    [0001] The invention relates to a vehicle headlight and more particularly to a front headlight of an automobile vehicle without ice. FIG. 1 illustrates a schematic view in cross section along the Y axis of a front projector as disclosed in particular in the document EP2325883. The projector comprises a casing 14 of generally elliptical shape, the front face of which is sealed by a transparent wall 12, made of, for example, glass, or a transparent resin. Such a wall 12 is generally referred to as "ice". The housing 14 supports a pair of illumination modules 18 and 20 disposed within the housing 14 adjacent to the Y axis. One of the lightning modules 18 and 20 is a parabolic module. It comprises conventionally, a reflector 22, a light source 24 and a shield or shield 26. The reflector 22 has a parabolic shape and the light source 24 is of the halogen or other incandescent lamp type, or of the lamp type. discharge. The lamp 24 is fixed to the center of the reflector 22 and protrudes inside the reflector 22 through a hole in the center of the reflector 22. The inner surface of the parabola 22 is covered with a reflective surface for the light emitted by the lamp 24 so as to project the light beam generated by the lamp 24 towards the outside of the projector 10 at the front of the vehicle by passing through the window 12. The concealer 26 arranged in front of the lamp 24 prevents the rays The other optical module 20 comprises a support 21, a projection lens 25, a light source 27 and a radiator 28. The light source 27 comprises a light source 27 which is illuminated by the light source 27. or a plurality of light-emitting diodes (or LEDs) which are implanted on the front face of a substrate 29. The rear face of the substrate 29 is supported by the flat upper face of the radiator 28. The projection lens 25 is disposed above the LED 27 and is supported by the upper face of the support 21 itself supported at its base by the front face of the substrate 29 and / or the radiator 28.
    [0002] The LED 27 is able to generate a light beam along a predetermined light distribution plane, on the road, at the front of the vehicle. The ice 12 closing the housing 14, is traversed by the light beams. An adhesive seal 13 is disposed in a peripheral groove 15 formed in the peripheral edge of the casing 14 and serves as a water seal when the peripheral edge of the ice 12 is mounted in the groove 15. Such ice has many disadvantages, the main ones are mentioned below. It alters the lighting beam and lowers the lighting performance by around 10%. In certain climatic conditions, there is a condensation effect on the inner face of the ice, which further alters the lighting beam. The manufacture of ice cream involves a complex process that requires high investment in tools. Finally, on the aesthetic level, seen from the outside of the vehicle, the ice disturbs the vision of the technical elements present inside the projector (reflections on the ice); technical elements that have a stylistic impact and participate in the visual signature of the vehicle.
    [0003] The invention therefore aims to provide a projector, free of ice, which does not have the aforementioned disadvantages. It proposes for this purpose, a projector for a motor vehicle of the type comprising at least one light source of the type with one or more LEDs mounted on a support plate, a reflector able to reflect the light emitted by the light source, an arranged lens to receive the light beam reflected by the reflector, and a heat sink integral with the support plate, said projector being characterized in that it is free of ice and in that it comprises a housing supporting at least one lighting module having a shell supporting the reflector, the front face of the shell being shaped to receive the lens tightly; the hull and the plate supporting the light source are also sealingly connected to the heat sink. According to one characteristic, the inner face of the shell is shaped to define the reflector. According to another characteristic, the lighting module comprises a first sealing plane defined between the lens and the front face of the shell and a second sealing plane defined between the heat sink, the plate supporting the light source and the shell. The first and second sealing planes define bonding and / or joint interfaces for respectively, on the one hand, the lens with the front face of the shell and, on the other hand, the heat sink with the plate supporting the source of the light and the hull. According to one characteristic, the lighting module is retained in the housing of the projector by at least three fixing points of the ball joint type, at least two of which are able to adjust the light beam coming out of the projector through the lens.
    [0004] According to another characteristic, the first attachment point is fixed, the second is manually adjustable for the azimuth adjustment of the projector and the third is electrically adjustable to ensure the adjustment of the projector in location. According to another characteristic, the lighting module is fixed on the rear face of the housing by the first, second and third fixing points. According to one characteristic, the projector comprises a sealed electric motor whose output shaft is coupled to the third attachment point integral with the heat sink.
