    摘要： Light sources are disclosed. A disclosed light source includes an optically reflective cavity that includes an input port for receiving light and an output port for transmitting light, a lamp that is disposed at the input port, and an optical stack that is disposed at the output port. The optical stack includes a forward scattering optical diffuser that is disposed at the output port and has an optical haze that is not less than about 20%, and an optical film that is disposed on the optical diffuser. The optical film enhance total internal reflection at the interface between the optical film and the optical diffuser. The optical film has an index of refraction that is not greater than about 1.3 and an optical haze that is not greater than about 5%. The optical stack also includes a reflective polarizer layer that is disposed on the optical film. Substantial portions of each two neighboring major surfaces in the optical stack are in physical contact with each other.

    摘要： A process and apparatus for producing a gradient nanovoided article, a gradient nanovoided coating, and a gradient low refractive index coating is described. The process includes providing a first solution of a polymerizable material in a solvent, and providing a first environment proximate a first region of the coating and a different second environment proximate an adjacent region of the coating. The process further includes at least partially polymerizing the polymerizable material to form a composition that includes an insoluble polymer matrix and a second solution. The insoluble polymer matrix includes a plurality of nanovoids that are filled with the second solution, and a major portion of the solvent from the second solution is removed. A first volume fraction of the plurality of nanovoids proximate the first region of the coating is less than a second volume fraction of the plurality of nanovoids proximate an adjacent of the coating. An apparatus for the process is also described, and includes a web line, a coating section, a partial polymerization section, and a solvent removal section.
