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 5µm 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.
(EN)
In one embodiment the component (1) comprises a light-reflecting housing (2). The housing (2) comprises a matrix material (21) made of of a light-permeable plastics material, and particles (22) made of a glass ceramic which are embedded therein. The particles (22) have an average diameter of at least 5 µm. The particles (22) comprise a glass matrix (31) and crystallites (32). A difference in the refractive index between the glass matrix (31) and the crystallites (32) is at least 0.5. The crystallites (32) have an average diameter of between 20 nm and 0.5 µm inclusive.

Selon un mode de réalisation, la présente invention concerne un composant (1) comprenant un boîtier (2) réfléchissant la lumière. Le boîtier (2) comprend un matériau matriciel (21) en matière plastique translucide ainsi que des particules (22) en vitrocéramique incorporées dans ladite matière plastique. Les particules (22) présentent un diamètre moyen d'au moins 5 µm. Les particules (22) comprennent une matrice de verre (31) et des cristallites (32). Une différence d'indice de réfraction entre la matrice de verre (31) et les cristallites (32) est d'au moins 0,5. Les cristallites (32) présentent un diamètre moyen dans la plage comprise entre 20 nm et 0,5 µm.
