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.
- document FR 2 926 677 discloses an organic light emitting 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 system has an outer face that is not contained in a plane substantially normal to the preferred optical direction.
- This optical system comprises:
- a surface source of light having a front wall emitting a light whose intensity is maximum in a main direction of emission
- an optical guide comprising an input face and an output face forming at least part of the external face of the system, the system being arranged so that the light emitted by the surface source enters the guide through the input face and escapes from the guide by the exit face, the optical guide being 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.

- 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 system according to the invention may furthermore optionally include at least any of the following features:
- the surface source of light comprises at least one organic light-emitting diode (OLED or OLED).
- OLED organic light-emitting diode
- the system may include a plurality of OLED juxtaposed to form a surface emission area. This also makes it possible to follow more finely the curve of a closure window of a lighting and / or signaling device, such as a projector, also called a headlight, or a traffic light.
- the front wall of the surface light source is substantially flat.
- the main direction of emission is substantially normal to the front wall of the surface source. This makes it possible to use some highly directive OLEDs technologies, where the OLEDs are covered with a glass slide.

- the input face is disposed directly on the front wall, namely in contact.
- the input face is oriented relative to the output face so that the light entering through the input face reaches mainly directly to the output face.

- the system comprises at least one reflection face.
- This system is arranged so that the reflection surface reflects on the output face the light coming from the input face.
- the system is arranged so that the light entering through the input face is mainly reflected on the reflection face so as to reach the exit face with an incidence that allows the intensity of the light at the output of the system is maximum in a direction substantially identical to the preferred optical direction. The orientation and flatness constraints are therefore transferred to the reflection face.
- the emission area of the surface light source is greater than
- this surface may be greater than 10 cm 2 .
- the light source has a strong emission directivity in the direction perpendicular to its emitting surface, compared to lambertian light emitting diodes.
- the light source In the direction perpendicular to its emitting surface, the light source has a luminance of at least 5,000 Cd / m 2, preferably at least 10,000 Cd / m 2.
- the high directivity of the surface light source is characterized by the fact that the law of light intensity of this source as a function of the emission angle ⁇ , is a law of the type:
- cos (0) A n n
- n a power varying between 10 and 20.
- cos (0) A n means a function of the transmission angle ⁇ , evolving in the same way as the function cos (0) A n
- 0 0 is the main direction perpendicular to the surface of the OLED.
- a portion of the outer face comprises an optical mask partially covering the optical guide so that the portion of the unmasked outer face defines the exit face.
- the exit face is curved or rounded.
- the normal to the exit face is inclined relative to the preferred optical direction.
- the exit face forms an outline, preferably a ring or the periphery of an ellipse or a polygon.

- a signaling function such as: a vehicle position signaling function, a change of direction signaling function, a reversing signaling function, braking signaling, a signaling function position in case of fog.

- 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.
- a method for designing a motor vehicle optical system comprising the steps of:
- an optical guide comprising an input face and an output face forming at least part of the external face of the system, so that the light emitted by the surface source enters the guide through the input face and escapes of the guide by the exit face, define the configuration of the optical guide so that the intensity of the light output of said optical system is maximum in a direction substantially identical to the preferred optical direction.

