Definitions

  • the invention relates to a lighting and / or signaling module comprising an LED adapter fixed on its printed circuit intended to bear on the support of a first optical element of this module.

  • the light emitting element may be covered with a transparent protective element, modifying or not the beam emitted by the photoemissive element.
  • optical deflection elements in the present application are optical elements for deflecting the light beams. These are, for example, reflectors, which deflect light by reflecting it, or lenses, which deflect light by one or more refractions.
  • the light source can be associated with a single optical element.
  • a convergent lens or a parabolic reflector at the focus of which is placed the light source.
  • You can also use a combined elliptical reflector a second generally convergent optical element, for example a lens.
  • An example of these optical modules having in addition one or more LEDs as a light source is described in document FR2839139 .
  • the photoemissive element must be positioned precisely with respect to the focus of the first optical element, which collects the rays emitted from the surface of the light emitting element.
  • the support element of the first optical element that also supports the printed circuit, so that by correctly setting this support with respect to the size of the LED and the thickness of its printed circuit, it ensures the positioning of the light emitting element with respect to the focus of the first optical element.
  • Each circuit board is adapted to the electrical characteristics of the LED or LEDs it carries. As a result, LEDs with different characteristics will present different printed circuits. In particular, depending on the LED used, this circuit will generally have a different thickness.
  • the object of the present invention is therefore to find a solution to allow the use of different LEDs of different characteristics for the same optical module of lighting and / or signaling device for a motor vehicle, including the support of the first deflection element Optical also supports an LED fixed on its circuit board.
  • Another object of the present invention is an LED adapter fixed on its printed circuit, in particular for a module as described above.
  • This adapter comprises a first face for fixing the printed circuit, and a second face opposite to the first face, the second face comprising means for receiving a fixing means.
  • This adapter can thus be used in a module as described above to place a given characteristic LED.
  • This optical module may also have a support having a through hole accessible on one side from outside the module and opening to the other in said withdrawal.
  • the term "in the vicinity of the first focus” is intended to be positioned on the focal point or at a distance therefrom such that the ray issuing from the light source emerges substantially parallel to the optical axis. .
  • This distance may for example equal to one-tenth of the focal length of the reflector.
  • the invention also relates to a lighting and / or signaling device comprising an optical module as described above.
  • the invention also relates to a vehicle comprising such a lighting and / or signaling device.

  • the figure 1 represents the different optical elements of the present invention.
  • the lighting module 10 comprises, arranged from rear to front along a longitudinal longitudinal optical axis AA, a first optical deflection element, which is for example as in the example illustrated a reflector 12 of the elliptical type.
  • the lighting module also comprises a light source 14 which is arranged in the vicinity of a first focus F1 of the reflector 12, and a second optical deflection element 16 whose focal plane is arranged in the vicinity of the second focus F2 of the reflector 12.
  • the second optical deflection element is a converging lens.
  • the lens 16 could also be replaced by a parabolic reflector or with parabolic sections, having a focus positioned on or in the vicinity of the second focus F2.
  • the optical axis AA defines here, without limitation, a horizontal longitudinal direction and a back-to-front orientation, which corresponds to a left-right orientation on the figure 1 and from right to left on 2 and 5.
  • the optical axis AA is for example substantially parallel to the longitudinal axis of a vehicle (not shown) equipped with the lighting module 10.
  • An LED 14 emits its light energy in less than a "half space" above the cache surface 22 towards the inner face of the elliptical surface of the reflector 12.
  • the light emitting element is encapsulated in a protective resin dome.
  • the convergent lens 16 is here a piece of revolution around the longitudinal optical axis A-A.
  • the lens 16 has, vis-à-vis the reflector 12, a transverse input surface 17 for the light rays.
  • the reflector 12 comprises an elliptical surface which is formed as a substantially angular sector of a part of revolution, and which extends in the half space above an axial plane horizontal passing through the longitudinal optical axis AA.
  • the elliptical surface may not be perfectly elliptical and may have several specific profiles intended to optimize the light distribution in the lighting beam produced by the module 10, according to the lighting function performed by the module 10.
  • the reflector 12 defines a reflection volume for the light rays emitted by the source 14, that is to say a volume in which the light rays are emitted and in which the light rays are reflected.
  • This reflection volume is delimited, in its upper part, by the internal face of reflection 20 of the elliptical surface, and vertically downwards by the reflecting face of the cache surface 22.
  • the cover surface 22 extends here in a horizontal axial plane.
  • the cover surface 22 is delimited, at the rear, at its intersection a trailing edge, and at the front, by a cutting edge 28. It can be provided alternatively that the cache surface 22 is delimited at the rear by a line segment perpendicular to the axis AA and passing in the immediate vicinity of the LED 14, in front of the latter.
  • the cutting edge 28 of the cover surface 22 is arranged on or in the vicinity of the second focus F2 of the reflector 12, so as to form a sufficiently sharp cut in the illumination beam produced by the lighting module 10.
  • the curved shape of this profile is more or less complex, and can be compared in first approximation to an arc of a circle. Therefore, preferably, the cutoff edge 28 has a curved profile, in the horizontal plane, so as to follow generally the profile of the focal plane of the lens 16.
  • the figure 2 also schematically illustrates an optical module in section substantially identical to that illustrated in FIG. figure 1 .

