Definitions
- the invention relates to a lighting device, in particular for motor vehicles, such as it is known for example from DE 32 20 704 C2.
- the headlight consists at least of a glass pane, a housing and a Reflector, which together form the interior of the headlamp.
- a Ventilation channel on the lower edge of the housing and a ventilation channel on the upper To provide housing edge, which is integrated in the headlight mounting and as Labyrinth seal are formed.
- the ventilation of the interior of the lighting device is required to the condensation on the inside of the lens and / or to prevent on the reflector.
- condensation would on the one hand Luminosity of the headlamp severely impair and on the other hand possibly too corrosion of the reflector.
- the appearance of the Headlights when condensation forms in the interior of the headlights impaired.
- the arrangement according to the invention has the advantage that by introducing a moisture-absorbing agent in the interior of the headlamp the moisture, which is in the interior of the pig thrower absorbed by this agent and condensation can be avoided even better. Furthermore there is the advantage that the ventilation ducts are designed to be minimal can or that they can possibly be dispensed with entirely, so that a Ingress of moisture from the outside into the headlight is largely excluded is.
- the moisture-absorbing material can both Lighting arrangements that form a closed system, as well as open Systems are used.
- the figure shows a headlight for motor vehicles in a basic representation with the Arrangement of the moisture-absorbing agent in the headlight housing.
- These two components include the Interior 12 of the headlamp.
- these are in the interior Lighting devices usually provided multiple lamps with their Reflectors are arranged in such a way that both far-low and possibly also Fog and / or cornering lights are arranged in the headlights.
- In the figure is symbolic only one reflector with reference number 13 and one lamp with reference number 14 Mistake.
- the Venting and venting ducts are shown, which are denoted in the figure by the reference number 15 are provided.
- a moisture-absorbing Means 16 arranged in the interior 12 of the headlamp.
- this is moisture-absorbent Material packed in a polyester fleece, so that this package on the back of the Interior of the headlamp can be stored in a recess.
- This can this packet fixed for example by means of an adhesive 17 on the back become.
- Another possibility is to have a lattice-like structure 18 to be provided, which is held by clips 19 so that when assembling the package with the moisture absorbing material 16 in the recess of the headlamp stored covered by the grid-like plate 18 and by means of spring-like clips is held.
- Another possibility is to only over the grid-like plate 18 to extend two-thirds of the recess so that the packet passes through it resulting opening is simply placed in the resulting cavity.
- Fig. 1 The location indicated in Fig. 1 for the storage of the package with the moisture absorbent material is just one example. Of course it is too possible, this moisture-absorbing material for example in the interior of the Place the headlamp on the floor and fix it there.