    [0005] According to another characteristic, it comprises at least two lighting modules, the electric motor being arranged between the two lighting modules and the output shaft of the electric motor being coupled to a beam comprising two arms extending symmetrically. on both sides of the output shaft of the electric motor; the free end of each arm being coupled to each third attachment point. Finally, according to another characteristic, it further comprises a signaling lighting device arranged on the edge of the upper face of the projector housing so as to create an underlining effect of the projector by analogy to a human eyebrow. Other features and advantages of the invention will become apparent upon examination of the following detailed description, and the accompanying drawings, in which: FIG. 1, already described, schematically illustrates an embodiment of a headlamp according to the state of the art by a top view in cross section in the direction Y; FIG. 2 schematically illustrates, according to a longitudinal view along the X axis, a headlight according to the invention arranged in the front part of a vehicle revealing a lighting module represented in cutaway; Figure 3 illustrates the projector according to the invention in a perspective view along the Y axis; FIG. 4 illustrates the lighting module of the headlight according to the invention, in perspective, and seen along the X axis; and FIG. 5 illustrates the illumination module of the headlamp according to the invention, in cutaway, along a longitudinal section along the axis X. In the various figures, the headlamp is located in space using the XYZ reference system, generally used by automotive designers, wherein the X direction is the longitudinal direction of the vehicle (which is substantially parallel to the lateral sides of the vehicle), the Y direction is the transverse direction of the vehicle (which is substantially perpendicular to the lateral sides), and the direction Z is the vertical direction of the vehicle (which is substantially perpendicular to the longitudinal X and transverse Y directions). In the description which follows, the orientation indications such as "upper", "lower", "up", "down", "above", "below", "left", "right", "vertical", "horizontal", "transverse", "longitudinal", "forward", "rear",. correspond to those of a motor vehicle in the assembled state. In the figures, the same elements are identified by the same references. Figures 2 to 5 illustrate an embodiment of a left front projector 100 having a housing 101 supporting two adjacent lighting modules 110 providing the high beam and crossing (or code) lighting functions. The signaling lighting: direction change indicator (or flashing) and daytime running lights (DRL), is made from a light guide 300 extending above the projector 100 in the manner of an eyebrow by analogy to the human eye. Each lighting module 110 is fixed on the vertical rear face 102 of the housing 101 which "open" downwards in the sense that it lacks a horizontal bottom. The vertical rear face 102 is staggered in the X and Y directions and each lighting module 110 and fixed on a vertical part 103, 104 of the rear face 102 being offset with respect to one another in X and Y. The upper face 105 of the housing 101 covers the two lighting modules 110. The housing 101 is arranged inside a cavity 200 formed between the front part of the engine hood 210 and the front bumper 220 of the vehicle.
    [0006] It is fixed on a part of the bodywork like any projector. The rear face 102 is accessible from inside the vehicle to allow adjustment of the lighting modules 110. The upper face of the housing cooperates with the engine cover. The projector 100 is devoid of ice which usually closes, in a sealed manner, the front face of the housing comprising the lighting modules. Each lighting module 110 comprises a light source which, in the embodiment described, comprises two LEDs 111, 112 (only the LED 112 is visible in FIGS. 4 and 5) mounted adjacent on the same plane substrate 113 defining a plate supporting the two LEDs 111 and 112. It comprises a "double" reflector 114 able to reflect the light emitted by the two LEDs 111 and 112. They are separated from each other by a central partition 115 separating the reflector 114 in two identical parts. A shell 116 covers the plate / substrate 113 supporting the LEDs 111 and 112. Advantageously, a portion 117 of the inner face of the shell 116, of generally hemispherical general shape, is shaped to define the double reflector 114. The inner face 117 is lined with a reflective layer, for example metallized, made either in the mass with the shell 116 is attached to the inner face 117 of the shell 116. A lens 118 overmolded plastic is sealingly attached to the open front face 119 of the shell 116 so as to receive the entire light beam reflected by the reflector 114. Preferably, the plastic is a polycarbonate covered with a protective varnish as usually used for a projector glass. The lens is a piece injected in several times given its very large thickness in places.
    [0007] An additional injection of a black polycarbonate is also provided to achieve the interface of the lens 118 with the shell 116. The lens 118, in a known manner, comprises a flat rear face and a convex front face. The lens 118 is mounted on a housing 120 by gluing its flat surface. The housing 120 supporting the lens 118 is attached and fixed, for example by screws, on the front face 119 of the shell 116. A heat sink 121, of fin type radiator in the embodiment described, is reported and fixed under the support plate / substrate 113 and the base 122 of the shell 116. The base 122 of the shell 116 is attached to the face of the plate 113 supporting the LEDs 111 and 112, and fixed at the same time as the plate 113 on the dissipator 121 , by means of screws for example. The front portion 123 of the base 122 of the shell 116 defines a step 125 whose upper edge 124 bears on the plate 113 and the thickness of the step 125 is clamped between the dissipator 121 and the housing 120 supporting the lens 118. The thickness of the step 125 thus serves as an interface for fixing the housing 120 on the shell 116. The watertightness of the lighting module 110 is made on two planes PH and PV. A first PV vertical sealing plane (in YZ) is defined between the rear face of the housing 120 and the front face 119 of the shell 116. A second horizontal sealing plane PH (in XY) is defined between the heat sink 121 , and the plate 113 supporting the light source and the base 122 of the shell 116. The first and second sealing plane PH and PV define bonding interfaces and / or seal. The glue (or seal), used for the PH sealing plane, is a thermal conductive material that guarantees watertightness.
