Definitions
- the invention is based on a lighting device for Vehicles according to the category of claim 1.
- Such a lighting device is known from DE 40 34 258 A1 known.
- This lighting device has a housing, the at least partially an interior of the lighting device limited in which at least one light source is arranged.
- the housing has at least one ventilation opening, in the Area protrudes from the housing an extension to the outside.
- At the The extension is an inner one connected to the ventilation opening Channel formed and a closure part can be placed on the extension.
- Due to the extension and the closure part is an outer Channel formed with the inner channel and the outside atmosphere connected is.
- the closure part has an extension at least on a part of the outer portion surrounding its periphery on. The extension stands outwards from the housing several locking arms starting from the section surrounding the extension attack the closure part and thereby the closure part hold on to the housing.
- the housing is generally made of plastic by injection molding, this type the locking connection of the closure part with the housing complicated and tools that are complex to manufacture of the housing requires what should be avoided. Moreover the closure part is removable from the housing and it is not ensured that the closure part is not synonymous in the event of strong vibrations or during maintenance work on the vehicle unintentionally releases from the housing, so that water splashes into the Interior of the lighting device can penetrate. To do that Locking the captive part to the housing would be a additional assembly effort required, for example Glue the closure part.
- the lighting device for vehicles according to the invention has in contrast, the advantage that the closure part without additional Installation effort is captively attached to the housing.
- FIG. 1 shows sections of an illumination device for vehicles and Figure 2, the lighting device in one Section along line II-II in Figure 1.
- An illumination device shown only in sections in FIGS. 1 and 2 for vehicles, especially motor vehicles, can be designed as a headlight or a lamp his.
- the illustrated embodiment is a headlamp having a housing 10, which is preferably is made of plastic and manufactured by injection molding is.
- Cover plate 12 delimit an interior 14 of the headlight.
- the cover plate 12 can be designed as a smooth plate be or have optical elements.
- the cover plate 12 has a peripheral edge 16 with which it is in a peripheral Groove 18 is attached to the front edge of the housing 10.
- the Housing 10 has an aperture section surrounded by groove 18 20 on, in the light exit direction 22 in the peripheral edge 16 of the cover plate 12 protrudes and opposes the light exit direction 22 tapered.
- At least one light source 23 is arranged, for example inserted into a reflector 24 shown only in sections can be.
- Through the aperture section 20 of the housing 10 becomes a between the edge of the reflector 24 and the inside of the housing 10 existing gap is at least partially covered.
- the housing 10 has at least one ventilation opening 26, through which the interior 14 is connected to the outside atmosphere is.
- the ventilation opening 26 is in an edge region of the housing 10 between the aperture portion 20 and the circumferential Groove 18 arranged.
- the inner channel 28 and the extension 30 point like shown in Figure 2 a rectangular cross-sectional shape, can also have any other cross-sectional shape.
- the extension 30 has two, as shown in Figure 2 Transverse walls 31 and two longitudinal walls 32, 33, the a longitudinal wall 32 of the extension 30 is made wider than the other longitudinal wall 33 of the extension 30.
- the longitudinal wall 32 of the extension 30 protrudes away from the housing 10 beyond the free end of the extension 30, that through the ends of the two transverse walls 31 and the longitudinal wall 33 and the ends of the walls 34 is determined.
- the over the free end of the extension 30 protruding part of the longitudinal wall 32 does not extend across the full width of the Longitudinal wall 32 but only approximately over the width of the longitudinal wall 33.
- the protrusion 36 is at its from the ventilation opening 26 pioneering edge 38 beveled towards the longitudinal wall 32 and has one on its edge facing the ventilation opening 26 shoulder 39 arranged approximately perpendicular to the longitudinal wall 32.
- the free end of the extension 30 is by means of a closure part closable in the form of a cap 42.
- the cap 42 has an outer portion 44 with a cross-sectional shape of the extension 30 adapted cross-sectional shape, is therefore at illustrated embodiment is rectangular.
- the Cap 42 has a bottom in one piece with the outer portion 44 46 on and surrounded by the outer portion 44 is from the bottom 46 Finger 48 with a flat cross section.
- the finger 48 is transverse to the Longitudinal axis 43 of the cap 42 is resiliently pivotable and is close its free end has a recess 49 in the form of a recess or opening up.
- the projection dips 36 in the recess 49 and the edge of the recess 49 engages on the shoulder 39 of the projection 36.
- an outer channel 50 is formed.
- the outer portion 44 of the Cap 42 does not extend to the rear of the housing 10, so that the channel to the housing 10 remains open.
- the outer channel 50 is connected to the inner channel 28.
- the lighting device described above is thus on the extension 30 the one connected to the ventilation opening 26 inner channel 28 available and that with the inner channel 28 and outer connected to the outside atmosphere via the open channel Channel 50.
- This training ensures that the interior 14 is connected to the outside atmosphere without outside moisture, especially water splashes, into the interior 14 can penetrate.
- the housing 10 with the molded on this Extension 30 and the projection 36 arranged on the wall 32 and the cap 42 with the finger 48 formed thereon with the Recess 49 are injection molded using simple tools can be made from plastic. After the cap 42 on the Extension 30 is attached, it can no longer without destruction be solved since their fingers 48 within the extension 30 is arranged and is not accessible. For the captive Attaching the cap 42 is no additional assembly effort required, but only needs this on the Extension 30 to be pushed on.
- the Projection 36 from the longitudinal wall 32 also outwards, that is protrude into the open channel or the outer channel 50, whereby then the finger 48 of the cap 42 is arranged accordingly is that it dips into the gutter.
- the lead could also be 36 also on the other longitudinal wall 33 or on one of the transverse walls 31 of the extension 30 protruding into the inner channel 28 be arranged, the finger 48 also correspondingly is arranged on the cap 42.
