LIGHT SOURCE SUPPORT WITH A REFERENCING ELEMENT EXTENDING ON TWO AXES.
FR 3 056 682 - A1
The present invention relates to a support (20) for a light source (11) of a motor vehicle light device comprising:
- a light source positioning area,
- referencing elements (39, 36, 50) along three given axes (Z, X, Y) transverse to each other, one of the referencing elements, known as referencing element in two portions (50), comprising:
O a first portion (51) extending along or parallel to a first (Z) of the three given axes, and
O a second portion (52) extending transversely with respect to this first given axis (Z).
LIGHT SOURCE SUPPORT WITH A REFERENCING ELEMENT EXTENDING ON TWO AXES
The present invention relates to the field of light source supports intended to be mounted in vehicle light devices, in particular for cooperating with a shaping optic receiving the light rays from the light source that they are intended to support.
Vehicle light devices are known comprising a shaping optic arranged to return the light rays coming from a determined zone in the light device, so as to give the light beam a given photometry, in particular regulatory photometry.
Also, when mounting the light source in the light device, it is important that this light source is mounted precisely in the determined area and according to a precise orientation in the three dimensions of the space.
For this, the light source supports include referencing elements along three given axes transverse to one another, in particular three axes orthogonal to each other. These referencing elements are arranged to come into contact with other referencing elements arranged in the light device. The referencing elements along one of the three given axes of the light device are arranged to, when in contact with the corresponding referencing elements of the support, block the movement of the support along this given axis and leave the support free to move along the other two axes, thus allowing adjustment on the other two given axes. These different referencing elements of the support and of the light device are arranged so that, when they are all in contact, the light source is in the given zone.
For this to work, the light source must also be correctly positioned on the support with respect to these referencing elements of the support.
The mounting of the light source, in particular in the case of light-emitting diodes, also called LEDs or LEDs, on a light support can be automated. For this, a robot can be associated with an image capture device coupled to an image processing means. The latter is coupled to a robot control means. The vision device may include a single camera capturing two-dimensional images.
The optical axis of the camera lens can be aligned along a first given axis. In the case of an LED placed on a flat surface of the support for this LED, this first given axis is preferably an axis perpendicular to this flat surface, for example a vertical axis. As a result, the images captured will allow precise detection of the positioning of the area in which to place the LED along the other two axes and therefore in relation to the referencing elements visible in the plane including the planar surface.
However, the support may have a shape such that with such an automation system, certain referencing elements will not be visible because aligned with a portion of the support in a direction parallel to the axis of the optics of the camera. This is for example the case when a referencing element extending in a wall of the support parallel to the first given axis, therefore for example an axis perpendicular to the surface on which the LED is placed.
As a result, the positioning of the LED on its support will be imprecise. Subsequently, even if the mounting of the support in the light device is precise, the positioning of the LED relative to the shaping optics will be imprecise.
The technical problem which the invention aims to solve is therefore to find a method of mounting a support for light sources in a light device which is more precise.
To this end, a first object of the invention is a light source support for a motor vehicle light device comprising:
- a light source positioning area,
- referencing elements along three transverse given axes, one of the referencing elements, called the referencing element in two portions, comprising:
o a first portion extending along or parallel to a first of the three given axes, and o a second portion extending transversely with respect to this first given axis.
Thus, by aligning a camera capturing two-dimensional images with the first portion, or aligning it along an axis parallel to the first given axis, the second portion will be visible by this camera, and this in a precise manner relative to the referencing means. .
Furthermore, even if this referencing element is aligned in two portions with a portion of the support in a direction parallel to this first given axis, the referencing element in two portions will remain visible from the camera. This therefore makes it possible to use a camera for the precise fixing of the LED even with supports having such an alignment, for example a support with a wall perpendicular to a positioning surface of the LED, the first portion of this referencing element in two portions being arranged in this wall.
