially normal to the preferred optical direction 20.
  • the orientation and the shape of this exit face 3 can therefore be imposed during the design of the vehicle, to respond for example to constraints of style or size.
  • the following examples will show various shapes for the exit face 3. It can be provided that the exit face 3 is rounded, curved, inclined, etc., to follow the curve of the vehicle body.
  • the exit face 3 may form at least in part the outer face of the optical system, the latter directly on the outside of the vehicle.
  • the outlet face 3 of the guide may also marry at least in part the shape of the closing window of a projector box and / or motor vehicle traffic light.
  • this system can be contained in the housing of a headlamp or a signaling light of a motor vehicle, without being in contact with the closure glass of this housing; for reasons of arrangement or aesthetics, this exit face may have a curve imposed by the design of this projector or this fire, for example due to the shape of the housing, the curve of the closure glass, a particular shape desired.
  • the guide is shaped so that the intensity of the light at the output of the system is maximum in a direction substantially identical to the preferred optical direction 20.
  • the invention thus makes it possible to emit from a large surface, perceived as being an illuminating surface, with a luminance satisfactory in the preferred optical direction 20 while avoiding constraints related to the orientation or the shape of the outer face.
  • the external aesthetic of the optical system according to the invention can thus be freely designed.
  • the invention has the advantage of providing a very homogeneous distribution of light over the entire output face 3 regardless of the direction of observation. Thus, an observer does not identify a discontinuity on the exit face 3 which he perceives as being the light emitting surface.
  • the outlet face 3 of the guide is inclined.
  • the guide is arranged so that the light entering through the input face 2 arrives mainly directly to the exit face 3. Reflections on the inner faces 4 of the guide are of course not excluded. However most of the rays arrive without reflection at the exit face 3. The finer the guide, the more the rays are reflected on the walls.
  • OLED 30 is pressed against the inlet face 2 of the guide. It emits an increased luminance in a direction 31 substantially normal to the plane in which it is heard. Typically, this plane corresponds to the OLED plate, that is to say to the layer forming the substrate of the OLED.
  • the input face 2 is oriented relative to the exit face 3 so that the guide deflects the light in the preferred optical direction 20. More particularly, a light beam 7 emitted by the surface source penetrates into the guide by the face 2 and reaches the exit face 3 with an angle of incidence 8 relative to the normal 17 to this exit face 3. By refraction at the exit face 3, the incident light ray 7 is refracted and propagates outwards with an angle of refraction 10 relative to the normal 17 which gives it a direction 9 substantially identical to the preferred optical direction 20.

  • Other forms of closed contour can obviously be envisaged such as a polygonal contour, elliptical etc.
  • the invention also makes it possible to produce unclosed contours or any other geometrical shape.
  • the invention also offers great freedom of choice as to the inclination of the exit face 3.
  • the exit face 3 can also be rounded, curved or curved.
  • the exit face 3 can be both inclined and rounded, curved, curved and so on.
  • the output face 3 constitutes the entire outer face of the system.
  • the outer face 3 is not inscribed in a plane and has reliefs. These reliefs are for example stair steps that provide a visual effect of relief and depth.
  • This contour is for example closed and defines a ring.
  • the invention gives the impression that the light is directly emitted by the outlet face 3 of the guide, which provides an effect of volume and depth original and aesthetic.
  • the manufacture of the system is particularly simple since it is sufficient to cooperate the input face 2 of the guide with the front wall of the OLED 30 and to orient the input face 2 so that the intensity of the the light is maximum according to the preferred optical direction 20.
  • the guide 1 comprises a face of reflection 11 oriented so as to receive the light having penetrated into the guide by the input face 2 and oriented so as to direct this light towards the outlet face 3 by reflection.
  • the guide is shaped so that the light reaches reflection by way of the exit face 3 and is transmitted by refraction through this exit face 3 so as to present a maximum intensity in the preferred optical direction 20.
  • it is thus possible to obtain a satisfactory luminance in the preferred optical direction 20 while avoiding orientation constraints at the output and input faces.
  • the output face 3 is adjacent to the input face 2 and the reflection face 11 is opposite to the input face 2.
