Beschreibung
Zusammenfassung:	Light control films, and lighting devices including the same, are disclosed. The light control films include a single layer of light transmitting material having a first side and a second side. A plurality of first microstructures are formed in the first side. The first microstructures are configured to receive incident light from a light source and produce an off axis (e.g. batwing) light distribution in a field downstream of the second side of the light control film. In some embodiments, a plurality of second microstructures is formed on the second side of the light control films and are configured to reduce the glare produced by light emitted from the light source passing through the film.
