  • the heat sink 10 for optical module 1 for a motor vehicle V according to the invention is described with reference to Figures 1 to 6 .
  • motor vehicle is meant any type of motor vehicle.
  • the optical module 1 (described below) illustrated in the figure 1 includes the heat sink 10 and is integrated in a lighting device 3.
  • the lighting device 3 is a projector.
  • the motor vehicle V comprises a right headlight and a left headlight.
  • the heat sink 10 according to the invention is described in detail below with reference to figures 2 to 6 .
  • the edge A1 is common to the central part 101 and to a lateral part 102, the edge A2 is common to the central part 101 and to the other lateral part 102.
  • the angle ⁇ is represented on the figure 3 which represents the unfolded heat sink 10. In a nonlimiting embodiment, said angle ⁇ is between 0 ° and 180 °. In a nonlimiting variant, said angle ⁇ is equal to 90 °. Such an angle is easy to obtain when the plate 100 is folded.
  • the plate 100 is composed of a thermally conductive material. Material allows heat to escape produced by the light sources 13 and the printed circuit board 11 (described below). The material is such that it can be transformed by a manufacturing process which includes cutting, folding, and punching and in a non-limiting embodiment stamping.
  • the thermally conductive material is metallic. In a non-limiting embodiment of this variant, the material is aluminum.
  • This material provides good thermal conductivity, in a nonlimiting example from 120 watts per meter-kelvin (W ⁇ m -1 ⁇ K -1 ), unlike a molded heat sink with dissipation fins which does not allow to obtain a thermal conductivity of only 90-120 W ⁇ m -1 ⁇ K -1 .
  • the light sources 13 are thus well cooled and their efficiency is therefore not degraded due to the heat.
  • aluminum is a light and easy-to-shape material. It is thus possible to obtain up to 40% reduction in the weight of the heat sink 10 compared to a molded heat sink.
  • the material is copper or brass. These materials still have better thermal conductivity than aluminum but have a higher cost and a higher weight.
  • the heat sink 10 makes it possible to receive at least one light source 13 and an optical surface 12, the assembly 10, 13 and 12 forming an optical module 1.
  • the light source 13 is either mounted directly on the heat sink 10 (assembly called in English “submount”), or mounted on the heat sink 10 by means of a printed circuit board 11.
  • the heat sink 10 is adapted to receive said printed circuit board 11 on which said light source is arranged 13.
  • the optical module 1 is composed of elements 10, 11, 12 and 13.
  • the optical surface 12 is a reflector. In another nonlimiting embodiment, the optical surface 12 is a lens. Thus, an optical surface 12 is the surface responsible for reflecting the individual light beam emitted by the light source (s) 13. In the following description, the reflector is taken as a non-limiting example.
  • the heat sink 10 further comprises an adjustment device 110 of the optical module 1 on a housing 2 of the projector 3.
  • the adjustment device 110 cooperates with a fixing system 210.
  • the printed circuit board 11, said at least one light source 13 and the reflector 12 are fixed to the heat sink 10 in the following manner.
  • the heat sink 10 further comprises centering means 130 of a reflector 12 of the optical module 1.
  • These centering means 130 are arranged at one end of the central part 101 of the plate 100 and form two rounded notches. They thus make it possible to center the reflector 12 on the heat sink 10 but also the printed circuit board 11.
  • the light source or sources 13 placed on the printed circuit board 11 are thus centered relative to the reflector 12.
  • the reflector 12 comprises two positioning pins 123 (illustrated on the figure 1 ) which thus fits into the two rounded notches 130.
  • said heat sink 10 further comprises fixing lugs 140 of a reflector 12 of the optical module 1 arranged on either side of the central part 101.
  • the fixing lugs 140 comprise two orifices 141 and are thus adapted to receive two fixing screws 240 (illustrated in the figure 4 ) which are inserted in the two orifices 141.
  • the reflector 12 comprises two hollow threaded fixing cylinders 124 (illustrated in the figure 1 ) into which the fixing screws 240 are screwed. It will be noted that the fact of dissociating by different means the centering and the fixing of the reflector 12 on the heat sink 10 makes it possible to obtain at the mechanical level a robust fixing unlike fixing means which would also serve as centering.
  • said heat sink 10 further comprises centering holes 150 of the printed circuit board 11 disposed on the central part 101.