The light module according to the invention can optionally include one or more of the following characteristics:
- the support includes:
o a first surface extending transversely to the first given axis and comprising said second portion and said positioning zone, and o a second surface which is oriented towards the side of the first surface, is transverse to the first surface, extends along or parallel to the first given axis and comprises said first portion;
by transverse faces means faces included in transverse planes and intersecting them, these faces not necessarily intersecting; this support allows more precise positioning in a light device by positioning each of the surfaces with respect to the shaping optics, for example on a support plate of this shaping optics or directly on the latter;
- The support comprises a wall comprising the second surface, the first portion being a hollow formed in the wall and opening into the second surface; so although the first portion is not visible by a camera whose lens is aligned with the second surface, the second portion will be visible and by positioning the light source relative to this second portion, this second portion will also be positioned by relative to the first portion and therefore relative to the referencing element in two portions;
- the first surface includes the other referencing elements; thus it is easier to position the light source relative to all of the referencing elements;
- The first surface is planar and extends along a first plane, and the second surface is planar and extends along a second plane, the first plane and the second plane being transverse to each other, in particular substantially perpendicular to each other; this facilitates the positioning of the support in the light device;
the first surface and the second surface meet by a fold or a curved portion, said referencing element in two portions being a hole straddling the first and the second surface, the part of the hole on the first surface forming said second portion said referencing element in two portions and the portion of the hole on the second surface forming said first portion of said referencing element in two portions; the hole is therefore continuous from the first surface to the second surface; this makes it easier to produce the referencing element in two portions in the support, while keeping good precision for the positioning of the second portion;
- The first portion and / or said second portion of said referencing element in two portions is oblong; this type of hole is simple and precise to make;
- the support includes:
a first part in the form of a plate and comprising the first surface, and a second part in the form of a plate comprising the second surface, the two plates being transverse to each other, in particular substantially perpendicular;
it is a simple embodiment of a support;
- The first part comprises at least one tongue comprising a slice extending in a plane substantially perpendicular to a second of the three given axes; the slice therefore forms said second referencing element;
it is a simple embodiment of a referencing means along the second given axis which is also visible by a camera whose lens is oriented along the first given axis; moreover, the tongues can be used for mounting by sliding in slides, ending with a stop extending in a plane substantially perpendicular to the second given axis, so that at the end of sliding the referencing according to the second given axis is done. by abutment of the edges against the stops of the slides;
- The first part comprises at least three bosses projecting from the first surface, the tops of the bosses being coplanar in a plane substantially perpendicular to said first given axis; the section therefore forms said third referencing elements; it is a simple embodiment of a referencing means along the first given axis which is also visible by a camera whose lens is oriented along the first given axis; these vertices once in contact with coplanar surfaces orthogonal to the first given axis will allow a referencing of the first surface along the first given axis;
- The first plate comprises at least two tabs arranged on either side of said positioning zone, each tab comprising a section extending in a plane perpendicular to a second of the three given axes, the bosses being formed on the tabs; thus the referencing along the first given axis can be done by simple sliding of the tongues in slides of the light device, each slide comprising a groove whose sliding walls, against which the tongues and the bosses will slide, are arranged in a plane substantially perpendicular to the first given axis;
- the support is a plate; for example with two plate-shaped parts as seen previously;
the support is 7a metal plate, especially in aluminum or in a aluminum alloy ; this allows to ensure also the cooling function the source of light, and also ease of production of support r - the support is obtained by deformation, especially by folding, bending, or stamping, of a sheet metal plate
comprising a rectilinear oblong hole extending along its length, the deformation taking place around a given direction perpendicular to this length of said oblong hole; thus the support is simpler to produce in two parts, with the referencing element in two portions distributed over these two parts;
- The second surface is substantially perpendicular to a second of the three given axes, called the second given axis; it thus becomes easier to position the second surface and therefore the first surface relative to the first given axis, when mounting the support in a light device;
- the three axes given are orthogonal to each other; this allows easier identification of the positioning area and also easier referencing of the support in the light device;
- The support comprises the light source fixed on the positioning area; the support is thus ready to be mounted in a light device according to the invention;
the light source is an electroluminescent light source, in particular one particularly suited to the invention is in which the
LED case, this positioning of the light source is all the more important;
- the support is a heat sink; this simplifies the design of the support with its light source into a light module intended to be mounted relative to a shaping optic;
- The light source is fixed in thermal contact with the support; this allows for simple cooling of the light source, in particular in the case of an electroluminescent light source.
The invention also relates to a vehicle light device comprising at least support according to the invention.
This vehicle light device can be:
- a road lighting device, in particular a headlamp or a fog light;
- a signal light, in particular; a stop light, a daytime running light, a night position light, a direction indicator;
- an interior lighting device, namely the interior of the passenger compartment of a vehicle, in particular: a ceiling lamp or a wall lamp.
