Title
(DE) Bauteil mit einem reflektierenden Gehäuse und Herstellungsverfahren für ein solches Bauteil
Abstract
(DE)

In einer Ausführungsform umfasst das Bauteil (1) ein lichtreflektierendes Gehäuse (2). Das Gehäuse (2) umfasst ein Matrixmaterial (21) aus einem lichtdurchlässigen Kunststoff sowie darin eingebettete Partikel (22) aus einer Glaskeramik. Die Partikel (22) weisen einen mittleren Durchmesser von mindestens 5 µm auf. Die Partikel (22) umfassen eine Glasmatrix (31) und Kristallite (32). Ein Brechungsindexunterschied zwischen der Glasmatrix (31) und den Kristalliten (32) liegt bei mindestens 0,5. Die Kristallite (32) zeigen einen mittleren Durchmesser zwischen einschließlich 20 nm und 0,5 µm auf. embedded image
