Definitions
- the present invention relates to a motor vehicle lighting device according to the preamble of claim 1.
- a lighting device device is in each case from DE 20 2012 009 488 U1 , the US6,071,000 , the JP 2002 124123 A , the DE 10 2013 218 329 A1 and the DE 195 24 163 known.
- the present invention is not limited to headlights, but also relates to signal lights, in particular rear lights, but also separate front lights.
- the term lighting device includes headlights and signal lights.
- the ventilation and ventilation of the lighting devices of motor vehicles serves to remove moisture from the interior of the lighting device. Moisture that has condensed on the inside of the cover pane in particular is less attractive from the outside than it is veil visible. Some end customers mistakenly assume that this is a defect and visit their dealers to complain about the incident.
- the ventilation of the lighting device should prevent the formation of such a water film as far as possible and eliminate any water film that may have formed anyway.
- the present invention differs from the prior art mentioned at the beginning by the characterizing features of claim 1.
- the ventilation opening is arranged transversely to the housing wall adjoining the ventilation opening in the air flow on the outside of the sealing bed, that a ventilation opening is located transversely to the housing wall on the outside of the sealing bed, that the lighting device has a further air duct structure which, in the direction of the airflow from the relative wind, is directly in front of the ventilation opening in the said headwind air flow protrudes, and that air-guiding structures such as channels and/or ribs and/or tubes are arranged in the interior of the lighting device, which are set up by their arrangement and shape to direct at least parts of a ventilation volume flow passing through the lighting device to specific areas in the lighting device conduct, where a particularly large amount of moisture occurs.
- This active deflection of air increases the air volume flowing through the lighting device per unit of time, ie the air volume flow.
- the increased air volume flow can absorb more moisture per unit of time and out of the lighting device carried out as a smaller air volume flow, so that there is an improved and more effective ventilation.
- the invention reduces the risk of water film formation and accelerates the dissolution of a water film that has already formed on the cover pane of a headlight or a rear light or a front light while the motor vehicle is in motion.
- the air guiding structure is a part of the housing.
- the air duct structure can be part of a component with which a joint between the housing and/or the cover plate on the one hand and a surrounding part of the motor vehicle on the other hand is covered.
- a further preferred embodiment is characterized in that the ventilation opening is located at a point on the housing where the air duct structure generates a dynamic pressure in an air flow that is driven along the housing when used as intended in a moving motor vehicle, and that the ventilation opening is at a point of the housing where there is no dynamic pressure or at least a smaller dynamic pressure or even suction.
- the motor vehicle lighting device prefferably has an air duct structure which, in the direction of the airflow from the airflow, protrudes into the airflow from the airflow directly behind the ventilation opening.
- a further preferred embodiment is characterized by a filter which is arranged between the ventilation opening and the interior space and which, due to the size of its pores, is designed to allow air to flow in, but in particular not to let through insects and smaller and larger dirt particles such as dust and grains of sand .
- the ventilation opening lies behind the first air ducting structure in relation to the direction of the air passing outside the housing driven by the relative wind, so that the air ducting structure lies in front of the ventilation opening in the incoming air in this direction.
- a further preferred configuration is characterized in that the ventilation opening with the first air guiding structure is arranged on a first housing side which is opposite a second housing side on which the ventilation opening with the further air guiding structure is arranged.
- first housing side and the second housing side lying opposite it in one embodiment are respectively a right side and a left side of the lighting device when the lighting device is used as intended, or vice versa.
- first side of the housing is a lower side when the lighting device is used as intended, and the second side of the housing opposite it is an upper side of the lighting device when the lighting device is used as intended, so that the air flow Flows through the interior from bottom to top.
- a further preferred configuration is characterized in that the ventilation opening is arranged in the lateral direction on a side lying opposite the side of the ventilation opening.
- the figure 1 an arrangement of a motor vehicle lighting device 10 and at least one surrounding part 12, 14 in a vertical section.
- the surrounding parts 12, 14 are, for example, a part of the vehicle body, a part of an adjacent lighting device which has its own housing, or a part of a radiator of the motor vehicle adjacent to the lighting device.
- the arrangement shown results when the lighting device is used as intended, in which the lighting device is installed in a motor vehicle.
- the cutting plane of the vertical section is the xz-plane of a right-handed and right-angled coordinate system, whose x-direction corresponds to the direction of the longitudinal axis of the vehicle, whose y-direction is transverse to it and parallel to the horizon, and whose z-direction is transverse to the x-direction, transverse to the y- direction and vertically upwards.