The light device according to the invention can optionally include one or more of the following characteristics:
the light device comprises at least one shaping optic and complementary referencing elements arranged so as to be in contact with the referencing elements of the support, so that the shaping optic receives the majority of the light rays emitted by the light source and return them so as to form a given photometric beam; mounting the support in the light device is simple, since it is sufficient to bring the referencing elements into contact so that the support according to the invention, and therefore the light source, are correctly positioned with respect to the optics of shaping;
- Said complementary referencing elements comprise a projection extending along its length along or parallel to a second of the three given axes, called the second given axis, the referencing element in two portions of the support being a hole in the support, the projection s extending in this hole and having contact zones with the edges of the hole, these contact zones being on either side of the projection and aligned in a direction parallel to a third of the three given axes, called the third given axis; thus by its edges, the hole forms the first referencing means, the latter allowing referencing along the third given axis;
the complementary referencing elements comprise slides aligned along or parallel to said second given axis, and the support comprising tongues housed in these slides and capable of sliding in these slides; mounting is simple; moreover in combination with the preceding paragraph, the hole allows the degree of freedom of movement to be left along said second given axis, facilitating mounting;
- The slides include a bottom end of the slide and extending along a perpendicular to said second axis having tongues each having a wafer extending substantially perpendicular to said second given axis and being in contact with one of the funds; thus by simple sliding to the stop, the referencing is ensured along said second given axis;
- The support comprises at least three bosses distributed on the tongues, and the slides comprise sliding walls extending between the entry of the slides and given plane, substantially the support their bottom, these sliding walls being substantially perpendicular to said first axis given and oriented towards the inside of the slide, the bosses each having a vertex, these vertices being coplanar in a plane substantially perpendicular to said first given axis, the vertices of the bosses being in contact with the sliding walls; thus, the engagement of the tongues and of the bosses in the slides allows a referencing of the positioning zone along the first given axis;
- said first given axis is the vertical axis, said second given axis is the longitudinal axis, said third given axis is the transverse axis; the support is thus positioned in the three directions of space.
The invention also relates to a method of manufacturing a light source support, said method comprising:
a step for positioning a support comprising: a zone for positioning the light source, referencing elements along three given axes being transverse to each other, one of these referencing elements, known as referencing element in two portions, including:
a first portion extending along or parallel to given, and a second a first of the three axes portion transversely with respect to this first given axis, then
a step of placing a camera facing said positioning zone, so that the optical axis of the camera lens is parallel or aligned with said first given axis,
a step of capturing at least one image of the support, extending
a step of identifying in the image of said second portion of the referencing element in two portions and of the other referencing elements,
a step of determining the location of the positioning zone with respect to the positions of said second portion of the referencing element in two portions and to the positions of the other referencing elements,
- A step of placing the light source on said positioning zone.
Thus, this makes it possible to precisely mount a light source on a support according to the invention.
The method according to the invention can optionally include one or more of the following characteristics:
- The support is a support according to the invention;
- the implementation stage includes:
o a substep for positioning a gripper holding the light source between the camera and the support, o a substep for aligning the light source with the positioning zone in a direction parallel to or aligned with said first given axis, o a substep of displacement of the light source in translation towards the positioning zone, until the light source comes into contact with the positioning zone;
this allows simple and precisely guided mounting of the light source on the support;
- The light source is an LED having a light emitting surface and a contact surface opposite its emitting surface; in addition, during the LED alignment substep, the LED is also oriented so that its contact surface is positioned opposite the positioning zone, in particular perpendicular to the first given axis ; for example an adhesive or glue can be arranged on the LED and / or the positioning area;
the step of positioning the support is preceded by a step of shaping the support, this step comprising:
o a substep for producing on and / or in a sheet metal plate a rectilinear and elongated element in a given direction, called the main direction, o a substep for producing second (s) and third (s) elements referencing, o a step of deformation of the sheet metal plate around a given direction, called deformation direction, so as to form a deformation extending according to the deformation and separating on the one hand the plate into a first part and a second part, and separating on the other hand, the rectilinear element into a first portion and a second portion, the first part the positioning zone and this portion, and the second part, transverse to the first part, comprising this first portion , this first portion and this second portion forming said referencing element in two portions;
- The rectilinear element is produced by drilling, machining and / or cutting an oblong hole through the plate, the hole forming the referencing element after the deformation step in two portions.
direction area of comprising second
According to the request, a shaping optic deflects the light rays emitted by the corresponding light source of the device so as to confer on the beam of the light device given photometric characteristics, in particular of a beam of road lighting. The shaping optics may include a reflector, a combination of lenses, a combination of reflectors, or a combination of lenses and reflectors.
