  • This lighting module can be mounted in a motor vehicle headlight.
  • this module produces a cut-off lighting beam such as for a lighting function of the “code” type or alternatively low beam.
  • the lighting module 2 shown in figure 1 essentially comprises a radiator, or heat sink, 6 on which is arranged a plate 16 provided with one or more light sources 12, preferably of the light-emitting diode type.

  • the light source is located at the first focal point and a reflecting surface 14 is located substantially in the plane of the light source and with a leading edge located at the second focal point.
  • the reflective surface 14 is commonly referred to as a "bender" since it reflects a portion of the rays from the reflective surface 10 to an upper portion of the lens. Indeed, in the absence of the reflecting surface 14, the rays passing to the rear of the second focal point would meet the lens at a lower part with a lower angle of incidence than those passing through the second focal point. These rays would then be deflected by the lens so as to form the upper part of the lighting beam. The fact of returning these rays towards an upper part of the lens makes it possible to reverse this effect and to form the lower part of the beam. The front edge of the folder 14 thus forms a horizontal cut in the beam.
  • the reflecting surface of the folder 14 forms a projection in its middle so as to form two cut-off levels. different between the left part and the right part of the light beam, in accordance with the vehicle lighting regulations in force in most countries.

  • the figure 2 illustrates the radiator 6 of the module of the figure 1 , the radiator being equipped only with the folding machine 14 and the plate 16. It can be observed that the radiator 6 comprises a rear portion 6 1 supporting the plate and a front portion 6 2 . The front portion 6 2 is at a lower level than that of the rear portion 6 1 .
  • the profile of the radiator 6 is similar to that of a staircase, the front portion 6 2 corresponding to a first step and the rear portion 6 1 forming a second step, greater than the first.
  • the folder 14 is located essentially at the level of the front edge of the rear portion 6 1 . More precisely, the folder 14 comprises a central reflecting portion 14 1 and two lateral portions 14 2 in the form of an arm for fixing to the support 4 ( figure 1 ). This fixation will be further detailed in relation to the figure 6 .
  • the folder 14 thus has a U-shaped transverse profile where only the central portion 14 1 is optically active.
  • the folder can be made from a portion of sheet metal, by shaping, folding and cutting.
  • the front portion 6 2 comprises on its upper surface two bosses 6 3 . These bosses are intended to ensure an exact positioning in the vertical direction of the support 4, as will be detailed in relation to the figures 3 and 4 . These bosses can be more numerous. It could also be one or more bosses extending transversely, in the manner of a rib.
  • the front portion 6 2 also comprises, at its front edge, two lugs 6 4 for fixing the lens 8 ( figure 1 ), as will be detailed in relation to the figures 3 and 4 .

  • the lens 8 comprises two fixing lugs 8 1 extending from a lower edge towards the lugs 6 4 of the radiator 6. More precisely, these lugs 8 1 extend through openings 24 in the front portion 4 3 of the support 4. These tabs 8 1 may comprise cavities, or through passages, fitting the ends of the tabs 6 4 .

It is indeed important that the folder 14, more particularly its central reflective portion 14 1 , is parallel to the upper surface of the rear portion 6 1 of the radiator 6. In fact , any misalignment of the reflecting surface of the folder 14 is liable to significantly modify the photometry of the light beam of the module. It is therefore important to be able to position the folder 14 precisely not only in translation in the longitudinal direction but also vertically and in rotation about a transverse axis.