- the lighting device is a headlight.
- the invention is not limited to headlights, but can also be implemented in front lights and rear lights.
- At least one light module 16 is arranged inside the lighting device 10, which is used to generate a light distribution that conforms to the rules for the lighting device, be it a headlight light distribution or a Signal light distribution is set up.
- the lighting device 10 has a housing 18 and a transparent cover plate 20 .
- the cover disk has the shape of a shell, which has a transparent base 22 and an edge 24 that runs around the base 22 and protrudes from it like a wall. With its transparent base 22 , the cover plate covers the light exit surface of the housing 18 . The edge 24 is received by a sealing bed 26 running around the light exit opening of the housing 18 and is held tightly and firmly in the sealing bed 26 .
- the lighting device has a ventilation opening 28 and a ventilation opening 30 .
- the ventilation opening serves to allow air to flow into an interior space 32 of the lighting device that is delimited by the housing 18 and the cover plate 20 .
- the vent opening 30 serves to allow air to flow out of the interior space 32 .
- An air duct structure 34 is arranged on the outside of the ventilation opening 28 , that is to say outside of the interior space 32 , on the housing 18 .
- This air guiding structure 34 can be a rib protruding from the housing or a stub protruding from the housing. It is essential that the air ducting structure 34 is set up and arranged to deflect air 36, which flows along the outside of the lighting device 10 when the lighting device 10 is used as intended in a moving motor vehicle due to the influence of the airstream, into its interior 32.
- the air 36 passes through gaps 50, which are located between the lighting device 10 and the lighting device surrounding environmental parts 12, 14, in the body of the motor vehicle.
- the air duct structure 34 dams the air flow and, through the damming effect, generates an overpressure dependent on the relative wind.
- the air guiding structure 34 is located in the flow direction of the inflowing air 36 behind the ventilation opening 28 in the inflowing air 36 so that the overpressure at the ventilation opening 28 is established. As a result, there is a pressure gradient between inside and outside, which deflects part of the air 36 flowing in from the outside and allows it to enter the interior 32 through the opening 28 .
- the air duct structure 34 is an integral part of the housing 18 or the cover plate 20. In the exemplary embodiment shown, the air duct structure 34 is a part of the housing 18.
- the air duct structure 34 is preferably made of the same material as the housing or the cover plate. It is therefore particularly preferably made of plastic and is molded onto the respective component during injection molding of the housing or the cover plate.
- the ventilation opening 30 is arranged spatially remote from the ventilation opening 28 .
- the ventilation opening is the flow cross section of a connecting piece 37 which is arranged on a rear side 38 of the housing 18 facing away from the light exit side of the housing 18 and which has a downwardly curved or angled profile. Air flowing in through the ventilation opening 28 absorbs moisture in the interior 32 of the housing 18 and transports the absorbed moisture out of the housing 18 via the ventilation opening 30 .
- the ventilation opening 28 and the ventilation opening 30 on the lighting device 10 are so arranged so that when used as intended in a motor vehicle under the influence of the relative wind, a greater air pressure is set in the ventilation opening 28 than in the ventilation opening 30.
- the ventilation opening 28 is located where the air duct structure 34 generates a dynamic pressure in an air flow driven along the housing 18 when used as intended in a moving motor vehicle, and the ventilation opening 30 is located at a point where there is no dynamic pressure or at least a smaller dynamic pressure or even a suction prevails.
- the ventilation opening 28 is located transversely to the housing wall adjoining the ventilation opening 28 in the air flow 36 on the outside of the sealing bed 26. In relation to the direction of the air 36 flowing on the outside of the housing, driven by the relative wind, the ventilation opening 28 is located behind the first air duct structure 34 in the incoming air 36.
- the fact that the ventilation opening 28 is located on the sealing bed 26 results in the advantage of a particularly high dynamic pressure.
- the dynamic pressure is particularly high there because the sealed bed 26 already protrudes outwards into the air flow 36, so that there is a narrower flow cross section of the inflowing air compared to the flow cross section occurring directly in front of the sealed bed 26 on the outside of the lighting device 10.
- the air-guiding structure 34 which still protrudes outwards beyond the sealed bed 26, catches part of the air 36 flowing past the sealed bed 26 on the outside and diverts this part through the ventilation opening into the interior.
- the air duct structure forms with its end, protruding into the stream of air flowing past the dense bed is an obstacle. As a result of this flow obstruction, the above-mentioned increased overpressure results.
