Definitions

  • the invention relates to a headlight or a lamp for a motor vehicle, with a lens, a housing, light sources arranged in the housing, reflectors assigned to them and with a ventilation system which comprises at least one supply air opening, one exhaust air opening and a blower.
  • Such an embodiment can be found in FR 2 701 756 AI.
  • the blower built into the headlight housing sucks in fresh air through an air inlet opening in the rear wall of the housing and presses it - guided by air guiding devices - along the lower housing wall against the lens, along which the air flows, and - again through air guiding devices - at the to flow out along the upper housing wall and through an upper exhaust air opening provided in the area of the rear wall of the housing.
  • the resulting air exchange is intended to lead moist air out of the headlight in order to prevent the moisture contained in the air from condensing on the lens when the lens or the entire headlight cools down.
  • a clear lens is used for headlights or new generation lights.
  • the predetermined light distribution is then achieved through specific geometric design of the reflectors.
  • the reflectors can also be used as carriers of light emission optics for additional lights such as turn signals or fog lights.
  • the headlight or the lamp is then enclosed in a housing on the engine compartment side.
  • three or even four light sources are arranged in one headlight. This simplifies assembly, since all lights are already attached to the vehicle by installing the headlight. Furthermore, this gives the headlight a technically very interesting impression for an observer from the outside. By accommodating so many However, light sources in a relatively small area pose new problems in terms of heat development. Temperatures of up to 230 degrees are no exception in such a headlight. This is particularly true 'when the vehicle is of great importance, that is, eliminating the cooling by the wind. Due to the heat development, deformation of the lens or other plastic parts can occur.
  • plastics are usually used as materials for the housing or the reflector or for sealants, in particular PC - polycarbonate, UP - unsaturated polyester, PP-GF - glass fiber reinforced polypropylene (ester) and PVC - Polyvinyl chloride.
  • PC - polycarbonate UP - unsaturated polyester
  • PP-GF - glass fiber reinforced polypropylene (ester) and PVC - Polyvinyl chloride.
  • these plastics i.e. the plastics contain outgassing volatile components. Components that flow out of such plastics are e.g. Plasticizers, amines (PUR foam catalysts), lubricants, stabilizers, flame retardants or solvents.
  • Fogging leads to fogging or graying of the lens of the reflectors or to decomposition of the plastic. Fogging increases exponentially with temperature, e.g. in "Temperature dependence of the fogging phenomenon” Kunststoffe 83 (1993), by F. Loock, Th. Lampe, A.M. Bahadir described.
  • the invention has for its object to prevent the risk of graying or fogging of the lens or the reflectors in a headlight or a lamp of the new generation by fogging.
  • Luminaire this object is achieved in that at least one of the headlight parts at least partially A Ausfoggenden plastic is that the blower is an air extracting fan from the housing, and that air guiding devices are arranged within the housing so that the blower leads the air away from the lens and targeted past heat pockets to the rear of the housing facing away from the lens.
  • the air flowing around the components, in particular the reflectors and the housing, is cooled, so that the constituent parts that are emitted from these parts are reduced.
  • the air duct provided according to the invention also has an effect on the amount of fogging condensate in the headlight. Passing the air flow past the reflector is particularly important since, due to its complicated geometric design, this requires special protection against condensate deposition in order to ensure or maintain the predetermined light distribution. It is also important that the fan guides the air away from the lens, since volatile components would be inflated onto the lens when the windshield was blown.
  • the following plastic parts are cooled by the air flow guided according to the invention, so that a smaller amount of volatile constituents is released from the plastic parts.
  • the remaining, still volatile components are removed from the headlamp by the increased air exchange. It is important for this that the air flow flowing from the supply air opening to the exhaust air opening is increased sufficiently.
  • the fan is arranged on or in a cover which removably closes an opening in the rear of the housing.
  • a cover which removably closes an opening in the rear of the housing.
  • the lid also serves as a fastening attachment for a headlamp leveling device or other electrical see attachments.
  • the air guiding devices comprise throughflow openings in the reflector, these throughflow openings preferably being arranged close to the light source.
  • the air guiding devices comprise gaps between the outer reflector edge and the housing wall.
  • the function of the fan is advantageously electrically coupled to the parking light.
  • the blower is actuated at the same time, which is thus also switched on when the vehicle is stationary, in order to be able to compensate for the lack of headlight cooling due to the lack of a headwind.
  • the fan can be switched off after the headlight or the lamp has been switched off after a predetermined run-on time. As a result, the fully heated headlamp is cooled for a while, even when the vehicle is stationary, and prevents it from running out.
  • the headlight has several light sources of different light intensity, it is advisable to assign the fan to the light source with the strongest light, since this emits the most heat and thus represents the most critical point in the headlight.
