Abstract:
An optical element, comprising a substrate and at least one optical film. The substrate is at least partially light-transmissive. The optical film comprises at least a first optical feature and is positioned on a contact surface of the substrate. Also, a lighting device comprising at least one solid state light emitter and such an optical element. Also, methods for making an optical element by molding (e.g., film insert molding), bonding or laminating.