- the reference value compared to which the dynamic pressure is increased, would be a pressure that would result under otherwise identical conditions if the air-guiding structure were omitted.
- FIG figure 2 shows a detail 41 from FIG figure 1 in enlarged form.
- the figure 2 the air duct structure 34 together with the ventilation opening 28 in an enlarged representation and with an additional filter 40 which is arranged between the ventilation opening 28 and the interior 32.
- the filter Due to the size of its pores, the filter is designed to allow air to flow in, but not to let through insects and smaller and larger dirt particles such as dust and grains of sand. As a result, rapid contamination of the lighting device can be avoided.
- the filter can be overmoulded as an insert, or with the help of other joining techniques, such as e.g. B. hot stamping, are attached. This applies to all of the configurations presented here.
- FIG. 3 shows a lighting device, which differs from the lighting device by the design of its ventilation opening 42 according to FIG figures 1 and 2 differs.
- the lighting device 10 according to FIG. 1 shows a lighting device, which differs from the lighting device by the design of its ventilation opening 42 according to FIG figures 1 and 2 differs.
- the lighting device 10 according to FIG. 1 shows a lighting device, which differs from the lighting device by the design of its ventilation opening 42 according to FIG figures 1 and 2 differs.
- the vent opening 42 is located transversely to the housing wall in the air flow 36 on the outside of the sealing bed 26
- Air duct structure 34 is in this direction in front of the vent opening 42 in the incoming air 36. Due to this position, the air sweeping past the outside of the housing 18 exerts a suction effect on the interior space 32 . A negative pressure is therefore created in the ventilation opening 42.
- the pressure that is established is in particular below the value of the pressure that would arise in the ventilation opening 42 without the suction effect resulting from the air flow 36.
- the position of the ventilation opening 42 in the manner shown on the sealing bed 26 also results in a particularly high suction effect, because the sealing bed already protrudes outwards into the air flow.
- the additional air duct structure 44 which projects outward beyond the sealed bed 26, deflects the air 36 flowing past the sealed bed 26 to the outside even further outwards, which reduces the flow cross section of this air and thus increases its flow speed.
- the aforementioned increased suction effect results in the ventilation opening 42 arranged transversely to this air flow in the flow shadow of the further air guiding structure 44 .
- the further air duct structure 44 is preferably produced in exactly the same way as the first air duct structure. It applies to all air duct structures of this application that they, regardless of whether they are an inlet or an outlet, preferably consist of the material from which the entire component to which the air duct structure belongs is made. In 3 the air inlet is made of the material of the housing and the outlet is made of the material of the disc.
- the ventilation opening 28 with the first air guiding structure 34 is preferably arranged on a first housing side 18.1, which is opposite a second housing side 18.2, on which the ventilation opening 42 with the further air guiding structure 44 is arranged. This promotes a good flow through the interior 32 and thus an effective removal of disruptive moisture.
- the first side 18.1 and the second side 18.2 lying opposite it are respectively a right side and a left side of the lighting device when the lighting device is used as intended, or vice versa.
- first side 18.1 is a lower side when the lighting device is used as intended
- second side 18.2 lying opposite it is an upper side of the lighting device when the lighting device is used as intended, so that the air flow flows through the interior from bottom to top.
- the air entering the interior of the lighting device is caused by the prevailing temperature due to the proximity of the hot engine and/or radiator and/or the light sources arranged there, be they semiconductor chips or incandescent lamps or gas discharge lamps.
- the heating produces a convection-driven air flow, which is directed from bottom to top, which intensifies and thus improves the airstream-driven flow, which is also directed from bottom to top in this embodiment.
- the ventilation opening is arranged on a side opposite to the side of the ventilation opening in the lateral direction.
- the air therefore flows not only from bottom to top, but also transversely from right to left (or from left to right) through the lighting device. This favors a spatially uniform removal of moisture from the interior over the surface of the cover pane.
- a further preferred embodiment provides that air-conducting structures 52 such as channels and/or ribs and/or tubes are arranged in the interior 32 of the lighting device 10, which are set up by their arrangement and shape to direct at least parts of the ventilation air volume flow preferably to the critical areas in of the lighting device 10 where, for example, a particularly large amount of moisture occurs. This can be the lower corners of the interior 32 of the lighting device 10, for example.
