Abstract: This disclosure describes a composition that includes a bulk diffuser that includes a film having a major surface; the film includes a polymer, and a scattering element. The scattering element includes a silicone bead having a mean particle diameter in a range of 2 micrometers (μm) to 9 μm. The linear density of the film is at least 5.1 Wi*μm, wherein the linear density equals the product of the mass fraction of the silicone bead (Wi) and film thickness in micrometers (μm). This disclosure further describes methods of making the film and the bulk diffuser and methods of using the film including, for example, as a bulk diffuser in a sign box.

Abstract: Dual-sided optical films have extended prisms formed in one major surface, and extended lenslets formed in an opposite major surface. Some or all of the prisms are compound prisms, in which the two inclined surfaces of each compound prism each include a tip portion, a base portion, and an intermediate portion disposed between the tip portion and the base portion, the intermediate and tip portions forming a concave shape and the intermediate and base portions forming a convex shape, or vice versa. When obliquely incident light, e.g. from a light guide, is incident on the prism side of the film, an output beam emerges from the lenslet side of the film. The output beam has an intensity distribution with a sharp left beam edge and a sharp right beam edge, these beam edges having 10%-to-90% transition angles of no more than 7, 6, 5, 4, 3, or 2 degrees.

Abstract: An optical film has a structured surface with elongated lenslets formed therein and an opposed structured surface with elongated prisms formed therein. The lenslets extend parallel to each other and to an elongation axis which is generally parallel to the film plane, and the prisms also extend parallel to each other and to the elongation axis. The prisms are grouped into separated clusters of adjacent prisms. Each prism cluster is associated with a corresponding one of the lenslets, and has at least 3 prisms. Each lenslet defines a focal point and a focal surface. Vertices of the prisms in a prism cluster are disposed at or near the focal surface of the associated lenslet. When illuminated with oblique light, each lenslet/prism cluster pair, and optionally the optical film as a whole, may produce N angularly separated light beams, N being the number of prisms in each prism cluster.

Abstract: Dual-sided optical films have extended split spreading structures formed on one major surface, and extended prisms formed on an opposite major surface. One portion of each split spreading structure has a low light spreading characteristic, and another portion has a high light spreading characteristic. For each split spreading structure, the low light spreading portion may be disposed alongside the high light spreading portion. The split spreading structures may be arranged in a one-to-one correspondence with the prisms. Light that enters a given prism from one inclined surface thereof can be associated primarily with light transmitted through the low light spreading portion of the split spreading structure, and light that enters the given prism from the other inclined surface thereof can be associated primarily with light transmitted through the high light spreading portion.
