    [0001] A lighting device for lighting and / or signaling of a motor vehicle The technical field of the invention is that of lighting and / or signaling of a motor vehicle. The invention relates more particularly to the design of light assemblies capable of providing a function of direction indicator lights. A motor vehicle is equipped both at the rear and at the front of direction indicators, to signal to other road users the intention of the driver to turn. These direction indicators are regulated as to the color they should emit and the light intensity that must be emitted for correct signage. In addition to these photometric regulatory constraints, manufacturers of light assemblies capable of providing a function of direction indicator lights are imposed aesthetic constraints, both in the form of direction indicator lamps, in their ignition and extinction sequence, only in their aspects seen from the outside of the vehicle when they are turned on and off. In particular, it may be requested that the direction indicator has a discontinuous appearance when turned on. Manufacturers have responded to this last requirement by proposing the addition of a partially opaque screen on the path of the light rays emitted by the light sources. However, this practical embodiment does not allow to meet additional requirements according to which it is desired to obtain, in addition to the discontinuous appearance of the lights when they are lit, a solid and continuous appearance when the lights are extinguished, because of the presence at remains of this partially opaque screen.
    [0002] The invention is part of this dual context of obtaining a specific fire design and optimum photometric quality, and it aims to provide an alternative offering good photometric characteristics at low cost, to 3035182 2 constructions of luminous assemblies known moreover for carrying out a function of indicator lights. According to the invention, a luminous assembly comprises at least one optical guide of light-transparent material able to receive rays emitted by at least one light source and to reflect them, by successive total internal reflections, towards an exit face for the emission of a beam output of the guide along a given optical axis. By optical guide is meant an optical part capable of guiding light by total internal reflection of this light, for example in an input zone to an output zone. And the optical guide comprises at least one housing in which is housed a closure member formed of an opaque material. By opaque, one defines the characteristic of the material according to which it is opposed to the passage of the light. Thus, the presence of the shutter elements blocks the direct propagation of the light rays parallel to the optical axis 15 at the output of the optical guide, so that an outside observer sees a discontinuous beam when the light sources are turned on. It will be possible according to different variants that the shutter elements are matte and absorb the light coming towards them, or that they are made of a reflective material to optimize the quantity of light distributed at the output of the light assembly. By way of example in the latter case, the closure elements may be made of plastic material, and in particular polycarbonate, with a deposit of reflective material by aluminizing, for example. The fact that these shutter elements are reported in housings of the optical guide allows a modularity in the realization of the light assembly, so that the shutter elements 25 may be provided or not depending on the model to be manufactured. It will be possible to provide closure elements in different types of material, while the optical guide is advantageously made of a light-transparent material such as polycarbonate or polymethyl methacrylate, a material commonly referred to by the acronym PMMA.
    [0003] It is expected that the housing has a width at least 2mm greater than the size of the dark spot creating the discontinuity of the beam for the outside observer, this dark spot having a width of about 5 mm. According to different characteristics of the light assembly according to the invention, taken alone or in combination: - the at least one housing is arranged in the thickness of the guide, set back from the exit face; the at least one housing extends substantially along said optical axis; In particular, it may be provided that the greater length of the at least one housing 10 extends substantially parallel to the optical axis; the at least one housing is arranged so that the longitudinal end of the housing close to the exit face is disposed between 5 mm and 15 mm, more particularly between 0.9 and 1.1 mm, of this exit face, and even more particularly 1cm from it; The at least one housing is formed by a hole opening on two opposite faces of the optical guide. the at least one housing is formed by a blind hole on one of the faces of the optical guide. It is expected that the optical guide may have a form of web. By web guide is meant a substantially flat optical guide whose thickness is negligible in front of the length and / or the width. This sheet may be curved and have a given curve. Thus the web has two extended faces separated by a periphery, this periphery defining a thickness of the web, which may be variable, for example decreasing from one end to the other. These extended faces 25 form guide faces delimiting a light ray propagation zone, by total internal reflection on these faces.