In the present application, an electroluminescent light source is a light source implementing electroluminescence. Electroluminescence is an optical and electrical phenomenon during which a material emits light in response to an electric current passing through it, or to a strong electric field. This is to be distinguished from the emission of light due to the temperature (incandescence) or the action of chemicals (chemiluminescence). Such a light source is also designated in the field of lighting by the English terms solid state lightsource.
The invention also relates to a vehicle comprising a light device according to the invention, in particular connected to the electrical supply of the vehicle.
Unless otherwise indicated, the terms "front", "rear", "lower", "upper", "side", "transverse" refer to the direction of light emission outside the corresponding light device.
Other characteristics and advantages of the invention will appear on reading the detailed description of the following nonlimiting examples, for the understanding of which reference will be made to the appended drawings, among which:
- Figure 1 shows a sectional view of a light source support according to the invention positioned relative to a shaping optic;
- Figure 2 shows a perspective view, seen from the front, of part of a light device according to the invention comprising the support of Figure 1;
- Figure 3 shows a perspective view, seen from below, of a light source support according to the invention;

- Figure 6 shows an enlargement of part of Figure 5, still in perspective but in another orientation.
FIG. 1 illustrates a light source support 20 according to the invention, in position in a light device according to the invention. Only the shaping optics 30 of this light device is shown.
In this example, this shaping optic is a reflector 30, having a reflecting surface 30a, oriented towards the front, and an inactive surface 30b, oriented towards the rear.
As can be seen, the support 20 is arranged relative to this reflector 30 in such a way that the light source, here an LED 11, sends its rays rl, r2, towards the reflecting surface 30a. The reflecting surface 30a is arranged so as to send these rays rl, r2 in determined directions so as to form a light beam of a given photometry, in this example an illumination beam.
In this example, the support 20 is formed by a plate comprising a first part 21 and a second part 22. The first part 21 and the second part 22 therefore each have the form of a plate.
In this example, the first part 21 is arranged horizontally when the support 20 and the light device 1 are in position in the vehicle.
The first part 21 comprises a first surface of the support, called the lower surface 23. This lower surface 23 is planar and oriented towards the side of the second part 22.
In this example, the LED 11 is arranged on this lower surface 23 and above the reflecting surface 30.
The second part 22 is also in the form of a flat plate, is substantially vertical and extends transversely.
The second part 22 comprises a second surface of the support, known as the front surface 24. This front surface 24 is flat and oriented transversely and vertically opposite the inactive surface 30b. It is therefore orthogonal to the first surface 23.
As can be seen in FIG. 2, the light device 1 according to the invention comprises a housing closed by a closing glass, this housing and this closing glass not being shown in FIG. 2. Inside this housing , the light device 1 also comprises a plate 46 supporting three reflectors 30, 30 ', 30' ', a central reflector 30, a left reflector 30' 'and a right reflector 30'.
In this example, the plate 46 is formed with these reflectors 30, 30 ', 30' 'in a single piece. In particular, the plate 46 can be formed integrally in one piece with these reflectors 30, 30 ', 30' '.
Here, the plate 46 comprises separating walls 47 separating a reflector 30, 30 ', 30' 'between them. These separating walls 47 can, as here, be masks.
A first support 20, a second support 20 'and a third support 20' 'are arranged at the level of the central reflector 30, the right reflector 30' and the left reflector 30 '' respectively. Each of these supports 20, 20 ', 20' 'is equipped with an LED 11.
In this example, the first and third supports 20, 20 '' and their LEDs are identical. Consequently, they bear the same references in the following figures. However, the second support 20 'and its LED is different. However, this example is not limiting, for example each support could carry different LEDs.
As illustrated in FIGS. 3 and 4, at each support 20, 20 ', 20' 'three given axes X, Y, Z are chosen, along which referencing elements are arranged, capable of referencing the positioning of the support 20 , 20 ', 20' 'relative to the corresponding reflector 30, 30', 30 '' and according to these three given axes X, Y, Z. These given axes are in this example chosen as being perpendicular to each other and intersecting at the level of the positioning zone of the LED 11. They thus form an orthonormal reference mark at the level of this positioning zone, and at the level of the LED 11 when it is placed there.