  • These centering holes 150 are of the poka type yoke. These are polarizing devices which make it possible to correctly position the printed circuit board 11 on the heat sink 10.
  • the figure 5 illustrates the heat sink 10 with the printed circuit board 11. It will be noted that the latter has centering holes 115 corresponding to the centering holes 150 of the heat sink 10. They are arranged opposite said centering holes 150 when the circuit board printed 11 is well positioned on the heat sink 10. The centering holes 115 and 150 are adapted to receive a centering pin (not shown) from the reflector 12. The reflector 12 is thus also correctly centered on the printed circuit board 11. The printed circuit board 10 is thus sandwiched between the heat sink 10 and the reflector 12 and can therefore no longer move due to these centering pins which cooperate with the centering orifices 115 and 150, but also due to the fixing of the reflector 12 on the heat sink 10 by means of the two fixing lugs 140.
  • the printed circuit board 11 also comprises a connector 230 connected to a control and supply unit (not illustrated) for the light sources 13.
  • said heat sink 10 further comprises at least one support tongue 120 of a reflector 12 of the optical module 1.
  • the heat sink 10 comprises two support tabs 120.
  • the support tongue 120 is arranged at one end of the central part 101.
  • the two support tongues 120 are arranged on the end opposite to that on which the centering notches 130.
  • a support tongue 120 has an L shape. It will be noted that the support tongue (s) 120 also have a polarizing function. Thus, each support tab can have a different slope for its L-shape, depending on the reflector 12 that the heat sink 10 must receive.
  • each light beam produced by an optical module 1 will be well positioned relative to to the other adjacent light beams of the adjacent optical modules so as to obtain a global light beam adapted to the photometric function f1 sought.
  • the reflector 12 has for this purpose a rib (not shown) cooperating with each support tongue 120.
  • the invention also relates to an optical module 1 for a motor vehicle V.
  • the optical module 1 is part of a lighting device 3 for a motor vehicle V, the lighting device 3 comprising a housing 2 and at least one module optics 1 described above.

  • the projector 3 comprises six optical modules 1.
  • the optical surface 12 shown in the nonlimiting example is a reflector.
  • said optical module 1 comprises a single light source 13 and a single reflector 12.
  • a single light source 13 is disposed on the heat sink 10 (either directly or indirectly via the printed circuit board 11) and cooperates with the reflector 12 associated with the heat sink 10.
  • the optical module 1 also comprises a printed circuit board 11 adapted to be mounted on the heat sink 10 and to receive said at least one light source 13.
  • the printed circuit board 11 is glued to the plate 100 or screwed to the plate 100 of the heat sink 10.
  • One or more light sources 13 is connected to a printed circuit board 11, also called a PCB (“Printed Circuit Board” in English).
  • the light sources 13 are arranged on the printed circuit board 11.
  • the light sources 13 are fixed directly to the heat sink 10. Note that we can also have a combination of these two modes.
  • the light sources 14 are semiconductor emitting chips.
  • a semiconductor emitting chip is part of a light emitting diode.
  • light-emitting diode is meant any type of light-emitting diode, whether in non-limiting examples of LEDs (“Light Emitting Diode”), OLEDs (“organic LEDs”), AMOLEDs (Active-Matrix-Organic LEDs), or FOLED (Flexible OLED).
  • the light beam is cut off.
  • the photometric function is a so-called “low beam” function for producing a low beam.
  • the light beam is cut off. It has two segments, one of which is horizontal and the other inclined. According to the regulations in force, the inclined segment forms an angle of 15 ° with respect to the horizontal segment.
  • three optical modules 1 will be used to make the segment inclined by 15 °, namely to make a sub-function called "kink” in English, and the other three optical modules 1 will be used to realize the horizontal segment, that is to realize a sub-function called "flat” in English.
  • the individual light beams produced by the light source (s) of each of the first three optical modules 1 will be aligned with one another (by adjusting the optical modules 1 by means of the adjustment device 110 as described above) of so as to produce the 15 ° inclined segment.
  • the individual light beams produced by the light source (s) of each of the last three optical modules 1 will be aligned with one another (by adjusting the optical modules 1 by means of the adjustment device 110 as described above) of so as to produce the horizontal segment.