  • the support 20 described allows thanks to this support surface the placement of an adapter whose configuration will allow this positioning, in a simple manner.
  • This bearing surface also makes it possible to take another LED than that illustrated, fixed on a printed circuit of different thickness. It will suffice to vary the shape of the adapter 70, by changing or machining it without modifying the arrangement of the support 20 and the reflector 12.
  • the support 20 comprises a recess 60 whose bottom is formed at least in part by the bearing surface 61.
  • the depth of the withdrawal is equal to the sum of the thickness of the adapter 70, the thickness of the printed circuit 80 and from the thickness of the underside of the LED to the illuminating face of its photoemissive element 14.
  • the photoemissive element 14 is thus simply by positioning the adapter on the bearing face 61 in the horizontal plane containing the first focus F1.
  • the adapter 70 is particularly interesting because other elements must also be correctly positioned relative to the focal points of the reflector 12, namely the converging lens 16 and the cutting edge 28.
  • the light rays R1 from the focus F1 are reflected at the second focus F2 of the reflector that corresponds to that of the lens 16.
  • the lens then refracts the radius R1 parallel to the optical axis AA.
  • a concentrated light image is thus obtained which is projected, at the front of the lighting module 10, by the lens 16, in a direction substantially parallel to the optical axis AA.
  • the support 20 comprises the cache surface 22, so that a portion of the light rays R2 emitted by the source 14 and which are not emitted exactly at the focus F1 and which would pass below the cutting edge 28, if there was no cache area 22, will be intercepted by the latter.
  • this reflective surface is reflective, the light rays R2 are reflected a second time forward, passing above the cutoff edge 28 and the focus F2, and will be refracted downwards by the lens 16.
  • the rays The light emitted next to the first focus F1 is thus emitted under the cut-off in the lighting beam.
  • This lighting module 10 makes it possible to make a clean cut with this LED, because it projects the image of the cutoff edge at the front 28.
  • the shape of the cutoff in the lighting beam is thus determined. by the profile of the cutting edge 28, in a projection on a vertical and transverse plane.
  • the cache surface can be made non-reflective. In this case, it absorbs the light rays that meet it. The light beam will be less intense.
  • the photoemissive element is placed on a substrate 15 carrying the electrodes of the LED.
  • This substrate is directly attached to the printed circuit board 80. It is also possible to use an LED whose light emitting element is directly in contact with the printed circuit.
  • the surface of the light emitting element 14 is flush with the plane containing the cover surface 22. This is facilitated by the fact that the bearing surface 61 is parallel to the cover surface 22. The bearing surface and the surface of the cache are horizontal in this figure. The depth of the withdrawal 60 is equal to the shortest distance d between the bearing surface 61 and the plane containing the surface 22 of the cover.
  • the adapter 70 is fixed to the support 20 by means of a screw 90 screwing into a hole of the adapter 70.

  • the modified adapter or other adapter is inserted in the opposite direction through the opening 13, so that it rests in contact with the bearing surface 61.
  • the configuration of the modified adapter or the new adapter is chosen according to the thickness of the printed circuit and the shortest distance between the underside of the LED and the illuminating surface of the light emitting element 14. Thus, this illuminating surface is found positioned in a plane including the first focus F1.

  • the second printed circuit 180 comprises two LEDs, not shown, fixed to the second printed circuit 180 at connection points 182 and 184.
  • the driving of these two LEDs requires more tracks and components.
  • the second printed circuit 180 is thus thicker than the first printed circuit 80. There is thus a difference ⁇ between the second printed circuit 180 and the first printed circuit 80.
  • a second adapter 170 is used to carry the second printed circuit 180.
  • This second adapter 170 is identical in shape to the first adapter 70, except that it has a smaller thickness than the first one. adapter.
  • This difference in thickness between the adapter is equal to the difference in thickness between the two printed circuits, and thus makes it possible to compensate for it so that these two types of LED assembly can be placed in the optical module 10, so that the illuminating surfaces of the photoemissive elements are in the vicinity of the first focus F1.
  • the second adapter 170 is therefore thinner by a difference ⁇ than the first adapter 70.
  • the positioning of the LEDs is such that the point The center of the illuminating surface for the first LED is positioned laterally and longitudinally on the adapter at the same level as the center point of the illuminating surface or all of the illuminating surfaces for the LED or LEDs of the second printed circuit.

These walls are perpendicular to these surfaces. As the recess also has walls perpendicular to the bearing surface 61, these walls will allow to wedge the adapter in the withdrawal and thus position it precisely. So, as we can see in figure 5 when the adapter slides along the bearing surface, during assembly, a transverse wall 72 of the adapter abuts with a transverse wall 62 of the recess 60. It is also possible to wedge a longitudinal wall 73 of the adapter against a longitudinal wall 63 of the withdrawal 60.

  • the ends of this wall 62 are closer to the rear of the reflector 12 that the middle 65 of this wall is, the latter being closer to the cutting edge. It is thus possible to bring the LED closer to the cutting edge, while maintaining a sufficient thickness of material between the ends of the cutting edge 28 and the ends of the wall 62.