- air-conducting structures 52 such as channels and/or ribs and/or tubes are arranged in the interior 32 of the lighting device 10, which are set up by their arrangement and shape to direct at least parts of the ventilation air volume flow preferably to the critical areas in of the lighting device 10 where, for example, a particularly large amount of moisture occurs. This can be the lower corners of the interior 32 of the lighting device 10, for example.
- the figure 4 shows an embodiment in which the ventilation opening 28 is integrated with an air duct structure 46 in the lower part of the edge 24 of the cover plate 20.
- figure 5 shows a detail 51 of this embodiment in an enlarged view.
- the lower part of the rim 24 is placed in a dense bed 26 held, which is a part of the housing 18 in the illustrated embodiment.
- a dense bed 26 held, which is a part of the housing 18 in the illustrated embodiment.
- the ventilation opening 28 which is also preferably provided with a filter 40 here. It also applies here that the filter 40 is set up to prevent the ingress of insects and dirt particles.
- the air duct structure 46 is the combination of the middle part 24m of the edge 24 lying between the lower part 24u and the upper part 24o of the edge 24, which extends in the vertical direction (z.direction), and of this middle part 24m horizontally projecting rib 24R.
- the combination of the lower part, the middle part and the upper part of the edge forms a step.
- the rib protruding horizontally from the vertical part 24m of this step thus protrudes into the airflow driven by the relative wind, which accumulates at the step.
- This accumulation of air is further intensified by the rib 24R below the opening 28, so that the excess pressure is set on the outside of the ventilation opening 28.
- the configurations with the ventilation-side air duct structure 34 and with the ventilation-side air duct structure 46 can each with both the ventilation-side air duct structure of the figure 1 as well as with the ventilation-side air guide structure of the figure 3 be combined.
- the figures 1 , 3 and 4 show in addition to configurations of Lighting devices 10 also in each case an arrangement of such a lighting device together with surrounding parts 12, 14 in a component environment as it results when the respective lighting device 10 is used as intended.
- These figures show aspects of the technical environment of the invention in the form of an arrangement of a motor vehicle lighting device 10 and at least one surrounding part 12, 14, in which the lighting device 10 and the surrounding part 12, 14, when used as intended, delimit an air gap 50 through which the motor vehicle is moving an air stream 36 passes through, which flows past the lighting device at the side.
- the flow past can occur on an upper side and/or an underside and/or a right side and/or a left side of the lighting device 10 .
- This technical environment results from an arrangement of a motor vehicle lighting device and at least one surrounding part, in which the lighting device and the surrounding part delimit an air gap when used as intended, through which an airflow stream passes when the motor vehicle is moving, which flows past the side of the lighting device, and with a ventilation opening and with a vent hole.
- the lighting device has at least one air duct structure, which protrudes in the direction of the headwind airflow either directly in front of the ventilation opening or directly behind the ventilation opening in said headwind airflow.
- the lighting device has at least one ventilation opening and at least one vent opening and an air duct structure that in the direction of the air flow either directly in front of the Vent opening or protrudes immediately behind the ventilation opening in said headwind air flow.
- the surrounding parts 12, 14 are, for example, parts of the vehicle body, parts of an adjacent lighting device which has its own housing, or parts of a radiator of the motor vehicle adjacent to the lighting device.
- the flow speed and the dynamic pressure depend on the speed of the motor vehicle and increase with increasing speed.
- the lighting device is preferably a headlight or a front light.
- the arrangement aspects promote the creation of a high air volume flow between the interior 32 of the headlight between a ventilation opening and a ventilation opening in that the wind-driven air flow, which flows in through the gap between the headlight and the surrounding parts, is used to generate a pressure drop through dynamic pressure and/or suction will.
- a dynamic pressure is generated at a ventilation opening arranged there, which allows air to flow into the interior 32 .
- Downstream one than Flow obstacle acting further air duct structure is generated at a ventilation opening arranged there, a suction that allows air to escape from the interior.
- the air duct can not only form part of the headlight housing and/or the cover plate, but it can also be part of a so-called CW rubber.
- a CW rubber is understood to mean a component which covers body joints in a closing manner in order to reduce the air resistance of the motor vehicle.
- the air duct in this case is an opening in the CW rubber.
- the invention allows the air duct structures and ventilation openings to be adapted to the air flow conditions and ventilation requirements prevailing on a specific vehicle type by adapting the position, cross-sectional area of the air duct structures and ventilation openings and vent openings and their orientation in relation to the air flow, so that dynamic pressure and/or suction a differential pressure between ventilation openings and vent openings is achieved.