    [0004] According to different embodiments of the luminous assembly according to the invention, in particular specific with respect to the constitution of the closure elements, it will be possible to provide that, independently or otherwise, the features mentioned above: shutter is formed by a rib projecting from a support member of the optical guide, in particular so that the shutter element and the support member are integral. Or the shutter element is made by a separate part of the optical guide and the support element of the optical guide. In the latter case in particular, it is possible to provide abutment means between this part and the housing of the corresponding guide in order to maintain the position of the closure element in the housing; It is possible to provide a thickness of the ribs of approximately 4 to 7 mm, preferably 2 to 4 mm, and more particularly equal to 3 mm. The shutter element has a substantially longitudinal shape, with transverse corrugations widening said shutter element, so that the width of said shutter element is substantially equal to the width of the corresponding housing. These corrugations were made to allow for a greater shadow width to thereby form a dotted set shape as desired by the manufacturer. In addition, the corrugated shape makes it possible to stiffen the part and to limit any deformations. In a preferred embodiment of the invention, the optical guide comprises a plurality of housings in each of which is respectively housed a shutter element of opaque material, said housings being arranged in series, in particular in a transverse series, parallel to the optical axis. It can then be provided that the optical waveguide is formed of a plurality of plies and light sources, in a fan arrangement such that the guide 3035182 has separate light entry areas and a common exit face, said a plurality of housings and associated closure elements being arranged such that each lumen is at the junction of two adjacent guide plies. The invention also relates to a luminous device housing the first 5 light assembly as just mentioned. In a particular embodiment of the invention, it is proposed to integrate in such a light device a second light assembly adapted to perform a lighting function and / or signaling different from the function of direction indicator lights.
    [0005] In recent years, car manufacturers have been asked to equip the front of their vehicles with daytime running lights (a device also known by the acronym DRL for "Daytime Running Light"). These daytime running lights are constantly switched on when the high beam or dipped beam is not switched on. Regulation requires that the daytime running lights 15 be extinguished when the direction indicators are lit, so as to make them more visible. It is known to bring together as much as possible the light sets corresponding to the daytime running lights and those corresponding to the direction indicator lights. In this context, the present invention proposes, in a series of characteristics taken alone or in combination, a particular arrangement of a luminous device comprising two light assemblies among which a first luminous assembly such as has just been described for the production of light. 'a function of direction indicator lights. In a particular embodiment, the luminous device may further comprise a second light assembly attached to the optical guide. The opaque shutter member may have an axial portion of height greater than the thickness of the strip guide, this upper portion of said axial portion having a shape capable of forming indexing means of an element of the second set bright compared to the first luminous set. The shutter element is then remarkable in that it acts as a screen halting the propagation parallel to the optical axis of the light rays in the optical guide of the first set of lights, and in that it also plays a role of indexing element 5 common to the two sets of lights for their setting relative optimal position relative to each other. The closure member may for example have a proximal portion and a distal portion distinct in that one of the parts is substantially straight and higher than the other portion, which carries corrugations widening transversely said closure member.
    [0006] The second light assembly may comprise at least one optical guide, for example tubular, capable of emitting light rays at the output of said second light unit, as well as an extended guide support downstream of the guide with respect to the optical axis. ray emission, and the guide support may comprise vertical uprights extending opposite the guide and downstream thereof on the passage of the light rays. The invention furthermore relates to a method for igniting and extinguishing light sources for carrying out a function of direction indicator lights, in which light sources of a luminous assembly such as these are controlled. to be described for the realization of a direction indicator lights function, and in which a successive ignition of the light sources of the light assembly is carried out, from the source located furthest to the interior of the vehicle towards the source located furthest outside the vehicle. Thus, the information given to the road users in front of or behind the vehicle is emphasized, with emphasis on the direction of the change of direction to come. The lighting sequencing 25 that is desired to achieve is particularly visible to the observer because of the presence between each guide sheet of an opaque element blocking the direct propagation of light rays.
