Definitions

  • the invention relates to an optical module for a vehicle headlamp.
  • such an optical module operates with a light source having the drawback of emitting heat. It is therefore equipped with a radiator allowing this heat to be absorbed, so as to maintain the temperature of said module at a relatively low level. In this way, the operation of the optical module is not affected by too high a temperature.
  • This type of module has already been the subject of patents.
  • This module includes a radiator capable of blowing cooled air towards the light source.
  • EP2679883A2 discloses a projector in which a fan is mounted opposite a radiator.
  • the fan is mounted on a cover mounted in an opening in the projector housing or screwed onto a radiator.
  • An optical module according to the invention implements a fan / radiator assembly, which is easy and quick to assemble and disassemble, which is compact and is of reduced cost.
  • the subject of the invention is an optical module for a vehicle headlamp, said optical module comprising a radiator provided with one or more heat dissipating surfaces, a fan capable of sending air onto the said at least one heat dissipating surface, and a light source supported by said radiator.
  • the main characteristic of an optical module according to the invention is that the fan is fixed to the radiator by clipping. In this way, fixing the fan to the radiator is easy and quick, because it requires neither specific tools nor complicated handling requiring precision and rigor.
  • the fan can be detached from the radiator at any time as simply and quickly as during installation on said radiator.
  • the fan is oriented relative to the radiator, so that the air pulsed by said fan passes between the heat dissipating surfaces of the radiator. It is advantageously assumed that the heat dissipating surfaces of the radiator are made of metal.
  • the radiator can support the light source, either directly or indirectly by means of a holding piece. Each heat dissipating surface can, for example, be represented by a fin or a pin.
  • the radiator comprises a box having one or more edges and at least two deformable clipping tabs projecting from the edge or at least two of said edges, the fan being placed on said radiator between said at least two clipping tabs.
  • the fixing of the fan to the radiator comprises a first phase during which the bringing together of the fan towards the radiator will cause an elastic spacing of the clipping lugs, then a second phase during which the clipping lugs will close on said fan once it has reached its final position of attachment to said radiator.
  • the legs close on the ventilator in a natural way while trying to find their position of relaxation. It is assumed that all the clipping tabs project from said edges in the same direction.
  • the fan is fixed by the top of the radiator.
  • the case has two clipping tabs projecting from two opposite edges opposite one another. This is a simple configuration ensuring a homogeneous and efficient stowage of the fan on the radiator.
  • each clipping lug has three segments and two elbows, the distance separating said lugs being less than the dimensions of the fan so that the fixing of the fan to said radiator is effected by means of a spacing of said lugs.
  • the two legs are inclined relative to each other so as to promote the insertion of the fan.
  • the two legs are oriented relative to each other so as to form a bottleneck gradually narrowing as one approaches the radiator, thus facilitating the pre-positioning of the fan. relative to the radiator, and then guiding its translation to bring it closer to said radiator.
  • each edge is surmounted by at least one positioning element of the fan projecting from the housing in the same direction as that of the clipping tabs.
  • each positioning element is constituted by a flat wall extending in the same plane each edge of the radiator housing.
  • the radiator has several dissipative surfaces formed by parallel fins.
  • the fins all have the same dimension and are rigorously aligned.
  • Each of the fins can advantageously be materialized by a metal sheet.
  • the fins are separated from each other. In this way, they constitute a discontinuous network, two successive fins being separate and independent from each other.
  • the fins are in continuity with one another to form a single piece.
  • two successive fins are connected to each other by a 180 ° bend.
  • the fins constitute a single piece that can easily be manipulated to, for example, be inserted in the radiator housing and then be fixed therein.
  • the fins are made of aluminum.
  • the fins being put in the form of sheets can thus be formed with 99% pure aluminum, unlike existing radiators made from an injected aluminum alloy, less efficient in terms of cooling.
  • the light source comprises at least one light-emitting diode.
  • a light-emitting diode constitutes an efficient light source in terms of light intensity produced, while remaining compact.
  • the fan is fixed to the radiator by means of a sliding of said fan along said radiator and then of a clipping by clipping.
  • a light module according to the invention for which the fan is fixed laterally on the radiator.
  • the sliding takes place by means of an interaction between two grooves and two rails, said two grooves belonging to one of the two elements constituted by the radiator and the fan, and said two rails belonging to the other. element.
  • the two rails belong to the fan, then the grooves belong to the radiator, and vice versa.
  • the grooves are introduced into the rails and slide along them until the fan has reached its final fixing position.
  • the second object of the invention is a vehicle headlamp comprising at least one optical module according to the invention.
  • a light module according to the invention is particularly suitable for use in a vehicle headlight, and more particularly in a motor vehicle headlight.
  • An optical module according to the invention has the advantage of being flexible to use and to maintain, because the fan can be fixed to the radiator in a simple and rapid manner, and can be removed at any time in an equally easy manner. . It also has the advantage of being efficient in terms of temperature regulation, insofar as the radiator is made of folded sheet, with pure aluminum having good thermal conduction.
  • an optical module 1 constitutes an elongated element, and schematically comprises two light-emitting diodes 2, 3, two reflecting surfaces 4, 5, an output diopter 6 and a cooling device having a fan 7 and a radiator 8.
  • the two diodes 2, 3 are placed on a flat support piece 9 of small thickness, secured to the radiator 8. More precisely, this support piece 9 has two flat surfaces 10, 11 and parallel, a diode 2, 3 being fixed on each said surfaces 10, 11.
  • Each reflecting diopter 4, 5 is curved and is located opposite a diode 2, 3 so as to reflect the light beams coming from said diode 2, 3 towards the output diopter 6.
  • the device for cooling is placed behind the diodes 2, 3 relative to the output diopter 6. In other words, the diodes 2, 3 are placed between the output diopter 6 and the assembly formed by the fan 7 and the radiator 8.

  • each tab 19, 20 extends in a direction which is opposite to that where the bottom 18 is located.
  • the first segment 21 extends in the same plane the wall 14, 15 from which it emerges, the second segment 22 extends said first segment 21, and tends to extend towards the center of the housing 13.
  • the third segment 23 extends said second segment 22 while being slightly inclined relative to the first segment 21 and tends to extend towards the outside of said housing 12, the two elbows being located between said three segments 21, 22, 23.
  • the third segments 23 of the two legs 19, 20 facing each other, define between them a space which is gradually reduced as it approaches the bottom 18 of the housing 12.
  • Two positioning legs 24, 25, 2 6, 27 surround each of the two clipping lugs 19, 20, each of said positioning lugs 24, 25, 26, 27 being constituted by a flat wall of small thickness, extending in the same plane the side wall 14, 15 of the housing 12 from which it emerges, and projecting in the same direction as that of the clipping tab 19, 20.

  • the fins 13 of the radiator 8 all have the same length and are arranged in said radiator 8 while being parallel to each other. They are further aligned with each other, two successive fins 13 being connected to each other by means of a segment 31 bent at 180 °. In other words, each fin 13 is extended at its ends by bent segments 31 in opposite directions.
  • the fins 13 being machined in sheets can be made with 99% pure aluminum, thereby ensuring efficient thermal conduction, in particular for cooling the optical module 1.