- Figure 3 is a perspective view of a second example of a system according to the invention.
- Figure 4 is a perspective view of a third example of a system according to the invention.
- FIG. 5 is a sectional view of the third example illustrated in FIG. 4 and in which the propagation of the optical rays of the beam is schematized.
- Figure 6 illustrates an example of an organic light-emitting diode.
- the optical system of a motor vehicle in particular a signaling and / or lighting device according to the invention, is arranged 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 organic electroluminescent device 62 and a voltage generator 61.
- the organic light-emitting diode comprises several layers: a cathode 63, an anode 65 and an organic layer 64.
- a cathode 63 When the organic layer is subjected to an electrical voltage, it emits 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.
- 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.
- FIGS. 1 and 2 A first exemplary embodiment will now be described with reference to FIGS. 1 and 2.
- 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.
- the skilled person by his general knowledge of optics, will know without difficulty calculate the orientation to be given to the input face 2 as a function of the shape and the orientation of the exit face 3, as well as the refractive index of the medium inside which the light propagates. By orienting the input face 2, we obtain a maximum light intensity in a direction substantially corresponding to the preferred optical direction 20, typically the axis of the road.
- the exit face 3 forms a closed contour.
- This contour forms a ring.
- the guide thus comprises inner walls 5 and outer walls 6.
- they are polished and do not include a coating, which is generally sufficient to ensure total reflections within the guide.
- 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 1 1 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 1 1 is opposite to the input face 2.
- Figure 5 comprises a diagram showing the path of a light beam emitted by the surface source.
- the incident ray 7 is emitted by the OLED 30 in a direction 31 normal to the plane in which it extends.
- the spoke 7 then propagates in the guide and arrives mainly directly to the reflection face 1 1.
- the incident ray 7 at the reflection face 1 1 is reflected towards the exit face 3.
- this reflected ray 12 is deflected at the interface formed by the exit face 3 and escapes with a direction substantially identical to the preferred optical direction 20.
- the outlet face 3 is curved.
- the guide also has an opposite face 14 to the exit face 3. This opposite face 14 is also curved. Since this opposite face 14 is not flat, it can not receive the OLED 30.
- the OLED 30 is then placed on a flat surface which, in this example, is adjacent on the one hand to the exit face 3 and to the other. on the other side 14.
- the section of the guide in a plane normal to the plate of the OLED 30 has a quadrilateral shape of which two sides opposite are parallel and one of the other sides is perpendicular to the two parallel sides.
- the input and output faces can indeed be freely oriented.
- the exit face 3 and the opposite face 14 may have totally arbitrary shapes and in particular not contained in a plane.
- This embodiment is for example particularly advantageous for making raised brake lights. These stop lights are often placed against the tailgate window. It is often desirable to release the inwardly facing side of the cockpit from both the OLED 30 and both of the electrical connections thereof.
- the invention makes it possible to postpone the OLED 30 as well as its electrical connections on a face not turned towards the interior of the passenger compartment.
- the invention may also include the following features that may be combined with each of the embodiments described above.
- the outer face may comprise a mask 15 preventing the light from escaping and thus reducing the surface area of the exit face 3. This makes it possible, for example, to stop parasitic rays which would escape from the guide directly in the vicinity of the surface source. This improves the sharpness of the illuminating area of the guide.
- a mask may be constituted by a reflective coating covering a portion of the guide. In the embodiment illustrated in FIGS. 4 and 5, this mask 15 may for example cover the guide from the entry face 2, extend on the exit face 3 and stop on the latter to leave it free only a lower portion. This lower portion corresponds to the main zone on which the rays reflected by the reflection face 1 1 arrive directly at the exit face 3.
- the outer face when the system is mounted on a vehicle, the outer face is disposed in contact with the surrounding environment or is covered by a protective layer, forming for example a portion of a closing window of a housing inside which is housed the system.
- the guide may further comprise diffusing reliefs located within the guide itself and shaped to form volume patterns. These reliefs located inside and / or on the surface of the guide offer many possibilities of style, thus improving and differentiating the aesthetics of the vehicle when the light source is activated.
- the system according to the invention receives for particularly advantageous application a brake light or a turn signal or a reversing light or a stop light raised and centered type CHMSL acronym for Center High-Mount Stop Light.
- Several systems according to the invention can be brought together in the same signaling module and / or lighting, each of the systems providing a signaling function and / or separate lighting.
- a module can indeed incorporate at least two of the following functions: reversing light, brake light, flashing, lighting etc.
- the system according to the invention makes it possible, for example, to ensure good continuity of shape at the junction between the surface perceived as being the emitting surface and the bodywork. It can thus fit perfectly into a highly curved body.
- the invention further relates to a method for designing a display system for a motor vehicle. This process comprises the following steps:
- a privileged optical direction 20 is imposed according to which the intensity of the light is maximum.
- the exit face of the system has impose the shape of the exit face of the system. This shape can be imposed by the aesthetics to give the vehicle, for example to follow the curve of the body.
- the exit face is intended to remain visible from the outside during operation.
- the exit face is not contained in a substantially normal plane of the preferred optical direction 20.
- the front wall of the surface source 30 is covered with the entry face 2 of the optical guide 1.
- the guide 1 is configured by orienting the input face 2 and / or the possible reflection face 1 1, so that the intensity of the output light of the system is maximum in a direction substantially identical to the optical direction privileged 20.