    [0007] Other features and advantages of the invention will appear on reading the detailed description of an embodiment which follows and for the understanding of which reference will be made to the appended drawings in which: FIG. partial view, in perspective, of a motor vehicle headlamp in which is implanted a light device according to the invention, the device here comprising two assembled assemblies among which a first luminous assembly for carrying out a function of indicator lights of steering and a second luminous assembly for carrying out a daytime running light function; FIG. 2 is a longitudinal sectional view of the projector of FIG. 1; FIGS. 3 and 4 are perspective views, from above, of various components of the first light assembly of FIG. 1, with FIG. a single sheet optical waveguide; and FIG. 4 which illustrates the same sheet optical waveguide and associated diode carrier printed circuit board; FIG. 5 is a perspective view similar to that of FIG. 4 and which illustrates the optical strip guide and the associated diode-carrying printed circuit board (not visible in the figure) covered on the one hand with a support of the printed circuit board complementing the first light assembly and secondly a support of an optical guide of the second light unit; FIGS. 6 to 8 are in perspective, from below, of various components of the light device, FIG. 6 illustrating the optical strip guide 25 and the associated diode-carrying printed circuit board, FIG. 7 illustrating these two components and FIG. supporting the printed circuit board, and Figure 8 illustrating these three components and the optical guide bracket of the second light assembly; FIGS. 9 and 10 are bottom views, in perspective, of the support of the printed circuit board of the first light assembly (FIG. 9) and of this same support associated with the optical strip guide (FIG. 10); FIGS. 11 to 13 are views from below, in the same perspective as FIGS. 9 and 10, showing in greater detail the cooperation of elements protruding from the support of the printed circuit board (FIGS. 11 to 13) and housings made on the optical ribbon guide (FIG. 12) and on the optical guide support of the second light unit (FIG. 13).
    [0008] The motor vehicle headlamp 1 comprises a light device 2 in which at least one first light unit is provided according to the invention for the purpose of carrying out a function of direction indicator lights. In the illustrated embodiment, the light device further comprises a second light assembly for performing a daytime running light function 6.
    [0009] As can be seen in FIG. 1 and in FIG. 2 in particular, the light device is arranged so that the first light unit is disposed above the second light unit. The first light unit comprises an optical guide 8, able to guide the light emitted by a plurality of light sources 9 (visible in FIG. 2) carried by a printed circuit board 10, this card being fixed on a support 12 rendered integral with the structure of the vehicle. As is particularly visible in Figures 3, 6 and 10, the optical guide 8 comprises a plurality of guide plies 14 each associated with a light source.
    [0010] The guide ply is understood to mean a substantially flat optical guide whose thickness is negligible in relation to the length and / or the width. Each ply is delimited longitudinally on the one hand by a rear reflection face 16 which is a slice of the ply extending vertically and substantially transversely to the rear end of the ply, and on the other hand by a face of outlet 18, which is also a slice of the web extending vertically and transversely, this time at the front end of the web. The exit faces of each sheet are glued to each other so that we can speak of an exit face common to each sheet, this common exit face 18 being generally curved to follow the curve of the projector. Thus, it is noteworthy that the guide plies 14 are arranged substantially fanwise, that is to say that the plies are tangent at their forward longitudinal end and their exit face and they gradually deviate to accommodate their rear longitudinal end a spacing between each light source. Each sheet of the optical guide has an upper reflection face 20, turned towards the light source, and a lower reflection face 22 opposite. It can be seen that the upper and lower reflection faces and the light exit face extend over the entire width of the web. Here, a step 24 forming a vertical drop extends substantially transversely to the center of each sheet so that a proximal zone 26 and a distal zone 28 of the sheet can be distinguished, the proximal zone being close to the light source and located higher than the distal zone near the exit face of the guide. The upper face of the proximal zone comprises an input zone 30 of the light rays emitted by the corresponding light source, indexing fins 32, at least two, arranged substantially perpendicularly with respect to each other, and thrust pads in position 34.
