Definitions

  • the present invention relates to a radiation concealment device light for a motor vehicle headlight.
  • Devices occulting light radiation for projector of motor vehicle are well known and widely spread. Their function is to avoid that the light emitted by the filament of a projector lamp is not diffused directly outward through the projector closing glass. In other words, he is to limit the emission of light so that it meets only the background and side parts of the mirror that equips the projector, before being returned, after reflection, through the ice.
  • Such an occluder generally has a shape that allows him to style the front of the lamp, and has a front or front face that prevents any direct broadcast from the light to the projector's mirror. It also has side parts which the edges have indentations of such shape that the light can not be emitted only towards the useful part of the mirror.
  • a concealment device according to the preamble of claim 1 is known from DE-A-19508 472.
  • Document FR-A-2 343 966 describes a radiation shield. This one covers only the front and bottom parts of the lamp. Slots in part lower are provided to allow cooling of the lamp. These slots are sufficient to properly fulfill their function of cooling the lamp. The heat released by it can also be evacuated by the large space left free by the mask.
  • the present invention aims to overcome this drawback by means of simple and inexpensive ways.
  • the occulting device which comprises an element shading device capable of covering the front portion of the projector lamp which includes a front, as well as lower, upper and lateral parts and an opening for the engagement of said lamp, and which comprises fixing means on a mirror of the headlamp, is characterized by the fact that at least one of the parts side has at least one ventilation window protruding out of said element and leading to outside to the top.
  • This window facilitates the natural convection of the warm air released by the lamp.
  • the invention also relates to a motor vehicle headlight equipped with a concealment device according to the present invention.
  • the fixing means on a mirror of the projector can be constituted by at least one sheet flange on which teeth are formed hooking.
  • the occulting device shown in the accompanying figures is made of folded metal sheet. It consists mainly of a concealment element 2 and an element 3 attachment to the upper cheek of the mirror of a motor vehicle headlight.
  • element 2 is substantially in a truncated pyramid, that is to say that its upper walls 20, lower 21 and 22 and 23 are divergent from a flat front wall 24.
  • the entire device, except the wall 24, is preferably formed by folding of a single piece of sheet metal, including the attachment element 3, which will be described further in the description.
  • the front edge of the lateral faces 22 and 23, disposed on the left side of FIG. 1 shows a small ear 240, bent at 90 ° to allow the setting place, guiding and retaining the bottom wall 24, formed separately.
  • the opposite edge of the side faces has a wide notch 220 whose profile is determined to let light from a lamp and orient it only towards the mirror of the projector.
  • the lateral faces 22 and 23 each have two ventilation windows.
  • a first window 6 is arranged in the lower part of each of the walls. It is formed by cutting the sheet in a horizontal line and repoussage the material outwardly so that it protrudes out of the element 2.
  • this window which extends horizontally, opens towards the outside in the direction of the upper part of the concealment element 2.
  • the window 5 is formed in the same way as the window 6 but is in overturned in relation to it, so that its opening protrudes towards the outside is oriented towards the lower part of the occulting element.
  • the underside referenced 21 of the occulting element is also provided with two windows 7 formed in the same way as the windows 5 and 6, extending transversely, and whose opening is directed towards the rear part of the occulting element.
  • the attachment element 3 is formed of a vertical part 30 which continues upwards by means of attachment 4 which extend in one direction generally horizontal.
  • these attachment means comprise a part in general form of "U” whose horizontal base is referenced 41 and the wings are referenced 42. These wings 42 are folded 90 ° outwards to form a flange 43, some parts of which are cut and folded to form gripping teeth 44.
  • FIG. 5 shows diagrammatically the manner in which the concealment element according to the invention fits into a motor vehicle headlamp bearing reference numeral 8.
  • the general outline of the housing B of this headlight is shown in dotted lines. , while its ice G is represented by a dashed line.
  • the mirror of the projector is referenced M while its lamp is referenced L.
  • the concealment device according to the invention is fixed by its element 3 to the upper cheek of the mirror M , so that the concealment element 2 caps the front part of the lamp L.
  • the start of the lamp L will generate a luminous flux and cause a release of heat. This will of course cause heating of the occulting device.
  • the fact that the occulting device has, on one of its lateral faces, at least one window which makes protruding out of the occulting element and opening outwards towards its the upper part will facilitate the evacuation of heat upwards by an effect of natural convection.
  • the shape of the windows is determined not to let the slightest light radiation.
  • the occulting device presents two windows on each of its side and bottom faces.
  • he could have a different number, for example one or three, and in one embodiment non-limiting, only on one or both of its side faces.
  • the device of the invention makes it possible to significantly increase the duration of use of the lamp while preserving the shield itself and other parts neighboring areas which would otherwise be deformed or deteriorated by temperature generated by the lamp.
