Motor vehicle lamp lens has moth-eye structure elements at surfaces of the center lens and/or the reflection unit to reduce Fresnel reflection effects

摘要

The lens for a motor vehicle lamp (5), to focus the beam, has a center lens section (9) between the light entry side (2) and the light exit side (6). surrounded by a reflection section (10). A multiple optically active moth-eye structure (16) is at the light entry and/or light exit surfaces of the center lens and/or the light coupling surface (3) and/or uncoupling surface (7) of the reflection section. The structure elements are cylindrical in a diameter of 10-1000 nm, with hollow interiors.