    [0011] The light sources are disposed at the input zone 30 of the associated web. The entrance zone is formed by a substantially conical boss protruding from the upper face of the web, the boss having a substantially parabolic wall extending in the direction of the narrowing away from the upper face of the web to an input face of the rays brought to be opposite the corresponding light source. It is particularly notable that the optical waveguide according to the invention comprises at least one orifice 36 of elongate, substantially elliptical or rectangular shape, passing through the thickness of the guide to form a housing. As illustrated, a housing 36 is advantageously provided at the junction of two plies 14 close to the guide. These housings are set back from the exit face 18, and they are substantially parallel to each other, and parallel to the optical axis 38 (shown in Figures 6 and 9) when the optical guide is mounted on the vehicle. For example, the housing is arranged so that the end of the housing near the exit face is about 1 cm from it. The optical guide 8 is made of a material transparent to light, so that the rays entering the guide through the entry zone 30 are guided, by successive internal reflections against the upper and lower reflection faces 20, 22 towards the exit face 18. The material chosen may in particular be a transparent polymer such as polycarbonate or else polymethyl methacrylate, a material commonly referred to by the acronym PMMA. The ribbon optical guide consists of a wafer of this material, which may be about 6 mm thick. The light sources capable of emitting rays in the optical strip guide 8 consist here of electroluminescent diodes, not visible in the figures, carried by the printed circuit board 10. This card is held in position relative to the optical guide 8 so that each diode is disposed facing respectively an entrance area of each web of the optical guide. Advantageously, it is expected that the color of the light rays emitted by the diodes has an amber hue. The number of these first diodes and their transmission power are calculated as a function of the proximity of the light assembly relative to the other sets and light modules of the projector, so as to comply with the regulations in force which aims to provide the minimum luminous intensity of the daytime running lights and a sufficient luminous intensity of the direction indicators so that they are distinguishable even when the passing or driving lamps are switched on simultaneously.
    [0012] The printed circuit board 10 consists of a plate on which is made, in particular by etching, a series of electrical circuits, said plate comprising a plurality of diodes forming the light sources and a connector 39 to said circuits capable of being connected to a associated control module for transmitting to the diodes ignition control or extinguishing instructions. In the light assembly, the card 10 rests on the stop pins in position 34 of the optical guide, these pads being dimensioned in height so that the light sources carried by the card are arranged at the desired distance from the the entrance zone 30 of each web of the guide. The card has holes 40 able to be traversed by the indexing fins 32 of the optical guide, and it also comprises a central bore 42, for its attachment in the first light assembly. The assembly formed by the printed circuit board and the optical guide is covered by a support 12 secured to its ends of the vehicle structure. In particular, the mounting of the printed circuit board on the support makes it possible to dissipate, in particular by appropriate ribbing, the significant thermal radiation specific to the operation of the light-emitting diodes. Support 12 has a substantially horizontal top wall 44 when mounted in the projector and a front wall 46 extending substantially perpendicularly downwardly to the top wall. The support is sized so as to cover the exit face of the optical guide with a surface continuity between the front wall of the exit face.
    [0013] The support comprises a central bore 48 disposed on the upper wall so that this central bore is disposed in line with the central bore 42 formed on the printed circuit board to allow the passage of fixing means, particularly by screwing. The upper wall further includes a plurality of openings 50 for cooling the printed circuit board and a sleeve 52 projecting perpendicularly from the upper wall towards the outside of the support, to allow the passage of control cables to be connected to the electrical connector. of the printed circuit board. The upper wall 44 of the support has an outer face 54 and an inner face 56 facing the printed circuit board, and the inner face is here specific in that it has closure elements 58 and stop pads 60 Each of the closure members 58 consists of ribs projecting from the inner face that extend substantially in the optical axis when the device is mounted as a projector. According to the invention, these closure elements 58 are opaque, that is to say that they are made of a material that does not allow light to pass through, either by total reflection or by absorption, and they are The presence thereof in the sheet guide creates closed areas which will result in a discontinuous appearance of the lighting for an outside observer.
    [0014] It is provided that the ribs have a height, i.e., a dimension projecting from the inner face, at least equal to the depth of the housings so that each rib can completely fill the hole forming the corresponding housing in the housing. guide. The number of ribs is advantageously equal to the number of these housings, which is equal to five in the illustrated example. It will be understood that these closure elements are sufficiently rigid so that they are not twisted at the outlet of the mold during their manufacture, which could, on the one hand, imply an embodiment of the optical function of shutting off the incorrect light. and on the other hand to prevent their insertion in the housing of the guide.