In FIGS. 3 and 4, the support 20 is oriented inversely with respect to the vertical axis Z, compared with its orientation according to which it is intended to be used in the light device illustrated in FIG. 2. In fact, the orientation in FIGS. 3 and 4, corresponds in this example to the orientation given to the support 20 on an assembly line, before mounting of the LED 11.
Consequently, in FIGS. 3 and 4, the upper face of the support 20 is not visible.
In this example, the support 20 is formed by a metal plate which has been stamped. Initially it was flat and the various holes observable in it can be drilled or machined before conformation of this plate in the form of support 20 illustrated.
Here, the plate has been deformed, for example stamping or bending, so as to give it two transverse parts, namely the first part 21 and the second part 22. As can be seen in these Figures 3 and 4, the two parts 21 and 22 are not entirely adjacent but are interconnected by a curved part 29, which corresponds to the part having undergone the deformation.
This deformation was carried out in this example around a direction parallel to the transverse axis Y, which means that this curved part 29 has a cylindrical shape whose generatrices are parallel to this direction.
According to one embodiment of the invention and as here, initially, in the plate intended to form the support 20 was formed an oblong through hole 50 extending in a main direction K. After the deformation, this oblong hole
50, forms a referencing element in two portions having a first portion 51, arranged in the wall formed by the second part 22, and a second portion 52 arranged in the first part 21, here in the wall formed by the first part 21. Therefore, each of the portions
51, 52 forms a through hole in each of these parts. This oblong hole is therefore continuous and extends from the first part 22 to the second part 21, passing through the curved part 29.
Therefore, the second part 22 includes a referencing element, hereinafter referencing element in two portions 50.
According to this example, the first portion 51 therefore extends in length along a first of the three given axes, namely in this example the vertical axis Z.
According to the invention, as in this example, the main direction K is oriented along an axis parallel to a second of the three given axes, namely in this example the longitudinal axis X.
According to the invention, the edges 53a and 53b of this first portion 51 of this oblong hole 50 can form transverse stops, allowing referencing along a third of the three given axes. This is therefore the case in this example, where this third given axis is the transverse axis Y. The oblong hole 50 therefore forms a referencing element along the third given axis, here the transverse axis Y.
According to the invention, as in the example illustrated, the first surface 23 can also include a printed circuit 15 to which the LED 11 is connected, for example as here, by welded blades 17.
In this example, the LED 11 is mounted directly on a portion of the support 20 remote from the printed circuit 15. However, this is not limiting. Alternatively, the LED can be positioned directly on the printed circuit.
This first part 21 also comprises lateral tongues 34 arranged on either side of the longitudinal axis X. Each of these tongues 34 is coplanar with the part of the first surface 23 supporting the printed circuit 15.
These tongues 34 comprise front sections 36 arranged in the same plane perpendicular to the longitudinal axis X. Therefore, these front sections 36 form a referencing means along the longitudinal axis X, leaving degrees of freedom along the axis transverse Y and along the vertical axis Z.
Furthermore, the surface of these tongues oriented on the side of the second part 22, which is a part of the first surface 23, includes bosses 39. These bosses 39 can for example be produced by stamping. In this example, these bosses 39 project from the first surface 23.
These bosses 39 each have a vertex. All of these vertices extend arranged in the same plane. This plane is perpendicular to the vertical axis Z. As a result, these vertices form referencing elements along the vertical axis Z, leaving degrees of freedom of movement along the longitudinal axis X and the transverse axis Y.
These bosses 39 can, as in this example, be distributed as follows: a front boss on each of the two lateral tabs and a rear boss on each of the two lateral tabs. There is thus better stability in vertical referencing.
According to the invention, and as in this example, these
bosses 39 can be lying down according to a direction parallel at second axis given here 1 axis transverse Y. Each summit forming a parallel line to the second axis
given Y. We further improve vertical referencing.
The second part 22 also includes first and second fixing holes, 56 and 57. The second part 22 and the part 21 have also been shaped so as to have fins 37, promoting heat dissipation, therefore cooling the LED. 11 and electronic components 14 arranged on the printed circuit 15.
