Definitions

  • the invention relates to a lighting device for a motor vehicle according to the preamble of claim 1.
  • the dynamic pressure in front of the vehicle is used during a journey to produce a cross-flow to a defogging of the illumination device.
  • This is particularly advantageous since lower pressure differences form in the vehicle or engine compartment interior due to the increased closing of joints in the region of the vehicle front, which pressure differences can be used to generate a transverse flow within a motor vehicle headlight.
  • the pressure differences between the vehicle interior and vehicle exterior can be used advantageously during a journey. Due to the increased cross-flow, a correspondingly better defrosting of the illumination device takes place, which leads to fewer complaints by the end customer, who can classify a thin film of water on an inner side of a headlight as a defect of the headlight.
  • the ventilation connection is formed as part of a housing of the lighting device and molded, for example, to the housing. Thus, no additional part must be kept in the assembly of the lighting device.
  • FIG. 1 shows a schematic cross section through a lighting device 2 for a motor vehicle.
  • the lighting device 2 comprises a housing 4, a cover 6 and at least one light module 8.
  • the light module 8 is adapted to transmit a light 10 through the cover 6 in the direction of an exterior of the motor vehicle and to generate a light distribution outside the motor vehicle.
  • An inner space 12 of the lighting device 2 is in contact with an outer space of the lighting device 2 via an initial ventilation connection 14 and a second ventilation connection 16 for an air exchange.
  • lighting device 2 is exemplified as a headlight.
  • an air inlet via the ventilation connection 14 takes place. Air enters the interior 12 via the ventilation connection 14 at a ventilation inlet 18. At a vent outlet, air exits the interior 12 and enters the vent 16.
  • the opening 50 extends transversely or orthogonally to the plane of the slit. This slot-shaped design of the opening 50 extends at least in sections along the edge 32. Of course, the slot-shaped expression of the opening 50 also on side edges or along the edge 26 and only partially extend.
  • the opening 50 is funnel-shaped in cross-section, which means that in the air inlet direction to the ventilation inlet 18, the inner diameter of the ventilation connection 14 tapers.
  • the vent connection 14 has in a form not shown in the course of the opening 50 to the ventilation inlet 18 on a drainage opening through which, for example, in the opening 50 entering water and / or dirt can be removed.
  • This drainage opening for the removal of water and / or dirt can advantageously dissipate the water, wherein the back pressure is still sufficient to supply sufficient air to the ventilation inlet 18.