    [0015] As is particularly visible in Figures 9 and 11, each rib has a proximal portion 62, facing the light source, and a distal portion 64, near the light exit face of the light assembly.
    [0016] The proximal portion 62 has a greater height than the remainder of the rib, and extends parallel to the optical axis. The distal portion 64 has at least one corrugation transverse deformation 66 with respect to the main axis of the rib, and has, as described above, a lower height than that of the proximal portion.
    [0017] As will be described below, the width of the rib 58 is smaller than the width of the corresponding housing 36 formed in the optical guide, and the corrugations 66 of the rib are dimensioned so that the resulting enlargement corresponds substantially to the width of the dwelling. It will be understood that it is particularly advantageous to have chosen undulating ribs rather than solid ribs since this makes it possible, for a given width of a housing that it is desired to fill the rib, to avoid injection. a regular bar with too large injection thicknesses all along the rib that could generate appearance defects and deformations. The assembly of the first luminous assembly 4 according to the invention, in particular used in a preferred application for carrying out a direction indicator lamp function, is carried out in this way. The connector 39 of the printed circuit board is connected to control cables passing through the sleeve 52 of the support and the card 10 is then attached against the inner face 56 of the upper wall 44 of the support, 25 by screwing through the central bores 42 and 48. The optical guide 8 is attached against the abutment pads 60 and 34 of the support and the printed circuit board, by cooperating on the one hand the indexing fins 32 of the guide in the corresponding holes 40 of the printed circuit board 3035182 14 and by matching on the other hand the closure elements 58 of the support in the corresponding recesses 36 of the optical guide. It is understood that the widening of the closure elements at their distal portion 64 and its corrugations 66 ensures frictional locking of the transverse ends of these corrugations against the transversely delimiting edges of the housing. The printed circuit board 10 is also fixed on the support 12 by fastening means, of the screwing or bonding type in particular, and it may be noted that in this working position, as can be seen in FIG. proximal portion 62 of the ribs 58 protrudes from the printed circuit board when the latter is attached to the support. We will now describe the operation of the first light assembly 4 according to the invention. When the associated control module receives information relating to the start of the function of direction indicator lights, whether following a command from the driver or following the automatic detection of a change of direction of the vehicle, the control module sends an ignition control command of the diodes. In a first variant of application, the set of diodes is simultaneously controlled by periodic ignition to achieve a steady flashing lights. The rays emitted simultaneously by each of the sources are diffused in the optical waveguide via the entry zone of each corresponding ribbon, and the radii are diverted inside the ribbon towards the exit face of the guide by means of successive internal total reflections against the 25 walls of the web. The spokes are directed over the entire width of the web and it is understood that the portion of the width of the web in which the rib extends does not allow the passage of rays and the direct projection of light rays at the output of the projector. Some rays are thus blocked by the ribs, and thus creates a zone of lower illumination downstream of these ribs, at the junction of two adjacent plies. For the observer in front of the vehicle, the beam projected by the light module for the direction indicator lights function is cut at intervals, regular or not, according to the spacing provided between the housings and the neighboring ribs, of a strip 5 vertical black. This band resulting from the area of least light is at least dark, if it is not completely black, because of the passage of some deviated rays inside the web between the downstream end of the rib and the guide face. As has been previously described, the thickness of transparent material present downstream of the ribs is calculated so that, on the one hand, the presence of opaque, dark ribs is not observable from outside the vehicle when the module does not realize lighting and / or signaling, and that on the other hand, little angle is offered to the rays reflected in the sheet and that the reflected rays which pass downstream of the rib are sufficiently inclined relative to the optical axis to maintain the impression of a zone of less illumination. In a second variant of application of the invention, a successive ignition of the light sources of the light assembly is carried out from the source located furthest to the inside of the vehicle to the source located furthest from the outside of the vehicle. vehicle, so as to accompany the direction of change of direction. It will be understood that in both cases of application, the arrangement of the light assembly, and in particular the position of the ribs embedded in the thickness of the optical guide, makes it possible to obtain successive zones of lesser illumination along the all of which are visible only when the diodes are lit, and it is understood that the fact that the ribs are embedded in the mass makes them invisible from outside the vehicle when nothing is lit. In the different cases of application as well as in the various embodiments of