When the support is arranged on the assembly line, the image captured by a camera whose optical axis of the lens would be arranged along the vertical Z axis, is as the illustration in FIG. 4.
As can be seen in this figure 4, the first portion 51 of the oblong hole 50, is not visible. In fact, the latter is aligned with the vertical axis Z, and in particular aligned with the wall formed by the second part 22.
However, the second portion 52 is visible. What is more, it is visible by extending in the direction K parallel to the longitudinal axis X. Thus, on the image captured by the camera, an image processing means can easily locate the referencing elements according to the longitudinal axis X, here the front edges 36, the referencing elements along the vertical axis Z, here the bosses 39, but also the referencing element along the transverse axis Y, namely the hole oblong 50 thanks to its second portion 52.
It follows that a means of processing these images will easily identify the positioning area of the LED 11 with respect to the three given axes X, Y, Z.
As a result, it will be easy to control a robot coming to position this LED 11 in a precise manner.
This is particularly suited to the case where the LED 11 is mounted by a placement, also called "pick and place" (for "collect and place" in English). This placement includes the action of placing the LED 11 in a translational movement towards the positioning zone, here in a translational movement along the vertical axis Z. It follows that with a camera and a control means can carry out an assembly of the LED by simple stitching of the latter with precision with respect to the various referencing elements 50, 39, 36 of the support.
These referencing elements 50, 39, 36 make it possible to reference the support 20 with respect to complementary referencing elements 61, 64, 35, included in the light device 1. Thus, the support 20, 20 ', 20' 'of the light source 11 will be positioned precisely with respect to the shaping optics 30, 30 ', 30' 'of the light device 1. Consequently, the light source 11 will be positioned precisely with respect to the shaping optics 30, 30 ', 30.
As can be seen in FIGS. 5 and 6, the three reflectors 30, 30 ', 30 are formed on the plate 46.
This plate 46 comprises means 45 for fixing to the housing of the light device 1, some of which are arranged to allow adjustment of the orientation of this plate 46, when the light device is used in the vehicle.
The reflecting surfaces of the reflectors 30, 30 ', 30' 'have different shapes, so that the light rays of each reflector form elementary light beams of different photometries. These elementary light beams together form the general light beam emitted by the light device 1.
Nevertheless, some reflectors can, as in this example the left reflector 30 '' and the central reflector 30, be arranged so as to receive the light rays of LEDs of identical powers and arranged in an identical positioning with respect to the referencing elements of the support which wears them. The light source supports of these reflectors 30, 30 '' can therefore be reversed.
Also, other reflectors can, as in this example the right reflector 30 ′ and the central reflector 30, be arranged so as to receive the light rays of LEDs of different powers and / or arranged in a different positioning relative to the elements of referencing of the support which carries them. The light source supports of these reflectors 30, 30 ′ must therefore not be inverted.
As can be seen in these Figures 5 and 6, to mount the support relative to the reflector, the transverse tabs 34 of the support 20, 20 ', 20' 'are inserted in slides 32.
In this example, each of the reflectors 30, 30 ', 30' 'comprises at the rear a projection 61 extending from the inactive face 30b of the reflectors 30, 30', 30 '' along an axis parallel to the longitudinal axis X. This projection 61 penetrates inside the first portion 51 of the oblong hole 50. As a result, the support 20, 20 ', 20' 'is free to slide along the slides 32 when it is positioned at the level of the corresponding reflector 30, 30 ', 30' '. Furthermore, this first portion 51 of the oblong hole 50 extends along the vertical axis Z. It is therefore possible to adjust the support along this vertical axis Z relative to this projection 61, and this before the all the bosses 39 are inserted in the slides 32.
Each of the slides 32 includes an inlet 63, these slides 32 being oriented transversely, that is to say that these comprise sliding walls 64 against which the tongues 34 and the tops of the bosses 39 of the support 20, 20 ' , 20 '' can slide.
At the bottom of each slide 32, therefore in this example at the front of each of these, is arranged a bottom 35 along a plane substantially perpendicular to the longitudinal axis X. Thus during the mounting of the support 20, 20, 20 '' on the plate 46, the tongues 34 are first inserted inside the slides 32, by the corresponding input 63 (for reasons of clarity of the figures, only one input is referenced).