  • This fan arrangement achieves particularly effective heat dissipation.
  • the invention is explained in more detail below using an exemplary embodiment.
  • the single figure shows a headlight with a ventilation system in cross section.
  • the headlight 1 has a housing 5 and a lens 2.
  • Light sources 3 and reflectors 4 are provided in the housing 5. The light emitted by the light sources 3 is emitted to the outside via the reflectors 4 through the lens 2.
  • the light sources 3 can be attached, for example, to the reflectors 4 or also to other attachment approaches connected to the housing 5.
  • the reflectors 4 can also be used as carriers for light emission optics for further light sources, which are arranged on the side of the reflector 4 facing away from the lens 2.
  • several light sources 3 are arranged on a reflector; the desired light emission distribution is achieved by targeted geometric design of the reflectors 4. This makes it possible to use a clear lens 2.
  • the lens 2 is therefore made of a specially hardened glass or a specially adjusted plastic, in particular PC-H (polycarbonate), in order to avoid deformations due to the action of heat.
  • PC-H polycarbonate
  • the housing 5 and / or the reflectors 4 and / or sealant between the components are made of plastic.
  • Plastics such as PC - polycarbonate, UP - unsaturated polyester, PP-GF - glass fiber reinforced polypropylene (ester) and PVC - polyvinyl chloride have additives such as plasticizer components, flame retardants or lubricants to produce the desired properties of the plastics. These volatile constituents outgas from the plastics, particularly at high temperatures. This process is generally described as fogging. After the headlight has cooled down, these volatile components settle on the reflectors or lens and cause them to turn gray. It is also possible that the properties of the Plastics change unintentionally. The temperature of the plastic has a significant influence on the amount of fogging condensate. For example, an increase in temperature from 90 ° C to 120 ° C for an instrument panel film leads to a tenfold increase in fogging condensate.
  • the housing 5 On the side of the reflectors 4 facing away from the light exit side, the housing 5 has an opening 25.
  • the opening 25 is closed with a cover 6.
  • the cover 6 serves as a fastening attachment, for example for a control device for a headlight range control 8 or plug contacts, not shown.
  • the cover 6 has an exhaust air opening 15, in which the fan 7 is arranged.
  • the arrangement of the blower 7 in the cover 6 makes it possible to retrofit headlights not previously equipped with a blower with a blower.
  • the blower 7 is, for example, a commercially available fan, such as is used in computer housings.
  • the volume flow is, for example, 11 m 3 / h with a current consumption of 0.09 amperes and a voltage of 13 volts; the power consumed by the fan is therefore very low and can also be accepted from an energy point of view.
  • the components around which the flow flows such as the reflectors 4 or the housing 5, are cooled, so that the volatile constituents which outgas from these parts are reduced.
  • the increased air exchange also has an effect on the amount of fogging condensate in the headlight.
  • supply air openings 10 which are arranged in the area behind the lens 2 on the housing circumference, can be enlarged and, in order to prevent the ingress of dust, engine ambient vapors and / or water, additional filter measures (for example carbon filters in conjunction with, for example, GORO -
  • the invention offers the advantage that the lens 2 is exposed to a lower heat load due to the cooling effect and can therefore also be produced from a conventional plastic.
  • the reflectors can have specifically arranged throughflow openings 31, in which case the choice of the gap width of gaps 30 and the size of the through opening 31 allows the air flow to be guided such that it is directed past heat nests. Furthermore, passing the air flow past the reflector 4 is particularly important, since the reflector 4, due to its complicated geometric configuration, which ultimately determines the light distribution, is particularly to protect against condensate deposits, since otherwise the predetermined light distribution is not maintained. The path of the air flow is shown by the arrows. It is particularly important that the blower 7 guides the air away from the lens. Blowing on the lens similar to blowing on the windshield when ventilating the vehicle interior would be undesirable, since this would also specifically inflate the volatile components onto the lens 2. Furthermore, the reflector 4 can experience material decomposition due to the outgassing volatile constituents, which ultimately also influences the light distribution.
  • one of the light sources 3 is designed as a fog light
  • the blower 7 is arranged in the area of the fog light, since the fog light also represents a particularly large heat source due to its particularly high light output.
  • the blower 7 is electrically coupled to the parking light. In this way it is ensured that the headlight 1 is ventilated by means of the blower 7 even if the parking light is actuated unintentionally. It is also contemplated that
  • Blower 7 after switching off the headlamp 1 a predetermined run-on time is still running, so that any volatile constituents still present are removed from the headlamp 1, and the headlamp is cooled to an acceptable operating temperature so that the further outgassing of volatile constituents is reduced to a minimum .