the structure of the light assemblies, non-represented variants may be provided and some of them are described below, without however this list being exhaustive: ribs may not be carried by the plate support as shown in the figures. By way of non-limiting example, they could be carried by the hood of the vehicle coming into overlapping of the light module, or by any other structural component. In a particular variant, it can be provided that the closure elements do not consist of ribs projecting from a structural component of the vehicle but that they are made by independent parts that can be placed one by one by an operator. during assembly in the housings made in the optical guide, the housings and / or shutter elements then being designed so that the closure elements are blocked vertically: the closure elements may include an upper flange which rests abutting against the upper face of the optical guide, or the housing will not open but blind being understood that the thickness of transparent material in the housing will be minimal so as not to let many rays pass under the closure element. Having a rib distinct from the optical guide and the optical guide support member allows this rib to be made of a material different from that of the support, which greatly improves the absorbing and / or reflective properties of these ribs, and to be able to play as well on the function of lighting as on the style of the luminous whole. As may have been mentioned above, the luminous device 2 according to the invention may comprise, in addition to a first light assembly 4 as just described, a second luminous assembly 6 attached to the first luminous assembly and which allows a daytime lighting function. This second light assembly 6 comprises in particular a tubular optical guide 68, housed in a guide support 70 adapted in particular to ensure the fixing of the guide at its ends.
    [0018] In known manner, the tubular guide has a ray entry face at one end of the tube and an outlet face 72 formed by a portion of the cylindrical side wall of the tube. It also has a face, opposite to the exit face, constituting a reflection face of the current rays in the guide, and comprising, for example, prisms which return the rays towards the exit face at an incident angle allowing their refraction out of the guide, and out of the module to perform the desired lighting and / or signaling function. The guide support 70 comprises, upstream of the guide with respect to the optical axis of this second light unit, a reflecting surface against which the reflection face is supported, and it is extended axially to present, this time downstream. of the guide relative to the optical axis, solid uprights 74 which extend into the projected beam output of the guide. An optical effect of dark stripes on the projected light is thus created, it being understood that the vertical uprights are also visible when the daytime running lights are extinguished. The guide support according to the invention comprises an upper face 76 which carries second housings 78, for indexing on the first light assembly of the guide support and the associated guide.
    [0019] The second housings are parallel one by one and substantially parallel to the optical axis, and they are equal in number to the number of ribs 36 made in the first light assembly. These second housings have an axial dimension substantially equal to the length of the proximal portion 62 of the ribs carried by the support 12 of the first luminous assembly 4. As previously stated, this proximal portion 62 of the ribs has a height greater than the thickness of the optical strip guide 8, so that it exceeds in height the optical guide of the first set of light after fitting this guide on the support. And the upper portion of this proximal portion has a shape adapted to form an indexing means of an element of the second light unit with respect to the first light unit. It is therefore of particular interest that, when the light module is applied to a motor vehicle with the two light assemblies, the ribs serve, in addition to their role in the discontinuity of the signaling beam emitted by the first light unit, to indexing. two sets of light compared to a common reference frame. The foregoing description clearly explains how the invention makes it possible to achieve the objectives that it has set itself, and in particular to propose a light module enabling the production of a beam of indicator lights which is discontinuous, cut vertically by dark bands, to propose such a module for which the observer has the impression that the ribs enabling the realization of these dark bands are not permanent in the module, and to propose such a module with means for realizing this impression of retractable ribs which are simpler than mechanical means of displacement of the ribs. It should be noted that the method of igniting the sources of the corresponding light unit is particularly interesting in that it allows one to one ignition of the light sources from the inside to the outside of the vehicle, which accentuates vehicle movement information in the direction of the turn. Of course, various modifications can be made by those skilled in the art to the structures of the light module, which have just been described as non-limiting examples, as long as it is possible to create dark strips 25 in the beam lighting and / or signaling of a motor vehicle, by shutter elements arranged in a light-transparent optical guide. The embodiment which has been described in detail above is not limiting of the invention. In any event, the invention can not be limited to the embodiment specifically described in this document, and extends in particular to all