Here, these slides 32 are oriented along an axis parallel to the longitudinal axis X. The sliding of the support 20, 20 ', 20' 'in particular from the inside of the slides 32 is longitudinal translation.
In doing so, the bosses 39 located at the front on the tongues 34 are then inserted into these slides 32 and come into contact with the sliding walls 64.
Then, the bosses 39 located at the rear on the tongues 34 in turn enter inside the slides 32. Concurrently or offset, the projection 61 enters inside the first portion 51 of the oblong hole 50. In doing so during the continuation of the sliding, the projection 61 continues to pass through the second portion 52 transversely to the plate forming the second portion 22.
these tabs 34 do so according to a
Then, the front edges 36 come into contact with the bottom 35 of each of these slides 32. Through this contact in a vertical plane substantially perpendicular to the longitudinal axis X, there is thus a referencing along the longitudinal axis X.
Likewise, the bosses 39 being inside the slides 32, and the sliding walls 64 being arranged in a plane substantially perpendicular to the vertical axis Z, the contact of the tops of its bosses 39 with these sliding walls 64, creates a referencing along the vertical axis Z.
Furthermore, at the end of its travel, the projection 61 is such that these lateral edges come into contact with the lateral edges 53a, 53b of the first portion 61 of the oblong hole 50. As a result, the areas of this projection 61 in contact with the lateral edges 53a, 53b are aligned along a transverse axis Y. There is therefore here a referencing along this transverse axis Y.
Thus at the end of sliding, the entire support 20, 20 ', 20' 'and therefore of this light source 11 are positioned relative to the corresponding reflector 30, 30', 30 ''.
According to an embodiment of the invention, for example as illustrated, the referencing elements allow mounting by sliding in slides to reference this support. In the example illustrated, this assembly is facilitated.
This mounting also allows a simple realization of the positioning of the LED on its support prior to the mounting of the latter in the light device, using as benchmarks the referencing elements of the support, without adding other benchmarks or other elements of SEO.
According to the invention, each reflector 30, 30 ', 30' 'can include a barrel 62 extending longitudinally from its inactive surface 30b. The barrel 62 is arranged so that when the referencing elements 50, 39, 36 are in contact with the complementary referencing elements 61, 64, 35, the barrel 62 is in contact with the first fixing hole 56. It it suffices then to screw a screw 33 through this first fixing hole 56 and into this barrel 62 to firmly fix the support 20, 20 ', 20' 'to the reflector. The shape of the support in two transverse parts as well as the slides reinforce this plating.
Also, a lug 62, 62 'can extend longitudinally from the inactive face of each reflector 30, 30'. At the end of positioning, this lug is clipped into the second fixing hole 57. This lug 62, 62 ', is arranged to maintain an electric harness supplying the LEDs of the supports 20, 20' and 20 '', and connecting these the latter to a general internal wiring harness of the housing 1, this general wiring harness being intended to be connected to the vehicle battery.
According to the invention, to avoid the risks of inversion of the support of certain reflectors, here an inversion between the support 20, 20 '' associated with the central reflector 30 or the left reflector 30 '' with that 20 'of the right reflector 30' , the positions of the fixing holes 56, 57 and of the first portion 51 in the second part may be different in these supports. For example and as illustrated, between the second part 22 of the support 20 associated with the center reflector 30 and the second part 22 'of the support 20' associated with the right reflector 30 ', these positions are reversed, that is to say symmetrical according to a plane, here longitudinal. Therefore, the second portion 52 is on the left in the second part 51 'of the support 20' associated with the right reflector 30 ', and on the right in the second part 51 of the support 20 associated with the central reflector 30
According to the invention and as here, the first portion 51, 51 ′ of the oblong hole 50, 50 ′ may comprise a constriction 54,
54 'located between or at the end of this first portion 51, 51' closest to the second portion 52, either at the top in the mounting position in the light device 1. This constriction makes it possible to avoid passing the projection 61,
61 'from the first portion 51, 51' to the second portion 52.
In this example, the support 20, 20 ', 20' 'may include an orifice 38 crossed by a connector 16 connected to the printed circuit 15. In FIG. 5, one can see the connection tracks 18 passing through the hole 38 so as to be connected to connector 16, not shown in Figure 5.
This connector 16 is capable of receiving a connector 40 of a power cable 41.
In order to facilitate sliding, a space 31 can be provided between the reflector 30 and the passage zone 15 of the first part 21.
