- the housing 16 has two ventilation openings, one in the installed position of the lighting device on the vehicle Ventilation opening 30 is arranged in an upper region of the housing 16 and the other ventilation opening 32 in a lower region of the housing 16.
- the ventilation opening 30 is formed in a wall 34 of the housing 16 and is preferably arranged close to the disk 18 closing the light exit opening.
- the ventilation opening 30 is approximately rectangular in cross-section as shown in FIG. 4, but can also have any other cross-sectional shape.
- the ventilation opening 30 is covered with a mat-like insert 36 which is air-permeable and water-repellent.
- the insert 36 consists of a fabric, the individual fibers 37 of which are woven together in a stitch-like manner.
- the fibers 37 can for example be synthetic fibers and consist of polyester or other plastic.
- the insert 36 has, for example, a thickness of approximately 0.1 mm to several millimeters, in particular a thickness of approximately 0.5 mm.
- the density and the fine porosity of the insert 36 is determined such that the insert 36 on the one hand has a sufficient filter effect so that the entry of dirt and dust into the interior 10 is prevented or at least reduced, and that the insert 36 on the other hand has sufficient air permeability for Has ventilation of the interior 10.
- its fibers 37 can be impregnated with water-repellent, for example.
- the shielding device 40 is designed such that it has a channel-like section 42 covering the insert 36 which laterally protrudes beyond the insert.
- the section 42 is, for example, approximately triangular in cross section, as shown in FIG. 3, it has a side wall 43 which is arranged approximately at right angles to the insert 36 to the side of the insert 36 and this has a top wall 44 which is arranged inclined to the insert 36.
- the section 42 can also have a different, for example approximately rectangular or trapezoidal, cross-sectional shape.
- the section 42 is formed open on its two shorter sides, so that its channel shape results.
- the shielding device 40 can be fastened to the wall 34 of the housing 16 and, as shown in FIGS. 2 and 3, has a circumferential frame 46 projecting inwards from the side wall 43 or the top wall 44 toward the wall 34.
- the insert 36 is placed on the frame 46 from the side of the shielding device 40 facing the housing 16.
- the insert 36 can be glued to the frame 46 to fix it, wherein the insert 36 or the frame 46 can be designed to be self-adhesive for this purpose by means of a corresponding coating or an adhesive tape. However, adhesive can also be applied separately.
- the insert 36 can also be clamped in by an edge 48 of the shielding device 40 surrounding the frame 46 in order to fix it.
- the insert 36 then forms a pre-assembled unit with the shielding device 40, which is attached to the housing 16.
- the shielding device 40 is preferably made of plastic and is produced by injection molding.
- the shielding device 40 can be fastened to the wall 34, for example, as shown in FIG. 3 by means of a snap-in connection.
- a collar 50 surrounding the ventilation opening 30 may protrude outwards, in the outer circumference of which a plurality Recesses 52 or a circumferential depression are formed.
- the shielding device 40 can have a plurality of latching hooks 54 distributed over its circumference, which are arranged surrounding the collar 50 and which can be latched into the recesses 52 with corresponding latching projections.
- the insert 36 is clamped in the end position of the shielding device 40 on the housing 16 between the end face of the collar 50 and the frame 46.
- the shielding device 40 can also be attached to the wall 34 in another way, for example by gluing or screwing.
- the wall 34 of the housing 16, in which the ventilation opening 30 is formed is preferably arranged, as shown in FIG. 1, in such a way that, in the installed position of the lighting device on the vehicle, it faces downward with its outside.
- the wall 34 is arranged inclined with respect to a vertical 56 and has the outside facing downward. It is hereby achieved that no water from above can meet the insert 36 covering the ventilation opening 30 and can collect on it, but can instead run downwards from it. Due to its arrangement on the downward-facing wall 34, water running off the top of the lighting device does not flow via the insert 36 but drips off on the edge present between the top of the lighting device and the wall 34.
- the shielding device 40 is arranged in such a way that its open end faces point upwards and downwards, so that there is a continuous channel with the inclination of the wall 34. Possibly in the
- Shielding device 40 penetrating water then runs off in the channel formed by the side walls 43 and the top wall 44 without reaching the insert 36.
- 5 shows the insert 36 according to a second exemplary embodiment, in which, in contrast to the first exemplary embodiment, it consists of nonwoven fabric.
- the fibers 57 are not interwoven with one another in a directed manner but, for example, are knitted or pressed together in a non-directional manner.
- the insert 36 preferably consists of polyester fibers which are impregnated with water-repellent.
- the thickness of the insert 36 can be between approximately 0.1 mm and several millimeters and its density and fine porosity is determined in such a way that both a sufficient filter effect and an adequate air permeability are present.
- the rest of the design of the shielding device 40 and the lighting device is unchanged from the first exemplary embodiment.
- a line 60 is connected to the lower ventilation opening 32 of the housing 16 as shown in FIG.
- the lower ventilation opening 32 can be arranged, for example, in the bottom of the housing 16 or in its rear wall near the bottom.
- the line 60 can be pushed onto a connection piece 61 which surrounds the ventilation opening 32 and projects outwards, or can be inserted into the ventilation opening 32 with a connection piece.
- the vehicle has a spoiler 62 at its front end and the line 60 opens at a somewhat greater distance above the carriageway 63 than the spoiler 62 and its mouth 64 is offset from the direction of travel 66 of the vehicle relative to the spoiler 62.
- the lower ventilation opening 32 and the line 60 connected to it have a smaller cross-section than the upper ventilation opening 30 and the insert 36 covering them.
- the interior 10 When the vehicle is at a standstill, the interior 10 is ventilated from the bottom upwards, since cool air with a low moisture content enters the vehicle floor through the line 60 and the lower ventilation opening 32 and warmer air exits through the upper ventilation opening 30.
- the insert 36 can also be used to remove moisture from the interior 10 with the escaping air.
- Lighting device the upper ventilation opening 30 and / or the lower ventilation opening 32 can also be formed in the pane 18, in the intermediate frame 24 or in the cap 22 instead of in the housing 16.
