ABSTRACT:
The subject invention comprises a headlamp moisture control system that comprises at least one desiccant and at least one valve. The desiccant comprises an interior desiccant surface that forms an intake passageway and an exterior desiccant surface that forms at least one exhaust passageway. Further, the exterior desiccant surface area has a surface area that is greater than the interior desiccant surface area. The at least one valve can comprise an intake valve and an exhaust valve or it can comprise a combination valve. In either embodiment, the at least one valve prevents the desiccant from constantly being exposed to air that contains moisture. The moisture control system prevents moisture from entering a headlamp assembly during the cooling of a headlamp by only allowing air to enter the headlamp assembly through the intake passageway over the interior desiccant surface. To prevent the desiccant from being saturated, the desiccant will be regenerated during the operation of the headlamp assembly by exhausting dry, heated air from the headlamp assembly through the at least one exhaust passageway over the exterior desiccant surface. Thus, the desiccant will be regenerated and ready to absorb moisture from the incoming air once the headlamp assembly is turned off and begins to cool.
