  • Patent number: 11022272
    Abstract: An optical film made from a light-permeable material includes a surface and an optical microstructure having a plurality of elevations. The elevations of the microstructure protrude from a reference plane, which is parallel to the surface. The elevations of the microstructure each have a flank section which adjoins the reference plane and forms a uniform angle with the reference plane. The uniform angle is in a range from about 33° to about 42° or in a range from about 35° to about 40°. The optical film according to the invention makes it possible to provide a light fixture with relatively strong glare suppression and at the same time to produce a preferred light distribution curve (LDC). In addition, it can be relatively flexibly moulded and cost-effectively produced.
