Benefits of technology

The patent describes a way to make a special material that can control the direction of light. It can be cut and shaped using a sharp object like a blade. The material has tiny louvers that are created by adding a layer of opaque material to slits that have been made in the material. When the opaque material is added and cured, the louvers close up to form a single structure. This structure can be strengthened by using an adhesive material or heat to fuse the slits together. The technical effect of this invention is the creation of a special material that can control the direction of light in a precise and custom way.

Problems solved by technology

The conventional light control films may exhibit certain disadvantages and can be relatively difficult and / or expensive to manufacture at an industrial scale.

Embodiment Construction

[0025]Referring more specifically to the drawings, for illustrative purposes, the present invention is embodied in the apparatus and method generally shown in the preceding figures. It will be appreciated that the apparatus and method may vary as to configuration and as to details of the parts and / or steps without departing from the basic concepts as disclosed herein. Furthermore, elements represented in one embodiment as taught herein are applicable without limitation to other embodiments taught herein, and in combination with those embodiments and what is known in the art.

[0026]The present invention particularly seeks to provide angularly selective sheet-form light control materials capable of providing variable transmissivity depending on the angle of incidence and particularly providing high levels of opacity at high incidence angles (generally above about 40 degrees or so).

[0027]The following embodiments of the present invention are generally directed to a sheet-form optical ar...

Abstract

An angular selective light control sheeting and a method of making the same are disclosed. The light control sheeting includes a layer of an optically clear elastic material which has a series of parallel slits formed by means of surface slitting with a sharp object such as a razor or blade. Each slit is filled with an opaque material which prevents light transmission through the slit walls. The method includes a step of slitting of an elastic, optically transmissive plastic sheet with a blade and forming at least one array of substantially parallel linear slits in a surface of the sheet, a step of stretching the sheet in a direction perpendicular to the linear slits, and a step of introducing an opaque material into the interior of the slits.
