Abstract (en)
[origin: WO2015184457A1] A hybrid optical system, and lighting devices including the same, are provided. The hybrid optical system includes a cellular optical element a light control film. The cellular optical element includes a first opening, a second opening, and a space defined therebetween. The light control film includes a single layer of light transparent material having a first side and a second side, and a plurality of first microstructures formed on the first side. The light control film is located within the space of the cellular optical element. The light control film may include a plurality of second microstructures formed on the second side to reduce glare. The hybrid optical system may include a plurality of interconnected cellular optical elements.
