Abstract
In one embodiment, the component comprises a light reflective housing. The housing comprises a matrix material of a light-transmittive plastic and particles of a glass ceramic embedded therein. The particles comprise a mean diameter of at least 5 μm. The particles comprise a glass matrix and crystallites. A refractive index difference between the glass matrix and the crystallites is at least 0.5, and the crystallites exhibit a mean diameter between 20 nm and 0.5 μm, inclusive.
