Abstract

Für eine Fahrzeug-Leuchtenanordnung wird eine langfristig wasserdichte Kapselung eines Leuchtengehäuses vorgeschlagen, welche das Anspritzen eines thermoplastischen Elastomers an die Gehäuseaußenfläche zumindest im Bereich einer Gehäusetrennfuge vorsieht. Dabei bildet sich, gegebenenfalls unter zusätzlicher Verwendung von Haftvermittlern, eine haftfeste und kriechwasserdichte Verbindung zwischen dem Material des Gehäusekörpers und dem thermoplastischen Elastomer. Durch die Verwendung des thermoplastischen Elastomers und dessen Aufbringen in einer Gussform ergibt sich ein günstiges Herstellungsverfahren.

Figure imgaf001
For a vehicle lamp assembly, a long-term waterproof encapsulation of a lamp housing is proposed, which provides the injection molding of a thermoplastic elastomer to the housing outer surface at least in the region of a housing separation joint. In this case, if necessary with the additional use of adhesion promoters, an adhesive and Kriechwasserdichte connection between the material of the housing body and the thermoplastic elastomer is formed. The use of the thermoplastic elastomer and its application in a mold results in a favorable manufacturing process.
