Abstract
An LED diffuser may provide a more deterministic distribution of light from multiple discrete sources without relying on statistical scattering, and therefore, may reduce the type of efficiency losses associated with conventional diffusers as noted above. For example, an LED diffuser may have a smooth external surface that can be both aesthetically pleasing and easily cleanable. In still other embodiments according to the invention, an LED diffuser can include a single multilayer film. Further, an LED diffuser can include a plurality of multi-layer films that can provide additive diffusion properties. An LED diffuser can also be provided as a component of an LED light fixture.
