Abstract: A retroreflective system is disclosed that includes a retroreflective sheet for retroreflecting light, and a light control film disposed on the retroreflective sheet. For a first wavelength, light incident on the light control film at each of a first and second angles of incidence is retroreflected. For a second wavelength, light incident on the light control film at the first, but not the second, angle of incidence is retroreflected.

Abstract: Generally, the present disclosure relates to light control films. The present disclosure also relates to assemblies incorporating light control films. In some embodiments, the light control films of the present disclosure regulate transmission of one or more of visible light, ultraviolet light, and infrared light that reaches a substrate after exiting the light control film. The light control film comprises waveguiding channels (130) which collect light incident under larger incidence angles towards the surface opposite the incidence surface. The channels are surrounded by a material (140) having a lower refractive index than the one the channel material and can comprise an absorbing pigment.

Abstract: The present disclosure provides a light control film that is capable of transmitting light, or allowing a viewer to observe information, only within a viewing region centered around the normal (perpendicular line) to a surface. The light control film generally blocks information or light outside of this viewing region, and provides security in all directions including right-and-left and up-and-down of the film. The light control film includes a plurality of light-transmissive cavities that are surrounded by a light absorbing material, such that each of the plurality of cavities is optically isolated from adjacent cavities. Each of the light-transmissive cavities effectively block light which enters the cavity outside of a viewing (that is, cutoff) angle.

Abstract: A light redirecting film includes a first layer disposed on a second layer with structured major surfaces of the first and second layers facing each other. An optically reflective layer or a metal layer is disposed between the first and second layers. The first layer can be a hot melt adhesive layer and the second layer can be a polymeric layer. The first and second layers can be unitary layers. The first layer can be a first polymeric layer having a softening temperature T1 and the second layer can be a second polymeric layer having a softening temperature T2 greater than T1. Heating and/or applying pressure to the film changes an optical characteristic of the film by less than about 5%.

Abstract: According to one embodiment, a solar device, comprises one or more photovoltaic cells disposed in an encapsulant and a light control structure including a louver film having a series of louver structures, wherein each louver structure includes one or more groupings of a plurality magnetizable particles aligned at least in a first orientation dispersed in a binding matrix. The light control structure substantially transmits light incident at a first angle and substantially limits transmission of light incident at a second angle. Each louver structure is spaced apart from an adjacent louver structure, wherein each louver structure is substantially aligned in a plane substantially parallel to an adjacent louver structure.