    [0008] There is not necessarily a need for heat conduction of the seal, because the heat source (LED) is directly related to the radiator which is for example aluminum. Different materials can be used for the seal, depending on the continuous operating temperatures: nitrile (100 ° C), hydrogenated nitrile (125 ° C), ethylene propylene (125C), fluorocarbon (200 ° C).
    [0009] Otherwise, a glue silicone glue type may be suitable, if we consider that the modules are unmountable. The glue (or seal) used for the sealing plane PH is a material that guarantees watertightness. The lighting module 110 is fixed on the rear face 102 of the housing 101 by three attachment points 126, 127 and 128 respectively defining three links of the ball-and-socket type. The three links 126, 127 and 128 between the rear face 102 of the housing 101 and the lighting module 110 are distributed as follows: The first and second links 126 and 127 are arranged at the rear of the lighting module 110 in the upper part of the shell 116 respectively in the vicinity of the left and right lateral edges 129 of the module 100. The left and right lateral edges 130 129 define vertical wings extending parallel to each other in the direction X. They end, aesthetically speaking, the external appearance of the lighting modules 110 while protecting the fixing means and / or adjustment of the modules 110. One of the first or second links 126, 127 is fixed and the other is manually adjustable to ensure the azimuth adjustment of the module.
    [0010] The third link 128 is arranged under the lighting module 110. It is electrically adjustable to provide adjustment in site of the module (plate). The electrical adjustment is provided by means of an electric stepper motor 129 arranged and fixed between the two lighting modules 110 on a fastening tab 130 coming from the rear face 102 of the housing 101 and projecting from the front The output shaft 131 of the motor 130 is mechanically coupled to the third link of each lighting module 110 by means of a spreader 132.
    [0011] In the embodiment described, the dissipator 121 is disposed under the support plate 113 and the third link 128 has a tab 133 integral with the heat sink 121 and protruding under the heat sink 121. The tab 133 is disposed under the dissipator 121 between the first and second links 126 and 127. The free end of the tab 133 is shaped to receive the free end of a 134 of the two arms 134 and 135 of the spreader 132 which extend symmetrically from each other. other of the output shaft 131 of the electric motor 129; the free ends of each arm 134 and 135 cooperating respectively with the free ends of the tabs 133 of the third links 128 by a ball joint.
    [0012] Thus, the electric motor 129 ensures the simultaneous adjustment of the two lighting modules 110 by means of the lifter 132. Due to its open arrangement (no front or bottom), the housing 101 of the projector 100 promotes the circulation of the air flow entering the interior of the projector 100 when the vehicle rolls.
    [0013] The air flow enters the cavity 200 in which the projector 100 is housed, between the engine bonnet 210 and the front bumper 220, then it is evacuated from the rear of the housing 101 of the projector 100 downwards by sliding along of the wall defined by the rear face 102 of the housing 101. The advantages of an ice-free projector according to the invention, therefore "open" towards the outside and the inside of the vehicle, with sealed lighting modules, are numerous. The condensation effects that existed on the inner wall of the ice are removed.
    [0014] On the other hand, the airflow entering the housing of the projector participates in the cooling of the light sources because the radiators are in the open air, and no longer locked in a closed box. The design of the lighting modules seen from outside the vehicle is no longer disturbed by the ice and its reflections (stylistic impact). The optical disturbance of the ice causing a loss of about 10% of the luminous flux is suppressed. Elimination of the cost of ice making equipment. Decrease in the manufacturing cost of the projector because there is less ice and the case is simpler and smaller. Reduce the cost of repairing the projector in the event of a low-speed accident because replacing only the damaged parts. Indeed, the lighting modules and the fixing and adjustment systems are no longer locked in a glued box, and are thus easily accessible.
    [0015] Decrease in the mass of the projector: less ice mass, and half the body weight less. Contribution to the overall decrease of the mass of the vehicle. Decrease of the environmental footprint of the projector with the least use of plastic: ice and half box less.20
