Abstract
Optical assemblies include a light emitter having at least one layer of a transparent film, sheet or plate through which light emitted by the light emitter passes. A pattern of deformities of well defined shape on or in at least one side of the film, sheet or plate control an output ray angle distribution of light emitted by the assemblies to suit a particular application. The film, sheet or plate causes a change in color or color correction in the light emitted by the assemblies.
